1）编译安装python2.7
[root@mysql-master ~]# python -VPython 2.6.6查看python的版本信息（之前的yum是通过yum安装的）[root@mysql-master src]# wget https://www.python.org/ftp/python/2.7.9/Python-2.7.9.tar.xz[roo<strong style="color:transparent">本文来源gao@daima#com搞(%代@#码@网&</strong>t@mysql-master src]# file Python-2.7.9.tar.xz Python-2.7.9.tar.xz: xz compressed data[root@mysql-master src]# xz -d Python-2.7.9.tar.xz [root@mysql-master src]# lsdebug kernels Python-2.7.9.tar[root@mysql-master src]# tar -xf Python-2.7.9.tar [root@mysql-master src]# cd Python-2.7.9[root@mysql-master Python-2.7.9]# ./configure [root@mysql-master Python-2.7.9]# make && make install[root@mysql-master Python-2.7.9]# echo $?0[root@mysql-master Python-2.7.9]# /usr/local/bin/python2.7 -VPython 2.7.9[root@mysql-master Python-2.7.9]# mv /usr/bin/python /usr/bin/python2.6mv：是否覆盖"/usr/bin/python2.6"？ yes[root@mysql-master Python-2.7.9]# ln -s /usr/local/bin/python2.7 /usr/bin/python[root@mysql-master Python-2.7.9]# python -VPython 2.7.9
2）调整yum的配置
因为yum使用会调用python的信息，避免重新安装python后，yum出现报错，编辑yum的文件：[root@mysql-master Python-2.7.9]# sed -i 's@#!/usr/bin/python@#!/usr/bin/python2.6@g' /usr/bin/yum[root@mysql-master Python-2.7.9]# cat /usr/bin/yum |head#!/usr/bin/python2.6import systry: import yumexcept ImportError: print >> sys.stderr, """\There was a problem importing one of the Python modulesrequired to run yum. The error leading to this problem was: %s[root@mysql-master Python-2.7.9]# pythonPython 2.7.9 (default, Nov 16 2016, 19:53:47) [GCC 4.4.7 20120313 (Red Hat 4.4.7-16)] on linux2Type "help", "copyright", "credits" or "license" for more information.>>> print "hello,world"hello,world到此，python2.7的基本安装也完成了。
