源码安装至/usr/local/zookeeper

配置 /usr/local/zookeeper/conf/zoo.cfg

server.1=node1:2888:3888server.2=node2:2888:3888server.3=node3:2888:3888server.4=nn01:2888:3888:observer

拷贝安装目录至所有集群主机

rsync -aSH --delete /usr/local/zookeeper node1:/usr/local/...

 

创建myid文件，id必须与配置文件里主机名对应的server.(id)一致

[root@nn01 local]# echo 4 > /tmp/zookeeper/myid[root@nn01 local]# ssh node3 'echo 3 >/tmp/zookeeper/myid'[root@nn01 local]# ssh node2 'echo 2 >/tmp/zookeeper/myid'[root@nn01 local]# ssh node1 'echo 1 >/tmp/zookeeper/myid'

 

所有集群主机启动服务

/usr/local/zookeeper/bin/zkServer.sh start  /usr/local/zookeeper/bin/zkServer.sh status # 查看状态

 

确认主机状态

[root@nn01 local]# echo 'ruok' | socat - TCP:node3:2181imok[root@nn01 local]#

　[root@nn01 local]# echo 'stat' | socat - TCP:node3:2181　　

脚本

#!/bin/bashfunction get_zkstat(){    exec 2/dev/tcp/$1/2181    echo "stat" >&8    _S=$(cat <&8|grep -Po "^Mode:.*")    echo -e "$1\t${_S:-Mode: NULL}"    exec 8<&-}if (( $# == 0 ));then   echo "Usage: $0 host1 host2 host3 ... ..."else   for i in $@;do get_zkstat ${i};donefi
