Install Vesta Control Panel (vestacp) on Centos 7 with PHP-FPM and PHP 7.2

by

I had few issues on my container and KVM on installing vestacp. Issues were like quite weird, such as-

  1. Post installation on KVM- it moved into emergency maintenance mode
  2. Post installation on LXC container- DNS resolution halted

After hours and hours of search, found few root causes-

  1. I have to withdraw quota with vestacp installation package
  2. No firewall on LXCcontainer

So let’s start.

Download installation script 

curl -O http://vestacp.com/pub/vst-install.sh

Run it 

bash vst-install.sh --nginx yes --phpfpm yes --apache no --named yes --remi yes --vsftpd yes --proftpd no --iptables no --fail2ban no --quota no --exim yes --dovecot yes --spamassassin yes --clamav yes --softaculous yes --mysql yes --postgresql no --hostname yourdomain.com --email yourmail@yourdomain.com --password yourpassword

You can also generate your installation command from vesta website:
