Redis 安裝步驟

1. 下載Redis

(1)擷取許可權:su root

(2)規劃好下載的目錄:mkdir /usr/local/soft/

(3)進入建立的目錄,準備下載:cd /usr/local/soft/

(4)下載redis最新穩定版:

wget http://download.redis.io/releases/redis-3.0.0.tar.gz

2.  解壓並安裝redis

(1)解壓tar包:tar zxvf redis-3.0.0.tar.gz

(2)進入解壓後出現的新目錄:cd redis-3.0.0

(3)編譯源碼:make

(4)校正編譯是否正確:make test

3. 手工啟動redis,測試redis是否運行正常

(1)在當前redis目錄中輸入命令啟動Redis:src/redis-server

(2)檢查進程是否有Redis了:ps aux | grep redis,可以看見進程列表中有一個叫“src/redis-server”的進程了

(3)啟動redis內建的用戶端,進行測試:

       啟動用戶端並串連本地Redis:  src/redis-cli 

        > set foo bar     -- 提示 “ok”說明設定索引值正常。

        > get foo           -- 能夠提示返回正確的“bar”,說明運行正常。

        > quit               -- 退出用戶端

4. Redis加入開機自啟動序列

(1)redis.conf 設定檔裡面的daemonize no 改成 daemonize yes 

(2)編寫指令碼/etc/init.d/redis:

###########################

#chkconfig: 2345 10 90

#description: Start and Stop redis

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

    REDISPORT=6379 #實際環境而定

    EXEC=/usr/local/soft/redis-3.0.0/src/redis-server #實際環境而定

    REDIS_CLI=/usr/local/soft/redis-3.0.0/src/redis-cli #實際環境而定

    PIDFILE=/var/run/redis.pid

    CONF="/usr/local/soft/redis-3.0.0/redis.conf" #實際環境而定

    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 "Redis is 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

##############################

(3)執行許可權: chmod +x /etc/init.d/redis

(4)開機啟動 :

# 嘗試啟動或停止redis

service redis start

service redis stop

 

# 開啟服務自啟動

sudo chkconfig redis on
