    It would be great to have a server clean-up script.

    Some of my directories are getting large:

    5.2G /usr
    1.3G /svr-setup
    30G /var

    I have a file with some clean up tasks, but maybe there could be a simple script created to do a server cleanup for people. Something that could also be setup to run via cron for people who have VPSs with not a lot of space.

    Code:
    Getting size of biggest folders on server

df -h
du -h --max-depth=1 /
du -h --max-depth=1 /home
du -h --max-depth=1 /usr
du -h --max-depth=1 /var

Delete nginx backup contents

# cd /usr/local/nginxbackup
# rm -rf /usr/local/nginxbackup/nginxdirbackup/*
# rm -rf /usr/local/nginxbackup/confbackup/*


Do ccache clean command above

# ccache -C

# cd /svr-setup/
# rm -rf /svr-setup/*

    Might want to check out these threads which will shed some light :)
    FYI, each time you upgrade Nginx an auto backup of nginx conf files and ssl directories is generated. See http://centminmod.com/nginx.html#autobackup and http://centminmod.com/configfiles.html
    so if you want to disable nginx auto backups set in persistent config file /etc/centminmod/custom_config.inc
    Code (Text):
    NGINXBACKUP='n'

    As to clean ups they only mask the issue of disk usage - the goal is to properly size your server for disk usage allowance. Otherwise you will mistakenly think you have XX GB of disk free space for site usage, but then forget that that disk space gets used by centmin mod disk utilising features like ccache cache, nginx auto backups and any backup scripts you add yourself and general downloads required in /svr-setup for php and nginx upgrades etc.

    i.e. imagine your /svr-setup directory was 3GB and you had 2GB free disk space. Then you clear /svr-setup giving you 3+2 = 5 GB free disk space. Then you upload 4GB of site files to your vhost web root. Leaving 1GB free. Then you go to try and upgrade nginx and php which downloads to /svr-setup and run of out disk space preventing you upgrading nginx and php.

    I didn't know about the NGINXBACKUP='n' which I'll set in the custom_config.

    I understand about people making sure they have the right disk space. I only suggested it so that people could clean up some space they have with a single script.

    I have plenty of space, so that isn't an issue for me.

    Yeah it's tricky to deal with as cleaning it up just gives folks false sense of available disk space. The nginx auto backups are handy. For insight see Nginx - Developer Overview: How Nginx is installed on Centmin Mod LEMP stack

    for example it backs up all nginx ssl certs as some folks accidentally deleted their ssl certs or vhost and are left without a backup which you can restore from.
