apache安装完之后，右下角的图标却是红色的。放鼠标上去的提示是：No services installed ，很显然，是由于服务没有安装。
解决办法是：
我的安装路径是：C:\Program Files\Apache Software Foundation\Apache2.2
1、打开cmd定位到：C:\Program Files\Apache Software Foundation\Apache2.2\bin
2、输入httpd.exe -k install -n apache2
出现以下提示：
C:\Program Files\Apache Software Foundation\Apache2.2\bin>httpd.exe -k install -
n apache2
Installing the apache2 service
The apache2 service is successfully installed.
Testing httpd.conf....
Errors reported here must be corrected before the service can be started.
httpd.exe: Could not reliably determine the server's fully qualified domain name
, using 192.168.1.212 for ServerName
解决这个问题方法：把/conf/httpd.conf文件的#ServerName 前的#去掉，再执行上面的操作。
再输入net start apache2
之后我们看见了成功的信息
httpd: Could not reliably determine the server's fully qualified domain name
在windows下安装好apache服务器后，重新启动后，回出现上面的错误，只要把/conf/httpd.conf文件的#ServerName 前的#去掉就好了。
