Shell manages SpringBoot production environment services - reprint

If Spring Boot runs in a production environment, if it is packaged as a jar with maven, then shut down and restart the service, which is very inconvenient every time you operate. Here, a shell script is written for unified management.

# description: Auto-starts boot

Tag="PublishImageApplication"
MainClass="com.yoke.PublishImageApplication"
Lib="/test/lib/"
Log="/test/run.log"
echo $Tag
RETVAL="0"

# See how we were called.
function start() {
    echo  $Log
    if [ ! -f $Log ]; then
        touch $Log
    be
    nohup java -Dappliction=$Tag -Djava.ext.dirs=$Lib":${JAVA_HOME}/jre/lib/ext" $MainClass > $Log 2>&1 &  
    tailf $Log
}


function stop() {
    pid=$(ps -ef | grep -v 'grep' | egrep $Tag| awk '{printf $2 " "}')
    if [ "$pid" != "" ]; then      
        echo -n "boot ( pid $pid) is running"
        echo
        echo -n $"Shutting down boot: "
        pid=$(ps -ef | grep -v 'grep' | egrep $Tag| awk '{printf $2 " "}')
        if [ "$pid" != "" ]; then
            echo "kill boot process"
            kill -9 "$pid"
        be
        else
             echo "boot is stopped"
        be

    status
}

function status()
{
    pid=$(ps -ef | grep -v 'grep' | egrep $Tag| awk '{printf $2 " "}')
    #echo "$pid"
    if [ "$pid" != "" ]; then
        echo "boot is running,pid is $pid"
    else
        echo "boot is stopped"
    be
}



function usage()
{
   echo "Usage: $0 {start|stop|restart|status}"
   RETVAL="2"
}

# See how we were called.
RETVAL="0"
case "$1" in
    start)
        start
        ;;
    stop)
        stop
        ;;
    restart)
        stop
        start
        ;;
    reload)
        RETVAL="3"
        ;;
    status)
        status

exit $RETVAL

 Tag: It plays a role in identifying the program running flag. If the server runs multiple java programs, you need to use java -Dappliction to distinguish the corresponding programs

MainClass: is the SpringBoot main class that corresponds to the running of the program

Lib: is all the jar paths of the boot program in the production server environment

Log: is to record the boot program running all log storage paths

For example, the script starts the command in 
/boot/run_boot.sh 
: /boot/run_boot.sh start 
Restart command: /boot/run_boot.sh restart 
Shutdown command: /boot/run_boot.sh stop 
is it running: /boot/run_boot.sh status
