Tomcat定製化

如下是定製腳本
下載tomcat 7 並解壓縮到/opt下，

wget http://mirrors.noc.im/apache/tomcat/tomcat-7/v7.0.69/bin/apache-tomcat-7.0.69.tar.gz -O - | tar -xzf - -C /opt

mv /opt/apache-tomcat-7.0.69 /opt/tomcat7

yum install tomcat-native

下面將tomcat的server.xml，catalina.out，pid分別獨立起來。

新建：

vim /opt/tomcat7/tomcat.sh

#!/bin/sh
# config:      /opt/tomcat7/conf/server-xxxx.conf
# CATALINA_BASE:     /opt/tomcat7
# CATALINA_OUT:     /home/logs/tomcat/catalina-xxx.out
# server.xml        /opt/tomcat7/conf/server-xxx.xml


#if [ `whoami` = "root" ];then  
#    echo "You're root,please run as Non-Root user."
#    exit 1  
#fi

新建項目projectA,須要初始化以下

mkdir /home/logs/tomcat -p
mkdir /home/logs/PID -p
cp /opt/tomcat7/conf/server.xml /opt/tomcat7/conf/server-projectA.xml

vim /opt/tomcat7/conf/server-projectA.xml

server-projectA.xml的內容基本以下

<?xml version='1.0' encoding='utf-8'?>

      </Realm>

      <Host name="localhost"  appBase="webapps" unpackWARs="false" autoDeploy="false">
        <!--改成你的路徑-->
        <Context docBase="/home/app/projectA-source" path="" reloadable="false"/>
      </Host>
    </Engine>
  </Service>
</Server>

useradd -M projectA -s /sbin/nologin #添加用戶，一個用戶對應一個單獨項目，禁止login

啓動項目ProjectA

sudo -u projectA /opt/tomcat7/bin/tomcat.sh -server projectA start

中止

sudo -u projectA /opt/tomcat7/bin/tomcat.sh -server projectA stop

重啓

sudo -u projectA /opt/tomcat7/bin/tomcat.sh -server projectA restart
