Centos下安裝Python3.6

標籤：Linux   centos   Python3.6   

一、安裝python3.6.1
1、安裝依賴環境
#yum install readline-devel ##必須安裝否則會出現python3編譯器中不能使用退格鍵和方向鍵
2、下載安裝包並解壓
[[email protected] ~]# wget https://www.python.org/ftp/python/3.6.1/Python-3.6.1.tgz ##下載安裝包
[[email protected] ~]# tar zvxf Python-3.6.1.tgz ##解壓安裝包
3、 編譯並安裝
[[email protected] ~]# cd Python-3.6.1 ##進入安裝包
[[email protected] Python-3.6.1]# mkdir /usr/local/python3 ##建立安裝目錄
[[email protected] Python-3.6.1]# ./configure --prefix=/usr/local/python3 ##編譯
[[email protected] Python-3.6.1]# make && make install ##安裝
4、建立軟串連
[[email protected] Python-3.6.1]# mv /usr/bin/python /usr/bin/python_bak ##備份原軟串連
[[email protected] Python-3.6.1]# ln -s /usr/local/python3/bin/python3 /usr/bin/python ##chua建立新的軟連結使程式運行時不顯示版本號碼
5、測試軟體能否正常運行
[[email protected] Python-3.6.1]# python
Python 3.6.1 (default, Apr 21 2018, 16:42:07)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-18)] on linux
Type "help", "copyright", "credits" or "license" for more information.

6、將/usr/local/python3/bin加入到環境變數
[[email protected] Python-3.6.1]# vim ~/.bash_profile
PATH=$PATH:$HOME/bin:/usr/local/python3/bin
[[email protected] Python-3.6.1]# source ~/.bash_profile ##使環境變數生效
[[email protected] Python-3.6.1]# python3 -V ##測試python3正常
Python 3.6.1
[[email protected] Python-3.6.1]# pip3 -V ##測試pip3正常
pip 9.0.1 from /usr/local/python3/lib/python3.6/site-packages (python 3.6)
7、修改yum指向python 舊版本
[[email protected] pip-8.0.2]# vi /usr/bin/yum
#!/usr/bin/python2.6

二、安裝pip及setuptools
1、安裝pip前需要前置安裝setuptools
[[email protected] ~]# wget --no-check-certificate https://pypi.python.org/packages/source/s/setuptools/setuptools-19.6.tar.gz#md5=c607dd118eae682c44ed146367a17e26
[[email protected] ~]# tar zxvf setuptools-19.6.tar.gz
[[email protected] ~]# cd setuptools-19.6
[[email protected] ~]# python3 setup.py build
[[email protected] ~]# python3 setup.py install
2、安裝pip
[[email protected] ~]# wget --no-check-certificate https://pypi.python.org/packages/source/p/pip/pip-8.0.2.tar.gz#md5=3a73c4188f8dbad6a1e6f6d44d117eeb
[[email protected] ~]# tar zvxf pip-8.0.2.tar.gz
[[email protected] ~]# cd pip-8.0.2
[[email protected] pip-8.0.2]# python3 setup.py build
[[email protected] pip-8.0.2]# python3 setup.py install
