安裝 ZooKeeper 單機版

建議閱讀我之前發布的筆記：

CentOS 6學習筆記（六）–CentOS6環境安裝ZooKeeper

搭建 ZooKeeper 集群

本筆記通過在單臺服務器上運行 3 個 ZooKeeper 實例的方式來模擬 ZooKeeper 集群。

本篇筆記是為后續搭建 SolrCloud 做準備。

創建 ZooKeeper 實例

mkdir /usr/local/solr-cloud
cp -r zookeeper-3.4.6 /usr/local/solr-cloud/zookeeper01
cp -r zookeeper-3.4.6 /usr/local/solr-cloud/zookeeper02
cp -r zookeeper-3.4.6 /usr/local/solr-cloud/zookeeper03

配置 ZooKeeper 實例

配置實例 1

cd /usr/local/solr-cloud/zookeeper01
mkdir data
cd /usr/local/solr-cloud/zookeeper01/data
echo 1 >myid
cd /usr/local/solr-cloud/zookeeper01/conf
cp zoo_sample.cfg zoo.cfg
vim zoo.cfg

在 zoo.cfg 配置以下內容

dataDir=/usr/local/solr-cloud/zookeeper01/data
#ZooKeeper提供服務的端口
clientPort=2181
#2881 2882 2883是節點之間內部通信的端口
#3881 3882 3883是節點之間投票選舉的端口
server.1=192.168.25.155:2881:3881
server.2=192.168.25.155:2882:3882
server.3=192.168.25.155:2883:3883

配置實例 2

cd /usr/local/solr-cloud/zookeeper02
mkdir data
cd /usr/local/solr-cloud/zookeeper02/data
echo 2 >myid
cd /usr/local/solr-cloud/zookeeper02/conf
cp zoo_sample.cfg zoo.cfg
vim zoo.cfg

在 zoo.cfg 配置以下內容

dataDir=/usr/local/solr-cloud/zookeeper02/data

clientPort=2182

server.1=192.168.25.155:2881:3881
server.2=192.168.25.155:2882:3882
server.3=192.168.25.155:2883:3883

配置實例 3

cd /usr/local/solr-cloud/zookeeper03
mkdir data
cd /usr/local/solr-cloud/zookeeper03/data
echo 3 >myid
cd /usr/local/solr-cloud/zookeeper03/conf
cp zoo_sample.cfg zoo.cfg
vim zoo.cfg

在 zoo.cfg 配置以下內容

dataDir=/usr/local/solr-cloud/zookeeper03/data

clientPort=2183

server.1=192.168.25.155:2881:3881
server.2=192.168.25.155:2882:3882
server.3=192.168.25.155:2883:3883

使用

編寫腳本文件啟動 ZooKeeper 集群

vim /usr/local/solr-cloud/start-zk-all.sh

cd /usr/local/solr-cloud/zookeeper01/bin
./zkServer.sh start
cd /usr/local/solr-cloud/zookeeper02/bin
./zkServer.sh start
cd /usr/local/solr-cloud/zookeeper03/bin
./zkServer.sh start

修改權限

cd /usr/local/solr-cloud
chmod u+x start-zk-all.sh

開啟 ZooKeeper 集群

/usr/local/solr-cloud/start-zk-all.sh

查看狀態

/usr/local/solr-cloud/zookeeper01/bin/zkServer.sh status
/usr/local/solr-cloud/zookeeper02/bin/zkServer.sh status
/usr/local/solr-cloud/zookeeper03/bin/zkServer.sh status

編寫腳本文件關閉 ZooKeeper 集群

vim /usr/local/solr-cloud/shutdown-zk-all.sh

cd /usr/local/solr-cloud/zookeeper01/bin
./zkServer.sh stop
cd /usr/local/solr-cloud/zookeeper02/bin
./zkServer.sh stop
cd /usr/local/solr-cloud/zookeeper03/bin
./zkServer.sh stop

修改權限

cd /usr/local/solr-cloud
chmod u+x shutdown-zk-all.sh

關閉 ZooKeeper 集群

/usr/local/solr-cloud/shutdown-zk-all.sh

維護指令總結

#開啟 ZooKeeper 集群
/usr/local/solr-cloud/start-zk-all.sh
#查看狀態
/usr/local/solr-cloud/zookeeper01/bin/zkServer.sh status
/usr/local/solr-cloud/zookeeper02/bin/zkServer.sh status
/usr/local/solr-cloud/zookeeper03/bin/zkServer.sh status
#關閉 ZooKeeper 集群
/usr/local/solr-cloud/shutdown-zk-all.sh

開機自啟

vim /etc/rc.d/rc.local

添加

/usr/local/solr-cloud/start-zk-all.sh
