python - mysql错误: ERROR 1018 (HY000): Can't read dir of '.' (errno: 13)

Question

当我尝试在 mysql 中查看数据库时，出现此错误:

ERROR 1018 (HY000): Can't read dir of '.' (errno: 13)

这会阻止我的应用显示...

我的 django 调试器说:

(2002, "Can't connect to local MySQL server through socket '/var/lib/mysql/my_database' (13)")

这是我的设置文件:

DATABASES = {
'default': {
    'ENGINE': 'django.db.backends.mysql', # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'.
    'NAME': 'my_database',                      # Or path to database file if using sqlite3.
    'USER': 'root',                      # Not used with sqlite3.
    'PASSWORD': '****',                  # Not used with sqlite3.
    'HOST': '',                      # Set to empty string for localhost. Not used with sqlite3.
    'PORT': '3306',                      # Set to empty string for default. Not used with sqlite3.

什么可能导致问题？

提前致谢

您需要为目录设置所有权和权限:

chown -R mysql:mysql /var/lib/mysql/ #your mysql user may have different name
chmod -R 755 /var/lib/mysql/

注意:-R 使命令递归 - 如果 /var/lib/mysql/ 中没有子目录，您可以省略它。
