无法在 arch linux 中启动 mysqld

Question

我最近安装了 Arch Linux x64，我想安装 LAMP 堆栈。一切正常，直到我到达我安装但无法启动的 MySQL 部分。的输出 sudo systemctl start mysqld 给出：

Job for mysqld.service failed because a timeout was exceeded. See "systemctl status mysqld.service" and "journalctl -xe" for details.

这是systemctl status mysqld.service输出：
