Configure the IP address of ubuntu server

During this time, the hadoop cluster environment was deployed to linux, which involved some linux configurations and was recorded for later use. Linux IP addresses are divided into two types: DHCP Dynamic Allocation and Static address allocation. In the past, dynamic allocation was used. However, IP addresses were always changed due to system reasons, and they were configured as Static IP addresses. In ubuntu server 11.10, the configuration is as follows: Use the vi editor to open the/etc/network/interfaces file Java code 1. # The primary network interface 2. auto eth0 3. iface eth0 inet dhcp # The primary network interface auto eth0 iface eth0 inet dhcp modify The Java code 1 in The following way. # The primary network interface 2. auto eth0 3. iface eth0 inet static 4. 5. # The IP address to be configured. 6. address 192.168.182.130 7. 8. # gateway address 9. gateway 192.168.182.2 10. 11. # subnet mask 12. netmask 255.255.255.0 13. 14. # broadcast address 15. # broadcast 192.168.182.255 16. # network 192.168.182.0 # The primary network interface auto eth0 iface eth0 inet static # IP address to be configured address 192.168.182.130 # gateway address gateway 192.168.182.2 # subnet mask netmask 255.255.255.0 # broadcast address # broadcast 192.168.182.255 # network 192.168.182.0 then execute the following command to make the configuration take effect Java code 1. root @ wenbo00: // #/etc/init. d/networking restart author zllz5230
