安装python3

安装环境：yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-develreadline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel sqlite-devel
下载安装包：wget https://www.python.org/ftp/python/3.6.1/Python-3.6.1.tgz
解压：tar -zxvf Python-3.6.1.tgz
cd Python-3.6.1
1.创建目录：mkdir -p /usr/local/python3
2.指定安装路径进行安装：./configure --prefix=/usr/local/python3
如果出现错误：configure: error: no acceptable C compiler found in $PATH
原因：缺少gcc编译环境
解决：yum install -y gcc
3.编译安装：make && make install
4.创建软链接：
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
