zookeeper单机部署

安装zookeeper并配置环境变量

首先需要安装jdk环境，这里不在述说

wget https://archive.apache.org/dist/zookeeper/zookeeper-3.7.0/apache-zookeeper-3.7.0-bin.tar.gz
tar -xf apache-zookeeper-3.7.0-bin.tar.gz -C /usr/local/
cd /usr/local/
mv apache-zookeeper-3.7.0-bin/ zookeeper
vim /etc/profile
PATH=$PATH:/usr/local/zookeeper/bin
source /etc/profile

配置zookeeper服务

cd /usr/local/zookeeper/conf/
cp zoo_sample.cfg zoo.cfg
vim zoo.cfg
dataDir=/data/zookeeper
mkdir /data/zookeeper -p

管理zookeeper服务

启动zookeeper

zkServer.sh start
/usr/local/jdk/bin/java
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED


zkServer.sh status
/usr/local/jdk/bin/java
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Client port found: 2181. Client address: localhost. Client SSL: false.
Mode: standalone


ll /data/zookeeper/
total 4
drwxr-xr-x. 2 root root 24 Jul 16 09:55 version-2
-rw-r--r--. 1 root root  4 Jul 16 09:55 zookeeper_server.pid

使用"zkCli.sh"工具连接zookeeper服务

zkCli.sh
