我已在我的计算机上安装了Lampp，该计算机在OpenSuse 13.1上运行。问题是我无法从主机名' localhost '访问mysql，但可以通过主机名' localhost：3306 '或' 127.0.0.1访问它”。那太奇怪了！这真的搞砸了我的项目。伙计们有没有办法从主机名localhost访问mysql？ 提前谢谢！
这是我的主机文件：
127.0.0.1 localhost
# special IPv6 addresses
::1 localhost ipv6-localhost ipv6-loopback
fe00::0 ipv6-localnet
ff00::0 ipv6-mcastprefix
ff02::1 ipv6-allnodes
ff02::2 ipv6-allrouters
ff02::3 ipv6-allhosts
127.0.0.1 HOME-PC.home # added by Apache Friends XAMPP
127.0.0.1 HOME-PC # added by Apache Friends XAMPP
和我的/opt/lampp/etc/my.cnf文件：
# The following options will be passed to all MySQL clients
[client]
#password = your_password
port = 3306
socket = /opt/lampp/var/mysql/mysql.sock
# Here follows entries for some specific programs
# The MySQL server
[mysqld]
user = mysql
port=3306
socket = /opt/lampp/var/mysql/mysql.sock
