Linux_Ubuntu_安装zookeeper

1. 下载zookeeper，http://archive.apache.org/dist/zookeeper/

2. 解压到: /opt/zookeeper-3.4.6下载

3. 把conf下的zoo_sample.cfg copy一份后重命名为: zoo.cfg.

    文件中内容如下:
    syncLimit=5
    initLimit=10
    tickTime=2000
    clientPort=2181
    dataDir=/opt/zookeeper-3.4.6/data
    dataLogDir=/opt/zookeeper-3.4.6/logs

4. 新建zookeeper-3.4.6下的data,log目录,然后

    chmod u+x /opt/zookeeper-3.4.6/bin/*

5. 新建shell脚本startZookeeper.sh在/opt/shell文件夹下，

    chmod u+x /opt/shell/startZookeeper.sh

   内容：

    #!/bin/sh
    #to start zookeeper
    #set environment
    export ZOOKEEPER_INSTALL=/opt/zookeeper-3.4.6
    export PATH=$PATH:$ZOOKEEPER_INSTALL/bin
    PID_FILE=$ZOOKEEPER_INSTALL/data/zookeeper_server.pid
    FLAG=$1
   
    if [ "$FLAG" = "os_start" ] && [ -f "$PID_FILE" ]
    then
            rm $PID_FILE
    fi
   
    #start zookeeper
    $ZOOKEEPER_INSTALL/bin/zkServer.sh start

6. 设置zookeeper开机启动

    vim /etc/rc.local
    在最后一行添加如下两句话
    #start zookeeper
    /opt/shell/startZookeeper.sh
