Prerequisites

...

1. Create a user group via groupadd clusteradmins.

2. Add a new user.

   Code Block
   language bash
   adduser dcadmin -g clusteradmins -p datacore  passwd datacore

3. Update CentOS and install epel.

   Code Block
   language bash
   yum -y update yum -y install epel-release

4. Install NTP server and ensure that NTP starts on the system boot.

   Code Block
   language bash
   yum -y install chrony  systemctl enable chronyd  systemctl start chronyd

5. Install Java 8 JDK via yum -y install java-1.8.0-openjdk.

6. Configure the firewall to allow Cloud Gateway vi /usr/lib/firewalld/services/swarm_gateway.xml.

   Code Block
   language xml
   <?xml version="1.0" encoding="utf-8"?>  <service>    <short>SwarmGateway</short>    <description>Elasticsearch server REST API, which is based on http traffic.</description>    <port protocol="tcp" port="80"/>    <port protocol="tcp" port="91"/>    <port protocol="tcp" port="8090"/>    <port protocol="tcp" port="9100"/>  </service>

7. Restart the firewall service.

8. Add Cloudgateway Cloud Gateway firewall rule (permanent) via firewall-cmd --permanent --add-service swarm_gateway command.

9. Reload the firewall service firewall-cmd --reload.

10. Unzip Swarm 14.0 bundle package to /root/datacore.

11. From the downloaded Swarm bundle, get the latest gateway and UI RPMs.

    Code Block
    language bash
    ll ~/datacore/Gateway/  total 57352 -rw-r--r--. 1 root root 58718208 Dec 16 22:37 caringo-gateway-7.7.1-2.noarch.rpm  -rw-r--r--. 1 root root      395 Dec 16 22:37 README.txt  -rw-r--r--. 1 root root     1927 Oct  2 04:17 RPM-GPG-KEY ll ~/datacore/UI/  total 21616  -rw-r--r--. 1 root root  2835590 Oct  2 04:17 caringo-gateway-webui-7.4.0-1.noarch.rpm  -rw-r--r--. 1 root root 19286001 Dec 16 22:37 caringo-storage-webui-3.4.0-1.noarch.rpm  -rw-r--r--. 1 root root      359 Dec 16 22:37 README.txt  -rw-r--r--. 1 root root     1927 Oct  2 04:17 RPM-GPG-KEY

12. Install Swarm RPM public key included with the distribution bundle using rpm –import RPM-GPG-KEY.

13. Install Cloud Gateway components yum -y install caringo-gateway-7.8.0-1.noarch.rpm.

14. Complete the IDSYS document for PAM user authentication vi /etc/caringo/cloudgateway/idsys.json. 
    

    Code Block
    language json
    {"pam": {    "name" : "idsys-pam",    "description": "PAM identity management configuration",    "cookieName": "token",    "tokenPath":  "/.TOKEN/",    "tokenAdmin": "dcadmin@" }}

15. Complete policy document for the access control vi /etc/caringo/cloudgateway/policy.json.

    Code Block
    language json
    {    "Id": "Root policy -- grant admins full access to everything",    "Statement": [      { "Sid": "Grant admins full access",        "Resource": "*",        "Principal": {          "user": ["dcadmin@"],          "group": ["clusteradmins@"]        },        "Action": [ "*" ],        "Effect": "Allow"      }    ]  }

16. Install Gateway WebUI yum -y install caringo-gateway-webui-7.5.0-1.noarch.rpm.

17. Edit Cloudgateway Cloud Gateway configure file /etc/caringo/cloudgateway/gateway.cfg.

    1. Set adminDomain for the administrative domain name to be created. It is recommended to always set a unique name for each Swarm cluster to prevent replication collision between Source and Target Swarm Cluster. Set a unique name for each Swarm cluster to prevent replication collision.

    2. Set hosts for the storage cluster nodes (i.e., IP address of storage nodes).

    3. Set indexerHosts to Elasticsearch Servers (i.e., IP address of Elasticsearch nodes).

    4. Enable S3.

    5. EnableCluster Admin on the gateway server. It will install Swarm Storage UI.

    6. Enable Management Port 91. The admin user and password must be the same as configured in SCS.

       1. Set admin.username

       2. Set admin.password

          Code Block
          language bash
          # Following are only needed when enabling cluster_admin  managementPort = 91  managementUser = dcadmin  managementPassword = datacore

    7. Enable metering.
