Topic: iRedAdmin - lost nginx config, reinstall of ONLY iredadmin possible?

==== REQUIRED BASIC INFO OF YOUR IREDMAIL SERVER ====
- iRedMail version (check /etc/iredmail-release): 0.9.9
- Deployed with iRedMail Easy or the downloadable installer? Yes
- Linux/BSD distribution name and version: Ubuntu16.04LTS i386
- Store mail accounts in which backend (LDAP/MySQL/PGSQL): MariaDB
- Web server (Apache or Nginx): Nginx
- Manage mail accounts with iRedAdmin-Pro? No
- [IMPORTANT] Related original log or error message is required if you're experiencing an issue.
====

Hello, I installed iRedMail completely and everything was ok, so I switched all our mail to that server. But then we decided to install another application that re-wrote Nginx config for sites-available (& enabled). Of course, no backup was made smile We restored everything related to work with php section (we use 5.6 for old cms & 7.2 for everything else including Roundcube) through unix socket

Any my nginx config caused errors - 502, then Internal Server Error, etc. The problem seems to be in socket - I am unable to find normal config or manual on how to setup python app to work under nginx.

Restarting of iredadmin service caused failure. So now I need to reinstall and re-configure manually iRedAdmin console.
Please advise on any manual / procedure description on how to return it back to life.

Current iRedAdmin service status:

Commands below should fix it:

chown -R iredadmin:iredadmin /opt/www/iRedAdmin-*
chmod -R 0555 /opt/www/iRedAdmin-*
service iredadmin restart

Re: iRedAdmin - lost nginx config, reinstall of ONLY iredadmin possible?

Hello,

iredadmin app is located in folder /opt/www/iredadmin, so i modified commands accordingly

This commands was applied, but nothing happens - still getting error:

Maybe should modifi uwsgi config (/usr/share/uwsgi/confdefault.ini) with some permissions?

#set mode of created unix socket
chmod-socket = 664 -> to 666?

You got it wrong, do not modify the commands i wrote in previous reply.

/opt/www/iredadmin (in lower cases) is a symbol link to /opt/www/iRedAdmin-0.9.4 (the version number may be different on your server), so we need to change owner/permission on iRedAdmin-0.9.4 instead, not /opt/www/iredadmin.

Well, I renamed iRedAdmin-0.9.4 to just 'iredadmin' earlier and removed symlink
Now I tried to make an upgrade of iRedAdmin, re-created symlink and got folder iRedAdmin-0.9.4

But after sudo permissions was set, it returns an error anyway:

Re: iRedAdmin - lost nginx config, reinstall of ONLY iredadmin possible?

Fixed, caused by incorrect file permission of its parent directory /opt/www.
It was owned by 'www-data:www-data' with permission 0770, should be owned by "root:root" with 0755.
