This article is about how to install Python 3.5. Xiaobian thinks it is quite practical, so share it with everyone for reference. Let's follow Xiaobian and have a look.

1. Unpack

[root@monit Python]# tar -xzf Python-3.5.2.tgz

2 is moved

[root@monit Python]# mv Python-3.5.2 /usr

[root@monit usr]# mkdir SoftWare

[root@monit usr]# mv mysql-* SoftWare/

[root@monit usr]# mv Python-3.5.2/ SoftWare/

3 Compilation

[root@monit SoftWare]# cd Python-3.5.2/

[root@monit Python-3.5.2]#./ configure --prefix=/usr/local/python3

[root@monit Python-3.5.2]# make && make install

4 Setting environment variables

echo 'export PATH=$PATH:/usr/local/python3/bin' >> ~/.bashrc

4. Replace Python2

The purpose of this is to type python calls into any directory of the system that is python 3 commands, not the system default 2.6.6 commands. However, this will also cause yum that depends on python 2.6 to not be used, so you have to modify the yum configuration.

[root@monit bin]# rm /usr/bin/python

rm: remove regular file `/usr/bin/python'? y

[root@monit Python-3.5.2]# ln -sv /usr/local/python3/bin/python3.5 /usr/bin/python

At this point, under the/usr/bin directory is (ll), which contains the following files| grep python), which has a python 2.6, just need to specify yum configuration python point here

[root@monit bin]# ll /usr/bin | grep python

-rwxr-xr-x 1 root root 11040 Aug 14 2013 abrt-action-analyze-python

lrwxrwxrwx 1 root root 19 Aug 7 20:47 python -> /usr/local/python3/

lrwxrwxrwx. 1 root root 6 Aug 7 12:54 python2 -> python

-rwxr-xr-x 1 root root 9032 Sep 4 2013 python2.6

Modify yum configuration via vim #!/ /bin/python changed to #!/ /usr/bin/python2.6, save exit.

[root@monit bin]# vim /usr/bin/yum
