nginx+tomcat
全部系統(tǒng)采用centos7.1
各節(jié)點(diǎn)配置好hosts文件
cat /etc/hosts
172.16.92.1?? ?node1.centos7.com?? ?node1
172.16.92.2?? ?node2.centos7.com?? ?node2
172.16.92.3?? ?node3.centos7.com?? ?node3
node2, node3 --> tomcat ( jsp網(wǎng)站服務(wù)器 )
node1 --> nginx反向代理至tomcat
================ node2 172.16.92.2/16 ===================
安裝JDK(光盤(pán)源)
yum -y install java-1.7.0-openjdk
安裝二進(jìn)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
