centos python 2.7 安裝

 一開始有這個需求，是由於用 YaH3C 替代 iNode 進行校園網認證時，一直編譯錯誤，提示找不到 Python 的某個模塊，百度了一下，此模塊是在 Python2.7 以上纔有的，可是系統的自帶的Python是2.6版本，難怪一直連不上網。因而，繼續百度google，進行安裝，後來又出現問題...在此開篇記錄一下，權當備忘。

 

python2.7安裝

探測機操做 升級python2.6到2.7  複製粘貼執行

cd /home/work/prober/src/lib/thirdparty
yum install xz unzip libcurl-devel zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make -y
wget https://www.python.org/ftp/python/2.7.9/Python-2.7.9.tar.xz
tar xf Python-2.7.9.tar.xz
cd Python-2.7.9
./configure 
make all
make install
make clean  
make distclean 
/usr/local/bin/python2.7 -V  
mv /usr/bin/python /usr/bin/python2.6.6
ln -s /usr/local/bin/python2.7 /usr/bin/python
cd ..


修改yum

vi /usr/bin/yum
將文件頭部的
#!/usr/bin/python
改爲
#!/usr/bin/python2.6.6



安裝setuptool pip  複製粘貼執行

https://pypi.python.org/pypi/setuptools頁面最下面的有它的安裝連接

cd /home/work/prober/src/lib/thirdparty
wget --no-check-certificate https://pypi.python.org/packages/source/s/setuptools/setuptools-12.0.3.tar.gz#md5=f07e4b0f4c1c9368fcd980d888b29a65

tar -xzf pip-8.1.1.tar.gz

python setup.py install

# 升級pip
python -m pip install --upgrade pip

#python  -V
Python 2.6.6

1.下載Python-2.7.3

 

 

#wget http://python.org/ftp/python/2.7.3/Python-2.7.3.tar.bz2

2.解壓

 

 

#tar -jxvf Python-2.7.3.tar.bz2

3.更改工做目錄

 

 

#cd Python-2.7.3

4.安裝

 

 

#./configure
#make all
#make install
#make clean
#make distclean

5.查看版本信息

 

 

#/usr/local/bin/python2.7 -V

6.創建軟鏈接，使系統默認的 python指向 python2.7

#mv /usr/bin/python /usr/bin/python2.6.6
#ln -s /usr/local/bin/python2.7 /usr/bin/python

7.從新檢驗Python 版本

 

 

#python -V

8解決系統 Python 軟連接指向 Python2.7 版本後，由於yum是不兼容 Python 2.7的，因此yum不能正常工做，咱們須要指定 yum 的Python版本

 

 

#vi /usr/bin/yum

 

 

將文件頭部的
#!/usr/bin/python

改爲
#!/usr/bin/python2.6.6

這篇教程就到這裏了，可是不久就忽然發現輸入法圖標不見了，而後打字沒有候選框！iBus 崩了！再次進行搜索，又是版本問題 iBus也是不支持Python2.7的啊！

因而。。。

 

9.配置iBus

分別用 vi 打開下面兩個文件，找到 exec python 那一行，把exec python 改成 exec python2.6 保存，退出。iBus在重啓後就恢復正常了！是否是很開心？

 

#vi /usr/bin/ibus-setup

#vi/usr/libexec/ibus-ui-gtk
