实验环境
主节点 10.10.10.12
从节点10.10.10.11
安装Redis
wget http://download.redis.io/releases/redis-4.0.9.tar.gz 下载redis
tar -xvf redis-4.0.9.tar.gz
cd redis-4.0.9 查看已经存在makfile 文件
yum install gcc-c++
MAKE
make PREFIX=/usr/local/redis MALLOC=libc install
参数解释
PREFIX=/usr/local/redis：指定源码安装的目录
MALLOC=libc（内存碎片优化）
libc=内存管理的GNU的中一个libc组件，C语言中申请内存的关键字就是MALLOC
执行make & make install
配置主节配置文件
vim /usr/local/redis/redis.conf
修改或增加
bind 0.0.0.0
0.0.0.0 表示可以连接主机的任意地址
配置备节点文件增加
slaveof 10.0.0.6 6379
主备节点需要关闭防火墙和selinux
