wget https://www.python.org/ftp/python/3.6.6/Python-3.6.6.tgz

2. Download the dependency package compiled by python3

  yum install -y gcc patch libffi-devel python-devel  zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel

3. Unzip the source code package

tar -zxvf Python-3.6.6.tgz

4. Enter the source package folder

cd Python-3.6.6

5. Compile and install

2.ls View the source package content

3. Release the compiled file Makefile

./configure --prefix=/opt/python36   # 指定安装目录为/opt/python36

4 .Compile

 make   # 相当于把源码包里面的代码编译成linux服务器可以识别的代码

5. Compile and install, this step will finally generate /opt/python36/

  make install

Note: Steps 4 and 5 can be executed together, but you need to use && in between Separate

  make && make install  # 先进行make，执行完成之后，才开始执行make install

and enter the /opt directory to view the python36 folder. The python3 we want is all here

/opt/python36/bin/python3
  /opt/python36/bin/pip3
  .....

6. Change the path variable of linux and add python3

to modify it /etc/profile system environment variable configuration file, add the following content

vim  /etc/profile

 ~/.bash_profile  # 这个是用户环境变量配置文件
  /etc/profile  # 系统环境变量配置文件
  PATH=/opt/python36/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin

Note: Be sure to put the python3 directory in the first

7. In order to permanently take effect the path setting, add it to the /etc/profile global environment variable configuration file and reload the configuration file /etc/profile

source /etc/profile
