实验环境：CentOS7
#两台tomcat的基本配置如下：
[[email protected] localhost]#setenforce 0
[[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="200" enableLookups="False"
connectionTimeout="60000" address="172.16.252.142"
redirectPort="8443" />
[[email protected] localhost]#vim /usr/share/tomcat/webapps/test/index.jsp

[[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：
[[email protected]~ localhost]#setenforce 0
[[email protected]~ localhost]#iptables -F
[[email protected]~ localhost]#yum -y install nginx-1.10.2-1.el7.ngx.x86_64.rpm
[[email protected]~ localhost]#vim /etc/nginx/nginx.conf

}
include /etc/nginx/conf.d/*.conf;

}
#httpd做负载均衡：
[[email protected]~ localhost]#yum -y install httpd
[[email protected]~ localhost]#httpd -M
