CentOS7安装python3.13步骤

1.下载python3.13

cd /opt/software
wget https://mirrors.huaweicloud.com/python/3.13.3/Python-3.13.3.tgz
tar -zxvf Python-3.13.3.tgz # 解压

2.安装依赖环境

yum -y install libffi-devel zlib zlib-dev zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel mysql-devel readline-devel tk-devel libffi libffi-devel gcc gcc-c++ make

3.openssl高版本安装

 wget http://www.openssl.org/source/openssl-1.1.1.tar.gz
         
        tar -zxvf openssl-1.1.1.tar.gz              解压对应版本安装包
         
        cd openssl-1.1.1                            进入对应的解压目录
         
        ./config --prefix=/usr/local/openssl shared zlib   (prefix为配置安装目录，shared zlib 安装依赖库）这一步最重要，一定要shared
         
        make && make install                        编译、安装

4.设置环境变量LD_LIBRARY_PATH

 echo "export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/openssl/lib" >>  /etc/profile    
         
(在系统环境变量文件中添加openssl的环境变量)
         
source /etc/profile      （重新加载该路径下的系统环境变量文件）

 5.安装python

编译环境准备好后，cd到Python源码安装目录下

然后执行configure文件：

./configure --prefix=安装路径 --with-openssl=/usr/local/openssl  

6.编译、测试，安装

make #编译
make test # 测试
make install 安装

 7.验证是否安装成功

cd /opt/module/python3.13/bin
 ./python3.13 --version # 测试python
 ./pip3.13 install pymysql # 测试pip
