CentOS 7下安装Python 3.7.0
1. 安装依赖环境
首先我们需要安装Python的依赖环境，不然在安装过程中容易报错
[root@docker-02 ~]# yum install gcc-c++
[root@docker-02 ~]# yum -y install -y lsb
[root@docker-02 ~]# yum -y install -y libXScrnSaver
[root@docker-02 ~]# 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 libffi-devel2.下载Python 3.7.0
在这里我们首先打开官网Python.org.在 Downloads目录下的Source code中进行查看Python的版本及其下载链接。这里我们选择3.7.0版本，翻着页面下方Files表单，选择Gzipped source tarball右键复制链接地址
[root@docker-02 ~]# wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz3.解压下载的包
[root@docker-02 ~]# tar -xvzf Python-3.7.0.tgz
[root@docker-02 ~]# cd Python-3.7.0/4.添加相关配置信息
[root@docker-02 Python-3.7.0]# ./configure --prefix=/usr/python3 --enable-optimizations --with-ssl5.编译和安装
[root@docker-02 Python-3.7.0]# make && make install6.创建软连接
[root@docker-02 Python-3.7.0]# ln -s /usr/python3/bin/python3 /usr/bin/python3
[root@docker-02 Python-3.7.0]# ln -s /usr/python3/bin/pip3 /usr/bin/pip37.pip升级
[root@docker-02 Python-3.7.0]# pip3 install --upgrade pip

现在就可以用python3命令进入Python3.7啦，也可以用pip3安装库了
[root@docker-02 Python-3.7.0]# python3 --version
