Featured Upgrade Nginx Redis Insight Guide Tracking Centmin Mod Config Changes Which Are Not Automatically Synced

It was discussed at https://community.centminmod.com/th...onf-include-file-cache-control-headers.11728/ of how to track some Centmin Mod config file changes which do not automatically get sync'd on Centmin Mod centmin.sh menu option 23 submenu option 2 updates and needing manual changing and visual comparisons for.

Why?

Centmin Mod generally does not auto change config files after post initial install unless it's a security or severe bug fix. The reason is because, end users can customise their config files themselves for their needs and auto making changes may break the end users customised settings.

Files To Track

These are some of the files which may get changes which may need manual updates or have had dynamic updates made on the defaults based on your server specs

• /usr/local/nginx/conf/nginx.conf
• /usr/local/nginx/conf/conf.d/virtual.conf
• /usr/local/nginx/conf/staticfiles.conf
• /usr/local/etc/php-fpm.conf
• /usr/local/nginx/conf/php.conf
• /usr/local/nginx/conf/drop.conf
• /usr/local/nginx/conf/errorpage.conf
• /usr/local/nginx/conf/pagespeed.conf
• /usr/local/nginx/conf/pagespeedhandler.conf
• /usr/local/nginx/conf/pagespeedstatslog.conf

I outlined some tips for this including using sdiff/diff commands in SSH to visually check for differences with Centmin Mod copy in /usr/local/src/centminmod and the live server config files in play

i.e.

server copy /usr/local/nginx/conf/nginx.conf
vs
centmin mod copy /usr/local/src/centminmod/config/nginx/nginx.conf

Notes:

• sdiff could cut off characters in display so diff -u command is more accurate

sdiff:

---

You can use sdiff to do diff side by side compare within ssh provided your ssh client is configured with wider screen width buffer

i.e. sdiff with width of 200 to compare the latest copies locally available in /usr/local/src/centminmod with ones live on server

Code (Text):

sdiff -w200 /usr/local/nginx/conf/nginx.conf /usr/local/src/centminmod/config/nginx/nginx.conf
