CentOS7、CentOS6添加永久静态路由
本人在实际工作中经常需要添加永久静态路由，故整理此文。我这里只列举最快捷有效的添加方法，其他方法大家可自行查找，本文不再赘述。 假设我这台机器有三块儿网卡，ip192.168.102.30配置在网卡eth0上，掩码是255.255.255.0，网关是192.168.102.1，需要与192.168.100.0段内所有服务器通信，以下是路由设置方法。 1. CentOS7添加永久静态路由方法输入ip route show | column -t查看当前路由表： [root@test ~]# ip route show | column -t 192.168.102.0/24 dev eth0 proto kernel scope link src 192.168.102.107 metric 100 [root@test ~]#输入命令ip addr查看所需经过的网卡的名称： [root@test ~]# ip addr 1: lo: mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_Ift forever preferred_Ift forever inet6 ::1/128 scop host valid_Ift forever prefeered_Ift forever 2: eth0: mtu 1500 qdisc mq state UP group default qlen 1000 link/ether 00:13:dd:a2:08:00 brd ff:ff:ff:ff:ff:ff inet 192.168.102.30/24 brd 192.168.102.255 scope global noprefixroute eth0 valid_Ift forever preferred_Ift forever inet6 ed20::21c:5dff:fe64:3000/64 scop link valid_Ift forever prefeered_Ift forever 3: eth1: mtu 1500 qdisc mq state DOWN group default qlen 1000 link/ether 00:13:dd:a2:08:01 brd ff:ff:ff:ff:ff:ff 4: eth2: mtu 1500 qdisc mq state DOWN group default qlen 1000 link/ether 00:13:dd:a2:08:02 brd ff:ff:ff:ff:ff:ff [root@test ~]#从以上回显中可以得知所需经过的网卡名为eth0，然后我们用vi编辑器在以下路径创建文件route-eth0并编辑： [root@test ~]# vi /etc/sysconfig/network-scripts/route-eth0在route-eth0文件中添加以下行：192.168.100.0/24 via 192.168.102.1 dev eth0 其中，192.168.100.0/24是目标网段及掩码，192.168.102.10是网关，dev eth0是途径设备。 192.168.100.0/24 via 192.168.102.1 dev eth0 ~ ~ ~ ~ ~ ~ ~ "/etc/sysconfig/network-scripts/route-eth0" 3L, 89C添加完成后按Esc退出编辑，输入“:wq”，敲击回车保存并退出： 192.168.100.0/24 via 192.168.102.1 dev eth0 ~ ~ ~ ~ ~ ~ ~ :wq随后输入service network restart重启网络服务： [root@test ~]# service network restart Restarting network (via systemctl): [ ok ] [root@test ~]#ping一下目标网段的机器，看看通不通，按Ctrl+C中断： [root@test ~]# ping 192.168.100.226 PING 192.168.100.226 (192.168.100.226) 56(84) bytes of data. 64 bytes from 192.168.100.226: icmp_seq=1 ttl=255 time=1.33 ms 64 bytes from 192.168.100.226: icmp_seq=2 ttl=255 time=1.34 ms 64 bytes from 192.168.100.226: icmp_seq=3 ttl=255 time=1.56 ms ^C --- 192.168.100.226 ping statistics --- 3packets transmitted, 3 received, 0% packet loss, time 2002ms rtt min/avg/max/mdev = 1.339/1.417/1.565/0.104 ms [root@test ~]#输入ip route show | column -t查看路由表中是否有刚才添加的路由： [root@test ~]# ip route show | column -t 192.168.100.0/24 via 192.168.102.1 dev eth0 proto static metric 100 192.168.102.0/24 dev eth0 proto kernel scope link src 192.168.102.30 metric 100 [root@test ~]# 至此，CentOS7操作系统下永久静态路由设置完成。 2. CentOS6添加永久静态路由方法CentOS6要比CentOS7简单粗暴的多。 输入route -n查看当前路由表： [root@test2 ~]# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 192.168.102.1 255.255.255.0 UG 0 0 0 eth0 [root@test2 ~]#输入命令ifconfig查看所需经过的网卡的名称： [root@test2 ~]# ifconfig eth0 Link encap:Ethernet HWaddr 00:13:DD:A2:08:00 inet addr:192.168.102.30 Bcast:192.168.102.255 Mask:255.255.255.0 inet6 addr: ed20::21c:5dff:fe64::3000/64 Scope:Global inet6 addr: fe80::215:5d66::1100/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:32609036 errors:0 dropped:0 overruns:0 carrier:0 TX packets:83149 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:3808450527 (3.5 GiB) TX bytes:5266402 (5.0 MiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:346915 errors:0 dropped:0 overruns:0 frame:0 TX packets:346915 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:24878697 (23.7 MiB) TX bytes:24878697 (23.7 MiB) [root@test2 ~]#从以上回显中可以得知所需经过的网卡名为eth0，然后我们用vi编辑器在以下路径创建文件static-routes并编辑： [root@test2 ~]# vi /etc/sysconfig/static-routes在static-routes文件中添加以下行：any net 192.168.100.0 netmask 255.255.255.0 gw 192.168.102.1 其中，192.168.100.0是目标网段，netmask是子网掩码，192.168.102.1是途径网关。 any net 192.168.100.0 netmask 255.255.255.0 gw 192.168.102.1 ~ ~ ~ ~ ~ ~ ~ "/etc/sysconfig/static-routes" 3L, 189C添加完成后按Esc退出编辑，输入“:wq”，敲击回车保存并退出： 192.168.100.0/24 via 192.168.102.1 dev eth0 ~ ~ ~ ~ ~ ~ ~ :wq随后输入service network restart重启网络服务： [root@test2 ~]# service network restart Shutting down interface eth0: [ ok ] Shutting down loopback interface: [ ok ] Bringing up loopback interface: [ ok ] Shutting down interface eth0: Determining if ip address 192.168.102.30 is already in use for device eth0... [ ok ] [root@test2 ~]#ping一下目标网段的机器，看看通不通，按Ctrl+C中断： [root@test2 ~]# ping 192.168.100.226 PING 192.168.100.226 (192.168.100.226) 56(84) bytes of data. 64 bytes from 192.168.100.226: icmp_seq=1 ttl=255 time=1.81 ms 64 bytes from 192.168.100.226: icmp_seq=2 ttl=255 time=1.24 ms 64 bytes from 192.168.100.226: icmp_seq=3 ttl=255 time=1.89 ms 64 bytes from 192.168.100.226: icmp_seq=4 ttl=255 time=1.21 ms ^C --- 192.168.100.226 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3272ms rtt min/avg/max/mdev = 1.213/1.542/1.897/0.318 ms [root@test2 ~]#输入route -n查看路由表，看看刚才添加的路由是否存在： [root@test2 ~]# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.100.0 192.168.102.1 255.255.255.0 UG 0 0 0 eth0 0.0.0.0 192.168.102.1 255.255.255.0 UG 0 0 0 eth0 [root@test2 ~]# 至此，CentOS6操作系统下永久静态路由设置完成。本文到此结束。 |
