Python-3.8.16.tgz
Centos7下安装python3.8
1.安装依赖
| yum groupinstall -y "Development Tools"
yum install -y wget zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make libffi-devel
|
2.下载python
| wget https://www.python.org/ftp/python/3.8.16/Python-3.8.16.tgz
|
3.解压
| tar -zxvf Python-3.8.16.tgz
|
4.编译安装

cd Python-3.8.16
#编译配置(配置安装目录)
./configure --prefix=/usr/local/python38 --with-openssl=/usr/local/openssl
# 指定编译文件的存放目录（安装目录）
# --prefix=/root/Python-3.8.16
# 待openssl包编译，否则pip install组件的时候，会无法下载https的组件
# --with-openssl=/usr/local/openssl
#编译
make && make install

ln -sf /usr/local/python38/bin/python3.8 /usr/bin/python
# 查看软连接是否设置好了
ll /usr/bin/python*
ll /usr/bin/pip*
# 查看python是否安装成功
python3 -V
pip3 -V

6.配置python国内安装源
python的官方包安装源在境外，所以导致pip install的时候，会非常慢。 我们可以选择国内的安装源，以此来加快安装速度。这里用的是阿里云的pypi源。
| #创建pip的配置文件
mkdir -p ~/.pip
cat <<EOF >> ~/.pip/pip.conf
# 配置pip.conf
[global]
index-url = http://mirrors.aliyun.com/pypi/simple/
[install]
trusted-host = mirrors.aliyun.com
EOF

还原yum配置中的python改为python2，防止异常

2.解压python后
进入解压目录
3.配置编译目录
| ./configure --prefix=编译目录
