几种常见的启动脚本

1.spring boot （jar包形式）启停

#!/usr/bin/env bash
APP_NAME=whale-uip-datasource-0.0.1-SNAPSHOT
#JVM参数
JVM_OPTS="-DPGM_ID=$APP_NAME -Dname=$APP_NAME -Xmx1024M -XX:-UseGCOverheadLimit -Xmx512M -XX:PermSize=256M -XX:MaxPermSize=512M"
JAR_FILE=$APP_NAME.jar
start(){
    nohup java -jar $JVM_OPTS $JAR_FILE --spring.config.location=./config/application-fjprod.yml &
    echo "starting completed,press CTRL+C to exit >>>>>"
}

stop(){
    `ps -ef|grep DPGM_ID=$APP_NAME|grep -v grep|awk '{print "kill -9 "$2}'`
}

case $1 in
    start) start;;
    stop) stop;;
        *) echo "require start|stop" ;;
esac

停止命令 ./***.sh stop

2.项目类 main方式启停

启动脚本：

#!/bin/sh

# JDK路径
# JAVA_HOME="/usr/java/jdk1.6.0_31"

# Java程序主体所在的目录
APP_HOME=.

#设置进程编码
APP_CODE=IOMC_HNYD_PROVIDER

# Java程序日志所在的目录
APP_LOG=$APP_HOME/logs

# JVM启动参数
# -server：一定要作为第一个参数，多个CPU时性能佳
# -Xloggc：记录GC日志，建议写成绝对路径，如此便可在任意目录下执行该shell脚本
JAVA_OPTS="-server -Xms64m -Xmx64m -Xloggc:$APP_LOG/gc.log"

# Java主程序，也就是main(String[] args)方法类
APP_MAIN=com.ztesoft.iomc.web.server.Bootstrap

# classpath参数，包括指定lib目录下的所有jar
OLDCLASSPATH=${CLASSPATH}
CLASSPATH=.
for thirdjar in $APP_HOME/lib/*.jar;
do
   CLASSPATH=$CLASSPATH:$thirdjar
done
if [ "$OLDCLASSPATH" != "" ]; then
  CLASSPATH=${CLASSPATH}:${OLDCLASSPATH}
fi
echo $CLASSPATH
# 初始化全局变量，用于标识交易前置系统的PID（0表示未启动）
appPID=0

# 获取Java应用的PID
# ------------------------------------------------------------------------------------------------------
# 说明：通过JDK自带的jps命令，联合Linux中的grep命令，可以准确查找到Java应用的PID
#       [jps -l]表示显示Java主程序的完整包路径
#       awk命令可以分割出PID（$1部分）及Java主程序名称（$2部分）
# 例子：[$JAVA_HOME/bin/jps -l | grep $APP_MAIN]命令执行，会看到[5775 com.cucpay.tradeportal.MainApp]
# 另外：这个命令也可以取到程序的PID-->[ps aux|grep java|grep $APP_MAIN|grep -v grep|awk '{print $2}']
# ------------------------------------------------------------------------------------------------------
getAppPID(){
    #javaps=`$JAVA_HOME/bin/jps -l | grep $APP_CODE`
    appps=`ps -ef|grep java|grep $APP_CODE`
 
   if [ -n "$appps" ]; then
        appPID=`echo $appps | awk '{print $2}'`
    else
        appPID=0
    fi
}

# 启动Java应用程序
# ------------------------------------------------------------------------------------------------------
# 1、调用 getAppPID() 函数，刷新$appPID全局变量
# 2、若程序已经启动（$appPID不等于0），则提示程序已启动
# 3、若程序未被启动，则执行启动命令
# 4、启动命令执行后，再次调用getAppPID()函数
# 5、若步骤4执行后，程序的PID不等于0，则打印Success，反之打印Failed
# 注意：[echo -n]表示打印字符后不换行
# 注意：[nohup command > /path/nohup.log &]是将作业输出到nohup.log，否则它会输出到该脚本目录下的nohup.out中
# ------------------------------------------------------------------------------------------------------
start(){
    getAppPID
    echo "==============================================================================================="
    if [ $appPID -ne 0 ]; then
        echo "$APP_CODE already started(PID=$appPID)"
        echo "==============================================================================================="
    else
        echo -n "Starting $APP_CODE"
        #nohup $JAVA_HOME/bin/java $JAVA_OPTS -classpath $CLASSPATH $APP_MAIN > $APP_LOG/nohup.log &
        nohup $JAVA_HOME/bin/java -DPGM_ID=$APP_CODE -DAPP_NAME=$APP_CODE $JAVA_OPTS -cp .:./bin:${CLASSPATH} -Dfile.encoding=utf-8 $APP_MAIN > $APP_LOG/nohup.log &       
        getAppPID
        if [ $appPID -ne 0 ]; then
            echo "(PID=$appPID)...[Success]"

        fi
    fi
}

# 调用启动命令
start
tail -f ./logs/nohup.log

启动命令 ./***.sh start

停止脚本：

#!/bin/sh
#APP_MAIN=com.ztesoft.iomc.web.server.WebBootstrap
APP_CODE=IOMC_HNYD_PROVIDER

appPID=0

getAppPID(){
    #javaps=`$JAVA_HOME/bin/jps -l | grep $APP_CODE`
    appps=`ps -ef|grep java|grep $APP_CODE`
    if [ -n "$appps" ]; then
        appPID=`echo $appps | awk '{print $2}'`
    else
        appPID=0
    fi
}

# 停止Java应用程序
# ------------------------------------------------------------------------------------------------------
# 1、调用getAppPID()函数，刷新$appPID全局变量
# 2、若程序已经启动（$appPID不等于0），则开始执行停止程序操作，否则提示程序未运行
# 3、使用[kill -9 PID]命令强制杀掉进程
# 4、使用[$?]获取上一句命令的返回值，若其为0，表示程序已停止运行，则打印Success，反之打印Failed
# 5、为防止Java程序被启动多次，这里增加了反复检查程序进程的功能，通过递归调用shutdown()函数的方式，反复kill
# 注意：Shell编程中，[$?]表示上一句命令或者上一个函数的返回值
# ------------------------------------------------------------------------------------------------------

stop(){
    getAppPID
    echo "==============================================================================================="
    if [ $appPID -ne 0 ]; then
        echo -n "Stopping $APP_CODE(PID=$appPID)..."

3.指定jdk版本，启动spring boot

启动脚本

nohup /app/weblogic/bea923/jdk1.8.0_11/bin/java -server  -Xmx2048m -Xms2048m -Xss256k -jar sim-outyd-server-0.0.1-SNAPSHOT.jar &

View Code

停止脚本

PID=$(ps -ef | grep sim-outyd-server-0.0.1-SNAPSHOT.jar | grep -v grep | awk '{ print $2 }')
if [ -z "$PID" ]
then
    echo Application is already stopped
else
    echo kill $PID
    kill $PID
fi

View Code

重启脚本

echo stop application
source stop.sh
echo start application
source start.sh
sleep 3
tail -f logs/msg.log

View Code

调用直接使用./脚本名.sh

4.spring cloud完整版启动脚本

下面脚本包含start、stop、status

#!/usr/bin/env bash
APP_NAME=gateway-0.0.1-SNAPSHOT
#JVM参数
#JVM_OPTS="-DPGM_ID=$APP_NAME -Dname=$APP_NAME -Xmx1024M -XX:-UseGCOverheadLimit -Xmx512M -XX:PermSize=256M -XX:MaxPermSize=512M"
JVM_OPTS="-DPGM_ID=$APP_NAME -Dname=$APP_NAME"
JAR_FILE=$APP_NAME.jar

start(){
    nohup java -jar $JVM_OPTS $JAR_FILE >/dev/null 2>&1&
    P_ID=`ps -ef | grep -w $JAR_FILE | grep -v "grep" | awk '{print $2}'`
    echo "$APP_NAME is running(PID=$P_ID)"
}

stop(){
    P_ID=`ps -ef | grep -w $JAR_FILE | grep -v "grep" | awk '{print $2}'`
    if [ "$P_ID" == "" ]; then
        echo "===$APP_NAME process not exists or stop success"
    else
        kill -9 $P_ID
        echo "$APP_NAME killed success"
    fi
}

status(){
    P_ID=`ps -ef | grep -w $JAR_FILE | grep -v "grep" | awk '{print $2}'`
    if [ "$P_ID" == "" ]; then
        echo "===$APP_NAME is not running"
    else
        echo "$APP_NAME is running(PID=$P_ID)"
    fi
}

case $1 in
    start) start;;
    stop) stop;;
    status) status;;
        *) echo "require start|stop" ;;
esac
exit 0

在部署上面脚本后，可以再编写一个统一shell脚本，一键启动一系列的sh脚本。

#!/bin/sh

case "$1" in


start)
        ## 启动gateway
        echo "--------gateway 开始启动--------------"
        cd /home/app/gateway
        ./gateway.sh start 
        echo "--------gateway 启动成功--------------"
 
        ;;
stop)

        echo "--------gateway 开始停止--------------"
        cd /home/app/gateway
        ./gateway.sh stop 
        echo "--------gateway 停止成功--------------"
        
        ;;
        
status)

        cd /home/app/gateway
        ./gateway.sh status 

        ;;
restart)
        $0 stop
        sleep 2
        $0 start
        echo "===restartAll success==="
        ;;   
esac    
exit 0

5.同时启停多个docker容器

下面脚本包含start、stop、status

#!/bin/bash

containerIDs="5804f51e186 07252160a61 fae55fc3167"
statusLived="live"
statusdead="Dead"
notExistContainer="None"
retryCount=1

function GetContainerStatus(){
   containerExist=$(sudo docker ps -a | grep -i $1 | wc -l )   
   if [ ${containerExist} -gt 0 ]
     then
       pid=$(sudo docker stats --format "{{.PIDs}}" --no-stream $1 )
       if [ "${pid}" != "0" ]
         then   
           echo "${statusLived}"
       else
           echo "${statusdead}"
       fi
    else
      echo "${notExistContainer}" 
   fi
}




function StartContainer(){
  sudo docker restart $1
}

function StopContainer(){
  sudo docker stop $1
}

start(){
    for containerID in ${containerIDs}
     do
       for((i=1;i<=${retryCount};i++))
       do
        status=$(GetContainerStatus ${containerID} )
        echo "Container ${containerID} status is ${status}"
        
        if [ "${status}" == ${statusLived}  ]
          then
            echo "Container ${containerID} already running"
            break
        fi

        if [ "${status}" == ${notExistContainer}  ]
          then
            echo "Container ${containerID} not existed"
            break
        fi

        if [ "${status}" == ${statusdead}  ]
          then
            echo "Container ${containerID} stopped ,start container"
            StartContainer ${containerID}
            verifyStatus=$(GetContainerStatus ${containerID} )
            if [ "${verifyStatus}" == ${statusLived}  ]
               then
                 echo "start container ${containerID} success "
                 break
            else
               echo "${i} retry start container"
               StartContainer ${containerID}
            fi
        fi
      done
    done
}

stop(){
    for containerID in ${containerIDs}
     do
      for ((i=1;i<=${retryCount};i++))
        do
         status=$(GetContainerStatus ${containerID} )
         echo "Container ${containerID} status is ${status}"
         
         if [ "${status}" == ${statusdead}  ]
          then
            echo "Container ${containerID} already stopped"
            break
         fi

         if [ "${status}" == ${notExistContainer}  ]
           then
            echo "Container ${containerID} not existed"
            break
         fi

         if [ "${status}" == ${statusLived}  ]
           then
             echo "Container ${containerID} is lived ,stop container"
             StopContainer ${containerID}
             verifyStatus=$(GetContainerStatus ${containerID} )
             if [ "${verifyStatus}" == ${statusdead}  ]
               then
                  echo "stop container ${containerID} success "
                  break
             else
                echo "${i} retry stop container"
                StopContainer ${containerID}
             fi
          fi
       done
    done
}


status(){
    for containerID in ${containerIDs}
     do
      for ((i=1;i<=${retryCount};i++))
        do
         status=$(GetContainerStatus ${containerID} )
         echo "Container ${containerID} status is ${status}"
       done
    done
}

case $1 in
    start) start;;
    stop) stop;;
    status) status;;
        *) echo "require start|stop" ;;
esac
exit 0
