Properly uninstall vestacp in centos

[mattluu]

Sorry I don't know where to put this topic . Can moderators help me move it to right place please?

Here is my problem. I'm writing a script that used for automatically install, uninstall, check version, start, stop... for vestacp and its components like mysql, postgre, memcached ....

When I tried to test uninstalling vestacp on my CentOS 6.5 , I checked service after uninstalling with steps on vesta's document. But later I found out that mysqld, named, exim, messagebus ... were still running. They were all program installed by vesta. And iptable still had some lines like fail2ban, vesta-iptables... I couldn't reinstalling vesta too because it said me those services still running.

So I decied to uninstalled them and reset my iptables . Here is the script

Code: Select all

service "vesta" stop
# kill named process
kill "$(pgrep named)"
yum -y remove vesta*
rm -f /etc/yum.repos.d/vesta.repo
# PACKAGES is an array i made with "httpd","apache","fail2ban","mysqld""nginx","dovecot","vsftpd","exim","messagebus" to check if they still exists after uninstalling vesta
for i in "${PACKAGES[@]}"; do
      service.exists $i && service $i stop >/dev/null && writeln "Unistalling $i" && yum -y remove $i
done
# delete admin user and cronjobs
passwd -l admin >/dev/null
crontab -r -u admin >/dev/null
userdel -r admin
rm -f /home/admin
# reset iptables rules
iptables --flush && service iptables save && service iptables stop && service iptables start && iptables --list
rm -rf /usr/local/vesta >/dev/null

Everytime I executed this function, I lost connection to my vps through putty, and couldn't access to vps anymore. So I had to reinstall the vps 's OS.

Could you please point me out why I got those errors and show me how to improve my script for a chance a centos user want to reinstall their vestaCP but can't uninstall properly?

Thank you in advance

You probably forgot that default policy is DROP for INPUT in iptables. As soon as you clear rule allowing SSH traffic it's gone.

Issue this command:

Code: Select all

iptables --policy INPUT ACCEPT

Before clearing all rules
