CentOS7安装Python3.6.5

一、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

二、安装python3.6.5

# 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

# cd Python-3.6.5

三、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

四、修改软链接：

# ln -s /usr/local/python3/bin/python3  /usr/bin/python3

# ln -s /usr/local/python3/bin/pip3  /usr/bin/pip3

最后查看安装版本：

# python3 -V

# pip3 -V
