httpd+tomcat(3) -- mod_jk
全部系统采用centos7.1
各节点配置好hosts文件
cat /etc/hosts
172.16.92.2 node2.centos7.com node2
172.16.92.3 node3.centos7.com node3
172.16.92.5 node5.centos7.com node5
node2, node3 --> tomcat ( jsp网站服务器 )
node5 --> httpd(mod_jk) 反向代理至tomcat
================ node2 172.16.92.2/16 ===================
安装JDK(光盘源)
mount /dev/cdrom /mnt/cdrom/
yum -y install java-1.7.0-openjdk
安装二进制tomcat
wget http://archive.apache.org/dist/tomcat/tomcat-8/v8.0.23/bin/apache-tomcat-8.0.23.tar.gz
tar xf apache-tomcat-8.0.23.tar.gz -C /usr/local
