读取INPUT_STRING 案例$ INPUT_STRING

stop)

    check=`netstat -na | grep 8080 | awk '{print $6}'|head -1`
    if [ "$check" = "TIME_WAIT" ]; then
        echo "DEFAULT TOMCAT PORT IS LISTENING, SO ITS stopped already..."
    else 
        sh /opt/apache-tomcat-8.0.39/bin/shutdown.sh > /dev/null 2>&1
    echo "Tomcat server is stopped....."

    fi

这里我的代码是找到仅在8080端口上运行的tomcat服务器，以便很容易找到tomcat是否正在运行。但实际上我需要的是停止/启动tomcat服务器，如果它正在运行或在其他一些端口中停止状态......

Answer 1

创建一个正在运行tomcat的pids数组，并检查每一个：

declare -a list
list=( `ps -AChS | grep '[t]omcat' | awk '{ print $1 }'`)  
for i in ${list[*]} ; 
    do netstat -vlp tcp | awk '{ print $6, $9 }' | grep "$i" ; 
done
unset "$list"

我在这里创建一个tomcat pids数组，然后使用grep查找每个pid的网络状态。一旦我完成了循环，我就清除了阵列。注意：netstat在各种操作系统上有不同的实现，在我的例子中，我使用的是verbose，它显示了进程的pid和tcp的过滤。

使用catalina.sh启动或停止服务，例如catalina.sh stop

# This script is works based on tomcat server is running or stopped status. if it is stopped I need to restart it by giving option as start otherwise stop based on the requirement....

#!/bin/sh
echo "Choose Your Option---- status or stop.."
echo 
echo "Enter Your Option ..."
path=`whereis -l tomcat | grep tomcat | sed 's/bin: //' |head -1`
echo $path

  read INPUT_STRING
  case $INPUT_STRING in

        else 
            sh $path/shutdown.sh > /dev/null 2>&1
        echo "The Tomcat server is stopped successfully..."
        fi

    start)

        else 
            sh $path/startup.sh > /dev/null 2>&1
        echo "Tomcat server is started....."
            fi
