Nginx nginx: [warn] nginx was built without PCRE JIT support in /usr/local/nginx/conf/nginx.conf:8

Did you ever set NGINX_PCREJIT=n in persistent config file at /etc/centminmod/custom_config.inc as outlined at Upgrade Centmin Mod - CentminMod.com LEMP Nginx web stack for CentOS ? That will override NGINX_PCREJIT=y set in centmin.sh

 

did you recompile Nginx after NGINX_PCREJIT=y set in centmin.sh ? updating on Centmin Mod code itself isn't enough if you previously had NGINX_PCREJIT=n on a previous Nginx compile.

 

check your nginx upgrade log contents - you can find the actual log via command

list files in ascending date

Code:

ls -lAhrt /root/centminlogs

using Pastebin.com or Gists to share a sanitised version of the contents of the nginx upgrade log. You can see full details at How to troubleshoot Centmin Mod initial install issues
