databus 分为 relay bootstrap-producer(bst-producer) bootstrap-server(bst-server) client，他们之间的关系可以去网上找这里主要介绍部署这四个工程的方法

1 relay 侦听端口为 11115

1.1 relay.properties

databus.relay.container.httpPort=11115
databus.relay.container.jmx.rmiEnabled=false
databus.relay.eventBuffer.allocationPolicy=DIRECT_MEMORY
databus.relay.eventBuffer.queuePolicy=OVERWRITE_ON_WRITE
databus.relay.eventLogReader.enabled=false
databus.relay.eventLogWriter.enabled=false
databus.relay.schemaRegistry.type=FILE_SYSTEM
databus.relay.eventBuffer.maxSize=1024000000
databus.relay.eventBuffer.readBufferSize=10240
databus.relay.eventBuffer.scnIndexSize=10240000
#databus.relay.physicalSourcesConfigsPattern=conf/sources.json
databus.relay.dataSources.sequenceNumbersHandler.file.scnDir=./maxScn
databus.relay.startDbPuller=true

1.2 start.sh

cd `dirname $0`/..

script_dir=./bin
source $script_dir/setup.inc
source $script_dir/setup-relay.inc

cli_overrides=

# DEFAULT VALUES
relay_type=default

if [ ! -z "${jvm_gc_log}" ] ; then

   cli_overrides="-c '$cli_overrides'"
fi

#main_class=com.linkedin.databus.relay.example.PersonRelayServer;
main_class=com.linkedin.databus2.relay.DatabusRelayMain

cmdline="java -cp ${cp} ${jvm_arg_line} ${main_class} ${java_arg_line} $cli_overrides $*"
echo $cmdline
$cmdline 2>&1 > ${relay_out_file} &
echo $! > ${relay_pid_file}

启动

sh start.sh -db_relay_config=conf/sources.json

这个和官方默认提供的 start-example-relay.sh 大部分是一样的只是把main_cliass改成了DatabusRelayMain 去掉了原来需要启动时传参的person
然后启动的时候指定 sources.json
当然你也可以用原先的 PersonRelayServer 这个类已经把sources-person.json定死了或者你也可以在sh文件中定死
比较一下 PersonRelayServer 与 DatabusRelayMain 中的main方法发现 PersonRelayServer 中就多了一行

cli.setDefaultPhysicalSrcConfigFiles("conf/sources-person.json");

2 bst-producer 侦听端口为 11116

2.1 在mysql中添加相应的数据库

默认的数据库名称为 bootstarp 你可以在配置文件中更改
然后运行 cdsddl.tab 文件把相应的表数据添加到mysql中

CREATE TABLE bootstrap_sources (
  id int(11) NOT NULL auto_increment,
  src varchar(255) NOT NULL,
  status TINYINT default 1,
  logstartscn bigint(20) default 0,

databus.client.runtime.bootstrap.service(1).port=11117
databus.client.runtime.bootstrap.service(1).sources=com.linkedin.events.example.person.Person

4.2 启动类 ClientMain.java

public class ClientMain {
    public static void main(String[] args) throws Exception {
        Properties startupProps = ServerContainer.processCommandLineArgs(args);
        ConfigLoader configLoader = new ConfigLoader(
                "databus.client.", new DatabusHttpClientImpl.Config());
        DatabusHttpClientImpl.StaticConfig clientConfig = configLoader.loadConfig(startupProps);
        DatabusHttpClientImpl client = new DatabusHttpClientImpl(clientConfig);
        PersonConsumer personConsumer = new PersonConsumer();
        client.registerDatabusStreamListener(personConsumer, null, PersonClientMain.PERSON_SOURCE,
                PersonClientMain.ANIMAL_SOURCE);
        client.registerDatabusBootstrapListener(personConsumer, null, PersonClientMain.PERSON_SOURCE,
                PersonClientMain.ANIMAL_SOURCE);
        client.startAndBlock();
    }
}

4.3 start.sh


cd `dirname $0`/..


script_dir=./bin
source $script_dir/setup.inc
source $script_dir/setup-client.inc

cli_overrides=

# DEFAULT VALUES
client_type=default
jvm_gc_log=${logs_dir}/client-gc.log

# JVM ARGUMENTS
jvm_direct_memory_size=40g
jvm_direct_memory="-XX:MaxDirectMemorySize=${jvm_direct_memory_size}"
jvm_min_heap_size="1024m"
jvm_min_heap="-Xms${jvm_min_heap_size}"
jvm_max_heap_size="1024m"
jvm_max_heap="-Xmx${jvm_max_heap_size}"

jvm_gc_options="-XX:NewSize=512m -XX:MaxNewSize=512m -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:CMSInitiatingOccupancyFraction=75 -XX:+UseCMSInitiatingOccupancyOnly -XX:SurvivorRatio=6 -XX:MaxTenuringThreshold=7"
jvm_gc_log_option="-XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintTenuringDistribution "
if [ ! -z "${jvm_gc_log}" ] ; then
  jvm_gc_log_option="${jvm_gc_log_option} -Xloggc:${jvm_gc_log}"
fi

jvm_arg_line="-d64 ${jvm_direct_memory} ${jvm_min_heap} ${jvm_max_heap} ${jvm_gc_options} ${jvm_gc_log_option} -ea"

log4j_file_option="-l ${conf_dir}/client_log4j.properties"
config_file_option="-p ${conf_dir}/client.properties"

java_arg_line="${config_file_option} ${log4j_file_option}"

if [ ! -z "$cli_overrides" ] ; then
   cli_overrides="-c '$cli_overrides'"
fi


#main_class=com.linkedin.databus.client.example.PersonClientMain;
main_class=com.linkedin.databus.client.example.ClientMain;


cmdline="java -cp ${cp} ${jvm_arg_line} ${main_class} ${java_arg_line} $cli_overrides $*"
echo $cmdline
$cmdline 2>&1 > ${client_out_file} &
echo $! > ${client_pid_file}

与老的 start-example-client.sh 相比也只是把 main_class 改了同时删除了启动是所需传的person 参数

5 相应的 setup-xxx.inc stop-xxxx.sh 文件也最好改一下

如
setup-client.inc

var_dir=${script_dir}/../var

if [ ! -d ${var_dir} ] ; then
  mkdir -p ${var_dir}
fi

client_pid_file=${var_dir}/databus2-client.pid
client_out_file=${logs_dir}/databus2-client.out

setup-relay.inc

var_dir=${script_dir}/../var

if [ ! -d ${var_dir} ] ; then
  mkdir -p ${var_dir}
fi

relay_pid_file=${var_dir}/databus2-relay.pid
relay_out_file=${logs_dir}/databus2-relay.out
