Setup a max server

A server can hold several max server instances. We will centralize all instances in a known folder with the server name {server_dns}. Use server domain name for this variable. Each instance will have the same name, that will be used trough all the process:

cd /var/{server_dns}
git clone [email protected]:UPCnet/maxserver {instance_name}
cd /var/{server_dns}/{instance_name}
/var/python/python2.7/bin/python bootstrap.py -c max-only.cfg

Edit /var/{server_dns}/{instance_name}/mongoauth.cfg and fill in the password for the admin user of cluster in use.

Edit customizeme.cfg and modify the following options, each in its correct section. The port index must be a 2 digits, zero-padded number, starting at 1, that will be added to 10000 to calculate the real port. Each instance must have a different port_index:

[max-config]

name = use_osiris = true compat_id = 2

[mongodb-config] cluster_enabled = true cluster_hosts = replica_set =

[rabbitmq-config] username = password =

[hosts] max = rabbitmq = oauth =

[ports] port_index =

[urls] # Override oauth url ONLY if server url doesn't match # pattern https://SERVER_NAME/DOMAIN oauth = https://${hosts:oauth}/${max-config:name}

Set the correct type of oauth server only if you are NOT using a osiris server:

[max-config]
use_osiris = false

then proceed to execute buildout:

./bin/buildout -c max-only.cfg

Create init script for the max instance, at /etc/init.d/max_{instance_name}. Use this snippet as a template. Circus port must be 14100 plus the {port_index} choosed:

#!/bin/sh
# chkconfig: - 85 15

WORKDIR=/var/{server_dns}/{instance_name}
CONFDIR=$WORKDIR/config
ENDPOINT={circus_endpoint}

case "$1" in
'start')
    $WORKDIR/bin/circusd $CONFDIR/circus.ini --daemon
;;
'stop')
    $WORKDIR/bin/circusctl --endpoint tcp://127.0.0.1:$ENDPOINT stop
    $WORKDIR/bin/circusctl --endpoint tcp://127.0.0.1:$ENDPOINT quit
;;
'restart')
    $WORKDIR/bin/circusctl --endpoint tcp://127.0.0.1:$ENDPOINT restart
;;
*)
echo "Usage: $0 { start | stop | restart }"
;;
esac
exit 0

Create nginx entry for max at /var/nginx/config/max-instances/{instance_name}.conf, by using this snippet as a template. {max_port} must be 1000 plus the {port_index} choosed:::

location = /{instance_name} {rewrite ^([^.]*[^/])$ $1/ permanent;}

location ~* ^/{instance_name}/stomp {
    proxy_set_header X-Virtual-Host-URI $scheme://max.upcnet.es/{instance_name};
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;
    rewrite ^/{instance_name}/(.*) /$1 break;
    proxy_pass    http://rabbitmq_web_stomp_server;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
 }

location ~* ^/{instance_name}/(?!contexts|people|activities|conversations|messages|admin|info).*$ {
    proxy_set_header X-Virtual-Host-URI $scheme://max.upcnet.es;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;
    rewrite ^/{instance_name}/(.*) /{instance_name}/$1 break;

    proxy_pass    http://max.upcnet.es:11000;
 }

location ~ ^/{instance_name}/(.*) {

    if ($request_method = 'OPTIONS') {

        # Tell client that this pre-flight info is valid for 20 days
        add_header 'Access-Control-Max-Age' 1728000;
        add_header 'Content-Type' 'text/plain charset=UTF-8';
        add_header 'Content-Length' 0;

        return 200;
    }

    proxy_set_header X-Virtual-Host-URI $scheme://max.upcnet.es/{instance_name};
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;
    rewrite ^/{instance_name}/(.*) /$1 break;

    proxy_pass   http://max.upcnet.es:{max_port};
}

Create circus entry for max at /var/nginx/config/circus-instances/{instance_name}.conf, by using this snippet as a template. {circus_nginx_port} must be 15000 plus the {port_index} choosed:

server {
   listen   {circus_nginx_port};
   server_name  localhost;

   location / {

         proxy_http_version 1.1;
         proxy_set_header Upgrade $http_upgrade;
         proxy_set_header Connection "upgrade";
         proxy_set_header Host $host:$server_port;
         proxy_set_header X-Real-IP $remote_addr;
         proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
         proxy_set_header X-Forwarded-Proto http;
         proxy_set_header X-Forwarded-Host $host:$server_port;
         proxy_pass http://localhost:{circus_httpd_endpoint};
         auth_basic            "Restricted";
         auth_basic_user_file  /var/nginx/config/circus.htpasswd;
    }
}

Setup init script and start max instance:

chmod +x /etc/init.d/max_{instance_name}
update-rc.d max_{instance_name} defaults
/etc/init.d/max{instance_name} start
