安装python3.6可能使用相关软件
# yum groupinstall 'Development Tools' # yum install -y ncurses-libs zlib-devel mysql-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel
安装python3.6.5
python官网下载https://www.python.org
下载的安装包存放在/usr/local目录
# cd /usr/local # wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tar.xz
解压：
# tar -xf Python-3.6.5.tar.xz
解压后新建文件夹将Python-3.6.5放在/usr/local/python3下
进入该目录····························一定要进去的哈，不然安装会出错
# mkdir python3 # mv Python-3.6.5 python3 # cd python3/Python-3.6.5
执行如下代码安装
···························--prefix选项是配置安装的路径,执行后所有资源文件放在/usr/local/python3.6的路径中
# ./configure --prefix=/usr/local/python3 --enable-optimizations # make # make altinstall
创建软连接
# ln -s /usr/local/python3/bin/python3 /usr/bin/python3 # ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
最后测试版本
# python3 -V
# pip3 -V
