Featured Upgrade Nginx Insight Guide How to upgrade Centmin Mod + backing up customisations

Centmin Mod code upgrades via centmin.sh menu option 23 don't really make changes to other files needlessly. However, you really need to try and keep the code/routines that Centmin Mod uses up to date.

You can try the following by backing up the main files first and then do a fresh Centmin Mod code replacement by backing up and moving /usr/local/src/centminmod.

Replace branchname variable below with branch you want either 123.08stable or 123.09beta01 and type in SSH window the following:.

Code (Text):

branchname=123.09beta01

The cp copy commands backup the key files/vhost/ssl etc first. Remember to replace branchname with branch you want either 123.08stable or 123.09beta01

Code (Text):

branchname=123.09beta01
cp -a /etc/my.cnf /etc/my.cnf-old
cp -a /usr/local/lib/php.ini /usr/local/lib/php.ini-old
cp -a /usr/local/etc/php-fpm.conf /usr/local/etc/php-fpm.conf-old
cp -a /etc/centminmod /etc/centminmod-old
cp -a /usr/local/nginx/conf /usr/local/nginx/conf-old
cd /usr/local/src
mv centminmod centminmod-old
git clone -b ${branchname} --depth=1 https://github.com/centminmod/centminmod.git centminmod
cd centminmod
./centmin.sh

the last run for centmin.sh syncs any needed changes

---

then you can compare all the new and old directory and files and transfer them back manually if needed

Code (Text):

sdiff /etc/my.cnf /etc/my.cnf-old
sdiff /usr/local/lib/php.ini /usr/local/lib/php.ini-old
sdiff /usr/local/etc/php-fpm.conf /usr/local/etc/php-fpm.conf-old
diff -qr /etc/centminmod /etc/centminmod-old
diff -qr /usr/local/nginx/conf /usr/local/nginx/conf-old
diff -qr /usr/local/src/centminmod /usr/local/src/centminmod-old

example if file differs

Code (Text):

diff -qr /etc/centminmod /etc/centminmod-old
Files /etc/centminmod/email-primary.ini and /etc/centminmod-old/email-primary.ini differ

then use sdiff to see what the actual difference is

sdiff side by side view

Code (Text):

sdiff /etc/centminmod/email-primary.ini /etc/centminmod-old/email-primary.ini

sdiff side by side view only differences flag -s

Code (Text):

sdiff -s /etc/centminmod/email-primary.ini /etc/centminmod-old/email-primary.ini

Code (Text):

sdiff /etc/centminmod/email-primary.ini /etc/centminmod-old/email-primary.ini

These steps ensure you're running the latest routines that power Centmin Mod.

Folks, can post the output of the diff -qr commands and I will tell whether or not there's a better way to ensure some changes persist after Centminn Mod updates i.e. if you can use persistent config file method via /etc/centminmod/custom_config.inc etc

There's also a list of other file comparison tools you can use within SSH or locally on own PC listed at List of file comparison tools | Centmin Mod Community For windows I use BeyondCompare

 

yeah it could if you want to whip up a script yourself

but you can't do the file/settings diff compare in automated fashion, you'd need your own pair of eyes to determine which changes you'd want to keep or discard

 

Yeah I suppose. But good manual practice first is always good for beginners
