I need to install the mbstring module on my system. How should I do this?

Greetings,

If you are running cPanel, you can do this very easily by following the steps below:

1. First login to WHM as root.
2. Then go and click on Software -> EasyApache.
3. If prompted to upgrade, do so then repeat "Step 2".
4. Begin customizing based on the current profile.
5. Proceed through the screens until you get to "Step 5".
6. On "Step 5," click on "Exhaustive Options"
   Under PHP, check the checkbox for MBString
7. Proceed with Build & Compile Process. Make sure you wait for the build to complete.

Be sure to use the web panel, not yum , to install modules with cPanel. The rpm system for PHP and modules can end up causing a broken PHP system on the machine, since it will be in direct conflict with the cPanel-built PHP and PHP modules done via EasyApache.

Best,
