1：安裝redigo

go get github.com/garyburd/redigo/redis

2：連線redis(通過ip埠)

c, err := redis.Dial("tcp", "192.168.2.225:6379")
if err != nil {
    fmt.Println("connect to redis err", err.Error())
    return
}
defer c.Close()

3：命令執行

n,err := c.Do("SET","key","value")  //寫
result,err := redis.String(c.Do
 
("GET","key"))//讀

4：string型別常見操作

set(key, value)：給資料庫中名稱為key的string賦予值value
get(key)：返回資料庫中名稱為key的string的value
getset(key, value)：給名稱為key的string賦予上一次的value
mget(key1, key2,…, key N)：返回庫中多個string的value
setnx(key, value)：新增string，名稱為key，值為value
setex(key, time, value)：向庫中新增string，設定過期時間time
mset(key
 
 N, value N)：批量設定多個string的值
msetnx(key N, value N)：如果所有名稱為key i的string都不存在
incr(key)：名稱為key的string增1操作
incrby(key, integer)：名稱為key的string增加integer
decr(key)：名稱為key的string減1操作
decrby(key, integer)：名稱為key的string減少integer
append(key, value)：名稱為key的string的值附加value
substr(key, start, end)：返回名稱為key的string的value
 
的子串

5：示例
5.1：SET-GET示例
設定key-value(“myname”,”Alice”)

_,err = c.Do("set","myname","Alice")
if err != nil{
    fmt.Println("redis set failed",err.Error())
}
myname,err := redis.String(c.Do("GET","myname"))
if err!= nil{
    fmt.Println("redis get failed",err.Error())
}else{
    fmt.Println("GET myname",myname)
}

5.2：GETSET示例
呼叫GETSET時，返回的是key值原來的value值，呼叫之後，該值被修改為現有的值

mydb,err = redis.String(c.Do("GETSET","mydb","mysql"))
if err != nil{
    fmt.Println("getset failed",err.Error())
}
fmt.Println("get before",mydb)
mydb,err = redis.String(c.Do("get","mydb"))
if err == nil{
    fmt.Println("mydb:",mydb)
}

5.3：SETNX示例

_,err = c.Do("setnx","foo","bluegogo")
if err != nil{
    fmt.Println("setnx failed",err.Error())
}
foo,err := redis.String(c.Do("get","foo"))
if err == nil{
    fmt.Println("setnx value",foo)
}

5.4：MSETNX-MGET示例
MSETNX設定不存在的key的值，如果該值存在，則值不會修改

_,err=c.Do("msetnx","bike1","ofo","bike2","bluegogo","bike3","foo")
if err != nil{
    fmt.Println("setnx failed")
}
var tmpbike1 string
var tmpbike2 string
var tmpbike3 string
array,err =redis.Values( c.Do("MGET","bike1","bike2","bike3"))
if err != nil{
   fmt.Println("mget failed",err.Error())
}else{
if _,err=redis.Scan(array,&tmpbike1,&tmpbike2,&tmpbike3);err == nil{
    fmt.Println("mget :",tmpbike1,tmpbike2,tmpbike3)
 }
}

5.5：MSET-MGET示例

_,err=c.Do("mset","bike1","mongo","bike2","redis","bike3","memcached")
if err != nil{
    fmt.Println("mset error",err.Error())
}
array,err =redis.Values( c.Do("MGET","bike1","bike2","bike3"))
if err != nil{
    fmt.Println("mget failed",err.Error())
}else{
if _,err=redis.Scan(array,&tmpbike1,&tmpbike2,&tmpbike3);err== nil{
        fmt.Println("mget :",tmpbike1,tmpbike2,tmpbike3)
   }
 }

5.6：SETEX-SET（定時）示例

_,err = c.Do("setex","ofo",10,"xiaoming")
if err != nil{
    fmt.Println("setex failed ",err.Error())
}
ofo,err := redis.String(c.Do("get","ofo"))
if err == nil{
    fmt.Println("setex ofo",ofo)
}
time.Sleep(11 *time.Second)
ofo,err = redis.String(c.Do("get","ofo"))
if err == nil{
     fmt.Println("setex ofo",ofo)
 }else{
    fmt.Println("time out get nil")
}

_,err = c.Do("SET","myage",10,"EX","10")
if nil != err{
    fmt.Println("redis set failed",err.Error())
}   
isExist,err := redis.Bool(c.Do("EXISTS","myage"))
if err != nil{
    fmt.Println("error",err.Error())
}else{
    fmt.Println("exists or not ",isExist)
}
time.Sleep(11*time.Second)

}
isExist,err = redis.Bool(c.Do("EXISTS","myage"))

}
_,err=c.Do("INCR","myage")
if err != nil{
    fmt.Println("incr error",err.Error())
}
myage,err = redis.String(c.Do("GET","myage"))
if err == nil{
    fmt.Println("after myage incr 1",myage)
}
_,err=c.Do("INCRBY","myage",10)
if err != nil{
    fmt.Println("incrby error",err.Error())

 if err == nil{
     fmt.Println("after myage DECR 1",myage)
 }
_,err=c.Do("DECRBY","myage",10)
if err != nil{
     fmt.Println("incrby error",err.Error())
}
myage,err = redis.String(c.Do("GET","myage"))
if err == nil{
    fmt.Println("after myage DECR 10",myage)
}
