Stand-alone
Binary
dev mode
consul agent -dev -ui
Docker
docker-compose up -d
Cluster
An example: a cluster of 3 servers with UI enable
click Github
check consul-server-node1.hcl, consul-server-node2.hcl, consul-server-node3.hcl for more details
你需要根据你的实际情况来修改consul-server-node{1,2,3}.hcl的文件内容, 文件的字段说明如下:
根据你的需要, 参阅官方文档配置文件, 根据你的实际需求来添加修改
- node_name: 节点名称
- bind_addr: 绑定地址, 一般是本机IP
- bootstrap_expect: 集群中server节点的数量, 一般是3,5,7等奇数数量
- retry_join: 集群中server节点的地址, 除了本机的地址, 其他server节点的地址都需要填写
- datacenter: 数据中心名称, 默认是
dc1 - data_dir: 数据存储目录
- log_file: 日志文件路径
- log_level: 日志级别, 一般是
INFO - ui_config: Web UI选项
- enabled: 是否启用Web UI, 默认是
true - content_path : Web UI的路径, 默认是
/ui/
- enabled: 是否启用Web UI, 默认是
- addresses: http和dns的监听地址
- ports: http和dns的监听端口, 默认是
8500
used:
- nohup: no hang up
- -config-file: config file path
- & : run in background
server node1:
nohup consul agent -config-file=/home/data/consul/consul.d/consul-server-node1.hcl &
server node2:
nohup consul agent -config-file=/home/data/consul/consul.d/consul-server-node2.hcl &
server node3:
nohup consul agent -config-file=/home/data/consul/consul.d/consul-server-node3.hcl &
OR
你可能更喜欢命令行的方式:
server node1:
consul agent -server -bootstrap-expect 3 -data-dir /tmp/consul -node=node_158 -bind=192.168.0.158 -rejoin -config-dir=/home/data/consul/consul.d/ -client 0.0.0.0
server node2:
consul agent -server -bootstrap-expect 3 -data-dir /tmp/consul -node=node_152 -bind=192.168.0.152 -rejoin -config-dir=/home/data/consul/consul.d/ -client 0.0.0.0
server node3:
consul agent -server -bootstrap-expect 3 -data-dir /tmp/consul -node=node_155 -bind=192.168.0.155 -rejoin -config-dir=/home/data/consul/consul.d/ -client 0.0.0.0
Docker
TODO, 与上面的cluster的docker-compose.yml类似, 只是需要修改
command的内容
Client
Golang
-
install package
go mod tidy -
run test
go run consul_test.go -
run main
go run main.go -
check consul visited link http://localhost:8080/health to check consul health if you can see the network status code is 200 then consul is ok
后言
后续可能会添加Kubernetes的安装方式, 与更多在golang应用上的使用
