nginx 模拟动静分离：
基于负载均衡和nginx静态代理来实现
动态资源由tomcat来调用，静态资源由nginx来调用
步骤：
1.准备三个tomcat，端口号分别为8081、8181、8281
2.将项目部署在响应的tomcat中 ，注意：需要将静态资源放在Linux 的其他目录下，三个tomcat共享一个静态资源文件夹（这里放 在/opt/static）
3.配置/usr/local/nginx/conf/nginx.conf文件
配置文件：# 配置动态负载均衡：server myserver {192.168.113.129:8080 weight=5;192.168.113.129:8180 weight=2;192.168.113.129:8280 weight=3;}
配置静态负载均衡：
server mystaticserver {192.168.113.129:89 weight=1;192.168.113.129:90 weight=1;}
定义动态tomcat服务器
server {
listen : 80 ; # 监听80端口
server_name ; # 域名或者ip
location /Easyui_maven/ { # 设置动态资源拦截路径
proxy_pass http://myserver; # 将请求交给响应的负载处理
}
location / { # 只输入域名访问欢迎界面
root html;
index index.html index.htm;
}
location ~ .*/() { # 静态资源
proxy_pass http://mystaticserver; # 交给静态资源处理
}
}
定义静态nginx服务器，
server {
listen : 89 ;# 监听端口
server_name ; # 网站别名
# 拦截路径： 正则表达式，所有后缀为以下资源的路径都被拦截
location ~ .*/(jpg|image|images|js|jsp|png|css|) {
# 文件路径
root /opt/static
}
}
server {
listen : 90； 监听端口：90
root /opt/static;
}
4.启动nginx(在/usr/local/nginx/sbin/ 下执行nginx)
5.启动三个tomcat（在tomcat的bin目录下执行start.sh文件）
6.打开浏览器输入地址：
