中文 README

• Distributed: Can be scaled horizontally
• High performance: Allocation ID only accesses memory (up to the upper limit will request the database once)
• Ease of use: Provide as HTTP service
• Unique: MySQL auto increment ID, never repeat

We are using these awesome projects as necessary libraries.

• gopkg.in/yaml.v2
• github.com/go-sql-driver/mysql
• github.com/satori/go.uuid

You can install this service in the following three ways.

Note: You need to create the database and modify the configuration of the database in the configuration file before starting.

go get:

go get github.com/qichengzx/seqsvr
seqsvr

Compile By Yourself:

git clone [email protected]:qichengzx/seqsvr.git
cd seqsvr
go build .
./seqsvr

Docker:

The Docker "multi-stage" build feature is used, be ensure the Docker version is 17.05 or above. See:Use multi-stage builds

git clone [email protected]:qichengzx/seqsvr.git
cd seqsvr
docker build seqsvr:latest .
docker run -p 8000:8000 seqsvr:latest

The database name can be customized, modify config.yml.

Then import the following SQL to generate the data table.

CREATE TABLE `generator_table` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `uuid` char(36) NOT NULL COMMENT 'Machine identification',
  PRIMARY KEY (`id`),
  UNIQUE KEY `id_UNIQUE` (`id`),
  UNIQUE KEY `stub_UNIQUE` (`uuid`) USING BTREE
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

The configuration file is using YAML.
