实现效果
浏览器地址栏输入地址 http://172.31.0.99/oa/a.html负载均衡效果平均在 8083 和 8084 端口中刷新浏览器显示不同
一、配置
1、先创建2个文件夹tomcat8083和tomcat8084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
[rootoa tools]# mkdir tomcat8083
[rootoa tools]# mkdir tomcat8084[rootoa tools]# cp -r /tools/tomcat8081/apache-tomcat-8.5.87 tomcat8083
[rootoa tools]# cp -r /tools/tomcat8081/apache-tomcat-8.5.87 tomcat80842、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
!DOCTYPE html
html langen
headmeta charsetUTF-8meta nameviewport contentwidthdevice-width, initial-scale1.0titleDocument/title
/head
bodyh1NGINX 负载均衡Tomcat3/h1
/body
/htmltomcat8084
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
!DOCTYPE html
html langen
headmeta charsetUTF-8meta nameviewport contentwidthdevice-width, initial-scale1.0titleDocument/title
/head
bodyh1NGINX 负载均衡Tomcat4/h1
/body
/html三、启动Tomcatcat
1、启动tomcat8083
[rootoa tomcat8083]# cd /tools/tomcat8083/apache-tomcat-8.5.87/bin
[rootoa bin]# ./startup.sh 2、启动tomcat8084
[rootoa tomcat8083]# cd /tools/tomcat8084/apache-tomcat-8.5.87/bin [rootoa bin]# ./startup.sh 三、配置NGINX
1、找到NGINX的配置文件/usr/local/nginx/conf 路劲 下修改nginx.conf文件 2、进行负载均衡的配置 #user nobody;
worker_processes 1;#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;#pid logs/nginx.pid;events {worker_connections 1024;

3、启动nginx [rootoa bin]# cd /usr/local/nginx/sbin [rootoa sbin]# ./nginx 三、最终测试
访问http://172.31.0.99/oa/a.html
1、第一次访问 2、直接在浏览器中右击“”“重新加载”就看到如下的界面
