39-Linux下安装python

1. 安装依赖

yum install wget zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make zlib zlib-devel libffi-devel -y

2. wget 远程下载

该页面用户获取下载地址：
https://www.python.org/downloads/release/python-3104/wget https://www.python.org/ftp/python/3.10.4/Python-3.10.4.tgz

3. 存文件解压缩

export/server 下面 

tar -xvf Python-3.10.4.tgz

切换到python目录下 cd Python-3.10.4

4. 执行配置

./configure --prefix=/export/server/python3.10.4

5.编译并安装

make && make install 

6.安装好以后的操作命令行

[root@node1 Python-3.10.4]# cd /export/server/python3.10.4/

>>> exit()
[root@node1 bin]# vi编辑器进入后 
分别在
/usr/libexec/urlgrabber-ext-down
和
/usr/bin/yum
两个编辑的文件中的第一行末尾 添加数字2
保存即可
到这一步就完成linux系统的python完美安装
同时不影响yum的使用
任意位置输入python命令即可使用python命令即可使用解释器 
预祝大家安装顺利!
