.在httpd配置完成的情况下进行一下操作

#提前做一个软连接
[root@localhost ~]# echo  "export PATH=/usr/local/apachectl/bin:$PATH"  >  /etc/profile.d/httpd.sh
[root@localhost ~]# . /etc/profile.d/httpd.sh
[root@localhost ~]# apachectl start
#设置是否能访问
[root@localhost ~]# vim /etc/httpd24/httpd.conf

    AllowOverride none
    Require all denied



      
      Require all denied      #禁止任何服务器访问
      Require ip 192.168.86.137       #只允许访问192.168.86.137
      

相同IP相同端口不同域名
