我正在尝试使用该命令启动 mysql 服务器
sudo /etc/init.d/mysql start
但它不会开始。我没有得到一个特定的错误，我看到的是
* Starting MySQL database server mysqld [fail]
我尝试了相同的命令，但使用了restart相同的结果。我也试过用
sudo service start mysql
我被困在这一点上。如果我能提供更多信息，请告诉我。
谢谢你。
这是我的 mysql error.log

我知道这个问题很久以前就发布了。但是我已经找到了解决方案，因为我遇到了同样的问题。由于在操作系统中多次安装 MySQL，可能会发生此错误。
sudo ps -A|grep mysql
杀死进程 mysql
sudo pkill mysql
然后运行命令
sudo ps -A|grep mysqld
杀死进程 mysqld
sudo pkill mysqld
现在您可以安全地重新启动 MySQL 服务器了
sudo service mysql restart
mysql -u root -p
希望这可以帮助
