Linux Configure static IP, turn off firewall

Installing centos6.5 under VMware accesses the extranet via bridging, so you need to configure the IP.

I. IP configuration

1.1. Configure Dynamic IP

Vi/etc/sysconfig/network-scripts/ifcfg-eth0

Device=eth0
hwaddr=00:0c:29:e1:e4:8e
Type=ethernet
uuid=f271bf73-7d8f-448f-8e8b-71c39eb13509
Onboot=yes (important is enabled)
Nm_controlled=yes
BOOTPROTO=DHCP (Important configuration)

2.2. Configure Dynamic IP

Device=eth0
Hwaddr=00:0c:29:b1:f1:24
Type=ethernet
uuid=8887bd2f-999f-4a85-912e-2a98b7ac4465
Nm_controlled=yes
Onboot=yes
Bootproto=static (Static)
broadcast=192.168.2.255
ipaddr=192.168.2.48 (the IP address must be the same network number as the host)
netmask=255.255.248.0 (subnet mask, must be the same as host)
gateway=192.168.1.1 (network management must be the same as host)
Arpcheck=no (important)

IP Settings for the host

　　

2.3. Restart the network

Service Network restart

When the ping extranet discovers that DNS is not found, you need to configure DNS

2.4. DNS Configuration

VI /etc/resolv.conf

Add the following:

NameServer 8.8.8.8
NameServer 8.8.4.4

2.5. Restart

Service Network restart

Three. Turn off the firewall

3.1. Service iptables stop (off)

3.2. Chkconfig iptables off (permanently off)

3.3. Status View

Service Iptables Status
