httpd+tomcat(3)

samdung

　　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

apache基于mod_jk模块对多个tomcat负载均衡并实现会话(session)绑定

vim /etc/httpd/conf.d/workers.properties

worker.list = lbcluster1,stat1
worker.TomcatA.type = ajp13
worker.TomcatA.host = 172.16.92.2
worker.TomcatA.port = 8009
worker.TomcatA.lbfactor = 1
worker.TomcatB.type = ajp13
worker.TomcatB.host = 172.16.92.3
worker.TomcatB.port = 8009
worker.TomcatB.lbfactor = 1
worker.lbcluster1.type = lb
worker.lbcluster1.sticky_session = 1    #修改
worker.lbcluster1.balance_workers = TomcatA, TomcatB
worker.stat1.type = status
=====================================

httpd -t
systemctl reload httpd
(systemctl start httpd)
