6 Jmeter 压测

1 查询商品 goods/to_list

1. 1000 * 10
   
   2 10000 * 1
   

3 10000 * 10

2 查询用户 user/info

3 csv config

user,userToken
19860207586,beee92446e3349bdb3b2321c5eed6d24

4 JMeter 命令行

• 在windows上录好jmx
• 命令行：sh jmeter.sh -n -t XXX.jmx -l result.jtl
• 把result.jtl 导入到jmeter

5 redis 压测

• [100个并发连接，100000个请求]

redis-benchmark -h 10.23.23.25 -p 6379 -c 100 -n 100000


# 或者
redis-benchmark -h 127.0.0.1 -p 6379 -c 100 -n 100000 

• 存取大小为100 字节的数据包

redis-benchmark -h 10.23.23.25 -p 6379 -q -d 100

报错:(base) gigabyte@gigabyte-X299-UD4-Pro:~$ redis-benchmark -h 127.0.0.1 -p 6379 -c 100 -n 100000
ERROR: NOAUTH Authentication required.
ERROR: failed to fetch CONFIG from 127.0.0.1:6379

分析： 应该是需要验证密码
解决：redis-benchmark -h
发现 -a

redis-benchmark -h 10.23.23.25 -p 6379 -c 100 -n 100000 -a 123

redis-benchmark -h 10.23.23.25 -p 6379 -q -d 100 -a 123

6 命令行下压测

• 1 先去启动后台程序

sudo nohup java -jar miaosha.jar  >> miaosha.out 2>&1 &

• 2 将jmeter上传至服务器
  
• 3 执行命令

 ./apache-jmeter-5.4.1/bin/jmeter.sh -n -t good_list.jmx -l result.jtl 

• 4 查看处理器
  cat /proc/cpu info | grep processor
  
• 5 下载result.jtl，放回jmeter中查看
  

7 生成user插入到数据库中

List<MiaoshaUser> users = new ArrayList<MiaoshaUser>(count);//生成用户for(int i=0;i<count;i++) {
   MiaoshaUser user = new MiaoshaUser();   user.setId(13000000000L+i);   user.setLoginCount(1);   user.setNickname("user"+i);   user.setRegisterDate(new Date());   user.setSalt("1a2b3c");   user.setPassword(MD5Util.inputPassToDbPass("123456", user.getSalt()));   users.add(user);}
System.out.println("create user");//插入数据库Connection conn = DBUtil.getConn();String sql = "insert into miaosha_user(login_count, nickname, register_date, salt, password, id)values(?,?,?,?,?,?)";PreparedStatement pstmt = conn.prepareStatement(sql);System.out.println("users.size(): " + users.size());for(int i=0;i<users.size();i++) {
   MiaoshaUser user = users.get(i);   pstmt.setInt(1, user.getLoginCount());   pstmt.setString(2, user.getNickname());   pstmt.setTimestamp(3, new Timestamp(user.getRegisterDate().getTime()));   pstmt.setString(4, user.getSalt());   pstmt.setString(5, user.getPassword());   pstmt.setLong(6, user.getId());   pstmt.addBatch();}
pstmt.executeBatch();pstmt.close();conn.close();System.out.println("insert to db");

8 登录，生成token

• 1 修改login/do_login

@RequestMapping("/do_login")
@ResponseBodypublic Result<Boolean> doLogin(HttpServletResponse response, @Valid LoginVo loginVo){
    log.info(loginVo.toString());    Boolean b = miaoshaUserService.login(response, loginVo);    return Result.success(true);}
# -- > 变成
@RequestMapping("/do_login")
@ResponseBodypublic Result<String> doLogin(HttpServletResponse response, @Valid LoginVo loginVo) {
    log.info(loginVo.toString());    //登录    String token = miaoshaUserService.login(response, loginVo);    return Result.success(token);}
# service 里
//        return true;        return token;

//登录，生成tokenString urlString = "http://10.23.23.25:8080/login/do_login";File file = new File("D:/tokens.txt");if(file.exists()) {
   file.delete();}
RandomAccessFile raf = new RandomAccessFile(file, "rw");file.createNewFile();raf.seek(0);for(int i=0;i<users.size();i++) {
   MiaoshaUser user = users.get(i);   URL url = new URL(urlString);   HttpURLConnection co = (HttpURLConnection)url.openConnection();   co.setRequestMethod("POST");   co.setDoOutput(true);   OutputStream out = co.getOutputStream();   String params = "mobile="+user.getId()+"&password="+MD5Util.inputPassFormPass("123456");   out.write(params.getBytes());   out.flush();   InputStream inputStream = co.getInputStream();   ByteArrayOutputStream bout = new ByteArrayOutputStream();   byte buff[] = new byte[1024];   int len = 0;   while((len = inputStream.read(buff)) >= 0) {
      bout.write(buff, 0 ,len);   }
   inputStream.close();   bout.close();   String response = new String(bout.toByteArray());   JSONObject jo = JSON.parseObject(response);   String token = jo.getString("data");   System.out.println("create token : " + user.getId());   String row = user.getId()+","+token;   raf.seek(raf.length());   raf.write(row.getBytes());   raf.write("\r\n".getBytes());   System.out.println("write to file : " + user.getId());}
raf.close();System.out.println("over.................");

9 jmeter上配置

修改miaosha.jmx文件

 ./apache-jmeter-5.4.1/bin/jmeter.sh -n -t miaosha.jmx -l miaosha_result.jtl
