mysql启动服务报错The server quit without updating PID file (/usr/local/mysql/data/kylin-KF660.pid)

这个错误通常是由于MySQL启动服务时没有写入PID文件导致的。你可以尝试以下方法解决该问题：

1. 检查MySQL配置文件my.cnf是否正确配置，特别是datadir参数是否正确指向MySQL数据目录，如果不正确，修改my.cnf文件并重启MySQL服务。

2. 检查MySQL数据目录权限是否正确，确保MySQL用户有读写权限，可以使用chmod命令修改权限。

3. 删除MySQL数据目录下的PID文件，然后重启MySQL服务，命令如下：

   sudo rm /usr/local/mysql/data/kylin-KF660.pid
   sudo service mysql restart

希望这些方法能够帮助你解决问题。

启动mysql 报错The server quit without updating PID file (/var/lib/mysql/master.pid).

启动 MySQL 时出现 "The server quit without updating PID file (/var/lib/mysql/master.pid)" 错误通常是由于权限问题或配置文件错误引起的。以下是解决此问题的一些常见方法：

1. 检查目录权限：确保 `/var/lib/mysql/` 目录及其父级目录具有适当的权限。您可以使用以下命令更改目录权限：

   sudo chmod -R 755 /var/lib/mysql/

2. 检查配置文件：打开 MySQL 配置文件（通常位于 `/etc/mysql/my.cnf` 或 `/etc/my.cnf`）并检查 `pid-file` 参数的值是否为 `/var/lib/mysql/master.pid`。确保该文件的路径和名称与配置文件中的设置相匹配。

3. 检查日志文件：检查 MySQL 日志文件（通常位于 `/var/log/mysql/error.log` 或 `/var/log/mariadb/mariadb.log`）以获取更多详细的错误信息。根据日志中的内容，您可能需要采取其他措施来解决特定的问题。

4. 删除旧的 PID 文件：如果您确定 MySQL 已经停止运行，可以尝试删除旧的 PID 文件并重新启动 MySQL。使用以下命令删除 PID 文件：

   sudo rm /var/lib/mysql/master.pid

然后尝试启动 MySQL：

   sudo service mysql start

Starting MySQL . ERROR! The server quit without updating PID file (/usr/local/mysql/data/macdeMacBook-Pro.local.pid).

It seems that you are facing an issue while starting MySQL. The error message suggests that the server quit without updating the PID file. This can happen due to various reasons, such as improper shutdown of the server or permission issues with the PID file.

To resolve this issue, you can try the following steps:

1. Check the permissions of the PID file: Ensure that the user running MySQL has the necessary permissions to read and write to the PID file. You can use the `ls -l` command to check the permissions and make any necessary changes using the `chmod` command.

2. Remove the existing PID file: If the PID file exists but is not being updated, you can try removing it. Run the following command to remove the PID file:

   sudo rm /usr/local/mysql/data/macdeMacBook-Pro.local.pid

3. Start MySQL again: After removing the PID file, try starting MySQL again. Depending on your setup, you can use commands like `sudo service mysql start` or `/usr/local/mysql/bin/mysqld_safe` to start the server.

If the issue persists, it might be helpful to check the MySQL error logs for more information about the error. The logs are usually located in the MySQL data directory or specified in the MySQL configuration file (my.cnf).
