AWS Notes
|
|
---------
|
|
|
|
### S3 Bucket
|
|
|
|
- Bucket *must* be named per the domain, eg. `trumped.com` instead of `trumped-index`.
|
|
- Static website hosting: set index.html, error.html
|
|
- Set the Bucket Policy: ```{
|
|
"Version": "2012-10-17",
|
|
"Id": "Policy1535378813796",
|
|
"Statement": [
|
|
{
|
|
"Sid": "Stmt1478413958263",
|
|
"Effect": "Allow",
|
|
"Principal": {
|
|
"AWS": "arn:aws:iam::961528074194:user/junglehorse"
|
|
},
|
|
"Action": "s3:*",
|
|
"Resource": "arn:aws:s3:::trumped.com/*"
|
|
},
|
|
{
|
|
"Sid": "PublicReadGetObject",
|
|
"Effect": "Allow",
|
|
"Principal": "*",
|
|
"Action": "s3:GetObject",
|
|
"Resource": "arn:aws:s3:::trumped.com/*"
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
- Set CORS headers,
|
|
|
|
```xml
|
|
<?xml version="1.0" encoding="UTF-8"?>
|
|
<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
|
|
<CORSRule>
|
|
<AllowedOrigin>*</AllowedOrigin>
|
|
<AllowedMethod>GET</AllowedMethod>
|
|
<AllowedMethod>HEAD</AllowedMethod>
|
|
<MaxAgeSeconds>3000</MaxAgeSeconds>
|
|
<AllowedHeader>*</AllowedHeader>
|
|
</CORSRule>
|
|
</CORSConfiguration>
|
|
```
|
|
|
|
- Note that the URL is `http://trumped.com.s3-website-us-east-1.amazonaws.com/` (static websites),
|
|
not `http://trumped.com.s3.amazonaws.com/` (REST endpoints)!
|
|
|
|
### Cloudfront
|
|
|
|
- Origin domain name: trumped-frontend.s3.amazonaws.com
|
|
- Origin path: (null)
|
|
- Origin id: S3-trumped-frontend
|
|
- Restrict access: no
|
|
- Alternative domain names (CNAMEs): trumped.com, www.trumped.com, cdn.trumped.com
|
|
- SSL certificate: Default Cloudfront (\*.cloudfront.net)
|
|
- Default root object: index.html
|
|
- Extra:
|
|
- Behaviors: `/` at precedence 0, forward query strings.
|
|
- Error pages (403, 404) to direct to `/error.html`
|
|
|
|
### Elastic Beanstalk
|
|
|
|
- (Make sure you're in the same region you set the app up in!)
|
|
- https://us-west-2.console.aws.amazon.com/elasticbeanstalk/home?region=us-west-2#/environment/dashboard?applicationName=junglehorse-api&environmentId=e-bgpvm79qkt
|
|
|
|
Running the server
|
|
------------------
|
|
|
|
### Locally
|
|
|
|
1. Install Rust >= 1.1.0
|
|
2. `cargo run`
|
|
|
|
### On the Remote Dedicated Server (non-AWS)
|
|
|
|
1. Install and configure nginx as a reverse HTTP proxy.
|
|
2. SCP Rust server app binaries and start on required ports, ie.
|
|
`trumpet -p PORT`.
|
|
|
|
Before moving to AWS, the DNS A records pointed to `209.239.112.74`,
|
|
which is the hostname `colossus960.startdedicated.com`.
|
|
|
|
### On AWS Infrastructure.
|
|
|
|
1. The frontend is hosted on AWS + Cloudfront.
|
|
2. The backend is hosted on Elastic Beanstalk (EBS).
|
|
|
|
The AWS setup is divided into two buckets: one that houses simply index.html,
|
|
which is hosted from `jungle.horse`. The other assets are distributed via
|
|
Cloudfront, and are loaded from `cdn.jungle.horse`. There is some CORS header
|
|
setup work to do. (See the s3-cors and s3-bucket files for config.)
|
|
|
|
The backend is a docker image containing the compiled Rust binary, config file,
|
|
and sound files. It can be built into a zip with the `./ebs-deployable` script.
|
|
This is then uploaded via the EBS panel's front page (the "Upload and Deploy"
|
|
button). This is hosted from `api.jungle.horse`.
|
|
|
|
Docker Notes
|
|
------------
|
|
Some notes for local management and testing of Docker images:
|
|
|
|
Build docker image from Dockerfile (in same working directory):
|
|
|
|
`sudo docker build -t TAGNAME .`
|
|
|
|
Run docker image interactively with port forwarding to host machine:
|
|
|
|
`sudo docker run -t -p 8000:8000 -i TAGNAME /bin/bash`
|
|
|
|
Misc Notes on Speech
|
|
--------------------
|
|
|
|
### Phonemes
|
|
|
|
- [CMU Dictionary](http://svn.code.sf.net/p/cmusphinx/code/trunk/cmudict/),
|
|
which uses [Arpabet](https://en.wikipedia.org/wiki/Arpabet).
|
|
- 54 units in the Arpabet:
|
|
- Vowels:
|
|
- 10 monophthongs (AO, AA, IY, UW, EH, IH, UH, AH, AX, AE)
|
|
- 5 diphthongs (EY, AY, OW, AW, OY)
|
|
- 8 R-colored vowels (ER, AXR, EH R, UH R, AO R, AA R, IH|IY R, AW R)
|
|
- Consonants:
|
|
- 6 Stops (P, B, T, D, K, G)
|
|
- 2 Affricates (CH, JH)
|
|
- 9 Fricatives (F, V, TH, DH, S, Z, SH, ZH, HH)
|
|
- 6 Nasals (M, EM, N, EN, NG, ENG)
|
|
- 5 Liquids (L, EL, R, DX, MX)
|
|
- 3 Semivowels (Y, W, Q)
|
|
|
|
### Diphones
|
|
|
|
TODO: Generate a list of phoneme 2-tuples.
|
|
|
|
### Unit Selection
|
|
|
|
- Combine multiple sources into final output (words, phonemes, diphones)
|
|
- Have alternatives (words, phonemes) that pair better with others.
|
|
- Optimize joining on a score (start/ending pitch, tempo, etc.)
|
|
|
|
Production Server
|
|
-----------------
|
|
The production server is `209.239.112.74`.
|
|
|
|
I'm using nginx as a reverse HTTP proxy.
|
|
|
|
To manage the process, `sudo service nginx restart`, etc.
|
|
|
|
To see what processes bind a port, `sudo lsof -i:80`, etc.
|
|
|
|
### Current nginx config
|
|
|
|
In sites-available, at `/etc/nginx/sites-enabled/default`,
|
|
|
|
```
|
|
server {
|
|
# XXX: Note - port 9000 is a temporary artifact; normally port 80.
|
|
listen 9000;
|
|
server_name jungle.horse;
|
|
location / {
|
|
proxy_pass http://127.0.0.1:8888;
|
|
}
|
|
}
|
|
|
|
server {
|
|
listen 9000;
|
|
server_name capitalism.store;
|
|
location / {
|
|
proxy_pass http://127.0.0.1:9999;
|
|
}
|
|
}
|
|
```
|
|
|
|
### Old IPTABLES Config
|
|
|
|
This was the old iptables-based routing. Even after flushing the rules,
|
|
port 80 still forwards to 9000 for some reason.
|
|
|
|
The rules were (prior to flush),
|
|
|
|
```
|
|
bt@colossus960:~$ sudo iptables --list-rules
|
|
-P INPUT ACCEPT
|
|
-P FORWARD ACCEPT
|
|
-P OUTPUT ACCEPT
|
|
-A INPUT -i eth0 -p tcp -m tcp --dport 80 -j ACCEPT
|
|
-A INPUT -i eth0 -p tcp -m tcp --dport 9000 -j ACCEPT
|
|
```
|
|
|
|
And,
|
|
|
|
```
|
|
bt@colossus960:~$ sudo iptables -L
|
|
Chain INPUT (policy ACCEPT)
|
|
target prot opt source destination
|
|
ACCEPT tcp -- anywhere anywhere tcp dpt:http
|
|
ACCEPT tcp -- anywhere anywhere tcp dpt:9000
|
|
|
|
Chain FORWARD (policy ACCEPT)
|
|
target prot opt source destination
|
|
|
|
Chain OUTPUT (policy ACCEPT)
|
|
target prot opt source destination
|
|
```
|
|
|
|
### User Creation
|
|
|
|
1. sudo useradd $NAME
|
|
2. sudo mkdir /home/$NAME
|
|
3. (copy .bashrc, .profile, .bash\_logout to homedir)
|
|
4. (chown homedir to new user)
|
|
5. sudo chsh -s /bin/bash $NAME
|
|
6. sudo passwd $NAME
|
|
|
