CentOS安装python3
系统环境:centos 7.6
Python 版本:Python-3.6.8
1. 环境依赖
Python3.x 的安装需要依赖这四个组件:gcc, zlib,zlib-devel,openssl-devel;所以需要预先安装,命令如下:
yum -y install gcc zlib zlib-devel openssl-devel
2. 下载编译
Python 官方下载地址: https://www.python.org/downloads/
Python 加速地址:https://repo.huaweicloud.com/python/
wget https://www.python.org/ftp/python/3.6.8/Python-3.6.8.tgz (官方下载地址)
wget https://repo.huaweicloud.com/python/3.6.8/Python-3.6.8.tgz (华为镜像站)
3. 解压编译
tar -zxvf Python-3.6.8.tgz
进入根目录进行编译,可以指定编译安装的路径,这里我们指定为 /usr/local/python3.6 :
cd Python-3.6.8 ./configure --prefix=/usr/local/python3.6
make && make install
4. 环境变量配置
vim /etc/profile export PYTHON_HOME=/usr/local/python3.6 export PATH=${PYTHON_HOME}/bin:$PATH
使得配置的环境变量立即生效:
source /etc/profile
也可以创建软链接
ln -s /usr/local/python3.6/bin/python3 /usr/bin/python3 ln -s /usr/local/python3.6/bin/pip3 /usr/bin/pip3
5. 验证安装是否成功
输入 python3 命令,如果能进入 python 交互环境,则代表安装成功:
[root@localhost ~]# python3 Python 3.6.8 (default, Mar 29 2019, 10:17:41) [GCC 4.8.5 20150623 (Red Hat 4.8.5-36)] on linux Type "help", "copyright", "credits" or "license" for more information. >>> 1+1 2 >>> exit() [root@localhost ~]#
