搭建zookeeper集群 亲测有效 避免走坑
一．准备工作：
## 开启指定端口
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
## 重启防火墙
systemctl restart firewalld.service
## 查看端口是否成功开启
firewall-cmd --list-ports
打开页面
https://archive.apache.org/dist/zookeeper/zookeeper-3.4.6/
下载
https://archive.apache.org/dist/zookeeper/zookeeper-3.4.6/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 另外两台机器分别echo "2" > myid echo "3" > myid
1对应zoo.cfg配置中server.1 中的1
- 搭建zookeeper集群
cd /home/test/zookeeper/conf
cp zoo_sample.cfg zoo.cfg
三个zoo.cfg配置本机用节点时 用 0.0.0.0 IP代替主机名 其余部分配置一样
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.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# 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=第二台外网IP:12888:13888
server.3=第三台外网IP:12888:13888
第二台：
server.1=第一台外网IP:12888:13888
server.2=0.0.0.0:12888:13888
server.3=第三台外网IP:12888:13888
第三台：
server.1=第一台外网IP:12888:13888
server.2=第二台外网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
此时
telnet 机器ip 12181
telnet 机器ip 12888
telnet 机器ip 13888
发现都通了
