@brucehu said in Fog1.5.9, the php-fpm.service service exited abnormally and could not be started:

After compiling and installing php7.2.3 and pre installing PHP FPM

What exactly do you mean by that? Please give us more details on what commands you used.

There is no need to compile or manually install things beforehand. A plain CentOS install will do. Then run the FOG installer. The more you try to customize things (like compile and install things manually) the more issues you run into!

I just did a fresh FOG 1.5.9 install on a clean new CentOS Linux release 7.9.2009 setup. Worked perfectly fine. No issues.
