centos7下使用wget github资源，可能会报如下错误: Resolving github.com (github.com)... 20.205.243.166 Connecting to github.com (github.com)|20.205.243.166|:443... connected. Unable to establish SSL connection.

解决办法如下加上：--no-check-certificate 即可:

[root@worker1 local]# wget https://github.com/Dreamacro/clash/releases/download/v1.14.0/clash-linux-amd64-v1.14.0.gz --no-check-certificate
