docker創建mysql容器，go語言使用

一、下載鏡像
docker pull mysql


二、創建容器
docker run --name=mysql -it -p 3306:3306 -e MYSQL_ROOT_PASSWORD=emc123123 -d mysql  
在後臺啓動mysql容器(--name指定了容器的名稱，方便之後進入容器的命令行，MYSQL_ROOT_PASSWORD=emc123123指定了mysql的root密碼，-d表示在後臺運行)


三、創建數據庫和表項
mysql -uroot -pemc123123
create database test;
show databases
use test;
CREATE TABLE `userinfo` (
`uid` INT(10) NOT NULL AUTO_INCREMENT,
`username` VARCHAR(64) NULL DEFAULT NULL,
`departname` VARCHAR(64) NULL DEFAULT NULL,
`created` DATE NULL DEFAULT NULL,
PRIMARY KEY (`uid`)
); 
CREATE TABLE `userdetail` (
`uid` INT(10) NOT NULL DEFAULT '0',
`intro` TEXT NULL,
`profile` TEXT NULL,
PRIMARY KEY (`uid`)
);


四、go語言訪問數據庫


package main


import (
_ "github.com/Go-SQL-Driver/mysql"
"database/sql"
"fmt"
//"time"
)


func main() {
db, err := sql.Open("mysql", "root:emc123123@tcp(192.168.191.150:3306)/test?charset=utf8")
checkErr(err)
//插入數據
stmt, err := db.Prepare("INSERT userinfo SET username=?,departname=?,created=?")
checkErr(err)
res, err := stmt.Exec("astaxie", "研發部門", "2012-12-09")
checkErr(err)
id, err := res.LastInsertId()
checkErr(err)
fmt.Println(id)
//更新數據
stmt, err = db.Prepare("update userinfo set username=? where uid=?")
checkErr(err)
res, err = stmt.Exec("astaxieupdate", id)
checkErr(err)
affect, err := res.RowsAffected()
checkErr(err)
fmt.Println(affect)
//查詢數據
rows, err := db.Query("SELECT * FROM userinfo")
checkErr(err)
for rows.Next() {
var uid int
var username string
var department string
var created string
err = rows.Scan(&uid, &username, &department, &created)
checkErr(err)
fmt.Println(uid)
fmt.Println(username)
fmt.Println(department)
fmt.Println(created)
}
//刪除數據
stmt, err = db.Prepare("delete from userinfo where uid=?")
checkErr(err)
res, err = stmt.Exec(id)
checkErr(err)
affect, err = res.RowsAffected()
checkErr(err)
fmt.Println(affect)
db.Close()
}
func checkErr(err error) {
if err != nil {
panic(err)
}
}
