GO redis 相關操做

在gopath 目錄下安裝 go get github.com/garyburd/redigo/redis

package main
import (
	"fmt"
	"github.com/garyburd/redigo/redis"
)

//定義一個全局連接池變量
var pool *redis.Pool

//在main函數以前執行
func init() {	
	pool = &redis.Pool{
		MaxIdle: 8, //最大空閒連接數
		MaxActive: 0, //最大連接數,0不限
		IdleTimeout: 100, //最大空閒是時間
		Dial: func() (redis.Conn, error) {
			return redis.Dial("tcp", "192.168.166.35:6379", redis.DialPassword("Wintel51971355"), redis.DialDatabase(14))
		},
	}
}

func main () {	
	conn,err := redis.Dial("tcp", "192.168.166.35:6379", redis.DialPassword("Wintel51971355"), redis.DialDatabase(14))
	defer conn.Close()
	if err != nil {
		fmt.Println("connect redis err", err)

	_, err = conn.Do("Set", "name", "test哈羅")

	fmt.Println("get res", name)

	conn.Do("HMSET", "testKey", "field1", "val1", "field2", "val2")

	//從鏈接池中取連接
	conn2 := pool.Get()
	conn2.Do("set", "test2", "123")
