Server configuration Python3.6

The python environment on the newly built Tencent Cloud server is only 2.7, but many systems currently use python3.6 and above.

1. View python and dependencies

// 切换目录
cd /usr/bin/

// 查看python文件
ls python*      // output: python python2 python2.7

// 查看依赖关系
ls -al python*  // output: 发现python默认指向python2，python2指向python2.7

2. Download the source code and unzip it

// 创建并切换目录
mkdir /usr/local/python3
cd /usr/local/python3

// 下载源码压缩文件
wget https://www.python.org/ftp/python/3.6.3/Python-3.6.3.tgz

// 解压并查看当前目录
tar -xvf Python-3.6.3.tgz
ll      // output: 生成名为Python-3.6.3的目录

3.Compile

// 切换目录
cd Python-3.6.3

// 创建编译规则
./configure --prefix=/usr/local/python3Dir

// 编译
make
make install

4. Check whether the installation is successful

// 检查版本
python3 -V      // output: Python3.6.3
// 检查依赖关系
cd /usr/local/bin/
ls -al python*
