SQL to MongoDB Mapping Chart¶

In addition to the charts that follow, you might want to consider the
Frequently Asked Questions section for a selection of common questions about MongoDB.

Executables¶

The following table presents the MySQL/Oracle executables and the
corresponding MongoDB executables.

왜 Docker를 사용해야하는가?

Why Should I Care (For Developers)

"나에게 Docker의 매력은 간단히 격리된 환경을 만들 수 있다는 것과, 그러한 환경을 재사용할 수 있다는 점이다."런타임 환경을 한 번 만들어 패키지로 만들면, 이 패키지를 다른 어떤 머신에서도 다시 사용할 수 있다. 또한 여기서 실행되는 모든 것은 마치 가상머신과 같이 호스트로부터 격리되어있다. 무엇보다도 이런 모든 일들이 빠르고 간단히 가능하다.


## digest.js

var crypto = require('crypto');

	this.username = username;
	this.password = password;
	this.use_https = use_https;
}

## basic_auth_nodejs_test.js
var http = require('http');

var server = http.createServer(function(req, res) {
        // console.log(req);   // debug dump the request

        // If they pass in a basic auth credential it'll be in a header called "Authorization" (note NodeJS lowercases the names of headers in its request object)

        var auth = req.headers['authorization'];  // auth is in base64(username:password)  so we need to decode the base64
        console.log("Authorization Header is: ", auth);

                My notes on setting up and configuring GenieACS.
              
          
    Config files to get GenieACS up and running on Debian Testing, complete with GUI, Nginx SSL proxy, and systemd services.
Following the documentation here for dependencies, here for initial setup, then the wiki here for Nginx and SSL, should get you most of the way there. After that, I had a lot of googling to do, the results of which you can find below.


Filename
Description


01-install.sh
The installation instructions and commands.


02-config.json
The genieacs services configuration.


03-openssl.cnf
The openssl certificate configuration.


04-.env
The environmental variables for genieacs-gui.

    AWS에서 docker를 쓸 때 high traffic server라면 이렇게 하는 것이 좋겠다. amazon linux를 쓴다고 하자.
ulimit

ulimit를 올려주어야 한다. /etc/security/limit.conf 에서 고쳐주어도 docker에는 적용되지 않는다.
limit.conf는 PAM을 통해서 로그인했을 때만 먹는 설정이라 그렇다.
docker로 띄운 process의 pid를 찾고 cat /proc/<pid>/limits를 실행해서 보면 적용되었는지 아닌지 확실하게 알 수 있다.
kernel에서 직접 그 프로세스에 어떤 ulimit이 적용되었는지 확인하는 방법이다.
그래서 /etc/sysconfig/docker 파일을 만들고 아래를 추가한다.
