some other handsome features, such as three mode of friend list, playing animations when a friend going online, chat message history, auto-replying chat message when chatting, etc. You can explore more amazing features by your own in Flamingo.
- Install cmake, makefile and gcc tools.
Flamingo server is based on linux OS as platform(CentOS 7.0 is highly recommended), and compilers that support C++ 11 is required because the server code is fully developping with C++ 11. So on linux OS, the version of gcc/g++ must be high than 4.7(4.8.5 is recommended). In addition, cmake and makefile tool is required, so you need to install them.
- install mysql
Flaming server uses mysql database to store user data. If your OS is CentOS 7.0, you need to install mariadb-server, mariadb-client and mariadb-devel. On other linux OS, you need to install mysql-server, mysql-client and mysql-devel.
The Flamingo chatserver will use mysql database. The default database is named "flamingo". The database name, login user account(including username, password, etc) is configured in the file flamingoserver/etc/chatserver.conf. You can change this configuration as you will.
When chatserver startups at first time, it will dectect whether the database you configured exist in mysql. If it does not exist, the chatserver will create it including creating its related tables. So you do not need to create the database and tables manually. However the SQL syntax of creating table differs a litle in different mysql version, some SQL of creating tables might failed in some mysql version, therefore under this condition, you have to create tables manually. We prepare these SQLs for you in the file flamingoserver/table.sql.
Flamingo server uses four database tables illustrated below:
| Table Name | Usage |
|---|---|
| t_user | store user accounts |
| t_user_relationship | store user relationship and group members info |
| t_chatmsg | store chatting message |
-
Enter flamingoserver/ directory, then type commands below:
cmake .If no error occurs, a Makefile file will generated. We use this Makefile to generate server executable programs in next step.
-
Execute commands below to generate executable programs: chatserver、fileserver、imgserver.
make
All servers usage illustrated below:
Server Name Usage chatserver for user registeration, logining and chatting, and other IM essential functionalities fileserver for offline files transferring when chatting and pc upgrading imgserver for user avatar downloading & uploading and sending chatting image chatserver、fileserver、imgserver are independent with each other. You can startup one of them in Linux shell or run in daemon mode. Use following commands to run them in daemon mode:
./chatserver -d ./fileserver -d ./imgserver -d
You can use lsof command to confirm that the specified ports are on listening state normally:
[zhangyl@localhost flamingoserver]$ lsof -i -Pn COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME chatserve 18540 zhangyl 19u IPv4 1129031 0t0 TCP *:20000 (LISTEN) chatserve 18540 zhangyl 27u IPv4 1129032 0t0 TCP *:8888 (LISTEN) chatserve 18540 zhangyl 35u IPv4 1129033 0t0 TCP *:12345 (LISTEN) fileserve 18552 zhangyl 25u IPv4 1130523 0t0 TCP *:20001 (LISTEN) imgserver 18562 zhangyl 25u IPv4 1131971 0t0 TCP *:20002 (LISTEN)
Port Number Owner Usage 20000 chatserver Chatting Port 8888 chatserver Port for monitoring chatserver's inner state, you can use telnet or nc command to connect to chatserver to retrieve some realtime status and information of chatserver 12345 chatserver Http service port for chatserver, chatserver both support long TCP and short http connections 20001 fileserver File transferring port 20002 imgserver Tranferring port for sent chat images or user avatars We can use Linux nc command to connect to the Port 8888 of chatserver in table above, in the form of nc -v ip port. The port argument here is 8888 and -v option makes nc command to display more detailed information. Here is the usage:
[zhangyl@localhost flamingoserver]$ nc -v 127.0.0.1 8888 Ncat: Version 6.40 ( http://nmap.org/ncat ) Ncat: Connected to 127.0.0.1:8888. 1. help-show help info 2. ul-show online user list 3. su-show userinfo specified by userid: su [userid] ul No user online. su please specify userid. help 1. help-show help info 2. ul-show online user list 3. su-show userinfo specified by userid: su [userid]When connected to chatserver with nc successfully, you can type any one of the commands in the given list. I hava just implemented three commands as examples, namely: help, ul, su. You can add more functional commands if you need.
Hint: The server code is not only an IM Server source, but also a powerfully network framework writting in C++ 11. You will be able to of benefit more from it if you explore it more.
All you need to do is just that open file Flamingo.sln in flamingoclient/ directory with Visual Studio 2019 and compile it . The solution includes three projects illstrated in the table below:：
Project Name Usage Flamingo The main executable program of Flamingo pc client. CatchScreen A tool to catch screen in chatting window. iUpdateAuto Unzipping downloading files when upgrades.
When compiling finished successfully, the executable programs will be located in directory flamingoclient\Bin. And the configuration file which contains configured lines is located in file flamingoclient\Bin\config\flamingo.ini. Run Flamingo.exe and have fun!
Use Android Studio to open the project in directory flamingoAndroid/ and build to generate flamingo.apk file. Install flamingo.apk to your mobiles. Server settings of Android version is on the logining Activity.
I am afraid that I can not maintain Flamingo in regular intervals because I am very busy with my own work. But I promise that I am going to maintain Flamingo continually.

flamingo IM是一款高性能、轻量级的开源即时通讯软件，目前包括服务器端、pc端、安卓端，微信版本和IOS版本目前正在开发中。
目前已经实现了如下功能（这里只列举网络相关的功能，其他客户端已经实现的功能不统计在列，请自行发现）：
- 注册
- 登录
- 查找好友、查找群
- 添加好友、添加群
- 好友列表、群列表、最近会话
- 单人聊天功能（包括发文字、表情、窗口抖动、离线文件）
- 群组功能（包括发文字、表情）
- 群发消息
- 修改密码
- 修改个人信息（自定义昵称、签名、个性头像等个人信息）
- 自动升级功能
- 断线重连
- 客户端还有很多细节功能，比如头像有三种显示模式、好友上线动画、聊天记录、聊天自动回复功能等，有兴趣的同学可以自己探索尝试一下吧，这里就不截图了。
- 安装cmake、makefile和gcc。
作系统是linux，推荐的版本是CentOS 7.0以上。服务器代码使用纯C++11开发，所以您的gcc/g++版本必须至少在4.7以上，推荐的版本是4.8.5。另外，使用cmake和makefile工具进行项目管理和编译，因此您需要安装cmake和makefile工具。
-
安装mysql。
使用的数据库是mysql，如果您使用的是CentOS 7.0及以上系统，需要安装mariadb-server、mariadb-client和mariadb-devel。如果您使用的是其他版本的linux系统，请安装mysql-server、mysql-client和mysql-devel。
聊天服务chatserver会使用到mysql，mysql的库名（默认库名叫flamingo）、登陆用户名和密码配置在flamingoserver/etc/chatserver.conf文件中。
首次启动聊天服务chatserver时，程序会自动检测是否存在flamingo这样的库，如果不存在则创建之，并检测相应的数据表是否存在，如果不存在则创建它们。所以，无需手动创建对应的库和表。当然，不排除由于不同的mysql版本对应的SQL语法有细微差别，可能建表会失败，这个时候你可能需要手动建表，建表语句在flamingoserver/table.sql中。flamingo目前使用的四个表分别是：
表名 用途说明 t_user 用户信息表 t_user_relationship 好友关系及群成员信息表 t_chatmsg 聊天记录表
-
进入flamingoserver目录，执行：
cmake .如果没有错误，会产生一个Makefile文件。
-
执行如下命令生成可执行文件：chatserver、fileserver、imgserver。
make
各个服务的作用如下：
服务名称 用途说明 chatserver 聊天服务，用于基本的用户注册、登陆、聊天功能。 fileserver 文件服务，用于聊天窗口中的离线文件的发送和客户端自动升级包的下载。 imgserver 图片服务，用于聊天中图片文件的发送与用户自定义头像的上传与下载。 chatserver、fileserver、imgserver这三个服务是相互独立的，可以直接在linux shell中单独启动，也可以以守护进程的形式启动，守护进程形式启动命令：
./chatserver -d ./fileserver -d ./imgserver -d
可以使用一下lsof命令查看端口是否处于正常侦听状态：
[zhangyl@localhost flamingoserver]$ lsof -i -Pn COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME chatserve 18540 zhangyl 19u IPv4 1129031 0t0 TCP *:20000 (LISTEN) chatserve 18540 zhangyl 27u IPv4 1129032 0t0 TCP *:8888 (LISTEN) chatserve 18540 zhangyl 35u IPv4 1129033 0t0 TCP *:12345 (LISTEN) fileserve 18552 zhangyl 25u IPv4 1130523 0t0 TCP *:20001 (LISTEN) imgserver 18562 zhangyl 25u IPv4 1131971 0t0 TCP *:20002 (LISTEN)
端口号 所属服务 用途说明 20000 chatserver 聊天端口 8888 chatserver 聊天服务的监控端口，可以使用telnet或nc命令远程连接至聊天服务去查看服务器的一些实时状态信息 12345 chatserver 聊天服务的http端口，聊天服务不仅支持长连接，也支持http短连接。 20001 fileserver 文件服务端口 20002 imgserver 图片服务端口 上表中的8888端口可以使用nc命令，使用方式： nc -v ip port去连接，其中port这里就是8888，-v选项是nc命令支持的选项，表示要求显示的信息丰富一点。示例：
[zhangyl@localhost flamingoserver]$ nc -v 127.0.0.1 8888 Ncat: Version 6.40 ( http://nmap.org/ncat ) Ncat: Connected to 127.0.0.1:8888. 1. help-show help info 2. ul-show online user list 3. su-show userinfo specified by userid: su [userid] ul No user online. su please specify userid. help 1. help-show help info 2. ul-show online user list 3. su-show userinfo specified by userid: su [userid]连接成功以后，你可以根据命令说明输入相应的命令来查看服务器的状态信息，目前只实现三个命令，即上面显示的help、ul、su，您可以继续增加更多的命令。
**提醒一下：**服务器代码不仅是一款即时通讯软件的服务器代码，同时也是一款通用的C++11服务器框架。
使用Visual Studio 2019打开flamingoclient/目录下的Flamingo.sln即可编译。这个解决方案包括三个工程项目，说明如下：
项目名称 项目说明 Flamingo.sln flamingo pc版主程序 CatchScreen flamingo聊天中用的抓屏程序，类似QQ截图。 iUpdateAuto 用户pc端自动升级的zip解压工具。
生成后的程序位于目录flamingoclient\Bin目录下，其中客户端与服务器的连接配置信息位于flamingoclient\Bin\config\flamingo.ini文件中，直接打开Flamingo.exe即可启动flamingo pc端。
用Android Studio打开**flamingoAndroid/**目录下的安卓工程，编译产生相应的flamingo.apk文件，安装至安卓手机即可使用。与服务器的连接设置，在安卓版本的登陆界面的服务器设置中。
