基于 cowboy(Small, fast, modern HTTP server for Erlang/OTP) 的即时聊天后端服务，使用 "阿里云8核16G ecs.sn1ne.2xlarge主机（100万PPS）"压测，保持100万+TCP，90分钟以上，详细测试件测试文档
因为我是中国人，所以选择了木兰宽松许可证, 第2版
一些功能的设计思考权衡过程，请参考文档
力求基于“语义化版本控制的规范”(语义化版本 2.0.0)实施版本管理.
Strive to implement version management based on "Specification for Semantic version Control"(Semantic Versioning 2.0.0).
数据结构(./doc/postgresql/)开发中有变动，以第一个发布版为准；目前改成基于 PostgreSQL15 开发
There are changes in the data structure (./doc/postgresql/vsn0.1) under development. It is currently based on PostgreSQL15
-
Erlang/OTP 24 (Cowboy 2.11 requires Erlang/OTP 24.0 or greater.)
-
Erlang/OTP 25
-
数据库 PostgreSQL15
erl -name debug -setcookie imboy
net_adm:ping('imboy@api.docker.imboy.pub').
net_kernel:connect_node('imboy@api.docker.imboy.pub').
erl -name debug@127.0.0.1
auth:set_cookie('imboy'),net_adm:ping('imboy@127.0.0.1').
net_adm:names().
{ok,[{"imboy",55042},{"debug",60595}]}
按 Ctrl+G 出现user switch command
然后输入
r 'imboy@127.0.0.1'
按回车
在按 J 机器显示节点:
--> j
1 {shell,start,[init]}
2* {'imboy@127.0.0.1',shell,start,[]}
在 * 的就是默认的可连接节点，其中的1 行，就是你现在的master节点
按 c 就能连接
你如果要连接到第三节点的话，直接 输入 c 6 回车就行了。

IMBOYENV=prod make relup
For the purpose of this section, assume the initial release version was 1, and the new version is 2. The name of the release will be example.
Once all this is done, you can build the tarball for the release upgrade:
$ make relup
This will create an archive at the root directory of the release, $RELX_OUTPUT_DIR/example/example-2.tar.gz.
Move the archive to the correct location on the running node. From the release’s root directory:
$ mkdir releases/2/
$ mv path/to/example-2.tar.gz releases/2/
Finally, upgrade the release:
https://erlang.mk/guide/relx.html
make clean
git checkout afb81f8 && make clean && IMBOYENV=local make rel
git checkout -f dev
vim relxlocal.config
