Question

我通过查杀进程id来停止mysqld，然后还删除了mysqld.sock文件。现在，mysqld没有启动。

我知道有一些数据损坏。但现在我需要启动MySQL而不重新安装它。

以下是生成的日志。

您需要恢复innodb数据文件。

# cd /var/lib/mysql
# mkdir bak
# mv ibdata1 bak/
# mv ib_logfile* bak/
# cp -a bak/ibdata1 ibdata1
# cp -a bak/ib_logfile* .
# rm -rf bak
# service mysqld restart

哇。我有这个问题，因为那是一个清晨，我的大脑不起作用。我正在做以下事情：

 sudo mysqld -u root -p

当我应该这样做的时候：

 sudo mysql -u root -p

希望这可以帮助像我这样早安的人。哈哈

不正当杀害mysqld - 现在没有开始
