python安装

python3.6.12
python库
zlib1.3
openssl-1.1.1

1. 前置安装

python安装依赖于gcc、openssl-devel、zlib-devel
实际环境存在gcc环境,仅安装openssl-devel、zlib-devel
前置安装使用root用户操作

1.1 安装zlib

#下载openssl离线包(版本尽量为1.1.X)
#解压
tar -xvf openssl-1.1.1n.tar.gz
#编译
./config --prefix=/usr/local/openssl --openssldir=/usr/local/openssl
make && make install

#配置环境变量
vim ~/.bashrc
export LD_LIBRARY_PATH=/usr/local/openssl/lib:$LD_LIBRARY_PATH
export PATH=/usr/local/openssl/bin:$PATH

source ~/.bashrc
````  

## 2. python安装

````bash
#下载python
#解压
tar -xvf Python-3.6.12.tgz
cd Python-3.6.12
#编译和安装：
#执行以下命令进行编译和安装：
./configure --prefix=/usr/local/python3 --with-openssl=/usr/local/openssl --with-ssl
make && make install

报错查看
