Alpine Linux 安装 python3

1.进入容器内部, linux安装python3环境

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

root@cb8e397d5308:/var/jenkins_home/python3# cd Python-3.8.0

报错安装依赖
2.解压，下载依赖

下载依赖
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是安装命令，不同Linux，命令不同
apk add zlib-dev           //install zlib-devel

解压进入
tar xvf Python-3.8.0.tgz
cd Python-3.8.0

3.make编译安装
解压完之后需要编译Python-3.8.0包下的文件，先cd过去执行完这句命令之后，把python的安装目录指定一下，这样的话，里面的一些bin目录、lib目录就都会存放在这个目录下面。
如果不指定这个安装目录的话，最后python的安装文件将分散到linux的默认目录，不在一块。我们指定安装目录，以后卸载的话直接删除目录就可以干净卸载了。

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

4.添加软连接
由于系统默认的python是指向python2，这里执行把新安装的python3.8指向给/usr/bin/python3就可以了

添加python3软链接
ln -s  /var/jenkins_home/python3/bin/python3.8 /usr/bin/python3
添加pip3软链接
ln -s  /var/jenkins_home/python3/bin/pip3 /usr/bin/pip3

5.检察环境

python3
pip3
