mysql 错误:错误 1018 (HY000):无法读取 '.' 的目录(错误号:13)

mysql error : ERROR 1018 (HY000): Can#39;t read dir of #39;.#39; (errno: 13)(mysql 错误:错误 1018 (HY000):无法读取 . 的目录(错误号:13))

问题描述

当我尝试在 mysql 中查看数据库时出现此错误:

when i try to view the databases in mysql i get this error:

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

这会阻止我的应用程序显示...

And that stops my app from displaying...

我的 Django 调试器说:

My django debugger says:

(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.

导致问题的原因是什么?

What can cause the problem?

推荐答案

您需要设置目录的所有权和权限:

You need to set ownership and permissions for directory:

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.

Note: -R makes commands recursive - you may omit it, if there is no subdirs in /var/lib/mysql/.
