Set a fixed IP address for CentOS in VMware

Set a fixed IP address for CentOS in VMware

Because the replica set is not used for MongoDB fragments, and the current network is under a lot of pressure recently, so I want to study it. So I will build an environment in my own computer's virtual machine, however, it was found that VMware had previously set up DHCP, so the IP address in the virtual machine had changed every time after resume, which made it very difficult to re-build the mongodb environment that had already been set up, to set a static fixed IP address, follow these steps:

First, disable VMware DHCP:

Edit-> Virtual Network Editor

Select VMnet8 and remove the Use local DHCP service to distribute IP address to VMs option. Click NAT Settings to view the GATEWAY address:

Click OK.

Set CentOS fixed IP Address:

Three configuration files are involved:

/etc/sysconfig/network/etc/sysconfig/network-scripts/ifcfg-eth0/etc/resolv.conf

First, modify/etc/sysconfig/network as follows:

NETWORKING=yesHOSTNAME=localhost.localdomainGATEWAY=192.168.129.2

Specify the gateway address.

Then modify the/etc/sysconfig/network-scripts/ifcfg-eth0:

DEVICE="eth0"#BOOTPROTO="dhcp"BOOTPROTO="static"IPADDR=192.168.129.129NETMASK=255.255.255.0HWADDR="00:0C:29:56:8F:AD"IPV6INIT="no"NM_CONTROLLED="yes"ONBOOT="yes"TYPE="Ethernet"UUID="ba48a4c0-f33d-4e05-98bd-248b01691c20"DNS1=192.168.129.2

Note: DNS1 must be set. Otherwise, domain name resolution cannot be performed.

Finally, configure/etc/resolv. conf:

nameserver 192.168.129.2

In fact, this step can be omitted. After the DNS Server address is set above, the system will automatically modify this configuration file.

After a few steps, the IP address of the VM is 192.168.129.129.
