Install PostgreSQL Nginx phpPGadmin at Centos7

2 minute read

My note about installing PostgreSQL, NGINX, and phpPGadmin at Centos7

NGINX section

At this phase, we will install the NGINX web server at centos7. To installing NGINX at centos7, first we need to add epel repository.

yum install epel-repo

After epel repository installed now we can install NGINX

yum install nginx

Start NGINX

systemct  start nginx

Allow HTTP and HTTPS port in firewall

sudo firewall-cmd --permanent --zone=public --add-service=http
sudo firewall-cmd --permanent --zone=public --add-service=https
sudo firewall-cmd --reload

Now check access of webserver

http://your_ip_adress

PHP section

We are add PHP function at this step,

yum install php php-mysql php-fpm

Configure php processor, edit the php-fpm configuration /etc/php.ini. Specially for cgi.fix_pathinfo we had to commenting out and set the value to 0.

cgi.fix_pathinfo=0

open the php-fpm configuration file /etc/php-fpm.d/www.conf find the listen, listen.owner, listen.group, user, and group section, and make it look like this :

listen = /var/run/php-fpm/php-fpm.sock

listen.owner = nobody
listen.group = nobody

user = nginx
group = nginx

Start php processor, and enabled it:

systemctl start php-fpm
systemctl enable php-fpm

Next, we had to configure nginx for handling the PHP process. Create the default NGINX server block configuration file /etc/nginx/conf.d/default.conf , create configuration looks like :

server {
    listen       80;
    server_name  server_domain_name_or_IP;

    # note that these lines are originally from the "location /" block
    root   /usr/share/nginx/html;
    index index.php index.html index.htm;

    location / {
        try_files $uri $uri/ =404;
    }
    error_page 404 /404.html;
    error_page 500 502 503 504 /50x.html;
    location = /50x.html {
        root /usr/share/nginx/html;
    }

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}

then restart NGINX, systemctl restart nginx

PostgreSQL section

Now installing database, we are gonna installing PostgreSQL at this step.

yum install postgresql-server postgresql-contrib

Create a new database cluster

postgresql-setup initdb

editing /var/lib/pgsql/data/pg_hba.conf to make PostgreSQL to support password authentication based, make config like this :

host    all             all             127.0.0.1/32            md5
host    all             all             ::1/128                 md5

start and enable PostgreSQL,

systemctl start postgresql
systemctl enable postgresql

Login as PostgreSQL user, and create PostgreSQL role (user)

sudo su postgres
createuser -P --interactive
postgres@your_machine_name:~$ createuser -P --interactive
Enter name of role to add: test
Enter password for new role:
Enter it again:
Shall the new role be a superuser? (y/n) n
Shall the new role be allowed to create databases? (y/n) y
Shall the new role be allowed to create more new roles? (y/n) n
postgres@your_machine_name:~$

so the user create was test

phpPGadmin section

Relax security, add firewall exception

firewall-cmd --zone=public --permanent --add-service=http
firewall-cmd --zone=public --permanent --add-port=5432/tcp
firewall-cmd --reload

also relax selinux

setsebool -P httpd_can_network_connect on
setsebool -P httpd_can_network_connect_db on

Setup PostgreSQL listening address, by editing /var/lib/pgsql/data/postgresql.conf file

listen_addresses = '*'
port = 5432

Install phpPGadmin,

yum install phpPgAdmin

Configure phpPGadmin, by created /etc/nginx/conf.d/phpPgAdmin.conf file ,

# Server block for phppgadmin service
server{
        server_name     YOUR_SERVER;
        root            /usr/share/phpPgAdmin;

        access_log      /var/log/phppgadmin/access.log;
        error_log       /var/log/phppgadmin/error.log;

        location ~ \.php$ {
                try_files $uri =404;
                fastcgi_split_path_info ^(.+\.php)(/.+)$;
                fastcgi_pass unix:/var/run/php5-fpm.sock;
                fastcgi_index index.php;
                fastcgi_param SCRIPT_FILENAME /path/to/your/www/postgres$fastcgi_script_name;
                include /etc/nginx/fastcgi_params;
        }
}

Edit phpPGadmin config file /etc/phpPgAdmin/config.inc.php

$conf['servers'][0]['host'] = 'localhost';

$conf['servers'][0]['port'] = 5432;

$conf['owned_only'] = true;

Restart all service

systemctl restart postgresql.service nginx.service php-fpm.service
