转载：https://www.cnblogs.com/yanyanqaq/p/12695598.html

1.环境规划

主机名	角色	IP地址
db01	Redis master	172.16.1.51
db02	Redis slave	172.16.1.52
db03	Redis slave	172.16.1.53

cd /soft/

wget http://download.redis.io/releases/redis-3.2.12.tar.gz

2.Redis安装并添加配置文件

tar xzf redis-3.2.12.tar.gz
mv redis-3.2.12 /etc/redis
cd /etc/redis
make

vim /etc/redis/redis.conf
daemonize yes
port 6379
dbfilename dump.rdb
protected-mode no
save 900 1
save 300 10
save 60 10000

3.启动Redis服务

redis-server  /etc/redis/redis.conf &

4.在从库上开启主从

redis-cli
127.0.0.1:6379> SLAVEOF 172.16.1.51 6379
set get delete

5.在从库上检查主从复制的状态

redis-cli
127.0.0.1:6379> info replication

6.在主库上检查主从复制的状态

redis-cli
127.0.0.1:6379> info replication

7.添加环境变量

vim /etc/profile
export PATH=/etc/redis/src:$PATH

source /etc/profile
