氣蒙我了，下午光給小孩除錯問題了

小孩來找我，說用xshell連伺服器上安裝資料庫出現下面的問題

[oracle@MemSell database]$ ./runInstaller

這個問題我只在本機執行的時候見過，xshell沒見過這個錯誤，查了1個小時，我決定自己查一遍所有的配置，結果一上來我發現小孩把/etc/hosts寫成了下面的樣子，氣死我了，改了就好用了，真不能相信別人。

 

[root@MemSell ~]# cat /etc/hosts
127.0.0.1 SrCent63x64-MemSell
*.*.*.* SrCent63x64-MemSell
*.*.*.* SrCent63x64-MemSell

 

[root@MemSell ~]# cat /etc/hosts
127.0.0.1       localhost.localdomain localhost
::1        localhost6.localdomain6 localhost6
*.*.*.*  MemSell
