在 CentOS 安装 zookeeper

*jpfly* 2023-04-15 原文

zookeeper 有三种安装方式
1、单机模式，只是在一台服务器上运行一个 zookeeper 实例，适合学习测试用。
2、集群模式，在多台服务器上运行多个实例，各个实例之间通过网络连接互相通信，组成集群，适合生产环境。
3、伪集群模式，在一台服务器上运行多个实例，互相之间通过网络通信，组成集群，适合学习测试用。

安装环境

CentOS 7
java 11.0.10
zookeeper 3.8.0 点击下载
这里下载二进制包，而不是源码包，要不然还得自己编译。
下载之后上传到服务器之后解压一下，如图

进入到解压后的目录
bin 脚本文件目录，启动脚本，命令脚本
conf 配置文件目录
docs 文档目录
lib 运行依赖的一些 jar 包

单机模式安装

1、新建 standalone 目录

mkdir standalone

2、进入到 standalone 把解压的 zookeeper 复制进来，改名 zk

[root@localhost standalone]# cp -r ../apache-zookeeper-3.8.0-bin .
[root@localhost standalone]# ll
总用量 0
drwxr-xr-x. 6 root root 133 8月  15 21:34 apache-zookeeper-3.8.0-bin
[root@localhost standalone]# mv apache-zookeeper-3.8.0-bin/ zk
[root@localhost standalone]# ll
总用量 0
drwxr-xr-x. 6 root root 133 8月  15 21:34 zk
[root@localhost standalone]#

3、进入到配置文件目录，复制 zoo_sample.cfg 为 zoo.cfg

[root@localhost standalone]# cd zk/conf/
[root@localhost conf]# 
[root@localhost conf]# ll
总用量 16
-rw-r--r--. 1 root root  535 8月  15 21:34 configuration.xsl
-rw-r--r--. 1 root root 4559 8月  15 21:34 logback.xml
-rw-r--r--. 1 root root 1183 8月  15 21:34 zoo_sample.cfg
[root@localhost conf]# cp zoo_sample.cfg zoo.cfg        
[root@localhost conf]# ll
总用量 20
-rw-r--r--. 1 root root  535 8月  15 21:34 configuration.xsl
-rw-r--r--. 1 root root 4559 8月  15 21:34 logback.xml
-rw-r--r--. 1 root root 1183 8月  15 21:37 zoo.cfg
-rw-r--r--. 1 root root 1183 8月  15 21:34 zoo_sample.cfg
[root@localhost conf]#

4、修改 zoo.cfg 配置文件

[root@localhost conf]# vim zoo.cfg

这里主要修改了 dataDir（用来存放数据文件，版本文件）和 clientPort（端口号，用于客户端连接）

5、启动 zookeeper 服务

进入到 bin 目录下，执行 zkServer.sh 脚本文件

[root@localhost bin]# ./zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /home/tiger/zookeeper/standalone/zk/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@localhost bin]#

查看 zookeeper 运行状态

[root@localhost bin]# ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /home/tiger/zookeeper/standalone/zk/bin/../conf/zoo.cfg
Client port found: 12181. Client address: localhost. Client SSL: false.
Mode: standalone
[root@localhost bin]#

停止服务

[root@localhost bin]# ./zkServer.sh stop
ZooKeeper JMX enabled by default
Using config: /home/tiger/zookeeper/standalone/zk/bin/../conf/zoo.cfg
Stopping zookeeper ... ./zkServer.sh: 第 219 行:kill: (3081) - 没有那个进程
STOPPED
[root@localhost bin]#

6、客户端连接

重新启动 zookeeper 服务，使用 zkCli.sh 脚本连接 zookeeper 服务

[root@localhost bin]# ./zkServer.sh start 
ZooKeeper JMX enabled by default
Using config: /home/tiger/zookeeper/standalone/zk/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@localhost bin]# ./zkCli.sh -server localhost:12181
Connecting to localhost:12181

伪集群模式安装

在多台服务器上安装 zookeeper 集群可能没有条件，那么可以在单台服务器上安装 zookeeper 伪集群体验一把，一台机器上部署多个 zookeeper 实例，那么就得保证端口不能冲突，dataDir 也不能一样，另外，还得再 dataDir 对应的目录里新建 myid 文件用于唯一指定 zookeeper 实例。

1、新建集群目录，复制二进制包

[root@localhost zookeeper]# ll
总用量 12880
drwxr-xr-x. 6 root root      133 8月  15 21:26 apache-zookeeper-3.8.0-bin
-rw-r--r--. 1 root root 13185104 8月  15 21:12 apache-zookeeper-3.8.0-bin.tar.gz
drwxr-xr-x. 4 root root       28 8月  15 21:40 standalone
[root@localhost zookeeper]# mkdir cluster
[root@localhost zookeeper]# ll
总用量 12880
drwxr-xr-x. 6 root root      133 8月  15 21:26 apache-zookeeper-3.8.0-bin
-rw-r--r--. 1 root root 13185104 8月  15 21:12 apache-zookeeper-3.8.0-bin.tar.gz
drwxr-xr-x. 2 root root        6 8月  15 21:55 cluster
drwxr-xr-x. 4 root root       28 8月  15 21:40 standalone
[root@localhost zookeeper]# cd cluster/
[root@localhost cluster]# cp -r ../apache-zookeeper-3.8.0-bin zk01
[root@localhost cluster]# ll
总用量 0
drwxr-xr-x. 6 root root 133 8月  15 21:56 zk01
[root@localhost cluster]#

2、创建 data 目录和 myid 文件

在 zk01 下创建 data 目录

[root@localhost cluster]# cd zk01/
[root@localhost zk01]# mkdir data
[root@localhost data]# echo 1 > myid
[root@localhost data]# ll
总用量 4
-rw-r--r--. 1 root root 2 8月  15 22:04 myid
[root@localhost data]# cat myid 
1
[root@localhost data]#

3、修改配置文件

[root@localhost zk01]# cd conf/
[root@localhost conf]# 
[root@localhost conf]# ll
  用量 16
-rw-r--r--. 1 root root  535 8月  15 21:56 configuration.xsl
-rw-r--r--. 1 root root 4559 8月  15 21:56 logback.xml
-rw-r--r--. 1 root root 1183 8月  15 21:56 zoo_sample.cfg
[root@localhost conf]# cp zoo_sample.cfg zoo.cfg        
[root@localhost conf]# vim zoo.cfg

在配置文件末尾添加如下配置

server.1=localhost:12881:13881
server.2=localhost:12882:13882
server.3=localhost:12883:13883
#server.服务器ID(myid文件里的值)=服务器IP地址：服务器之间通信端⼝：服务器之间投票选举端⼝

4、复制 zk01，产生 zk02，zk03 并修改配置文件，myid 文件

[root@localhost cluster]# ll
总用量 0
drwxr-xr-x. 7 root root 145 8月  15 21:57 zk01
[root@localhost cluster]# cp -r zk01 zk02
[root@localhost cluster]# cp -r zk01 zk03
[root@localhost cluster]# ll
总用量 0
drwxr-xr-x. 7 root root 145 8月  15 21:57 zk01
drwxr-xr-x. 7 root root 145 8月  15 22:14 zk02
drwxr-xr-x. 7 root root 145 8月  15 22:14 zk03
[root@localhost cluster]#

5、启动集群

[root@localhost cluster]# ./zk01/bin/zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /home/tiger/zookeeper/cluster/zk01/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@localhost cluster]# ./zk02/bin/zkServer.sh start 
ZooKeeper JMX enabled by default
Using config: /home/tiger/zookeeper/cluster/zk02/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@localhost cluster]# ./zk03/bin/zkServer.sh start 
ZooKeeper JMX enabled by default
Using config: /home/tiger/zookeeper/cluster/zk03/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@localhost cluster]# ./zk03/bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /home/tiger/zookeeper/cluster/zk03/bin/../conf/zoo.cfg
Client port found: 12183. Client address: localhost. Client SSL: false.
Mode: follower
[root@localhost cluster]# ./zk02/bin/zkServer.sh status 
ZooKeeper JMX enabled by default
Using config: /home/tiger/zookeeper/cluster/zk02/bin/../conf/zoo.cfg
Client port found: 12182. Client address: localhost. Client SSL: false.
Mode: leader
[root@localhost cluster]# ./zk01/bin/zkServer.sh status 
ZooKeeper JMX enabled by default
Using config: /home/tiger/zookeeper/cluster/zk01/bin/../conf/zoo.cfg
Client port found: 12181. Client address: localhost. Client SSL: false.
Mode: follower
[root@localhost cluster]#

可以看到 3 个实例，两个角色是 follower，一个是 leader

6、客户端连接一下

[root@localhost cluster]# ./zk01/bin/zkCli.sh -server localhost:12183
Connecting to localhost:12183
