zookeeper installation configuration

  • Download the installation package of zookeeper from the official website: zookeeper image download website recommended by the official website
  • Unzip the compressed package of zookeeper to the specified installation directory
  • Create new data and log folders in the zookeeper installation directory, and set the zoo in the conf directory_ sample. Cfg file, copy it and rename it zoo CFG, in zoo Configure ticktime, dataDir and datalogdir in CFG
# The number of milliseconds of each tick
# The number of ticks that the initial 
# synchronization phase can take
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
# the port at which the clients will connect
# the maximum number of client connections.
# increase this if you need to handle more clients
# Be sure to read the maintenance section of the 
# administrator guide before turning on autopurge.
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
# The number of snapshots to retain in dataDir
# Purge task interval in hours
# Set to "0" to disable auto purge feature

tickTime: This time is as Zookeeper The time interval between servers or between clients and servers to maintain heartbeat, that is, each tickTime Time will send a heartbeat.
initLimit: This configuration item is used to configure Zookeeper Accept client (the client mentioned here is not a user connection) Zookeeper The client of the server, but Zookeeper Connect to in the server cluster Leader of Follower The maximum number of heartbeat intervals that the server can tolerate when initializing a connection. When the time has exceeded 10 heartbeats (i.e tickTime)After length Zookeeper If the server has not received the return information from the client, it indicates that the client connection has failed. The total length of time is 5*2000=10 second
syncLimit: This configuration item ID Leader And Follower How many messages can be sent between, and how long can the request and response time exceed tickTime The total length of time is 2*2000=4 second
dataDir: As the name suggests Zookeeper The directory where data is saved. By default, Zookeeper Save the log file for writing data in this directory.
clientPort: This port is the client connection Zookeeper The port of the server, Zookeeper It will listen to this port and accept the access request of the client.

 | This is the configuration file for Maven. It can be specified at two levels:
 |  1. User Level. This settings.xml file provides configuration for a single user,
 |                 and is normally provided in ${user.home}/.m2/settings.xml.
 |                 NOTE: This location can be overridden with the CLI option:
 |                 -s /path/to/user/settings.xml
 |  2. Global Level. This settings.xml file provides configuration for all Maven
 |                 users on a machine (assuming they're all using the same Maven
 |                 installation). It's normally provided in
 |                 ${maven.home}/conf/settings.xml.
 |                 NOTE: This location can be overridden with the CLI option:
 |                 -gs /path/to/global/settings.xml
 | The sections in this sample file are intended to give you a running start at
 | getting the most out of your Maven installation. Where appropriate, the default
 | values (values used when the setting is not specified) are provided.
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
  <!-- localRepository
   | The path to the local repository maven will use to store artifacts.
   | Default: ${user.home}/.m2/repository
  <!-- interactiveMode
   | This will determine whether maven prompts you when it needs input. If set to false,
   | maven will use a sensible default value, perhaps based on some other setting, for
   | the parameter in question.
   | Default: true

  <!-- offline
   | Determines whether maven should attempt to connect to the network when executing a build.
   | This will have an effect on artifact downloads, artifact deployment, and others.
   | Default: false

  <!-- pluginGroups
   | This is a list of additional group identifiers that will be searched when resolving plugins by their prefix, i.e.
   | when invoking a command line like "mvn prefix:goal". Maven will automatically add the group identifiers
   | "org.apache.maven.plugins" and "org.codehaus.mojo" if these are not already contained in the list.
    <!-- pluginGroup
     | Specifies a further group identifier to use for plugin lookup.

  <!-- proxies
   | This is a list of proxies which can be used on this machine to connect to the network.
   | Unless otherwise specified (by system property or command-line switch), the first proxy
   | specification in this list marked as active will be used.
    <!-- proxy
     | Specification for one proxy, to be used in connecting to the network.

  <!-- servers
   | This is a list of authentication profiles, keyed by the server-id used within the system.
   | Authentication profiles can be used whenever maven must make a connection to a remote server.
    <!-- server
     | Specifies the authentication information to use when connecting to a particular server, identified by
     | a unique name within the system (referred to by the 'id' attribute below).
     | NOTE: You should either specify username/password OR privateKey/passphrase, since these pairings are
     |       used together.
    <!-- Another sample, using keys to authenticate.
      <passphrase>optional; leave empty if not used.</passphrase>

  <!-- mirrors
   | This is a list of mirrors to be used in downloading artifacts from remote repositories.
   | It works like this: a POM may declare a repository to use in resolving certain artifacts.
   | However, this repository may have problems with heavy traffic at times, so people have mirrored
   | it to several places.
   | That repository definition will have a unique id, so we can create a mirror reference for that
   | repository, to be used as an alternate download site. The mirror site will be the preferred
   | server for that repository.
    <!-- mirror
     | Specifies a repository mirror site to use instead of a given repository. The repository that
     | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
     | for inheritance and direct lookup purposes, and must be unique across the set of mirrors.
      <name>Human Readable Name for this Mirror.</name>
	  <!--  <mirror>
                        <name>Nexus aliyun</name>
        </mirror>  -->
        <name>Spring Framework Maven Milestone Repository</name>
      <name>aliyun maven</name>

  <!-- profiles
   | This is a list of profiles which can be activated in a variety of ways, and which can modify
   | the build process. Profiles provided in the settings.xml are intended to provide local machine-
   | specific paths and repository locations which allow the build to work in the local environment.
   | For example, if you have an integration testing plugin - like cactus - that needs to know where
   | your Tomcat instance is installed, you can provide a variable here such that the variable is
   | dereferenced during the build process to configure the cactus plugin.
   | As noted above, profiles can be activated in a variety of ways. One way - the activeProfiles
   | section of this document (settings.xml) - will be discussed later. Another way essentially
   | relies on the detection of a system property, either matching a particular value for the property,
   | or merely testing its existence. Profiles can also be activated by JDK version prefix, where a
   | value of '1.4' might activate a profile when the build is executed on a JDK version of '1.4.2_07'.
   | Finally, the list of active profiles can be specified directly from the command line.
   | NOTE: For profiles defined in the settings.xml, you are restricted to specifying only artifact
   |       repositories, plugin repositories, and free-form properties to be used as configuration
   |       variables for plugins in the POM.
    <!-- profile
     | Specifies a set of introductions to the build process, to be activated using one or more of the
     | mechanisms described above. For inheritance purposes, and to activate profiles via <activatedProfiles/>
     | or the command line, profiles have to have an ID that is unique.
     | An encouraged best practice for profile identification is to use a consistent naming convention
     | for profiles, such as 'env-dev', 'env-test', 'env-production', 'user-jdcasey', 'user-brett', etc.
     | This will make it more intuitive to understand what the set of introduced profiles is attempting
     | to accomplish, particularly when you only have a list of profile id's for debug.
     | This profile example uses the JDK version to trigger activation, and provides a JDK-specific repo.


          <name>Repository for JDK 1.4 builds</name>

     | Here is another profile, activated by the system property 'target-env' with a value of 'dev',
     | which provides a specific path to the Tomcat instance. To use this, your plugin configuration
     | might hypothetically look like:
     | ...
     | <plugin>
     |   <groupId>org.myco.myplugins</groupId>
     |   <artifactId>myplugin</artifactId>
     |   <configuration>
     |     <tomcatLocation>${tomcatPath}</tomcatLocation>
     |   </configuration>
     | </plugin>
     | ...
     | NOTE: If you just wanted to inject this configuration whenever someone set 'target-env' to
     |       anything, you could just leave off the <value/> inside the activation-property.



  <!-- activeProfiles
   | List of profiles that are active for all builds.
