Install a LEMP Stack on CentOS 7

Here is a great tutorial for installing a LEMP stack on Linode


https://www.linode.com/docs/web-servers/lemp/lemp-stack-on-centos-7-with-fastcgi/


I did this on Centos 7 and it worked great.


Notes:

1. In your test.php file, remember to replace 

                   $username = "testuser";

                   $password = "password";

with the username and password you created to login to  MariaDB 

2. On Centos 7 you need to turn off SELinux or set it to permissive. Otherwise you'll get 'No Input file specified' when you test the web page

If /var/log/nginx/error.log has '[error] 20049#20049: *43 FastCGI sent in stderr: "Unable to open primary script: /var/www/<yourwebsite>.com/test.php (No such file or directory)"

Then you can temporarily set SELinux to permissive by running this command

[root@linuxhost~]# setenforce 0

Then run

[root@linuxhost~]# sestatus

Make sure it says 'Current mode: permissive'

Then test your website again.

To set SELinux back to enforcing , run [root@linuxhost~]# setenforce 1
