引用:这边讲述了mysql提供的“mysql”、“mysqldump”、“mysqladmin”等命令提示“ERROR 2002 (HY000): Can't connect to local MySQL server through socket '***' (2)”的解决方法，如果需要解决“php”、“perl”、“python”等脚本语言提示此错误的问题。

根据引用内容，当执行mysql命令时出现"ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)"的错误信息，通常表示无法通过socket连接到本地的MySQL服务器。

解决这个问题可以尝试以下步骤：
1. 确保MySQL服务器正在运行。可以使用命令"service mysql status"来检查MySQL服务器的运行状态。
2. 检查MySQL服务器的配置文件。可以通过编辑/etc/mysql/my.cnf文件来查看配置信息，确保该文件中的socket路径与错误信息中显示的路径一致。
3. 检查/var/lib/mysql目录中是否存在mysql.sock文件。如果不存在，可以尝试执行以下命令来重新创建该文件：
- sudo mkdir /var/lib/mysql
- sudo touch /var/lib/mysql/mysql.sock
- sudo chown -R mysql:mysql /var/lib/mysql
- sudo service mysql restart
4. 如果以上步骤都没有解决问题，可以尝试重新安装MySQL服务器或者联系系统管理员或MySQL的技术支持了解更详细的解决方法。

请注意，以上步骤仅为常见解决方法之一，具体的解决方法可能因系统环境和配置而异。建议在操作前备份重要数据，并谨慎进行操作。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
