How to install nginx and port configuration in CentOS

Find the supported information on the official nginx website:

Currently, nginx packages are available for the following distributions and versions:

RHEL/CentOS:

Version	Supported Platforms
5.x	X86_64, i386
6.x	X86_64, i386
7. x	X86_64

Debian:

Version	Codename	Supported Platforms
6.x	Squeeze	X86_64, i386
7. x	Wheezy	X86_64, i386
8. x	Jessie	X86_64, i386

Ubuntu:

Version	Codename	Supported Platforms
10.04	Lucid	X86_64, i386
12.04	Precise	X86_64, i386
14.04	Trusty	X86_64, i386, aarch64/arm64
14.10	Utopic	X86_64, i386

SLES:

To enable automatic update of Linux packages set up the yum repository for the RHEL/CentOS distributions, the apt repository for the Debian/Ubuntu distributions, or the zypper repository for SLES.

We can see that CentOS is installed through yum. Run the following command:

# Rpm-ivh http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm
 
# Yum-y install nginx
The installation is successful, and then the service is enabled, and a port conflict is reported. (Because apache is installed with Port 80 in advance)

# Service nginx start

Starting nginx: [emerg] bind () to 0.0.0.0: 80 failed (98: Address already in use)
Nginx: [emerg] bind () to 0.0.0.0: 80 failed (98: Address already in use)
Nginx: [emerg] bind () to 0.0.0.0: 80 failed (98: Address already in use)
Nginx: [emerg] bind () to 0.0.0.0: 80 failed (98: Address already in use)
Nginx: [emerg] bind () to 0.0.0.0: 80 failed (98: Address already in use)
Nginx: [emerg] still cocould not bind ()
[FAILED]

Find the nginx configuration file.

# Vim/etc/nginx. conf

There is a "include/etc/nginx/conf. d/*. conf;", and the file/etc/nginx/conf. d/default. conf is found again.

Vim/etc/nginx/conf. d/default. conf

Change listen 80 to listen 8080, and then start nginx.

1
# Service nginx restart
Open the browser and enter http: // localhost: 8080/. The following content is displayed.
