MariaDB Docker 启动失败

Question

我正在尝试使用 Docker 1.13.1 启动 MariaDB。

docker run -d --name mariadb -e MYSQL_ROOT_PASSWORD=password -p 3306:3306   -p 4567:4567/udp   -p 4567-4568:4567-4568   -p 4444:4444   -v /mnt/data/mysql:/var/lib/mysql mariadb:10.1 chown -R mysql:mysql /var/lib/mysql && mysqld --user=mysql --wsrep-new-cluster

启动后得到如下输出：

mysql 用户拥有该目录并能够创建 ibdata1 和相关文件。我不知道它是否无法创建其他表和/或为什么无法读取它们？

Answer 1

修复：

docker run -d --name mariadb -e MYSQL_ROOT_PASSWORD=password -p 3306:3306   -p 4567:4567/udp   -p 4567-4568:4567-4568   -p 4444:4444   -v /mnt/data/mysql:/var/lib/mysql mariadb:10.1 /bin/bash -c 'chown -R mysql:mysql /var/lib/mysql && mysqld --user=mysql --wsrep-new-cluster'

问题是&& 之后的所有内容都没有作为命令行插入容器内，而是在主机 shell 中插入外部，除非正确引用为 /bin/bash (/bin) 的 -c 选项的参数/sh 也是有效的）。

Answer 2

我在启动脚本中解决了这个问题，该脚本在 docker 映像中作为我的 ENTRYPOINT 的一部分运行：

chmod -R ug+rw /var/lib/mysql
chown -R mysql:mysql /var/lib/mysql
service mysql start

这样，我避免了所有的卷安装，并且可以简单地在我的普通容器中使用读写层。这是为一个开源项目构建一个开发人员容器，所以我正在尝试制作一个一体化的容器供我的开发人员使用。可能有更清洁的方法来解决这个问题 - 但这对我有用。
