CENTOS安装Python3.7.2
1、在CentOS中下载最新的Python版本，我这里下载的是3.7.2版本。
wget https://www.python.org/ftp/python/3.7.2/Python-3.7.2.tgz
[root@VM_0_15_centos software]# wget https://www.python.org/ftp/python/3.7.2/Python-3.7.2.tgz

tar -zxvf Python-3.7.2.tgz
[root@VM_0_15_centos software]# tar -zxvf Python-3.7.2.tgz
3、删除旧版本的python依赖
ll /usr/bin |grep python
rm -rf /usr/bin/python
[root@VM_0_15_centos software]# ll /usr/bin |grep python
-rwxr-xr-x. 1 root root 11232 Aug 10 2017 abrt-action-analyze-python
lrwxrwxrwx. 1 root root 7 Jan 9 2018 python -> python2
lrwxrwxrwx. 1 root root 9 Jan 9 2018 python2 -> python2.7
-rwxr-xr-x. 1 root root 7136 Aug 4 2017 python2.7
[root@VM_0_15_centos software]# rm -rf /usr/bin/python4、 进入python目录并配置、编译
cd /usr/local/Python-3.7.2/^C
./configure
[root@VM_0_15_centos Python-3.7.2]# cd /usr/local/Python-3.7.2/^C
[root@VM_0_15_centos Python-3.7.2]# ./configure编译：make
[root@VM_0_15_centos Python-3.7.2]# make编译安装：make install
[root@VM_0_15_centos Python-3.7.2]# make install5、删除旧的软链接，创建新的。
rm -rf /usr/local/pthon3
ln -s /usr/local/bin/python3.7 /usr/bin/python
python -v
[root@VM_0_15_centos Python-3.7.2]# rm -rf /usr/local/pthon3[root@VM_0_15_centos bin]# rm -rf /usr/bin/python
[root@VM_0_15_centos bin]# ln -s /usr/local/bin/python3.7 /usr/bin/python
[root@VM_0_15_centos bin]# python -V
Python 3.7.2
