一、環境配置
    1：任何位置建立資料夾
       mkdir redis;cd  redis;mkdir conf;cd conf
       #下載安裝安裝包
       wget http://www.redis.cn/download.html/redis-5.0.3.tar.gz
    2:書寫自動安裝redis的指令碼和自動安裝主從
       cd ..
       vim install.sh
    3:在conf目錄中再編寫啟動指令碼redis
      cd conf;vim redis
       

#!/bin/bash

cd  /usr/local/redis/bin

case $1 in 
start)
    ./redis-server redis.conf | grep "is starting" > /dev/null && echo "redis Successful opening" || echo "redis Open failure"
    ;;
stop)
    ./redis-cli shutdown;ps -ef | grep -v grep | grep  redis-server  && echo "redis Shutdown failure"  || echo "redis Shut down successfully"
    ;;
restart)
    ./redis-cli shutdown;ps -ef | grep -v grep | grep  redis-server  && echo "redis Shutdown failure"  || echo "redis Shut down successfully"
    ./redis-server redis.conf | grep "is starting" > /dev/null && echo "redis Successful opening" || echo "redis Open failure"
    ;;
*)
    exit
    exit
    ;;
esac



       
 

#!/bin/bash



redis-install(){
yum install gcc-c++  wget vim -y

cd conf

#啟動和關閉指令碼
chmod +x redis
cp redis  /usr/bin/

tar -zxf redis-5.0.3.tar.gz
cd redis-5.0.3
make MALLOC=libc
make
cd src
make install PREFIX=/usr/local/redis
cd ..
cp redis.conf /usr/local/redis/bin/
cd ..
rm -rf redis-5.0.3/
cd /usr/local/redis/bin

##讓redis可以後臺啟動
AA=`cat -n redis.conf  | grep daemonize | grep -v "#" | awk '{print $1}'`
sed -i ''"$AA"'c  daemonize yes'   redis.conf

#開機自啟：
echo  "/usr/local/redis/bin/redis-server /usr/local/redis/bin/redis-conf"  >> /etc/rc.local

#建立登入資料庫的命令
cp /usr/local/redis/bin/redis-cli /usr/bin/

clear
echo "啟動 redis start "
echo "關閉 redis stop "
echo "重啟 redis restart"
}


#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~主從搭建~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#注意事項：
#    1：主從模式時matser節點開啟持久化（不開的話，matser節點重啟，從會出現丟失資料）
#	2：先開啟主機上的服務，後開機從機上的服務
#	3：預設是開啟保護模式protected-mode yes（cat -n /usr/local/redis/bin/redis.conf | grep protected-mode）
#	   生效條件：bind被註釋掉和沒有配置訪問密碼的時候才生效
#	4：dir：指定rdb檔案路徑（在一臺伺服器上啟動多個Redis服務時，注意修改為不同檔案路徑）
#	5:從服務預設為只讀模式 replica-read-only yes
