前言

记录一下vmware如何克隆一个虚拟机，并解决克隆的centos7虚拟机遇到的网络问题

克隆方法

右键点击要克隆的虚拟机->管理->克隆，然后下一步->下一步，克隆类型选择创建完整克隆->输入虚拟机名称，选择位置，点击完成，然后等待一直到完成

开启虚拟机

输入用户名、密码，和之前被克隆的用户名密码一样

修改克隆后的ip

因为之前我设置的固定ip(vmware centos7 设置固定ip)，所以克隆后的ip和我之前设置的固定ip一致，这样会冲突，需要修改

不修改的话ip会随机生成，并且每次都可能不一样，不重启虚拟机ip也会主动变化

vi /etc/sysconfig/network-scripts/ifcfg-eno16777736
IPADDR=192.168.44.129

重启网络

service network restart

然后发现重启失败

[root@master ~]# service network restart
Restarting network (via systemctl):  Job for network.service failed. See 'systemctl status network.service' and 'journalctl -xn' for details.
                                                           [FAILED]

查看网络状态也是失败的

root@master ~]# systemctl status network
network.service - LSB: Bring up/down networking
   Loaded: loaded (/etc/rc.d/init.d/network)

异常解决

修改mac地址

查看mac地址

[root@master ~]# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> 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 forever
2: eno16777736: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:0c:29:19:34:5c brd ff:ff:ff:ff:ff:ff
    inet 192.168.44.132/24 brd 192.168.44.255 scope global dynamic eno16777736
       valid_lft 1150sec preferred_lft 1150sec
    inet6 fe80::20c:29ff:fe19:345c/64 scope link 
       valid_lft forever preferred_lft forever

link/ether和brd之间的00:0c:29:19:34:5c就是我们要复制的新mac地址

修改

vi /etc/sysconfig/network-scripts/ifcfg-eno16777736
HWADDR="00:0c:29:19:34:5c"

然后重启网络

[root@master ~]# service network restart
Restarting network (via systemctl):                        [  OK  ]

重启虚拟机

重启网络，用ifconfig 查看ip地址并没有改变为我们修改的192.168.44.129，重启一下虚拟机，再查看一下就会发现生效了
