I’m reviewing all the “tweak settings” of my cPanel server.
I’ve just read this:
Jail Apache Virtual Hosts using mod_ruid2 and cPanel® jailshell.
If mod_ruid2 is compiled in via EasyApache, mod_ruid2 is enabled, and a user has their shell set to jailshell or noshell, enabling this option will chroot() a user’s Apache Virtual Host into the cPanel® jailshell environment. Each user will require 14 bind mounts. While modern Linux supports a very large number of bind mounts, many processes read /proc/mounts. Reading /proc/mounts can be quite expensive when it becomes large.
Anyone have a better explanation? Is this something I should use with less than 30 accounts (most of them are Wordpress). I’m not using Cloudlinux.
Allow cPanel & WHM to determine the best value for your MySQL innodb_buffer_pool_size configuration?
cPanel & WHM will use your total number of tables to adjust the innodb_buffer_pool_size value during each MySQL restart.
How safe is that?
