linux上一键安装redis以及主从配置（脚本自动安装）

一、环境配置
    1：任何位置创建文件夹
       mkdir redis;cd  redis;mkdir conf;cd conf
       #下载安装安装包
       wget http://www.redis.cn/download.html/redis-5.0.3.tar.gz
    2:书写自动安装redis的脚本和自动安装主从
       cd ..
       vim install.sh
    3:在conf目录中再编写启动脚本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

#启动和关闭脚本
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

##让redis可以后台启动
AA=`cat -n redis.conf  | grep daemonize | grep -v "#" | awk '{print $1}'`
sed -i ''"$AA"'c  daemonize yes'   redis.conf

#开机自启：
echo  "/usr/local/redis/bin/redis-server /usr/local/redis/bin/redis-conf"  >> /etc/rc.local

#创建登录数据库的命令
cp /usr/local/redis/bin/redis-cli /usr/bin/

clear
echo "启动 redis start "
echo "关闭 redis stop "
echo "重启 redis restart"
}


#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~主从搭建~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#注意事项：
#    1：主从模式时matser节点开启持久化（不开的话，matser节点重启，从会出现丢失数据）
#	2：先开启主机上的服务，后开机从机上的服务
#	3：默认是开启保护模式protected-mode yes（cat -n /usr/local/redis/bin/redis.conf | grep protected-mode）
#	   生效条件：bind被注释掉和没有配置访问密码的时候才生效
#	4：dir：指定rdb文件路径（在一台服务器上启动多个Redis服务时，注意修改为不同文件路径）
#	5:从服务默认为只读模式 replica-read-only yes
