RHEL6 server network configuration

1. Modify the ip address method in linuxRHEL6 (1) [root @ www ~] # System-config-network graphical configuration for IP Address Configuration (2) [root @ www ~] # Vi/etc/sysconfig/network-scripts/ifcfg-eth0 manually modify the ip address of eth0 NIC (1) DEVICE = eth0 ---------------- Nic name (2) BOOTPRO

1. Modify the ip address method in linux RHEL6
(1) [root @ www ~] # System-config-network
Configure IP addresses using graphical Configuration
(2) [root @ www ~] # Vi/etc/sysconfig/network-scripts/ifcfg-eth0

Manually modify the ip address of the eth0 Nic
(1) DEVICE = eth0 ------------------ Nic name

(2) BOOTPROTO = none -------------- whether the network is obtained through DHCP or static IP. If it is DHCP, it is changed to dhcp. If it is static, it is changed to static.

(3) NM_CONTROLLED = no ----------- whether the network is affected by NetworkManager. In RHEL6, the NetworkManager function is added. We recommend that you disable it.

(4) ONBOOT = yes ---------------------- whether the network is started
(5) DNS1 = 172.16.2.1 ----------------------- DNS
(6) TYPE = Ethernet ------------------------ TYPE: Ethernet
(7) USERCTL = no -------------------------- none
(8) IPV6INIT = no ------------------------ whether IPV6 is enabled
(9) HWADDR = b8: 22: e3: 44: 36: 0e --------- hardware serial number, that is, the MAC address. If not, the system automatically adds

(10) IPADDR = 172.16.2.151 --------------- manually entered IP Address
(11) NETMASK = 255.255.255.0 --------------- Subnet Mask
(12) GATEWAY = 172.16.2.1 -------------------- GATEWAY
After modification, save and exit.

2. Configure whether the NIC is available and Host Name
[Root @ www ~] # Vim/etc/sysconfig/netwrok -- global configuration
NETWORKING = yes -------------------------- the global setting is used. If no is used, the network of the local machine is unavailable.
HOSTNAME = www.linuxidc.com ------------ host name. We recommend that you change it to x.x.com.

Then bind the IP address and Host Name
[Root @ www ~] # Vim/etc/hosts
Add IP address and Host Name
172.16.2.151 www.linuxidc.com

3. Activate NetworkManager
[Root @ www ~] # Service NetworkManager restart (or start)

Or
[Root @ www ~] #/Etc/init. d/NetworkManager restart (or start)

4. Activate the network
[Root @ www ~] # Service network restart (or start)
Or
[Root @ www ~] #/Etc/inie. d/networkrestart (or start)

5. Modify NDS configurations
[Root @ www ~] # Vi/etc/resolv. conf
Nameserver 8.8.8.8
