动静分离：

访问静态和动态页面分开

实现动态和静态页面负载均衡

实验1：

准备三台虚拟机：

1台nginx代理服务器：

192.168.120.30

2台tomcat：

tomcat1：192.168.120.20

tomcat2：192.168.120.50

同时关闭防火墙和安全机制

进入代理服务器

vim /usr/local/nginx/conf/nginx.conf

upstream tomcat {

        server 20.0.0.25:8080 weight=1;

        server 20.0.0.26:8080 weight=2;

}

location ~* \.jsp$ {

proxy_pass http://tomcat;

proxy_set_header HOST $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

}

nginx -t

#检测一下

systemctl restart nginx

vim /usr/local/nginx/html/index.html

配置动态页面

进入tomcat1和tomcat2

vim /usr/local/tomcat/conf/server.xml

148行删除

添加

mkdir /usr/local/tomcat/webapps/test

vim /usr/local/tomcat/webapps/test/index.jsp

tomcat1：

tomcat2：

./shutdown.sh 关闭

./startup.sh   开启

实验2：

四层+七层+动静分离

192.168.120.30nginx1代理服务器

192.168.120.40 nginx七层代理

192.168.120.60 nginx2七层代理

192.168.120.20 tomcat1 动态网页

192.168.120.50 tomcat2 动态网页

进入代理服务器

 vim /usr/local/nginx/conf/nginx.conf

systemctl restart nginx

vim /usr/local/nginx/html/index.html

Nginx1

vim /usr/local/nginx/conf/nginx.conf

 vim /usr/local/nginx/html/index.html

   

Nginx2

vim /usr/local/nginx/conf/nginx.conf

vim /usr/local/nginx/html/index.html

Tomcat1

vim /usr/local/tomcat/conf/server.xml

148行删除

mkdir /usr/local/tomcat/webapps/test

vim /usr/local/tomcat/webapps/test/index.jsp

cd /usr/local/tomcat/bin

./startup.sh

tomcat2

vim /usr/local/tomcat/conf/server.xml

148行删除

mkdir /usr/local/tomcat/webapps/test

vim /usr/local/tomcat/webapps/test/index.jsp

cd /usr/local/tomcat/bin

./startup.sh
