添加路由遇到的问题：SIOCADDRT: File exists

原因：路由已经存在了。

 

解决方法：

从网上搜到的：

1. Open ifcfg file vi /etc/sysconfig/network-scripts/ifcfg-eth0:7 
2. NETWORK=217.174.242.0 Make sure this address is unique to each ifcfg file; if you use the same address in another ifcfg file you will receive the aforementioned error.
3. Edit if required by pressing i to begin insert mode, make the changes, then pressing Esc to return to view mode.
3. Save the document by using a SHIFT ZZ combination.
4. Restart the network: service network restart
