This tutorial is intended for those who want to install and configure phpPgAdmin manually so it can work with Nginx, without needing Apache. I created this tutorial using Ubuntu server 14.04.
Download phpPgAdmin
Download one of the compressed files at http://phppgadmin.sourceforge.net.
Extract files
Extract the compressed file to the folder you want to serve phpPgAdmin (example: /var/www/yoursite/phppgadmin)
Install PostgreSQL module for PHP
sudo apt-get install php5-pgsql
Create PostgreSQL superuser to use in phpPgAdmin
Choose a username for your superuser. Here I used (adminusername) and you can replace it for another username you prefer.
sudo su - postgres createuser --superuser --pwprompt adminusername
Enter the password for superuser.
Configure phpPgAdmin
Open the file phppgadmin/conf/config.inc.php (example: /var/www/yoursite/phppgadmin/conf/config.inc.php)
If Postgres and phpPgAdmin is installed in the same server, change the line:
$conf['servers'][0]['host'] = 'localhost';
Search the file for extra_login_security. If extra_login_security = true, login attempts on phpPgAdmin with no password or certain usernames (pgsql, postgres, root, administrator) will be denied (you will get the “Login disallowed for security reasons.” error). So, set extra_login_security to false if it is your case.
$conf['extra_login_security'] = false;
Nginx virtual host
If your site is already served with Nginx, just access http://yoursite.com/phppgadmin
But If you want to access phpPgAdmin from another URL like a subdomain for example, a Nginx virtual host file for phpPgAdmin is needed.
This is just a sample of a Nginx virtual host file:
server { server_name phpmyadmin.yoursite.com; index index.html index.htm index.php; root /var/www/yoursite/phppgadmin; access_log off; location ~ \.php$ { try_files $uri =404; fastcgi_split_path_info ^(.+\.php)(/.+)$; fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_index index.php; include fastcgi_params; } }
