 * SST is the full copy of data from one node to another. It's used when a new node joins the cluster, it has to transfer data from existing node. There are three methods of SST available in Percona XtraDB Cluster: :program:`mysqldump`, :program:`rsync` and :program:`xtrabackup` (Percona |XtraBackup| with support of XtraDB Cluster will be released soon, currently you need to use our `source code repository <http://www.percona.com/doc/percona-xtrabackup/installation/compiling_xtrabackup.html>`_). The downside of `mysqldump` and `rsync` is that your cluster becomes *READ-ONLY* while data is being copied from one node to another (SST applies :command:`FLUSH TABLES WITH READ LOCK` command). Xtrabackup SST does not require :command:`READ LOCK` for the entire syncing process, only for syncing |.FRM| files (the same as with regular backup).
 
-* Even with that, SST may be intrusive, that’s why there is IST mechanism.

Each node contains a cache, ring-buffer, (the size is configurable) of last N changes, and the node is able to transfer part of this cache.

+=====================================================
+ Setting up PXC reference architecture with HAProxy
+=====================================================
+
+This tutorial is a step-by-step guide to set up *Percona XtraDB Cluster*, in a virtualized test sandbox. This example uses Amazon EC2 micro instances, but the content here is applicable for any kind of virtualization technology (for example VirtualBox).
+You will need 4 virtual machines. 3 for |PXC| and 1 for the client, which will have |HAProxy|. In this how-to CentOS 6 is used as the operating system, the instructions are similar for any Linux distribution.
+
+The client node will have HAProxy installed and it will redirect requests to |PXC| nodes. This approach works well in real-world scenarios too. Running HAProxy on the application servers instead of having them as dedicated entities gives you benefits like no need for an extra network roundtrip, because loadbalancer and scalability of |PXC|'s load balancing layer scales simply with application servers.
+
+We'll use `Percona <http://www.percona.com/docs/wiki/repositories:yum>`_ and `EPEL <http://fedoraproject.org/wiki/EPEL>`_ repositories for software installation.
+
+After configuring the repositories you'll be able to install software that will be used. First, install |PXC| on the database nodes. ::
+
+  # yum -y install Percona-XtraDB-Cluster-server Percona-XtraDB-Cluster-client percona-xtrabackup
+
+Install |HAProxy| and |sysbench| on the client node. ::
+
+  # yum -y install haproxy sysbench
+
+After installing everything, we'll configure |PXC| first. On the first node, :file:`my.cnf` should look something like this on a relatively weak machine. ::
+
+  [mysqld]
+  server_id=1
+  binlog_format=ROW
+  log_bin=mysql-bin
+  wsrep_cluster_address=gcomm://
+  wsrep_provider=/usr/lib/libgalera_smm.so
+  datadir=/var/lib/mysql
+
+  wsrep_slave_threads=2
+  wsrep_cluster_name=pxctest
+  wsrep_sst_method=xtrabackup
+  wsrep_node_name=ip-10-112-39-98
+
+  log_slave_updates
+
+  innodb_locks_unsafe_for_binlog=1
+  innodb_autoinc_lock_mode=2
+  innodb_buffer_pool_size=400M
+  innodb_log_file_size=64M
+
+You can start your first node now. Make sure that you only start second and third nodes when the first node is up and running (it will serve as a donor for |SST|).
+
+This configuration is for the first node. For the second and third node, you need to change :option:`wsrep_cluster_address` (alternatively, you can use :option:`wsrep_urls` in [mysqld_safe] section), which should point to a node in the cluster which is already up, so it will join the cluster. The :option:`server_id` and :option:`wsrep_node_name` variables have to be different on each host, for :option:`wsrep_node_name`, you can use the output of `hostname` command.
+
+Based on that, for the second node, the differences in the configuration should be the following. :: 
+
+  server_id=2
+  wsrep_cluster_address=gcomm://10.116.39.76 # replace this with the IP of your first node
+  wsrep_node_name=ip-10-244-33-92
+
+For the third node, the differences look like this. ::
+
+  server_id=3
+  wsrep_cluster_address=gcomm://10.116.39.76 # replace this with the IP of your first node
+  wsrep_node_name=ip-10-194-10-179
+
+For |SST| we use |xtrabackup|. This means at startup time, the new node will connect to an existing node in the cluster and it takes a backup of that node with xtrabackup and copies it to the new node with `netcat`. After a successful |SST|, you should see this in the error log. ::

+
+When all nodes are started, you can set up HAProxy on the client. The point of this is that the application will be able to connect to localhost as |MySQL| server, so although we are using |PXC|, the application will see this as a single MySQL server running on localhost.
+
+In order to achieve this, you'll need to configure HAProxy on the client node. There are 2 possible configurations here.
+First is configuring round robin, which means you will connect and write to all cluster nodes. This can be done, but because of optimistic locking at commit time, rollbacks can happen if you have conflicting writes. In the second configuration, you will configure HAProxy in a way that it writes only to one node, so the application doesn't have to be prepared about unexpected rollbacks. The first configuration is a good choice in most cases, not handling rollbacks is not healthy in a well behaving application anyway.
+
+HAProxy can be configured in the /etc/haproxy/haproxy.cfg and it should look like this. ::

+
+In this configuration, three frontend-backend pairs are defined. The stats pair is for |HAProxy| statistics page, and the others are for |PXC|. |MySQL| will be listening on ports 3306 and 3307. If you connect to port 3306, you'll connect to `pxc-onenode`, and you'll be only using one node at a time (to avoid rollbacks because of optimistic locking). If that node goes off-line, you'll start using an other one.
+However if you connect to port 3307, you'll be using all three nodes for reads and writes too. In this case  the `leastconn` load balancing method is used instead of round robin, which means you always connect to the backend with the least connections established.
+The statistics page is accessible on the client node with a browser pointed to `/haproxy/stats`, the stats auth parameter in the configuration has the credentials for that in plain text. You can also use this for monitoring purposes (the CSV version is good for trending and alerting).
+
+Here |MySQL| is checked via HTTP checks. |MySQL| won't serve these requests. As part of |PXC| packages, we distribute the clustercheck utility which has to be set up. After that, HAProxy will be able to use check |MySQL| via HTTP. The clustercheck script is a simple shell script, which accepts HTTP requests, and checks MySQL on incoming request. If the |PXC| node is ok, it will emit a response with HTTP code 200 OK, otherwise, it emits 503. The script examines :option:`wsrep_local_state` variable.
+
+To set it up, create the clustercheck user. 
+
+.. code-block:: mysql
+
+  mysql> grant process on *.* to 'clustercheckuser'@'localhost' identified by 'clustercheckpassword!';
+  Query OK, 0 rows affected (0.00 sec)
+
+  mysql> flush privileges;
+  Query OK, 0 rows affected (0.00 sec)
+
+If you want to use a different username or password, you have to modify them in the script too.
+Let's test. :: 
+
+  # clustercheck
+  HTTP/1.1 200 OK
+
+  Content-Type: Content-Type: text/plain
+
+Node is running.
+
+You can use `xinetd` to daemonize the script. If `xinetd` is not installed yet, you can install it with yum. :: 
+
+  # yum -y install xinetd
+
+The service itself should be configured in :file:`/etc/xinetd.d/mysqlchk`. :: 
+
+  # default: on
+  # description: mysqlchk
+  service mysqlchk
+  {
+  # this is a config for xinetd, place it in /etc/xinetd.d/
+    disable = no
+    flags = REUSE
+    socket_type = stream
+    port = 9200
+    wait = no
+    user = nobody
+    server = /usr/bin/clustercheck
+    log_on_failure += USERID
+    only_from = 0.0.0.0/0
+    # recommended to put the IPs that need
+    # to connect exclusively (security purposes)
+    per_source = UNLIMITED
+  }
+
+Also, you should add the new service to :file:`/etc/services`. ::
+
+  mysqlchk 9200/tcp # mysqlchk
+
+Clustercheck will now listen on port 9200 after xinetd restart, and |HAProxy| is ready to check |MySQL| via HTTP. ::
+
+  # service xinetd restart
+
+If you did everything right so far, the statistics page of |HAProxy| should look like this.
+
+.. image:: ../_static/pxc_haproxy_status_example.png
+
+
+Testing the cluster with sysbench
+=================================
+
+You can test the cluster using the `sysbench <https://launchpad.net/sysbench/>`_ (this example uses one from the EPEL repository). First, you need to create a database and a user for it.
+
+.. code-block:: mysql
+
+  mysql> create database sbtest;
+  Query OK, 1 row affected (0.01 sec)
+
+  mysql> grant all on sbtest.* to 'sbtest'@'%' identified by 'sbpass';
+  Query OK, 0 rows affected (0.00 sec)
+
+  mysql> flush privileges;
+  Query OK, 0 rows affected (0.00 sec)
+
+Populate the table with data for the benchmark. ::
+
+  # sysbench --test=oltp --db-driver=mysql --mysql-engine-trx=yes --mysql-table-engine=innodb --mysql-host=127.0.0.1 --mysql-port=3307 --mysql-user=sbtest --mysql-password=sbpass --oltp-table-size=10000 prepare
+
+You can now run the benchmark against the 3307 port. ::
+
+  # sysbench --test=oltp --db-driver=mysql --mysql-engine-trx=yes --mysql-table-engine=innodb --mysql-host=127.0.0.1 --mysql-port=3307 --mysql-user=sbtest --mysql-password=sbpass --oltp-table-size=10000 --num-threads=8 run
+
+.. image:: ../_static/pxc_haproxy_lb_leastconn.png
+
+This is the status of `pxc-back backend` while the |sysbench| above is running. If you look at Cur column under Session, you can see, that c1 has 2 threads connected, c2 and c3 has 3.
+
+If you run the same benchmark, but against the 3306 backend, |HAProxy| stats will show us that the all the threads are going to hit the c1 server. ::
+
+  # sysbench --test=oltp --db-driver=mysql --mysql-engine-trx=yes --mysql-table-engine=innodb --mysql-host=127.0.0.1 --mysql-port=3306 --mysql-user=sbtest --mysql-password=sbpass --oltp-table-size=10000 --num-threads=8 run
+
+.. image:: ../_static/pxc_haproxy_lb_active_backup.png
+
+This is the status of `pxc-onenode-back` while |sysbench| above is running. Here only c1 has 8 connected threads, c2 and c3 are acting as backup nodes.
+
+If you are using |HAProxy| for |MySQL| you can break the privilege system’s host part, because |MySQL| will think that the connections are always coming from the load balancer. You can work this around using T-Proxy patches and some `iptables` magic for the backwards connections. However in the setup described in this how-to this is not an issue, since each application server has it's own |HAProxy| instance, each application server connects to 127.0.0.1, so MySQL will see that connections are coming from the application servers. Just like in the normal case.

- * This script makes the Sphinx sidebar collapsible.

- * .sphinxsidebar contains .sphinxsidebarwrapper.  This script adds
- * in .sphixsidebar, after .sphinxsidebarwrapper, the #sidebarbutton
- * used to collapse and expand the sidebar.
- *
- * When the sidebar is collapsed the .sphinxsidebarwrapper is hidden
- * and the width of the sidebar and the margin-left of the document
- * are decreased. When the sidebar is expanded the opposite happens.
- * This script saves a per-browser/per-session cookie used to
- * remember the position of the sidebar among the pages.
- * Once the browser is closed the cookie is deleted and the position
- * reset to the default (expanded).
