Alpine Linux 安裝 python3

1.進入容器內部, linux安裝python3環境

root@cb8e397d5308:/var/jenkins_home# cd /var/jenkins_home/
root@cb8e397d5308:/var/jenkins_home# mkdir python3
root@cb8e397d5308:/var/jenkins_home# cd python3/
root@cb8e397d5308:/var/jenkins_home/python3# wget https://www.python.org/ftp/python/3.8.0/Python-3.8.0.tgz
root@cb8e397d5308:/var/jenkins_home/python3# tar -xvf Python-3.8.0.tgz
root@cb8e397d5308:/var/jenkins_home/python3# ls
Python-3.6.8  Python-3.6.8.tgz
root@cb8e397d5308:/var/jenkins_home/python3# cd Python-3.8.0
root@cb8e397d5308:/var/jenkins_home/python3/Python-3.8.0# ./configure --prefix=/var/jenkins_home/python3 --with-ssl

報錯安裝依賴
2.解壓，下載依賴

下載依賴
apt-get -y install gcc automake autoconf libtool make
apt-get -y install make*
apt-get -y install zlib*
apt-get -y install openssl libssl-dev
apt-get install sudo
或
apk add build-base      //install GCC on Alpine Linux， apk add是安裝命令，不同Linux，命令不同
apk add zlib-dev           //install zlib-devel

解壓進入
tar xvf Python-3.8.0.tgz
cd Python-3.8.0

3.make編譯安裝
解壓完之后需要編譯Python-3.8.0包下的文件，先cd過去執行完這句命令之后，把python的安裝目錄指定一下，這樣的話，里面的一些bin目錄、lib目錄就都會存放在這個目錄下面。
如果不指定這個安裝目錄的話，最后python的安裝文件將分散到linux的默認目錄，不在一塊。我們指定安裝目錄，以后卸載的話直接刪除目錄就可以干凈卸載了。

./configure --prefix=/var/jenkins_home/python3 --with-ssl
make
make install

4.添加軟連接
由於系統默認的python是指向python2，這里執行把新安裝的python3.8指向給/usr/bin/python3就可以了

添加python3軟鏈接
ln -s  /var/jenkins_home/python3/bin/python3.8 /usr/bin/python3
添加pip3軟鏈接
ln -s  /var/jenkins_home/python3/bin/pip3 /usr/bin/pip3

5.檢察環境

python3
pip3
