Redis 集群-主从复制（基于Docker Compose）

Compose 是用于定义和运行多容器 Docker 应用程序的工具。通过 Compose，您可以使用 YML 文件来配置应用程序需要的所有服务。然后，使用一个命令，就可以从 YML 文件配置中创建并启动所有服务。

Redis 主从复制

一个主数据库可以拥有多个从数据库，而一个从数据库只能拥有一个主数据库。Master不管Slave， Slave去找Master，Slave与Slave之间是无法进行通讯的。

Redis Master 读写
Redis Slave 只读
Redis Slave 只读

同步的工作方式如下：

​ 主机启动后台保存过程以生成RDB文件。同时，它开始缓冲从客户端收到的所有新写命令。后台保存完成后，主数据库将数据库文件传输到从数据库，从数据库将其保存在磁盘上，然后将其加载到内存中。然后，主服务器将所有缓冲的命令发送到副本。这是作为命令流完成的，并且与Redis协议本身的格式相同。

1.创建文件夹，进入该文件夹

# 创建文件夹
$ mkdir -p docker/redis/#进入文件夹
$ cd docker/redis/

2.创建docker-compose.yml文件
也可直接下载我写好的docker-compose.yml文件

$ vim docker-compose.yml

docker-compose.yml内容如下：

# 撰写规范
version: '3.8'# 定义容器
services:# 名称redis_master:# 镜像名称image: redis# 容器名称container_name: redis_master# 跟随容器启动restart: always# 环境变量environment:- "TZ=Asia/Shanghai"# 端口映射 主机端口:容器端口ports:- "6379:6379"# 启动后默认执行命令# 设置密码 --requirepass 123456command:redis-server --requirepass 123456# 名称redis_slave_1:# 镜像名称image: redis# 容器名称container_name: redis_slave_1# 跟随容器启动restart: always# 环境变量environment:- "TZ=Asia/Shanghai"# 端口映射 主机端口:容器端口ports:- "6380:6379"# 启动后默认执行命令# 将当前服务器转变为指定服务器的从属服务器 --slaveof host port# 设置密码 --requirepass 123456# Master服务器密码 --masterauth 123456command:redis-server --slaveof redis_master 6379 --requirepass 123456 --masterauth 123456# 名称redis_slave_2:# 镜像名称image: redis# 容器名称container_name: redis_slave_2# 跟随容器启动restart: always# 环境变量environment:- "TZ=Asia/Shanghai"# 端口映射 主机端口:容器端口ports:- "6381:6379"# 启动后默认执行命令# 将当前服务器转变为指定服务器的从属服务器 --slaveof host port# 设置密码 --requirepass 123456# Master服务器密码 --masterauth 123456command:redis-server --slaveof redis_master 6379 --requirepass 123456 --masterauth 123456

docker-compose.yml撰写规范(version)是根据docker版本不同，而有所不同的。

$ sudo docker --version
Docker version 19.03.8, build afacb8b7f0

以下是对应关系：撰写文件版本和升级

Compose file format Docker Engine release
Compose specification 19.03.0+
3.8 19.03.0+
3.7 18.06.0+
3.6 18.02.0+
3.5 17.12.0+
3.4 17.09.0+
3.3 17.06.0+
3.2 17.04.0+
3.1 1.13.1+
3.0 1.13.0+
2.4 17.12.0+
2.3 17.06.0+
2.2 1.13.0+
2.1 1.12.0+
2.0 1.10.0+
1.0 1.9.1.+

3.docker-compose.yml启动管理的容器

$ sudo docker-compose up -d Creating network "redis_default" with the default driver
Creating redis_slave_2 ... done
Creating redis_slave_1 ... done
Creating redis_master  ... done

4.查看由docker-compose管理的容器

$ sudo docker-compose psName                   Command               State           Ports
-------------------------------------------------------------------------------
redis_master    docker-entrypoint.sh redis ...   Up      0.0.0.0:6379->6379/tcp
redis_slave_1   docker-entrypoint.sh redis ...   Up      0.0.0.0:6380->6379/tcp
redis_slave_2   docker-entrypoint.sh redis ...   Up      0.0.0.0:6381->6379/tcp

5.查看容器运行状态

$ sudo docker psCONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
9af1bfa762ce        redis               "docker-entrypoint.s…"   16 seconds ago      Up 14 seconds       0.0.0.0:6379->6379/tcp   redis_master
dc9280698682        redis               "docker-entrypoint.s…"   16 seconds ago      Up 14 seconds       0.0.0.0:6380->6379/tcp   redis_slave_1
d9a9a2aa0dd3        redis               "docker-entrypoint.s…"   16 seconds ago      Up 14 seconds       0.0.0.0:6381->6379/tcp   redis_slave_2

6.进入容器redis_master，查看主从复制状态

$ sudo docker exec -it 9af1bfa762ce bashroot@9af1bfa762ce:/data# redis-cli
127.0.0.1:6379> auth 123456
OK
127.0.0.1:6379> info replication
# Replication
role:master
connected_slaves:2
slave0:ip=172.19.0.2,port=6379,state=online,offset=112,lag=0
slave1:ip=172.19.0.3,port=6379,state=online,offset=112,lag=0
master_replid:0031d2325bc01f3e25c6a962c1abb14655dcf3e3
master_replid2:0000000000000000000000000000000000000000
master_repl_offset:112
second_repl_offset:-1
repl_backlog_active:1
repl_backlog_size:1048576
repl_backlog_first_byte_offset:1
repl_backlog_histlen:112
127.0.0.1:6379> exit
root@9af1bfa762ce:/data# exit
exit
  • redis-cli：进入redis。
  • auth "123456"：密码登录
  • info replication：查看主从复制信息。

在此处我们可以看到connected_slaves:2，这意味着有两台从机连接。slave0和slave1便是两台从机的信息。

7.关闭并删除容器

$ sudo docker-compose downStopping redis_master  ... done
Stopping redis_slave_2 ... done
Stopping redis_slave_1 ... done
Removing redis_master  ... done
Removing redis_slave_2 ... done
Removing redis_slave_1 ... done
Removing network redis_default
