1）编译安装python2.7
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 | [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
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | 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。 |
