CentOS添加永久静态路由http://blog.chinaunix.net/u1/42991/showart_2090676.html在使用双网卡，同时使用2个网关的时候就需要加一条静态路由了。当然还有很多时候会需要加路由。一：使用route命令添加使用route命令添加的路由，机器重启或者网卡重启后路由就失效了，方法：//添加到主机的路由#routeadd–host192.168.1.11deveth0#routeadd–host192.168.1.12gw192.168.1.1//添加到网络的路由#routeadd–net192.168.1.11netmask255.255.255.0eth0#routeadd–net192.168.1.11netmask255.255.255.0gw192.168.1.1#routeadd–net192.168.1.0/24eth1//添加默认网关#routeadddefaultgw192.168.2.1//删除路由#routedel–host192.168.1.11deveth0二：在linux下设置永久路由的方法：1.在/etc/rc.local里添加方法：routeadd-net192.168.3.0/24deveth0routeadd-net192.168.2.0/24gw192.168.2.2542.在/etc/sysconfig/network里添加到末尾方法：GATEWAY=gw-ip或者GATEWAY=gw-dev3./etc/sysconfig/static-routes:anynet192.168.3.0/24gw192.168.3.254anynet10.250.228.128netmask255.255.255.192gw10.250.228.129如果在rc.local中添加路由会造成NFS无法自动挂载问题，所以使用static-routes的方法是最好的。无论重启系统和servicenetworkrestart都会生效以下是蚊子解决NFS问题的描述：按照linux启动的顺序，rc.local里面的内容是在linux所有服务都启动完毕，最后才被执行的，也就是说，这里面的内容是在netfs之后才被执行的，那也就是说在netfs启动的时候，服务器上的静态路由是没有被添加的，所以netfs挂载不能成功。static-routes文件又是什么呢，这个是network脚本执行时调用的一个文件，这个文件的放置在/etc/sysconfig目录下，在network脚本中的位置是：#Addnoninterface-specificstatic-routes.if[-f/etc/sysconfig/static-routes];thengrep"^any"/etc/sysconfig/static-routes|whilereadignoreargs;do/sbin/routeadd-$argsdonefi从这段脚本可以看到，这个就是添加静态路由的方法，static-routes的写法是anynet192.168.0.0/16gw网关ip这样的话，在启动network脚本的时候路由就自动添加上了，又因为network是在netfs前面启动的，自然在挂载nfs的时候就正常了。这样看来，如果需要添加静态路由，使用static-routes文件要比使用rc.local好，而且当改变了网络配置，需要重启network脚本的时候，相应的静态路由是可以自动添加上的，但这时如果使用rc.local的话，在重启network服务的时候，原本添加好的静态路由就消失了。http://www.udomaindelivery.com/et2009daily/actionpage/Apache/2.2.3(CentOS)Serveratwww.udomaindelivery.comPort80
