zookeeper同一台服务器创建伪集群

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

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
