Installing Razor

Puppet Enterprise — 2017.3
Sections

After you set up a Razor environment, you're ready to install Razor.

Install Razor

At a minimum, to install Razor, you must install the Razor server. You may also install the client to make interacting the the server easier, and enable authentication security to control permissions.

Tip: Use variables to avoid repeatedly replacing placeholder text. For installation, we recommend declaring a server name and the port to use for Razor with these commands:
export RAZOR_HOSTNAME=<server name>
export HTTP_PORT=8150
export HTTPS_PORT=8151

The installation tasks on this page use $<RAZOR_HOSTNAME>, $<HTTP_PORT>, and $<HTTPS_PORT> to represent these variables.

Install the Razor server

Installing Razor involves classifying a node with the pe_razor module. 

When Puppet Enterprise applies this classification, the software downloads automatically and installs a Razor server and a PostgreSQL database. The download can take several minutes.

Because the Razor software is stored online, you need an internet connection to install it.

Important: Don't install the Razor server on your master.
  1. In the console, create a classification node group for the Razor server.
  2. Click the Razor server node group, click Configuration, then in the Add new class field, enter pe_razor and click Add class.
  3. Commit changes.
  4. On the Razor server, run Puppet: puppet agent -t

Install the Razor server while you're offline

Install Razor using your own remote directory containing a Puppet Enterprise tarball and the Razor microkernel.

Before you begin

Copy the Razor microkernel and the  Puppet Enterprise tarball appropriate for your installation to your own FTP site or to the Razor server.

If you save the files locally, when you specify directory paths, use three forward slashes (file:///). If you save the files on the Razor server, use two forward slashes (file://).

The example parameter values in this task use this directory structure: 
[root@razor ~]# tree  /tmp/razor_files/
/tmp/razor_files/
├── 2017.2.3/
│   └── puppet-enterprise-2017.2.3-el-7-x86_64.tar.gz
└── microkernel-008.tar
  1. In the console, create a classification node group for the Razor server.
  2. Click the Razor server node group, click Configuration, then in the Add new class field, enter pe_razor and click Add class.
  3. In the pe_razor class, specify the URL for your tarball, and then click Add parameter.
    ParameterValue
    pe_tarball_base_url
    Note: This parameter can be used only for installation, not upgrades

    Full path to a directory that contains <PE_VERSION>/<PE_INSTALLER>.tar.gz, for example file:///tmp/razor_files.

    The complete URL is automatically constructed by appending the PE build and file name to the base directory.

  4. In the pe_razor class, specify the URL for the microkernel, and then click Add parameter.
    ParameterValue
    microkernel_url

    Full path to the microkernel-<VERSION>.tar, for example file:///tmp/razor_files/microkernel-008.tar.

  5. Commit changes.
  6. On the Razor server, run Puppet: puppet agent -t
  7. (Optional) Install the Razor client.
    1. From a web-enabled machine, fetch these gems:
      /opt/puppetlabs/puppet/bin/gem fetch colored --version 1.2
/opt/puppetlabs/puppet/bin/gem fetch command_line_reporter --version 3.3.6
/opt/puppetlabs/puppet/bin/gem fetch mime-types --version 1.25.1
/opt/puppetlabs/puppet/bin/gem fetch multi_json --version 1.12.1
/opt/puppetlabs/puppet/bin/gem fetch razor-client --version 1.9.4
/opt/puppetlabs/puppet/bin/gem fetch faraday --version 0.15.4
    2. Copy the downloaded gems to a directory on the Razor server.
    3. Install the gems on the Razor server: /opt/puppetlabs/puppet/bin/gem install -f --local *.gem

Change the default Razor port

The default ports for Razor are port 8150 for HTTP communication between the server and nodes, and port 8151 for HTTPS, used for accessing the public API. You can optionally change the default ports if they’re occupied by another service, out of range, or blocked by a firewall.

  1. In the console, select the Classification, then click the node group that contains the pe_razor module.
  2. On the Configuration tab, under pe_razor in the Parameters box, select whether you want to change server_http_port or server_https_port.
  3. In the Value field, enter the port number to use, click Add parameter, and then commit changes.

Parameters for the pe_razor class

Parameters for the pe_razor class enable customization of your Razor installation. You can review configuration settings that are currently being used by Razor with the razor config command.

The pe_razor class has these parameters:
ParameterDefaultDescription
api_config_blacklist [‘facts.blacklist’, ‘database_url’]Properties that Razor hides from query results. You can add additional properties to protect sensitive data.
auth_config /etc/puppetlabs/razor-server/shiro.iniPath to the authentication configuration file.
auth_enabled false true to enable authentication for requests to /api endpoints, or false.
broker_path /etc/puppetlabs/razor-server/brokers:brokersColon-separated list of directories containing broker types.

task_path /etc/puppetlabs/razor-server/tasks:tasksColon-separated list of directories containing tasks.

Verify the Razor server

Use a test command to verify that the Razor server is correctly installed. The output JSON file test.out contains a list of available Razor commands.

Test the Razor configuration:  
wget https://$<RAZOR_HOSTNAME>:$<HTTPS_PORT>/api -O test.out

Install the Razor client

The Razor client is installed as a Ruby gem, pe-razor-client. The process for installing the client differs by platform.

Note: Don’t install the Puppet Enterprise Razor client, pe-razor-client, alongside the open source Razor client, razor-client. If you already have razor-client installed, or are not sure if you do, run gem uninstall razor-client before installing the Puppet Enterprise client.

Install the Razor client on *nix systems

Make interacting with the Razor server from *nix systems easier by installing the Razor client.

  1. Install the client: gem install pe-razor-client
    Tip: If you're installing the Razor client on your master, you must specify the location of the gem: /opt/puppetlabs/puppet/bin/gem install pe-razor-client
  2. Point the Razor client to the server: razor -u https://$<RAZOR_HOSTNAME>:$<HTTPS_PORT>/api

    An error displays if the client isn’t installed or can’t connect to the server.

  3. (Optional) If you receive a warning message about JSON, you can optionally disable it: gem install json_pure

Install the Razor client on Windows systems

Make interacting with the Razor server from Windows systems easier by installing the Razor client.

  1. From a Puppet command prompt ( Start > Start Command Prompt with Puppet > Run as administrator), install the client: gem install pe-razor-client
  2. Set an environment variable for the Razor server URL: setx RAZOR_API https://$<RAZOR_HOSTNAME>:8151/api.
    Tip: Alternatively, you can set the variable through User Accounts in the Control Panel.

Enable authentication security

Enable authentication security to control what tasks users can perform. For example, you might limit certain users to read permissions to avoid accidental overwrite of nodes.

Two methods are required to secure your Razor server:

  • Authentication security using Shiro – disabled by default

  • Protocol security using HTTPS and TLS/SSL – enabled by default if you’re using Puppet Enterprise and you install Razor on a managed node

  1. In the console, in the pe_razor class, specify Shiro authentication parameters.
    Parameter Value
    auth_enabled true
    auth_configured Location of the Shiro file, /etc/puppetlabs/razor-server/shiro.ini
  2. Specify users and roles in your shiro.ini file, located at /etc/puppetlabs/razor-server/shiro.ini.
    For example, this INI file specifies two users: razor is an admin who can perform all functions, and other is a user who can perform only read operations, such as viewing collections.
    [main]

[users]
# define users known to shiro, using the format:
# <username> = <password>, <role>[, <role>...]
razor = razor, admin
other = pass, user

[roles]
# define roles and their associated permissions
admin = *
user = query:*
  3. Restart the Razor service: service pe-razor-server restart

Permissions for Razor

These are the available permissions for Razor.

Note: Commands have varying access control patterns. Use razor <COMMAND_NAME> --help to view required permissions for each command.
TaskPermission
Query all collections query:*
Query the node collection query:nodes
Query a specific node query:nodes:<NODE_NAME>
Run all commands commands:*
Create policies commands:create-policy:*
Create policies starting with a specific name commands:create-policy:<NAME>*

Verify Razor versions

Verify your installation by checking the version of the Razor server and client. This information can also be useful for troubleshooting.

On the client or server, verify versions: razor --version or razor -v
