linux安装zookeeper

服务器：阿里云

zookeeper:3.4.11

================================================================================================

1，安装jdk1.8(不做叙述)

2，安装zookeeper

步骤：

1，在zookeeper官网下载zookeeper

2，上传到linux服务器上

3，解压zookeeper

4，把zookeeper文件夹转移到/usr/local下（一般安装文件都会移动到这个目录）

5，添加环境变量（包括了jdk的环境变量和zookeeper的）

export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE HISTCONTROL
export JAVA_HOME=/usr/local/jdk8
export ZOOKEEPER_HOME=/usr/local/zookeeper

export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$JAVA_HOME/bin:$ZOOKEEPER_HOME/bin:$PATH

6，进入zookeeper的目录，进入conf下找到zoo_sample.cfg，复制该文件名为zoo.cfg

7，进入zoo.cfg，修改dataDir=/tmp/zookeeper

改为

dataDir=/usr/local/zookeeper/dataDir
dataLogDir=/usr/local/zookeeper/dataLogDir

8，进入对应的目录下新建7步骤的两个文件夹

9，进入bin目录，找到zkServer.sh

输入命令　　zkServer.sh start　　　　启动zookeeper

　　　　　　zkServer.sh stop　　　　停止zookeeper

　　　　　　zkServer.sh restart　　　重启zookeeper
