Yes, and, in itself, erlang is a separate song, which can be difficult to find an approach :) ejabberd mailing lists are also half dead, and it’s problematic to consult with someone about possible problems on high-load, so a lot to learn with bitter experience. Personally, I came across only “rumors” that the significantly patched ejabberd is the basis of WhatsApp services. Unfortunately, there are very few examples of successful ejabberd installations online that work with tens of thousands of connected users. If you store data in mnesia, then the figure can easily reach 100 Gb or more, but it all depends on the number of users and the data in the database. But, in fact, you can connect to xmlrpc from anything.Īs for the consumed resources, for 100 thousand connected users, somewhere under 25-30 Gb of memory is required (this is when storing most data in mysql, i.e., purely for servicing connected clients). We, for example, manage roster, groups, vcard'ami and other things through special workers written in php. If you left the ejabberd_xmlrpc module active (which has been built into ejabberd since version 13), then commands to the jabber server can also be transmitted via XmlRPC. Mod_admin_extra greatly expands the list of commands that can be passed through ejabberdctl. If everything went fine, then going to the admin :5280/admin/nodes/ in Running Nodes will be both nodes. Mnesia:change_table_copy_type(schema, node(), disc_copies). We change the table saving scheme, exit and run: If all is well, then in the list of running db nodes you will have both nodes. We copy the file /var/lib/ejabberd/.erlang_cookie from the first node to the second and if there are no problems with the connections between the nodes, then we assemble the cluster:Įrl -sname -mnesia dir '"/var/lib/ejabberd/"' -mnesia extra_db_nodes -s mnesia To create a cluster, take another server and perform the procedures described above.įor replication between nodes to work correctly (and indeed to assemble a cluster), it is necessary that the nodes can connect to each other on port 4369 and those ports that you specified in FIREWALL_WINDOW.
Configure ejabberd password#
Tab is important in yaml-configuration files, the Habr editor ate it from me, so be careful! I will dwell only on some parameters:Įjabberdctl.cfg (the parameters are individual, but I quote the ones that are registered we go to the mysql server, create a database there and fill it with a dump from mysql.sql from the sql folder of the ejabberd sources.Įjabberdctl register admin password The main configuration file ejabberd.yml is replete with examples and comments of developers, so it’s not difficult to configure it. ebin/mod_admin_extra.beam /usr/local/lib/ejabberd/ebin/ We compile mod_admin_extra to expand the list of available commands in ejabberdctl and via xmlrpc:Ĭd /usr/local/src/ejabberd-contrib/mod_admin_extraĬp.
Configure ejabberd install#
configure -enable-mysql=yes -enable-odbc=yes -enable-lager=yes -prefix=/usr/local -localstatedir=/var -enable-user=ejabberdĪssemble and install ejabberd: During the assembly of erlang and ejabberd, various nuances can arise, otherwise you will need to create a number of symlinks from / usr / local / lib | include in / usr / lib | include or “play around” with LDFLAGS / CPPFLAGS. Git clone git:///gamenet/ejabberd-contrib.gitĬreate an ejabberd user, specify / var / lib / ejabberd as the home directory.
Configure ejabberd download#
Next, download ejabberd and ejabberd-contrib: configure -prefix=/usr/local -enable-kernel-poll -with-ssl -enable-threads -with-odbc -enable-smp-support

(+ все что вам нужно)ĭownload the latest version of Erlang (at the time of writing article 17.2.2): Build Pkg install git fop libyaml wget unixODBC-2.3.2 expat wx30-gtk2 php5. Set prerequisites (git, fop, libyaml, wget, unixODBC, expat, wx30-gtk2, php5, etc): We also use an external authorization script in php, so php is also needed. I don’t see any reason to stop on installing the system, so under the cut, we’ll immediately proceed to the configuration.Įjabberd will store some of its data in mysql, so the odbc libraries must be installed on the system. In our case, FreeBSD was chosen as the system, since it is required to support a fairly large number of connections per node (~ 100k).

The new ejabberd has divided into two branches - ejabberd Community Server and ejabberd Business Edition and has begun to develop quite actively. Process One decided to change the versioning scheme for several reasons and version 2.x is now considered obsolete. A small preface: not so long ago the 13th was released, and this year the 14th version of ejabberd is also following it.
