本文主要介绍安装pulsar和pulsar manager的过程，在安装过程中解决了各种问题。解决了zookeeper版本域pulsar不匹配，8080端口被zookeeper占用。希望对大家有所帮助。

1.安装准备（3台机器）

官网地址：Pulsar官网集群安装地址
（1） jdk安装,jdk8及以上
（2）单独安装zookeeper安装完成要求版本要在3.6.3及以上，否则或报错，后面有我报错的解决方法
（3）确保3台机器都安装完成
（4）防火墙关闭、ssh免登录

（5）同步脚本多台服务器，

修改hostname:hadoop192 hadoop193 hadoop191

#!/bin/bash
#1. 判断参数个数
if [ $# -lt 1 ]
then
echo Not Enough Arguement!
exit;
fi
#2. 遍历集群所有机器
for host in hadoop192 hadoop193 hadoop191
do
echo ==================== $host ====================
#3. 遍历所有目录，挨个发送
for file in $@
do
#4. 判断文件是否存在
if [ -e $file ]
then
#5. 获取父目录
pdir=$(cd -P $(dirname $file); pwd)
#6. 获取当前文件的名称
fname=$(basename $file)
ssh $host "mkdir -p $pdir"
rsync -av $pdir/$fname $host:$pdir
else
echo $file does not exists!
fi
done
done

2.集群规划

集群名称	机器IP	服务名称
hadoop191	192.168.10.191	JKD,Zookeeper,BookKeeper,Broker
hadoop192	192.168.10.192	JKD,Zookeeper,BookKeeper,Broker
hadoop193	192.168.10.193	JKD,Zookeeper,BookKeeper,Broker

3.验证安装的jdk和Zookeeper

(1)验证jdk
java -version

[root@hadoop191 ~]# java -version
java version "1.8.0_212"
Java(TM) SE Runtime Environment (build 1.8.0_212-b10)
Java HotSpot(TM) 64-Bit Server VM (build 25.212-b10, mixed mode)
[root@hadoop191 ~]#

(2)验证zookeeper
由于信息较长，删除了部分日志内容

[root@hadoop193 apache-zookeeper-3.5.7-bin]# bin/zkCli.sh -server 127.0.0.1:2181
Connecting to 127.0.0.1:2181
2022-04-30 16:18:36,097 [myid:] - INFO  [main:Environment@109] - Client 
2022-04-30 16:18:36,158 [myid:127.0.0.1:2181] - INFO  [main-SendThread(127.0.0.1:2181):ClientCnxn$SendThread@959] - Socket connection established, initiating session, client: 127.0.0.1:44318, server: localhost/127.0.0.1:2181
2022-04-30 16:18:36,175 [myid:127.0.0.1:2181] - INFO  [main-SendThread(127.0.0.1:2181):ClientCnxn$SendThread@1394] - Session establishment complete on server localhost/127.0.0.1:2181, sessionid = 0x300004d3c460000, negotiated timeout = 30000


WATCHER::


WatchedEvent state:SyncConnected type:None path:null
[zk: 127.0.0.1:2181(CONNECTED) 0]

4.pulsar集群部署模式

(1)下载

https://archive.apache.org/dist/pulsar/
选择自己的版本

cd opt/software


wget 
https://www.apache.org/dyn/mirrors/mirrors.cgi?action=download&filename=pulsar/pulsar-2.10.0/apache-pulsar-2.10.0-bin.tar.gz

(2)解压

[root@hadoop191 software]# tar  -zxvf apache-pulsar-2.10.0-bin.tar.gz -C ../module/

(3)创建软连接

[root@hadoop191 module]# ln -s apache-pulsar-2.10.0 pulsar_2.10.0

软连接创建后结果

5.修改bookkeeper配置

（1）进入配置目录

cd opt/module/apache-pulsar-2.10.0/conf

（2）打开文件bookkeeper.conf

[root@hadoop191 conf]# vim bookkeeper.conf

（3）修改文件内容
vim中快速到某行：退出编辑模式（esc），然后输入冒号+行号

：行号

#39行
journalDirectory=/opt/module/apache-pulsar-2.10.0/tmp/journal


# 56行：本机IP 或hostname
advertisedAddress=hadoop191


#405行,创建临时目录
ledgerDirectories=/opt/module/apache-pulsar-2.10.0/tmp/ledgers


#633行：zookeeker集群
zkServers=hadoop191:2181,hadoop192:2181,hadoop193:2181

6.修改broker配置

(1)进入broker.conf文件
cd opt/module/apache-pulsar-2.10.0/conf
[root@hadoop191 conf]# vim broker.conf
(2)修改vroker.conf的内容
#23行 Zookeeper quorum connection string
 zookeeperServers=hadoop191:2181,hadoop192:2181,hadoop193:2181


#26行 Configuration Store connection string
 configurationStoreServers=hadoop191:2181,hadoop192:2181,hadoop193:2181


#47行，本地ip地址或者服务器名称hostname
advertisedAddress=hadoop191


#101行，修改集群名称
clusterName=pulsar-cluser

7.将配置好的结果分发到另外2台机器

使用同步脚本进行同步

[root@hadoop191 ~]# sh synfile.sh /opt/module/apache-pulsar-2.10.0

8.在另外2台机器创建软连接

[root@hadoop193 module]# ln -s apache-pulsar-2.10.0/ pulsar_2.10.0

9.修改另外2台broker和bookies的地址

vim  bookkeeper.conf 


# 56行：本机IP 或hostname
advertisedAddress=hadoop192


vim broker.conf 


#61行，本地ip地址或者服务器名称hostname
advertisedAddress=hadoop192

10.启动zookeeper集群并检查状态

3台服务器都都启动zookeeper

[root@hadoop193 apache-zookeeper-3.5.7-bin]# bin/zkServer.sh start


检查状态
[root@hadoop193 apache-zookeeper-3.5.7-bin]# bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: opt/module/apache-zookeeper-3.5.7-bin/bin/../conf/zoo.cfg
Client port found: 2181. Client address: localhost.
Mode: leader
[root@hadoop193 apache-zookeeper-3.5.7-bin]#

应该是有2个follower和一个leader

11.初始化Pulsar元数据信息

（1）进入目录/opt/module/apache-pulsar-2.10.0

cd opt/module/apache-pulsar-2.10.0/bin

（2）执行初始化

如果一次初始化没有成功，可以再初始化一次试试

只在一台机器上执行

#执行初始化脚本
./pulsar initialize-cluster-metadata \
--cluster pulsar-cluster \
--zookeeper hadoop191:2181,hadoop192:2181,hadoop193:2181 \
--configuration-store hadoop191:2181,hadoop192:2181,hadoop193:2181 \
--web-service-url http://hadoop191:8080,hadoop192:8080,hadoop193:8080 \
--web-service-url-tls https://hadoop191:8443,hadoop192:8443,hadoop193:8443 \
--broker-service-url pulsar://hadoop191:6650,hadoop192:6650,hadoop193:6650 \
--broker-service-url-tls pulsar+ssl://hadoop191:6651,hadoop192:6651,hadoop193:6651

(3)元素说明

集群元数据说明:
cluster
集群名称
zookeeper
ZooKeeper集群连接参数，仅需要包含ZooKeeper集群中的一个节点即可
configuration-store
Pulsar实例的配置存储集群（ZooKeeper），多集群部署时才会发挥作用，需要另外部署ZooKeeper集群，但是单集群部署时可以和–zookeeper参数设置一样，只需要包含ZooKeeper集群中的一个节点即可
web-service-url
集群Web服务的URL+端口，URL是一个标准的DNS名称，默认端口8080，不建议修改。
web-service-url-tls
集群Web提供TLS服务的URL+端口，端口默认8443，不建议修改。
broker-service-url
集群brokers服务URL，URL中DNS的名称和Web服务保持一致，URL使用pulsar替代http/http，端口默认6650，不建议修改。
broker-service-url-tls
集群brokers提供TLS服务的URL，默认端口6551，不建议修改。

（4）初始化错误

        ... 5 more

（5）分析问题：

（5.1）检查原来的配置是否正确
没有任何问题
（5.2）zookeeper版本错误
我自己装的版本是3.5.7与Pulsar中需要的版本3.6.3不一致。
发现错误信息中有zookeeper版本是3.6.3
所以准备重新装给新的版本zookeeper

（6）解决方法：下载新的zookeeper 3.6.3
下载完后，进行初始化，初始化成功，问题解决

（7）初始化完成，只执行一次
初始化后，部分信息如下

2022-05-01T07:03:58,647+0800 [main-EventThread] INFO  org.apache.zookeeper.ClientCnxn - EventThread shut down for session: 0x300000c76710000
2022-05-01T07:03:58,752+0800 [main] INFO  org.apache.zookeeper.ZooKeeper - Session: 0x300000c76710001 closed
2022-05-01T07:03:58,752+0800 [main-EventThread] INFO  org.apache.pulsar.metadata.impl.ZKSessionWatcher - Got ZK session watch event: WatchedEvent state:Closed type:None path:null
2022-05-01T07:03:58,752+0800 [main-EventThread] INFO  org.apache.zookeeper.ClientCnxn - EventThread shut down for session: 0x300000c76710001
2022-05-01T07:03:58,753+0800 [main] INFO  org.apache.pulsar.PulsarClusterMetadataSetup - Cluster metadata for 'pulsar-cluster' setup correctly

12.初始化Pulsar中的bookkeeper

只需要执行一次，以后再使用也不用初始化

（1）进入目录

cd opt/module/apache-pulsar-2.10.0/bin

（2）执行初始化

./bookkeeper shell metaformat

（3）输入Y

er.ZooKeeperWatcherBase - ZooKeeper client is connected now.
Ledger root already exists. Are you sure to format bookkeeper metadata? This may cause data loss. (Y or N) y

（4）结果信息如下

如果有错误信息可以再初始化一次

Ledger root already exists. Are you sure to format bookkeeper metadata? This may cause data loss. (Y or N) y
2022-05-01T07:15:33,874+0800 [main] INFO  org.apache.bookkeeper.discover.ZKRegistrationManager - Successfully formatted BookKeeper metadata
2022-05-01T07:15:33,979+0800 [main-EventThread] INFO  org.apache.zookeeper.ClientCnxn - EventThread shut down for session: 0x100000c57f30002
2022-05-01T07:15:33,979+0800 [main] INFO  org.apache.zookeeper.ZooKeeper - Session: 0x100000c57f30002 closed

13.启动过程bookie

3个节点都需要依次启动
（1）进入目录

cd /opt/module/apache-pulsar-2.10.0/bin

（2）执行启动
每台机器都执行

./pulsar-daemon start bookie

（3）执行结果

doing start bookie ...
starting bookie, logging to opt/module/apache-pulsar-2.10.0/logs/pulsar-bookie-hadoop191.log
Note: Set immediateFlush to true in conf/log4j2.yaml will guarantee the logging event is flushing to disk immediately. The default behavior is switched off due to performance considerations.
[root@hadoop191 bin]#

（4）验证是否启动成功

三台都进行验证

./bookkeeper shell bookiesanity

5）输出信息中有下面信息说明启动成功

2022-05-01T07:26:21,319+0800 [main] INFO  org.apache.bookkeeper.tools.cli.commands.bookie.SanityTestCommand - Bookie sanity test succeeded

可以通过jps进行验证

14.启动过程-broker

每台机器都执行
（1）进入目录

cd /opt/module/apache-pulsar-2.10.0/bin

（2）执行启动broker

./pulsar-daemon start broker

（3）启动结果

（4）查看集群 brokers 节点情况

./pulsar-admin brokers list pulsar-cluster

（5）检查问题

查看日志，发现端口被占用8080

led to bind to 0.0.0.0:8080
        at org.apache.pulsar.broker.web.WebService.start(WebService.java:253) ~[org.apache.pulsar-pulsar-broker-2.9.2.jar:2.9.2]
        at org.apache.pulsar.broker.PulsarService.start(PulsarService.java:686) ~[org.apache.pulsar-pulsar-broker-2.9.2.jar:2.9.2]
        ... 2 more
Caused by: java.io.IOException: Failed to bind to 0.0.0.0:8080

（6）检查端口号

netstat -anp |grep 8080
ps -ef |grep 2333

（7）解决端口被占用的方法：修改zookeeper配置有2种方法
（7.1）修改zookeeper端口

cd opt/module/apache-zookeeper-3.6.3-bin/conf


vim zoo.cfg


#修改或增加端口
# admin port 
admin.serverPort=8887

（7.2）在zookeeper中, 如果不需要 AdminServer ，可以直接禁用：打开 zoo.cfg 配置文件，直接添加以下语句即可。

# 禁用 AdminServer 服务 
admin.enableServer=false

（8）重新启动zookeeper

所有已经启动的服务关闭重新启动
再次启动zookeeper
启动bookie
启动broker

终于启动成功

（9）解决端口冲突8080方法2:修改pulsar的端

（9.1）每台机器都修改

cd opt/module/apache-pulsar-2.10.0/conf


vim broker.conf 


# Port to use to server HTTP request
webServicePort=8008

（9.2）每台机器修改

cd opt/module/apache-pulsar-2.10.0/conf


vim client.conf


client.conf里的webServiceUrl=http://10.50.30.178:8008

15.验证集群是否正常使用

（1）查看集群 brokers 节点情况

cd opt/module/apache-pulsar-2.10.0/bin


[root@hadoop191 bin]# ./pulsar-admin brokers list pulsar-cluster
hadoop193:8080
hadoop192:8080
hadoop191:8080
[root@hadoop191 bin]#

(2)消费者

./pulsar-client consume \
persistent://public/default/pulsar-cluster \
-n 100 \
-s "consumer-cluster" \
-t "Exclusive"

（3）生产者

./pulsar-client produce \
  persistent://public/default/pulsar-cluster \
  -n 1 \
  -m "Hello Pulsar"

消费掉消息

到此结束安装

16.安装Pulsar监控工具Pulsar Manager

Pulsar Manager官网地址

(1)下载

cd opt/module
wget https://dist.apache.org/repos/dist/release/pulsar/pulsar-manager/pulsar-manager-0.2.0/apache-pulsar-manager-0.2.0-bin.tar.gz

(2)解压

#解压
tar -zxvf apache-pulsar-manager-0.2.0-bin.tar.gz

（3）进入目录

#进入目录
