    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
        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
