一．準備工作：
## 開啟指定埠
firewall-cmd --zone=public --add-port=12181/tcp --permanent
firewall-cmd --zone=public --add-port=12888/tcp --permanent
firewall-cmd --zone=public --add-port=13888/tcp --permanent
systemctl restart firewalld.service
## 重啟防火牆
systemctl restart firewalld.service
## 檢視埠是否成功開啟
firewall-cmd --list-ports
開啟頁面
zookeeper-3.4.6.tar.gz
cd /home/test/
tar -zxvf zookeeper-3.4.6.tar.gz
mv zookeeper-3.4.6.tar.gz zookeeper
cd/home/test/zookeeper
mkdir /home/test/zookeeper/zkdata -p
mkdir /home/test/zookeeper/zkdatalog -p
cd /home/test/zookeeper/zkdata
echo "1" > myid 另外兩台機器分別echo "2" > myid echo "3" > myid
1對應zoo.cfg配置中server.1中的1
cd /home/test/zookeeper/conf
cp zoo_sample.cfg zoo.cfg
三個zoo.cfg配置本機用節點時用 0.0.0.0 ip代替主機名其餘部分配置一樣
vim zoo.cfg
# the number of milliseconds of each tick
ticktime=2000
# the number of ticks that the initial
# synchronization phase can take
initlimit=10
# the number of ticks that can pass between
# sending a request and getting an acknowledgement
synclimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
datadir=/home/test/zookeeper/zkdata
datalogdir=/home/test/zookeeper/zkdatalog
# the port at which the clients will connect
clientport=12181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxclientcnxns=60
#
# be sure to read the maintenance section of the
# administrator guide before turning on autopurge.
#
#
#
# the number of snapshots to retain in datadir
#autopurge.snapretaincount=3
# purge task interval in hours
# set to "0" to disable auto purge feature
#autopurge.purgeinterval=1
#第一台：
server.1=0.0.0.0:12888:13888
server.2=第二台外網ip:12888:13888
server.3=第三台外網ip:12888:13888
第二台：
server.1=第一台外網ip:12888:13888
server.2=0.0.0.0:12888:13888
server.3=第三台外網ip:12888:13888
第三台：
server.1=第一台外網ip:12888:13888
server.2=第二台外網ip:12888:13888
server.3=0.0.0.0:12888:13888
cd /home/test/zookeeper/bin
sh zkserver.sh start
sh zkserver.sh status 看到mode: leader 或者 mode: follower 表示集群搭建成功
jps
此時
telnet 機器ip 12181
telnet 機器ip 12888
telnet 機器ip 13888
發現都通了
zookeeper集群搭建
接觸zookeeper集群已有很長很長一段時間了，zookeeper在專案中的使用相當的頻繁，如dubb服務 amq集群 大資料領域hadoop等。zookeeper的集群建立非常簡單，一直想寫一篇文章來對集群使用的介紹，但一直沒能抽出空，今天正好閒來無事，就重新實踐一遍來整理記錄，下文是基本的集群...
