Configuring static IP addresses in Linux

Just installed CentOS, the default configuration is dynamic IP, if the virtual machine restarted (although not often), the IP address switched, and then use the Remote tool connection to re-change the address, laborious.

Today, a static address is set and recorded.

Environment: VMware 10.0.0 + CentOS 6

First, set up VMware's network settings

• Edit > virtual Network Editor
  • VMnet8 > Nat Mode (IP address of shared host with virtual machine)
    • Select "Nat Settings" and remember "Gateway IP" (set to use later)
  • Uncheck the "Use local DHCP service to assign IP addresses to virtual machines" check box
• Right-click installed systems > Settings > Network adapters > select NAT Mode
  
  • By the way, click "Advanced", note the MAC address (set to use later)

Modifying a Linux configuration file

As the following configuration file needs to be modified, modify the information after the file for the example below, it is recommended to pre-modify the backup:

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

This case hypothesis data:

• Gateway ip:192.168.116.2
• The static ip:192.168.116.130 to be set
• MAC Address: XX:XX:XX:XX:XX:XX

networking=yeshostname=localhost.localdomaingateway=192.168.116.2

/etc/sysconfig/network

Device= "eth0"# Bootproto= "DHCP"bootprote= "Static"ipaddr=192.168.116.130 NETMASK =255.255.255.0HWADDR= "XX:XX:XX:XX:XX:XX"ipv6init= "No"nm_controlled= "Yes"  Onboot= "Yes"TYPE= "Ethernet"UUID= "948bedc9-f08f-49cd-8c06-4a7a9fcd2e4e"DNS1= 192.168.116.2
