Error on enabling nginx

[DMKlein]

I wanted to activate nginx on my server als describes on http://kb.odin.com/en/119595
Installing was no problem, but when i try to enable nginx, i always get errors:

/usr/local/psa/admin/sbin/nginxmng -e

solved my problem. Both logfiles have no errors. There are also no further informations in the panel.log

Anybody an idea?

Hi DMKlein,

what is the output of "/usr/local/psa/admin/sbin/httpdmng --reconfigure-all" ?

 

[DMKlein]

Nothing:

server:~# /usr/local/psa/admin/sbin/httpdmng --reconfigure-all
server:~#

Hi DMKlein,

please post the results of:

/usr/local/psa/admin/sbin/nginxmng -s
/etc/init.d/nginx status
/etc/init.d/nginx stop
/etc/init.d/nginx start​

Hi DMKlein,

as you can see, your output

server:~# /usr/local/psa/admin/sbin/nginxmng -s
Disabled

states, that your NGINX - usage is disabled at the moment. Please activate it again with the command: "/usr/local/psa/admin/sbin/nginxmng -e".

Even if you still might get the error as shown in your initial post, you still should be able to start NGINX with the command "/etc/init.d/nginx start". Please reply, if the start - command works as expected. It it does, please retry again the command "/usr/local/psa/admin/sbin/nginxmng -e", when NGINX is running.


If NGINX doesn't start with the command "/etc/init.d/nginx start", please have a closer look on the possible error - message and/or the NGINX - log and configurations files for further investigations.

I created the directory and added the owner to nginx:nginx.

I created it too (and changed the owner). Now it seems to work:

server:~# /etc/init.d/nginx start
[ ok ] Starting NGINX: nginx.
server:~# /etc/init.d/nginx status
[ ok ] nginx is running.

Hi DMKlein,

the folder "/etc/nginx/plesk.conf.d/vhosts" should have the rights "root:root" and the depending configuration - files should be all symlinks for each domain(s) and subdomain(s) on your server, as for example "/var/www/vhosts/system/YOUR_DOMAIN.COM/conf/nginx.conf", "/var/www/vhosts/system/YOUR_SUB-DOMAIN.DOMAIN.COM/conf/nginx.conf", etc.... and should be created when you use "/usr/local/psa/admin/sbin/httpdmng --reconfigure-all".

the folder "/etc/nginx/plesk.conf.d/ip_default" should have the rights "root:root" and the depending "IP - default" configuration ( symlink to the conf - file for "/var/www/vhosts/system/YOUR_DOMAIN_FOR_THE_IP_XXX.XXX.XXX.XXX/conf/nginx_ip_default.conf" ) should be created when you use "/usr/local/psa/admin/sbin/httpdmng --reconfigure-all".

You should have as well the folders "/etc/nginx/plesk.conf.d/webmails" with rights for "nginx:psacln" and "/etc/nginx/plesk.conf.d/forwarding" ( rights = "root:root" ) and again, the depending symlinks ( if "webmail" and/or "forwards" are used ) should be created, when you use "/usr/local/psa/admin/sbin/httpdmng --reconfigure-all".
