But in production, you should run - ZooKeeper in replicated mode. A replicated group of servers in the same - application is called a <emphasis>quorum</emphasis>, and in replicated - mode, all servers in the quorum have copies of the same configuration - file.</para> - <note> - <para> - For replicated mode, a minimum of three servers are required, - and it is strongly recommended that you have an odd number of - servers. If you only have two servers, then you are in a - situation where if one of them fails, there are not enough - machines to form a majority quorum. Two servers is inherently - <emphasis role="bold">less</emphasis> - stable than a single server, because there are two single - points of failure. - </para> - </note> - <para> - The required - <emphasis role="bold">conf/zoo.cfg</emphasis> - file for replicated mode is similar to the one used in standalone - mode, but with a few differences. Here is an example: - </para> - -<programlisting> -tickTime=2000 -dataDir=/var/lib/zookeeper -clientPort=2181 -initLimit=5 -syncLimit=2 -server.1=zoo1:2888:3888 -server.2=zoo2:2888:3888 -server.3=zoo3:2888:3888 -</programlisting> - - <para>The new entry, <emphasis role="bold">initLimit</emphasis> is - timeouts ZooKeeper uses to limit the length of time the ZooKeeper - servers in quorum have to connect to a leader.

In this example, the timeout - for initLimit is 5 ticks at 2000 milleseconds a tick, or 10 - seconds.</para> - - <para>The entries of the form <emphasis>server.X</emphasis> list the - servers that make up the ZooKeeper service.

That file has the - contains the server number, in ASCII.</para> - - <para>Finally, note the two port numbers after each server - name: " 2888" and "3888". Peers use the former port to connect - to other peers. Such a connection is necessary so that peers - can communicate, for example, to agree upon the order of - updates. More specifically, a ZooKeeper server uses this port - to connect followers to the leader. When a new leader arises, a - follower opens a TCP connection to the leader using this - port. Because the default leader election also uses TCP, we - currently require another port for leader election. This is the - second port in the server entry. - </para> - - <note> - <para>If you want to test multiple servers on a single - machine, specify the servername - as <emphasis>localhost</emphasis> with unique quorum & - leader election ports (i.e. 2888:3888, 2889:3889, 2890:3890 in - the example above) for each server.X in that server's config - file. Of course separate <emphasis>dataDir</emphasis>s and - distinct <emphasis>clientPort</emphasis>s are also necessary - (in the above replicated example, running on a - single <emphasis>localhost</emphasis>, you would still have - three config files).</para> - <para>Please be aware that setting up multiple servers on a single - machine will not create any redundancy. If something were to - happen which caused the machine to die, all of the zookeeper - servers would be offline. Full redundancy requires that each - server have its own machine. It must be a completely separate - physical server. Multiple virtual machines on the same physical - host are still vulnerable to the complete failure of that host.</para> - </note> - </section> - - <section> - <title>Other Optimizations</title> - - <para>There are a couple of other configuration parameters that can - greatly increase performance:</para> - - <itemizedlist> - <listitem> - <para>To get low latencies on updates it is important to - have a dedicated transaction log directory.
