Ubuntu无法进入mysql，报ERROR 2002 (HY000): Can't connect to local MySQL server through socket …错误

在Ubuntu下进入mysql 时，报ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' 错误。检查发现是因为mysql没有启动。

输入 sudo service mysql start 后，又出现Couldn't find MySQL server (/usr/bin/mysqld_safe)错误，经过多方查阅，最后将mysql文件下的my.conf文件删掉，问题得到解决。

rm /etc/mysql/my.cnf
