本文对consul的分布式集群部署做介绍，consul版本为1.x

环境

• linux系统（centos）
• 节点数：3

材料准备

1. consul_1.3.0.zip(官网下载)
2. acl.json

{
"acl_datacenter": "datacenter1",
"acl_master_token": "xxxx-xxxx-xxxx-xxxx-xxxx1",
"acl_default_policy": "deny",
"acl_down_policy": "extend-cache",
"acl_agent_token": "xxxx-xxxx-xxxx-xxxx-xxxx2"
}

安装部署

1. 在所有服务器上，解压部署包

unzip consul_1.3.0.zip -d consul_server

2. 部署包可执行赋权限

chmod 755 consul_server

3. 启动服务

export IP=$(shell ifconfig -a|grep inet| grep -v 127.0.0.1|grep -v inet6|awk `{print$$2}`|tr -d `addr`)
cd consul_server; nohup ./consul agent -server -bootstrap-expect 3 -pid-file consul.pid -data-dir ./data -config-dir conf.d -bind ${IP} -client 0.0.0.0 -ui -datacenter datacenter1 -rejoin &

4. 加入集群

在服务器1上执行：

cd consul_server; ./consul join ${IP2}
cd consul_server; ./consul join ${IP3}

5. 服务重启，使得acl配置生效

cd consul_server; kill -15 `cat consul.pid`
cd consul_server; nohup ./consul agent -server -bootstrap-expect 3 -pid-file consul.pid -data-dir ./data -config-dir conf.d -bind ${IP} -client 0.0.0.0 -ui -datacenter datacenter1 -rejoin &

6. 查看集群成员

cd consul_server; 
export CONSUL_HTTP_TOKEN='xxxx-xxxx-xxxx-xxxx-xxxx1'
./consul members

7. 创建新agent token

curl -X PUT -d '{"ID": "ID1", "Name": "agent1", "Type": "client", "Rules": "key\" \"polict=\"read\" key \"test_folder\" {policy=\"write\"}"}'

8. 验证（略）

curl -i -X PUT http://127.0.0.1:8500/v1/kv/test_folder/hello?token=xxxx-xxxx-xxxx-xxxx-xxxx2 -d test1
