RHEL6.4上升级python从2.6.6到2.7.3

原始安装好的redhat6.4上的python版本是2.6.6,不能满足实际需要。升级的方法很多,从源码升级或者从rpm包升级。其中从rpm包升级相对简单。这里记录全部过程如下。准备新安装的RHEL6.4,没有安装任何其他多余的软件,配置好ISO作为本地YUM源。看看升级过程如下:

1 升级python

1) 首先是下载python的RPM包

rhel6使用下面的下载地址:

wget -c --no-check-certificate http://li.nux.ro/download/nux/dextop/el6/x86_64/python27-libs-2.7.3-6.2.el6.nux.x86_64.rpm
wget -c --no-check-certificate http://li.nux.ro/download/nux/dextop/el6/x86_64/python27-2.7.3-6.2.el6.nux.x86_64.rpm
wget -c --no-check-certificate http://li.nux.ro/download/nux/dextop/el6/x86_64/tkinter27-2.7.3-6.2.el6.nux.x86_64.rpm
wget -c --no-check-certificate http://li.nux.ro/download/nux/dextop/el6/x86_64/python27-devel-2.7.3-6.2.el6.nux.x86_64.rpm

rhel5 使用下面的下载地址:

wget -c --no-check-certificate ftp://ftp.pbone.net/mirror/dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/
  -- expat2-2.0.1-1.ius.el5.x86_64.rpm  
  -- python27-2.7.3-19.ius.el5.x86_64.rpm
  -- python27-libs-2.7.3-19.ius.el5.x86_64.rpm
  -- tkinter27-2.7.3-19.ius.el5.x86_64.rpm
  -- python27-devel-2.7.3-19.ius.el5.x86_64.rpm

2)然后以下面的次序安装

# rpm -ivh python27-libs-2.7.3-6.2.el6.nux.x86_64.rpm
# rpm -ivh python27-2.7.3-6.2.el6.nux.x86_64.rpm
# yum install tix
# rpm -ivh tkinter27-2.7.3-6.2.el6.nux.x86_64.rpm
# rpm -ivh python27-devel-2.7.3-6.2.el6.nux.x86_64.rpm

3) 测试是否组件可用

# python2.7 -c "import zlib, sqlite3 ssl"

2 安装python-inotify

这个是对文件目录变化实时监控的组件。python-inotify 依赖 pathlib。

$ wget --no-check-certificate https://pypi.python.org/packages/source/p/pathlib/pathlib-1.0.1.tar.gz
$ wget --no-check-certificate https://bitbucket.org/JanKanis/python-inotify/get/2193c8bdeb3b.zip

1) python-inotify需要安装gcc-c++

# yum install gcc-c++

2) 然后进入pathlib目录,执行:

# python2.7 setup.py build
# python2.7 setup.py install

3) 和JanKanis-python-inotify-2193c8bdeb3b目录

需要把./inotify/_inotify.c的开头添加下面的代码:

/* _inotify.c */
...
/* Exclude events on unlinked objects. */
#ifndef IN_EXCL_UNLINK
#  define IN_EXCL_UNLINK  0x04000000
#endif

然后执行:

# python2.7 setup.py build
# python2.7 setup.py install

4) 测试python-inotify

# python2.7 examples/simple.py

在/tmp下面写个文件看看!

如果升级之后, yum不可用,可以rpm安装python2.6.6, 参考:
