本文实例讲述了CentOS7环境搭建python3以及与python2实现共存的方法。分享给大家供大家参考,具体如下:
注意事项:
1、非root帐号加上sudo
2、centos7自带Python 2.7.5是不能卸载的,很多系统级软件依赖这个
安装依赖
# yum -y groupinstall "Development tools" # 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
下载python3,我的是Python-3.4.2.tgz
# wget https://www.python.org/ftp/python/3.4.2/Python-3.4.2.tgz # mkdir /usr/local/python3 # tar -zxvf Python-3.4.2.tgz # cd Python-3.4.2 # ./configure --prefix=/usr/local/python3 # make && make install # ln -s /usr/local/python3/bin/python3 /usr/bin/python3
测试
查看版本
# python3 Python 3.4.2 (default, Jul 19 2016, 03:47:32) [GCC 4.8.5 20150623 (Red Hat 4.8.5-4)] on linux Type "help", "copyright", "credits" or "license" for more information. >
代码测试
在当前目录新建个python脚本hello.py
内容:
#!/usr/bin/python3 # 第一个注释 print ("Hello, Python3!") 执行 # python3 hello.py Hello, Python3!
希望本文所述对大家CentOS服务器维护有所帮助。
