一、动静分离

1.单台机器动静分离

 [root@web01 ~]# cat /etc/nginx/conf.d/linux.wp.com.conf 
server {
    listen 80;
    server_name linux.wp.com;
 
    location / {
        root /code/wordpress;
        index index.php;
    }
 
    location ~* \.(jpg|png|gif)$ {
        root /code/wordpress;
    }
 
    location ~* \.php$ {
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_param SCRIPT_FILENAME /code/wordpress/$fastcgi_script_name;
        include fastcgi_params;
    }
}

2.多台机器的动静分离

1）准备环境

主机	作用	服务	IP	PORT
lb01	负载均衡	nginx	192.168.71.116	9090
web01	静态资源	nginx	192.168.71.112	8080
web02	静态资源	nginx	192.168.71.113	8080
web03	动态资源	tomcat	192.168.71.114	8080

2）配置web01的静态资源

 1、准备包
[root@web01 /usr/share/nginx/html]# cd /usr/share/nginx/html
[root@web01 /usr/share/nginx/html]# git clone https://gitee.com/egonlin/jsp_pro.git
[root@web01 /usr/share/nginx/html]# ll jsp_pro/
drwxr-xr-x 2 root root 27 6月   3 17:10 backend_code
drwxr-xr-x 4 root root 51 6月   3 17:10 frontend_code
 
2、修改配置文件
[root@web01 /usr/share/nginx/html]# cat /etc/nginx/conf.d/default.conf 
server {
    listen 8080;
    location / {
       root /usr/share/nginx/html/jsp_pro/frontend_code;
       index index.html;
    }
}
 
3、 启动服务
[root@web01 /usr/share/nginx/html]# systemctl restart nginx
 
4、测试访问
[root@web01 /usr/share/nginx/html]# curl -I 127.0.0.1:8080/index.html
HTTP/1.1 200 OK
Server: nginx/1.26.1
Date: Mon, 03 Jun 2024 09:19:37 GMT
Content-Type: text/html
Content-Length: 1061
Last-Modified: Mon, 03 Jun 2024 09:10:29 GMT
Connection: keep-alive
ETag: "665d8885-425"
Accept-Ranges: bytes

3）配置web02的动态资源

  
1、准备包
同上
 
2、修改配置文件
[root@web02 /usr/share/nginx/html]# cat /etc/nginx/conf.d/default.conf 
server {
    listen 8080;
 
    #location /static {
    location ~* \.(css|js|jpg|png|mp4|gif)$ {
       root /usr/share/nginx/html/jsp_pro/frontend_code;
    }
}
 
3、 启动服务
[root@web01 /usr/share/nginx/html]# systemctl restart nginx
 
4、测试访问
[root@web02 /usr/share/nginx/html]# curl -I 127.0.0.1:8080/static/css/a.css
HTTP/1.1 200 OK
Server: nginx/1.26.1
Date: Mon, 03 Jun 2024 09:17:02 GMT
Content-Type: text/css
Content-Length: 300
Last-Modified: Mon, 03 Jun 2024 09:10:29 GMT
Connection: keep-alive
ETag: "665d8885-12c"
Accept-Ranges: bytes
 
[root@web02 /usr/share/nginx/html]# curl -I 127.0.0.1:8080/static/img/1.jpg
HTTP/1.1 200 OK
Server: nginx/1.26.1
Date: Mon, 03 Jun 2024 09:17:13 GMT
Content-Type: image/jpeg
Content-Length: 950756
Last-Modified: Mon, 03 Jun 2024 09:10:29 GMT
Connection: keep-alive
ETag: "665d8885-e81e4"
Accept-Ranges: bytes

4）配置web03

 1、安装tomcat
yum install tomcat -y
 
2、准备包
[root@web03 ~]# git clone https://gitee.com/egonlin/jsp_pro.git
[root@web03 ~]# cp jsp_pro/backend_code/java_test.jsp /var/lib/tomcat/webapps/ROOT/
 
3、修改配置文件
无需修改
 
4、 启动服务
[root@web03 ~]# systemctl restart tomcat
 
5、测试访问
[root@web03 ~]# curl 127.0.0.1:8080/java_test.jsp
    
    
        随机数:137

5）配置负载均衡

  
1.配置
[root@lb01 ~]# cat /etc/nginx/nginx.conf 
 
user  nginx;
worker_processes  auto;
 
error_log  /var/log/nginx/error.log notice;
pid        /var/run/nginx.pid;
 
 
events {
    worker_connections  1024;
}
 
http {
    upstream frontend_server {
      server 192.168.71.112:8080 max_fails=3 fail_timeout=5s;
    }
    upstream file_server {
      server 192.168.71.113:8080 max_fails=3 fail_timeout=5s;
    }
    upstream backend_server {
      server 192.168.71.114:8080 max_fails=3 fail_timeout=5s;
    }
 
    server {
        listen       9090;
 
        location / {
           proxy_pass  http://frontend_server;
        }
 
        location ~* \.(css|js|jpg|png|gif)$ {
           proxy_pass  http://file_server;
        }
 
        location ~* \.jsp$ {
            proxy_pass http://backend_server;
        }
    }
}
 
 
2.重启
[root@lb01 ~]# systemctl restart nginx
