【Linux网络配置实战】服务器Network静态路由配置
一、环境介绍
1.环境规划
hostname IP地址 网关 系统版本 server01 192.168.20.66 192.168.20.1 centos7.6 route01 192.168.20.254/24-172.16.10.254/24 — centos7.6 server02 172.16.10.66 172.16.10.1 centos7.6 2.实验目的
server02与server01可以互通
二、检查各节点IP地址
1.检查server01服务器上
[root@server01 ~]# ifconfig eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.20.66 netmask 255.255.255.0 broadcast 192.168.20.255 inet6 fe80::2a6e:d4ff:fe89:5da4 prefixlen 64 scopeid 0x20<link> ether 28:6e:d4:89:5d:a4 txqueuelen 1000 (Ethernet) RX packets 6020 bytes 682748 (666.7 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 112 bytes 17061 (16.6 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10<host> loop txqueuelen 1000 (Local Loopback) RX packets 4 bytes 344 (344.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 4 bytes 344 (344.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0- 1

3.检查route01上的网卡
[root@route01 ~]# ifconfig eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.20.254 netmask 255.255.255.0 broadcast 192.168.20.255 inet6 fe80::2a6e:d4ff:fe89:7954 prefixlen 64 scopeid 0x20<link> ether 28:6e:d4:89:79:54 txqueuelen 1000 (Ethernet) RX packets 5762 bytes 655197 (639.8 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 117 bytes 17132 (16.7 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 eth1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 172.16.10.254 netmask 255.255.255.0 broadcast 172.16.10.255 inet6 fe80::2a6e:d4ff:fe89:d1a0 prefixlen 64 scopeid 0x20<link> ether 28:6e:d4:89:d1:a0 txqueuelen 1000 (Ethernet) RX packets 3012 bytes 349027 (340.8 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 23 bytes 1499 (1.4 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10<host> loop txqueuelen 1000 (Local Loopback) RX packets 12 bytes 1040 (1.0 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 12 bytes 1040 (1.0 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0- 1

四、查看当前两节点互通情况
1.查看server01和server02连通状态
2.查看当前server01路由表
[root@server01 ~]# route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default gateway 0.0.0.0 UG 0 0 0 eth0 link-local 0.0.0.0 255.255.0.0 U 1002 0 0 eth0 192.168.20.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0- 1

2.新增网卡配置文件写入路由
[root@server02 network-scripts]# vim route-eth1 [root@server02 network-scripts]# cat route-eth1 192.168.20.0/24 via 172.16.10.254- 1

3.重启网络
[root@server02 network-scripts]# service network restart Restarting network (via systemctl): [ OK ]- 1

4.查看静态路由表
[root@server02 network-scripts]# route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default gateway 0.0.0.0 UG 100 0 0 eth0 172.16.10.0 0.0.0.0 255.255.255.0 U 100 0 0 eth0 192.168.20.0 172.16.10.254 255.255.255.0 UG 100 0 0 eth0- 1
