# master-election
master-election是进行主从选举的工具包。在分布式场景，我们经常需要多个实例中的某一个实例去单独的运行某一串逻辑。
此包可以帮助你快速上手，并且忽略掉选主的具体细节。
### 支持组件
- Mysql (已完成)
- Redis (待开发)
- PostgreSQL (待开发)
- ETCD (待开发)
- Consul (待开发)
- Mongodb (待开发)
### 安装
````
go get github.com/changsongl/master-election

### 示例
```` go
package main
import (
"fmt"
"time"
"github.com/changsongl/master-election"
"github.com/changsongl/master-election/lock/mysql"
)
func main() {
m, err := master.New(
mysql.NewMasterLock(
&mysql.Config{
User: "root",
Password: "123456",
Host: "127.0.0.1",
Port: 3306,
TableName: "master_election_table",

},
),
master.OptionHeartbeat(time.Second*2),
master.OptionMasterStartHook(func(epoch uint64) {
fmt.Printf("master start: epoch %d\n", epoch)
}),
master.OptionMasterEndHook(func(epoch uint64) {
fmt.Printf("master end: epoch %d\n", epoch)
}),
// other option available
)
if err != nil {
panic(err)
}
go func() {
err = m.Start()
if err != nil {
panic(err)
}
}()
for {
if m.IsMaster() {
// do some master logic
} else {
// do some slave logic or do nothing
}
}
// m.Stop()
}
