python安装

3.9.6

在 Red Hat 7.6 系统上编译和安装 Python 3.9.6，你可以按照以下步骤操作：

步骤：

1. 安装必要的依赖项

sudo yum groupinstall -y "Development Tools" （没有不装）
sudo yum install -y zlib-devel ncurses-devel gdbm-devel nss-devel openssl-devel readline-devel sqlite-devel bzip2-devel libffi-devel wget

2. 下载 Python 3.9.6 源代码

wget https://www.python.org/ftp/python/3.9.6/Python-3.9.6.tgz

3. 解压源代码包

tar -zxvf Python-3.9.6.tgz
cd Python-3.9.6
vim Modules/Setup,  放开注释

_ssl _ssl.c \
        -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
        -L$(SSL)/lib -lssl -lcrypto

4. 配置安装选项

./configure  --enable-shared   CFLAGS=-fPIC --enable-loadable-sqlite-extensions --prefix=/app/python3

• --enable-optimizations：启用编译优化，提高运行效率（慎用）

5. 编译和安装

make && make install
