CentOS Update python

1. CentOS Install Python dependency package

Yum Groupinstall "Development tools"
Yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel Libpcap-devel Xz-devel

2, download the Python3.4 source package and compile

wget https://www.python.org/ftp/python/3.4.1/Python-3.4.1.tgz
Tar XF python-3.4.1.tgz
CD Python-3.4.1
./configure--prefix=/usr/local--enable-shared
Make
Make install

3. You need to configure the library before running Python:

Echo/usr/local/lib >>/etc/ld.so.conf.d/local.conf
Ldconfig

4. Run the Demo:

Python3--version
Python 3.4.1

5. Delete the libraries needed to compile Python

Yum Groupremove "Development tools"--remove-leaves
Yum Remove Zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel L Ibpcap-devel Xz-devel--remove-leaves

6, establish a soft connection, so that the system default Python point to python3.4

mv/usr/bin/python/usr/bin/python2.6.6

Ln-s/usr/local/bin/python3.4/usr/bin/python
