1 Virtual machine selects NAT mode
2 Get the gateway address of vmnet8 in mac machine
Open the mac terminal and enter the following command
cat /Library/Preferences/VMware Fusion/vmnet8/nat.conf
- 1
Find the line # NAT gateway address, the ip below is the gateway address
3 Modify the ifcfg-xxx file in Centos7
Enter the directory: / etc / sysconfig / network-scripts
Find ifcfg-ens33 file
Edit this file to add or modify BOOTPROTO, IPADDR, NETMASK, DNS1, DNS2, GATEWAY, ONBOOT configuration. IPADDR is the static ip value that needs to be set; NETMASK is NETMASK for mac; DNS1 and DNS2 are also the dns configuration in mac; GATEWAY is the ip value under gateway addr found in step
mac-> System Preferences-> Network click on the advanced as shown below
The value of ifcfg-ens33 after configuration is as shown below, remember to turn off dns automatic acquisition
4 reboot centos can successfully connect to the network
Follow up
I recently installed a solid state drive on macpro, copied all the files to the solid state drive, and used this solid state drive as the startup disk. When starting the virtual machine here, only one of the three virtual machines can be started. Run ifconfig to view Cannot reach the set IP address; executing systemctl status network.service reports an error: Failed to start LSB: Bring up / down networking. Found a lot of solutions on the Internet keyword "centos7 can not start the network card" Most of them are to modify the /etc/.../ifcfg-ens33 file name and modify the DEVICE value inside, or add the MAC address, etc. Useless. After searching for a long time, I finally know the cause of the problem. The reasons are as follows:
This problem is related to the management software NetworkManager that comes with the system. You can solve it by shutting down the software and restarting the network card. The specific commands are as follows
systemctl stop NetworkManager
systemctl disable NetworkManager
systemctl start network.service
The above method can ensure that centos7 can access the external network, but other machines except the host computer can not access it. The following is the way to configure the local network to be able to access, and to be able to access the external network.
1 Turn off the virtual machine
2 Click on the virtual machine settings-> click on add device
3 Click on the WIFI in the bridge mode network connection, click on the "Generate" button on the right side of the advanced options
4. Turn off the original network adapter
5 Start the virtual machine:-) This When you can access the external network normally, you can also be accessed by the internal network. Remember to set the virtual machine ip to the same LAN segment ip
Solve the problem that CentOS7 virtual machine can't go online and set CentOS7 virtual machine to use static IP to go online

1 虚拟机选择NAT模式
2 获取mac机器中vmnet8的gateway地址
打开mac终端，输入如下命令
cat /Library/Preferences/VMware Fusion/vmnet8/nat.conf
- 1
找到 # NAT gateway address这一行，下面的ip就是gateway地址
3 修改Centos7中ifcfg-xxx文件
进入目录：/etc/sysconfig/network-scripts
找到ifcfg-ens33文件
编辑此文件，增加或修改BOOTPROTO,IPADDR,NETMASK,DNS1,DNS2,GATEWAY,ONBOOT配置。其中IPADDR为需要设定的静态ip值；NETMASK为mac的NETMASK；DNS1,DNS2也是mac中的dns配置；GATEWAY就是第2步中找到的gateway addr下的ip值
mac ->系统偏好设置->网络 点击高级后 如下图
ifcfg-ens33配置后的值如下图，记住一定要关闭dns自动获取
4 reboot centos 就能成功连接网络了
