Centos 6.6自带的是Python 2.6.6, 现在升级为2.7.6
[root@office-vps4052 ~]# python -V
Python 2.6.6
操作步骤如下:
1) 下载并解压python 2.7.6源码包
[root@office-vps4052 ~]# cd /usr/local/src
[root@office-vps4052 ~]# wget http://python.org/ftp/python/2.7.6/Python-2.7.6.tgz
[root@office-vps4052 src]# tar -zxvf Python-2.7.6.tgz
[root@office-vps4052 src]# cd Python-2.7.6
[root@office-vps4049 Python-2.7.6]# ./configure –prefix=/usr/local/python27
[root@office-vps4049 Python-2.7.6]# make
[root@office-vps4049 Python-2.7.6]# make install
2) 备份/usr/bin/python
[root@office-vps4049 Python-2.7.6]# mv /usr/bin/python /usr/bin/python_old
3) 将新版Python 2.7.6软链到/usr/bin
[root@office-vps4049 Python-2.7.6]# ln -s /usr/local/python27/bin/python /usr/bin/python
4) 检查现有Python版本
[root@office-vps4049 Python-2.7.6]# python -V
Python 2.7.6
5) 修改/usr/bin/yum, 否则yum将无法使用
[root@office-vps4049 Python-2.7.6]# vim /usr/bin/yum
#!/usr/bin/python 修改为 #!/usr/bin/python2.6
6) 修改完/usr/bin/yum进行验证
[root@office-vps4049 Python-2.7.6]# yum -y install vim
