修改配置文件
# cd
/etc/httpd/conf
# ls
httpd.conf
magic
#cp httpd.conf httpd.conf.origin //将原有配置文件备份
# more httpd.conf
//查看配置文件,我们注意到以一配置：
DocumentRoot"/var/www/html"
//特别是要注意这个配置
//这是Apache 2.4的一个新的默认值，拒绝所有的请求！
<Directory />
AllowOverride none
Require all denied
</Directory>
//设置为自动启动
# systemctl enable httpd.service
ln -s'/usr/lib/systemd/system/httpd.service' '/etc/systemd/system/multi-user.target.wants/httpd.service'
//在centos7中chkconfig httpd on 被替换成 systemctl enable httpd
配置WEB站点 （假设使用/wwwroot目录下的文档）
//创建两个网站的目录结构及测试用页面文件
# mkdir/wwwroot/www
# echo"www.linux.local" > /wwwroot/www/index.html
# mkdir/wwwroot/crm
# echo"crm.linux.local" > /wwwroot/crm/index.html
//配置虚拟机主机
# cd/etc/httpd/
# mkdirvhost-conf.d
# echo"Include vhost-conf.d/*.conf" >> conf/httpd.conf
# vi/etc/httpd/vhost-conf.d/vhost-name.conf
//添加如下内容
<VirtualHost *:80>

DocumentRoot /wwwroot/www/
</VirtualHost>
<Directory /wwwroot/www/>
Requireall granted
