项目名:实现集群服务器

技术栈

  • Json序列化和反序列化
  • muduo网络库开发
  • nginx源码编译安装和环境部署
  • nginx的tcp负载均衡(也叫反向代理)器配置
  • redis缓存服务器编程实践
  • 基于发布-订阅的服务器中间件redis消息队列编程实践
  • MySQL数据库编程
  • CMake构建编译环境
  • Github托管项目

通过这项目你学到(或者复习到)

  • linux cpp
  • Json数据协议
  • moduo库（这个是我学习这个的主要目的之一）
  • nginx服务器的使用（这个是我学习这个的主要目的之一）
  • mysql
  • cmake

实现功能

  • 客户端注册登录

  • 加好友,加群

  • 好友聊天

  • 群聊天

  • 其他,待添加…

编码环境

linux+vscode

json环境

使用一个第三节库：

https://github.com/nlohmann/json/releases/download/v3.6.1/json.hpp

整个库文件只有一个json.hpp组成，使用json和使用stl一样简单

请看testjson文件夹

muduo库+boost库

参考如下博客进行集成开发：

https://blog.csdn.net/QIANGWEIYUAN/article/details/89023980

请看testmuduo文件夹

本质：muduo本身就是epoll+多线程

MySql数据库

登录mysql：

mysql -u root -proot

查看mysql服务开启了没有？

在这里插入图片描述

mysql的服务器及开发包

sudo apt-get install mysql-server =》 安装最新版MySQL服务器
sudo apt-get install libmysqlclient-dev =》 安装开发包

库chat，表 allgroup friend groupuser offlinemessage user

nginx配置tcp负载均衡

nginx在1.9版本之前，只支持http协议web服务器的负载均衡，

从1.9版本开始以后，nginx开始支持tcp的长连接负载均衡，但是nginx默认并没有编译tcp负载均衡模块，编写它时，需要加入–with-stream参数来激活这个模块。

nginx编译加入–with-stream参数激活tcp负载均衡模块

nginx编译安装需要先安装pcre、openssl、zlib等库，也可以直接编译执行下面的configure命令，根
据错误提示信息，安装相应缺少的库。

下面的make命令会向系统路径拷贝文件，需要在root用户下执行
tony@tony-virtual-machine:~/package/nginx-1.12.2# ./configure --with-stream
tony@tony-virtual-machine:~/package/nginx-1.12.2# make && make install

编译完成后，默认安装在了/usr/local/nginx目录。
tony@tony-virtual-machine:~/package/nginx-1.12.2$ cd /usr/local/nginx/
tony@tony-virtual-machine:/usr/local/nginx$ ls
conf html logs sbin

可执行文件在sbin目录里面，配置文件在conf目录里面。

具体步骤可以看下面的内容:

(注:要想在nginx编译加入–with-stream参数激活tcp负载均衡模块,不能直接使用sudo apt-get install nginx,还需下载源码,比如1.12.2这个版本)

具体步骤:

./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre=<path> option.

nginx -s reload 重新加载配置文件启动

nginx -s stop 停止nginx服务

按照上面的步骤 , 配置好之后,你就可以启动服务器的6000端口和6002端口,

然后 , 客户端启动8000端口

参考博客

https://blog.csdn.net/qq_20513027/article/details/88758356

https://blog.csdn.net/QIANGWEIYUAN/article/details/89023980

遇到的问题

  1. reason: [json.exception.type_error.316] invalid UTF-8 byte at index 0: 0xB8
    Aborted (core dumped)

解决：

response["errmsg"] = "该用户已经登录,请重新输入新账号!";
改成:
response["errmsg"] = "The user has logged in, please enter a new account!";

说实话,一直没搞懂编码究竟怎么搞,服务器是一个编码,编译器又是另外一个编码,一个utf-7,一个是gb18030,不清楚如何平衡这两种编码.

  1. 然后 , redis是基于发布-订阅的消息队列

redis暂时可装可不装,加了只是如虎添翼 ,

我暂时还没有体验到redis的好处,仅仅只是会安装和使用了 , 这个项目暂时先这样 , 后续再进行相关拓展.

redis的安装:

https://blog.csdn.net/weixin_52668597/article/details/133522930

补充:

还有许多其他的消息队列系统可用，例如：

  1. RabbitMQ：一个基于AMQP（高级消息队列协议）的开源消息队列系统。
  2. Apache Kafka：一个高吞吐量、分布式的消息队列系统，用于处理实时数据流。
  3. ActiveMQ：一个Java消息代理，支持多种消息协议，如AMQP、STOMP、OpenWire等。
  4. ZeroMQ：一个快速、异步的消息库，用于构建分布式应用程序。

测试

{“msgid”:1,“id”:1,“password”:“123456”}

{“msgid”:1,“id”:2,“password”:“666666”}

{“msgid”:5,“id”:1,“from”:“zhangsan”,“to”:2,“msg”:“hello!”}

{“msgid”:5,“id”:2,“from”:“li si”,“to”:1,“msg”:“hi!”}

注册

{“msgid”:3,“name”:“li si”,“password”:“666666”}

联合查询:

select a.id,a.name,a.state from user a inner join friend b on b.friendid = a.id where b.userid = 1;
