我刚刚在一台干净的 Debian 7 机器上安装了 MariaDB。当我想要运行时mysql_install_db，我收到以下错误：

If you tried to add new data files to the system tablespace, and it failed here, you should now edit innodb_data_file_path in my.cnf back to what it was, and remove the new ibdata files InnoDB created in this failed attempt. InnoDB only wrote those files full of zeros, but did not yet use them in any way. But be careful: do not remove old data files which contain your precious data!

我查看了错误 11，根据 MySQL 5.6 文档，它表示“EAGAIN”。我不确定为什么 MariaDB 没有解释这一点，因为我不知道下一步该怎么做。谁能帮帮我？
答案1
MariaDB 已在运行（因为 Debian 为您启动并运行了mysql_install_db它）。
答案2
我想到两种问题：
还有另一个 mysqld 实例正在运行。
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。请检查
./ibdata1文件的权限。
