python3.7.6安装

1. 安装必备依赖

sudo apt update
sudo apt install -y \
    build-essential \
    zlib1g-dev \
    libncurses5-dev \
    libgdbm-dev \
    libnss3-dev \
    libssl-dev \
    libreadline-dev \
    libffi-dev \
    wget \
    openssl \
    libffi-devel
# 安装 EPEL 仓库（推荐）
sudo yum install epel-release

# 安装常用 Python 开发依赖
sudo yum install python3 python3-pip python3-devel

# 安装编译 Python 时需要的系统依赖
sudo yum install gcc openssl-devel bzip2-devel libffi-devel zlib-devel

2. 下载 Python 3.7.6 源码

wget https://www.python.org/ftp/python/3.7.6/Python-3.7.6.tgz
tar -xzf Python-3.7.6.tgz
cd Python-3.7.6

3. 配置时显式指定 OpenSSL（关键步骤）

# 找到系统openssl的安装路径
openssl_dir=$(dirname $(dirname $(which openssl)))

# 配置时加入ssl参数
./configure \
    --enable-optimizations \
    --with-openssl=$openssl_dir \
    --enable-shared

这一步ssl配置不成功可以手动设置参数位置

# 如果系统有多个openssl版本，手动指定1.1.1版本路径
./configure \
    --with-openssl=/usr/include/openssl \
    --enable-optimizations

./configure \
    --with-openssl=/usr \
    --with-ssl-default-suites=openssl \
    --enable-loadable-sqlite-extensions

4. 编译安装

make -j$(nproc)
sudo make altinstall

加入环境变量

ln -s /usr/local/bin/python3.7 /usr/bin/python3.7
ln -s /usr/local/bin/pip3.7 /usr/bin/pip3.7

验证安装

python3.7 -c "import ssl; print(ssl.OPENSSL_VERSION)"
# 应该显示 OpenSSL 版本号

centos安装
环境依赖

yum -y update
yum install wget -y
yum install gcc gcc-c++ -y
yum install zlib-devel -y

下载Python

wget https://www.python.org/ftp/python/3.7.6/Python-3.7.6.tgz

安装Python

tar -zxvf Python-3.7.6.tgz
cd Python-3.7.6
./configure
./configure --enable-optimizations
make && make install

验证是否成功安装
加入环境变量

ln -s /usr/local/bin/python3.7 /usr/bin/python3.7
ln -s /usr/local/bin/pip3.7 /usr/bin/pip3.7
