Centos 6和Centos 7环境下实现程序开机自启动

---

创建服务启动和关停脚本

---

1. vim msgsend-start.sh

#!/bin/bash
export JAVA_HOME=/usr/java/jdk1.7.0_79
export PATH=$PATH:$JAVA_HOME/bin
java -jar /service/msgsend.jar > /var/log/msgsend.log &
echo $! > /var/run/msgsend.pid

2. vim msgsend-stop.sh

#!/bin/sh
PID=$(cat /var/run/msgsend.pid)
kill -9 $PID

---

Centos 6环境下启动

---

 

# vim /etc/init.d/msgsend

#!/bin/sh
# chkconfig: 2345 10 90
# description: Start and Stop msgsend
#
# Simple msgsend init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem.

startexec=/home/riverhan/msgsend-start.sh
stopexec=/home/riverhan/msgsend-stop.sh
PIDFILE=/var/run/msgsend.pid

case "$1" in
start)
if [ -f $PIDFILE ]
then
echo "$PIDFILE exists, process is already running or crashed"
else
echo "Starting msgsend service..."
$startexec
fi
;;
stop)
if [ ! -f $PIDFILE ]
then
echo "$PIDFILE does not exist, process is not running"
else
PID=$(cat $PIDFILE)
$stopexec
echo "msgsend service stopped"
fi
;;
*)
echo "Please use start or stop as first argument"
;;
esac
