無法在 Arch linux 中啟動 mysqld

我最近安裝了 Arch Linux x64，我想安裝 LAMP 堆棧。一切正常，直到我到達我安裝但無法啟動的 MySQL 部分。的輸出 sudo systemctl start mysqld 給出：

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

這是systemctl status mysqld.service輸出：

* mysqld.service - MariaDB database server

找到您只需執行此命令的解決方案：

sudo mysql_install_db --user=mysql --basedir=/usr/ --ldata=/var/lib/mysql/

還要檢查您的分區是否未滿，這是我的情況。

由於未知原因，將數據移動到另一個分區也不起作用。

因此，為了快速修復，我沒有弄亂 llvm 或 gparted，而是減小了/swapfile尺寸。
