Apache22 启动异常

FreeBSD安装apache22后启动异常
httpd: Could not reliably determine the server's fully qualified domain name, using www.example.org for ServerName
Syntax OK
Starting apache22.
httpd: Could not reliably determine the server's fully qualified domain name, using www.example.org for ServerName

解决办法：
修改/etc/hosts:
127.0.0.1 localhsot
然后修改http.conf，加入
ServerName localhost:80

然后启动，直接提示failed to start，没有任何其他的提示，我们可以在log里面找信息，路径在/var/log，文件为httpd-error.log，查看内容，发现异常原因，于是在/etc/hosts里面加入一行
yourIPAddress   yourHostName
即可
