Ubuntu
Nginx is available with default Ubuntu Repositories. So simple install it using the following command,
$ sudo apt-get update && sudo apt-get install nginx
CentOS/RHEL
Since Nginx is available with default RHEL/CentOS repositories, we either need to enable official Nginx repository or Epel repository
Nginx Repository
To enable Nginx repository, create a file named ‘nginx.repo’ in ‘/etc/yum.repos.d’ & add the following repo information
$ vi /etc/yum.repos.d/nginx.repo
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/OS/OSRELEASE/$basearch/
gpgcheck=0
enabled=1
Replace “OS” with “rhel” or “centos”, depending on the distribution used, and “OSRELEASE” with “5”, “6”, or “7”, for 5.x, 6.x, or 7.x versions, respectively.
Epel Repository
RHEL/CentOS 7
$ rpm -Uvh https://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/e/epel-release-7-11.noarch.rpm
RHEL/CentOS 6 (64 Bit)
$ rpm -Uvh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
RHEL/CentOS 6 (32 Bit)
$ rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
Install Nginx server
Once the Nginx/Epel repository has been enabled, installation can be easily done with yum. To install nginx server, run
$ yum install nginx
Now start the nginx service & also enable it after reboot,
$ systemctl start nginx
$ systemctl enable nginx
