我已经在CentOS 7上安装了docker，运行如下命令:
curl -sSL https://get.docker.com/ | sh
systemctl enable docker && systemctl start docker
docker run hello-world
注意:helloworld运行正常，没有问题。
然而，当我试图运行docker-compose (docker-compose。yml存在并且有效)它只在CentOS上给了我错误(Windows版本的docker-compose文件工作良好)
/usr/local/bin/docker-compose: line 1: {error:Not Found}: command not found
当前回答
安装docker并不意味着你已经安装了docker-compose。它有一个先决条件，那就是你已经安装了docker引擎。之后，你可以按照这个链接为Centos 7安装docker-compose。

参考上面给出的答案(我没有足够的声誉单独提到单独的解决方案，因此我在这里集体做这些)，我想补充一些重要的建议:
docker-compose you can install from the repository (if you have this package in the repository, if not you can adding to system a repository with this package) or download binary with use curl - totourial on the official website of the project - src: https://docs.docker.com/compose/install / docker-compose from the repository is in version 1.8.0 (at least at me). This docker-compose version does not support configuration files in version 3. It only has version = <2 support. Inthe official site of the project is a recommendation to use container configuration in version 3 - src: https://docs.docker.com/compose/compose-file / compose-versioning /. From my own experience with work in the docker I recommend using container configurations in version 3 - there are more configuration options to use than in versions <3. If you want to use the configurations configurations in version 3 you have to do update / install docker-compose to the version of at least 1.17 - preferably the latest stable. The official site of the project is toturial how to do this process - src: https://docs.docker.com/compose/install/ when you try to manually remove the old docker-compose binaries, you can have information about the missing file in the default path /usr/local/bin/docker-compose. At my case, docker-compose was in the default path /usr/bin/docker-compose. In this case, I suggest you use the find tool in your system to find binary file docker-compose - example syntax: sudo find / -name 'docker-compose'. It helped me. Thanks to this, I removed the old docker-compose version and added the stable to the system - I use the curl tool to download binary file docker-compose, putting it in the right path and giving it the right permissions - all this process has been described in the posts above.

您还需要安装Docker Compose。请参阅说明书。下面是您需要执行的命令
sudo curl -L "https://github.com/docker/compose/releases/download/v2.12.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo mv /usr/local/bin/docker-compose /usr/bin/docker-compose
sudo chmod +x /usr/bin/docker-compose
注意: 确保指向GitHub版本的链接没有过时!在GitHub上查看最新版本。
我在debian上，我发现了一些很自然的事情:
apt-get install docker-compose
它做到了 (未测试centos)
首先请检查docker-compose是否安装，
$ docker-compose -v
如果没有安装，请参考安装指南https://docs.docker.com/compose/install/ 如果安装，则给予二进制文件可执行权限。
$ chmod +x /usr/local/bin/docker-compose
检查一下是否有效。
如果docker-compose已经存在于/usr/local/bin中:
ls -alt /usr/local/bin/ | grep docker-compose
> lrwxr-xr-x 1 root wheel 77 Mar 11 10:39 docker-compose -> /Applications/Docker.app/Contents/Resources/bin/docker-compose/docker-compose
最后用/usr/local/bin更新你的.bash_profile路径:
export PATH="$HOME/.yarn/bin:$HOME/.config/yarn/global/node_modules/.bin:$PATH:/usr/local/bin"
Run:
source ~/.bash_profile
并检查:
echo $PATH
> ...
which docker-compose
> /usr/local/bin/docker-compose
docker-compose
