所有redis服务器，监听所有端口

sed -rni 's@(^bind ).*@\10.0.0.0@p' /usr/local/redis/etc/redis.conf #监听所有端口
sed  -n '/^bind/p' /usr/local/redis/etc/redis.conf                  #查看

查看角色

root@ubuntu:~# redis-cli
127.0.0.1:6379> info

从服务器配置

echo "slaveof 192.168.47.54 6379" >> /usr/local/redis/etc/redis.conf
重启服务后，master就变为了slave
systemctl restart redis

master服务器进行测试

root@ubuntu:~# redis-cli
127.0.0.1:6379> set key1 tao

127.0.0.1:6379> set key2 wen
