Service unavailable

    Hi,


    Today suddenly my apache service unavailable.
    Service running, but all my domains have Error 503, Service unavailable.
    imscp panel unavailable too, but service running.


    So I try to restart services, not helped.
    After it, run the following command:

    Code
    1. perl /var/www/imscp/engine/setup/imscp-reconfigure -danv


    All went well, but after only i-mscp panel worked.
    I try to change a user PHP version from 7.0.13 to 5.6.32 and now that site working, but noone else...


    What is a problem? I'm not modified my server at last 3 weeks.


    Apache error log:

    We cannot help here as the log are irrelevant. You should avoid reconfiguring i-MSCP before investigate the problem source. Nothing is magic. The services don't stop working for nothing. Somehow, you have surely done something.

    Thank you for tried to help.


    Now, all domain on this server works. ?(
    I don't understand it, because what I only do is reconfiggure and switched one domain PHP version from 7.0.16 to 5.6.32


    Next time I'll investigate when I have time, but today I did not have more than 15 minutes.

    Ok, I think I found the problem.

    Well, you should use UDS instead of TCP...

    @Nuxwin
    Can you help me in this?
    Now, all my customer's domain stoped again, imscp_panel not worked, and apache2 dead....

    Edited once, last by Dylan ().

    Ok, I found the command:



    Code
    1. /var/www/imscp/engine/setup/imscp-reconfigure php

    Switch PHP to UDS
    All went well, after it, imscp panel not worked, but service running.
    apache2 dead
    php7.1-fpm running


    So I start apache2 manually and now all works.
    I hope it solved the problem... :|
