HOW TO INSTALL NGINX SERVER IN REDHAT/CENTOS/FEDORA
HOW TO INSTALL NGINX SERVER IN REDHAT/CENTOS/FEDORA
Introduction
In this article we are going to learn How to install nginx server in Linux. Nginx Server stands for Engine-X is a Web Server like Apache Web Server but gives better performance as compared to Apache Web Server. nginx is an open source application can be used as proxy server for email services like Internet Mail Access Protocol (IMAP), Post Office Protocol (POP), Simple Mail Transfer Protocol (SMTP) and also can be used as caching server and supports Protocols like HTTP, TCP, UDP, SSL and so on. By Default the port number of Nginx Server is 80 but you can change it as per your need and requirement. Originally the NGINX was written by Igor Sysoev.
Follow the below steps to Install NGINX Server
First check the IP Address of your system using ifconfig command. Here my system’s IP Address is 192.168.0.103.
[root@localhost ~]# ifconfig eth0 # Checking the IP Address
eth0 Link encap:Ethernet HWaddr 00:0C:29:41:6A:AE
inet addr:192.168.0.103 Bcast:192.168.0.255 Mask:255.255.255.0

RX bytes:87195781 (83.1 MiB) TX bytes:2781470 (2.6 MiB)
Update your Packages and Repositories using below command.
Note : The update process will take some time to complete and this step is optional.
[root@localhost ~]# yum update # Update Packages & Repositories
Before we start the installation of NGINX Server we have to install some prerequisite packages required by NGINX. First we have to install epel-release package. EPEL stands for Extra Package for Enterprise Linux used to add some extra packages in redhat Linux repository which is by default not comes with operating system. So to install epel-release follow the below command.
[root@localhost ~]# yum -y install epel-release # Install epel-release Package
Loaded plugins: fastestmirror, refresh-packagekit, security
Loading mirror speeds from cached hostfile
* base: mirror.nbrc.ac.in
* extras: mirror.nbrc.ac.in
* updates: mirror.nbrc.ac.in

Now let’s go ahead and Install nginx server package using yum command. During Installation it will ask for y or n to continue the installation. so press enter y to continue the Installation.

To confirm installed packages you can use the rpm -qa command. refer the sample output below.
[root@localhost ~]# rpm -qa | grep nginx # Confirm the Installed Packages of nginx server
nginx-mod-mail-1.10.2-1.el6.x86_64
nginx-mod-http-image-filter-1.10.2-1.el6.x86_64

nginx-mod-stream-1.10.2-1.el6.x86_64

nginx-mod-http-perl-1.10.2-1.el6.x86_64
nginx-all-modules-1.10.2-1.el6.noarch
Once Installation completed we have to start the nginx server service but if you have already installed and using apache web server then you have to stop the apache service. we can’t use both web servers simultaneously as both web servers are using Port 80 as their default port.
So to stop the apache web server service you can use the below command.
[root@localhost ~]# /etc/init.d/httpd stop # Stop the Apache Web Server Service
Stopping httpd: [ OK ]
Once stopped the apache web server service you can now start the nginx server service using below command.
[root@localhost ~]# /etc/init.d/nginx start # Start the nginx Server Service
Starting nginx: [ OK ]
As you can see above currently my nginx server service is started. Let’s try to start the apache server service, let’s see what would be the output.
As you can see below I am getting below error message that Port 80 is already in use.
[root@localhost ~]# /etc/init.d/httpd start
Starting httpd: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain for ServerName
(98)Address already in use: make_sock: could not bind to address [::]:80
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs
[FAILED]
Start the nginx service at startup.
[root@localhost ~]# chkconfig --level 35 nginx on # Start the nginx server service at startup
You can confirm the startup enabled status using below command.
[root@localhost ~]# chkconfig --list nginx nginx 0:off 1:off 2:off 3:on 4:off 5:on 6:off
You can confirm. nginx currently Listening to which port by using netstat command. For that first check the status of the nginx server service using below command. Here you will get Process ID of nginx.
[root@localhost ~]# /etc/init.d/nginx status # Check the Status of nginx server nginx (pid 21312) is running...
Then you can check the nginx server Listen port by using service name or by Process ID (PID) number.
Check by using Service Name :
[root@localhost ~]# netstat -tulpn | grep nginx tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 21312/nginx tcp 0 0 :::80 :::* LISTEN 21312/nginx
Check by using Process ID (PID) Number :
[root@localhost ~]# netstat -tulpn | grep 21312 tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 21312/nginx tcp 0 0 :::80 :::* LISTEN 21312/nginx
Now you can check the default page of nginx server by using http://localhost OR http://YOUR_IP_ADDRESS
