callmedba / consul_register

将数据库rds信息或数据库实例信息注册到consul

consul_register

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

2. 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"]"
