zookeeper 集群搭建 及启动关闭脚本
1准备奇数台机子3，5，7
我准备的是三台
192.168.58.81 zookeeper-1
192.168.58.82 zookeeper-2
192.168.58.83 zookeeper-3
下载jdk 把他配置环境变量并检查是否是环境变量 echo $JAVA_HOME
cd /opt/software wget http://mirrors.hust.edu.cn/apache/zookeeper/zookeeper-3.4.13/zookeeper-3.4.13.tar.gztar -xzvf apache-zookeeper-3.6.2-bin.tar.gz -C /usr/mv /usr/apache-zookeeper-3.6.2-bin/ /usr/zookeepercd /usr/zookeeper/vim /etc/profile
source /etc/profileecho $ZK_HOMEcp conf/zoo_sample.cfg conf/zoo.cfgvim conf/zoo.cfg最后一行加server.1=zookeeper-1:2888:3888server.2=zookeeper-2:2888:3888server.3=zookeeper-3:2888:3888
保存退出mkdir /usr/zookeeper/datavi /etc/hosts最后一行添加
192.168.58.81 zookeeper-1
192.168.58.82 zookeeper-2
192.168.58.83 zookeeper-3
保存退出vim /usr/zookeeper/data/myid添加数字1保存退出2 准备发射
#生成公钥私钥
ssh-keygen -t rsa
回车回车回车
cd /root/ls .ssh
能看到 id_rsa id_rsa.pub将你的 SSH 公钥添加到名为 zookeeper-1 的远程服务器上
ssh-copy-id zookeeper-1
yes
ssh-copy-id zookeeper-2
yes
ssh-copy-id zookeeper-3
yesscp -r /usr/zookeeper/ zookeeper-2:/usr/
scp -r /usr/zookeeper/ zookeeper-3:/usr/scp /etc/hosts zookeeper-2:/etc/
scp /etc/hosts zookeeper-3:/etc/scp /etc/profile zookeeper-2:/etc/
scp /etc/profile zookeeper-3:/etc/3 发射完毕
改zookeeper-2里面的配置
source /etc/profile 让刚发射的环境变量文件生效
vim /usr/zookeeper/data/myid 从zookeeper-1发射过来的刚才配的数字是1改称2
改zookeeper-3里面的配置
source /etc/profile
vim /usr/zookeeper/data/myid 从zookeeper-1发射过来的刚才配的数字是1改称3
再zookeeper-1 zookeeper-2 zookeeper-3 启动zookeeper
zkServer.sh start zkServer.sh start zkServer.sh start
zkServer.sh status zkServer.sh status zkServer.sh status
按顺序启动1，2，3 可以看到zookeeper-2是leader ，1,3 follower
---------------------------------------------------------------------------------------------------------------------------------
4 脚本
一台一台启动太麻烦搞个zookeeper启动关闭脚本
mkdir shell && cd shell && vim zookeeper-start-stop.sh
#!/bin/bash
##获取当前主机运行的zk进程的数量
# zookeeper主机名字不带后面的数字
zkpsnum=`ps -ef | grep zookeeper-root-server-zookeeper | grep -v grep|wc -l`
#判断进程数量
if [ $zkpsnum == 0 ];then#打印提示echo 'zk集群开始启动!'#使用for循环启动各个服务器for i in {1..3};do#远程登录服务器执行命令source /etc/profile;让环境变量生效ssh zookeeper-$i "source /etc/profile;zkServer.sh start"doneecho 'zk集群启动完毕!'echo 'zk集群状态如下:'#使用for循环查看状态for i in {1..3};do#远程登录服务器执行命令source /etc/profile;让环境变量生效ssh zookeeper-$i "source /etc/profile;zkServer.sh status"doneelseecho 'zk集群开始关闭!!!!!!!!!!!!!!!'#使用for循环查看状态for i in {1..3};do#远程登录服务器执行命令source /etc/profile;让环境变量生效ssh zookeeper-$i "source /etc/profile;zkServer.sh stop"doneecho 'zk集群关闭完毕!'
fichmod +x zookeeper-start-stop.sh
