I was able to do the following and get WP to work. I assume it will be reset if I need to restart the server but its fairly easy to repeat.
in SSH, edit the php-fpm.config file so the last line is “php_admin_value[memory_limit] = 64M” so that it is 64M or higher. (Default is 8M):
~ # cd /etc/php
/etc/php # vi php-fpm.comf
when you finish editing hit (esc) and then type " : " (colon). This should bring up a prompt at the bottom. Type wq and hit enter. This will save the edit and get you back to ssh prompt.
from here type “killall php-fpm”
give it a few minutes… maybe try to log into phpmyadmin to see if it makes a connection. If it doesn’t type:
“mysql -u admin -p”
input the password and mysql should start up. From here Word Press should work perfectly.
Enjoy!
