1)编译安装python2.7
[root@mysql-master ~]# python -V Python 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 [root@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]# ls debug 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 -V Python 2.7.9 [root@mysql-master Python-2.7.9]# mv /usr/bin/python /usr/bin/python2.6 mv: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 -V Python 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/python2.6 import sys try: import yum except ImportError: print >> sys.stderr, """\ There was a problem importing one of the Python modules required to run yum. The error leading to this problem was: %s [root@mysql-master Python-2.7.9]# python Python 2.7.9 (default, Nov 16 2016, 19:53:47) [GCC 4.4.7 20120313 (Red Hat 4.4.7-16)] on linux2 Type "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。
