shell 命令管理tomcat

我们一般在linux 上的生产环境管理tomcat 是使用tomcat 目录下面的几个sh 文件来控制的，有时候tomcat 进程会没有完全结束，然后我们再次启动很容易咋成启动二个tomcat 这里集成一个shell 命令来管理。

# description: Auto-starts tomcat

Dir="/tomcat/"
echo $Dir

RETVAL="0"

# See how we were called.
function start() {
        echo -n "Starting Tomcat: "
    cd $Dir
        ./bin/startup.sh
        echo
}

function stop2() {
        stop
    echo >$Dir/logs/catalina.out
}

function stop() {
    pid=$(ps -ef | grep -v 'grep' | egrep $Dir"bin/bootstrap.jar"| awk '{printf $2 " "}')
    if [ "$pid" != "" ]; then
                echo -n "tomcat ( pid $pid) is running" 

                echo 

                echo -n $"Shutting down Tomcat: "
        cd $Dir
                ./bin/shutdown.sh
