一、安装perl
[root&＃64;centos ~]# wget http://bcs.duapp.com/xiueli/perl-5.16.0.tar.gz
[root&＃64;centos ~]# tar zxvf perl-5.16.0.tar.gz
[root&＃64;centos ~]# cd perl-5.16.0
[root&＃64;centos perl-5.16.0]# mkdir -p /usr/local/perl
[root&＃64;centos perl-5.16.0]# ls /usr/local/
编译参数使用默认的
[root&＃64;centos perl-5.16.0]# ./Configure -des -Dprefix&＃61;/usr/local/perl/
[root&＃64;centos perl-5.16.0]# make
[root&＃64;centos perl-5.16.0]# make test
[root&＃64;centos perl-5.16.0]# make install
到此安装结束&＃xff0c;测试是否正常安装。
[root&＃64;centos ~]# perl -v

二、安装python、及问题解决
[root&＃64;centos ~]# wget http://bcs.duapp.com/xiueli/Python-2.7.3.tar.bz2
[root&＃64;centos ~]# tar jxvf Python-2.7.3.tar.bz2
[root&＃64;centos ~]# cd Python-2.7.3
[root&＃64;centos perl-5.16.0]# mkdir -p /usr/local/python
[root&＃64;centos perl-5.16.0]# ls /usr/local/
[root&＃64;centos Python-2.7.3]# ./configure --prefix&＃61;/usr/local/python/
[root&＃64;centos Python-2.7.3]# make
遇到问题&＃xff1a;
Python build finished, but the necessary bits to build these modules were not found:
_bsddb _sqlite3 _tkinter
bsddb185 bz2 dbm
gdbm readline sunaudiodev
To find the necessary bits, look in setup.py in detect_modules() for the module&＃39;s name.
Failed to build these modules:
_curses _curses_panel
由提示&＃xff0c;先解决未编译成功模块_curses、_curses_panel 这是由于相关的库文件找不到引起的&＃xff0c;安装ncurses可解决&＃xff0c;但ncurses是比较常见的&＃xff0c;此前应该安装过&＃xff0c;系统里不应该没有&＃xff0c;也不管了&＃xff0c;使用yum安装。
[root&＃64;centos Python-2.7.3]# yum install ncurses ncurses-devel
再次make
[root&＃64;centos Python-2.7.3]# make
提示&＃xff1a;
Python build finished, but the necessary bits to build these modules were not found:
_bsddb _sqlite3 _tkinter
bsddb185 bz2 dbm
gdbm readline sunaudiodev
To find the necessary bits, look in setup.py in detect_modules() for the module&＃39;s name.
由提示可以看出&＃xff0c;之前的模块正常编译&＃xff0c;但系统任提示缺少相关必须的位。这个问题困扰了我许久&＃xff0c;在网上搜索了大量的资料&＃xff0c;也没找到较好的解决办法&＃xff0c;自己尝试安装一些相关的库&＃xff0c;任然出现这个提示。但网上有些文档提到这个问题很常见&＃xff0c;可忽略。自己尝试多次后未果&＃xff0c;也只得忽略&＃xff0c;后来证明没问题&＃xff0c;但这也为我后来安装gitosis出错排错带来了麻烦。忽略之后直接安装。
ps&＃xff1a;一些必要的模块还是要安装的&＃xff0c;如果自己实在解决不了就大胆跳过&＃xff0c;以后遇到问题&＃xff0c;提示python某个必要的模块没安装再进行解决。
[root&＃64;centos Python-2.7.3]# make install
[root&＃64;centos Python-2.7.3]# python -V
Python 2.4.3
此时python版本任为2.4&＃xff0c;这是因为centos系统中的python版本默认是2.4。替代默认的版本&＃xff1a;
[root&＃64;centos bin]# mv /usr/bin/python /usr/bin/python2.4 //可能python2.4已经存在
[root&＃64;centos bin]# ln -s /usr/local/python/bin/python /usr/bin/python
[root&＃64;centos bin]# which python
/usr/bin/python
[root&＃64;centos bin]# python -V
Python 2.7.3
升级安装好以后yum会无法使用&＃xff0c;因为yum使用的是2.4版本&＃xff0c;此时运行yum会有如下提示
[root&＃64;centos bin]# yum update
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:
No module named yum
Please install a package which provides this module, or
verify that the module is installed correctly.
It&＃39;s possible that the above module doesn&＃39;t match the
current version of Python, which is:
2.7.3 (default, Aug 12 2012, 20:23:42)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-51)]
If you cannot solve this problem yourself, please go to
the yum faq at:
http://wiki.linux.duke.edu/YumFaq
修改yum的配置文件以便能够识别2.4版本下的python
[root&＃64;centos bin]# vi /usr/bin/yum
将 #!/usr/bin/python 修改为#!/usr/bin/python2.4
再次运行yum正常。
----------------------------------补充----------------------------------------------------------
之前因为/usr/bin/ 已经有python2.4 所以将原本的python重命名为python2.4.1。修改/usr/bin/yum 是也改#!/usr/bin/python2.4 运行yum正常&＃xff0c;但每次开机提示&＃xff1a;
Traceback (most recent call last):
File "/usr/lib/wicd/wicd-daemon.py", line 46, in
import dbus
ImportError: No module named dbus
后来修改/usr/bin/yum为#!/usr/bin/python2.4.1 开机正常&＃xff0c;无该提示。
所以如果/usr/bin/ 已经有python2.4 mv时建议不要覆盖&＃xff0c;但diff /usr/bin/python2.4 /usr/bin/python2.4.1无输出&＃xff0c;重新修改/usr/bin/yum为#!/usr/bin/python2.4开机仍提示错误&＃xff0c;再次留下疑问&＃xff01;
