目前用来实现数据库信息注册到consul， 服务里定义好了注册模板，并且支持特定注册参数的修改
1、注册模板
模板举例：
s_id='' // 实例ID
s_name='db-mysql'
s_ip='rm-xxxxxxxxxxxxxx.mysql.rds.aliyuncs.com' //实例内网域名
s_port=3306
s_tcp='rm-xxxxxxxxxxxxxx.mysql.rds.aliyuncs.com:3306' //域名+端口
s_region='rds' //根据实例所在区来注册， 比如sh_idc, hz_idc ...
s_put="""
{
"ID": "$s_id",
"Name": "$s_name",
"Address": "$s_ip",
"Port": $s_port,
"Tags": ["$s_region"],
"Meta": {
"region": "$s_region",
"alias": "$s_id",
"ip": "$s_ip",
"service_type": "mysql-master", //根据rds 是主库还是从库，从库为mysql-slave
"service_detail": "杭州作为测试使用"
} ,
"Check": {
"Name": "$s_id",
"DeregisterCriticalServiceAfter": "1440m",
"TCP": "$s_tcp",
"Interval": "60s",
"Timeout": "5s"
}
}
"""
echo $s_put
curl http://consul地址/v1/agent/service/register -H 'Accept: application/json' -X PUT -d "$s_put"
2、注销模板
curl --request PUT http://consul地址/v1/agent/service/deregister/id
id 为要注销的rds 实例id
3、HTTP请求
目前ops运维平台的功能集成方式，为负责人开发相应功能， 运维开发集成http接口。
故consul的注册和注销功能也是服务化的， 服务采用go语言开发，端口暂时采用9160端口。
这里主要涉及到4个接口。
1）consul 地址和模板
curl -i http://127.0.0.1:9160/setConsulTemplate-H 'Accept: application/json' -X PUT -d "{"ConsulAddress":"http://consul地址\",\"ConsulTemplate\": {"Tags":["region","businessdfg","module"],"Check":{ "DeregisterCriticalServiceAfter":"1400m","Interval":"60s","Timeout": "5s" } }}"
Tags值为具体的tag列表
- 获取consul 模板
curl -i http://127.0.0.1:9160/getConsulTemplate-XGET
3）注册请求
curl -i http://127.0.0.1:9160/register -H 'Accept: application/json' -X PUT -d"["rm-xxxxxxx1","rm-xxxxxxx2"]"
4）注销请求
curl -i http://127.0.0.1:9160/deregister -H 'Accept: application/json' -X PUT -d "["rm-xxxxxxx1","rm-xxxxxxx2"]"
