Prerequisites
CentOS 7.x Setup
Setup CentOS for Cloud Gateway
Below is an example deployment for the site.

# # 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 |
Cluster Initialization
Once the configuration is complete, the Gateway must be initialized to ensure a proper runtime environment. This ensures the administrative domain exists within the storage cluster and also secures all plaintext passwords entered into the configuration files.
Use
systemctl stop cloudgateway
to ensure the Gateway is not runningRun
/opt/caringo/cloudgateway/bin/initgateway
to perform the initialization of the environment.Once initialization has successfully completed, start Cloud gateway and ensure that the gateway service is running on the system boot.
Code Block language bash systemctl start cloudgateway systemctl enable cloudgateway

Next, setup additional gateways. |
