centos redis 自动重启

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

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 yes

4，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
