无法在 Ubuntu 中运行 mysqld

我尝试运行 mysqld 但在 Ubuntu 终端中出现以下错误。

2022-08-30T18:48:34.596763Z 0 [Warning] [MY-010091] [Server] Can't create test file /var/lib/mysql/mysqld_tmp_file_case_insensitive_test.lower-test

当我尝试/var/lib/mysql通过以下方式更改路径权限时sudo chown -R mysql /var/lib/mysql出现错误：

chown: invalid user: ‘mysql’

我正在尝试学习 Ubuntu/Linux，因此这是我在这个系统中迈出的第一步。

尝试以 root 身份运行命令（使用sudo）

sudo systemctl start mysql

为了确认它已经开始，请尝试运行

sudo systemctl status mysql
