平时工作经常需要配置路由，接下来总结一下linux服务器配置路由的方法。
1、首先看一下本机的网路环境网络信息及路由信息：ip addr;route -n。
2、接着使用route命令添加一条静态路由：route add -net 192.168.3.0 netmask 255.255.255.0 gw 192.168.2.1。
3、然后使用route命令添加一条路由，并指定eth1网卡：route add -net 192.168.4.0 netmask 255.255.255.0 gw 192.168.2.1 dev eth1。
4、接着使用route命令添加一条指向某一个主机的路由：route add -host 192.168.5.125 gw 192.168.2.1 。
5、最后使用ip命令添加一条静态路由，并指定从eth1网卡收发数据：ip route add 192.168.7.0/24 via 192.168.2.1 dev eth1，如下图所示添加静态路由就完成了。
linux下添加路由的方法：
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
# route add –host 192.168.168.110 dev eth0
# route add –host 192.168.168.119 gw 192.168.168.1
//添加到网络的路由
# route add –net IP netmask MASK eth0
# route add –net IP netmask MASK gw IP
# route add –net IP/24 eth1
//添加默认网关
# route add default gw IP
//删除路由
# route del –host 192.168.168.110 dev eth0
二：在linux下设置永久路由的方法：
1.在/etc/rc.local里添加
方法：
route add -net 192.168.3.0/24 dev eth0
route add -net 192.168.2.0/24 gw 192.168.3.254
2.在/etc/sysconfig/network里添加到末尾
方法：GATEWAY=gw-ip 或者 GATEWAY=gw-dev
3./etc/sysconfig/static-router :
any net x.x.x.x/24 gw y.y.y.y
用route命令，如 添加路由192.168.1.1 route add default gw 192.168.1.1
