Docker搭建Redis主从实现读写分离

Docker搭建Redis主从实现读写分离

先去服务器宿主机任意目录创建如下目录  建议弄个文件夹专门放挂载数据的目录

每个文件夹内部都创建如下目录 

conf放f 文件

data挂载redis数据

logs挂载日志

配置防火墙和安全组 开启这些对应的端口号

 主机master  conf配置

requirepass password  需要的登录密码
masterauth password  配置哨兵的话主机也需要这个 建议所有主从机密码都一致或者不配置密码

这两个全部写一个密码或者都不配置

建议实际开发不配置密码 通过bind设置指定ip和安全组防火墙来设置登录

# bind 192.168.1.100 10.0.0.1   记得注释掉
# bind 127.0.0.1 ::1                    记得注释掉

docker部署主机master 

docker run -it -p 7011:6379 -p 26379:26379
--name docker-redis-master
--privileged=true
--restart=always
-v /usr/local/app/redis/7011/f:/etc/f
-v /usr/local/app/redis/7011/data:/data
-v /etc/localtime:/etc/localtime
-e TZ="Asia/Shanghai"
-d redis redis-server /etc/f

docker部署从机slave  部署两个  注意修改下端口号映射  挂载目录即可

从机2 slave
docker run -it -p 7013:6379 -p 26381:26379
--name docker-redis-slave2
--privileged=true
--restart=always
-v /usr/local/app/redis/7013/f:/etc/f
-v /usr/local/app/redis/7013/data:/data
-v /etc/localtime:/etc/localtime
-e TZ="Asia/Shanghai"
-d redis redis-server /etc/f 

查看容器

登录主机 redis-cli  然后输入auth 密码 

info replication  查看集群状态 可以看到这个容器是master主机 连接上了两个slave从机

再切换到slave从机 输入info replication 可以看到连接到了主机

 ​​​​​​

从机只可以读取 不可以写入

 主机可以读写
