CentOS 6 Installation Python3.5

Installing Python3.5

1. Preparing the Environment for compilation

Yum Groupinstall ' development tools ' yum install yum install zlib-devel bzip2-devel openssl-devel ncurses-devel Sqlite-dev Elreadline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel

2. Download the installation package

Wget

3. Compiling

Tar XF python-3.5.0.tgz cd Python-3.5.0./configure--prefix=/usr/local/python3 make do install

4. Setting Environment variables

Echo ' Export path= #PATH:/usr/local/python3/bin ' >> ~/.BASHRC

5. Replace Python2

Rm/usr/bin/pythonln-sv/usr/local/bin/python3.5/usr/bin/python

(This is done by typing the python3.5 command in any directory of the system, not the system default of 2.6.6.) However, this will result in the python2.6-dependent yum not being used and therefore also modifying the Yum configuration)

6. Updating the Yum configuration

Ll/usr/bin | grep python

(The/usr/bin directory below contains the following files (ll | grep python), where there is a python2.6, just specify the yum configuration for Python to point to here)

Vim/usr/bin/yum

change yum configuration via Vim, #!/usr/bin/python to #!/usr/bin/python2.6, save exit, complete Python3 installation

7. Run Python
