Nginx 负载均衡 实战案例

实现效果
浏览器地址栏输入地址 http://172.31.0.99/oa/a.html，负载均衡效果，平均 8083 和 8084 端口中

一、配置

1、先创建2个文件夹，并将apache-tomcat-8.5.87解压到tomcat8083和tomcat8084中

（或者复制一份tomcat8081中的/apache-tomcat-8.5.87到这两个文件中）

typescript 复制代码 
[root@oa tools]# mkdir tomcat8083
[root@oa tools]# mkdir tomcat8084
typescript 复制代码 
[root@oa tools]# cp -r /tools/tomcat8081/apache-tomcat-8.5.87 tomcat8083
[root@oa tools]# cp -r /tools/tomcat8081/apache-tomcat-8.5.87 tomcat8084

2、修改Tomcat配置文件

tomcat8083

2、将tomcat8083中的server.xml内容修改后如下：

2.1、修改server 的默认端口，由默认8005->8093

2.2、修改http协议的默认端口，由默认的8080->8083

2.3修改默认ajp协议的默认端口，由默认的8009->9003

最终修改文件：

tomcat8084

tomcat4也是和tomcat3,修改相同的文职，变成不同的端口就行，可以看我最终修改的一下文件，就是修改成别的端口就行。

二、创建项目文件夹

tomcat8083

1、在/tools/tomcat8083/apache-tomcat-8.5.87/webapps，创建一个oa的文件夹

2、并在oa 的文件夹中，建立一个a.html文件，内容如下：

typescript 复制代码 
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
</head>
<body>
    <h1>NGINX 负载均衡Tomcat3</h1>
</body>
</html>

tomcat8084

1、在/tools/tomcat8084/apache-tomcat-8.5.87/webapps，创建一个oa的文件夹

2、并在oa 的文件夹中，建立一个a.html文件，内容如下：

typescript 复制代码 
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
</head>
<body>
    <h1>NGINX 负载均衡Tomcat4</h1>
</body>
</html>

三、启动Tomcatcat

1、启动tomcat8083

typescript 复制代码 
[root@oa tomcat8083]# cd /tools/tomcat8083/apache-tomcat-8.5.87/bin
[root@oa bin]# ./startup.sh

2、启动tomcat8084

root@oa tomcat8083\]# cd /tools/tomcat8084/apache-tomcat-8.5.87/bin \[root@oa bin\]# ./startup.sh ![在这里插入图片描述](https://file.jishuzhan.net/article/1726458294316306434/0a3b2663f386cd52ac12161204c36246.webp) ### 三、配置NGINX /usr/local/nginx/sbin
