在rc.local文件中添加/usr/local/apache/bin/apachectl start，然后输入:wq保存退出：vi /etc/rc.d/rc.local
#!/bin/bash
# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
#
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this file.
#
# In contrast to previous versions due to parallel execution during boot
# this script will NOT be run after all other services.
#
# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
# that this script will be executed during boot.
touch /var/lock/subsys/local
/usr/local/apache/bin/apachectl start2.9 设置环境变量
编辑root环境变量：vi /root/.bash_profile
在PATH路径后添加：:/usr/local/apache/bin
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin:/usr/local/apache/bin
export PATH使环境变量生效：source /root/.bash_profile
三、验证
浏览器页面输入：http://ip
如果打不开，确认防火墙是否关闭，没有的话，禁用防火墙
