Resolved No log-in page after yum update

Papacico

Papacico

New Pleskian
Hello,
I am on Plesk Onyx 17.8.11 Update #84
after trying to install this ftp package vsftpd-3.0.2-25.el7.x86_64 (which is failed)
and after having run: yum update I am not able anymore to reach the plesk login page at: https://servername:8443
I have run: "plesk repair installation" but did not help.
I have followed some topic in which they tell me to run this: "service plesk-web-socket restart"
but I get this error "1018 Failed to restart plesk-web-socket.service: Unit not found."
Rebooting the server did not help either.

So I have these questions:

  1. Where are plesk error stored as I can't find any error in de httpd error_log when trying to access the login page
  2. Should I consider reinstalling Plesk?
  3. Will plesk re-installation affecting my existing domains or other server configuration?
Thank you

First of all, check that you can start sw-cp-server service.

Looks like sw-cp server misconfiguration. Try to do the following:

Backup the current sw-cp-server config:

# cp /etc/sw-cp-server/config /etc/sw-cp-server/config_backup

Open /etc/sw-cp-server/config in any text editor and set the "fastcgi_buffers" directive as follows:

fastcgi_buffers 16 16k;

Restart sw-cp-server:

# service sw-cp-server restart

pls see the config file configuration at the moment
 
Why dot at the end of the line? It should be

fastcgi_buffers 16 16k;
 
On my test Plesk server:

# grep fastcgi /etc/sw-cp-server/config
"'$fastcgi_script_name' '$fastcgi_path_info' '$document_root'";
fastcgi_max_temp_file_size 0;
fastcgi_buffers 16 16k;
fastcgi_buffer_size 32k;
fastcgi_pass_header X-Accel-Buffering;
fastcgi_read_timeout 600;
fastcgi_send_timeout 600;
