redis啟動過程

redis啟動分為兩種：開發環境、生產環境

一、開發環境

        1、cd redis-2.8.13/src

        2、 ./redis-server 啟動服務端

        3、./redis-cli       啟動用戶端

二、生產環境（隨系統開機啟動）

        1、配置redis初始化指令碼（樣本在/redis-2.8.13/utils/下），並放在/etc/init.d/下（命名為redis_6379）

#!/bin/sh

#

# Simple Redis init.d script conceived to work on Linux systems

# as it does use of the /proc filesystem.

REDISPORT=6379

EXEC=/usr/local/bin/redis-server

CLIEXEC=/usr/local/bin/redis-cli

PIDFILE=/var/run/redis_${REDISPORT}.pid

CONF="/etc/redis/${REDISPORT}.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

        ;;

    stop)

        if [ ! -f $PIDFILE ]

        then

                echo "$PIDFILE does not exist, process is not running"

        else

                PID=$(cat $PIDFILE)

                echo "Stopping ..."

                $CLIEXEC -p $REDISPORT shutdown

                while [ -x /proc/${PID} ]

                do

                    echo "Waiting for Redis to shutdown ..."

                    sleep 1

                done

                echo "Redis stopped"

        fi

        ;;

    *)

        echo "Please use start or stop as first argument"

        ;;

esac

        如何修改此初始化指令檔：修改redis服務端要監聽的連接埠號碼：6379（預設）

 

        二、在/etc目錄下建立目錄：/etc/redis  和   /var/redis/6379，並存放相應的檔案

    1、/etc/redis/    存放設定檔，命名為6379.cof （模板在原始碼目錄/redis-2.8.13/）

edis configuration file example

daemonize no                    //修改為yes    使redis以守護進程模式啟動

pidfile /var/run/redis.pid        //修改為/var/run/redis_6379.pid    設定redis的PID檔案的路徑

port 6379                            //修改為6379    監聽連接埠號碼

timeout 0

loglevel notice

aof-rewrite-incremental-fsync yes

    2、在/var/redis/連接埠號碼 目錄下存放 持久化檔案 （使用該組件時在存放）

    3、sudo update-rc.d   redis_6379   defaults  (配置隨機啟動命令  redis_6379為初始化指令檔)
