时间：2022-10-17 14:34:13

下载zk

wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.7.0/apache-zookeeper-3.7.0-bin.tar.gz

解压

tar -zxvf apache-zookeeper-3.7.0-bin.tar.gz

copy配置成3份

# 进入zk的conf目录

cd conf

# copy1

cp zoo.cfg zoo1.cfg

# copy2

cp zoo.cfg zoo2.cfg

# copy3

cp zoo.cfg zoo3.cfg
zoo1.cfg

server.3=47.103.72.160:2889:3889

#server.a=b:c:d , a:表示第几号服务器，b:服务器的ip地址,

#c:集群中与 leader 交换信息的端口,d:当 leader 服务器挂了，通过这个端口来重新选举 leader

#因为是在同一台机器上搭建的伪集群，所有 c,d 都不能一样

修改clientPort属性 (客户端连接 zk 服务器的端口，zk 监听这个端口，接受客户端请求)

修改dataDir属性(数据保存地址)

修改dataLogDir属性(日志保存地址)

server.n (集群地址,n 是dataDir目录下的myid文件中内容,用来标记该服务器在集群中的地址)

日志路径创建3份

# 进入log

cd log

# 创建zk1日志目录

mkdir log1

# 创建zk2日志目录

mkdir log2

# 创建zk3日志目录

mkdir log4

数据路径创建3份

# 进入data

cd data

# 创建zk1保存数据目录

mkdir zk1

cd zk1

vim myid

输入:1

保存退出

# 创建zk2保存数据目录

mkdir zk2

cd zk2

vim myid

输入:2

保存退出

# 创建zk3保存数据目录

mkdir zk3

cd zk3

vim myid

输入:3

保存退出

zk命令

cd bin

# 启动

sh zkServer.sh start zoo1.cfg

sh zkServer.sh start zoo2.cfg

sh zkServer.sh start zoo3.cfg

# 状态

sh zkServer.sh status zoo1.cfg

sh zkServer.sh status zoo2.cfg

sh zkServer.sh status zoo3.cfg

# 关闭

sh zkServer.sh stop zoo1.cfg

sh zkServer.sh stop zoo2.cfg

sh zkServer.sh stop zoo3.cfg
