ERROR 2002 (HY000): 无法通过套接字 '/var/run/mysqld/mysqld.sock' 连接到本地 MySQL 服务器 (2)

我尝试了在互联网上找到的所有内容，但无法解决 Ubuntu 11.04 上的问题。

我尝试了这些事情：

  • 使用手动启动 mysqldsudo /usr/sbin/mysqld start
  • 使用 mysqld 启动service mysqld start
  • 检查它正在运行ps ax | grep mysqld并得到结果3419 pts/0 S+ 0:00 grep --color=auto mysqld
  • 手动创建文件/var/run/mysqld/mysqld.sock
  • 赋予mysql用户权限
  • 试图删除并重新安装，但它仍然无法正常工作
  • 尝试tasksel配置 LAMP，其他一切正常，但 mysql 产生相同的错误。

使用它运行时mysqld -P 3305会产生错误

我做了实验，最后用这些命令解决了

sudo chown mysql:root /var/lib/mysql/ -R
sudo chmod g+rw /var/lib/mysql/ -R
sudo /usr/sbin/mysqld --skip-grant &

它开始运行...... Hurraaahhhhhhhhhh !!!!!!!!!!!!

您的日志实际上告诉您问题：

mysqld：参数太多（第一个额外是“开​​始”）。

只需启动不带“开始”一词的守护程序。代替：

sudo /usr/sbin/mysqld 开始

它应该只是：

须藤/usr/sbin/mysqld

如果您安装了多个 mysql 服务器，请确保运行正确的 MYSQL 或更改路径设置。例如：

/opt/lampp/bin/mysql -u root -p

我安装了 XAMPP，该解决方案对我有用。

看起来它无法在 /var/lib/mysql/ 中创建文件。如果您查看errode 13，则通常表示权限错误。

1) 确保 mySQL 可以写入目录 /var/lib/mysql 和/或 mySQL 拥有该目录。做一个：

cd /var/lib ; ls -la | grep mysql

为了确定。

2) 如果您尝试以 mySQL 用户启动，请改用 root 启动它（您可能是，但值得检查）。

3) 如果您正在运行 SElinux 之类的东西，请确保启用它以进行 mySQL 访问。我怀疑情况是否如此，但值得检查。

4) 小提示：不要创建 sock 文件——一旦启动并正常运行，mysql 就会创建一个。如果它仍在运行目录中，请将其删除。

尝试使用终止套接字（这可能取决于您的操作系统）

rm /var/lib/mysql/mysql.sock rm：删除套接字`/var/lib/mysql/mysql.sock'？y 重启服务

服务 mysqld 启动

你有没有尝试过？

sudo touch /etc/apparmor.d/local/usr.sbin.mysqld
