phpmyadmin.sh installed 404 error when accessed

404 for the phpmyadmin url ? did you restart nginx and php-fpm services ?

check phpmyadmin log (centminmod_phpmyadmin_install_*.log) in /etc/centminlogs output and share on pastebin.com or gist.github.com

 

is THBX-Cloud001-I002 a legit web browsable hostname ? or you just replaced it for public posting ? as you need to ensure the the main hostname of the server is resolvable as per Getting Started Guide Step 1 - phpmyadmin installer uses the main hostname of the server to server the phpmyadmin direct off of

 

also check the phpmyadmin access and error logs for clues from your vhost file for phpmyadmin

Code (Text):

        access_log              /var/log/nginx/localhost_ssl.access.log     main buffer=32k;
        error_log               /var/log/nginx/localhost_ssl.error.log      error;

 

2nd vps a newer install of centmin mod than 1st vps that is working ?

newer installs need working main hostname in server_name and must not match domain set in server_name in any other created nginx site domains via centmin.sh menu option 2 otherwise yes you will get 404

main hostname's server_name needs to unique

 

both vps have multiple wordpress sites ?

probably need to enable nginx debug mode to troubleshoot so moving your posts to own thread in addon forums

 

Latest update on September 14, 2015 to Centmin Mod 1.2.3-eva2000.08 stable (123.08stable) and higher has added Nginx debug mode support. Nginx debug mode is disabled by default.

To enable, edit centmin.sh and change variable NGINX_DEBUG=n default to NGINX_DEBUG=y and recompile Nginx via centmin.sh menu option 4 and then setting error_log in nginx vhosts to debug as outlined at nginx.org/en/docs/debugging_log.html & wiki.nginx.org/Debugging.

You do not want to leave Nginx debug mode running forever, so after debugging, set NGINX_DEBUG=n in centmin.sh and recompile Nginx again via centmin.sh menu option 4 and remove error_log debugging mode to disable Nginx debug mode again.

To update your Centmin Mod builds code for Nginx debug mode support if you do not have a NGINX_DEBUG variable in centmin.sh, follow instructions at centminmod.com/upgrade.html and respective version threads below:

• Centmin Mod 1.2.3-eva2000.08 stable install & update thread
• Centmin Mod 123.09beta thread

Centmin Mod is provided as is, but you can try debugging mode for Nginx for further troubleshooting if you have problems with Nginx (i.e. segfaults / signal 11 issues) as outlined at nginx.org/en/docs/debugging_log.html & wiki.nginx.org/Debugging.
