小孩来找我，说用xshell连服务器上安装数据库出现下面的问题
[oracle@MemSell database]$ ./runInstaller

这个问题我只在本机执行的时候见过，xshell没见过这个错误，查了1个小时，我决定自己查一遍所有的配置，结果一上来我发现小孩把/etc/hosts写成了下面的样子，气死我了，改了就好用了，真不能相信别人。
[root@MemSell ~]# cat /etc/hosts
127.0.0.1 SrCent63x64-MemSell
*.*.*.* SrCent63x64-MemSell
*.*.*.* SrCent63x64-MemSell

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