配置网络

设置跳板机（ecos01）的网络

设置固定ip地址

外网设置

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

修改为

DEVICE=eth0
BOOTPROTO=static
ONBOOT=yes
NETWORKING=yes
IPADDR=192.168.51.119
NETMASK=255.255.255.0
GATEWAY=192.168.51.1

内网设置

vim /etc/sysconfig/network-scripts/ifcfg-eth1

修改为

DEVICE=eth1
BOOTPROTO=static
ONBOOT=yes
IPADDR=10.0.0.1
NETMASK=255.255.255.0

设置DNS

vim /etc/resove.conf

修改nameserver

nameserver 192.168.0.230
nameserver 8.8.8.8

重启网络设置

service network restart

检查ip设置

ifconfig

成功会显示如下内容

在这里需要注意下ecos01这台机器的默认网关为192.168.51.1

设置Web服务器（ecos02/ecos03）的网络

服务器网络配置是相同的, 这里以10.0.0.2机器为例

设置固定ip地址

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

修改为

DEVICE=eth0
BOOTPROTO=static
ONBOOT=yes
NETWORKING=yes
IPADDR=10.0.0.2
NETMASK=255.255.255.0
GATEWAY=10.0.0.1

设置DNS

vim /etc/resove.conf

修改nameserver

nameserver 192.168.0.230
nameserver 8.8.8.8

重启网络设置

service network restart

检查ip设置

ifconfig

成功会显示如下内容
