httpd or Nginx load balancing tomcat

Lab Environment: CentOS7

#两台tomcat的基本配置如下: [[email protected] localhost] #setenforce0[email protected] localhost] #iptables-f[[email protected] localhost] #yum-y install java-1.8.0-openjdk-devel tomcat Tomcat-webapps tomcat-admin-webapps[[email protected] localhost] #chown tomcat.tomcat/usr/share/tomcat/webapps/test/*[email protected] localhost] #chown tomcat.tomcat test[[email protected] localhost] #vim/etc/tomcat/server.xml <connector port= "8081" protocol= "http/1.1" maxthreads= "$" enablelookups= "False"ConnectionTimeout= "60000" address= "172.16.252.142"Redirectport= "8443"/>[email protected] localhost] #vim/usr/share/tomcat/webapps/test/index.jsp<%@ page language= "Java"%><%@ page import= "java.util.*"%>Out.println ("Tomcat1 Mini"); %> </body>[email protected] localhost] #vim/usr/share/tomcat/conf/tomcat-users.xml<role rolename= "Manager-gui"/><user username= "Tomcat" password= " 123456 "roles=" Manager-gui "/>

#第三台主机安装Nginx: 172.16.253.177

#ngixn做负载均衡:

#httpd做负载均衡:
