Run Cluster by Yum Tools

Yum tools to run a ChubaoFS cluster for CentOS 7+ is provided. The list of RPM packages dependencies can be installed with:

$ yum install http://storage.jd.com/chubaofsrpm/latest/cfs-install-latest-el7.x86_64.rpm
$ cd /cfs/install

Set parameters of the ChubaoFS cluster in iplist.

  • [master][datanode] , [metanode] , [monitor] , [client] modules define IP addresses of each role.
  • #datanode config module defines parameters of DataNodes. datanode_disks defines path and reserved space separated by “:”. The path is where the data store in, so make sure it exists and has at least 30GB of space; reserved space is the minimum free space(Bytes) reserved for the path.
  • [cfs:vars] module defines parameters for SSH connection. So make sure the port, username and password for SSH connection is unified before start.
  • #metanode config module defines parameters of MetaNodes. metanode_totalMem defines the maximum memory(Bytes) can be use by MetaNode process.

For more configurations, please refer to Resource Manager (Master)Meta SubsystemData SubsystemClientMonitor.

Start the resources of ChubaoFS cluster with script install.sh . (make sure the Master is started first)

$ bash install.sh -h
Usage: install.sh [-r --role datanode or metanode or master or monitor or client or all ] [-v --version 1.5.1 or latest]
$ bash install.sh -r master
$ bash install.sh -r metanode
$ bash install.sh -r datanode
$ bash install.sh -r monitor
$ bash install.sh -r client

Check mount point at /cfs/mountpoint on client node defined in iplist .

Open http://consul.prometheus-cfs.local in browser for monitoring system(the IP of monitoring system is defined in iplist ).
