You must have ispconfig installed and jailkit.

Install Composer

cd ~
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('sha384', 'composer-setup.php') === 'e0012edf3e80b6978849f5eff0d4b4e4c79ff1609dd1e613307e16318854d24ae64f26d17af3ef0bf7cfb710ca74755a') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"

php composer-setup.php --install-dir=/usr/local/bin --filename=composer

php -r "unlink('composer-setup.php');"

Add code to jailkit to use as shell user

Add to /etc/jailkit/jk_init.ini

[php]
comment = the php interpreter and libraries
executables = /usr/bin/php, /usr/bin/php7.3
directories = /usr/lib/php, /usr/share/php, /usr/share/php, /usr/share/php-geshi, /etc/php,/usr/share/zoneinfo, /etc/snmp, /usr/share/snmp
includesections = env

[env]
comment = environment variables
executables = /usr/bin/env

[composer]
comment = Dependency Manager for PHP
executables = /usr/local/bin/composer
#directories = /usr/share/composer

Install Virtual Machine Manager(libvirt) in Manjaro

STEP 1: Launch Terminal and enter the following command to install KVM and necessary dependencies.

sudo pacman -S virt-manager qemu vde2 ebtables dnsmasq bridge-utils openbsd-netcat
STEP 2: The next two steps are very important and often ignored by many users. Make sure to complete it else, you will get error “adduser: The group `libvirtd’ does not exist” when you run the Virtual Machine Manager after installation is complete!

Enable the service by entering the below command:

sudo systemctl enable libvirtd.service
STEP 3: Start the service using below command:

sudo systemctl start libvirtd.service

sudo groupadd --system libvirt
sudo usermod -a -G libvirt $(whoami)
newgrp libvirt
//Verify that user is added to libvirt group.
id $(whoami)

Open the file /etc/libvirt/libvirtd.conf for editing.

sudo vim /etc/libvirt/libvirtd.conf
Set the UNIX domain socket group ownership to libvirt, (around line 100)
unix_sock_group = "libvirt"
Set the UNIX socket permissions for the R/W socket (around line 102)

unix_sock_rw_perms = "0770"
Restart libvirt daemon after making the change.

sudo systemctl restart libvirtd.service
