这是一个简单的初始化缓存池

1.导入包

import "github.com/gomodule/redigo/redis"

2. 缓存池配置(推荐和Golang读取配置文件一起使learnku.com/articles/58…)

package setting

import (
	"fmt"
	"github.com/gomodule/redigo/redis"
	"log"
	"time"
)

var (
   RedisPool *redis.Pool
)

func InitRedisPool() {

	RedisPool = &redis.Pool{
		//最大闲置连接
		MaxIdle: 30,
		//最大活动数
		MaxActive: 30,
		//数据库连接
		Dial: func() (redis.Conn, error) {
			c, err := redis.Dial("tcp", "127.0.0.1:6379")
			if err != nil {
				c.Close()
				fmt.Printf("fail to dial redis: %v\n", err)
				return nil, err
			}
			//密码认证,可填入redisd的连接密码
			if _, err = c.Do("AUTH", ""); err != nil {
				c.Close()
				fmt.Printf("fail to auth redis: %v\n", err)
				return nil, err
			}

			//redis 缓存数据库认证
			if _, err = c.Do("SELECT", ""); err != nil {
				c.Close()
				fmt.Printf("fail to SELECT DB redis: %v\n", err)
				return nil, err
			}
			return c, err
		},
		//测试连接是否正常
		TestOnBorrow: func(c redis.Conn, t time.Time) error {
			_, err := c.Do("PING")
			if err != nil {
				c.Close()
				fmt.Printf("fail to ping redis: %v\n", err)
				return err
			}
			return nil
		},
	}
	log.Println("connect redis success")
}

func Get() redis.Conn {
	return RedisPool.Get()
}
