1.基本信息
| 版本 | 3.4.6 |
|---|---|
| 安装机器 | 三台机器 |
| 账号 | hadoop |
| 源路径 | /opt/software/zookeeper-3.4.6.tar.gz |
| 目标路径 | /opt/zookeeper -> /opt/zookeeper-3.4.6/ |
| 依赖关系 | 无 |
2.安装过程
1).使用hadoop账户，通过tar -xxvf命令将zookeeper-${version}.tar.gz解压缩至目的安装目录,并设置软连接。
[root @bgs -5p173-wangwenting opt]# su hadoop [hadoop @bgs -5p173-wangwenting opt]$ cd /opt/software [hadoop @bgs -5p173-wangwenting software]$ tar -zxvf zookeeper-${version}.tar.gz -C /opt/ [hadoop @bgs -5p173-wangwenting software]$ cd /opt/ [hadoop @bgs -5p173-wangwenting opt]$ ln -s /opt/zookeeper-${version} /opt/zookeeper |
修改zoo.cfg配置文件。
[hadoop @bgs -5p173-wangwenting zookeeper]# cd /opt/zookeeper/conf [hadoop @bgs -5p173-wangwenting conf]$ cp zoo_sample.cfg zoo.cfg [hadoop @bgs -5p173-wangwenting conf]$ vim zoo.cfg |
2).在zoo.cfg文件中添加如下配置：
dataDir=/opt/zookeeper/data dataLogDir=/opt/zookeeper/log server. 1 =bgs-5p173-wangwenting: 2888 : 3888 server. 2 =bgs-5p174-wangwenting: 2888 : 3888 server. 3 =bgs-5p175-wangwenting: 2888 : 3888 |
3).创建data目录和log目录，并在data目录下创建文件，命名为myid：
[hadoop @bgs -5p173-wangwenting conf]$ mkdir /opt/zookeeper/data [hadoop @bgs -5p173-wangwenting conf]$ mkdir /opt/zookeeper/log [hadoop @bgs -5p173-wangwenting conf]$ vim /opt/zookeeper/data/myid 在myid文件中写入 1 （同理在另外两台机器中写 2 和 3 ） 1 |
4).配置zookeeper运行的环境变量。
[hadoop @bgs -5p173-wangwenting conf]$ vim /etc/profile 添加下面的内容： export ZK_HOME=/opt/hadoop/zookeeper export PATH=$ZK_HOME/bin:$PATH 配置成功后，执行source /etc/profile使配置生效 [hadoop @bgs -5p173-wangwenting conf]$ source /etc/profile |
5).将安装包从bgs-5p173-wangwenting服务器复制到bgs-5p174-wangwenting，bgs-5p175-wangwenting两台机器，并配置环境变量：
[hadoop @bgs -5p173-wangwenting conf]$ scp -r /opt/zookeeper- 3.4 . 6 hadoop @bgs -5p174-wangwenting:/opt [hadoop @bgs -5p173-wangwenting conf]$ scp -r /opt/zookeeper- 3.4 . 6 hadoop @bgs -5p175-wangwenting:/opt |
在bgs-5p174-wangwenting和bgs-5p175-wangwenting上分别执行
[hadoop @bgs -5p174-wangwenting conf]$ ln -s /opt/zookeeper- 3.4 . 6 /opt/zookeeper [hadoop @bgs -5p175-wangwenting conf]$ ln -s /opt/zookeeper- 3.4 . 6 /opt/zookeeper |
在bgs-5p174-wangwenting和bgs-5p175-wangwenting上分别修改/opt/zookeeper/data/myid文件，bgs-5p174-wangwenting中的myid改为2bgs-5p175-wangwenting中的改为3
[hadoop @bgs -5p174-wangwenting conf]$ vim /opt/zookeeper/data/myid 2 [hadoop @bgs -5p175-wangwenting conf]$ vim /opt/zookeeper/data/myid 3 |
在bgs-5p174-wangwenting和bgs-5p175-wangwenting上分别步骤4配置zookeeper运行的环境变量
6).在三台机器上分别执行zookeeper命令：$ zkServer.sh start
[hadoop @bgs -5p173-wangwenting conf]$ zkServer.sh start [hadoop @bgs -5p174-wangwenting conf]$ zkServer.sh start [hadoop @bgs -5p175-wangwenting conf]$ zkServer.sh start |
7).检查每台机器的zookeeper状态：$ zkServer.sh status
若输出结果是leader 或者follower, 三台机器中有一台是leader 和2 个follower, 说明安装成功了。
[hadoop @bgs -5p173-wangwenting conf]$ zkServer.sh status [hadoop @bgs -5p174-wangwenting conf]$ zkServer.sh status [hadoop @bgs -5p175-wangwenting conf]$ zkServer.sh status |
8).检查zkCli命令是否能够执行成功：
[hadoop @bgs -5p173-wangwenting conf]$ zkCli.sh -server bgs-5p173-wangwenting: 2181 ,bgs-5p174-wangwenting: 2181 ,bgs-5p175-wangwenting: 2181 |
若能成功连接，说明安装启动成功了
