【zookeeper】--部署3.6.3

下载解压

wget https://archive.apache.org/dist/zookeeper/zookeeper-3.6.3/apache-zookeeper-3.6.3-bin.tar.gz
tar -zxvf zookeeper-3.6.3-bin.tar.gz -C XXXX

创建data和logs

cd XXXX
mkdir data logs

配置文件

1)创建目录并且编辑 zoo.cfg

[root@node01 apache-zookeeper-3.6.3-bin]# cp conf/zoo_sample.cfg conf/zoo.cfg
[root@node01 apache-zookeeper-3.6.3-bin]# vim conf/zoo.cfg# 修改以下内容 （旁边的数字是行号）
dataDir=XXXX/data
dataLogDir=XXXX/logs
clientPort=2181
server.1=node01:2888:3888
server.2=node02:2888:3888
server.3=node03:2888:3888

2)接下来将 node01 的 ZooKeeper 所有文件拷贝至 node02 和 node03。推荐从 node02 和 node03 拷贝

[root@node01 ~]# scp -r /opt/yjx/apache-zookeeper-3.6.3-bin/ node02:$PWD
[root@node01 ~]# scp -r /opt/yjx/apache-zookeeper-3.6.3-bin/ node03:$PWD

3）在三台节点 /var/yjx/zookeeper/data 目录下分别创建 myid 文件，内容分别为 1，2，3。

node01`在这里插入代码片`
[root@node01 ~]# echo 1 > /var/yjx/zookeeper/data/myidnode02
[root@node02 ~]# mkdir -p /var/yjx/zookeeper/data
[root@node02 ~]# echo 2 > /var/yjx/zookeeper/data/myidnode03
[root@node03 ~]# mkdir -p /var/yjx/zookeeper/data
[root@node03 ~]# echo 3 > /var/yjx/zookeeper/data/myid#！注意 确定每一个myid只有一行并且没有多余空格

4）最后 vim /etc/profile 配置环境变量，环境搭建结束。配完环境变量后 source /etc/profile 重新加载环境变量。

[root@node01 ~]# vim /etc/profileexport ZOOKEEPER_HOME=/opt/yjx/apache-zookeeper-3.6.3-bin
export PATH=$ZOOKEEPER_HOME/bin:$PATH[root@node01 ~]# source /etc/profile

启动

[root@node01 ~]# zkServer.sh start
[root@node02 ~]# zkServer.sh start
[root@node03 ~]# zkServer.sh start

启动脚本

# 在 /usr/local/bin 目录下创建对应服务的脚本：
[root@node01 ~]# cd ~
[root@node01 ~]# vim zookeeper..............................................................
#!/bin/bashuser=$(whoami)
