# 构建 mariadb 镜像
|
||||
|
||||
## 定制
|
||||
- 安装 mariadb
|
||||
- 固定一些常用配置
|
||||
- 第一次启动 mysql 时，会执行如下操作
|
||||
- 初始化数据目录后
|
||||
- 自动创建一个只有 shutdown 权限的普通用户，该用户用于优雅停止 mysql，__不要修改该用户任何信息__
|
||||
- 自动执行 {mysql-log}/init_sql/ 下的 xxxx.sql 文件
|
||||
|
||||
## 外挂目录和文件
|
||||
- /etc/my.cnf: mysql 配置文件
|
||||
- /var/lib/mysql: mysql 数据目录
|
||||
- /var/lib/mysql-bin: mysql binlog 目录
|
||||
- /var/log/mysql: mysql 日志目录
|
||||
|
||||
## 案例
|
||||
- [Demo/SingleNode/](Demo/SingleNode/): 部署 mariadb 单点
