Percona 5.6 Docker Image无法加载我的/etc/mysql/conf.d/*.cnf

我至less在这个问题上奋斗了14个小时。

我正在用CentOS 7configurationdocker，jenkins，java，scala等构build服务器。

在使用liquibase和jooq：codegen时，我需要有适当的MySQL（Percona：5.6）容器设置，但不幸的是，官方Percona Image（Percona：5.6）不会在/ etc / mysql / conf.d正确，我认为这是我的问题，如文件权限问题。

我在跟随来自Docker Hub：Percona的指示 但是这对我不起作用，我尝试了很多错误的方法，没有一个在工作。

文件/文件夹权限如下图所示：

装入容器后，如下图所示：

docker-compose.yaml如下所示：

官方Percona 5.6提供的默认my.cnf如下：

root@25295730da09:/etc/mysql# cat my.cnf # # The MySQL database server configuration file. # # You can copy this to one of: # - "/etc/mysql/my.cnf" to set global options, # - "~/.my.cnf" to set user-specific options. # # One can use all long options that the program supports. # Run program with --help to get a list of available options and with # --print-defaults to see which it would actually understand and use. # # For explanations see # http://dev.mysql.com/doc/mysql/en/server-system-variables.html # This will be passed to all mysql clients # It has been reported that passwords should be enclosed with ticks/quotes # escpecially if they contain "#" chars... # Remember to edit /etc/mysql/debian.cnf when changing the socket location.

Answer 1

原因是因为目录：/etc/mysql/conf.d应该至less有555个权限。

问题解决了。
