contos7 安装zookeeper集群

1.软件版本：

zookeeper-3.4.6.tar.gz

2.下载地址:

https://mirrors.cnnic.cn/apache/zookeeper/

3.上传到机器目录：/usr/local

4.进入上传的目录后解压zookeeper：

tar -zxvf  zookeeper-3.4.6.tar.gz  zookeeper

# 进入zookeeper目录
cd zoookeeper/

# 创建data 和 logs目录
mkdir data logs

 

5.在 data 目录下创建 myid 文件，并写入编号

?

1 2 3

cd ../data touch myid echo "1">>myid

　　每台机器的myid里面的值对应server.后面的数字x。

 

6.需要开放3个端口（可选做）

?

1 2 3

[root@redhat66 data]# sudo /sbin/iptables -I INPUT -p tcp --dport 2181 -j ACCEPT [root@redhat66 data]# sudo /sbin/iptables -I INPUT -p tcp --dport 2888 -j ACCEPT [root@redhat66 data]# sudo /sbin/iptables -I INPUT -p tcp --dport 3888 -j ACCEPT

7.配置zookeeper环境变量

?

1 2 3 4 5 6 7 8 9 10

# 编辑 /etc/profile [root@192 ~]# vi /etc/profile   # 在文件尾部新增如下内容： #zookeeper export ZOOKEEPER_HOME=/usr/local/zookeeper export PATH=$ZOOKEEPER_HOME/bin/:$PATH   # 使文件生效 source /etc/profile

　8.配置zookeeper启动文件

?

1 2 3 4 5 6 7 8

# 进入conf cd conf/   # 拷贝文件 cp zoo_sample.cfg  zoo.cfg   # 编辑 vim zoo.cfg

　　全部配置如下：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34

# 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=/usr/local/zookeeper/data dataLogDir=/usr/local/zookeeper/logs/ server.1=192.168.0.165:2888:3888 server.2=192.168.0.166:2888:3888 server.3=192.168.0.167:2888:3888     # the port at which the clients will connect clientPort=2181 # 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

　　server.x  x与myid文件中的内容保持一致

9.其他的机器重复步骤3-8步骤

10.分别启动三台机器上的zookeeper服务

?

1	zkServer.sh start

11.查看服务状态

?

1	zkServer.sh status<br><br>

[root@192 bin]# zkServer.sh status
JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Mode: follower

 

 

[root@redhat66 bin]# zkServer.sh status
JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Mode: leader

 

 

[root@192 bin]# ./zkServer.sh status
JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Mode: follower

 

12.或者使用jps，有（4895 QuorumPeerMain）则启动成功

 

?

1 2 3

[root@192 bin]# jps 4922 Jps 4895 QuorumPeerMain

　　

 

13.客户端连接

?

1	./zkCli.sh -server 192.168.0.166:2181
