    pvbouwel/tomcat — version 0.4.2 Feb 4th 2015

    The goal is to have a puppet module that is able to install tomcat in its basic form. So to remove the dependency from runit. Additionally we want to support multiple versions on 1 server, for this each tomcat instance will have its own full blown home directory. Also it would be nice to have the possibility to configure the ports so that multiple instance can run simultaneously. I'd like to build on this project of erwbgy because I like the idea of using the tarballs to create a setup.

    puppet-tomcat

    Puppet module to install Apache Tomcat

    The recommended usage is to place the configuration in hiera and just:

    include tomcat
    

    Example hiera config is included in the root of the repository.

    If you use the puppet filestore, don't forget to stage your tarballs. The default tomcat naming scheme is used for the filenames.

    tomcat parameters

    basedir: The base installation directory. Default: '/opt/tomcat' this directory will hold the extracted tarball.

    bind_address: The IP or hostname to bind listen ports to. Default: $fqdn

    check_port: The port that the instance must be listening on (bound to bind_address) for it to be considered up. Default: '8080'

    config: A hash of additional configuration variables that will be set when templates are processed.

    dependencies: A list of Runit service directories whose services must be up before the Tomcat service is started.

    cpu_affinity: Enable CPU affinity to be set to only run processes on specific CPU cores - for example '0,1' to only run processes on the first two cores.

    files: A hash of configuration files to install - see below

    filestore: The Puppet filestore location where the Tomcat tarball and Jolokia war file are downloaded from. Default: 'puppet:///files/tomcat'

    gclog_enabled: Whether or not Garbage Collector logging is enabled. Default: 'false'

    gclog_numfiles: The number of garbage collector log files to keep. Default: '5'

    gclog_filesize: The maximum size of a garbage collector log file before it is rotated. Default: '100M'

    group: The user''s primary group. Default: 'tomcat',

    java_home: The base directory of the JDK installation to be used. Default: '/usr/java/latest'

    java_opts: Additional java command-line options to pass to the startup script

    jolokia: Whether or not to install the jolokia war file and configure a separate service to run it. Default: false

    jolokia_address: The address that the jolokia HTTP service listens on. Default: 'localhost'

    jolokia_cron: Whether or not to install cron jobs to run the Jolokia JMX monitoring scripts every minute writing to local log files. Default: 'true'

    jolokia_port: The port that the jolokia HTTP service listens on. Default: '8190'

    jolokia_version: The version of the jolokia war file to download and install. Default: '1.1.1'

    localhost: The localhost address to bind listen ports to. Default: 'localhost'

    logdir: The base log directory. Default: '/var/logs/tomcat'

    min_mem: The minimum heap size allocated by the JVM. Default: 1024m

    max_mem: The maximum heap size allocated by the JVM. Default: 2048m

    mode: The permissions to create files with (eg. 0444).

    remove_docs: Whether or not to remove the Tomcat docs under webapps. Default: true

    remove_examples: Whether or not to remove the Tomcat examples under webapps. Default: true

    templates: A hash of templates. if an entry is placed for one of the templates, the passed template is used instead of the template supplied in modules. Each template in the templates directory can be replaced by creating an entry for the name.

    ulimit_nofile: The maximum number of open file descriptors the java process is allowed. Default is '$(ulimit -H -n)' which sets the value to the hard limit in /etc/security/limits.conf (or equivalent) for the user.

    version: The version of the product to install (eg. 7.0.37). Required.

    workspace: A temporary directory to unpack install tarballs into. Default: '/root/tomcat'

    tomcat::instance parameters

    title: The user the Tomcat instance runs as service_ensure: Can be either present (default) or "running". If it is present a service script is provisioned. If it is "running" then on each puppet run the service will be checked and if it is not running it will be started.

    Plus all of the parameters specified in 'tomcat parameters' above

    Config files

    Files or templates for each of the Tomcat instances can be delivered via Puppet. The former are delivered as-is while the latter are processed as ERB templates before being delivered.

    For example configuration could be delivered using for instances running as the tomcat1 and tomcat2 users with:

    tomcat::config:
      admin_user: 'admin'
      admin_pass: 'admin'
    
    tomcat::files:
      conf/tomcat-users.xml:
        source: 'puppet:///files/tomcat/dev/context.xml'
      
    tomcat:
      tomcat1:
        config:
          admin_pass: 'tinstaafl'
        templates:
          conf/tomcat-users.xml:
            template: '/etc/puppet/templates/tomcat/dev1/tomcat-users.xml.erb'
      tomcat2:
        config:
          admin_pass: 'timtowtdi'
        templates:
          conf/tomcat-users.xml:
            template: '/etc/puppet/templates/tomcat/dev2/tomcat-users.xml.erb'
    

    Values set at the tomcat level as set for all instances so both the tomcat1 and tomcat2 instance would get the same context.xml file. Each instance would get their own tomcat-users.xml file based on the template specified with instance variables (like basedir and logdir) and config variables (like admin_user and admin_pass above) substituted.

    For example:

    <user username="<%= @admin_user %>"
          password="<%= @admin_pass %>"
          roles="tomcat,manager-gui"/>
    

    All files and templates are relative to the product installation. For example if the product installation is '/opt/tomcat/apache-tomcat-7.0.37' then the full path to the 'tomcat-users.xml' file would be '/opt/tomcat/apache-tomcat-7.0.37/conf/tomcat-users.xml'.

    Note that the path specified by the 'template' parameter is on the Puppet master.

    Default templates

    There are default templates for conf/server.xml to listen on the specified bind_address and for conf/logging.properties to use the specified logdir. These defaults are only used if the template is not specified using the templates configuration.

    Product files

    By default the product tar file (eg. 'apache-tomcat-7.0.55.tar.gz') is expected to be found under a 'tomcat' directory of the 'files' file store. For example if /etc/puppet/fileserver.conf has:

    [files]
    path /var/lib/puppet/files
    

    then put the tar file in /var/lib/puppet/files/tomcat. Any files specified with the 'files' parameter can also be placed in this directory.

    This location can be changed by setting the 'filestore' parameter.

    Facts

    This module will create a fact called tomcat_instances that will report on the provided instances.
