Mac 下载 Redis
Mac安装Redis,原来就是这么简单
Mac Redix 数据库打开
- brew services start redis
服务端
- redis-server
客户端
- redis-cli
导包
package mainimport ("fmt""github.com/gomodule/redigo/redis"
)
连接数据库
func main() {c, err := redis.Dial("tcp", "localhost:6379")if err != nil {fmt.Println("conn redis failed,err:%v", err)return}defer c.Close()
}
操作字符串
// 获取字符串
func getString(c redis.Conn) {res, err := redis.String(c.Do("Get", "username"))if err != nil {fmt.Println(err)return}fmt.Println(res)
}// 设置字符串
func setString(c redis.Conn) {_, err := c.Do("Set", "username", "jack")if err != nil {fmt.Println(err)return}
}// 批量设置字符串
func setStrings(c redis.Conn) {_, err := c.Do("MSet", "username", "jack", "phone", "188888888")if err != nil {fmt.Println("MSet error:", err)return}
}// 批量获取字符串
func getStrings(c redis.Conn) {res2, err := redis.Strings(c.Do("MGet", "username", "phone"))if err != nil {fmt.Println("MGet error:", err)return}fmt.Println(res2)
}
操作 Hash
// redis Hash 操作 设置
func setHash(c redis.Conn) {_, err := c.Do("HSet", "names", "jim", "barry")if err != nil {fmt.Println("hset error: ", err)return}
}// redis Hash 操作 获取
func getHash(c redis.Conn) {res3, err := redis.String(c.Do("HGet", "names", "jim"))if err != nil {fmt.Println("hget error: ", err)return}fmt.Println(res3)
}
设置过期时间
// redis 设置过期时间
func setExpire(c redis.Conn) {_, err := c.Do("expire", "names", "10")if err != nil {fmt.Println("expire err: ", err)}
}
队列操作
// redis 队列
func queueOpr(c redis.Conn) {//入队列_, err := c.Do("lpush", "Queue", "jim", "barry", 9)if err != nil {fmt.Println("lpush error:", err)return}//出队列for true {r, err := redis.String(c.Do("lpop", "Queue"))if err != nil {fmt.Println("lpop error: ", err)return}fmt.Println(r)}//获取队列长度res4, err := redis.Int(c.Do("llen", "Queue"))if err != nil {fmt.Println("llen error: ", err)return}fmt.Println(res4)
}
连接池
// 使用 Pool 初始化连接池
var pool *redis.Poolfunc init() {pool = &redis.Pool{MaxActive: 1024,MaxIdle: 16,IdleTimeout: 300,Dial: func() (redis.Conn, error) {return redis.Dial("tcp", "localhost:6379")},}
}func main() {c := pool.Get()defer c.Close()_, err := c.Do("Set", "username", "jack")if err != nil {fmt.Println(err)return}r, err := redis.String(c.Do("Get", "username"))if err != nil {fmt.Println(err)return}fmt.Println(r)
}
并发操作
//redis并发实例
func main() {conn, err := redis.Dial("tcp", "localhost:6379")if err != nil {fmt.Println("connect redis error:", err)return}defer conn.Close()conn.Send("HSET", "students", "name", "jim", "age", "19")conn.Send("HSET", "students", "score", "100")conn.Send("HSET", "students", "age")conn.Flush()res1, err := conn.Receive()fmt.Printf("Receive res1:%v \n", res1)res2, err := conn.Receive()fmt.Printf("Receive res2:%v \n", res2)res3, err := conn.Receive()fmt.Printf("Receive res3:%v \n", res3)
}
管道化操作
//redis管道化操作
func main() {c, err := redis.Dial("tcp", "localhost:6379")if err != nil {fmt.Println("conn redis failed,err:", err)return}defer c.Close()c.Send("SET", "username1", "jim")c.Send("SET", "username2", "jack")c.Flush()v, err := c.Receive()fmt.Printf("v:%v,err:%v\n", v, err)v, err = c.Receive()fmt.Printf("v:%v,err:%v\n", v, err)v, err = c.Receive()fmt.Printf("v:%v,err:%v\n", v, err)
}
事务操作
// redis事务操作
func main() {conn, err := redis.Dial("tcp", "localhost:6379")if err != nil {fmt.Println("connect redis error:", err)return}defer conn.Close()conn.Send("MULTI")conn.Send("INCR", "Foo")conn.Send("INCR", "bar")r, err := conn.Do("EXEC")fmt.Println(r)
