在網(wǎng)上找了一大堆例子，最后簡(jiǎn)化一下把，一下會(huì)從安裝mysql開(kāi)始，與大家分享一下如何用go鏈接服務(wù)器上的mysql

我用的是ubuntu系統(tǒng)

1，安裝mysql：sudo apt-get install mysql-server （記住root的密碼假設(shè)密碼為root123）

2，進(jìn)入mysql：mysql -uroot -p 然后輸入密碼

3，創(chuàng)建一個(gè)數(shù)據(jù)庫(kù)：create database people;

4，給數(shù)據(jù)庫(kù)people添加用戶：GRANT ALL PRIVILEGES ON people.* TO peo@localhost IDENTIFIED BY "peo123";

5,調(diào)整數(shù)據(jù)庫(kù)配置以便于遠(yuǎn)程訪問(wèn)：GRANT ALL PRIVILEGES ON people.* TO peo@“%” IDENTIFIED BY "peo123"; 然后推出mysql執(zhí)行：sudo nano /etc/mysql/my.cnf

修改bind-address=127.0.0.1 到bind-address= 機(jī)器的IP（就是安裝mysql的機(jī)器的ip）

6，重啟mysql：sudo /etc/init.d/mysql restart

7,建表：首先進(jìn)入mysql：mysql -u peo -p

進(jìn)入數(shù)據(jù)庫(kù)下：use people

創(chuàng)建表：create table hello(age int, name varchar(10));

插入一條數(shù)據(jù)：insert into hello(age, name) values(19, "hello world");

至此數(shù)據(jù)庫(kù)方面的工作已經(jīng)做好，接下來(lái)是go語(yǔ)言了

8，首先下載mysql的驅(qū)動(dòng)包（應(yīng)該是這樣叫）執(zhí)行 go get github.com/go-sql-driver/mysql代碼會(huì)下載到你的gopath下（執(zhí)行export可以查看gopath）

接著就是下面的代碼了

package main

import "database/sql"

import _ "github.com/go-sql-driver/mysql"

import "encoding/json"

import "fmt"

type User struct {

Age int `json:"age"`

Name string `json:"name"`

}

func main() {

fmt.Println("start")

db, err := sql.Open("mysql", "peo:peo123@tcp(192.168.0.58:3306)/people?charset=utf8")

if err != nil {

panic(err)

}

rows, err := db.Query("select age,name from hello")

if err != nil {

panic(err)

}

defer rows.Close()

for rows.Next() {

user := &User{}

err = rows.Scan(&user.Age, &user.Name)

if err != nil {

painc(err)

}

b, _ := json.Marshal(user)

fmt.Println(string(b))

}

println("end")

}

至此結(jié)束
