最近准备学习php,所以就配了个apache2,突然发现每次启动apache都会提示 Apache2: Could not reliably determine the server’s fully qualified domain name, using 127.0.1.1 for ServerName这个错误,百度了一番,分享下解决方法:

在

sudo gedit /etc/apache2/httpd.conf

里面加一行ServerName localhost就OK了;
有可能你没有这个文件或者这个文件是空的,添加就行了.
然后我重启apache,发现还是提升这个错误,又百度了一番,发现是apache的默认配置文件apache2.conf中没有引用这个httpd.conf配置文件,解决办法是在include httpd.conf这个文件:

sudo gedit /etc/apache2/apache2.conf

找到

# Include module configuration:
Include /etc/apache2/mods-enabled/*.load
Include /etc/apache2/mods-enabled/*.conf
……
# Include ports listing
Include ports.conf
……
# Include generic snippets of statements
Include conf.d/
……
# Include the virtual host configurations:
Include sites-enabled/

这些语句随便哪里插入:

# Include all the user configurations:
Include httpd.conf

就可以了.
还有一点,更改默认的web文档根目录:对于Ubuntu而言，默认的是/var/www。怎么知道的呢？apache2.conf里并没有DocumentRoot项，httpd.conf又是空的，因此肯定在其他的文件中。经过搜索，发现在/etc/apache2/sites-enabled/000-default中，里面有这样的内容：

NameVirtualHost *
<VirtualHost *>
ServerAdmin webmaster@localhost
DocumentRoot /var/www/

这个就是了.更改成你想要的就可以了,当然别忘了设置权限哦!
