Installing and configuring the Nginx web server on Centos 6
How to install the Nginx using the Yum Command!
Recently i had install the Nginx Web server so i thought to share to share it with you all.
You can either download it to your repository and install it using rpm command or through the Yum install command its fairly depends on your infrastructure.
Now to lets take a Start.
Step #1 find the location of your repository to download the Rpm mine is located at the following location
# cd /var/ftp/pub/
Setp # 2 find out your operating system information using the command uname -a weather its 32bit or 64bit so that we can download the appropriate rpm for the repository.
# uname -a
output : Linux test.local 2.6.32-358.11.1.el6.x86_64 #1 SMP Wed Jun 12 03:34:52 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
if you see output as x86_64 then you can presume that you have 64bit os install on your server. or if you see i686 i386 then it an 32bit os install on your machine.
Setp # 3 Download and install RPM using the wget and RPM command
# wget http://nginx.org/packages/rhel/6/noarch/RPMS/nginx-release-rhel-6-0.el6.ngx.noarch.rpm
# rpm -ivh nginx-release-rhel-6-0.el6.ngx.noarch.rpm
