MaxWiki Install

Here are detailed instruction on installing MaxWiki and its supporting environment on Linux. Even though the samples below are for RedHat, they should also work on most other Linux distributions with a little tweaking. For Windows and Mac, follow the alternate instructions for setting up Ruby/Gems/Rails then continue with the MySQL section.

Ruby

  1. Download and install Ruby 1.86

(From: RubyOnRails Download)

Gems

  1. Download RubyGems
  2. Extract then run: ruby setup.rb

(From: RubyOnRails Download)

Rails

  1. Run: gem install rails --include-dependencies

(From: RubyOnRails Download)

MySQL

  1. Install MySQL5
  2. Create database and user and assign rights:
    mysql -u root -p
      create database maxwiki;
      create database maxwiki_test;
      grant all on maxwiki.* to rails@localhost identified by 'password';
      grant all on maxwiki_test.* to rails@localhost;

Install MaxWiki

  1. Create and goto MaxWiki directory: /usr/local/rails/maxwiki
  2. Checkout from svn:
    svn checkout svn://rubyforge.org/var/svn/maxwiki/trunk     .
  3. For enterprise customers, get the additional plugins (username and password needed):
    cd /usr/local/rails/maxwiki/vendor/plugins
     svn checkout http://svn.maxwiki.com/svn/maxwiki_ent/plugins/maxwiki_multihost
    svn checkout http://svn.maxwiki.com/svn/maxwiki_ent/plugins/maxwiki_convert
    svn checkout http://svn.maxwiki.com/svn/maxwiki_ent/plugins/maxwiki_webdav
    svn checkout http://svn.maxwiki.com/svn/maxwiki_ent/plugins/maxwiki_webdav_auth
  4. Also for enterprise customers, get the files for your site (username and password needed):
    cd /usr/local/rails/maxwiki/public/files
    svn checkout http://svn.maxwiki.com/svn/maxwiki_ent/files/your_site_name

Rails User

  1. Create group: groupadd rails
  2. Create user:
    useradd -c “Rails Server” -g rails rails
    passwd rails
  3. Change owner of rails files: chown -R rails:rails /usr/local/rails

Setup MaxWiki

For the following files, copy the file to a new file without the .template extension, then customize. For instance, copy database.yml.template to database.yml.

  • config/database.yml
  • config/local_environment.rb

local_environment.rb

If you are running the Enterprise multi-host, change the top of this file to something like:

MY_CONFIG[:host_map] = [
   {:host => 'www.maxwiki.com', :name => 'maxwiki'},   
   {:host => 'maxwiki.com', :redirect_to => 'www.maxwiki.com'},   
]

Database Setup

  1. To setup the database tables run: rake db:migrate

Install Mongrel

  1. Install Mongrel: gem install mongrel mongrel_cluster --include-dependencies

Test

At this point, it is a good idea to test MaxWiki with Mongrel (and no Apache).

  1. Start Mongrel with: mongrel_rails start
  2. Access your server at port 3000. For instance, if installing locally use: http://localhost:3000
  3. Fill in the MaxWiki setup screen fields and save.

If you are setting up a development system, you can stop here. The following sections are for production servers.

Single Mongrel

For many installations, a singe mongrel instance under Apache will work fine (and is much easier to configure). Follow the instructions below, but change the RewriteRule line to:

  RewriteRule .* http://127.0.0.1:8000%{REQUEST_URI} [L,P,QSA]

And start Mongrel with:

  mongrel_rails start -d -p 8000 -e production -P /full/path/to/log/mongrel-1.pid

(From: Apache Best Practice Deployment)

Mongrel Cluster

For installations where it will be getting many simultaneous hits, setting up a mongrel cluster is required for best performance.

  1. In Rails home: /usr/local/rails/maxwiki
  2. Add file: conf/mongrel_cluster.yml
    ---
    cwd: /usr/local/rails/maxwiki
    port: "8000"
    environment: production
    address: 127.0.0.1
    pid_file: log/mongrel.pid
    servers: 3
    user: rails
    group: rails
  3. Add Mongrel as a system service:

    cd /etc/init.d
    sudo ln -s /usr/local/lib/ruby/gems/1.8/gems/mongrel_cluster-0.2.1/resources/mongrel_cluster mongrel_cluster
    sudo chmod +x mongrel_cluster
    sudo /sbin/chkconfig --level 345 mongrel_cluster on
    sudo mkdir /etc/mongrel_cluster
    sudo ln -s /usr/local/rails/maxwiki/config/mongrel_cluster.yml /etc/mongrel_cluster/maxwiki.yml

Apache mod_proxy

We need to add mod_proxy support to Apache 2.2 since the default doesn't include it.

  1. Download and expand Apache proxy module source:
    cd /usr/local/src
    wget http://apache.mirror.positive-internet.com/httpd/httpd-2.2.3.tar.gz
    tar –xzvf httpd-2.2.3.tar.gz
  2. Add proxy modules to apache:
    /usr/local/apache2/bin/apxs -i -a -c mod_proxy.c proxy_util.c
    /usr/local/apache2/bin/apxs -i -a -c mod_proxy_balancer.c
    /usr/local/apache2/bin/apxs -i -a -c mod_proxy_http.c

(From: Apache 2.2 + mod_proxy_balancer)

Apache Virtual Server

  1. Change to Apache directory: cd /usr/local/apache2
  2. At bottom of: conf/httpd.conf
    NameVirtualHost *:80
    NameVirtualHost *:443
    Include conf.d/*.conf 
  3. Create file: conf.d/1_maxwiki.conf
    <VirtualHost *:80>
      # This should remain the first virtual host because it will service all hosts
      # that are not explicitly defined in other VirtualHost sections
      # Also, we don't need to define any ServerName or ServerAlias
      DocumentRoot /usr/local/rails/maxwiki/public
      <Directory "/usr/local/rails/maxwiki/public">
        Options FollowSymLinks
        AllowOverride None
        Order allow,deny
        Allow from all
      </Directory>

      # this not only blocks access to .svn directories, but makes it appear
      # as though they aren't even there, not just that they are forbidden
      <DirectoryMatch "^/.*/\.svn/">
        ErrorDocument 403 /404.html
        Order allow,deny
        Deny from all
        Satisfy All
      </DirectoryMatch>

      # Rewrite to check for Rails cached page
      # Also for caching, take out :80 if present, and change : to _
      RewriteEngine On
      RewriteRule ^/$ /cache/%{HTTP_HOST}/index.html [QSA]  
      RewriteRule ^/([^.]+)$ /cache/%{HTTP_HOST}/$1.html [QSA]
      RewriteRule ^(.*):80(.*)$ $1$2 [QSA]
      RewriteRule ^(.*):(.*)$ $1_$2 [QSA]

      # Redirect all non-static requests to cluster
      RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} !-f
      RewriteRule ^(.*)$ balancer://mongrel_cluster_maxwiki%{REQUEST_URI} [P,QSA,L]
    </VirtualHost>

    <Proxy balancer://mongrel_cluster_maxwiki>
      BalancerMember http://127.0.0.1:8000
      BalancerMember http://127.0.0.1:8001
      BalancerMember http://127.0.0.1:8002
    </Proxy>
  4. Restart http:
    • Check syntax: bin/apachectl -t
    • Restart: bin/apachectl restart

Update Instructions

  1. Update the main MaxWiki files. In the MaxWiki Rails root directory: 
    svn update
  2. Update the site specific files (if you have Multi-Host). In /RAILS_ROOT/public/files/mysite directory:
    svn update
  3. Update the database: Back in the MaxWiki Rail root directory:
    rake db:migrate
  4. Restart Mongrel:
    mongrel_cluster_ctl restart
