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 my dreamhost account, 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 to Tommaso Lanza, who, has written a shell script to automate this installation, which now includes mercurial, he has also left a few notes in the comments. Use at your own risk!.

Python

I thought all I would need to do is compile Python and get virtualenv running, 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 on dreamhost:

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/opt to install and $HOME/tmp to compile in. Dreamhost recommends $HOME/run to install and $HOME/soft to 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 at LDFLAGS and CPPFLAGS, the others are pretty standard compile env variables.

Update: Thanks to Christian, who, in the comments, provided additional instructions to 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 and virtualenvwrapper along 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
    Using real prefix '/home/dawatts/opt/Python-2.6.4'
    New python executable in testenv/bin/python2.6
    Also creating executable in testenv/bin/python
    Installing setuptools............done.
    (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
