linux 安装python

1、先查看系统python所在位置

[root@localhost ~]# whereis python
python: /usr/bin/python /usr/bin/python2.7 /usr/lib/python2.7 /usr/lib64/python2.7 /etc/python /usr/include/python2.7

可确认系统原python环境在/usr/bin/下。

2、进入/usr/bin/

cd /usr/bin/

3、先安装相关依赖

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

4、没有安装pip,需先添加epel扩展源

yum -y install epel-release

5、安装pip

yum install python-pip

6、下载python包(例如:Python3.10)
(注:若Linux环境网络好,可以直接下载;也可以通过其他方式下载后,在上传到Linux目录下)

wget https://www.python.org/ftp/python/3.10.9/Python-3.10.9.tgz

7、解压安装包

tar -xf Python-3.10.9.tgz

8、进入解压后的python目录,编译安装

cd Python-3.10.9

./configure prefix=/usr/local/python3

make && make install

9、安装依赖zlib、zlib-deve

yum install zlib zlib
yum install zlib zlib-devel

10、添加软连接

# 先备份原来的软连接
mv /usr/bin/python /usr/bin/python.bak
ln -s /usr/local/python3/bin/python3.10 /usr/bin/python

11、查看安装是否成功

python -V

完成!!!
