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。
