Overview
<An overview of Swarm Cloud Gateway>
Prerequisites
CentOS 7.x Setup
Setup CentOS for Cloud Gateway
Minimal Mode | Host name | |
cg77-01.datacore.internal | cg77-02.datacore.internal | |
Application Network | IP Address | |
172.16.33.16/24 | 172.16.33.17/24 | |
Gateway | 172.16.33.1 | |
NTP | 172.16.33.10 |
Install Cloud Gateway
Info
Creating a user group/user/password applies when PAM authentication is used. You can create a user group via groupadd clusteradmins
, and a new user via adduser dcadmin -g clusteradmins -p datacore
& passwd datacore
commands.
Create a user group
groupadd clusteradmins
.Add a new user.
adduser dcadmin -g clusteradmins -p datacore passwd datacore
Update CentOS and install epel.
yum -y update yum -y install epel-release
Install NTP server and ensure that NTP starts on the system boot.
yum -y install chrony systemctl enable chronyd systemctl start chronyd
Install Java 8 JDK
yum -y install java-1.8.0-openjdk
.Configure the firewall to allow Cloud Gateway
vi /usr/lib/firewalld/services/swarm_gateway.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>
Restart the firewall service.
Add Cloud Gateway firewall rule (permanent) via
firewall-cmd --permanent --add-service swarm_gateway
command.Reload the firewall service
firewall-cmd --reload
.Unzip Swarm 14.0 bundle package to
/root/datacore
.From the downloaded Swarm bundle, get the latest gateway and UI RPMs.

Install Swarm RPM public key included with the distribution bundle using
rpm –import RPM-GPG-KEY
.Install Cloud Gateway components
yum -y install caringo-gateway-7.8.0-1.noarch.rpm
.Complete the IDSYS document for PAM user authentication
vi /etc/caringo/cloudgateway/idsys.json
.{"pam": { "name" : "idsys-pam", "description": "PAM identity management configuration", "cookieName": "token", "tokenPath": "/.TOKEN/", "tokenAdmin": "dcadmin@" }}
Complete policy document for the access control
vi /etc/caringo/cloudgateway/policy.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" } ] }
Install Gateway WebUI
yum -y install caringo-gateway-webui-7.5.0-1.noarch.rpm
.Edit Cloud Gateway configure file
/etc/caringo/cloudgateway/gateway.cfg
.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.
Set hosts for the storage cluster nodes (IP address of storage nodes).
Set indexerHosts to Elasticsearch Servers (IP address of Elasticsearch nodes).
Enable S3.
Enable Cluster Admin on the gateway server. It will install Swarm Storage UI.
Enable Management Port 91. The admin user and password must be the same as configured in SCS.
Set admin.username
Set admin.password
# Following are only needed when enabling cluster_admin managementPort = 91 managementUser = dcadmin managementPassword = datacore
Enable metering.
# # gateway.cfg -- configuration file for Caringo CloudScaler Gateway server # # Please read the CloudScaler Gateway Administration Guide for an explanation # of the parameters in this configuration file. # # Basic Configuration Steps: # ------------------------- # # 1. Set '[gateway]adminDomain' to administrative domain's name # # 2. Use the Swarm static locator for the backend cluster: # - Set '[storage_cluster]locatorType' to 'static' # - Set '[storage_cluster]hosts' for your Swarm nodes # # 3. Configure the Elasticsearch metadata backend: # - Set '[storage_cluster]indexerHosts' to the metadata search servers # # 4. If the S3 protocol is used: # - Ensure that bindAddress:bindPort does not conflict with SCSP # # # NOTE: For production use, you will need to adjust the thread counts, # connection limits, connection time outs, and the space/limits # for the HTTP multi-part spool. # # # Client communications and handling # [gateway] adminDomain = Lab1GatewayAdminDomain threads = 200 # multipartSpoolDir = /var/spool/cloudgateway # multipartUsageAllowed = 50 # sanitizeErrors = false # enablePasswordEncryption = false # legacyOnlyMode = false # # Storage cluster back-end configuration # [storage_cluster] locatorType = static hosts = 192.168.9.143 192.168.9.144 192.168.9.145 # port = 80 # dataProtection = immediate # blockUndeletableWrites = true indexerHosts = 192.168.9.21 192.168.9.22 192.168.9.23 # indexerPort = 9200 # indexerSocketTimeout = 120 # maxConnectionsPerRoute = 100 # maxConnections = 250 # connectTimeout = 60 # socketTimeout = 120 # idleTimeout = 120 # continueWaitTimeout = 30 # Following are only needed when enabling cluster_admin managementPort = 91 managementUser = dcadmin managementPassword = datacore # # SCSP front-end protocol # [scsp] enabled = true bindAddress = 0.0.0.0 bindPort = 80 # Set the following if this Gateway is the target of a push-style replication feed. # See 'Replication Feeds' in the Swarm documentation for details. # allowSwarmAdminIP = list,of,node,ips -or- all allowSwarmAdminIP = all # Set these to the external ports on your proxy, if using one #externalHTTPPort = 80 #externalHTTPSPort = 443 # # S3 front-end protocol # [s3] enabled = true bindAddress = 0.0.0.0 bindPort = 8090 # Set these to the external ports on your proxy, if using one #externalHTTPPort = 80 #externalHTTPSPort = 443 # # Cluster management protocol # [cluster_admin] enabled = true bindAddress = 0.0.0.0 bindPort = 91 # secretKey = yoursecretkeyhere # Set these to the external ports on your proxy, if using one #externalHTTPPort = 91 #externalHTTPSPort = 1443 # # Internal "folder listing service" config # [folder_listings] # enhancedListingConsistency = true # force ES index flush before query # feedCheckInterval = 60000 # in milliseconds, how often to check for non-searchable domains (search feed filters) # suppressNonSearchableError = false # suppress 412 error when searching non-searchable domain # # Caching timers : 0 == disabled # [caching] # authRefresh = 300 # tokenRefresh = 300 # idsysRefresh = 300 # policyRefresh = 300 # xformRefresh = 300 # metadataRefresh = 300 # domainExistenceRefresh = 300 # # Metering Support # [metering] enabled = true # flushIntervalSeconds = 300 # retentionDays = 100 # storageSampleIntervalSeconds = 3600 # # Quota Support # [quota] enabled = false smtpHost = localhost mailFrom = donotreply@localhost # mailSubjectTemplate = Quota state change notification # mailTemplate = Metric %metric% changed to %state% state in %contextType% %contextName%. # smtpPort = 25 # smtpUser = # smtpPassword = # minRefreshDeadline = 60 # maxRefreshDeadline = 3600 # numRefreshThreads = 4 # maxRefreshRetries = 3 # maxQueueSize = 10000 # queryTTL = 3600 # refreshRetryDelay = 10 # refreshIdleSleep = 3 # # Prometheus metrics capturing support # [metrics] metricsEnabled = true # default enabled # metricsPort = 9100 # port where to scrape for metrics # # Remote synchronous write support (RSW) # [rsw] # enabled = true # default enabled # maxWaitTime = -1 # timeout in seconds to wait for RSW completion, -1 means no timeout # enableInfoLogging = true # default true, log RSW operations at INFO level # # Object Lock Support (Retention, LegalHold) # [object_locking] # scspDeleteUsesS3Logic = true # Allows delete of a locked current object version (via delete marker) # retentionMaxYears = 100 # Max retention duration
