9 nginx代理实践

1、服务器准备

主机	ip	身份
lb01	192.168.15.5	负载均衡
web01	192.168.15.7	web服务器
web02	192.168.15.8	web服务器
db01	192.168.15.51	数据库

2、web02配置

 

3、lb01服务器配置(使用七层负载均衡)

1.安装nginx

yum install nginx -y

2.简化nginx.conf文件

vi /etc/nginx/nginx.conf

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
events {
    worker_connections 1024;
}

http {
    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;
    tcp_nodelay         on;
    keepalive_timeout   65;
    types_hash_max_size 4096;

    include             /etc/nginx/mime.types;
    default_type        application/octet-stream;

    # Load modular configuration files from the /etc/nginx/conf.d directory.
    # See http://nginx.org/en/docs/ngx_core_module.html#include
    # for more information.
    include /etc/nginx/conf.d/*.conf;

}

3.创建一个IP连接池

cd /etc/nginx/conf.d

vim game.conf

upstream game {
    server 172.16.1.8:80;
}

server {
    server_name game1.test.com;
    listen 80;

    location / {
      proxy_pass http://game;
}
}

4.启动nginx

systemctl start nginx

5.修改Windows的host文件

192.168.15.5 game1.test.com

6.测试

http://game1.test.com

4、web01服务器配置

1.进入/etc/nginx/conf.d

2.把web02的配置和项目传到web01

cd /etc/nginx/conf.d
scp game1.conf 172.16.1.7:/etc/nginx/conf.d/
cd /usr/share/nginx
scp -r html5-mario 172.16.1.7:/usr/share/nginx/

3.web01服务器开启nginx

systemctl start nginx

4.测试

http://192.168.15.7/

5.修改lb01服务器

vim /etc/nginx/conf.d/game.conf

upstream game {
    server 172.16.1.8:80;
    server 172.16.1.7:80;
}

server {
    server_name game1.test.com;
    listen 80;

    location / {
      proxy_pass http://game;
}
}

然后重启lb01服务器的nginx

systemctl restart nginx

6.查看负载到那个服务器了

tail -f /var/log/nginx/access.log 

 

5、代理python项目

1.web02

cd /etc/nginx/conf.d
scp bbs1.conf 172.16.1.7:/etc/nginx/conf.d/
cd /opt
scp -r BBS18_day01 172.16.1.7:/opt

重启web02的nginx

systemctl restart nginx

2.web01配置参考如下：

3.lb01配置

upstream bbs {
    server 172.16.1.8:80;
    server 172.16.1.7:80;
}

server {
    server_name bbs1.test.com;
    listen 80;

    location / {
      proxy_pass http://bbs;
}
}

4.配置windows的hosts

5.测试

 

 

知识储备：

1.创建一个IP连接池（存放web服务器的IP的）

upstream
只能配置在：http

格式：

upstream [连接池的名称] {
    [存放的IP]
    server [ip1];
    server [ip2];
}

2.往IP连接池中丢请求

proxy_pass http://[连接池的名称];

 

重点！！！

nginx 指向同一个网站时：

一定要在最前面加

server {
listen 80 ;
server_name _;
return 403;
}
