  • Description: 
    This ServerTemplate is on the LTS Lineage. For the latest Infinity version, see the Infinity Lineage  

For a description of the Infinity and LTS lineages, see ServerTemplate Release Methodology

This ServerTemplate configures a Rails application server with the Apache HTTP Server running Phusion Passenger. It is designed to work in a hybrid cloud setting, and with a CLB, ELB, or Load Balancer ServerTemplate and Database ServerTemplate as part of a three-tier web architecture. It also includes iptables management for clouds that do not have firewall services. 

Key Features:
* Firewall management within a three-tier scalable web architecture
* Utilizes RightScale tag-based routing for connecting to load balancers
* Pulls application code from an external repository (Git, SVN, or cloud storage)

Account name

The account name (i.e. username, ID) that is required to access files in the specified location. This input is optional and may not be required. Example: cred:RACKSPACE_USERNAME

Action

Specify how the application code will be pulled from the specified repository. 'pull'- standard repository pull, 'capistrano_pull' standard repository pull plus a capistrano deployment style is applied. Example: pull

AllowOverride Directive

Allows/disallows the use of .htaccess files in project web root directory. Can be None (default), All, or any directive-type as specified in Apache documentation. Example: None

Apache serve local Files

This option tells Apache whether it should serve the (static) content itself. Currently, it will omit dynamic content, such as *.php, *.action, *.jsp, and *.do. Example: true

Application IP Type Given to Load Balancer

Specify the IP type where the application server is listening. Example: private

Application Listen Port

The port that the application service is listening on. Example: 8000

Application Name

Sets the directory for your application's web files (/home/webapps/Application Name/). If you have multiple applications, you can run the code checkout script multiple times, each with a different value for the 'Application Name' input, so each application will be stored in a unique directory. This must be a valid directory name. Do not use symbols in the name. Example: myapp

Backup Cron Hour (1)

Defines the hour when the backup will be taken. Use a value of 1-24, or set to 'Ignore' to create a backup every hour. Example: 10

Backup Cron Hour (2)

Defines the hour when the backup will be taken. Use a value of 1-24, or set to 'Ignore' to create a backup every hour. Example: 10

Backup Cron Minute (1)

Defines the minute of the hour when the backup will be taken. Use a value of 1-59, or set to 'Ignore' and a random minute will be calculated. Example: 10

Backup Cron Minute (2)

Defines the minute of the hour when the backup will be taken. Use a value of 1-59, or set to 'Ignore' and a random minute will be calculated. Example: 10

Backup Lineage (1)

The name associated with your primary and secondary database backups. It's used to associate them with your database environment for maintenance, restore, and replication purposes. Backup snapshots will automatically be tagged with this value (e.g. rs_backup:lineage=mysqlbackup). Backups are identified by their lineage name. Note: For servers running on Rackspace, this value also indicates the Cloud Files container to use for storing primary backups. If a Cloud Files container with this name does not already exist, one will automatically be created. Example: prod_db_lineage

Backup Lineage (2)

The name associated with your primary and secondary database backups. It's used to associate them with your database environment for maintenance, restore, and replication purposes. Backup snapshots will automatically be tagged with this value (e.g. rs_backup:lineage=mysqlbackup). Backups are identified by their lineage name. Note: For servers running on Rackspace, this value also indicates the Cloud Files container to use for storing primary backups. If a Cloud Files container with this name does not already exist, one will automatically be created. Example: prod_db_lineage

Backup Lineage Override

If defined, this will override the input defined for 'Backup Lineage' (block_device/devices/device2/backup/lineage) so that you can restore the volume from another backup that has as a different lineage name. The most recently completed snapshots will be used unless a specific timestamp value is specified for 'Restore Timestamp Override' (block_device/devices/device2/backup/timestamp_override). Example: prod_db_lienage_2

Backup Max Snapshots (1)

The maximum number of primary backups to keep in addition to those being rotated. Example: 60

Backup Max Snapshots (2)

The maximum number of primary backups to keep in addition to those being rotated. Example: 60

Backup Restore Timestamp Override (1)

Another optional variable to restore from a specific timestamp. Specify a string matching the timestamp tags on the volume snapshot set. You will need to specify the timestamp that's defined by the snapshot's tag (not name). For example, if the snapshot's tag is 'rs_backup:timestamp=1303613371' you would specify '1303613371' for this input. Example: 1303613371

Backup Restore Timestamp Override (2)

Another optional variable to restore from a specific timestamp. Specify a string matching the timestamp tags on the volume snapshot set. You will need to specify the timestamp that's defined by the snapshot's tag (not name). For example, if the snapshot's tag is 'rs_backup:timestamp=1303613371' you would specify '1303613371' for this input. Example: 1303613371

Block Device Mount Directory (1)

The directory of where to mount the block device (e.g., /mnt/storage). Example: /mnt/storage

Block Device Mount Directory (2)

The directory of where to mount the block device (e.g., /mnt/storage). Example: /mnt/storage

Block Device(s) to Operate On

The block device(s) to operate on. Can be a comma-separated list of device names or '*' to indicate all devices. Example: device1

Custom gems list

A space-separated list of optional gem(s). Format: ruby-Gem1:version ruby-Gem2:version ruby-Gem3. Example: mygem:1.0, yourgem:2.0

Custom rails/bin/ command

A comma-separated list of optional commands which will be executed in the app directory. Example: rake gems:install, rake db:create, rake get_common

Database Admin Password

The password of the database user with 'admin' privileges. Example: cred:DBADMIN_PASSWORD.

Database Admin Username

The username of the database user with 'admin' privileges. Example: cred:DBADMIN_USER.

Database Application Password

The password of the database user that has 'user' privileges. Example: cred:DBAPPLICATION_PASSWORD.

Database Application Username

The username of the database user that has 'user' privileges. Example: cred:DBAPPLICATION_USER.

Database Backup Lineage

The prefix that will be used to name/locate the backup of a particular database.Note: For servers running on Rackspace, this value also indicates the Cloud Files container to use for storing primary backups.If a Cloud Files container with this name does not already exist,the setup process creates one. Example: text:prod_db_lineage

Database DNS TTL Limit

The upper limit for the TTL of the master DB DNS record in seconds. This value should be kept low in the event of Master DB failure so that the DNS record updates in a timely manner. When installing the DB server, this value is checked in the DNS records. Input should be set for 300 when using CloudDNS. Example: 60

Database Master DNS Record ID

The unique identifier that is associated with the DNS A record of the master database server.The unique identifier is assigned by the DNS provider when you create a dynamic DNS A record. This ID is used to update the associated A record with the private IP address of the master server when this recipe is run. If you are using DNS Made Easy as your DNS provider, a 7-digit number is used (e.g., 4403234).Example:4403234

Database Master FQDN

The fully qualified domain name for the master database server. Example: db-master.example.com

Database Provider type

Database provider type to use on client side. This must be a string containing the provider cookbook name and (optionally) the version of the database. Example: db_mydatabase_1.0, db_mysql_5.1, db_mysql_5.5, db_postgres_9.1

Database Replication Network Interface

The network interface used for replication. WARNING: when selecting 'public' we highly recommend enabling SSL encryption, otherwise data could travel over insecure connections. Make sure you understand what you are doing before changing this value. Default: private

Database Replication Password

The password of the database user that has 'replication' privileges. Example: cred:DBREPLICATION_PASSWORD.

Database Replication Username

The username of the database user that has 'replication' privileges. Example: cred:DBREPLICATION_USER.

Database Restore Lineage Override

If defined, this will override the input defined for 'Backup Lineage' (db/backup/lineage) so that you can restore the database from another backup that has as a different lineage name. The most recently completed snapshots will be used unless a specific timestamp value is specified for 'Restore Timestamp Override' (db/backup/timestamp_override). Although this input allows you to restore from a different set of snapshots, subsequent backups will use 'Backup Lineage' to name the snapshots. Be sure to remove the 'Backup Lineage Override' input after the new master is operational. Example: text:new_db_lineage

Database Restore Timestamp Override

An optional variable to restore a database backup with a specific timestamp rather than the most recent backup in the lineage. You must specify a string that matches the timestamp tag on the volume snapshot. You will need to specify the timestamp that is defined by the snapshot's tag (not the name). For example, if the snapshot's tag is 'rs_backup:timestamp=1303613371' you would specify '1303613371' for this input. Example: 1303613371

Database Schema Name

Enter the name of the database schema to which applications will connect to.The database schema should have been created when the initial database was first set up. This input will be used to set the application server's database configuration file so that applications can connect to the correct schema within the database. NOTE: LAMP servers use this input for database dump backups in order to determine which schema will be backed up. Example: mydbschema

Database Slave DNS Record ID

The unique identifier that is associated with the DNS A record of a slave server. The unique identifier is assigned by the DNS provider when you create a dynamic DNS A record. This ID is used to update the associated A record with the private IP address of a slave server when this recipe is run. If you are using DNS Made Easy as your DNS provider, a 7-digit number is used (e.g., 4403234). Example:4403234

Database Slave FQDN

The fully qualified domain name for a slave database server. Example: db-slave.example.com

Domain Name

The domain name that you would like this node to have. Example: example.com

Domain Search Suffix

The domain search suffix you would like this node to have. Example: example.com

Dump Container

The cloud storage location where the dump file will be saved to or restored from. For Amazon S3, use the bucket name. For Rackspace Cloud Files, use the container name. Example: db_dump_bucket

Dump Prefix

The prefix that will be used to name/locate the backup of a particular database dump. Defines the prefix of the dump file name that will be used to name the backup database dump file, along with a timestamp. Example: prod_db_backup

Dump Storage Account ID

In order to write the dump file to the specified cloud storage location, you need to provide cloud authentication credentials. For Amazon S3, use your Amazon access key ID (e.g., cred:AWS_ACCESS_KEY_ID). For Rackspace Cloud Files, use your Rackspace login username (e.g., cred:RACKSPACE_USERNAME). For OpenStack Swift the format is: 'tenantID:username'. Example: cred:AWS_ACCESS_KEY_ID

Dump Storage Account Provider

Location where the dump file will be saved. Used by dump recipes to back up to remote object storage (complete list of supported storage locations is in input dropdown). Example: s3

Dump Storage Account Secret

In order to write the dump file to the specified cloud storage location, you need to provide cloud authentication credentials. For Amazon S3, use your AWS secret access key (e.g., cred:AWS_SECRET_ACCESS_KEY). For Rackspace Cloud Files, use your Rackspace account API key (e.g., cred:RACKSPACE_AUTH_KEY). Example: cred:AWS_SECRET_ACCESS_KEY

Dump Storage Endpoint URL

The endpoint URL for the storage cloud. This is used to override the default endpoint or for generic storage clouds such as Swift. Example: http://endpoint_ip:5000/v2.0/tokens

Enable security updates

Unfreezes software repositories after booting and installing packages, allowing for security updates to be installed.

Ephemeral File System Type

The type of file system that will be installed on the ephemeral device. By default, this input will be set to 'xfs'. This input is ignored on Redhat and Google cloud since we do not support 'xfs' on them. The 'ext3' file system will be set up by default on Redhat and Google cloud. Example: xfs

Firewall

Enables an iptables firewall for this server which allows port 22, 80 and 443 open by default. Use the sys_firewall::setup_rule recipe to enable/disable extra ports. Example: enabled

Firewall Rule

Enables or disables a firewall rule. Example: enable

Firewall Rule IP Address

Address can either be a network name, a network IP address (with /mask), or a plain IP address. The mask can either be a network mask or a plain number specifying the number of 1's at the left side of the network mask. Thus, a mask of 24 is equivalent to 255.255.255.0. A '!' argument before the address specification inverts the sense of the address. A value of 'any' allows any IP address. Example: any

Firewall Rule Port

Comma-separated list of ports to Enable or Disable. Example: 8080,8000

Firewall Rule Protocol

Firewall protocol use. Example: tcp

Force Promote to Master

If true, when promoting a slave to master, ignores making checks and changes to any current master. WARNING: setting this will promote a slave to a master with no replication until a new slave is brought up. Make sure you understand what you are doing before changing this value. Default: false

Force Reset Safety

Prevents the accidental running of the db::do_force_reset recipe. This recipe will only run if the input variable is overridden and set to "off". Example: text:off

Health Check URI

The URI that the load balancer will use to check the health of a server. It is only used for HTTP (not HTTPS) requests. Example: /

I/O Operations per Second (1)

The input/output operations per second (IOPS) that the volume can support. IOPS is currently only supported on Amazon EC2. Example: 500

I/O Operations per Second (2)
