| + | ===== Setting Cache Root to a Secondary Disk (with CageFS) ===== | ||
| + | In some environments, you might run with normal hard drives for ''/home'', but you want to place your ''lscache'' data on SSDs, such as ''/ssdcache/lscache''. This requires a bit of special configuration both within your CacheRoot setting as well as CageFS. | ||
| + | |||
| + | Make sure that your secondary disk is mounted on ''/ssdcache'' and that the directory ''lscache'' exists. | ||
| + | |||
| + | Within ''/etc/apache2/conf.d/userdata/lscache_vhosts.conf'', you'll have to add the following content: | ||
| + | |||
| + | <IfModule Litespeed> | ||
| + | CacheRoot /ssdcache/lscache/$vh_user | ||
| + | </IfModule> | ||
| + | |||
| + | The above 3 lines will tell LiteSpeed that the vhost-level cache corresponds to a dynamic LSCache folder which matches the user of the VirtualHost. This will ensure that the cache for each customer gets separated. | ||
| + | |||
| + | If you're using CageFS, you also need to expose this within the caged environment. Luckily, it's rather easy to do! | ||
| + | |||
| + | In your ''/etc/cagefs/cagefs.mp'' file, you can add the line: | ||
| + | |||
| + | %/ssdcache/lscache | ||
| + | |||
| + | By using ''%'' in front of the path, it utilizes the "split by username" functionality added in CageFS 5.3.1, so what will be exposed within CageFS will be ''/ssdcache/lscache/$user''. | ||
| + | |||
| + | To apply the above changes, we first rebuild the httpd configuration in cPanel and restart LiteSpeed: | ||
| + | |||
| + | /scripts/rebuildhttpdconf | ||
| + | /scripts/restartsrv_httpd | ||
| + | |||
| + | Afterwards, we have to remount CageFS for all users, so the new path becomes available within CageFS: | ||
| + | |||
| + | cagefsctl --remount-all | ||
| + | |||
| + | Your LSCache data will now be stored on the SSD instead of your hard drive! | ||
