How to install Python under the linux6.5 version

Recently learning Python, because some modules in Linux can be more obvious effect, so on this machine with the Oracle VM Vitualbox installed a linux6.5 virtual machine. and the learning environment Python with 3.5+,linux is the 2.6.6, it needs to install a new version of the. The process is as follows (with Yum source configuration)

Virtual machine installation process is not detailed, mainly to configure the network this block, I set the host-only mode, and on the virtual machine configuration fixed IP, boot boot, using the Xmanager tool to connect. There is no big problem. Baidu is a problem.

---------------the split line, the entire process is logged into the root account below to get to the chase----------------

Steps:

1, download python3.6, and then upload with FTP tool.

2, use the command decompression, reference, can be replaced by your version TAR-ZXVF python-3.6.1.tgz

3, enter the directory, execute./configure--prefix=/usr/local/python3

An error occurred during this process, configure:error:no acceptable C compiler found in $PATH. After Baidu to view the problem, it should be GCC is not installed. Begin the process of configuring the Yum source to install GCC

---------------------------Yum configuration, gcc installation-----------------------

Because it is a virtual machine, it can be mounted directly on the disc,

The location of my disc mount here is/dev/cdrom,

Using the command mount/dev/cdrom/mnt, and then viewing under/mnt, the contents of the disc appear.

Configure the Yum source to rename the original repo file to the ***.repo1 file. The contents of my file are as follows, for reference only, if there is a problem, Baidu. Answer a lot, there is always a suitable for you:

　　

[Root@aaaddd software]# More/etc/yum.repos.d/dvd.repo [dvd]name=linux6.5baseurl=file:///mnt/servergpgcheck= 1ENABLE=1[ROOT@AAADDD software]#

Then execute yum clean to clear the Yum cache

Execute Yum Makecache to create a new cache

Then execute the Yum install GCC, encounter the prompt to enter Y, complete the installation. I encountered an error in this step, resolved (Baidu came to) as follows:

　　

Warning:rpmts_HdrFromFdno:Header V3 rsa/sha256 Signature, key ID fd431d51:nokeypublic key for cpp-4.4.7-4.el6.i686.rpm is not installed[root@aaaddd python-3.6.1]# [root@aaaddd python-3.6.1]# [root@aaaddd python-3.6.1]# [root@aaaddd python-3.6.1]# rpm--IMPORT/ETC/PKI/RPM-GPG/RPM*[ROOT@AAADDD python-3.6.1]#

Then execute the Yum install GCC and finish installing the

----------------------------continue with the Python installation-------------------------------------------

Go to Python installation file directory execution./configure--prefix=/usr/local/python3 (--prefix=/usr/local/python3 is the installation path, recommended)

Enter make &&make install after execution is complete

If the process also occurs, such as less packet, the direct yum install can be. Don't know the name can add *

Last: The most important thing is to add a soft connection, otherwise you cannot start Python3 "This is the disadvantage of the specified path."

Ln-s/usr/local/python3/bin/python3/usr/bin/python3

Once this is done, you can enter Python3 to start.
