- 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.
