一:编辑配置文件:
1.1配置文件:
vim /etc/crate/crate.yml
1.2编辑crate.yml 的集群名称在166行附近:
cluster.name: crate-xxx
1.3编辑node节点名称202行附近:
node.name: node-01
1.4主节点设置209行附近与1.9master高可用互相匹配:
node.master: true
1.5集群接口400行附近:
transport.tcp.port: 4300
1.6后备恢复点425行附近:
#值要大于discovery.zen.minimum_master_nodes且小于等于gateway.expected_nodes
gateway.recover_after_nodes: 2
1.7集群总节点数434行附近:
gateway.expected_nodes: 3
1.8Discovery集群发现510行附近:
discovery.zen.ping.unicast.hosts:
- 192.168.x.x:4300
- 192.168.x.y:4300
- 192.168.x.z:4300
1.9master高可用526行附近:
# We highly recommend to set the minimum master nodes as follows:
# minimum_master_nodes: (N / 2) + 1 where N is the cluster size
# That will ensure a full recovery of the cluster state.
discovery.zen.minimum_master_nodes: 2
要配置218行附近的
node.master: true
