Q&A

forbedden 403

第一种方法给文件夹加上权限，第二种方法切换一个更高级别的账号

当然我更建议使用第一种

chmod -R 777 /data
chmod -R 777 /data/www

还不行的话尝试关闭 selinux，具体操作如下：

vi /etc/selinux/config

 #SELINUX=enforcing
 SELINUX=disabled

Could not resolve host: mirrorlist.centos.org Centos 7

第一步：进入 /etc/resolv.conf

加入文件配置内容如下：

nameserver 9.9.9.9

loaded plugins: fastestmirror, langpacks loading mirror speeds from cached hostfile

1.修改插件的配置文件

# vi /etc/yum/pluginconf.d/fastestmirror.conf

将 enabled=1 改为 enabled=0

2.修改 yum 的配置文件

# vi /etc/yum.conf

将 plugins=1 改为 plugins=0
