Here's how I installed WP-CLI with ISPCongfig 3, and it's available globally for clients with jailkit installed. First I followed this guide to allow PHP in SSH for jailed users - http://www.faqforge.com/linux/add-php-in-ssh-jail-ispconfig-3/ The I ran these commands: Code: wget https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar --no-check-certificate php5 wp-cli.phar --info chmod +x wp-cli.phar mv wp-cli.phar /usr/bin/wp Code: nano /etc/jailkit/jk_init.ini Add to the end of file Code: [wp] comment = WordPress Command Line executables = /usr/bin/wp includesections = php Run the command: Code: jk_init -c /etc/jailkit/jk_init.ini -f -k -j /var/www/clients/client1/web1 wp Next, login to ISPConfig 3 and navigate to - ISPConfig 3 > System (Tab) > System > Server Config > (select server) > Jailkit Add the word "wp" separated by a white space at the end of the "Jailkit chroot app sections" field. SSH to the jailed shell and test. Code: [email protected] Hope this helps someone. If anyone sees any security issues, please let me know.
