1.检查当前python版本

python -v

2.下载最新的python

python下载地址：

wget https://www.python.org/ftp/python/3.12.2/Python-3.12.2.tar.xz

• 进行解压

tar -xvf Python-3.12.2.tar.xz

• 系统更新并安装依赖包

yum update -y
yum install -y make gcc gcc-c++

• 进行编译

cd Python-3.12.2
./configure

• 进行安装

make
make install

• 将原来的python的软连接重命名：

mv /usr/bin/python /usr/bin/python.bak

• 添加软链

ln -s /data/tool/Python-3.12.2/python /usr/bin/python

3. pip安装

wget https://bootstrap.pypa.io/get-pip.py

4.系统默认python调整

• 修改为python2.7

vim /usr/bin/yum
#!/usr/bin/python2.7

5 .错误

• Could not fetch URL https://pypi.org/simple/pip/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host=‘pypi.org’, port=443): Max retries exceeded with url: /simple/pip/ (Caused by SSLError(“Can’t connect to HTTPS URL because the SSL module is not available.”)) - skipping

安装 openssl-1.1.1
下载openssl1.1.1
 
wget https://www.openssl.org/source/openssl-1.1.1n.tar.gz --no-check-certificate 
解压
tar -zxf openssl-1.1.1n.tar.gz 
进入目录
cd openssl-1.1.1n
设置安装目录 可以自定义 但是要记住，后面会用到
./config --prefix=/data/software/openssl
编译并安装
make -j && make install 
 
 
cd /data/package/Python-3.11.5
make  clean
./configure --prefix=/data/software/python3 --with-openssl=/data/software/openssl --with-openssl-rpath=auto
make -j && make install
