我试图进行复制并将我的服务器设置为从属服务器。我首先使用更改权限
sudo chmod 777 /etc/mysql/my.cnf
然后
sudo chown user:user -R /etc/mysql
然后我尝试安装记事本，它崩溃了。重新启动服务器并安装 Jedit。最后我编辑了添加的 my.cnf 文件
server-id=1359126008
在下面[mysqld]
在重新启动 mysql 然后重新启动服务器后，我收到了这个错误
Warning: mysql_connect(): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
现在我无法再连接了。该mysqld.sock文件也不存在于该文件夹中。
更新
user@ubuntu:~$ sudo service mysql start
start: Job failed to start
user@ubuntu:~$ sudo service mysql stop
stop: Unknown instance:
user@ubuntu:~$ sudo service mysql status
mysql stop/waiting
更新 2
来自 my.cnf 的位置：log_error = /var/log/mysql/error.log
日志中的所有现有行：

我无法让它工作。重新安装了mysql，现在它可以工作了。如果您担心数据库，mysql 给了我删除它们或保留它们的选项。我保留了它们，安装了 mysql，使用了与以前相同的 root 通行证，现在一切正常！！多谢你们！
