Nginx系列之Linux系统安装部署Nginx环境

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官网下载nginx，解压到/usr/local/src

tar -xzvf nginx-1.11.4.tar.gz

  
 

  
1
 

cd nginx-1.11.4

  
 

  
1
 

执行配置文件

./configure

  
 

  
1
 

编译

make && make install

  
 

  
1
 

启动

cd /usr/local/nginx/sbin

  
 

  
1
 

./nginx

  
 

  
1
 

重启

cd /usr/local/nginx/sbin

  
 

  
1
 

./nginx -s reload

  
 

  
1
 

检验配置文件是否正确
检验：

ps -ef|grep nginx

  
 

  
1
 

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

  
 

  
1
 

或者

cd /usr/local/nginx/sbin

  
 

  
1
 

./nginx -t

  
 

  
1
 

查看nginx版本信息

nginx -V

  
 

  
1
 

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;
}

  
 

  
1
  
2
  
3
  
4
 

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; }

  
 

  
1
  
2
  
3
  
4
  
5
 

然后重启nginx

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

  
 

  
1
  
2
 

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

  
 

  
1
  
2
 

配置

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

  
 

  
1
 

编译

make && make install

  
 

  
1
 

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/

  
 

  
1
 

chmod +x /etc/init.d/keepalived

  
 

  
1
 

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

  
 

  
1
 

mkdir /etc/keepalived

  
 

  
1
 

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

  
 

  
1
 

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

  
 

  
1
 

启动keepalived

service keepalived start|stop

  
 

  
1
 

详细使用可以参考nginx官方文档
