Downloading and Installing¶
The recommended way to download moin2 is to clone the moin2 Mercurial repository or its mirror. Open a terminal window or a command prompt, cd to the directory that will hold your project root directory and enter either one of the commands below:
hg clone http://hg.moinmo.in/moin/2.0 moin-2.0 OR hg clone http://bitbucket.org/thomaswaldmann/moin-2.0 moin-2.0
Now make sure your work directory is using the default branch:
hg up -C default
An alternative installation method is to download the bz2 archive from http://hg.moinmo.in/moin/2.0 and unpack it. Once unpacked, continue to follow the instructions below.
Before you can run moin, you need to install it:
Using your standard user account, run the following command from the project root directory. Replace <python> in the command below with the path to a python 2.7 executable. This is usually just “python”, but may be “python2.7”, “/opt/pypy/bin/pypy” or even <some-other-path-to-python>:
<python> quickinstall.py OR <python> quickinstall.py <path-to-venv>
The above will download all dependent packages to the PIP cache, install the packages in a virtual environment, and compile the translations (*.po files) to binary *.mo files. This process may take several minutes.
The default virtual environment directory name is:
where <PROJECT> is the name of the project root directory, and <PYTHON> is the name of your python interpreter. As noted above, the default name may be overridden.
Check the output of quickinstall.py to determine whether there were fatal errors. The output messages will normally state that stdout and stderr messages were written to a file, a few key success/failure messages will be extracted and written to the terminal window, and finally a message to type “m” to display a menu.
If there are failure messages, see the troubleshooting section below.
Typing ”./m” (or “m” on Windows) will display a menu similar to:
usage: "./m <target>" where <target> is: quickinstall update virtual environment with required packages docs create moin html documentation extras install OpenID, Pillow, pymongo, sqlalchemy, ldap, upload.py interwiki refresh contrib/interwiki/intermap.txt (hg version control) log <target> view detailed log generated by <target>, omit to see list new-wiki create empty wiki sample create wiki and load sample data restore * create wiki and restore wiki/backup.moin *option, specify file import <dir> import a moin 1.9 wiki/data instance from <dir> index delete and rebuild indexes run * run built-in wiki server *options (--port 8081) backup * roll 3 prior backups and create new backup *option, specify file dump-html * create a static HTML image of wiki *option, specify directory css run Stylus and lessc to update theme CSS files tests * run tests, output to pytest.txt *options (-v -k my_test) coding-std correct scripts that taint the repository with trailing spaces.. api update moin api docs (files are under hg version control) dist delete wiki data, then create distribution archive in dist/ del-all same as running the 4 del-* commands below del-orig delete all files matching *.orig del-pyc delete all files matching *.pyc del-rej delete all files matching *.rej del-wiki create a backup, then delete all wiki data
While most of the above menu choices may be executed now, new users should do:
m sample # in Windows ./m sample # in Unix
to create a wiki instance and load it with sample data. Next, run the built-in wiki server:
m run # in Windows ./m run # in Unix
As the server starts, about 20 log messages will be output to the terminal window. Point your browser to http://127.0.0.1:8080, the sample Home page will appear and more log messages will be output to the terminal window. Do a quick test by accessing some of the demo items and do a modify and save. If all goes well, your installation is complete. The built-in wiki server may be stopped by typing ctrl-C in the terminal window.
If you plan on contributing to the moin2 project, there are more instructions waiting for you under the Development topic.
If you plan on using this wiki as a production wiki, then before you begin adding or importing data and registering users review the configuration options. See the sections on configuration for details. Be sure to edit wikiconfig.py (or wikiconfig_editme.py) and change the settings for:
If you plan on just using moin2 as a desktop wiki (and maybe help by reporting bugs), then some logical menu choices are:
- m docs - to create docs, see User tab, Documentation (local)
- m extras - to install Pillow for manipulating images
- m del-wiki - get rid of the sample data
- m new-wiki or m import ... - no data or moin 1.9 data
- m backup - backup wiki data as needed or as scheduled
Warning: Backing up data at this point may provide a false sense of security because no migration tool has been developed to migrate data between moin2 versions. In its current alpha state, there may be code changes that impact the structure of the wiki data or indexes. Should this occur, you must start over with an empty wiki and somehow copy and paste the contents of all the old wiki items into the new wiki. While no such changes are planned, they have happened in the past and may happen in the future.
If you installed moin2 by cloning the Moin2 Mercurial repository, then you will likely want to install updates on a periodic basis. To determine if there are updates available, open a terminal window or command prompt, cd to your project root, and enter the command below:
If there are any updates, a brief description of each update will be displayed. To add the updates to your cloned repository, do:
hg pull -u
After pulling updates, it is best to also rerun the quickinstall process to install any changes or new releases to the dependant packages:
m quickinstall # in Windows ./m run # in Unix
Now and then, PyPi might be down or unreachable.
There are mirrors b.pypi.python.org, c.pypi.python.org, d.pypi.python.org you can use in such cases. You just need to tell pip to do so:
# put this into ~/.pip/pip.conf [global] index-url = http://c.pypi.python.org/simple
Bad Network Connection¶
If you have a poor or limited network connection, you may run into trouble with the commands issued by the quickinstall.py script. You may see tracebacks from pip, timeout errors, etc. within the output of the quickinstall script.
If this is the case, you may try rerunning the “python quickinstall.py” script multiple times. With each subsequent run, packages that are all ready cached (view the contents of pip-download-cache) will not be downloaded again. Hopefully, any temporary download errors will cease with multiple tries.
While ActiveState bundles pip and virtualenv in its distribution, there are two missing files. The result is the following error messages followed by a traceback:
Cannot find sdist setuptools-*.tar.gz Cannot find sdist pip-*.tar.gz
To install the missing files, do the following and then rerun “python quickinstall.py”:
\Python27\Scripts\pip.exe uninstall virtualenv \Python27\Scripts\easy_install virtualenv
