This document assumes you're on a recent Debian or Ubuntu (help needed for the doc on other distributions).
It's a work in progress and you're invited to come chat with other developers on Miaou before and while installing.
You probably already have them if you coded on that computer. Basically you'll need recent versions of gcc, git, Python, etc.
sudo apt-get install build-essential
sudo apt-get install git
sudo apt-get install tcl8.5
(this should probably be completed)
There are various valid ways to install them. Be sure to install a recent version of node (tested on node 22).
cargo install miaou-builder
You must install and start redis. There's no specific configuration to do for Miaou (it's preferable to configure redis to not save on disk, as we only use it as a session cache making it possible to restart miaou without the users noticing).
sudo apt-get install redis-server
There's several ways to start it. Here's the simplest one:
redis-server &
sudo pacman -S redis
sudo systemctl start redis # only start server for this session
sudo systemctl enable redis # will start server for every **future** session
You need to fetch the repository from github, either directly of after a fork.
For example if not forking:
git clone https://github.com/Canop/miaou.git
cd miaou
When you'll want to update Miaou later, you'll do
git pull origin
TODO: explain how to deal with tagged stable releases
npm install
To build the application, first set the env variable MIAOU_ROOT then run
miaou-builder all
[WIP]
Before to start configuring, copy the config-default.js file into config.js:
cp config-default.js config.js
Most of the configuration is simple and documented in the file itself. We'll see how to set-up the database access and the OAUth authentication later in this document.
A different aventure every time. Be sure to install at least version 12.
First create the DB and user, and grant the rights.
> sudo -iu postgres
[sudo] password for youruser:
postgres@yourcomputer:/home/youruser$ psql
psql (9.4.0)
Type "help" for help.
postgres=# create database miaou;
CREATE DATABASE
postgres=# create user miaou with password 'chooseanotherpwdplease';
CREATE ROLE
postgres=# grant all privileges on database "miaou" to miaou;
GRANT
postgres=# alter database miaou owner to miaou;
ALTER DATABASE
postgres=# SHOW hba_file;
hba_file
--------------------------------------
/etc/postgresql/9.4/main/pg_hba.conf
(1 row)
Now you must modify the pg_hba.conf file (whose location vary, hence the query) to allow a md5 authentication.
Add the following at the start of the list of authentication methods:
local all miaou md5
Then restart pg :
sudo /etc/init.d/postgresql restart
sudo pacman -S postgresql
sudo -iu postgres
# You are now connected as postgres user
initdb -D /var/lib/postgres/data
echo """local all miaou md5""" >> /var/lib/postgres/data/pg_hba.conf
echo """create database miaou;create user miaou with password 'chooseanotherpwdplease';grant all privileges on database "miaou" to miaou;""" | psql
exit
# You are not anymore connected as postgres user
sudo systemctl start postgresql.service
sudo systemctl enable postgresql.service
You'll need this shell every time you want to mess with the tables, or for the first installation. Here's how it's launched :
psql -U miaou -W miaou
(the command to quit psql is \q)
A solution is to copy-paste the content of /sql/postgres-creation.sql into the pg shell.
Alternatively you can run the script from the standard shell using
psql -U miaou -d miaou -a -f sql/postgres.creation.sql
Note that you won't have to update the tables yourself, Miaou takes care of this updating when the schema changes or when a plugin needs a specific table.
In the config.js file, set up the required configuration :
"database": {
database:"miaou",
user:"miaou",
password:"choose-another-password-please",
"url": "postgres://miaou:choose-another-password-please@localhost/miaou",
"native_pg": false
},
You need to set up at least one OAuth provider.
- Google: create an OAuth account on https://code.google.com/apis/console/ (Read Hints bellow)
- StackExchange: create an OAuth account on http://stackapps.com/apps/oauth/
- Github: create an OAuth account on https://github.com/settings/applications
To fill the relevant parts of the configuration config.js, look for that commented part:
// OAuth providers. Remove or comment the ones you don't want to use
Once found, put the relevant info.
oauth2: {
"google": { // create one at https://code.google.com/apis/console/
"clientID": "your client ID",
"clientSecret": "your client secret"
},
"stackexchange": { // create one at http://stackapps.com/apps/oauth/
"clientID": "your client ID",
"clientSecret": "your client secret"
},
"github": { // create one at https://github.com/settings/applications
"clientID": "your client ID",
"clientSecret": "your client secret"
},
"reddit": {
"clientID": "your client ID",
"clientSecret": "your client secret"
}
},
Note: The clientId for Google look like this
"clientID": "883537075919-amp1s8ddogixnidpmu1kttvvhllqv1qt.apps.googleusercontent.com853539085919-amp1s8dqogiqnidump1kttvvhllqv1qt.apps.googleusercontent.com"
And the client secret for Google like this below
"clientSecret": "ceMq7gk81IltKHZZJiUVtU4Z"
With Google at least the same account can be used both for your local tests and for the deployment on a public server. Don't forget to register the callback with address 127.0.0.1, not localhost.
For example with Google OAuth2, the registered callbacks used for the dystroy Miaou server are
http://127.0.0.1:8204/auth/google/callback
https://miaou.dystroy.org/auth/google/callback
The first one is for the local tests, the second one for the public server.
Hint: With Google as provider you now need to enable the Google+ API in the Google console developper (simply go to https://console.developers.google.com then look for "Google+" API in the Enable API menu).
Hint: OAuth providers often need a small delay before propagating the changes so you might have to wait a few minutes before it works.
Use the script:
./restart.sh
This makes it easy to share the 80 port with other applications and to let nginx serve static resources for better performances. It's also the recommended solution to serve Miaou in HTTPS.
Don't try to use another proxy than nginx unless you really know what you do and how to check websockets correctly pass trough.
Installation is done with
sudo apt-get install nginx
cd /etc/nginx/site-enabled
vim www.yourdomain.conf
Copy (and maybe complete) this:
server {
listen 80;
# remove the following lines if you don't want to serve miaou over https
listen 443 ssl;
if ($ssl_protocol = "") {
rewrite ^ https://$host$request_uri? permanent;
}
ssl_certificate some-path.crt;
ssl_certificate_key some-other-path.key;
root /var/www/miaou;
index index.html;
server_name www.yourdomain;
error_page 404 /404.html;
# a reverse proxy for miaou, apart static which can be directly served
# (assuming the deploy script copies the static directory in /var/www/miaou/static)
location / {
access_log off;
proxy_pass http://www.yourdomain:8204/;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}
location /static/ {
access_log off;
location ~* \.(jpg|jpeg|png|gif|ico)$ {
expires 60d;
}
}
location /socket.io/ {
access_log off;
proxy_pass http://www.yourdomain:8204/socket.io/;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}
}
Restart nginx:
service nginx restart
