我在Ubuntu 12.04 LTS (Precise穿山甲)上安装了LAMP,然后在phpMyAdmin上设置根密码。我忘记密码了,现在无法登录。当我试图通过终端更改密码时,我得到:

错误2002 (HY000):无法通过套接字连接到本地MySQL服务器 ' / var /运行/ mysqld / mysqld。袜子”(2)

我该如何解决这个问题?我无法打开LAMP,卸载它或重新安装它。

在/etc/mysql/my.cnf中,检查最后一行是:

!includedir /etc/mysql/conf.d/

其他回答

对我来说是:

打开/etc/mysql/my.cnf或/etc/my.cnf,搜索“bind-address”。结果是127.0.0.1。我将其转换为localhost,因此行结果应该是'bind-address = localhost'。

否则,你应该使用bind-address指令中存在的IP地址运行你的MySQL服务器,即MySQL -h 127.0.0.1。

您可以查看/var/log/mysql.log日志

对我来说,这不是工作的BCS的错误:

无法为缓冲池错误分配内存

我在/etc/my.cnf中添加了这一行,并启动了服务:

通过innodb_buffer_pool_size = 100

您缺少创建/var/run/mysqld目录的权限。所以请创建和 给予许可如下。

Mkdir -p /var/run/mysqld Chown mysql:mysql /var/run/mysqld

This error can also occur if you try to change the directory where the database is stored, but imput the wrong directory in the configuration file (like a typo in the second drive as D instead of the accurate D_). Instead of telling you the typo directory does not exist, it will tell you that you lack permission to access it (leading you to try to change the permissions for the typo directory, which it will let you do). So if you get this error while changing directories, double check the configuration file and make sure you don't have a typo.

我通过在mysqld部分([mysqld])中删除/etc/mysql/my.conf中的这一行来解决这个问题:

default-character-set=utf8

重新启动,它可以正常工作。
