报这个错connect to server at 'localhost' failed error: 'Can't connect to local MySQL server through socket '/tmp/mysql.sock' (11)' Check that mysqld is running and that the socket: '/tmp/mysql.sock' exists!帮我看下这到底是怎么回事，明明这个/tmp/mysql.sock是OK的，而且我是早上看的，根本网站没什么流量，我都怀疑是被攻击了... 迷茫...
贴出mysql日志和apache日志，linux发行版本。

手动映射一个mysql.sock文件到你的tmp目录下。1. stop mysql 2. run the commands# cd /tmp # ln -s /var/lib/mysql/mysql.sock mysql.sock //根据你的版本找到你的原始文件地址映射。 3. start mysql
我用过appserv的套件，安装好以后在MYSQL 的安装目录下有个my-huge.ini my-huge.ini my-innodb-heavy-4G.ini这几个配置文件。你可以参考一下

这个问题 ，我以前也碰到过。我上次的解决办法跟权限有关，正巧前两周硬盘坏了。。上次怎么解决就在硬盘上记录的。。
我linux一般用的版本是RH4和ubuntu 8.03。想赚点你的分都不行了，太巧和了，和我一样的错误。

3. start mysql
这个很重要的。。
ubuntu/centerOS/RH/Solaris/每个发行版本的情况都不一样的哦。
