redis-读写分离-一台linux上模拟多台redis

在根目录创建一个文件夹

mkdir myredis
1

将原来运行的redis配置文件复制到此处一份

cp /etc/redis.conf /myredis/redis.conf
1

创建子配置运行文件

vi redis6379.config
1

redis6379.config详细

include /myredis/redis.conf
pidfile /var/run/redis_6379.pid
port 6379
dbfilename dump6379.rdb

以相同方式创建redis6380.conf redis6381.conf
运行三台redis（一主二从）

redis-server redis6379.conf
redis-server redis6380.conf
redis-server redis6381.conf
1

进入redis

[root@bogon myredis]# redis-cli -p 6379
127.0.0.1:6379> info replication //查看信息
# Replication
role:master

进入6380/6381设置主服务器

127.0.0.1:6380> SLAVEOF 127.0.0.1 6379
127.0.0.1:6381> SLAVEOF 127.0.0.1 6379

查看从服务器info

127.0.0.1:6380> info replication
# Replication
role:slave
master_host:127.0.0.1
master_port:6379
master_link_status:up

通过在服务器上查看管道符查看redis的运行状态

[root@bogon myredis]# ps -ef | grep redis
root      12823      1  0 21:37 ?        00:00:01 redis-server 0.0.0.0:6380
