Golang 实现的 mysql-proxy
Golang1.1昨天发布,性能提升不少。让我想起去年写的mysql-proxy,于是拿出来又改了一下调用最为频繁的一个函数,发现性能已经非常理想。这里放出来给有兴趣的朋友试用。 目前支持的功能是读写分离(非事务,如果用事务的话不会分发到slave上)和slave的负载
Golang1.1昨天发布,性能提升不少。让我想起去年写的mysql-proxy,于是拿出来又改了一下调用最为频繁的一个函数,发现性能已经非常理想。这里放出来给有兴趣的朋友试用。
目前支持的功能是读写分离(非事务,如果用事务的话不会分发到slave上)和slave的负载均衡,未做失效检查。另外prepare可能会有问题。
如果有什么需求可以后续添加,golang改起来非常方便,当初这个proxy我也就1个礼拜完成的。

(有需要win版本的可以密我)
配置:
1. 需要配置用于连接proxy的用户名和密码(sha1(plain password))
2. 需要配置连接后端master和slave的用户和密码(sha1(plain password))
3. slaves需要按照proxy.ini 格式写,因为解析ini文件的目前还没有容错
(本来是打算配置用web界面来做的,被其他事情给耽搁了)
启动:
目前启动方式很山寨
cd /path/to/proxy && ./proxy
(这个容易改,我已经有现成的python manager,套用过来就行)
大家有什么反馈可以q我或者这里留言(第一次需要审核,防止垃圾广告。)

Reading and writing files safely in Go is crucial. Guidelines include: Checking file permissions Closing files using defer Validating file paths Using context timeouts Following these guidelines ensures the security of your data and the robustness of your application.

How to configure connection pooling for Go database connections? Use the DB type in the database/sql package to create a database connection; set MaxOpenConns to control the maximum number of concurrent connections; set MaxIdleConns to set the maximum number of idle connections; set ConnMaxLifetime to control the maximum life cycle of the connection.

JSON data can be saved into a MySQL database by using the gjson library or the json.Unmarshal function. The gjson library provides convenience methods to parse JSON fields, and the json.Unmarshal function requires a target type pointer to unmarshal JSON data. Both methods require preparing SQL statements and performing insert operations to persist the data into the database.

The difference between the GoLang framework and the Go framework is reflected in the internal architecture and external features. The GoLang framework is based on the Go standard library and extends its functionality, while the Go framework consists of independent libraries to achieve specific purposes. The GoLang framework is more flexible and the Go framework is easier to use. The GoLang framework has a slight advantage in performance, and the Go framework is more scalable. Case: gin-gonic (Go framework) is used to build REST API, while Echo (GoLang framework) is used to build web applications.

The FindStringSubmatch function finds the first substring matched by a regular expression: the function returns a slice containing the matching substring, with the first element being the entire matched string and subsequent elements being individual substrings. Code example: regexp.FindStringSubmatch(text,pattern) returns a slice of matching substrings. Practical case: It can be used to match the domain name in the email address, for example: email:="user@example.com", pattern:=@([^\s]+)$ to get the domain name match[1].

Go framework development FAQ: Framework selection: Depends on application requirements and developer preferences, such as Gin (API), Echo (extensible), Beego (ORM), Iris (performance). Installation and use: Use the gomod command to install, import the framework and use it. Database interaction: Use ORM libraries, such as gorm, to establish database connections and operations. Authentication and authorization: Use session management and authentication middleware such as gin-contrib/sessions. Practical case: Use the Gin framework to build a simple blog API that provides POST, GET and other functions.

Using predefined time zones in Go includes the following steps: Import the "time" package. Load a specific time zone through the LoadLocation function. Use the loaded time zone in operations such as creating Time objects, parsing time strings, and performing date and time conversions. Compare dates using different time zones to illustrate the application of the predefined time zone feature.
