No Internet Connection from VMware with CentOS 7


New Look. New CentOS!
Yes, that’s what CentOS 7 says.
Anyway, lately, I installed CentOS 7 over VMware, and installation were quite smooth. Immediate after installation, I tried to browse some web, and it was failing.
While doing basic troubleshooting, I noticed there were no IP when I did ifconfig
[[email protected] ~]$ ifconfig
ens32: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
ether 00:0c:29:68:22:e2 txqueuelen 1000 (Ethernet)

Are you in the same situation as I was?
In this article, I will talk about how to fix if you don’t get the Internet on VMware with CentOS 7.
That leads me to think either network adaptor is not enabled or failed to obtain a DHCP IP address.
Solution
- Access terminal/console
- Become a root if you are not already
- Execute
dhclient –v
command - You will notice it will bound IP address as shown below
[[email protected] network-scripts]# dhclient -v

Boom, that’s all, you should have the Internet now. You will also notice IP when you do ifconfig
[[email protected] network-scripts]# ifconfig
ens32: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 172.16.179.136 netmask 255.255.255.0 broadcast 172.16.179.255

Add this in auto-startup
You might be interested in putting this in auto-startup, so you don’t have to do this every time you start the CentOS VM.
This is how you can put the script in auto-startup, so it starts automatically after VM is rebooted.
- Go to /etc/init.d
- Create a file with following, I have kept the name as “net-autostart“
#!/bin/bash
# Solution for "No Internet Connection from VMware"
#
### BEGIN INIT INFO
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
### END INIT INFO
dhclient -v
- Save the file
- Change the file permission as executable
chmod 755 net-autostart
- Add this script for auto-start using
chkconfig
command
chkconfig --add net-autostart
- Restart VM to test
I hope this helps.
