【轉】【CentOS】【Python】Centos7安裝Python3的方法

因爲centos7本來就安裝了Python2,並且這個Python2不能被刪除,由於有不少系統命令,好比yum都要用到。html

[root@VM_105_217_centos Python-3.6.2]# python
Python 2.7.5 (default, Aug  4 2017, 00:39:18)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-16)] on linux2
Type "help", "copyright", "credits" or "license" for more information.

輸入Python命令,查看能夠得知是Python2.7.5版本python

輸入mysql

which python

能夠查看位置,通常是位於/usr/bin/python目錄下。linux

下面介紹安裝Python3的方法sql

首先安裝依賴包centos

yum -y groupinstall "Development tools"
yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel

而後根據本身需求下載不一樣版本的Python3,我下載的是Python3.6.2服務器

wget https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tar.xz

#其餘版本地址:https://www.python.org/ftp/python/

若是速度不夠快,能夠直接去官網下載,利用WinSCP等軟件傳到服務器上指定位置,個人存放目錄是/usr/local/python3,使用命令:測試

mkdir /usr/local/python3 

創建一個空文件夾centos7

而後解壓壓縮包,進入該目錄,安裝Python3spa

tar -xvJf  Python-3.6.2.tar.xz
cd Python-3.6.2
./configure --prefix=/usr/local/python3
make && make install

最後建立軟連接

ln -s /usr/local/python3/bin/python3 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3

在命令行中輸入python3測試

 安裝 mysql:

pip3 install mysqlclient
