The following sections provide information and instructions on how to cluster the ESB Integration profile of WSO2 Enterprise Integrator (WSO2 EI) with a third-party load balancer.

...

Info

Note the following facts when configuring the load balancer:

These configurations are not required if your clustering setup does not have a load balancer.
Load balancer ports are HTTP 80 and HTTPS 443 in the deployment pattern shown in the above diagram. If your system uses any other ports, be sure to replace 80 and 443 values with the corresponding ports when you follow the configuration steps in this section.
The load balancer directs requests to the server on a round robin basis. For example, the load balancer will direct requests to node 1 (xxx.xxx.xxx.xx1) of the ESB Integration cluster as follows:
- HTTP requests will be directed to node 1 using the http://xxx.xxx.xxx.xx1/<service> URL via HTTP 80 port.
- HTTPS requests will be directed to node 1 using the https://xxx.xxx.xxx.xx1/<service> URL via HTTPS 443 port.
- The management console of node 1 will be accessed using the https://xxx.xxx.xxx.xx1/carbon/ URL via HTTPS 443 port.

...

Install NGINX Plus or Nginx community version configured in a server within your cluster network.

Create a VHost file (ei.http.conf) in the /etc/nginx/conf.d directory and add the following configurations. This configures NGINX Plus to direct the HTTP requests to the two ESB Integration nodes (xxx.xxx.xxx.xx1 and xxx.xxx.xxx.xx2) via the HTTP 80 port using the http://ei.wso2.com/ URL.

Follow the instructions below to create SSL certificates for both ESB Integration nodes.
Tip
Enter the host name (ei.wso2.com) as the common name when creating keys.
1. Execute the following command to create the Server Key:
  Code Block
  $sudo openssl genrsa -des3 -out server.key 1024
2. Execute the following command to request to sign the certificate:
  Code Block
  $sudo openssl req -new -key server.key -out server.csr
3. Execute the following commands to remove the passwords:
  Code Block
  $sudo cp server.key server.key.org $sudo openssl rsa -in server.key.org -out server.key
4. Execute the following command to sign your SSL Certificate:
  Code Block
  $sudo openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt
5. Execute the following command to add the certificate to the <EI_HOME>/repository/resources/security/client-truststore.jks file:
  Code Block
  keytool -import -trustcacerts -alias server -file server.crt -keystore client-truststore.jks
  Tip
  Give the default password wso2carbon when prompted.
Execute the following command to restart the NGINX Plus server:
Code Block
$sudo service nginx restart
Tip
Execute the following command if you do not need to restart the server when you are simply making a modification to the VHost file:
Code Block
$sudo service nginx reload

...

All profiles of WSO2 EI uses a database to store information such as user management details and registry data. All nodes in the cluster must use one central database for config and governance registry mounts. You can create the following databases and associated datasources.

Database Name	Description
WSO2_USER_DB	JDBC user store and authorization manager
`REGISTRY_DB`	Shared database for config and governance registry mounts in the product's nodes
`REGISTRY_LOCAL1`	Local registry space in Node 1
`REGISTRY_LOCAL2`	Local registry space in Node 2

Warning
It is recommended to use an industry-standard RDBMS such as Oracle, PostgreSQL, MySQL, MS SQL, etc. for most enterprise testing and production environments. However, you can also use the embedded H2 database only for the `REGISTRY_LOCAL1` and `REGISTRY_LOCAL2`.

...

Add the following configurations to the <EI_HOME>/conf/registry.xml file of each ESB Integration node to configure the shared registry database and mounting details. This ensures that the shared registry for governance and configurations (i.e., the REGISTRY_DB database) mounts on both ESB Integration nodes.

Note

Note the following when adding these configurations:

The existing dbConfig called wso2registry must not be removed.
The datasource you specify in the <dbConfig name="sharedregistry"> tag must match the JNDI Config name you specify in the <EI_HOME>/conf/datasources/master-datasources.xml file.
The registry mount path denotes the type of registry. For example, ”/_system/config” refers to configuration Registry, and "/_system/governance" refers to the governance registry.
The <dbconfig> entry enables you to identify the datasource you configured in the <EI_HOME>/conf/datasources/master-datasources.xml file. The unique name "sharedregistry" refers to that datasource entry.
The <remoteInstance> section refers to an external registry mount. Specify the read-only/read-write nature of this instance, caching configurations and the registry root location in this section.

Also, specify the cache ID in the <remoteInstance> section. This enables caching to function properly in the clustered environment.

Note

Cache ID is the same as the JDBC connection URL of the registry database. This value is the Cache ID of the remote instance. It should be in the format of $database_username@$database_url, where $database_username is the username of the remote instance database and $database_url is the remote instance database URL. This cacheID denotes the enabled cache. In this case, the database it should connect to is REGISTRY_DB, which is the database shared across all the nodes. You can find that in the mounting configurations of the same datasource that is being used.

Define a unique name in the <id> tag for each remote instance. This is then referred to from mount configurations. In the above example, the unique ID for the remote instance is "instanceId".
Specify the actual mount path and target mount path in each of the mounting configurations. The target path can be any meaningful name. In this instance, it is "/_system/eiconfig".

</mount>

Configuring the

...

Integration profile node

Do the following configurations for all nodes of your cluster.

Open the <EI_HOME>/conf/datasources/master-datasources.xml file, and configure the datasources to point to the relevant databases for each ESB Integration node.

Tip
Replace the username, password, and database URL of your MySQL environment accordingly. If you have not enabled SSL, append the `useSSL=false` property to the value of the `<url>` property.

Add the following configuration in the <EI_HOME>/conf/user-mgt.xml file to configure the user stores.

Tip
Enter the datasource information for the user store that you configured in the `<EI_HOME>/conf/`datasources`/master-`datasources`.`xml file. You can change the admin username and password as well. However, you should do this before starting the server.

Code Block

  </AdminUser>
  <EveryOneRoleName>everyone</EveryOneRoleName>
  <Property name="dataSource">jdbc/WSO2UMDB</Property>
</Configuration>

Update the dataSource property in all nodes in the <EI_HOME>/conf/user-mgt.xml file as shown below to configure the datasource:
Code Block
<Property name="dataSource">jdbc/WSO2UMDB</Property>

Open the <EI_HOME>/conf/axis2/axis2.xml file for each of the two ESB Integration nodes, and appply the following cluster configurations:

Enable clustering for each node as follows:

Code Block
<clustering class="org.wso2.carbon.core.clustering.hazelcast.HazelcastClusteringAgent" enable="true">

Set the membership scheme to "wka" to enable the well-known address registration method as shown below. Each node sends cluster initiation messages to the WKA members.
Code Block
<parameter name="membershipScheme">wka</parameter>
Specify the name of the cluster to which the node joins:
Code Block
<parameter name="domain">wso2.ei.domain</parameter>

Specify the host to communicate cluster messages. For example, if the IP addresses of the two ESB Integration nodes are xxx.xxx.xxx.xx1 and xxx.xxx.xxx.xx2, they should be specified in the configuration as shown below.

Specify the port to communicate cluster messages as follows:

Code Block
<parameter name="localMemberPort">4100</parameter>

Info
This port number is not affected by the port offset value specified in the `<EI_HOME>/conf/carbon.`xml file. If this port number is already assigned to another server, the clustering framework automatically increments this port number. However, if there are two servers running on the same machine, ensure that a unique port is set for each server.

Specify the well-known members in the cluster as shown below. For example, when you configure one ESB Integration node, you need to specify the other nodes in the cluster as well-known members as shown below. The port value for the WKA node must be the same value as it's localMemberPort (in this case it is 4100).

Info
You can also use IP address ranges for the hostname (e.g., 192.168.1.2-10). However, you can define a range only for the last portion of the IP address. Smaller the range, the faster the time it takes to discover members since each node has to scan a lesser number of potential members.

Specify the port offset value in the <EI_HOME>/conf/carbon.xml file.

Warning
This step is optional and only required if all server instances are running on the same machine. This is not recommended for production environments. Change all ports used in your configurations based on the offset value if you are setting a port offset.

title	Click here for more information on configuring the port offset.

When you run multiple products/clusters or multiple instances of the same product on the same server or virtual machines (VMs), change their default ports with an offset value to avoid port conflicts. An offset defines the number by which all ports in the runtime (e.g., HTTP(S) ports) are increased. For example, if the default HTTP port is 9763 and the offset is 1, the effective HTTP port will change to 9764. For each additional product instance, set the port offset to a unique value. The offset of the default ports is zero.

The port value will automatically increase as shown in the Port Value column in the following table, allowing all five WSO2 product instances or servers to run on the same machine.

WSO2 product instance	Port Offset	Port Value
WSO2 server 1	0	9443
WSO2 server 2	1	9444
WSO2 server 3	2	9445
WSO2 server 4	3	9446
WSO2 server 5	4	9447

Edit the <EI_HOME>/conf/carbon.xml file as follows to configure the hostname: <HostName>ei.wso2.com</HostName>
Add the host entries to your DNS, or “/etc/hosts” file (in Linux) in all the nodes of the cluster to map the hostnames to the IP addresses. For an example, you can map the IP address of the database server. In this example, MySQL is used as the database server, so <MYSQL-DB-SERVER-IP> is the actual IP address of the database server and the host entry is as follows: <IP-of-MYSQL-DB-SERVER> carbondb.mysql-wso2.com

Edit the <EI_HOME>/conf/tomcat/catalina-server.xml file as follows:

Add proxyPort="80" to the org.apache.coyote.http11.Http11NioProtocol class with the port defined as 9763:
Code Block
language xml
<Connector protocol="org.apache.coyote.http11.Http11NioProtocol" port="9763" proxyPort="80" ... />
Add proxyPort="443" to the org.apache.coyote.http11.Http11NioProtocol class with the port defined as 9443:
Code Block
language xml
<Connector protocol="org.apache.coyote.http11.Http11NioProtocol" port="9443" proxyPort="443" ... />

The Connector protocol tag sets the protocol to handle incoming traffic. The default value is HTTP/1.1, which uses an auto-switching mechanism to select either a blocking Java-based connector or an APR/native connector. If the PATH (Windows) or LD_LIBRARY_PATH (on most UNIX systems) environment variables contain the Tomcat native library, the APR/native connector will be used. If the native library cannot be found, the blocking Java-based connector will be used. Note that the APR/native connector has different settings from the Java connectors for HTTPS.

The non-blocking Java connector used is an explicit protocol that does not rely on the auto-switching mechanism described above. The following is the value used:
org.apache.coyote.http11.Http11NioProtocol

The TCP port number is the value that this Connector will use to create a server socket and await incoming connections. Your operating system will allow only one server application to listen to a particular port number on a particular IP address. If the special value of 0 (zero) is used, Tomcat will select a free port at random to use for this connector. This is typically only useful in embedded and testing applications.

Deploy artifacts to each product deployment location.

Info
Use a deployment synchronization mechanism to synchronize the artifacts in the `<EI_HOME>/repository/deployment/` directory. Always deploy artifacts first to the ESB Integration server profile node with the registry configured as read/write. Next, deploy the artifacts to the other nodes.

Restart the configured load balancer.
Execute the following command and start both ESB Integration nodes: sh <EI_HOME>/bin/integrator.sh

Check for ‘member joined’ log messages in all consoles.

Info

title	Additional information on logs and new nodes

When you terminate one node, all nodes identify that the node has left the cluster. The same applies when a new node joins the cluster. If you want to add another new node, copy existing node without any changes if you are running it on a new server (such as xxx.xxx.xxx.184). If you intend to use the new node on a server where another WSO2 product is running, use a copy of node and change the port offset accordingly in the <EI_HOME>/conf/carbon.xml file. You also have to change localMemberPort in the <EI_HOME>/conf/axis2/axis2.xml file if that product has clustering enabled. Also, map all hostnames to the relevant IP addresses when creating a new node. The log messages indicate if the new node joins the cluster.

Access the management console through the LB using the following URL: https://xxx.xxx.xxx.xx1:443/carbon
Test load distribution via the following URLs: http://xxx.xxx.xxx.xx1:80/ or https://xxx.xxx.xxx.xx1:443/
Add a sample proxy service with the log mediator in the inSequence so that it will display logs in the terminals, and then observe the cluster messages sent.
Send a request to the endpoint through the load balancer to verify that the proxy service is activated only on the active node(s) while the nodes remain passive. This is to test that the load balancer manages the active and passive states of the nodes, activating nodes as needed and leaving the rest in passive mode. For example, you would send the request to the following URL: http://{Load_Balancer_Mapped_URL_for_worker}/services/{Sample_Proxy_Name
