### 1、什么是nginx？ ###

Nginx (engine x) 是一个高性能的HTTP和反向代理web服务器，同时也提供了IMAP/POP3/SMTP服务。如图，nginx常被用于做代理

### 2、 安装环境准备 ###

*  XFTP（linux文件上传）
 *  XShell（Linux远程软件）
 *  nginx-1.11.4（nginx linux版本）

### 3、安装部署Nginx ###

nginx安装之前要先安装pcre、openssl、zlib

> 注意：./configure --prefix=/usr/local/keepalived configure:error:!!!  
> OpenSSL is not properly installed on your system. !!! !!! Can not  
> include OpenSSL headers files.  
> 解决方法：安装openssl，同时pcre也一起安装一下，gcc、zlib没有安装也可以安装一下

yum -y install pcre pcre-devel openssl openssl-devel zlib* gcc

[nginx官网][nginx]下载nginx，解压到/usr/local/src

tar -xzvf nginx-1.11.4.tar.gz

cd nginx-1.11.4

执行配置文件

./configure

编译

make && make install

启动

cd /usr/local/nginx/sbin

./nginx

重启

cd /usr/local/nginx/sbin

./nginx -s reload

检验配置文件是否正确  
检验：

ps -ef|grep nginx

/usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf

或者

cd /usr/local/nginx/sbin

./nginx -t

查看nginx版本信息

nginx -V

### 4、Nginx负载均衡 ###

cd /usr/local/nginx/conf，找到nginx.conf配置文件  
在http\{\}里面加入,ip1就是你的一台服务器的ip，ip2同理

upstream  mynginxserver{
    server ip1:8080 weight=1 max_fails=1 fail_timeout=10s;
    server ip2:8081 weight=2 max_fails=1 fail_timeout=10s;
    }

upstream可以自己定义名称

然后再http\{\}的server\{\}里修改，加入proxy\_pass

location / {
            proxy_pass http://mynginxserver;
                root   html;
                index  index.html index.htm index.jsp;
            }

然后重启nginx

cd /usr/local/nginx/sbin
    ./nginx -s reload

### 5、keepalived安装 ###

下载keepalived到/usr/local/src

tar -xzvf keepalived-1.2.19.tar.gz
    cd /usr/local/src/keepalived-1.2.19

配置

./configure --prefix=/usr/local/keepalived

编译

make && make install

复制建立服务启动脚本，以便使用service命令控制之：

cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/rc.d/init.d/

chmod +x /etc/init.d/keepalived

cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/

mkdir /etc/keepalived

cp /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/

cp /usr/local/keepalived/sbin/keepalived /usr/sbin/

启动keepalived

service keepalived start|stop

详细使用可以参考[nginx官方文档][nginx 1]
