[

2008/09/29 19:47 | by askwan ]

OS1:Linux
Network Interface: eth0
IP: 61.152.1.1

OS2: FreeBSD
Network Interface: fxp0
IP: 210.51.1.1

预配置：
OS1: 10.0.0.1 / 255.255.255.252
OS2: 10.0.0.2 / 255.255.255.252

OS1上配置
配置ipip隧道

Quotation

#ip tunnel add tun0 mode ipip remote 210.51.1.1 local 61.152.1.1 dev eth0
#ifconfig tun0 10.0.0.1 netmask 255.255.255.252 pointopoint 10.0.0.2
#ifconfig tun0 mtu 1500 up

OS2配置隧道

Quotation

#ifconfig gif0 create
#gifconfig gif0 inet 210.51.1.1 61.152.1.1
#ifconfig gif0 10.0.0.2 netmask 255.255.255.252 10.0.0.1
#ifconfig gif0 mtu 1500 up

OS1测试：
#ping -c 4 10.0.0.2

PING 10.0.0.2 (10.0.0.2) 56(84) bytes of data.
64 bytes from 10.0.0.2: icmp_seq=1 ttl=64 time=0.139 ms
64 bytes from 10.0.0.2: icmp_seq=2 ttl=64 time=0.138 ms
64 bytes from 10.0.0.2: icmp_seq=3 ttl=64 time=0.138 ms
64 bytes from 10.0.0.2: icmp_seq=4 ttl=64 time=0.136 ms

httpd: apr_sockaddr_info_get() failed 错误

[

今天一客户机器出现这种错误

Quotation

[root@server ]/usr/local/apache2/bin/apachectl start
httpd: apr_sockaddr_info_get() failed for server
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName

一般是由于系统hostname设置不当或者混乱造成的
解决方法：
确保系统hostname指令得出的值与 /etc/hosts 和 /etc/sysconfig/network所对应的值一致

这也提醒我们修改系统的主机名为了不必要的麻烦就要同时修改这两个文件才行
再次启动httpd 就不会有这个错误了
至于下面这一行设置apache配置文件将ServerName 设置为对应IP地址即可
