mysql的docker化安装

mysql版本有很多，先看下各类版本号说明：

3.X至5.1.X：这是早期MySQL的版本。常见早期的版本有：4.1.7、5.0.56等。

5.4.X到5.7.X：这是为了整合MySQL AB公司社区和第三方公司开发的新存储引擎。吸收新的实现算法，更好的支持SMP架构。为提升性能做了大量代码重构。

6.0.X到7.1.X：这是为了更好推广MySQL Cluster版本，以及提高MySQL性能和稳定性以及新功能。改动MySQL基础功能，从而对Cluster存储引擎提供更有效支持优化。因为发布时间较晚，发布时已经有其他手段解决MySQL集群技术问题，所以并没有很好的推广使用。

看了版本说明就很好选择想要使用的版本了，由于笔者常用的是5.7.13版本，此处就以此为例，步骤就是先查寻并获取镜像（此处略）。

镜像获取完成后启动mysql，到容器里面看下配置文件my.conf：

[root@devlop ~]# sudo docker exec -it mysql bash
root@b60ba70e2447:/# cat /etc/mysql/
conf.d/ my.cnf  
root@b60ba70e2447:/# cat /etc/mysql/my.cnf

!includedir /etc/mysql/conf.d/
root@b60ba70e2447:/# 

看到配置后，就可以把自己想要的目录持久化出来了，且注意时区转换：

docker run --name mysqltest -p 3306:3306 -v /usr/share/zoneinfo/Asia/Shanghai:/etc/localtime -v /data/mysql:/var/lib/mysql -eMYSQL_ROOT_PASSWORD=root-password -d mysql:5.7.13

启动完成后进入容器连一下mysql，并看看时区：

[root@devlop ~]# docker exec -it mysqltest bash
root@5446ce5c7ddf:/# mysql -p
Enter password:
