实操过程

	6379(Master)	6380(Master)	6381(Master)	6382(Slave)	6383(Slave)	6384(Slave)
	Centos7.4 redis 4.0.14
安装redis	# yum install gcc gcc-c++ # useradd redis # echo "Redis123" \|passwd --stdin redis # su - redis # 以下所有的操作全部都在redis用户下执行 $ wget http://download.redis.io/releases/redis-4.0.14.tar.gz $ tar -zxf redis-4.0.14.tar.gz $ mkdir -p /home/redis/redis4.0#创建 redis 安装目录 $ cd redis-4.0.14 $ make $ make PREFIX=/home/redis/redis4.0 install#安装到~/redis4.0目录 $ export PATH=$PATH:$HOME/redis4.0/bin #安装完成 $ mkdir /home/redis/{redis_6379,redis_6380,redis_6381,redis_6382,redis_6383,redis_6384}#创建redis工作目录
