错误 2002 (HY000):无法通过套接字 '/var/run/mysqld/mysqld.sock' (2) 连接到本地 MySQL 服务器
我尝试了网上找到的所有方法,但无法解决 Ubuntu 11.04 上的问题。
我尝试了以下几个步骤:
- 使用
sudo /usr/sbin/mysqld start
手动启动 mysqld - 使用
service mysqld start
启动 mysqld - 使用
ps ax | grep mysqld
检查它是否正在运行,并得到结果3419 pts/0 S+ 0:00 grep --color=auto mysqld
- 手动在
/var/run/mysqld/mysqld.sock
创建文件 - 授予
mysql
用户权限 - 尝试卸载并重新安装,但仍然无法解决问题
- 尝试使用
tasksel
配置 LAMP,其他所有内容都正常工作,但 mysql 仍然生成相同的错误
当使用 mysqld -P 3305
运行时会生成错误。

如何解决这个错误?
mysql -uroot -p
,它报错了,如果我使用命令sudo service stop mysql
,就可以正确执行。但是如果我使用命令sudo service start mysql
,它需要大约20秒钟的时间。 - Nazar Hussain
