实现动静分离

实操环境

VMware软件
一台centos7作为nginx代理服务器。IP地址：192.168.20.40
一台centos7作为Tomcat1节点服务器。IP地址：192.168.20.10
一台centos7作为Tomcat2节点服务器。IP地址：192.168.20.20

实验目的

通过访问nginx代理服务器，静态自己处理，动态交给Tomcat处理

nginx 192.168.20.40
[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# hostnamectl set-hostname nginx
[root@localhost ~]# su
[root@nginx ~]# 

tomcat01 192.168.20.10
[root@localhost ~]# hostnamectl set-hostname tomcat01
[root@localhost ~]# su
[root@tomcat01 ~]#

tomcat02 192.168.20.20
[root@localhost ~]# hostnamectl set-hostname tomcat02
[root@localhost ~]# su
[root@tomcat02 ~]# 

iptables -F
setenforce 0
systemctl stop firewalld

负载均衡

实验环境

基于上一个实验环境

实验目的

通过访问nginx代理服务器，实现负载均衡

//Tomcat服务操作
tomcat01
[root@tomcat01 bin]# vim /usr/local/tomcat/webapps/test/index.jsp
<!DOCTYPE html>
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ page import="java.util.Date" %>
<%@ page import="java.text.SimpleDateFormat" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/ html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>动态页面</title>
</head>
<body>
<div>动态页面</div><br><img src="01.png"> //添加页面图片
</body>
</html>


//Nginx服务操作
[root@nginx conf]# vim /usr/local/nginx/conf/nginx.conf
        location ~.*\.(gif|jpg|jpeg|png|bmp|swf|css)$ {
    
    
            root html;
            expires 30d;
        }
(Tomcat指路径，Nginx放图片)
注意：目录名称需要和Java项目明后才能相同

[root@nginx conf]# mkdir /usr/local/nginx/html/test
[root@nginx conf]# cd /usr/local/nginx/html/test/
[root@nginx test]# rz -E
rz waiting to receive.
