部署一個程序，
系統環境：CentOS 6.10 64位
Python版本：2.7
1.升級下系統
yum install eple-release -y
yum update -y
2.下載python 2.7，編譯安裝
wget https://www.python.org/ftp/python/2.7.16/Python-2.7.16.tar.xz
tar xvf Python-2.7.16.tar.xz
cd Python-2.7.16
./configure
make && make install
3.修改默認python
mv /usr/bin/python /usr/bin/python.bak
ln -s /usr/local/bin/python /usr/bin/python
ln -s /usr/local/bin/python2.7 /usr/bin/python2.7
ln -s /usr/local/bin/python-config /usr/bin/python-config
到這一步已經基本安裝完畢，但還存在一些小問題需要調整
4.默認的yum 是python2.6，需要修改下，不然沒辦法使用。
vim /usr/bin/yum
將 #!/usr/bin/python 修改為 #!/usr/bin/python2.6
5.將Python2.6 的module文件拷貝到Python2.7中（不然在安裝一些程序時，會提示一些module缺失，還是要拷貝）
cp -r /usr/lib/python2.6/site-packages/yum /usr/local/lib/python2.7/site-packages/
cp -r /usr/lib/python2.6/site-packages/rpmUtils /usr/local/lib/python2.7/site-packages/
cp -r /usr/lib/python2.6/site-packages/iniparse /usr/local/lib/python2.7/site-packages/
cp -r /usr/lib/python2.6/site-packages/urlgrabber /usr/local/lib/python2.7/site-packages/
cp -r /usr/lib64/python2.6/site-packages/rpm /usr/local/lib/python2.7/site-packages/
cp -r /usr/lib64/python2.6/site-packages/curl /usr/local/lib/python2.7/site-packages/
cp -p /usr/lib64/python2.6/site-packages/pycurl.so /usr/local/lib/python2.7/site-packages/
cp -p /usr/lib64/python2.6/site-packages/_sqlitecache.so /usr/local/lib/python2.7/site-packages/
cp -p /usr/lib64/python2.6/site-packages/sqlitecachec.py /usr/local/lib/python2.7/site-packages/
cp -p /usr/lib64/python2.6/site-packages/sqlitecachec.pyc /usr/local/lib/python2.7/site-packages/
cp -p /usr/lib64/python2.6/site-packages/sqlitecachec.pyo /usr/local/lib/python2.7/site-packages/
