一、集群组成说明
1. 搭建 Pulsar 集群至少需要 3 个组件：ZooKeeper 集群、BookKeeper 集群和 broker 集群（Broker 是 Pulsar 的自身实例)。这三个集群组件如下：
ZooKeeper 集群（3 个 ZooKeeper 节点组成）
bookie 集群（也称为 BookKeeper 集群，3 个 BookKeeper 节点组成）
broker 集群（3 个 Pulsar 节点组成）
2. Pulsar 的安装包已包含了搭建集群所需的各个组件库。无需单独下载 ZooKeeper 安装包和 BookKeeper 安装包。
二、安装JDK
在 3 台 Linux 裸机服务器上安装 JDK（要求版本不低于 JDK 8）安装略过
下载最新版本pulsar,https://pulsar.apache.org/download/ 上传至3台服务器
解压安装包到指定目录
$tar -zxvf apache-pulsar-2.3.2-bin.tar.gz -C /data
三、配置部署 ZooKeeper 集群
/data/apache-pulsar-2.3.2$ cd /data/apache-pulsar-2.3.2/conf
/data/apache-pulsar-2.3.2$ vim zookeeper.conf

# 新建文件目录
/data/apache-pulsar-2.3.2$ mkdir -PV /data/zookeeper/zookeeper
/data/apache-pulsar-2.3.2$ mkdir -PV /data/zookeeper/logs
# 新建文件 myid，分别在指定的sever上写入配置文件中指定的编号
server.1服务器上
echo 1 > data/zookeeper/zookeeper/myid
server.2服务器上
/data/apache-pulsar-2.3.2$ echo 2 > data/zookeeper/zookeeper/myid
server.3服务器上
/data/apache-pulsar-2.3.2$ echo 3 > data/zookeeper/zookeeper/myid
# 执行后台运行命令
/data/apache-pulsar-2.3.2$ bin/pulsar-daemon start zookeeper
# 执行 zookeeper 客户端连接命令
/data/apache-pulsar-2.3.2$ bin/pulsar zookeeper-shell
#注意Enter 键进入命令行界面后，可完全使用 ZooKeeper 的各种命令，如ls、get等命令。使用quit命令退出
#在任一个 ZooKeeper 节点，初始化集群元数据。
/data/apache-pulsar-2.3.2$bin/pulsar initialize-cluster-metadata \
--cluster pulsar-cluster-zk \
--zookeeper HOSTNAMEIP:2181 \
--configuration-store HOSTNAMEIP:2181 \
--web-service-url http://HOSTNAMEIP:8080 \
--web-service-url-tls https://HOSTNAMEIP:8443 \
--broker-service-url pulsar://HOSTNAMEIP:6650 \
--broker-service-url-tls pulsar+ssl://HOSTNAMEIP:6651
#查看集群元数据是否初始化成功，看到如下图所内容，表示初始化成功
$ bin/pulsar zookeeper-shell
四、配置部署 BookKeeper 集群
编辑 bookkeeper.conf 文件
/data/apache-pulsar-2.3.2$ vim conf/bookkeeper.conf
|
advertisedAddress=HOSTNAMEIP zkServers=ZKSERVER1:2181,ZKSERVER2:2181,ZKSERVER3:2181 journalDirectory=/data/bookkeeper/journal ledgerDirectories=/data/bookkeeper/ledgers |
#创建bookie所需要目录
/data/apache-pulsar-2.3.2$ mkdir -pv /data/bookkeeper/
#执行初始化元数据命令；若出现提示，输入 Y，继续（只需在一个bookie节点执行一次）
/data/apache-pulsar-2.3.2$ bin/bookkeeper shell metaformat
#以后台进程启动bookie
/data/apache-pulsar-2.3.2$ bin/pulsar-daemon start bookie
#按照以上步骤，启动另外两个 bookie 节点。
如果出现报错
就是/data/bookkeeper/journal/current/VERSION /data/bookkeeper/ledgers/current/VERSION 这两个文件与zk上的文件不一致造成的，将journal 和ledgers文件删除，在把zk的注册信息删除，重新注册一遍就好
验证是否启动成功
/data/apache-pulsar-2.3.2$ bin/bookkeeper shell bookiesanity
/data/apache-pulsar-2.3.2$ vim logs/pulsar-bookie-HOSTNAME.out.2
如果验证出现以上错误。
#解决方案：查看8000端口是否被占用
$egrep -v '^#|^$' conf/bookkeeper.conf
将prometheusStatsHttpPort=8000 端口更改掉
将bookie关闭
/data/apache-pulsar-2.3.2$ $bin/pulsar-daemon stop bookie
启动bookie
/data/apache-pulsar-2.3.2$ $bin/pulsar-daemon start bookie
验证是否启动成功，出现如下显示，表示启动成功Bookie
/data/apache-pulsar-2.3.2$ bin/bookkeeper shell bookiesanity
五、部署配置 Broker 集群
/data/apache-pulsar-2.3.2$ vim conf/broker.conf
|
zookeeperServers=ZKSERVER1:2181,ZKSERVER2:2181,ZKSERVER3:2181 configurationStoreServers=ZKSERVER1:2181,ZKSERVER2:2181,ZKSERVER3:2181 advertisedAddress=HOSTNAME clusterName=pulsar-cluster-zk |
#以后台进程启动 broker
/data/apache-pulsar-2.3.2$ bin/pulsar-daemon start broker
查看集群 brokers 节点情况
/data/apache-pulsar-2.3.2$ bin/pulsar-admin brokers list pulsar-cluster
六、docker 安装 apachepulsar/pulsar-dashboard
#docker安装略过
#docker run --name pulsar-dashboard -dit -p 80:80 -e SERVICE_URL=http://PULSARSEVERIP:8080 apachepulsar/pulsar-dashboard
通过浏览器访问docker 宿主机IP
