httpd+tomcat(3)
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
cd /usr/local
ln -sv apache-tomcat-8.0.23 tomcat
vim /etc/profile.d/tomcat.sh
export CATALINA_HOME=/usr/local/tomcat
export PATH=$PATH:$CATALINA_HOME/bin
================
. /etc/profile.d/tomcat.sh
catalina.sh --help
catalina.sh version
catalina.sh start
windows浏览器访问 http://172.16.92.2:8080/
能看到tomcat首页即可
catalina.sh stop
cd tomcat/conf
cp server.xml{,.bak}
vim server.xml
#添加虚拟主机
#修改
:set nu
:123,139y-> p -> 修改成如下
#修改
==============
mkdir -pv /data/logs
catalina.sh configtest
>全部都是INFO开头的就正常了
(难道是把jar放在 /data/webapps/ROOT/lib 下?)
mkdir -pv /data/webapps/ROOT/{lib,classes,META-INF,WEB-INF}
vim /data/webapps/ROOT/index.jsp
