我只是在一台干净的Debian 7机器上安装MariaDB。 当我想运行mysql_install_db ，我得到这样一组错误：

我看着错误11，这意味着根据MySQL 5.6文档“EAGAIN”。 我不知道为什么MariaDB没有解释这个问题，因为我不知道下一步该怎么做。 谁帮我出去？
MariaDB已经在运行 （因为Debian启动了它并为你运行了mysql_install_db ）。
我脑海中出现了两种问题：
还有另一个mysqld运行的实例。
用ps -ef | grep mysqld检查 ps -ef | grep mysqld
您有权限问题。 您的用户没有权限写入数据库文件。 检查./ibdata1文件的权限。
