Installing MEN NPP stack (MongoDB, Express, Node.js, Nginx, PostgreSQL, PHP) on CentOS 7 from scratch

I've been playing with my VPS that I bought from and I previously wrote about how to set up your VPS from scratch. Here I'll show just brief commands for installing a MEN NPP stack (MongoDB, Express, Node.js, Nginx, PostgreSQL, PHP) on my CentOS machine.


  • high performance web server that is much more flexible and lightweight than Apache
  • SELinux - if you run into issues change the SELinux mode to permissive or disabled
  • sudo rpm -Uvh
  • sudo yum install nginx
  • sudo systemctl start nginx.service or sudo service nginx start
  • sudo systemctl enable nginx.service (no alternative with sudo service)
  • default server root directory /usr/share/nginx/html defined /etc/nginx/conf.d/default.conf
  • server blocks (known as Virtual Hosts in Apache) are created in /etc/nginx/conf.d. Files that end with .conf in that directory will be loaded when Nginx is started
  • main Nginx configuration file is located at /etc/nginx/nginx.conf
  • sudo vi /etc/nginx/conf.d/default.conf looks like:
    server {
        listen       80;
        server_name  localhost;
        location / {
            root   /usr/share/nginx/html;
            index  index.html index.htm;
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   /usr/share/nginx/html;

    change to:

    server {
        listen       80;
        server_name  server_domain_name_or_IP;
        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;
  • sudo systemctl restart nginx
  • sudo nginx -t
    nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
    nginx: configuration file /etc/nginx/nginx.conf test is successful


  • just a side note for Mac: brew install node
  • sudo yum install epel-release
  • sudo yum install node
  • sudo yum install npm


  • npm install express


  • sudo yum install php php-mysql php-fpm
  • sudo vi /etc/php.ini - in order to secure it do cgi.fix_pathinfo=0
  • sudo vi /etc/php-fpm.d/www.conf set line to listen = /var/run/php-fpm/php-fpm.sock
  • sudo systemctl start php-fpm
  • sudo systemctl enable php-fpm.service to start from boot



  • exclude the CentOS version of postgres in order to get the most recent version from the project's website
  • sudo vim /etc/yum.repos.d/CentOS-Base.repo
    At the bottom of the [base] and [updates] sections, add a line that excludes the postgres packages: exclude=postgresql*
  • Find the link for your version of the OS here
  • curl -O
  • rpm -ivh pgdg*
  • yum list postgres*
  • install the -server package: sudo postgresql94-server.x86_64
  • sudo /usr/pgsql-9.4/bin/postgresql94-setup initdb
  • chkconfig postgresql-9.3 on
  • service postgresql-9.3 start
  • postgres creates a user and a database called postgres
  • sudo su - postgres
  • psql
  • \?: Get a full list of psql commands, including those not listed here
  • \h: Get help on SQL commands. You can follow this with a specific command to get help with the syntax
  • \q: Quit the psql program and exit to the Linux prompt
  • \d: List available tables, views, and sequences in current database
  • \du: List available roles
  • \dp: List access privileges
  • \dt: List tables
  • \l: List databases
  • \c: Connect to a different database. Follow this by the database name
  • \password: Change the password for the username that follows
  • \conninfo: Get information about the current database and connection
    CREATE TABLE new_table_name (
        table_column_title TYPE_OF_DATA column_constraints,
        next_column_title TYPE_OF_DATA column_constraints,
    ) INHERITS existing_table_to_inherit_from;



  • Instructions from here
  • sudo vim /etc/yum.repos.d/mongodb.repo:
    name=MongoDB Repository
  • sudo yum install -y mongodb-org
  • to prevent unintended upgrades, add to /etc/yum.conf file:
  • sudo service mongod start
  • sudo chkconfig mongod on
