论坛里面说要改config.inc.php
原因： 如果未指定主机名或指定了特殊的主机名localhost,将指向Linux套接字，而源码编译安装的mysql套接字默认是/tmp/mysql.sock，而本机并没有配置这样的套接字文件，所以会出现上述错解决方法根据自己的安装路径，找到config.inc.php文件，编辑打开找到如下行$cfg['Servers'][$i]['host'] = 'localhost';修改为如下$cfg['Servers'][$i]['host'] = '127.0.0.1';然后重新登录即可
请问config.inc.php在哪里？找了大半天找不到。,mysql无法正常运行，请问config.inc.php在哪里？找了大半天找不到。

答：您好，根据mysql报错日志分析，是由于内存不足引起的，请您先尝试重启下服务器再试试启动mysql，如经常出现这个问题，请升级服务器内存。
您当前是独立IP主机，如需我司进入服务器处理，请重新提交正确类型独立IP主机工单，类型选择：??【主机租用 vps、云主机】 -> 数据库设置 -> 数据库服务启动失败/使用出错 ?? ，提交此工单我司会按照服务标准为您处理（处理标准：https://www.west.cn/services/server/vip_vps.asp ），部分问题可能会涉及费用产生，谢谢。
问：请问config.inc.php在哪里？
问：我的内存还剩挺多的啊
问：内存还有1/3
答：您好，建议可在服务器内输入reboot重启试试，phpmy的配置一般不需要修改，出现这个报错的原因是数据库没有启动引起的。
如无法解决，可以提交下【??主机租用 vps、云主机】 -> 数据库设置 -> 数据库服务启动失败/使用出错类型工单，我司尝试处理下，谢谢。??
