centos7 編譯安裝python3.7.1

 安裝步驟

centos7自帶python2,由於執行yum需要python2,所以即使安裝了python3也不能刪除python2
1.安裝依賴包
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 libffi-devel

2.下載自己需要的python版本,例如python3.7.1,下載要花費一段時間,要耐心等待

yum -y install wget
wget https://www.python.org/ftp/python/3.7.1/Python-3.7.1.tar.xz

3.新建一個資料夾存放python3
mkdir /usr/local/python3 

4.把安裝包移動到該新建資料夾下,解壓安裝包,安裝python3,依次執行以下命令,花費時間較長,耐心等待

mv Python-3.7.1.tar.xz /usr/local/python3
tar -xvJf  Python-3.7.1.tar.xz
cd Python-3.7.1
./configure --prefix=/usr/local/python3
make  
make install

 

5.建立軟連線
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3

6.此時python3已經裝好,在命令列中輸入python3測試


7.修改yum配置檔案,python2與python3共存
vi /usr/bin/yum

把#! /usr/bin/python修改為#! /usr/bin/python2(配置檔案第一行)
同理
vi /usr/libexec/urlgrabber-ext-down

把檔案裡面的#! /usr/bin/python 也修改為#! /usr/bin/python2
此時完成python3安裝,且實現與python2共存,保持yum命令可用

下面是Ubuntu配置:

sudo apt-get install gcc

sudo apt-get install zlib1g-dev libbz2-dev libssl-dev libncurses5-dev libsqlite3-dev libreadline-dev tk-dev libgdbm-dev libdb-dev libpcap-dev xz-utils libexpat1-dev liblzma-dev libffi-dev libc6-dev

安裝好之後將一些檔案開頭改成系統的python版本,避免衝突

vim /usr/lib/command-not-found

vim /usr/bin/gnome-terminal

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 libffi-devel

開發工具包組沒安裝上,下面的包都裝上了

2.下載自己需要的python版本,例如python3.7.1,下載要花費一段時間,要耐心等待

yum -y install wget
wget https://www.python.org/ftp/python/3.7.1/Python-3.7.1.tar.xz

4.把安裝包移動到該新建資料夾下,解壓安裝包,安裝python3,依次執行以下命令,花費時間較長,耐心等待

mv Python-3.7.1.tar.xz /usr/local/python3

cd  /usr/local/python3
tar -xJf  Python-3.7.1.tar.xz
cd Python-3.7.1
./configure --prefix=/usr/local/python3
make  
make install

 

5.建立軟連線
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3

6.此時python3已經裝好,在命令列中輸入python3測試

7.(可選,我沒做)修改yum配置檔案,python2與python3共存
vi /usr/bin/yum

把#! /usr/bin/python修改為#! /usr/bin/python2(配置檔案第一行)
同理
vi /usr/libexec/urlgrabber-ext-down

把檔案裡面的#! /usr/bin/python 也修改為#! /usr/bin/python2
此時完成python3安裝,且實現與python2共存,保持yum命令可用

下面是Ubuntu配置:

sudo apt-get install gcc

sudo apt-get install zlib1g-dev libbz2-dev libssl-dev libncurses5-dev libsqlite3-dev libreadline-dev tk-dev libgdbm-dev libdb-dev libpcap-dev xz-utils libexpat1-dev liblzma-dev libffi-dev libc6-dev

安裝好之後將一些檔案開頭改成系統的python版本,避免衝突

vim /usr/lib/command-not-found

vim /usr/bin/gnome-terminal

 8、將編譯好的python3遷移到主機2中使用

檢視主機2,確認沒有

 只需要編譯安裝產生的檔案,不需要壓縮包和解壓檔案

 新主機中檢查沒有python3,建立軟連線。

 還是沒有

 連結錯地方了,額,我是放到opt下面了。重新建立連結就可以了。

 寫個程式都是正常執行
