Yum Deployment

You can use the yum tool to quickly deploy and start the CubeFS cluster in CentOS 7+ operating system.

Get Software

The RPM dependencies of this tool can be installed with the following command:

Note

The cluster is managed through Ansible, please make sure that Ansible has been deployed. ansible installation command ：pip3 install ansible

# x86 version
$ yum install https://cubefs-rs.heytapdownload.com/rpm/3.3.2/cfs-install-3.3.2-el7.x86_64.rpm
# arm version
$ yum install https://cubefs-rs.heytapdownload.com/rpm/3.3.2/cfs-install-3.3.2-el7.aarch64.rpm
$ cd /cfs/install
$ tree -L 3

Note

The arm version deployment requires Glibc version 2.32 and above

Configuration Instructions

You can modify the parameters of the CubeFS cluster in the iplist file according to the actual environment.

• master, datanode, metanode, objectnode, monitor, client contain the IP addresses of each module member.
• The cfs:vars module defines the SSH login information of all nodes, and the login name and password of all nodes in the cluster need to be unified in advance.

Master Config

Defines the startup parameters of each Master node.

Parameter	Type	Description	Required
master_clusterName	string	Cluster name	Yes
master_listen	string	Port number for http service listening	Yes
master_prof	string	Port number for golang pprof	Yes
master_logDir	string	Directory for storing log files	Yes
master_logLevel	string	Log level, default is info	No
master_retainLogs	string	How many raft logs to keep	Yes
master_walDir	string	Directory for storing raft wal logs	Yes
master_storeDir	string	Directory for storing RocksDB data. This directory must exist. If the directory does not exist, the service cannot be started.	Yes
master_exporterPort	int	Port for prometheus to obtain monitoring data	No
master_metaNodeReservedMem	string	Reserved memory size for metadata nodes. If the remaining memory is less than this value, the MetaNode becomes read-only. Unit: bytes, default value: 1073741824	No

For more configuration information, please refer toMaster Configuration Instructions.

DataNode Config

datanode_exporterPort	string	Port for the monitoring system to collect data	No
datanode_disks	string array	Format: PATH:RETAIN, PATH: disk mount path, RETAIN: the minimum reserved space under this path, and the disk is considered full if the remaining space is less than this value. Unit: bytes. (Recommended value: 20G~50G)	Yes

For more configuration information, please refer to DataNode Configuration Instructions.

Note

CubeFS supports mixed deployment. If mixed deployment is adopted, pay attention to modifying the port configuration of each module to avoid port conflicts. the path corresponding to the datanode_disks configuration needs to be manually created before the datanode can be started

Start the Cluster

Use the install.sh script to start the CubeFS cluster, and make sure to start the Master first.

$ bash install.sh -h
Usage: install.sh -r | --role [datanode | metanode | master | objectnode | client | all | createvol ]
$ bash install.sh -r master
$ bash install.sh -r metanode
$ bash install.sh -r datanode
$ bash install.sh -r objectnode

$ bash install.sh -r createvol
$ bash install.sh -r client

After all roles are started, you can log in to the node where the client role is located to verify whether the mount point /cfs/mountpoint has been mounted to the CubeFS file system.
