Linux性能优化-SQL慢查询

 

 

安装环境

git 下载相关例子代码

git clone https://github.com/feiskyer/linux-perf-examples

案例由三个容器组成，一个MySql数据库应用，一个商品搜索应用，一个数据处理应用
其中商品搜索应用提供了HTTP借口
/，                                  返回Index Page
/db/insert/products/，    插入指定数据量的商品信息
/products/,                      查询指定商品的信息，并返回处理事件

案例的整体结构如下

运行并检查docker容器中的应用

make run
docker run --name=mysql -itd -p 10000:80 -m 800m feisky/mysql:5.6
