The solution：Recompile python

1. Extract the source file

    [root@arno Python-2.7.13]# tar xzf Python-2.7.13.tgz
    [root@arno Python-2.7.13]# cd Python-2.7.13

2. Check the tk/tcl version，Step 4 need the version information

    [root@arno Python-2.7.13]# rpm -qa | grep ^tk
    tk-8.5.7-5.el6.x86_64
    tkinter-2.6.6-66.el6_8.x86_64
    [root@arno Python-2.7.13]# rpm -qa | grep ^tcl
    tcl-8.5.7-6.el6.x86_64

3. Install tk/tcl devel

    [root@arno Python-2.7.13]# yum install tk-devel tcl-devel -y

4. Find these lines and cancel the comment

    [root@arno Python-2.7.13]# vim Modules/Setup
    # *** Always uncomment this (leave the leading underscore in!):
    _tkinter _tkinter.c tkappinit.c -DWITH_APPINIT \
    -L/usr/local/lib \
    -I/usr/local/include \
    -ltk8.5 -ltcl8.5 \           # this version is query at step 2.
    -lX11

5. Start complie & install python

    [root@arno Python-2.7.13]# ldconfig
    [root@arno Python-2.7.13]# ./configure --prefix=/opt/soft/python2 --with-ensurepip=install
    [root@arno Python-2.7.13]# make
    [root@arno Python-2.7.13]# make install

6. Config sys env.

   [root@arno Python-2.7.13]# mv /usr/bin/python /usr/bin/pythonbak
   [root@arno Python-2.7.13]# unlink /usr/bin/python2
   [root@arno Python-2.7.13]# vim /usr/bin/yum
    #!/usr/bin/python2.6
   [root@arno Python-2.7.13]# vim ~/.bash_profile
    # User specific environment and startup programs
    PYPATH=/opt/soft/python2/bin
    PATH=$PATH:$HOME/bin:$PYPATH
    export PATH
   [root@arno Python-2.7.13]# source ~/.bash_profile
