一、安装依赖
#1.安装相关依赖
[root@prd-airflow001 ~]$ yum -y install zlib zlib-devel
[root@prd-airflow001 ~]$ yum -y install bzip2 bzip2-devel
[root@prd-airflow001 ~]$ yum -y install ncurses ncurses-devel
[root@prd-airflow001 ~]$ yum -y install readline readline-devel
[root@prd-airflow001 ~]$ yum -y install openssl openssl-devel
[root@prd-airflow001 ~]$ yum -y install openssl-static
[root@prd-airflow001 ~]$ yum -y install xz lzma xz-devel
[root@prd-airflow001 ~]$ yum -y install sqlite sqlite-devel
[root@prd-airflow001 ~]$ yum -y install gdbm gdbm-devel
[root@prd-airflow001 ~]$ yum -y install tk tk-devel
[root@prd-airflow001 ~]$ yum -y install db4-devel libpcap-devel libffi-devel
[root@prd-airflow001 ~]$ yum -y install epel-release
[root@prd-airflow001 ~]$ yum -y install gcc
二、下载安装包
#1.使用wget下载Python源码压缩包到/root目录下
[root@prd-airflow001 ~]$ cd /data/software
[root@prd-airflow001 /data/software]$ wget https://www.python.org/ftp/python/3.9.4/Python-3.9.4.tgz
#2.解压python3安装包
[root@prd-airflow001 /data/software]$ tar -zxvf Python-3.9.4.tgz -C /root
#3.进入安装目录
[root@prd-airflow001 /data/software]$ cd /root/Python-3.9.4/
#4.创建python3程序目录
[root@prd-airflow001 ~/Python-3.9.4]$ mkdir /usr/local/python3.9.4
三、生成Makefile文件
[root@prd-airflow001 ~/Python-3.9.4]$ mkdir bld
[root@prd-airflow001 ~/Python-3.9.4]$ cd bld/
[root@prd-airflow001 ~/Python-3.9.4/bld]$ ../configure --prefix=/usr/local/python3.9.4
四、编译安装
#1.编译安装
[root@prd-airflow001 ~/Python-3.9.4/bld]$ make && make install
#2.做软连接
[root@prd-airflow001 ~/Python-3.9.4/bld]$ cd /usr/local/
[root@prd-airflow001 /usr/local]$ ln -s python3.9.4 python3
五、配置环境变量
[root@prd-airflow001 ~/Python-3.9.4/bld]$ vim /etc/profile.d/python3.sh
export PATH=/usr/local/python3/bin:$PATH
[root@prd-airflow001 ~/Python-3.9.4/bld]$ source /etc/profile
六、查看python版本
#1.查看Python版本
[root@prd-airflow001 ~/Python-3.9.4/bld]$ python3 -V
Python 3.9.4
#2.检测pip是否可用
[root@prd-airflow001 ~/Python-3.9.4/bld]$ pip3 -V
pip 20.2.3 from /usr/local/python3/lib/python3.9/site-packages/pip (python 3.9)
#3.升级pip
[root@prd-airflow001 ~/Python-3.9.4/bld]$ pip3 install --upgrade pip
#4.再次查看pip版本
[root@prd-airflow001 ~/Python-3.9.4/bld]$ pip3 -V
pip 21.1.2 from /usr/local/python3/lib/python3.9/site-packages/pip (python 3.9)
