1. download apache httpd source
2. unzip it to /opt/httpd/httpd-2.2.9
3. cd /opt/httpd-2.2.9, 执行 "./configure --prefix="/opt/httpd-2.2.9"
4. make
5. make install
6. bin/apachectl start，然后打开首页 http://192.168.0.100/, it should show "it works"

注意文件中有三处主要的地方需要修改下的：
apachectl=/usr/local/apache/bin/apachectl
httpd=${HTTPD-/usr/local/apache/bin/httpd}
CONFFILE=/usr/local/apache/conf/httpd.conf

然后
chkconfig --add apachehttpd
如果你要运行在多个runlevel，比如3和5
chkconfig --level 35 apachehttpd on

附各个run level:

* rc0.d - System Halted
* rc1.d - Single User Mode
* rc2.d - Single User Mode with Networking
* rc3.d - Multi-User Mode - boot up in text mode
* rc4.d - Not yet Defined
* rc5.d - Multi-User Mode - boot up in X Windows
* rc6.d - Shutdown & Reboot


确认安装：
cd /etc/rc.d/rc3.d
you should see S85apachehttpd
cat S85apachehttpd
should show you the script

reboot and you should see the web page
