Running Nginx as non root user

Question

I installed Nginx using Ansible. To install on Centos7 I used the yum package so it by default was run as root user. I want it to start and run as a different user

Answer 1

Add/Change the following in your /etc/nginx/nginx.conf:

user nginx;

You should create the user and grant permissions on the webroot directories recursively.

This way only master process runs as root. Because: Only root processes can listen to ports below 1024. A webserver typically runs at port 80 and/or 443. That means it needs to be started as root.

To run master process as non root user:

Change the ownership of the following:

• error_log
• access_log
• pid
• client_body_temp_path
• fastcgi_temp_path
• proxy_temp_path
• scgi_temp_path
• uwsgi_temp_path

Change the listen directives to ports above 1024, log in as desired user and run nginx by nginx -c /path/to/nginx.conf
