zookeeper 部署

官网：

https://zookeeper.apache.org/

download

 

 

 

 

 

 

 

 

 

 

 

 

 下载完成后 赋值文件到centos  /opt/software

 

 

单机部署

解压到/opt/module

 tar -zxvf apache-zookeeper-3.7.1-bin.tar.gz -C /opt/module

重命名文件包zookeeper3.7.1

 mv apache-zookeeper-3.7.1-bin/ zookeeper3.7.1

修改配置文件 zoo_sample.cfg (先创建zkData文件夹 mkdir zdData）

 

修改 zoo_sample.cfg 为 zoo.cfg

mv zoo_sample.cfg zoo.cfg

启动服务

 

bin/zkServer.sh start

注意：参数start前面没有 杠-

 

 

启动客户端

[root@192 bin]# ./zkCli.sh

 

集群部署

 

修改zookeeper的配置文件 zoo.cfg
增加配置：
server.MYID=HOSTNAME:PORT_BETWEEN_SERVER_CLIENT:PORT_REELECTION
MYID:zkData/myid的内容
HOSTNAME:/etc/hosts 中映射的主机名
PORT_BETWEEN_SERVER_CLIENT：Leader与Follower 之间通信的端口
PORT_REELECTION：重新选举的PORT

zoo.cfg增加如下配置

server.2=machine136:2888:3888
server.3=machine137:2888:3888
server.4=machine138:2888:3888

配置完成 一定关闭防火墙！一定关闭防火墙！一定关闭防火墙！

systemctl stop firewalld

 

 使用 curlator 包实现进程锁测试
