conda create环境报错解决办法

conda create -n reco_sys python=3.6.7
报错：
CondaHTTPError: HTTP 000 CONNECTION FAILED for url https://repo.anaconda.com/pkgs/main/linux-64/python-3.6.7-h0371630_0.tar.bz2
Elapsed: -
An HTTP error occurred when trying to retrieve this URL.
HTTP errors are often intermittent, and a simple retry will get you on your way.

解决办法：
在当前用户目录下，如果是root用户则为/root，增加.condarc文件，内容如下：

(reco_sys) [root@hadoop-master ~]# cat .condarc 
channels:
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/msys2/
show_channel_urls: true

再次运行则正常。
