为什么80%的码农都做不了架构师？>>>

以下是定制脚本
下载tomcat 7 并解压缩到/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

下面将tomcat的server.xml，catalina.out，pid分别独立起来。

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  

#项目名称
PROJECT=$2
#java相关
export JAVA_HOME=/opt/jdk7
export JRE_HOME=$JAVA_HOME/jre
export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
export JAVA_OPTS="-Djava.awt.headless=true -Djava.net.preferIPv4Stack=true -server -Xms2g -Xmx2g -Xss256K

export CATALINA_BASE=/opt/tomcat7
export CATALINA_HOME=/opt/tomcat7
export CATALINA_OUT=/home/logs/tomcat/catalina-$PROJECT.out
export CATALINA_PID="/home/logs/PID/catalina-$PROJECT.pid"
CONFIGFILE=$CATALINA_HOME/conf/server-$PROJECT.xml
export CUSTOM_OPTS="-config $CONFIGFILE"

if [[ $1 != "-server" ]]; then

  echo "+Usage: tomcat.sh -server PROJECTNAME {start|stop|restart|status}+";
  exit 1
elif [ -z $2 ]; then
  echo "+Usage: tomcat.sh -server PROJECTNAME {start|stop|restart|status}+";
  exit 1
elif [ -z $3 ]; then
  echo "+Usage: tomcat.sh -server PROJECTNAME {start|stop|restart|status}+";
  exit 1
fi

if [ ! -f $CONFIGFILE ] ; then echo "PROJECT_CONFIG $CONFIGFILE is not exist,please check.";
    exit 1
fi

start(){
        $CATALINA_HOME/bin/startup.sh $CUSTOM_OPTS 
}

stop() {
       $CATALINA_HOME/bin/shutdown.sh -force $CUSTOM_OPTS
}

status() {
       if [ -f $CATALINA_PID ] && ps --no-heading -p `cat $CATALINA_PID`; then
           echo "$PROJECT server is running"
        else
            echo "$PROJECT server is not running"
       fi
}

case "$3" in
   'start')
     start
   ;;
'stop')
   stop
    ;;
'restart')
  stop
  start
  ;;
'status')
  status
;;
*)
 echo "Usage: $0 -server PROJECT {start|stop|restart|status}"
exit 1
esac
exit 0

新建项目projectA,需要初始化如下

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的内容基本如下

<?xml version='1.0' encoding='utf-8'?>
<Server port="8183" shutdown="SHUTDOWN">
  <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="off" />
  <Listener className="org.apache.catalina.core.JasperListener" />
  <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />
  <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />
  <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />
  <GlobalNamingResources>
    <Resource name="UserDatabase" auth="Container"
              type="org.apache.catalina.UserDatabase"
              description="User database that can be updated and saved"
              factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
              pathname="conf/tomcat-users.xml" />
  </GlobalNamingResources>

  <Service name="Catalina">
    <Executor name="tomcatThreadPool" namePrefix="catalina-exec-" maxThreads="500" minSpareThreads="4"/>

    <Connector executor="tomcatThreadPool"
               port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

    <Engine name="Catalina" defaultHost="localhost">

      <Realm className="org.apache.catalina.realm.LockOutRealm">
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
               resourceName="UserDatabase"/>
      </Realm>

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

useradd -M projectA -s /sbin/nologin #添加用户，一个用户对应一个单独项目，禁止login

启动项目ProjectA

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

停止

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

重启

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