contos7 安裝zookeeper集群

1.軟件版本：

zookeeper-3.4.6.tar.gz

2.下載地址:

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

3.上傳到機器目錄：/usr/local

4.進入上傳的目錄后解壓zookeeper：

tar -zxvf  zookeeper-3.4.6.tar.gz  zookeeper

# 進入zookeeper目錄
cd zoookeeper/

# 創(chuàng)建data 和 logs目錄
mkdir data logs

5.在 data 目錄下創(chuàng)建 myid 文件，并寫入編號

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

　　每臺機器的myid里面的值對應server.后面的數字x。

6.需要開放3個端口（可選做）

[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環(huán)境變量

# 編輯 /etc/profile
[root@192 ~]# vi /etc/profile

# 在文件尾部新增如下內容：
#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啟動文件

# 進入conf
cd conf/

# 拷貝文件
cp zoo_sample.cfg  zoo.cfg

# 編輯
vim zoo.cfg

　　全部配置如下：

# 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與myid文件中的內容保持一致

9.其他的機器重復步驟3-8步驟

10.分別啟動三臺機器上的zookeeper服務

zkServer.sh start

11.查看服務狀態(tài)

zkServer.sh status

[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）則啟動成功

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

13.客戶端連接

./zkCli.sh -server 192.168.0.166:2181
