一、单节点安装
1、下载解压
tar -zxvf zookeeper-3.4.6.tar.gz
2、创建配置文件
$ZOOKEEPER_HOME/conf/下创建zoo.cfg
配置
tickTime=2000
dataDir=/usr/local/soft/job/zookeeper-3.4.6/data
dataLogDir=/usr/local/soft/job/zookeeper-3.4.6/logs
clientPort=4180
data和logs目录需要手动创建，否则服务不能正常启动
客户端连接会报错：Will not attempt to authenticate using SASL
环境变量：
ZOOKEEPER_HOME=/usr/local/soft/job/zookeeper-3.4.6
export ZOOKEEPER_HOME
export PATH=${PATH}:${ZOOKEEPER_HOME}/bin
3、启动
./zkServer.sh start
4、客户端连接
./zkCli.sh -server localhost:4180
Connecting to localhost:4180

二、为分布式安装
1、创建环境目录
[root@localhost zookeeper-3.4.6]# mkdir zk1
[root@localhost zookeeper-3.4.6]# mkdir zk2
[root@localhost zookeeper-3.4.6]# mkdir zk3
2、创建myid文件
[root@localhost zookeeper-3.4.6]# echo "1" > ./zk1/myid
[root@localhost zookeeper-3.4.6]# echo "2" > ./zk2/myid
[root@localhost zookeeper-3.4.6]# echo "3" > ./zk3/myid
3、分别修改配置文件
修改：dataDir,clientPort
增加：集群的实例，server.X，”X”表示每个目录中的myid的值
[root@localhost conf]# vi zk1.cfg
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/usr/local/soft/job/zookeeper-3.4.6/zk1
clientPort=2181
server.1=192.168.137.105:2888:3888
server.2=192.168.137.105:2889:3889
server.3=192.168.137.105:2890:3890
[root@localhost conf]# vi zk2.cfg
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/usr/local/soft/job/zookeeper-3.4.6/zk2
clientPort=2182
server.1=192.168.137.105:2888:3888
server.2=192.168.137.105:2889:3889
server.3=192.168.137.105:2890:3890
[root@localhost conf]# vi zk3.cfg
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/usr/local/soft/job/zookeeper-3.4.6/zk3
clientPort=2183
server.1=192.168.137.105:2888:3888
server.2=192.168.137.105:2889:3889
server.3=192.168.137.105:2890:3890
4、启动
[root@localhost bin]# ./zkServer.sh start zk1.cfg
[root@localhost bin]# ./zkServer.sh start zk2.cfg
[root@localhost bin]# ./zkServer.sh start zk3.cfg
5、查看状态
[root@localhost bin]# jps
8130 Jps
7833 QuorumPeerMain
7805 QuorumPeerMain
7853 QuorumPeerMain
[root@localhost bin]# ./zkServer.sh status zk1.cfg
JMX enabled by default
Using config: /usr/local/soft/job/zookeeper-3.4.6/bin/../conf/zk1.cfg
Mode: follower
[root@localhost bin]# ./zkServer.sh status zk2.cfg
JMX enabled by default
Using config: /usr/local/soft/job/zookeeper-3.4.6/bin/../conf/zk2.cfg
Mode: leader
[root@localhost bin]# ./zkServer.sh status zk3.cfg
JMX enabled by default
Using config: /usr/local/soft/job/zookeeper-3.4.6/bin/../conf/zk3.cfg
Mode: follower
可以看到zk2是leader，zk1和zk3是follower
三、分布式安装
1、创建myid文件
Data目录下创建myid
分别写1,2,3
2、修改配置文件
tickTime=2000 dataDir=/usr/local/soft/job/zookeeper-3.4.6/data dataLogDir=/usr/local/soft/job/zookeeper-3.4.6/logs clientPort=4180 initLimit=10 syncLimit=5 server.1=192.168.137.105:2888:3888 server.2=192.168.137.106:2888:3888 server.3=192.168.137.107:2888:3888
3、启动
zkServer.sh start
4、连接
zkCli.sh -server 192.168.137.107:4180
5、查看状态
jps
四、操作
