CentOS升级Python

1. 安装前的准备

    yum install gcc-c++ make -y
   

2. 安装Python-3.8.0

    wget https://www.python.org/ftp/python/3.8.0/Python-3.8.0.tgz
    tar -zxvf Python-3.8.0.tgz
    cd Python-3.8.0
    ./configure --prefix=/usr/local/python
    make
    make install
   

3. 修改目录权限

    useradd www
    chown -R www:www /usr/local/python
   

4. 为新安装的python设置软连接到环境变量可及的目录

    ln -s /usr/local/python/bin/python3 /usr/bin/python3
   

5. 测试升级是否成功

    python3 -V
    python3 --version
