How to Install CloudLinux with LVE Manager and CageFS

When you want to implement server resource isolation and user limits. This article explains how to install CloudLinux with LVE Manager and CageFS.

The process below explains how to install CloudLinux on your server.

Download the cldeploy script using the command:

wget https://repo.cloudlinux.com/cloudlinux/sources/cln/cldeploy

Execute the script using the command:
```
sh cldeploy -k 
```
activation_key is the activation key for your CloudLinux license.

If you have an IP-based license, use the command:
```
sh cldeploy -i
```
Since we have a layer of visualization, we need to edit the kernel parameters of CloudLinux before the server is rebooted. Use the command:
```
vi /boot/grub/menu.lst 
```

Here, edit the line below and append acpi=off:

kernel /boot/vmlinuz-2.6.32-531.17.1.lve1.2.57.el6.x86_64 ro root=UUID=8a5e62f9-f013-46bd-8d81-6f32ee929d93 consoleblank=0 crashkernel=auto SYSFONT=latarcyrheb-sun16 LANG=en_US.UTF-8 KEYTABLE=us nohz=off

Now, the file will appear as indicated below:

default=0

	timeout=5

	serial –unit=0 –speed=115200

	terminal –timeout=5 serial console

	title CloudLinux Server (2.6.32-531.17.1.lve1.2.57.el6.x86_64)

	root (hd0,0)

	kernel /boot/vmlinuz-2.6.32-531.17.1.lve1.2.57.el6.x86_64 ro root=UUID=8a5e62f9-f013-46bd-8d81-6f32ee929d93 consoleblank=0 crashkernel=auto SYSFONT=latarcyrheb-sun16 LANG=en_US.UTF-8

Reboot the server using the command:
```
reboot
```
The server will now be running CloudLinux with LVE. You can check the same using the command:
```
uname -a
```
The output would appear as indicated below, depending on the version of the kernel installed

Linux 2.6.32-531.17.1.lve1.2.57.el6.x86_64 #1 SMP Sat Jun 7 08:40:25 EDT 2014 x86_64 x86_64 x86_64 GNU/Linux
Now, install LVE Manager using the command:
```
yum install lve-utils
```
Ensure that proper lock files are created in /proc, using the command:
```
/etc/init.d/lvestats start
```
Restart the LEV service using the command:
```
/etc/init.d/lveclt restart
```
Recompile EasyApache using the command:
```
usr/sbin/cpanel-compile-suexec.sh
```
By default, all the domain names are added to Cagefs. However, after recompiling EasyApache, it is recommended that the users who have been added to CageFS be updated. Use the command:
```
/usr/sbin/cagefsctl –force-update
```

This completes the configuration of CloudLinux and CageFS on your server.
