Python 编译安装/库安装Python 编译安装/缺少模块
好处
它不如yum等安装工具的安装，不会破坏原来系统的关联（通常不会）
它的安装只是将文件放置于恰当的位置
有趣
可重复编译
看起来你随便编译几次都随你
困扰
如何卸载源码安装呢？
可能卸载源码安装吗？

Centos5 编译安装Python2.7
获得python2.7.4
wget http://www.python.org/ftp/python/2.7.4/Python-2.7.4.tgz

解压
tar zxvf Python-2.7.4.tgz
进入目录咯 cd Python-2.7.4
[root@li84-236 app]# cd Python-2.7.4[root@li84-236 Python-2.7.4]# lsbuild configure Include Mac Modules pyconfig.h READMEconfig.guess configure.ac install-sh Makefile Objects pyconfig.h.in RISCOSconfig.log Demo Lib Makefile.pre Parser python setup.pyconfig.status Doc libpython2.7.a Makefile.pre.in PC Python Toolsconfig.sub Grammar LICENSE Misc PCbuild python-gdb.py
初始化编译配置啥子的
./configure
这玩意检查了一大串的东西
编译，以及安装
sudo make && make install
这里用&&看起来是make成功后再执行后面的
它很可能以这里结束

到这里编译安装就完成了

Linux下is not in the sudoers file解决方法
当我们使用sudo命令切换用户的时候可能会遇到提示以下错误：xxx is not in the sudoers file. This incident will be reported，xxx是你当前的用户名，究其原因是用户没有加入到sudo的配置文件里
vi/vim
切换到root用户，运行visudo命令
2
在打开的配置文件中，找到root ALL=(ALL) ALL，在下面添加一行
xxx ALL=(ALL) ALL 其中xxx是你要加入的用户名称
3
输入:wq保存并退出配置文件，再次使用sudo命令就不会有上面的提示了。
sudo:can't open /etc/sudoers: Permission denied 解决方法：chmod -R 0440 /etc/sudoers.d 或 chmod u-w /etc/sudoers
sudo lsattr /etc/sudoers
看有没有 i 属性
假如有 sudo chattr -i /etc/sudoers
