How to install python under linux6.5 version
I recently learned Python. Since some modules are more effective under Linux, I installed a Linux 6.5 virtual machine on this machine using Oracle VM VitualBox. The learning environment Python uses 3.5+, and Linux comes with 2.6.6, so you need to install the new version. . The process is as follows (with yum source configuration)
I won’t go into details about the virtual machine installation process. The main thing is to configure the network. I set the host-only mode, and configured a fixed IP on the virtual machine, and started it. , use the xmanager tool to connect. No big deal. If you have any questions, please call Baidu.
---------------Separating line, the entire process is logged in with the root account. Now let’s get to the point----------------
Steps:
1. Download python3.6, and then upload it using the FTP tool.
2. Use the command to decompress. For reference, you can change it to your version tar -zxvf Python-3.6.1.tgz
3. Enter the directory and execute ./configure --prefix=/ usr/local/python3
An error occurred during this process, configure: error: no acceptable C compiler found in $PATH. After checking the problem on Baidu, it should be that gcc is not installed. Start entering the process of configuring the yum source and installing gcc
---------------------------yum configuration, gcc installation-- ---------------------
Since it is a virtual machine, you can mount the CD directly.
I will mount the CD here The download location is /dev/cdrom,
Use the command mount /dev/cdrom /mnt, and then check under /mnt, the contents of the CD appear.
Configure the yum source and rename the original repo file to ***.repo1 file. The content of my file is as follows, for reference only. If there are any questions, please contact Baidu. There are many answers, there is always one 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 yum install gcc and enter y when prompted to complete the installation. I encountered an error in this step, and the solution (from Baidu) is as follows:
warning: rpmts_HdrFromFdno: Header V3 RSA/SHA256 Signature, key ID fd431d51: NOKEY Public 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 yum install gcc, and the installation is completed
-------------------------------Continue python installation----------------- --------------------------
Enter the python installation file directory and execute ./configure --prefix=/usr/local/ python3 (--prefix=/usr/local/python3 indicates the installation path, it is recommended to write it)
After the execution is completed, enter make &&make install
If there are still some situations such as missing packages during the process , just yum install. If you don’t know the name, you can add *
Finally: The most important thing is to add a soft link, otherwise python3 cannot be started [This is the disadvantage of specifying the path]
ln -s /usr/ local/python3/bin/python3 /usr/bin/python3
After this step is completed, you can enter python3 to start.
