ubuntu 安装zookeeper和设置开机启动

1. 安装：

sudo?apt-get?install?zookeeper

默认信息：

#安装路径
/usr/share/zookeeper
#配置文件
/etc/zookeeper/conf/zoo.cfg

2. 启动zookeeper

cd?/usr/share/zookeeper/bin
sudo?sh?zkServer.sh?start

ZooKeeper?JMX?enabled?by?default
Using?config:?/etc/zookeeper/conf/zoo.cfg
Starting?zookeeper?...?STARTED

启动zookeeper时遇到错误以下错误

zkServer.sh:?157:?zkServer.sh:?Syntax?error:?"("?unexpected?(expecting?";;")
原因是：zookeeper使用的shell版本和系统使用的shell版本不兼容，当前ubuntu系统的shell默认使用的是dash,而zookeeper使用的是bash
解决办法：
dpkg-reconfigure?dash
Tab?移动到NO(选择否)?回车即可

验证是否启动成功

/usr/share/zookeeper/bin$?sudo?zkCli.sh?-server?localhost:2181

Connecting?to?localhost:2181
Welcome?to?ZooKeeper!
JLine?support?is?enabled

WATCHER::

WatchedEvent?state:SyncConnected?type:None?path:null

zookeeper基本操作

• 启动ZK服务: sh bin/zkServer.sh start

• 查看ZK服务状态: sh bin/zkServer.sh status

• 停止ZK服务: sh bin/zkServer.sh stop

• 重启ZK服务: sh bin/zkServer.sh restart?

3. 设置开机启动

3.1 配置文件

sudo?vim?/etc/init.d/zookeeper

添加以下信息，注意自己的相关路径是否相同，不同修改之

!/bin/sh
#Configurations?injected?by?install_server?below....
EXEC=/usr/share/zookeeper/bin/zkServer.sh
ZOO_LOG_DIR="/var/zookeeper"
JAVA_HOME=/usr/hisen/soft/jdk8?
PATH=${JAVA_HOME}/bin:$PATH
