centos6.5下安装python3.6、pip、ipython

1 cd /etc/yum.repos.d/
2 wget http://mirrors.163.com/.help/CentOS6-Base-163.repo #下载网易源
3 mv CentOS-Base.repo CentOS-Base.repo.ori #备份源
4 mv CentOS6-Base-163.repo CentOS-Base.repo #把网易源更改为默认源

1 yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel

 wget https://www.python.org/ftp/python/3.6.1/Python-3.6.1.tgz
 tar vxf Python-3.6.1.tgz
 cd Python-3.6.1.tgz ./configure --prefix=/usr/local #编译，自定义安装目录，如果自定目录不在环境变量重要，要把安装的目录加入到环境变量中 make && make install #这个过程会非常慢 
 ln –s /usr/local/bin/python3 /usr/bin/python3 #建立软连接

[root@centos6 bin]# python3
