本文介绍了一个用于自动化启动、停止和更新PlayFramework项目的Shell脚本。脚本支持通过GIT进行项目更新，并能配置项目运行的端口、内存参数等。此外，还提供了修改后的脚本示例，包括对项目状态的检查、日志记录等功能。

### BEGIN vars

### END vars
 
# Exit immediately if a command exits with a nonzero exit status.
set -e
 
update() {
    echo "Updating"
 
    cd $BASE_DIR || exit
 
    unset GIT_DIR
    # Update repo
    git pull origin master
 
    cd $BASE_DIR
    # Creating new project (MUST BE ON THE GOOD DIR)
    /opt/play/$PLAY_VERSION/play clean compile stage
}
 
start() {
    echo "Starting server"
    eval $BASE_DIR$ENV"/target/start -Dhttp.port="$PORT" -Dconfig.file="$CONF_PATH" &"
}
 
stop() {
    echo "Stopping server"
    if [ -f $BASE_DIR"/RUNNING_PID" ];then
        kill `cat $BASE_DIR$ENV"/RUNNING_PID"`
    fi
}
 
case "$1" in
    start)
        start
    ;;
    stop)
        stop
    ;;
    restart)
        stop
        start
    ;;
    update)
        update
    ;;
    force-restart)
        stop
        update
        start
    ;;
    *)
        echo $"Usage: $0 {start|force-restart|stop|restart|update}"
esac
 
exit 0

如下是我的修改后的脚本：

#!/bin/bash

### BEGIN vars
PORT="XXX"
BASE_DIR="XXXXX"
PLAY_NAME="XXXXXX"

PLAY_VERSION=2.7.3 
### END vars

# Exit immediately if a command exits with a nonzero exit status.
set -e

run() {
    apiPid=`ps -ef | grep $PLAY_NAME | grep -v grep|awk '{print $2}'`
    if [ -z "$apiPid" ]
    then
		    echo "Starting server"
		    rm -f ${BASE_DIR}/RUNNING_PID
		    nohup ${BASE_DIR}/bin/${PLAY_NAME} -Dplay.http.secret.key=XXXXXXXXXX -Dhttp.port=${PORT} > ${BASE_DIR}/logs/${PLAY_NAME}.logs 2>&1 &
    else
        echo "${PLAY_NAME} is already running....."
        netstat -nlp | grep "$apiPid"
    fi

}

stop() {
    rm -f ${BASE_DIR}/RUNNING_PID
    apiPid=`ps -ef | grep $PLAY_NAME | grep -v grep|awk '{print $2}'`
    if [ -z "$apiPid" ]
    then
        echo "$PLAY_NAME is Not running....."
    else
        echo "Stopping server"
        kill -s 9 `ps -ef | grep $PLAY_NAME | grep -v grep |awk '{print $2}'`
    fi    
}

status() {
    #echo "Status server"
    apiPid=`ps -ef | grep $PLAY_NAME | grep -v grep|awk '{print $2}'`
    if [ -z "$apiPid" ]
    then
        echo "$PLAY_NAME is Not running....."
    else
        echo "$PLAY_NAME is running....."
        netstat -nlp | grep "$apiPid"
    fi

}

case "$1" in
    run)
        run
    ;;
    stop)
        stop
    ;;
    restart)
        stop
        run
    ;;
    status)
        status
    ;;
    *)
        echo $"Usage: $0 {run|stop|restart|status}"
esac

exit 0
