Ubuntu下docker以及docker-compose安装
Docker
// 使用官方脚本自动安装
curl -fsSL https://test.docker.com -o get-docker.sh
sudo sh get-docker.sh
如果要使用 Docker 作为非 root 用户，则应考虑使用类似以下方式将用户添加到 docker 组：
$ sudo usermod -aG docker your-user
卸载 docker
删除安装包：
sudo apt-get purge docker-ce
删除镜像、容器、配置文件等内容：
sudo rm -rf /var/lib/docker
使用 Pip 安装 Docker Compose
或许，我们可以使用 Pip 安装 Docker Compose 。Pip 是 Python 包管理器，用来安装使用 Python 编写的应用程序。
参考下列链接安装 Pip 。
安装 Pip 后，运行以下命令安装 Docker Compose。下列命令对于所有 Linux 发行版都是相同的！
复制
$ pip install docker-compose
安装 Docker Compose 后，使用下列命令检查版本：
复制
$ docker-compose --version
你将会看到类似下方的输出：
复制
docker-compose version 1.29.2, build unknown
我在服务器上使用pip安装Python的库时直接报错，即使输入pip 也会直接报错，报错如下：
File "/usr/lib/python3/dist-packages/OpenSSL/__init__.py", line 8, in <module>
from OpenSSL import crypto, SSL
File "/usr/lib/python3/dist-packages/OpenSSL/crypto.py", line 1553, in <module>
class X509StoreFlags(object):
File "/usr/lib/python3/dist-packages/OpenSSL/crypto.py", line 1573, in X509StoreFlags
CB_ISSUER_CHECK = _lib.X509_V_FLAG_CB_ISSUER_CHECK
AttributeError: module 'lib' has no attribute 'X509_V_FLAG_CB_ISSUER_CHECK'
问题原因
pyOpenSSL版本与python版本不匹配
解决方法
# 卸载pip
sudo apt-get remove python3-pip
# 下载pip
wget https://files.pythonhosted.org/packages/4b/30/e15b806597e67057e07a5acdc135216ccbf76a5f1681a324533b61066b0b/pip-22.2.2.tar.gz
# 解压
tar xf pip-22.2.2.tar.gz
# 安装
cd pip-22.2.2
python3 setup.py install
# 查询版本
root@ubuntu:/home/ubuntu/# pip3 --version
pip 22.2.2 from /usr/local/lib/python3.8/dist-packages/pip-22.2.2-py3.8.egg/pip (python 3.8)
# 软连接
ln /usr/local/bin/pip /usr/bin/pip
安装匹配的 pyOpenSSL
root@ubuntu:/home/ubuntu/# pip3 install pyOpenSSL --upgrade
