问豆包：
从你提供的新日志信息可知，MySQL 启动失败是由于无法设置 Unix 套接字锁文件，具体错误信息为 Unix socket lock file is empty /tmp/mysql.sock.lock 和 Unable to setup unix socket lock file。下面为你提供几种可能的解决办法：
1. 检查套接字文件和锁文件权限
Unix 套接字文件和锁文件的权限可能不正确，从而导致 MySQL 无法对其进行操作。你可以通过以下命令检查并修改权限：
| # 检查文件权限 | |
| ls -l /tmp/mysql.sock.lock | |
| ls -l /tmp/mysql.sock | |
| # 修改权限 | |
| sudo chmod 660 /tmp/mysql.sock.lock | |
| sudo chmod 660 /tmp/mysql.sock | |
| # 修改文件所有者 | |
| sudo chown mysql:mysql /tmp/mysql.sock.lock | |
| sudo chown mysql:mysql /tmp/mysql.sock |
2. 删除套接字文件和锁文件并重启服务
有时，套接字文件和锁文件可能已损坏。你可以将其删除，然后尝试重新启动 MySQL 服务：
| sudo rm -f /tmp/mysql.sock.lock | |
| sudo rm -f /tmp/mysql.sock | |
| sudo systemctl restart mysql |
4. 检查配置文件
确保 MySQL 配置文件（通常是 /etc/mysql/my.cnf 或 /etc/my.cnf）中的套接字路径配置正确。查找配置文件中的 socket 参数，确保其指向正确的路径：
| [mysqld] | |
| socket = /tmp/mysql.sock |
最终直接删除了mysql.sock.lock 后启动成功，问题解决。
