0x1，安装

百度：Nessus，随意下载一个就好了.

0x2，激活

开启代理，获取register code，如图：

获取到register code，填写，进行激活，意外报错：

NOTICE: An unexpected error occurred while downloading the plugins. This could be due to a network error, lack of disk space, or something else entirely. Please take one of the following corrective actions:

Run the 'nessuscli update' command for your respective platform.

Request help from [Tenable Customer Support]

原来：在更新plugins时，没有关闭代理，从而导致报错.

0x3，更新

此时，关闭代理，使用命令行更新plugins：nessuscli update

ps：一定要保持网络畅通，因为Nessus需要下载plugins&unpacking plugins.

更新plugins完成，这样，就可以了.
