centos redis 自动重启脚本

配置init脚本对于Centos，有一份https://gist.github.com/1335694经过修改，如下：

##########################
PATH=/usr/local/bin:/sbin:/usr/bin:/bin

REDISPORT=6379
EXEC=/usr/local/bin/redis-server
REDIS_CLI=/usr/local/bin/redis-cli

PIDFILE=/var/run/redis.pid
CONF="/etc/redis.conf"

case "$1" in
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

把上述代码存为redis,放到/etc/init.d/下面chmod +x /etc/init.d/redis 其实做成服务启动，也是调用redis-server，如果想让它在后台作为daemon运行，那么需要修改redis.conf,将 daemonize no 改为 daemonize yes4，设定开机启动服务sudo chkconfig redis on 5，启动,停止redis service redis start #或者 /etc/init.d/redis start service redis stop #或者 /etc/init.d/redis stop 6，测试redis

redis-cli
redis 127.0.0.1:6379> set foo 123
OK
redis 127.0.0.1:6379> get foo
"123"
redis 127.0.0.1:6379> exit
