第一种方法：通过配置EPEL源，然后通过yum安装Nginx服务 1、配置EPEL源，我这边以阿里云镜像为例（http://mirrors.aliyun.com/） [root@static ~]# cd /etc/yum.repos.d/ [root@static yum.repos.d]# ll total 24 -rw-r--r--. 1 root root 1991 Dec 1 16:16 CentOS-Base.repo -rw-r--r--. 1 root root 647 Dec 1 16:16 CentOS-Debuginfo.repo -rw-r--r--. 1 root root 289 Dec 1 16:16 CentOS-fasttrack.repo -rw-r--r--. 1 root root 630 Dec 1 16:16 CentOS-Media.repo -rw-r--r--. 1 root root 6259 Dec 1 16:16 CentOS-Vault.repo [root@static yum.repos.d]# wget -O /etc/yum.repos.d/epel-6.repo http://mirrors.aliyun.com/repo/epel-6.repo --2017-12-01 16:17:36-- http://mirrors.aliyun.com/repo/epel-6.repo Resolving mirrors.aliyun.com... 180.163.159.87, 180.163.159.88, 180.163.159.100, ...

SELINUX=disabled # SELINUXTYPE= can take one of these two values: # targeted - Targeted processes are protected, # mls - Multi Level Security protection. SELINUXTYPE=targeted 测试访问如下  第二种： 通过nginx yum repository安装最新版本的nginx 1、配置yum源 [root@static ~]# vim /etc/yum.repos.d/nginx.repo [nginx] name=nginx repo baseurl=http://nginx.org/packages/centos/6/$basearch/ gpgcheck=0 enabled=1 注意： baseurl=http://nginx.org/packages/OS/OSRELEASE/$basearch/ Replace “OS” with “rhel” or “centos”, depending on the distribution used, and “OSRELEASE” with “6” or “7”, for 6.x or 7.x versions, respectively. 2、查看nginx版本 [root@static ~]# yum info nginx  3、安装nginx [root@static ~]# yum -y install nginx 4、Nginx的目录结构 配置文件： /etc/nginx 日志文件： /var/log/nginx 默认主目录： /usr/share/nginx/html 模块目录： /usr/lib64/nginx/modules 启动脚本：/etc/rc.d/init.d/nginx 说明文档目录： /usr/share/doc/ 5、启动nginx服务 [root@static nginx]# service nginx start Starting nginx: [ OK ] [root@static nginx]# ss -tunlp|grep nginx tcp LISTEN 0 128 *:80 *:* users:(("nginx",1476,6),("nginx",1478,6))
