1.安装依赖包(CentOS可采用yum)
zypper in gcc gcc-c++ openssl-devel-32bit openssl-devel readline-devel readline-devel-32bit sqlite-devel tk tk-32bit tk-devel
2.下载Python源码包
cd /usr/src/
wget https://www.python.org/ftp/python/2.6.6/Python-2.6.6.tgz
3.编译安装
cd /usr/src/ tar zxvf Python-2.6.6.tgz cd Python-2.6.6 ./configure --prefix=/usr/local/python2.6.6 make make install
4.替换旧版本Python
查看旧版本Python命令路径
which python
这里为/usr/local/bin/python
进行版本替换
mv /usr/local/bin/python /usr/local/bin/python.bak ln -s /usr/local/python2.6.6/bin/python2.6 /usr/local/bin/python echo "export PATH=$PATH:/usr/local/python2.6.6/bin/" >> /etc/profile source /etc/profile
5.验证
执行“python”命令,无报错即证明安装完成
##############以上即完成python的升级###############
注:
1.升级python不要删除原有版本
2.执行make完成后提示如下fails:
Python build finished, but the necessary bits to build these modules were not found: _bsddb _sqlite3 _ssl _tkinter bsddb185 bz2 dbm gdbm readline sunaudiodev To find the necessary bits, look in setup.py in detect_modules() for the module‘s name.
处理方法:参见本文“1.安装依赖包(CentOS可采用yum)”

3.CentOS源码升级python方法基本同上,升级完成后yum将不可用,修复yum方法:
编辑/usr/bin/yum,修改#!/usr/bin/python为#!/usr/bin/python2.4(原版本)。
4.执行python命令,报错“import readline ImportError: No module named readline”处理方法:
安装readline-devel即可。
