源码安装

安装

mkdir -p /opt/{install/zookeeper/data,package/zookeeper}
cd /opt/package/zookeeper
wget https://dlcdn.apache.org/zookeeper/zookeeper-3.6.3/apache-zookeeper-3.6.3-bin.tar.gz
tar xf apache-zookeeper-3.6.3-bin.tar.gz

cd apache-zookeeper-3.6.3-bin/conf/
cp zoo_sample.cfg zoo.cfg
vi zoo.cfg
# 修改dataDir目录
dataDir=/opt/install/zookeeper/data

# 设置环境变量
vi /etc/profile
# ZooKeeper
export ZOOKEEPER_HOME=/opt/package/zookeeper/apache-zookeeper-3.6.3-bin
export PATH=${ZOOKEEPER_HOME}/bin:$PATH
# 让修改生效：. 或者 source
. /etc/profile

集群安装

准备4台主机

• 172.16.2.91
• 172.16.2.92
• 172.16.2.93
• 172.16.2.94

1. 创建基础目录(4台)

mkdir -p /opt/{install/zookeeper/data,package/zookeeper}

2. 172.16.2.91执行

cd /opt/package/zookeeper
wget https://dlcdn.apache.org/zookeeper/zookeeper-3.6.3/apache-zookeeper-3.6.3-bin.tar.gz
tar xf apache-zookeeper-3.6.3-bin.tar.gz

# 修改配置文件 zoo.cfg
cd apache-zookeeper-3.6.3-bin/conf/
cp zoo_sample.cfg zoo.cfg
vi zoo.cfg
---
dataDir=/etc/install/zookeeper/data

server.1=172.16.2.91:2888:3888
server.2=172.16.2.92:2888:3888
server.3=172.16.2.93:2888:3888
server.4=172.16.2.94:2888:3888
---

# 拷贝到其它三台主机
scp -r /opt/package/zookeeper/apache-zookeeper-3.6.3-bin/ 172.16.2.92:`pwd`
scp -r /opt/package/zookeeper/apache-zookeeper-3.6.3-bin/ 172.16.2.93:`pwd`
scp -r /opt/package/zookeeper/apache-zookeeper-3.6.3-bin/ 172.16.2.94:`pwd`

3. 在dataDir目录下添加myid(4台)

echo 1 > /opt/install/zookeeper/data/myid
echo 2 > /opt/install/zookeeper/data/myid
echo 3 > /opt/install/zookeeper/data/myid
echo 4 > /opt/install/zookeeper/data/myid

4. 设置环境变量(4台)

vi /etc/profile
# ZooKeeper
export ZOOKEEPER_HOME=/opt/package/zookeeper/apache-zookeeper-3.6.3-bin
export PATH=${ZOOKEEPER_HOME}/bin:$PATH
# 让修改生效：. 或者 source
. /etc/profile

启动服务端、客户端

zkServer.sh help
# 前台启动（start默认后台启动）
zkServer.sh start-foreground
# 启动客户端
zkCli.sh
