执行两次

会自动根据本机的py版本选择对应的egg

安装时提示找不到zlib

安装zlib

yast -i zlib

wget ftp://mirror.switch.ch/pool/1/mirror/scientificlinux/5rolling/x86_64/SL/zlib-devel-1.2.3-3.x86_64.rpm

yast -i zlib-devel-1.2.3-3.x86_64.rpm

再重新python ez_setup.py

设置环境变量

vim /etc/profile

export PATH=/usr/local/python262/bin:$PATH

source /etc/profile

安装完可以看到有/usr/bin/easy_install程序了

easy_install MySQL-python

import MySQLdb

报错：

ImportError: libmysqlclient_r.so.16: cannot open shared object file: No such file or directory

1.确定libmysqlclient_r.so.16的位置

/usr/local/mysql/lib/mysql/libmysqlclient_r.so.16 -> libmysqlclient_r.so.16.0.0

2.确定libmysqlclient_r.so.16使用的函数库及其位置

ldd /usr/local/mysql/lib/mysql/libmysqlclient_r.so.16

/usr/local/mysql/lib/mysql/libmysqlclient_r.so.16.0.0

ldd -v /usr/local/mysql/lib/mysql/libmysqlclient_r.so.16

/lib64

3.拷贝函数库到需要位置

cp -af /usr/local/mysql/lib/mysql/libmysqlclient_r.so.16.0.0 /lib64 或者 vim /etc/ld.so.conf将/usr/local/mysql/lib/mysql该目录添加到第一行

4.ldconfig

5.ldconfig -v | grep libmysqlclient_r.so.16

import MySQLdb sucess!!!!

#######miss module

Late last year, I set out to get some python apps running on mydreamhostaccount, previously I maintained this stuff on an ec2 ubuntu instance, so I could do whatever I wanted there. But ec2 is expensive and dreamhost is cheap, so I made the move.

Update May 15, 2010: Thanks toTommaso Lanza, who, has written ashell scriptto automate this installation, which now includes mercurial, he has also left afew notes in the comments. Use at your own risk!.

Python

I thought all I would need to do is compile Python and getvirtualenvrunning, but there was a little more to it, because as soon as I compiled Python I received the following warning:

    Failed to find the necessary bits to build these modules:
_bsddb             _tkinter           bsddb185
bz2                readline           sunaudiodev
To find the necessary bits, look in setup.py in detect_modules() for the
module's name.

This doesn’t mean it didn’t compile, but it means those modules were not compiled in. I really wanted readline, and thought it would be a good idea to have bz2. I didn’t expect I’d need _tkinter, but who knows and I wasn’t sure when and where I might need berkeley db (_bsddb, note: you’ll need a 4.5 version of Berkeley DB if you want support). So I set out to compile these modules in. I wasn’t worried about needing sunaudiodev or bsddb185, they’re both very old.

Without documenting my errors along the way, here is how I installed Python 2.6.4 ondreamhost:

First give yourself a place to install the necessary packages, and then a place to compile them. You can name them whatever you want, I used$HOME/optto install and$HOME/tmpto compile in.Dreamhost recommends$HOME/runto install and$HOME/softto compile in. Do whatever your comfortable with.

    $ cd ~
$ mkdir opt tmp

Grab everything you’ll need and put that in tmp:

    $ cd tmp
$ wget http://www.bzip.org/1.0.5/bzip2-1.0.5.tar.gz
$ tar -xzf bzip2-1.0.5.tar.gz
$ wget ftp://ftp.gnu.org/gnu/readline/readline-5.2.tar.gz
$ tar -xzf readline-5.2.tar.gz
$ wget http://prdownloads.sourceforge.net/tcl/tcl8.5.8-src.tar.gz
$ tar -xzf tcl8.5.8-src.tar.gz
$ wget http://prdownloads.sourceforge.net/tcl/tk8.5.8-src.tar.gz
$ tar -xzf tk8.5.8-src.tar.gz
$ wget http://python.org/ftp/python/2.6.4/Python-2.6.4.tgz
$ tar -xzf Python-2.6.4.tgz
$ wget http://download.oracle.com/berkeley-db/db-4.5.20.tar.gz
$ tar -xzf db-4.5.20.tar.gz

Setup your environment:

    $ export LD_LIBRARY_PATH=$HOME/opt/local/lib:$HOME/opt/local/BerkeleyDB.4.5/lib
$ export LD_RUN_PATH=$LD_LIBRARY_PATH
$ export LDFLAGS="-L$HOME/opt/local/lib -L$HOME/opt/local/BerkeleyDB.4.5/lib"
$ export CPPFLAGS="-I$HOME/opt/local/include -I$HOME/opt/local/BerkeleyDB.4.5/include"
$ export CXXFLAGS=$CPPFLAGS
$ export CFLAGS=$CPPFLAGS

Setting all these environment variables may not be necessary it’s what I had at the end of compiling, Python looks atLDFLAGSandCPPFLAGS, the others are pretty standard compile env variables.

Update: Thanks toChristian, who,in the comments, provided additional instructionsto grab and install SSL support, if you think you’ll need SSL, here are the steps:

    $ wget http://www.openssl.org/source/openssl-0.9.8m.tar.gz
$ tar -xzf openssl-0.9.8m.tar.gz
$ cd openssl-0.9.8m
$ ./config --prefix=$HOME/opt/local --openssldir=$HOME/opt/local/openssl shared
$ make
$ make install
$ cd ..

Compile and Install

    $ cd readline-5.2
$ ./configure --prefix=$HOME/opt/local
$ make
$ make install
$ cd ..

$ cd tcl8.5.8/unix
$ ./configure --prefix=$HOME/opt/local
$ make
$ make install
$ cd ../..

$ cd tk8.5.8/unix
$ ./configure --prefix=$HOME/opt/local
$ make
$ make install
$ cd ../..

$ cd db-4.5.20/build_unix
$ ../dist/configure \
> --prefix=$HOME/opt/local/BerkeleyDB.4.5 \
> --enable-tcl \
> --with-tcl=$HOME/opt/local/lib
$ make
$ make install
$ cd ../..

$ cd bzip2-1.0.5
$ make
$ make install PREFIX=$HOME/opt/local
$ cd ..

$ cd Python-2.6.4
$ ./configure --prefix=$HOME/opt/Python-2.6.4
$ make
$ make install

When you ran make on Python-2.6.4, the only warning should now be:

    Failed to find the necessary bits to build these modules:
bsddb185           sunaudiodev
To find the necessary bits, look in setup.py in detect_modules() for the
module's name.

As I mentioned above, I don’t think I’ll ever need these 2 modules, if i ever do, I’ll worry about it then.

Next I updated my PATH to include the new binaries

    $ cd ~
$ vi ~/.bashrc

export PATH="$HOME/opt/local/bin:$PATH"

$ source ~/.bashrc

virtualenv and virtualenvwrapper

And finally I installed virtualenv andvirtualenvwrapperalong with some things in my .bashrc to make life easier.

    $ cd ~/tmp
$ wget http://pypi.python.org/packages/source/v/virtualenv/virtualenv-1.4.3.tar.gz
$ tar -xzf virtualenv-1.4.3.tar.gz
$ ~/opt/Python-2.6.4/bin/python2.6 virtualenv-1.4.3/virtualenv.py $HOME/opt/local
New python executable in /home/dawatts/opt/local/bin/python2.6
Also creating executable in /home/dawatts/opt/local/bin/python
Installing setuptools............done.
$ easy_install virtualenv
$ cd ..

$ wget http://www.doughellmann.com/downloads/virtualenvwrapper-1.23.tar.gz
$ tar -xzf virtualenvwrapper-1.23.tar.gz
$ mkdir $HOME/bin
$ cp virtualenvwrapper-1.23/virtualenvwrapper_bashrc ~/bin/

$ cd ~
$ mdkir $HOME/.virtualenvs
$ vi ~/.bashrc

export WORKON_HOME=$HOME/.virtualenvs
source $HOME/bin/virtualenvwrapper_bashrc

$ source ~/.bashrc
$ workon
*
$ mkvirtualenv testenv

New python executable in testenv/bin/python2.6
Also creating executable in testenv/bin/python

(testenv)$ workon
testenv
(testenv)$ deactivate
$ rmvirtualenv testenv

And there you have it, a Python 2.6.4/virtualenv environment setup on dreamhost to do whatever you wa
