PROSAGA码农传奇-Linux/Unix-Crontab在系统重启时没有运行shell脚本

<div class =“post-text”itemprop =“text”>
  <P>
    1）创建
     <code>
      /etc/init.d/example
    </code>
     具有此类内容的脚本：
  </p>
   <pre>
    <code>
      #!/bin/sh

### BEGIN INIT INFO
# Provides:          Example APP
# Required-Start:
# Required-Stop:
# Default-Start:     2 3 4 5
# Default-Stop:      1 0 6
# Short-Description: ...
# Description: ...
### END INIT INFO

APP_NAME="Example APP"
APP_DIR="/path/to/example"

USER="example"
GROUP="example"

USAGE="Usage: $0 {start|stop|restart|status}"

start_app() {
    echo "Starting $APP_NAME ..."
    su - $USER -c "cd $APP_DIR && ./example"
}

stop_app() {
    echo "NOT IMPLEMENTED"
}

status_app() {
    echo "NOT IMPLEMENTED"
}

restart_app() {
    echo "NOT IMPLEMENTED"
}

case "$1" in
    start)
        start_app
    ;;

stop)
        stop_app
    ;;

restart)
        restart_app
    ;;

status)
        status_app
    ;;

*)
        echo $USAGE
        exit 1
    ;;
esac

</code>
  </pre>
  <P>
    或者干脆：
  </p>
   <pre>
    <code>
      #!/bin/sh

APP_NAME="Example APP"
APP_DIR="/path/to/example"

USER="example"
GROUP="example"

USAGE="Usage: $0 {start}"

start_app() {
    echo "Starting $APP_NAME ..."
    su - $USER -c "cd $APP_DIR && ./example"
}

case "$1" in
    start)
        start_app
    ;;

*)
        echo $USAGE
        exit 1
    ;;
esac

</code>
  </pre>
  <P>
    2）给出默认值并启用：
  </p>
   <pre>
    <code>
      cd /etc/init.d
chmod +x example
update-rc.d example defaults
update-rc.d example enable

</code>
  </pre>
</DIV>
