CentOS

Note

To install JetStream, you will need to either be logged in as root or be an administrative user using sudo. The examples below use sudo.

JetStream will install systemd service units for jetstream-server and jetstream-relay services, with /etc/jetstream-server.rsp and /etc/jetstream-relay.rsp configuration files respectively. Both services are disabled by default.

New Installation

To install JetStream on CentOS, run the following:

# sudo rpm -i go-jetstream-<version>.x86_64.rpm

Enable and start the service:

# sudo systemctl enable jetstream-server
# sudo systemctl start jetstream-server

CentOS runs the firewalld firewall by default, so you may also need to add a firewall exception, for instance:

# sudo firewall-cmd --permanent --zone=public --add-port=8886/tcp --add-port=8886/udp
# sudo systemctl restart firewalld

Your server should now be running.

Note

Additional UDP ports may be opened for concurrent transfers. See Network/Firewall.

Update Existing Installation

To update JetStream on CentOS, run:

# sudo rpm -U go-jetstream-<version>.x86_64.rpm
# sudo systemctl daemon-reload
# sudo systemctl restart jetstream-server

Uninstall

To uninstall JetStream on CentOS, run:

# sudo rpm -e go-jetstream

Check Service

You can check if the JetStream service is running by running the systemctl status command. Under normal circumstances, the command should report that the process is active(running) under the Active heading. For example:

# systemctl status jetstream-server
● jetstream-server.service - Go:JetStream server service
   Loaded: loaded (/usr/lib/systemd/system/jetstream-server.service; enabled; vendor preset: disabled)
   Active: active (running) since Thu 2019-10-03 15:02:36 PDT; 15min ago
 Main PID: 1276 (jetstream)
    Tasks: 27
   CGroup: /system.slice/jetstream-server.service
           ├─1276 /usr/local/bin/jetstream server @/etc/jetstream-server.rsp
           └─1629 /usr/local/bin/jetstream server @/etc/jetstream-server.rsp

Check Server

You can check that the server is active by making a simple API call on the command-line.

# /usr/local/bin/jetstream api --no-auth getServerInfo

 "license": {

 },
 ...

}

Active Directory

If your system is integrated with Active Directory, you may need to enable JetStream authentication in sssd. See Active Directory Integration.

Firewalls

There may be internal or external firewalls preventing connections. See Firewalls for tips on firewall configuration.
