    linux 安装 python3

    软件源

    1. 下载软件
      mkdir -p /soft 
      cd /soft 
      wget https://www.python.org/ftp/python/3.6.6/Python-3.6.6.tgz
      yum install sqlite-devel
    2. 安装
      tar xf Python-3.6.6.tgz
      cd Python-3.6.6
      mkdir -p /usr/local/python3
      ./configure --prefix=/usr/local/python3
      make && make install
    3. 配置环境变量

      ln -s /usr/local/python3/bin/python3 /usr/bin/python3
      vim ~/.bash_profile
      PATH=$PATH:$HOME/bin:/usr/local/python3/bin
      source ~/.bash_profile
    4. ssl相关

    python在使用时,可能会使用ssl模块。所以在编译时,可以直接将ssl模块编译进去。

    yum install openssl
    yum install openssl-devel -y
    cd Python-3.6.6
    vi Modules/Setup #修改文件如下
    
        # Socket module helper for socket(2)
        _socket socketmodule.c
    
        # Socket module helper for SSL support; you must comment out the other
        # socket line above, and possibly edit the SSL variable:
        SSL=/usr/local/ssl
        _ssl _ssl.c \
            -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
            -L$(SSL)/lib -lssl -lcrypto
    
    然后进行编译安装即可
