      Introduction

      Steps in Getting Started

      Introduction | Prepare | Install | Verify

      In this Getting Started topic we cover how to install the Sync Gateway package on various common platforms and how to check the installation’s success.

      You can install Sync Gateway on any of the supported operating systems.

      On completion of this topic you should have a working Sync Gateway that you can extend and configure to meet your business needs.

      Installation Process

      The installation process first deploys the Sync Gateway package, then defines and starts an example instance of Sync Gateway running as a service.

      By default Sync Gateway bases its initial setup on an example configuration file serviceconfig.json, provided in the examples directory. This initial configuration has limited functionality. It is intended primarily to verify the success of the installation by proving a connection to Sync Gateway can be made.

      Using Your Own Configuration

      Sync Gateway’s initial setup uses configuration details from a file its install script creates (sync_gateway.json, or serviceconfig.json on Windows).

      To provide your own configuration to Sync Gateway, you can either:

      • Continue to provide your config in the default file. You will need to restart Sync Gateway after each change.

      • Run Sync Gateway from a command-line. That way you can provide a path to the required config file as a parameter.

      • Change the service to use the required configuration file path.
        Instructions on how to do this are given in the Install section for each of the platforms as they differ lightly.

      You should refer to the Configuration Overview for more on the configuration process and to the Configuration Schema for details on the configuration options. We also discuss more on the initial configuration in the next Getting Started section — see: Verify. Also, the installation package itself contains example configuration files — see the appropriate install platform section for details on their location.

      /lib/systemd/system/sync_gateway.service or /usr/lib/systemd/system/sync_gateway.service

      Run

      In a production environment you will normally run Sync Gateway as a service. However, it can also be run directly from a command line, for convenience of testing.

      • Run as a Service

      • Command Line

      Using systemd
      systemctl start sync_gateway
      systemctl stop sync_gateway
      Using init
      service sync_gateway start
      service sync_gateway stop
      Start
      (1)
      /opt/couchbase-sync-gateway/bin/sync_gateway <path-to-configuration-file> (2)
      1 Where /opt/couchbase-sync-gateway/ is the location into which you deployed the Sync Gateway package.
      2 Where <path-to-configuration-file> resolves to a JSON format file containing the Sync Gateway configuration, for example, /home/sync_gateway/sync-gateway-config.json
      Stop

      You can stop Sync Gateway instances started in this way by using Ctrl+C. There is no specific shutdown procedure and it is safe to stop it at any time. For other command-line options — see Command Line Options

      Configuration

      To change the default configuration file path of an existing Sync Gateway service you need to edit the service descriptor.

      For systemd this will be sync_gateway.service in either /lib/systemd/system/sync_gateway.service or /usr/lib/systemd/system/sync_gateway.service

      You will need to find and replace the path in following line with your required path: Environment="CONFIG=/home/sync_gateway/sync_gateway.json"

      One way to do this is to use systemctl
      1. Ensure the new file path includes a useable Sync Gateway configuration file.

      2. Stop the service.

      3. Copy the existing sync_gateway.service file to a safe location as a back-up.

      4. Use sudo systemctl --full edit sync_gateway to edit the service
        This will create a temporary file in /etc/systemd/system/sync_gateway.d containing your changes. This file is picked-up and applied when the daemon reloads. Note, systemctl edit automatically reloads the edited unit.

      5. Replace the path in Environment="CONFIG=/home/sync_gateway/sync_gateway.json" with your required path

      6. Save the changes
        When the daemon reload completes, Sync Gateway will restart using the required configuration file.

      • The path to the executable uses Windows' short name notation

      • <path-to-configuration-file> resolves to a JSON format file containing the Sync Gateway configuration, for example, {home-location-windows}sync-gateway-config.json

      Stop

      You can stop Sync Gateway instances started in this way by using Ctrl+C. There is no specific shutdown procedure and it is safe to stop it at any time. For other command-line options — see Command Line Options

      Configuration

      To change the default configuration file path of an existing Sync Gateway service you need to edit the service descriptor.

      For Windows, the configuration path is provided as a command line parameter embedded within the SyncGateway service’s binpath.

      One way to edit the binpath value is to use Windows' Service Control Manager’s command line utility sc.exe config. See the Syntax of the sc.exe Command and an example of the command in use in Example 1.

      Syntax of the sc.exe Command

      The format of the sc.exe command is shown below. For presentation purposes it is split over several lines. It should be input as a single line.

      sc <remote-server-name> (1)
        config (2)
        SyncGateway (3)
        binpath= (4)
        " (5)
        [path-to-sg-windows.exe] start [path-to-sync_gateway.exe] (6)
        [path-to-config-file] (7)
        [path-to-error-logs] (8)
        " (9)
      1 Omit the <remote-server-name> parameter if the service is local
      2 Specifies the function we are using, config, in this instance
      3 Identifies the service being changed
      4 Specifies the string value of the path to the binary to be run, and any command line parameters. The rules for formatting the binpath value are quite complex:
      • The entire string value must be enclosed in quotes

      • There must be one space (only) following the equals sign and none before it

      • Each of the [path-to …​] elements must themselves be enclosed in quotes. These inner quotes must be escaped (for example \" …​ \")

      5 Opening quotes for the binpath, preceded by a single space.
      6 Path to the binaries.
      7 You can provide the required configuration file path name here in the form:
      \"path/to/file/name.json\"
      8 You can provide the required log file path name here in the form:
      \"path/to/file/name.log\"
      9 Closing quotes for the binpath, preceded by a single space.
      Example 1. Sample sc.exe Use

      This example changes the configuration file name from serviceconfig.json to sync-gateway-config.json

      sc config SyncGateway binpath= "\"C:\Program Files\Couchbase\Sync Gateway\sg-windows.exe\" start \"C:\Program Files\Couchbase\Sync Gateway\sync_gateway.exe\" \"C:\Program Files\Couchbase\Sync Gateway\sync-gateway-config.json\" \"C:\Program Files\Couchbase\Sync Gateway\var\lib\couchbase\logs\sync_gateway_error.log\""

      Install for Mac OS

      In this Section

      Install | Install Locations | Run | Configuration

      Download

      Download the required edition of Sync Gateway from the downloads page.

      Install

      1. Unpack the .zip file to the /opt directory.

        sudo unzip -d /opt couchbase-sync-gateway-enterprise_2.8.4_x86_64.zip
      2. Create a new macOS user.

        sudo sysadminctl -addUser sync_gateway

        If the operation is successful, you will get the following output.

        sysadminctl ----------------------------
        sysadminctl No clear text password or interactive option was specified (adduser, change/reset password will not allow user to use FDE) !
        sysadminctl ----------------------------
        sysadminctl Creating user record…
        sysadminctl Assigning UID: 505
        sysadminctl Creating home directory at /Users/sync_gateway
      3. Create a new group and add the sync_gateway user to that group.

        sudo dseditgroup -o create sync_gateway
        sudo dseditgroup -o edit -a sync_gateway -t user sync_gateway
      4. Define the Sync Gateway Service

        This script will define and load the service, which is set it to automatically restart.

        Other scripts in the service directory are available to update or uninstall the service.

        cd /opt/couchbase-sync-gateway//service
        sudo ./sync_gateway_service_install.sh <optional-args> (1)
        1 Note that you can, by using optional parameters, provide alternative file paths for the Sync Gateway configuration file (--cfgpath=) or log files () path (--logsdir=). These will be used instead of the default path whenever the service starts.

        So, for example:
        sudo ./sync_gateway_service_install.sh --cfgpath=sync-gateway-config.json

      5. When the install is complete the sync_gateway service will be running

        To stop/start the sync_gateway service, use the methods show in Run

      sudo launchctl unload -w /Library/LaunchDaemons/com.couchbase.mobile.sync_gateway.plist (2)
      1 Here we load, and automatically start, the default sync_gateway service
      2 Here we unload the default sync_gateway service. Note that it is not sufficient to stop the service. It is configured to automatically restart.
      Start
      (1)
      /opt/couchbase-sync-gateway/bin/sync_gateway <path-to-configuration-file> (2)
      1 Where /opt/couchbase-sync-gateway/ is the location into which you deployed the Sync Gateway package.
      2 Where <path-to-configuration-file> resolves to a JSON format file containing the Sync Gateway configuration, for example, /users/sync_gateway/sync-gateway-config.json
      Stop

      You can stop Sync Gateway instances started in this way by using Ctrl+C. There is no specific shutdown procedure and it is safe to stop it at any time. For other command-line options — see Command Line Options

      Configuration

      To change the default configuration file path of an existing Sync Gateway service you need to edit the service descriptor.

      For Mac OS this will be the .plist file com.couchbase.mobile.sync_gateway.plist.

      One way to do this would be:
      1. Ensure the new file path includes a useable Sync Gateway configuration file

      2. Within a terminal, stop the service — see: start and stop the service

      3. Copy the existing com.couchbase.mobile.sync_gateway.plist file to a safe location as a back-up

      4. Open the com.couchbase.mobile.sync_gateway.plist file in an editor. You will need to use sudo

      5. Within the ProgramArguments section of the .plist, find and edit the configuration file path, which by default contains: <string>/Users/sync_gateway/sync_gateway.json</string>

      6. Save your changes

      7. Restart the service  — see: start and stop the service

      Check the Install

      To check Sync Gateway started successfully, you can now connect to it from a browser by using either:

      You should receive a response in the browser such as:
      {"couchdb":"Welcome","vendor":{"name":"Couchbase Sync Gateway","version":"2.8"},"version":"Couchbase Sync Gateway/{version-maint}(145;e3f46be) EE"}

      If you do encounter issues in getting an operational install of Sync Gateway, you can find some useful information in the log files. Refer to the Logging page for how to configure different logging levels to aid troubleshooting.
