1、编写sentinel的启动脚本
[root@master ~]# vim /etc/init.d/sentinel
#!/bin/sh
#
# redis start up the redis server daemon
#
# chkconfig: 345 98 98
# description: redis service in /etc/init.d/redis
# chkconfig --add redis or chkconfig --list redis
# service redis start or service redis stop
# processname: redis-sentinel
# config: /etc/redis.conf
# 注意不同位置要修改变量
PATH=/usr/local/bin:/sbin:/usr/bin:/bin
REDISPORT=26379
EXEC=/usr/local/redis/bin/redis-sentinel
REDIS_CLI=/usr/local/redis/bin/redis-cli
PIDFILE=/var/run/sentinel.pid #修改pid文件名
CONF="/usr/local/redis/sentinel.conf" #修改配置文件名
case "$1" in
status)
ps -ef|grep redis|grep 26379
;;
start)
if [ -f $PIDFILE ]
then
echo "$PIDFILE exists, process is already running or crashed"
else
echo "Starting Redis server..."
$EXEC $CONF
fi
if [ "$?"="0" ]
then
echo "Redis is running..."
fi
;;
stop)
if [ ! -f $PIDFILE ]
then
echo "$PIDFILE does not exist, process is not running"
else
PID=$(cat $PIDFILE)
echo "Stopping ..."
$REDIS_CLI -p $REDISPORT SHUTDOWN
while [ -x ${PIDFILE} ]
do
echo "Waiting for Redis to shutdown ..."
sleep 1
done
echo "Redis stopped"
fi
;;
restart|force-reload)
${0} stop
${0} start
;;
*)
echo "Usage: /etc/init.d/redis {start|stop|restart|force-reload}" >&2
exit 1
esac
2、添加到系统服务
[root@localhost ~]# chkconfig --add sentinel
[root@localhost ~]# ll /etc/rc.d/rc3.d/ |grep sentinel # 查看本级下所有服务的启动顺序;
lrwxrwxrwx 1 root root 18 5月 16 16:32 S98sentinel -> ../init.d/sentinel
$ ln -s /etc/rc.d/init.d/apache /etc/rc.d/rc3.d/S60apache
S 是start的简写、代表启动;
K 是kill的简写、代表关闭;
98 数字代表启动的顺序。60以后通常是比较保险的数字，因为别的服务都启动了；
