这个警告消息表示 MySQL 配置文件 `/etc/mysql/my.cnf` 是可写的,这可能会导致潜在的安全问题。在 MySQL 启动时,它会忽略这个文件以保证安全性。
为了解决这个问题,你需要使 `/etc/mysql/my.cnf` 文件不可写。你可以使用以下命令来更改文件权限:
```
sudo chmod 644 /etc/mysql/my.cnf
```
这将把文件权限修改为 `-rw-r--r--`,其中所有者具有读写权限,而组和其他用户只有读权限。这将确保 MySQL 可以读取配置文件,同时保护文件不被任意修改。

mysqladmin: [Warning] World-writable config file '/etc/mysql/my.cnf' is ignored. mysqladmin: connect to server at 'localhost' failed error: 'Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)' Check that mysqld is running and that the socket: '/var/run/mysqld/mysqld.sock' exists!怎么解决
这个错误提示表明mysqladmin无法通过Unix Socket连接到MySQL服务器,可能是由于MySQL服务器未运行或Unix Socket文件不存在。
您可以尝试以下步骤来解决这个问题:
1. 检查MySQL服务是否正在运行:使用以下命令检查MySQL服务的状态:
```
sudo service mysql status
```
如果MySQL服务未运行,请使用以下命令启动它:
```
sudo service mysql start
```
2. 检查Unix Socket文件是否存在:使用以下命令检查Unix Socket文件是否存在:
```
ls -l /var/run/mysqld/mysqld.sock
```
如果文件不存在,请使用以下命令创建它:
```
sudo touch /var/run/mysqld/mysqld.sock
sudo chown mysql:mysql /var/run/mysqld/mysqld.sock
```
3. 确认MySQL配置文件权限正确:使用以下命令检查MySQL配置文件权限:
```
ls -l /etc/mysql/my.cnf
```
确认MySQL配置文件的权限为644,即:
```
-rw-r--r-- 1 root root 3126 Oct 2 16:42 /etc/mysql/my.cnf
```
如果权限不正确,请使用以下命令更改它:
```
sudo chmod 644 /etc/mysql/my.cnf
```
如果以上步骤仍无法解决问题,请检查MySQL错误日志以获取更多信息,并根据错误日志中的指示进行故障排除。

这个错误是因为MySQL服务器无法切换到exporter用户。这可能是由于以下原因之一:
1. 用户exporter不存在。请确保您已经创建了一个名为exporter的用户,并且该用户存在于系统中。
2. 您没有足够的权限切换到exporter用户。请确保您有足够的权限以exporter用户身份运行mysqld进程。
您可以尝试使用以下命令解决此问题:
1. 检查exporter用户是否存在。如果不存在,请使用以下命令创建一个新用户:
```
sudo adduser exporter
```
2. 将exporter用户添加到mysql用户组中,以便它可以访问MySQL文件和目录:
```
sudo usermod -aG mysql exporter
```
3. 确保exporter用户拥有MySQL数据目录的所有权:
```
sudo chown -R mysql:mysql /var/lib/mysql/
```
4. 尝试使用以下命令以exporter用户身份启动MySQL服务器:
```
sudo -u exporter mysqld --default-authentication-plugin=mysql_native_password
```
如果这些步骤没有解决问题,请提供更多详细信息,例如您是如何创建exporter用户的,以及您运行mysqld命令的完整命令行。
