Linux安装Zookeeper

Linux安装Zookeeper

1、检测前置环境

①java环境检测

java -version
#输出以下内容，代表java没有安装或者没有配置快捷访问
command not found: java
1
2
3

可参考Linux安装JDK8,Linux安装JDK11进行java环境的搭建，安装的java版本>=jdk8，最好是jdk8，jdk11有可能不行

②maven环境检测

mvn -v
#输出以下内容，代表maven没有安装或者没有配置快捷访问
command not found: mvn
1

3

可参考Linux安装Maven进行maven安装

2、创建存储Zookeeper的目录

cd /usr/local/src
mkdir zookeeper-src && cd zookeeper-src
1
2

3、获取Zookeeper压缩包

Zookeeper下载网站,如果下面代码获取不了，可到该网站地址下载后，将压缩包上传到服务器

wget https://www.apache.org/dyn/closer.lua/zookeeper/zookeeper-3.7.1/apache-zookeeper-3.7.1-bin.tar.gz
1

4、解压压缩包

tar -xvf apache-zookeeper-3.7.1-bin.tar.gz
1

5、启动Zookeeper

进入到apache-zookeeper-3.7.1-bin的bin文件夹，查看启动脚本zkServer.sh

 cd apache-zookeeper-3.7.1-bin/bin
#启动
./zkServer.sh help
#初步启动会出现zoo.cfg文件缺少的情况
ZooKeeper JMX enabled by default
Using config: /usr/local/src/zookeeper-src/apache-zookeeper-3.7.1-bin/bin/../conf/zoo.cfg
grep: /usr/local/src/zookeeper-src/apache-zookeeper-3.7.1-bin/bin/../conf/zoo.cfg: No such file or directory
grep: /usr/local/src/zookeeper-src/apache-zookeeper-3.7.1-bin/bin/../conf/zoo.cfg: No such file or directory
mkdir: cannot create directory ‘’: No such file or directory
Usage: ./zkServer.sh [--config <conf-dir>] {start|start-foreground|stop|version|restart|status|print-cmd}

6、创建zoo.cfg文件

进入conf目录并拷贝zoo_sample.cfg，因为启动的时候会默认使用conf/zoo.cfg文 件，当然也可以指定启动文件

cp zoo_sample.cfg zoo.cfg
1

7、修改zoo.cfg文件

①先创建存储zookeeper数据的文件夹

mkdir -p /usr/local/src/zookeeper-src/apache-zookeeper-3.7.1-bin/data
1

②编辑zoo.cof文件

vim zoo.cof
#修改dataDir位置
dataDir=/usr/local/src/zookeeper-src/apache-zookeeper-3.7.1-bin/data

8、配置环境变量

vim /etc/profile

# 文件末尾增加如下配置
export ZOOKEEPER_HOME=/usr/local/src/zookeeper-src/apache-zookeeper-3.7.1-bin
export PATH=$PATH:$ZOOKEEPER_HOME/bin

# 让profile文件生效
source /etc/profile

9、再次启动Zookeeper

zkServer.sh start
#启动成功
ZooKeeper JMX enabled by default
Using config: /usr/local/src/zookeeper-src/apache-zookeeper-3.7.1-bin/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
#检测启动状态
zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /usr/local/src/zookeeper-src/apache-zookeeper-3.7.1-bin/bin/../conf/zoo.cfg
Client port found: 2181. Client address: localhost. Client SSL: false.
