在nginx官网上找到支持信息：
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 updates 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.
看到是支持CentOS通过yum安装的，直接上命令：
# rpm -ivh http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm
# yum -y install nginx
就成功安装了，然后开启服务，报端口冲突。（由于事先安装了apache占用了80端口）
# service nginx start
Starting nginx: 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 could not bind()
[FAILED]
于是找到nginx的配置文件
# vim /etc/nginx/nginx.conf
看到里面有一句”include /etc/nginx/conf.d/*.conf;”，于是又找到/etc/nginx/conf.d/default.conf这个文件
vim /etc/nginx/conf.d/default.conf
打开后把listen 80改成listen 8080，然后启动nginx。
1
# service nginx restart
打开浏览器 输入http://localhost:8080/，就可以看到出现如下内容。
