100%小白,完全不明白教程说的都是啥,更对docker没任何经验。所有操作都是按照教程一步步走下来,至这一步时报错:
[root@FuckGFW yii2_fecshop_docker]# docker-compose build
ERROR: Couldn't connect to Docker daemon at http+docker://localhost - is it running?
If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable.
[root@FuckGFW yii2_fecshop_docker]#
看文字似乎是说docker daemon没启动?
接下来应如何应对呢?
