二、基础环境
hostnamectl set-hostname tomcat1
hostnamectl set-hostname tomcat2
hostnamectl set-hostname nginx三、安装配置Tomcat
1.安装依赖
dnf -y install tar
rpm -ivh jdk-8u102-linux-x64.rpm2.解压并安装
tar xf apache-tomcat-9.0.8.tar.gz
mv apache-tomcat-9.0.8/ /usr/local/tomcat93.启动Tomcat
/usr/local/tomcat9/bin/startup.sh4.访问测试
http://192.168.16.142:8080/
http://192.168.16.143:8080/
5.创建存放网页的文件
mkdir -pv /web/webapp16.建立网页测试文件
vi /web/webapp1/index.jsp<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <html>
<head>
<title>JSP test2 page</title> </head>
<body>
<% out.println("动态页面 2,http://www.test2.com") ;%> </body>
<body>
<div>动态页面的图片 2</div><br><img src="logo.png">
</body>
</html>7.修改Tomcat的server.xml文件（162行后添加）
vi /usr/local/tomcat9/conf/server.xml<Context docBase="/web/webapp1" path="" reloadable="false" ></Context>8.重启Tomcat
/usr/local/tomcat9/bin/shutdown.sh
/usr/local/tomcat9/bin/startup.sh四、安装配置Nginx
1.安装Nginx
dnf install -y gcc make pcre-devel zlib-devel openssl-devel perl-ExtUtils-MakeMaker tar
useradd -M -s /sbin/nologin nginx
tar zxf nginx-1.26.3.tar.gz
cd nginx-1.26.3
./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_ssl_module --with-http_v2_module --with-pcre
make && make install2.配置Nginx.conf
vi /usr/local/nginx/conf/nginx.conf#（33行下添加）
upstream tomcat_server {server 192.168.16.142:8080 weight=1;server 192.168.16.143:8080 weight=1;}# 动态页面正则（48行下添加）
location ~ .*.jsp$ {
proxy_set_header HOST $host;proxy_set_header X-Real-IP $remote_addr;proxy_set_header Client-IP $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;proxy_pass http://tomcat_server;}# 静态图片正则
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$ { root /usr/local/nginx/html/img;expires 30d;}3.创建静态文件目录并上传图片
mkdir /usr/local/nginx/html/img
mv /root/logo.png /usr/local/nginx/html/img/
ls /usr/local/nginx/html/img
logo.png4.添加网页测试文件
vi /usr/local/nginx/html/index.html<!DOCTYPE html><html><head><meta http-equiv="content-type" content="text/html;charset=utf-8"><title>静态页面</title><style>body {width: 35em;margin: 0 auto;
font-family: Tahoma, Verdana, Arial, sans-serif;}</style></head><body><h1>静态页面</h1><p>这是个静态页面</p></body></html>5.测试配置文件是否正确
/usr/local/nginx/sbin/nginx -t6.启动Nginx服务
/usr/local/nginx/sbin/nginx7.测试静态网页
8.测试负载均衡
a.更改tomcat1网页
vi /web/webapp1/index.jsp<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <html>
<head>
<title>JSP test2 page</title> </head>
<body>
<% out.println("动态页面 1,http://www.test1.com") ;%> </body>
<body>
<div>动态页面的图片 2</div><br><img src="logo.png">
</body>
</html>b.测试
多次访问 http://192.168.16.144/index.jsp 应轮流显示来自tomcat1和tomcat2的响应
