将apache安装为系统服务
# cp /usr/local/apache2/bin/apachectl /etc/rc.d/init.d/httpd
然后 vi /etc/rc.d/init.d/httpd 添加(#!/bin/sh下面)
# chkconfig: 2345 50 90
# description: Activates/Deactivates Apache Web Server
最后，运行chkconfig把Apache添加到系统的启动服务组里面：
# chkconfig –add httpd
# chkconfig httpd on
然后再service httpd start
