redis第二篇：Centos下配置Redis开机启动

1、下载安装

wget http://redis.googlecode.com/files/redis-2.2.13.tar.gz
tar -zxf redis-2.2.13.tar.gz
cd redis-2.2.13
make
sudo make install  
cp redis.conf /etc

install的时候，redis的命令会被拷贝到/usr/local/bin下面

2，建立用户与日志目录

第一次启动Redis前，建议为Redis单独建立一个用户，并新建data和日志文件夹

sudo useradd redis
sudo mkdir -p /var/lib/redis
sudo mkdir -p /var/log/redis
sudo chown redis.redis /var/lib/redis ＃db文件放在这里，要修改redis.conf
sudo chown redis.redis /var/log/redis

3，配置init脚本

其实github上很多老外写好的启动脚本，不过大部分都是ubuntu的，对于Centos，也有一份

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 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
