Resolved Nginx start timeout

[inigo]

I have been looking for this issue and tried all fixes that I found in this forum + internet and I could not fix the issue.

This is a brand new installed Plesk 12.5.30 Linux server on a clean Centos 7 proxmox container with over 30GB of disk space and 8GB Ram.

Installed plesk with the wget auto_install sh script from odin webpage, and it is running the demo Web Host license valid till April.

After restart, the website server is offline. Going to Tools and settings > Services, Proxy nginx is off.

1 When I click to start it: Error: Unable to make action: Unable to manage service by nginxmng: ('start', 'nginx'). Error: [2016-03-07 09:53:21] ERR [util_exec] proc_close() failed ['/usr/local/psa/admin/bin/nginx_control' '--start'] with exit code [255]
Can not start proxy server:

SOMETIMES, THE server starts and I can see the webpages, but the result in the panel is the same ERROR and the services page still shows nginx stopped with the start option.




2 In SSH, a /usr/local/psa/admin/bin/nginxmng --enable returns this:
[2016-03-07 09:53:21] ERR [util_exec] proc_close() failed ['/usr/local/psa/admin/bin/nginx_control' '--start'] with exit code [255]

Can not start proxy server:





3 If I run systemctl start nginx , returns this:
Error getting authority: Error initializing authority: Error calling StartServiceByName for org.freedesktop.PolicyKit1: GDBus.Errorrg.freedesktop.DBus.Error.TimedOut: Activation of org.freedesktop.PolicyKit1 timed out (g-dbus-error-quark, 20)

Failed to start nginx.service: Connection timed out





4 The systemctl status nginx shows:
PID file /run/nginx.pid not readable (yet?) after start.
Mar 07 09:53:20 myhost.com systemd[1]: nginx.service start operation timed out. Terminating.
Mar 07 09:53:21 myhost.com systemd[1]: Failed to start Startup script for nginx service.


I can confirm that the file /run/nginx.pid does not exist.




5 For debug purposes, I disabled SELinux:

[root@www run]# sestatus
SELinux status: disabled






6 Desperate, as suggested by Igor in another post, I ran the plesk repair web tool with this 2 errors as result:

Repair server-wide configuration parameters for web servers? [Y/n] y

Can not reload proxy server:

ANY HELP IS VERY APPRECIATED, I RECREATED THIS VIRTUAL MACHINE 3 TIMES, and THE SAME RESULTS ALL THE TIMES.

Hi Inigo, were you able to solve the problem?

Hi,

its not a plesk bug, its systemd...

You must edit the "UNIT" section to:

[Unit]
Description=Startup script for nginx service
After=network-online.target remote-fs.target nss-lookup.target
Wants=network-online.target

in "/usr/lib/systemd/system/nginx.service".

Attached my full file:

[Unit]
Description=Startup script for nginx service
After=network-online.target remote-fs.target nss-lookup.target
Wants=network-online.target

[Service]
Type=forking
PIDFile=/run/nginx.pid
EnvironmentFile=-/etc/sysconfig/nginx

.include /etc/sysconfig/nginx.systemd
# tuning of limits settings:
# 1. fill required limits as described in systemd.exec(5)
# nginx.systemd content example for number of open files:
# [Service]
# LimitNOFILE=8192
# 2. restart service

ExecStartPre=/usr/bin/test $NGINX_ENABLED = "yes"
ExecStartPre=/usr/sbin/nginx -t
ExecStart=/usr/sbin/nginx

ExecReload=/usr/bin/test $NGINX_ENABLED = "yes"

Ok, I've solved my problem.

This problem whit /usr/bin/test is because it's not possible start/stop a process from panel and start/stop from console at the same time. If the process start from panel, should stop from panel.

Thanks for all!
