1. Nginx 是什么？

　　Nginx 是一款轻量级Web服务器，也是一款反向代理服务器

2. Nginx 能干什么

　　可以直接支持Rails 和PHP 程序

　　可以作为HTTP反向代理

　　作为负载均衡服务器

　　作为邮件代理服务器

　　帮助前端实现动静分离

3. Nginx 特点

　　高稳定

　　高性能

　　资源占用少

　　功能丰富

　　模块化结构

　　支持热部署

4. Nginx 安装

　　(1) 安装gcc (yum install gcc)

备注：可以输入gcc -v 查询版本信息，看系统是否自带安装

　　(2) 安装pcre (yum install pcre-devel)　

　　(3) 安装zlib (yum install zlib zlib-devel)

　　(4) 安装openssl (yum install openssh openssh-devel)

　　(5) 下载源码包，选择稳定版本（http://www.nginx.org/）　

wget http://nginx.org/download/nginx-1.10.2.tar.gz　

tar -zxvf nginx-1.10.2.tar.gz

　　(6) 进入nginx目录之后执行./configure

　　　　也可以指定安装目录，增加参数--prefix=/usr/nginx

　　　　如果不指定路径，可以通过whereis nginx进行查询

　　　　默认安装在/usr/local/nginx

　　(7) 　继续执行make

　　(8) 继续执行make install

5. nginx 常用命令

　　(1). 测试配置文件

　　　　安装目录下的/nginx/sbin/nginx -t

　　(2). 启动命令

　　　　安装路径下的/nginx/sbin/nginx

　　(3).停止命令

　　　　安装路径下的/nginx/sbin/nginx -s stop 或者 nginx -s quit

　　(4). 重启命令 

　　　　安装路径下的/nginx/sbin/nginx -s reload

　　(5). 查看进程命令

　　　　ps -ef | grep nginx

　　(6). 平滑重启

　　　　kill -HUP {Nginx 主进程号（既查看进程命令查到的PID）}

　　(7). 增加防火墙权限

sudo vi /etc/sysconfig/iptables

-A INPUT -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT

sudo service iptables restart

6. 虚拟域名配置及测试验证

　　（1）编辑sudo vi /usr/local/nginx/conf/nginx.conf

　　（2）增加include vhost/*.conf

}

　　（3）在/usr/local/nginx/conf/ 目录新建vhost文件夹,既：/usr/local/nginx/conf/vhost

　　（4）创建域名转发配置文件，点击查看详情

　　（5）启动（重启）验证

　　　　启动：${nginx}/sbin/nginx

　　　　重启：${nginx}/sbin/nginx -s reload

${nginx} 安装路径， /usr/local/nginx

　　（6）访问验证

　　　　使用默认80端口访问验证：http://localhost:80 或http://127.0.0.1:80 ,本次验证，我们使用的虚拟机因此http://172.31.8.112:80

　　

7. Nginx 虚拟域名配置

 

8. Nginx 本地搭建环境注意事项

（1). 可以配置域名转发，但是请注意要配置host，并且使host生效之后才可以，设置完成之后要重启浏览器

  (2). Linux

　　sudo vi /etc/hosts

　　添加好对应的域名及IP
