Locust 压测 MySQL 需要使用 Python 编写自定义代码来执行 SQL 查询和插入操作,并在 Locust 中调用该代码进行压力测试。
以下是一个示例代码,其中使用了 PyMySQL 库来连接和查询 MySQL 数据库:
```
import pymysql
class MySQLClient:
def __init__(self, host, user, password, database):
self.host = host
self.user = user
self.password = password
self.database = database
self.conn = None
def connect(self):
self.conn = pymysql.connect(
host=self.host,
user=self.user,
password=self.password,
database=self.database
)
def disconnect(self):
if self.conn is not None:
self.conn.close()
def select(self):
with self.conn.cursor() as cur:
cur.execute("SELECT * FROM users")
rows = cur.fetchall()
return rows
def insert(self, name, email):
with self.conn.cursor() as cur:
cur.execute("INSERT INTO users (name, email) VALUES (%s, %s)", (name, email))
self.conn.commit()
# Example usage:
# client = MySQLClient("localhost", "root", "password", "test")
# client.connect()
# results = client.select()
# client.insert("test user", "test@example.com")
# client.disconnect()
```
在 Locust 中,我们可以将此代码集成为 Task,以便可以测试其性能。此处使用 HttpUser 来进行测试:
```
from locust import HttpUser, TaskSet, task
class MyUser(HttpUser):
@task
def mysql_select(self):
client = MySQLClient("localhost", "root", "password", "test")
client.connect()
results = client.select()
client.disconnect()
@task
def mysql_insert(self):
client = MySQLClient("localhost", "root", "password", "test")
client.connect()
client.insert("test user", "test@example.com")
client.disconnect()
```
通过运行此测试,我们可以看到在给定的时间内对 MySQL 数据库执行的查询和插入操作的性能指标。需要记住的是,这仅提供了基本的示例代码,实际上还需要根据具体需求编写更详细的测试用例。
