How to install the latest linux kernel (mainline) in CentOS 7 distro

Here you can see the steps to install the latest (mainline stable) kernel under CentOS 7, whether we need the latest driver, because we bought a new laptop released for the first time last month with the latest hardware or there is a hot fix of some nasty bug it is of no matter.
Here are the steps about installing the latest kernel to our CentOS 7, you must have root access:

STEP 1 Import the public key of the repository, which offer us the packages of the CentOS 7 mainline stable kernel (and some other kernels, like the Red Hat Enterprise Linux (RHEL) 6 and 7 and more, you can check out the site). The site of the repository is

https://elrepo.org/

Import the public key
```
#change to root user (skip the first line if you are root)
sudo su
rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
```
STEP 2 Check the latest version of the rpm install package of the repository, the command is under

To install ELRepo for RHEL-7, SL-7 or CentOS-7:

So at present the latest version is “7.0-3” and execute to wget to download the package for the repository elrepo:
```
wget http://www.elrepo.org/elrepo-release-7.0-3.el7.elrepo.noarch.rpm
```
STEP 3 Install the elrepo package with yum (you can do it with rpm command, but let yum manage all your packages and metadata for them!)
```
yum -y install ./elrepo-release-7.0-3.el7.elrepo.noarch.rpm
```
STEP 4 List the available kernels from the elrepo to choose the one you like
```
yum list available --disablerepo='*' --enablerepo=elrepo-kernel
```
To install the latest mainline kernel you must use package starting with

kernel-ml-*

at moment of writing the latest mainline kernel is

4.15.4-1.el7.elrepo

So execute
```
yum install -y --enablerepo=elrepo-kernel kernel-ml
```
And it will pull the

kernel-ml-4.15.4-1.el7.elrepo.x86_64

and install it

STEP 5 Check if you are going to boot the new kernel, you’ve installed and set the right one to boot

cat /boot/grub2/grubenv |grep saved
# GRUB Environment Block
saved_entry=CentOS Linux (3.10.0-693.el7.x86_64) 7 (Core)

And as you see, no it’ll not boot to the new kernel, so you must configure grub2 to boot your newly just installed kernel. First check all the installed kernels, set the right kernel and then it is mandatory to call

grub2-mkconfig

to update the grub2 configuration:

[root@srv ~]# awk -F\' /^menuentry/{print\$2} /boot/grub2/grub.cfg 
CentOS Linux (4.15.4-1.el7.elrepo.x86_64) 7 (Core)
CentOS Linux (3.10.0-693.el7.x86_64) 7 (Core)
CentOS Linux (0-rescue-0a26fe4b81d845209fb8958c8e29d600) 7 (Core)

The position 0 (YES, it starts from ZERO!) is “CentOS Linux (4.15.4-1.el7.elrepo.x86_64) 7 (Core)”, so you have two options to set it:

grub2-set-default 0
grub2-mkconfig -o /boot/grub2/grub.cfg

Check to see if everything is OK with

[root@srv ~]# cat /boot/grub2/grubenv |grep saved
saved_entry=0

or you can set the name of the kernel to boot with

grub2-set-default "CentOS Linux (4.15.4-1.el7.elrepo.x86_64) 7 (Core)"
grub2-mkconfig -o /boot/grub2/grub.cfg

Check to see if everything is OK with

[root@srv ~]# cat /boot/grub2/grubenv |grep saved
saved_entry=CentOS Linux (4.15.4-1.el7.elrepo.x86_64) 7 (Core)

STEP 6 is just to reboot

reboot

STEP 4 Verification of running the latest kernel

How to install the latest linux kernel (mainline) in Ubuntu (17.10) distro

Sometimes we need to install the latest kernel version of our linux distro (btw it is called “mainline” if you need to google something about it)! Whether we need the latest driver, because we bought a new laptop released for the first time last month with the latest hardware or there is a hot fix of some nasty bug it is of no matter. Here are the steps (and some troubleshooting) about installing the latest kernel to our Ubuntu install 17.10 (with old versions like 16, 15 and 14 should be the same):

STEP 1 is to choose our desired kernel from

http://kernel.ubuntu.com/~kernel-ppa/mainline/

Open this address in your favorite browser and choose the latest. In our example the latest kernel, which is no release candidate, 4.14.15. Enter the directory

http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.15.1/

and choose your build, for example amd64 for your 64bit setup (and for most cases choose -generic- one)

mkdir /root/latestkernel
cd /root/latestkernel
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.15.1/linux-headers-4.15.1-041501_4.15.1-041501.201802031831_all.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.15.1/linux-headers-4.15.1-041501-generic_4.15.1-041501.201802031831_amd64.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.15.1/linux-image-4.15.1-041501-generic_4.15.1-041501.201802031831_amd64.deb

STEP 2 after successfully downloading the 3 files just install them with “dpkg” (the package manager tool)
```
sudo dpkg -i linux-headers-4.15.1*.deb linux-image-4.15.1*.deb
```
STEP 3 is just to reboot your machine, the installation setup did everything you needed to load this kernel
```
reboot
```
STEP 4 Verification of running the latest kernel
```

Access Violation error, when compiling packages in Gentoo

Sometimes if you try to emerge a package in Gentoo you could receive error in the configure phase of the compilation process. The example below is with the emerging the PHP – dev-lang/php-5.6.33:5.6::gentoo, but could happen with many other packages, which are rather old and probably not maintained or the sandbox or even the portage packages are old.
So here is the error and the compilation stops:

You could try adding “-sandbox” to feature in “/etc/portage/make.conf”

FEATURES="-sandbox"

But

the sandbox feature is very important and should not be disabled by default.

And that’s why sometime when you disable it with “-sandbox” you still get access violation and you still cannot install/compile the package!
The thing is you see the error and you can fix it easily. The important part is the directory, which causes the error, in the above example with “dev-lang/php”, but could be any other Gentoo package, the problem is the writing permission for files in “/run” directory. So open the configuration file

/etc/sandbox.d/00default

and you’ll see the there is a variable called SANDBOX_WRITE, which accept paths. If you add to this variable at the end the directory “/run” or your access violated directory you’ll be able to install/compile your package with no problems, for the above problem the solution was:

SANDBOX_WRITE="/usr/tmp/conftest:/usr/lib/conftest:/usr/lib32/conftest:/usr/lib64/conftest:/usr/tmp/cf:/usr/lib/cf:/usr/lib32/cf:/usr/lib64/cf:/run"

Ryzen Threadripper kernel problems with PCIe – wifi, network, video problems

If you have Ryzen Threadripper (in my case 1950X) and Ubuntu 17.10 (because the others versions do not boot at all!) with the latest kernel 4.15.x and the default vmlinuz-4.13.0-21-generic you might experience frequently wifi, network cards and video cards problems like wifi disconnects and network cards lost connections and some kind of freezes for a second or two of the video! If you have Ryzen Threadripper 1950X and or ASUS ROG ZENITH EXTREME (or any other motherboard with the chipset AMD X399) and ubuntu 17.10 or probably any linux distro with any kernel you might experience really unstable system. Look at your dmesg and if you see something like

Apparently everything on the pci express could be affected! So till the kernel team fixes the issues, you can use the following workaround: add to the kernel boot parameters

pcie_aspm=off

Under Ubuntu you can add in the file

/etc/default/grub

the following line

GRUB_CMDLINE_LINUX="pcie_aspm=off"

And then execute

update-grub

the changes to take effect in the grub configuration. Then reboot the machine!

Under CentOS 7 the configuration file and the line to put are the same just the update of the grub configuration is different:

For UEFI-based systems execute:

grub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg

For legacy-BIOS systems execute:
```
grub2-mkconfig -o /boot/grub2/grub.cfg
```

*You should know what is your setup, probably UEFI-based, you could check in your boot directory, if there is /boot/efi/EFI/centos/grub.cfg you probably should use the option for UEFI-based, if you do not have any “efi” directory under “/boot” use the second option for legacy-BIOS.
Then reboot the machine!

xmr-stak GPU disabled after kernel or driver updated

Sometime when the user upgrades the kernel or the graphic card driver (NVIDIA or ATI) under Ubuntu (it is essentially the same with the other distros) we may encounter errors with xmr-stak and even not to be able to use our graphic card for mining!
Here we have an UBUNTU 17.10.1 and when we updated the kernel to the latest our mining xmr-stak software stopped using the NVIDIA card:

-------------------------------------------------------------------
[2018-02-16 12:17:11] : Start mining: MONERO
WARNING: NVIDIA Insufficient driver!
WARNING: NVIDIA no device found
[2018-02-16 12:17:11] : WARNING: backend NVIDIA disabled.
[2018-02-16 12:17:11] : WARNING: UNKNOWN_ERROR when calling clGetPlatformIDs for number of platforms.

[2018-02-16 12:17:11] : Starting 1x thread, affinity: 0.
[2018-02-16 12:17:11] : hwloc: memory pinned

As you can see the NVIDIA backend is disabled! In fact the driver seemed OK and loaded and even the X was working.
So in such a situation just reinstall the NVIDIA driver and install the software dependecies for the mining xmr-software (detailed explanation here)
Here what you can do:

sudo apt-get purge nvidia-*
sudo apt-get -y install libboost-all-dev libleveldb-dev libcurl4-openssl-dev libmicrohttpd-dev libminiupnpc-dev libgmp-dev  cuda nvidia-opencl-dev libmicrohttpd-dev libssl-dev cmake build-essential
sudo reboot

And you’ll have again an usable and properly installed GPU mining system.

Here is the log of the reinstallation, check it if you think you are going in the wrong direction, when purging the driver:

systemd can be used to run your application as a daemon

A nice feature of systemd is the scripts could be daemonized without any modifications of the scripts like standard stdin, stdout, stderr to be redirected to null (and even in some languages is not that simple!).
So if you want to run your ordinary script as daemon under a systemd linux distro, create a systemd service file in

/etc/systemd/system/myscript.service

Replace “myscript” with the nme of your script.

[Install]
WantedBy=multi-user.target

[Unit]
Description=<my_script_description>
After=syslog.target
After=network.target

[Service]
Type=simple
User=<run_as_user>
Group=<run_as_group_group>
ExecStart=<your_path_and_script_name_here>

# Give the script some time to startup
TimeoutSec=300
#EnvironmentFile=/etc/<filename>

[Install]
WantedBy=multi-user.target

So change the following according your needs:

<my_script_description> – description of your script/program with couple of words
<run_as_user> – the user under which will be executed
<run_as_group_group> – the group under which will be executed
<your_path_and_script_name_here> – the absolute path and filename to the script or program to be executed
Uncomment “EnvironmentFile” line if you would like to have different environment file for your script

And then you can run it with

systemctl start myscript

And you can enable it to start at boot

systemctl enable myscript

And also you can see the output of the script on syslog or with

systemctl status myscript

Here is an example of running a python script as a daemon with systemd.
The python script is

/usr/local/bin/mypythonscript.py

and the service name is

/etc/systemd/system/mypythonscript.service

Description=My python script daemon
After=syslog.target
After=network.target

[Service]
Type=simple
User=root
Group=root
ExecStart=/usr/bin/python /usr/local/bin/mypythonscript.py

# Give the script some time to startup
TimeoutSec=300

[Install]
WantedBy=multi-user.target

And you can see handful of information for the state of your script with

systemctl status mypythonscript

The uptime of your script and output if any

Avoiding Esc (escape) key, a key combination to simulate it

Writing the last howto there was an idea: how to simulate the ESC key, when the key is not available in our keyboard, which is very often these days. Mobile traffic is the ruler coming from mobile devices, of course! So why to limit console users (probably mainly admins?) only to desktop or “qwerty” keyboards? The tables could weight under 500 grams and event smartphones could be used to ssh to a server and what if you do not have ESC key, but need to use it? You can try the following combination:

The escape key can be replaced with pressing and holding CTRL and pressing “[” (left square bracket) = “CTRL+[”

So next time when trying to use ssh or console under Android or iOS or any device try this combination at lease it could be faster than selecting a menu for a predefined keys like ESC key.

vim – edit, save and exit, it is too simple!

Do not blame admins (or in general users, too) of using nano (pico) it is away too simple for simple tasks, which are probably the most cases under console.

- Save a file – press Esc key, then press and hold SHIFT and then press colons “:”, the bottom line of your screen will change and will start with colons “:”, then type the key “w” and then hit Enter key, so you’ve just saved the opened file.
  - 1. press Esc
    2. press and hold SHIFT
    3. press the key with colons “:“
    4. type “w“
    5. hit Enter key
- Save a file and quit – press Esc key, then press and hold SHIFT and then press colons “:”, the bottom line of your screen will change and will start with colons “:”, then type the key “x” and then hit Enter key, so you’ve just saved the opened file.
  - 1. press Esc
    2. press and hold SHIFT
    3. press the key with colons “:“
    4. type “x“
    5. hit Enter key
- Save all opened files – press Esc key, then press and hold SHIFT and then press colons “:”, the bottom line of your screen will change and will start with colons “:”, then type the key “wa” and then hit Enter key, so you’ve just saved the opened file.
  - 1. press Esc
    2. press and hold SHIFT
    3. press the key with colons “:“
    4. type “wa“
    5. hit Enter key
- Quit without saving, just quit the vim – press Esc key, then press and hold SHIFT and then press colons “:”, the bottom line of your screen will change and will start with colons “:”, then type the key “q!” and then hit Enter key
  - 1. press Esc
    2. press and hold SHIFT
    3. press the key with colons “:“
    4. type “q!“
    5. hit Enter key
Enable auto save with two ESC keys – create or edit file

~/.vimrc

Add the following line:
```
map <Esc><Esc> :w<CR>
```

* The Esc can be avoided

The escape key can be replaced with pressing and holding CTRL and pressing “[” (left square bracket) = “CTRL+[” and if your “[” is hard typing, you can try CTRL plus “c” = “CTRL+c”, all this is needed to be sure you are not in vim’s insert mode. Avoiding Esc – escape button could be useful under not qwerty keyboards of the mobile devices – smartphones, tablets and so on.

How to proper enable the selinux in a CentOS7 installed server

These days many dedicated servers are offered with automation installation of operating systems and it have never been so easy and fast to pay a server and to get it up in minutes! Yes, we are talking for dedicated machines not virtual servers or cloud ones, but many cloud ones are in the same situation, when the host uses full virtualization.
It is fast, you can choose from many different linux distros and the installation is unattended and happens immediately, but in most cases the selinux is disabled, because is more easy for the support, for the user, for the admin, and for the offered preinstalled software…If you do not have some strange software in most cases it is advisable to enable the selinux, because it is of great security enhancement for your server and for the software in general. It is very simple to enable selinux, but there is an additional step, which if you omit, the server will probably get unusable (probably you won’t be able even to ssh it or login). These steps are tested under CentOS7, but probably works in all other distros, which support selinux!
So here are the steps:

STEP 1) Enable selinux in configuration

Edit the configuration file in

/etc/selinux/config

SELINUX=enforcing

STEP 2) relabel the file system

When using the selinux, there are labels (extended attributes of the file system), which are additional layer of security. Every system comes with prebuild rules instructing what label is set in which file or directory, so when you enable the selinux you must relabel the entire file system (or at least the root partition, to be able to boot normally). This is done with just a line of code below:

touch /.autorelabel

STEP 3) reboot

To take effect the changes made above the server must be rebooted.

reboot

The init process will find the file from step 2 “/.autorelabel” and will initiate a proper relabel according the current selinux rules file, then the server will be rebooted automatically again, the relabel could take time and it depends on the number of files you have in your server, just keep patient.
After the second reboot (which is automatically after the relabeling)

4) Recommendations

USE SELINUX, do not disable it! In most cases it is really simple to configure it in minutes for the need of your special software and for the generic one bet it there are rules offered in the distro’s packet system.

4) Post install check

You can check if the selinux is enabled with

[root@srv ~]# getenforce 
Enforcing
[root@srv ~]#

Install xmr-stak 2.2 in a machine with NVIDIA video card under Ubuntu 16.04 LTS (only commands , real output and benchmark)

Here is the Part 2 of the Install xmr-stak 2.2 in a machine with NVIDIA video card under Ubuntu 16.04 LTS. The Part 2 is just all executed commands, which could be put in a bash file to automate the installation of the machine and the compilation of the xmr-stak and the output for a much clear example with real life example with output. Here you’ll find no explanations, which are included in the “Part 1” (see link above).
So only three sections here, first the bash commands and then the output of executed commands, only the installation of the packets with apt-get is trimmed because of the long output! The example is executing first sudo su to get to the root user, if you do not feel good you can skip the root and adjust it to the user you like with sudo. The second is the output of the commands and the third is the benchmark and hardware information of the machine used for this howto.

./xmr-stak

It’s worth mentioning the configuration of xmr-stak first run from Part 1:
Just enter your monero (or other cryptocurrency using cryptonight algorithm like Electoneum, Intensecoin and so on), follow the questions and in our case are shown below, the question start with “-” line and my answers are the next lines, yours will be different, especially in the part of the “Pool address”, which is the address of the pool you use, the username, which is the crypto currency public address you have (now, there is a fake address, DO NOT USE IT, you’ll mine and use your resources for nothing!!! Check your public address and put it there!), the Password, which is blank or your email (some pools’ software shows better statistics with your email, not required in most cases)

2. Here is the all real output (just the configuration of Pool address, Username and Password are changed for security reasons, use your own)

3. Extra section – noting the benchmark.

This installation is done in amazon EC2 g3.4xlarge instance type, which has 1 GPU with 8 GiB RAM (2048 parallel processing cores), the processor is 16vcpu of Intel Xeon E5-2686 v4 (Broadwell) processors running at 2.7 GHz, Main Memory 122 GiB. You can see the virtual server is using “NVIDIA Corporation GM204GL [Tesla M60] (rev a1)”. So the benchmark of the virutal server is total of 700.6 hashes per second of CryptoNight with highest value of 1119.1 hashes per second.
