Nginx 是一个很强大的高性能Web和反向代理服务器，它具有众多非常优越的特性。诸如低开销，高并发，支持缓存，支持正反向代理，支持负载均衡，支持正则，支持rewrite等等不一而足。所以众多粉丝们也是不计其数。本文基于CentOS 7简要描述yum方式的安装部署，供大家参考。

如果是编译安装可以参考：[Linux 6下安装编译安装Nginx][Linux 6_Nginx]  
有关Nginx的常用配置可参考：[Nginx 概述及日常管理][Nginx]

## 一、配置nginx yum源 ##

演示环境
    [root@centos7-router ~]# more /etc/redhat-release
    CentOS Linux release 7.2.1511 (Core)
    
    [root@centos7-router ~]# vim /etc/yum.repos.d/nginx.repo
    
    [nginx]
    name=nginx repo
    baseurl=http://nginx.org/packages/OS/OSRELEASE/$basearch/
    gpgcheck=0
    enabled=1
    
    将上述配置文件中的OS替换为rhel或者centos，OSRELEASE替换为6或者7，即当前的Linux为6还是7版本
    
    查看本机ip
    [root@centos7-router ~]# ip addr|grep inet|grep global
    inet 172.24.8.254/24 brd 172.24.8.255 scope global eno16777728
    inet 192.168.1.175/24 brd 192.168.1.255 scope global dynamic eno33554960

## 二、安装nginx ##

[root@centos7-router ~]# yum install nginx -y
    [root@centos7-router ~]# yum install nginx-module-perl.x86_64 -y 
    
    查看生程的相关文件
    [root@centos7-router ~]# rpm -ql nginx
    /etc/logrotate.d/nginx
    /etc/nginx
    /etc/nginx/conf.d
    /etc/nginx/conf.d/default.conf
    /etc/nginx/fastcgi_params
    /etc/nginx/koi-utf
    /etc/nginx/koi-win
    /etc/nginx/mime.types
    /etc/nginx/modules
    /etc/nginx/nginx.conf
    /etc/nginx/scgi_params
    /etc/nginx/uwsgi_params
    /etc/nginx/win-utf
    /etc/sysconfig/nginx
    /etc/sysconfig/nginx-debug
    /usr/lib/systemd/system/nginx-debug.service
    /usr/lib/systemd/system/nginx.service
    /usr/lib64/nginx
    /usr/lib64/nginx/modules
    /usr/libexec/initscripts/legacy-actions/nginx
    /usr/libexec/initscripts/legacy-actions/nginx/check-reload
    /usr/libexec/initscripts/legacy-actions/nginx/upgrade
    /usr/sbin/nginx
    /usr/sbin/nginx-debug
    /usr/share/doc/nginx-1.12.2
    /usr/share/doc/nginx-1.12.2/COPYRIGHT
    /usr/share/man/man8/nginx.8.gz
    /usr/share/nginx
    /usr/share/nginx/html
    /usr/share/nginx/html/50x.html
    /usr/share/nginx/html/index.html
    /var/cache/nginx
    /var/log/nginx

## 三、验证nginx ##

启动nginx
    root@centos7-router ~]# systemctl start nginx
    [root@centos7-router ~]# systemctl enable nginx    ###配置自启动
    [root@centos7-router ~]# ss -nltp|grep nginx
    LISTEN 0 128 *:80 *:* users:(("nginx",pid=65418,fd=6),("nginx",pid=65415,fd=6))
    
    查看nginx的版本
    [root@centos7-router ~]# nginx -v
    nginx version: nginx/1.12.2
    
    查看或修改配置文件
    [root@centos7-router ~]# more /etc/nginx/nginx.conf
    
    user nginx;
    worker_processes 1;
    
    error_log /var/log/nginx/error.log warn;
    pid /var/run/nginx.pid;
    
    events {
    worker_connections 1024;
    }
    
    http {
    include /etc/nginx/mime.types;            ### Author : Leshami
    default_type application/octet-stream;  ### Blog : http://blog.csdn.net/leshami
    
    log_format main '$remote_addr - $remote_user [$time_local] "$request" '
    '$status $body_bytes_sent "$http_referer" '
    '"$http_user_agent" "$http_x_forwarded_for"';
    
    access_log /var/log/nginx/access.log main;
    
    sendfile on;
    #tcp_nopush on;
    
    keepalive_timeout 65;
    
    #gzip on;
    
    include /etc/nginx/conf.d/*.conf;
    }
    
    [root@centos7-router ~]# firewall-cmd --add-service=http --permanent
    [root@centos7-router ~]# firewall-cmd --reload
    
    从其他机器验证nginx
    [root@centos7-web ~]# curl http://172.24.8.254
    <!DOCTYPE html>
