Nginx反向代理负载均衡

web服务器与负载均衡服务器分别进行编译安装Nginx软件

mkdir -p /server/tool/
wget http://nginx.org/download/nginx-1.16.1.tar.gz /server/tool/

tar xf nginx-1. tar.gz　　　　解压软件
yum install -y pcre-devel openssl-devel　　安装相关依赖包
useradd -M -s /sbin/nologin www　　　　创建管理用户
cd /server/tool/nginx-1.16.1
./configure --prefix=/application/nginx-1.16 --user=www --group=www --with-http_ssl_module --with-http_stub_status_module
make && make install　　　　　　进行编译安装

[root@web03 ~]# /app/nginx/sbin/nginx -V　　查看之前编译安装方法
nginx version: nginx/1.16.1
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-18) (GCC)
built with OpenSSL 1.0.1e-fips 11 Feb 2013
TLS SNI support enabled
configure arguments: --prefix=/app/nginx-1.16.1 --user=www --group=www --with-http_ssl_module --with-http_stub_status_module

 创建nginx软链接

[root@web03 nginx-1.16.1]# ln -s /app/nginx-1.16.1/ /app/nginx
[root@web03 nginx-1.16.1]# cd /app/
[root@web03 app]# ll
total 4
lrwxrwxrwx. 1 root root 18 Aug 20 15:46 nginx -> /app/nginx-1.16.1/
drwxr-xr-x. 6 root root 4096 Aug 20 15:43 nginx-1.16.1

在web服务器 进行nginx服务测试是否启动运行是否正常

[root@web02 ~]# netstat -lntup |grep nginx
tcp        0      0 0.0.0.0:80                  0.0.0.0:*                   LISTEN      1191/nginx          

进入负载均衡服务器进行远程测试是否正常

[root@fz-05 conf]# curl  -H host:www.impkk.com 10.0.0.7/
10.0.0.7 www.impkk.com
[root@fz-05 conf]# curl  -H host:www.impkk.com 10.0.0.8/
10.0.0.8 www.impkk.com
[root@fz-05 conf]# curl  -H host:www.impkk.com 10.0.0.9/
(10.0.0.9) www.impkk.com

负载均衡服务器配置如下 （设置web服务区块并在location模块加加以调度）

[root@fz-05 conf]# cat nginx.conf
worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    upstream fz{
    server 10.0.0.7:80;
    server 10.0.0.9:80;
    server 10.0.0.8:80;
    }
    server {
        listen       80;
        server_name  localhost;
        root   html;
        index  index.html index.htm;
        location / {
        proxy_pass httpo://fz;
        } 
    }
    }

 进行测试

[root@fz-05 conf]# curl -H host:www.impkk.com 10.0.0.5/index.html
10.0.0.7 www.impkk.com
[root@fz-05 conf]# curl -H host:www.impkk.com 10.0.0.5/index.html
(10.0.0.9) www.impkk.com
[root@fz-05 conf]# curl -H host:www.impkk.com 10.0.0.5/index.html
10.0.0.8 www.impkk.com
