Question

我最近在我的mysql数据库上出现了一个错误并且没有更好的判断力（我根本不是服务器人）我试图通过谷歌搜索和更改服务器来解决它......

首先，mysql显示此错误＆＃34;无法创建/写入文件（错误代码：30）＆＃34;

我想我遵循了这些答案，最终导致了更多问题： MySQL: Can't create/write to file '/tmp/#sql_3c6_0.MYI' (Errcode: 2) - What does it even mean? http://nixcraft.com/showthread.php/14260-ERROR-1-(HY000)-Can-t-create-write-to-file-tmp-sql_9f3_0-MYI-(Errcode-13)

只回头看，我发现这些谷歌搜索的答案有不同的错误代码，而不是＆＃34; 30＆＃34;

以下是我所做的操作的日志，导致服务器在最后失败甚至更多（mysqld现在甚至没有重启）

[root@xxx ~]# /usr/sbin/lsof /tmp
[root@xxx ~]# /bin/umount -l /tmp
umount: /tmp: not mounted
[root@xxx ~]# /bin/umount -l /var/tmp
umount: /var/tmp: not mounted
[root@xxx ~]#  cat /etc/my.cnf | grep tmpdir

从上面列出的链接中，您会看到我尝试过诸如

之类的内容

"check mysql config : my.cnf
cat /etc/my.cnf | grep tmpdir
I can't see anything in my my.cnf
add tmpdir=/tmp to my.cnf under [mysqld]
restart web/app and mysql server
/etc/init.d/mysqld restart"
" chown root:root /tmp
  chmod 1777 /tmp
  /etc/init.d/mysqld restart"

但是，是的，我还没有触及它，因为我认为我只会把它弄得更糟。

运行的服务器是CentOS 6.5 64位LAMP

让我知道是否有人可以提供一些见解或我是否应该提供更多信息。谢谢！非常感谢。
