CentOS7下怎么配置虚拟路由器

这篇文章主要介绍"CentOS7下怎么配置虚拟路由器"，在日常操作中，相信很多人在CentOS7下怎么配置虚拟路由器问题上存在疑惑，小编查阅了各式资料，整理出简单好用的操作方法，希望对大家解答"CentOS7下怎么配置虚拟路由器"的疑惑有所帮助！接下来，请跟着小编一起来学习吧！

一、环境及需求说明

本地测试环境，由于win7+vmware这台机器网卡太新，无法被vmware exsi识别，无奈之下就直接装了个win7，然后再上面基于vmware workstation 12开启了一些临时测试的虚拟机。其次本地直连网段192.168.1.0 ip有限，而又希望直接从本机(如图win10) ssh连接到这些虚拟机，因此考虑使用linux的ip转发功能来实现。

上述图片中已经列出了各个节点的ip信息，红色的虚拟机充当软路由，配置好之后，实现win10 直接ssh到虚拟机。

二、虚拟路由服务器配置

###查看网卡信息[root@centos7-router ~]# ip addr1: lo:  mtu 65536 qdisc noqueue state unknown   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_lft forever preferred_lft forever  inet6 ::1/128 scope host    valid_lft forever preferred_lft forever2: eno16777728:  mtu 1500 qdisc pfifo_fast state up qlen 1000  link/ether 00:0c:29:9c:eb:2d brd ff:ff:ff:ff:ff:ff  inet 172.24.8.254/24 brd 172.24.8.255 scope global eno16777728   valid_lft forever preferred_lft forever  inet6 fe80::20c:29ff:fe9c:eb2d/64 scope link    valid_lft forever preferred_lft forever3: eno33554960:  mtu 1500 qdisc pfifo_fast state up qlen 1000  link/ether 00:0c:29:9c:eb:37 brd ff:ff:ff:ff:ff:ff  inet 192.168.1.175/24 brd 192.168.1.255 scope global dynamic eno33554960   valid_lft 82384sec preferred_lft 82384sec  inet6 fe80::20c:29ff:fe9c:eb37/64 scope link    valid_lft forever preferred_lft forever###查看路由表[root@centos7-router ~]# route -nkernel ip routing table ###缺省情况下，每块网卡都有一个基于本网段的路由记录destination  gateway    genmask    flags metric ref  use iface0.0.0.0    192.168.1.1  0.0.0.0    ug  100  0    0 eno33554960172.24.8.0   0.0.0.0    255.255.255.0 u  100  0    0 eno16777728192.168.1.0  0.0.0.0    255.255.255.0 u  100  0    0 eno33554960###使用ip命令方式查看路由[root@centos7-router ~]# ip route listdefault via 192.168.1.1 dev eno33554960 proto static metric 100 172.24.8.0/24 dev eno16777728 proto kernel scope link src 172.24.8.254 metric 100 192.168.1.0/24 dev eno33554960 proto kernel scope link src 192.168.1.175 metric 100 ###开启ip forward[root@centos7-router ~]# cp /usr/lib/sysctl.d/50-default.conf /usr/lib/sysctl.d/50-default.conf.bk[root@centos7-router ~]# echo "net.ipv4.ip_forward = 1" >>/usr/lib/sysctl.d/50-default.conf[root@centos7-router ~]# grep ip_forward /usr/lib/sysctl.d/50-default.confnet.ipv4.ip_forward = 1[root@centos7-router ~]# sysctl -p ###如不生效重启一下os

三、centos7-a主机下添加路由

###查看当前主机ip 信息[root@centos7-a ~]# ip addr list1: lo:  mtu 65536 qdisc noqueue state unknown   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_lft forever preferred_lft forever  inet6 ::1/128 scope host    valid_lft forever preferred_lft forever2: eno16777728:  mtu 1500 qdisc pfifo_fast state up qlen 1000  link/ether 00:0c:29:57:26:9d brd ff:ff:ff:ff:ff:ff  inet 172.24.8.131/24 brd 172.24.8.255 scope global dynamic eno16777728   valid_lft 1088sec preferred_lft 1088sec  inet6 fe80::20c:29ff:fe57:269d/64 scope link    valid_lft forever preferred_lft forever###查看当前主机路由信息   [root@centos7-a ~]# ip route list172.24.8.0/24 dev eno16777728 proto kernel scope link src 172.24.8.131 metric 100 [root@centos7-a ~]# # author : leshami[root@centos7-a ~]# # blog : http://blog.csdn.net/leshami[root@centos7-a ~]# ip route add default via 172.24.8.254[root@centos7-a ~]# ip route listdefault via 172.24.8.254 dev eno16777728 172.24.8.0/24 dev eno16777728 proto kernel scope link src 172.24.8.131 metric 100 ###测试到虚拟路由器网关ip连通性[root@centos7-a ~]# ping 172.24.8.254 -c 2       ping 172.24.8.254 (172.24.8.254) 56(84) bytes of data.64 bytes from 172.24.8.254: icmp_seq=1 ttl=64 time=0.268 ms64 bytes from 172.24.8.254: icmp_seq=2 ttl=64 time=0.302 ms--- 172.24.8.254 ping statistics ---2 packets transmitted, 2 received, 0% packet loss, time 1000msrtt min/avg/max/mdev = 0.268/0.285/0.302/0.017 ms###测试到虚拟路由器ip连通性[root@centos7-a ~]# ping 192.168.1.175 -c 2ping 192.168.1.175 (192.168.1.175) 56(84) bytes of data.64 bytes from 192.168.1.175: icmp_seq=1 ttl=64 time=0.475 ms64 bytes from 192.168.1.175: icmp_seq=2 ttl=64 time=0.443 ms--- 192.168.1.175 ping statistics ---2 packets transmitted, 2 received, 0% packet loss, time 1000msrtt min/avg/max/mdev = 0.443/0.459/0.475/0.016 ms

四、windows 10下配置路由
