MysqlD 开始了吗？

[root@SSH mysql]# sudo /etc/init.d/mysqld restart 停止 mysqld：[确定] MySQL 守护程序无法启动。 启动 mysqld：[失败]

-1 表示不阅读日志：The error means mysqld does not have the access rights to the directory.

【参考方案1】：

运行 MySQL 守护程序的用户无权写入您的数据库目录。

如果您使用默认设置的标准安装，以下命令应该可以解决该问题（根据您编辑的输出编辑添加 sudo：如果您可以以 root 运行，请不要使用 sudo ):

sudo chown -R mysql:mysql /var/lib/mysql

您可以通过在/etc/my.cnf 或/etc/mysql/my.cnf 中查找user= 选项来准确找到用户（如果不是mysql）。

【讨论】：

在chown 前加上sudo。我已根据您的输出进行了编辑。

[root@SSH mysql]# sudo chown -R mysql:mysql /var/lib/mysql chown: 更改 `/var/lib/mysql/ibdata1' 的所有权：不允许操作

/var 是从网络共享安装的吗？是只读文件系统吗？

运行 mount 并查看是否出现以 /var 开头的内容以查看 /var 是否从网络共享挂载。输出还应该显示它是否以只读方式安装，因为您会在输出中看到 ro 而不是 rw。
