1. Install the dependency package 1. Install the gcc compiler first. Some system versions of gcc have been installed by default. Check through gcc-version. Install gcc,yum-y install gcc first if not installed.

2. Install other dependent packages. (note: do not lack it, otherwise there may be errors in installing python. Versions below python3.7.0 may not install libffi-devel.)

Yum-y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel libffi-devel

Second, download the python3.7.0 source code. 1. Select the python source code package you need in https://www.python.org/ftp/python/. I downloaded python3.7.0 (you can also download it from the home page of the https://www.python.org official website, find downloads, and you can choose the version you want to download).

2. Download

Wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz

3. Decompress Python-3.7.0.tgz

Tar-zxvf Python-3.7.0.tgz

4. Create an empty folder for storing python3 programs

Mkdir / usr/local/python3

5. Execute configuration file, compile, compile and install

Cd Python-3.7.0. / configure-- prefix=/usr/local/python3 make & & make install installation completed without error and installed successfully

6. Establish a soft connection

Ln-s / usr/local/python3/bin/python3.7 / usr/bin/python3 ln-s / usr/local/python3/bin/pip3.7 / usr/bin/pip37, test whether python3 can be used

[root@mini Python-3.7.0] # python3 Python 3.7.0 (default, Jul 28 2018, 22:47:29) [GCC 4.8.5 20150623 (Red Hat 4.8.5-28)] on linux Type "help", "copyright", "credits" or "license" for more information. > print ("hello world!")
