EA4 provisioned/updated profile now Blank WHM & Sites not working

[curios]

Greetings,

A few weeks/months ago I migrated my Godaddy Cpanel VPS from EA3 to EA4, and once the migration was completed, I edited the migrated template/profile to remove php55.

Server has been running with Apache 2.4 and php56 and for these past weeks/months it seems to trigger more warnings than when it was on EA3 Apache 2.2 (1GB mem)

A few hours ago, looking at the profiles for EA4 noticed there was one that was identified as being the default cpanel profile (that supported multiple sites) php55/56/7 etc.

I selected that profile, and ran system update and that is when the chaos started

After the process ended my websites stopped working and the error log displayed memory errors. Rebooted the server and then WHM wouldn't start, after some time I was able to login only to receive a blank page.

DNS works, email works, just the sites are down and I have a very high memory use, which apparently it is what is preventing WHM from working correctly as well.

Any suggestions to get this server back on track. I will eventually move to a 2GB server, but would like to correct this one now.

Any suggestions?

Thank you

Hello,

Do you know the date that you updated to the new EasyApache 4 profile? If so, you can use a command like this to see which RPMs (e.g. a specific MPM, Ruid2) were erased when you switched profiles:

grep Erased /var/log/yum.log|grep "Sep 13"

Replace "Sep 13" with the date that you switched to the default EA4 profile, and the output should give you a better idea of which RPMs were previously installed. Once you have that information, you can customize the existing EasyApache 4 profile to install the previously removed RPMs.

Thank you.

Thank you Michael.

The profile I selected a few hours ago was "All PHP Options + ZendGuard" which was obviously a mistake. Just got a new 2GB CPanel server setup so I was able to see exactly what I selected in the older server.

Since you mentioned the yum log and the keyword "customize" It occurred to me that if there was a way to use EasyApache via shell I would then be able to select a more basic profile.

Via Google found this page:
How to manage Apache with Easyapache 4 on the command line? - YogSays - Technical Tips - Blogging

and while looking in /etc/cpanel/ea4/profiles I noticed there was a custom folder that contained the migrated EA3 to EA4 profile.
Therefore I tried to provision my custom profile but it failed due to lack of memory, so I stopped httpd then run the process to install the custom profile again, and this time it was able to run, remove all the extras and place me back where I started.

In case the site above disappears in the future, below is the command I used (except I referenced my custom migration profile).

#/usr/local/bin/ea_install_profile --install /etc/cpanel/ea4/profiles/cpanel/default.json

Rebooted the server and everything is back as it was, WHM is working and all the sites are working as well.
Definitely glad there is a shell way of doing things.

Thanks again for taking the time.
