查看centos网关是否设置正确

[root@localhost ethan]# grep GATEWAY /etc/sysconfig/network-scripts/ifcfg*
/etc/sysconfig/network-scripts/ifcfg-eth0:GATEWAY=192.168.199.1

不正确就设置：

[root@localhost ethan]#vim /etc/resolv.conf    如下：

nameserver 192.168.15.1   --此处为VMWare中配置的网关
search localdomain

设置网关：

[root@localhost ethan]#vim /etc/sysconfig/network 如下：

NETWORKING=yes
HOSTNAME=localhost.localdomain
GATEWAY=192.168.15.1
 

[root@localhost ethan]# vim /etc/sysconfig/network-scripts/ifcfg-eth0  如下：

TYPE=Ethernet
BOOTPROTO=static
DEVICE=eth0
IPADDR=192.168.199.213
NETMASK=255.255.255.0
ONBOOT=yes
GATEWAY=192.168.199.1

4.最后重启网络服务

service network restart
