CentOS7下python3.x的源码安装

一、安装过程

1、下载源码包

　下载地址：https://www.python.org/downloads/source/

　或：https://www.python.org/ftp/python/

2、解压安装包，以python 3.7.8为例

[root@localhost ~]# ll Python-3.7.8.tgz 
-rw-r--r-- 1 root root 23276116 Jul  3 16:40 Python-3.7.8.tgz
[root@localhost ~]# tar -zxvf Python-3.7.8.tgz

3、安装相关依赖包

[root@localhost ~]# 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

4、开始编译安装

[root@localhost ~]# cd Python-3.7.8/
[root@localhost Python-3.7.8]# ./configure --prefix=/usr/local/python3
[root@localhost Python-3.7.8]# make && make install

5、建立软链接

[root@localhost Python-3.7.8]# ln -s /usr/local/python3/bin/python3.7 /usr/bin/python3
[root@localhost Python-3.7.8]# ln -s /usr/local/python3/bin/pip3.7 /usr/bin/pip3

6、测试

[root@localhost Python-3.7.8]# python3
