Linux 安裝docker-compose的兩種方法

方法一：PIP安裝

聽說推薦使用pip安裝docker-compose，因爲pip可以爲你自動對應版本問題

安裝pip

yum -y install epel-release
yum -y install python-pip

確認版本

pip --version

更新pip

pip install --upgrade pip

安裝docker-compose

pip install docker-compose 

查看版本

docker-compose version

如果執行報錯You are using pip version 8.1.2, however version 19.3.1 is available. You should consider upgrading via the 'pip install --upgrade pip' command.
根據提示執行：sudo pip install --upgrade pip，報錯如下：

ReadTimeoutError: HTTPSConnectionPool(host='files.pythonhosted.org', port=443):

pip install默認超時時間是15s，由於中國qiang的原因，在安裝的過程中可能會超時，所以我們在執行命令時，可顯式指定超時時間，如下：

pip --default-timeout=100 install --upgrade  pip

還是很慢？換國內源：

 pip install -i https://pypi.douban.com/simple pip

如果報錯：

ERROR: docker-compose 1.24.1 has requirement requests!=2.11.0,!=2.12.2,!=2.18.0,<2.21,>=2.6.1, but you'll have requests 2.22.0 which is incompatible.
ERROR: rtslib-fb 2.1.69 has requirement pyudev>=0.16.1, but you'll have pyudev 0.15 which is incompatible.
ERROR: ipapython 4.6.5 has requirement python-ldap>=3.0.0b1, but you'll have python-ldap 2.4.15 which is incompatible.

更新版本即可:

pip install  -i https://pypi.douban.com/simple  --upgrade pyudev

方法二

這個方法比較慢，畢竟從github上下載的。。。

#下載docket-compose
curl -L https://github.com/docker/compose/releases/download/1.25.0-rc4/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose

#修改權限
chmod +x /usr/local/bin/docker-compose

上github搜索docker compose，第一個進去找到releases模塊，各個版本的鏈接都在這https://github.com/docker/compose/releases。安裝提示安裝即可。
