来源：互联网发布：莫一兮知乎编辑：程序博客网时间：2024/06/07 05:02

下载安装nginx

brew install nginx

其被安装路径 /usr/local/etc/nginx
启动命令

sudo nginx

接着输入个人密码就可以了
浏览器访问
localhost:8080
这里写图片描述
关闭命令

sudo nginx -s stop

复制多份tomcat，命名为 tomcat-1、tomcat-2
修改他们的server.xml文件，即 tomcat-1以81开头、tomcat-2以82开头

//tomcat-1的server.xml<Server port="8105" shutdown="SHUTDOWN"><Connector URIEncoding="UTF-8" connectionTimeout="20000" port="8180" protocol="HTTP/1.1" redirectPort="8443"/><Connector port="8109" protocol="AJP/1.3" redirectPort="8443"/>

//tomcat-2的server.xml<Server port="8205" shutdown="SHUTDOWN"><Connector URIEncoding="UTF-8" connectionTimeout="20000" port="8280" protocol="HTTP/1.1" redirectPort="8443"/><Connector port="8209" protocol="AJP/1.3" redirectPort="8443"/>

然后到各个tomcat的bin目录下启动服务器

cd $TOMCAT_HOME/bin./startup.sh

可以通过浏览器查看效果
localhost:8180 和 localhost:8280

接下来配置nginx，找到ngnix.conf文件并修改

//添加 upstream localhost {      #ip_hash;       server localhost:8180;      server localhost:8280;    }//修改 location / {            root html;            index index.html index.htm;            proxy_pass  http://localhost;              proxy_set_header X-Real-IP $remote_addr;             proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;             proxy_redirect HOST default;         }

启动nginx即
sudo nginx

然后各种测试请求是否随机到各台tomcat服务器
