Docker搭建mysql和Redis开发环境

查看docker mysql镜像信息

查看mysql镜像的ip

docker exec chai_mysql cat /etc/hosts

进入mysql镜像命令行

docker exec -it chai_mysql bash

docker run my_mysql找不到container的问题，要用start命令

docker start my_mysql

问题

1. redis容器中的redis.conf访问被拒

sudo docker run -it -v /home/Me/docker/chai/redis-master.conf:/usr/local/etc/redis/redis.conf --name redis-master redis /bin/bash
  
redis-server /usr/local/etc/redis/redis.conf

2. Fatal error, can’t open config file ‘/usr/local/etc/redis/redis.conf

sudo docker ps

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                               NAMES
ac746d069659        redis               "docker-entrypoint..."   8 minutes ago       Up 6 minutes        6379/tcp                            redis-master

docker logs redis-master
systemctl status -l docker.service

3. SELinux is preventing /usr/local/bin/redis-server from read access on the file redis-master.conf

都是SELinux搞的鬼，编辑/etc/sysconfig/selinux 将selinux设置为disabled之后重启就可以了。

4. error creating overlay mount to /var/lib/docker/overlay2/

重新建立mysql和docker容器

上面的解决方案中清理掉了所有的docker镜像和容器

docker pull mysql
sudo docker run --name chai_mysql -p 3306:3306 MYSQL_ROOT_PASSWORD=12345 -d mysql

docker pull redis

master

sudo docker run -it -v /home/Me/docker/chai/redis-master.conf:/usr/local/etc/redis/redis.conf --name redis-master redis /bin/bash

slave

sudo docker run -it -v /home/Me/docker/chai/redis-slave.conf:/usr/local/etc/redis/redis.conf --link redis-master:master --name redis-slave redis /bin/bash

设置开机启动

docker update --restart=always redis-master

注意

1. 确保master的bind是0.0.0.0
2. 确保slave要link master:master
