Redis搭建主从

Redis搭建主从:

1:拉取Redis镜像

docker pull redis
1

2:创建主从对应的目录结构

3:对redis6379.log,redis6380.log,redis6381.log进行授权

chmod 777 redis6379.log
chmod 777 redis6380.log
chmod 777 redis6381.log
1
2
3

4:修改主(master)的配置文件

5:创建主(master) redis_6379

docker run -it \
--name redis_6379 \
--privileged \
-p 6379:6379 \
--network wn_docker_net \
--ip 172.18.12.10 \
--sysctl net.core.somaxconn=1024 \
-e TIME_ZONE="Asia/Shanghai" -e TZ="Asia/Shanghai" \
-v /usr/local/software/redis/6379/conf/redis6379.conf:/usr/local/etc/redis/redis.conf \
-v /usr/local/software/redis/6379/data/:/data \
-v /usr/local/software/redis/6379/log/redis6379.log:/var/log/redis.log \
-d redis \
/usr/local/etc/redis/redis.conf

6:进入 主 (master)redis_6379;并测试

docker exec -it redis_6379 bash
redis-cli
info replication

docker exec -it redis_6379 bash
redis-cli

7:用redis桌面工具连接redis_6379;并获取上一步所存的键值

8:修改从(slave)的配置文件

9:创建从(slave) redis_6380

docker run -it \
--name redis_6380 \
--privileged \
-p 6380:6379 \
--network wn_docker_net \
--ip 172.18.12.11 \
--sysctl net.core.somaxconn=1024 \
-e TIME_ZONE="Asia/Shanghai" -e TZ="Asia/Shanghai" \
-v /usr/local/software/redis/6380/conf/redis6380.conf:/usr/local/etc/redis/redis.conf \
-v /usr/local/software/redis/6380/data/:/data \
-v /usr/local/software/redis/6380/log/redis6380.log:/var/log/redis.log \
-d redis \
/usr/local/etc/redis/redis.conf

10:进入 主从(slave)redis_6380;并测试

docker exec -it redis_6380 bash
redis-cli
info replication

11:用redis桌面工具连接redis_6380;并获取在主(master)中所存的键值

12:创建从(slave) redis_6381

按照创建 redis_6380 的步骤创建即可.

docker run -it \
--name redis_6381 \
--privileged \
-p 6381:6379 \
--network wn_docker_net \
--ip 172.18.12.12 \
--sysctl net.core.somaxconn=1024 \
-e TIME_ZONE="Asia/Shanghai" -e TZ="Asia/Shanghai" \
-v /usr/local/software/redis/6381/conf/redis6381.conf:/usr/local/etc/redis/redis.conf \
-v /usr/local/software/redis/6381/data/:/data \
-v /usr/local/software/redis/6381/log/redis6381.log:/var/log/redis.log \
-d redis \
/usr/local/etc/redis/redis.conf

13:开放端口的步骤

1. firewall-cmd --add-port=3312/tcp --permanent 
   1

2. firewall-cmd --reload
   1

3. firewall-cmd --list-ports 
   1
