full qualified hostname解决方法

#<--- full qualified hostname !!解决方法

cause：在sysctl.cfg中配置kernel参数和hosts配置名称有出入

solution:

1. 核对sysctl.cfg中kernel.hostname、kernel.domain和hosts中是否一致，最后再检查/etc/sysconfig/network中的hostname配置三者是否统一。

[root@ilearn ~]# vi /etc/sysctl.conf

 kernel.hostname   = ilearn.ilearning.com  #<--- full qualified hostname !!

 kernel.domainname = ilearn               #<--- correct domain name !!

去掉这两个参数配置

 

 查看hosts文件配置信息

[root@ilearn ~]# vi /etc/hosts

127.0.0.1       localhost.localdomain   localhost

192.168.1.159   ilearn.ilearning.com    ilearn

查看network配置信息

[root@ilearn ~]# vi /etc/sysconfig/network

NETWORKING=yes

NETWORKING IPV6=no

HOSTNAME=ilearn.ilearning.com

查看网卡mac地址信息

[root@ilearn ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0

BOOTPROTO=none

BROADCAST=192.168.1.255

HWADDR=00:0c:29:0c:6b:57        #网卡mac信息，在图形界面中Applications->System Settings-NetWork-Devices->Edit->HardWaredevice 点击probe --保存

IPADDR=192.168.1.159

NETMASK=255.255.255.0

NETWORK=192.168.1.0

ONBOOT=yes

TYPE=Ethernet

GATEWAY=192.168.1.1

USERCTL=no

IPV6INIT=no

PEERDNS=yes

最后重启

[root@ilearn ~]#  reboot
