zookeeper 2.4.6安装
准备工作
- zookeeper安装包zookeeper-3.4.6.tar.gz
- s0,s1,s2 三台服务器配置zookeeper环境
- 先在s0配置好,在把配置文件夹同步 $ZOOKEEPER_HOME/conf
- 每台机器要单独启动,关闭
操作步骤
解压压缩包
tar -zxvf /opt/modules/bigdata/zookeeper/zookeeper-3.4.6.tar.gz -C /opt/modules/bigdata/zookeeper 即 $ZOOKEEPER_HOME=/opt/modules/bigdata/zookeeper/zookeeper-3.4.6
复制文件 $ZOOKEEPER_HOME/conf/zoo_sample.cfg 为 $ZOOKEEPER_HOME/conf/zoo.cfg 增加内容
dataDir=/opt/modules/bigdata/zookeeper/zookeeper-3.4.6/data dataLogDir=/opt/modules/bigdata/zookeeper/zookeeper-3.4.6/logs server.0=s0:2888:3888 server.1=s1:2888:3888 server.2=s2:2888:3888
- 新建目录logs ==> $ZOOKEEPER_HOME/logs
- 新建目录data ==> $ZOOKEEPER_HOME/data
增加文件myid ==> $ZOOKEEPER_HOME/data/myid
myid s0内容为: 0 myid s1内容为: 1 myid s2内容为: 2
命令
- 需要分别启动,停止每一台机器
- ).启动 zookeeper: /opt/modules/bigdata/zookeeper/zookeeper-3.4.6/bin/zkServer.sh start
- ).停止 zookeeper: /opt/modules/bigdata/zookeeper/zookeeper-3.4.6/bin/zkServer.sh stop
- ).状态 zookeeper: /opt/modules/bigdata/zookeeper/zookeeper-3.4.6/bin/zkServer.sh status
jps 验证
s0,s1,s2 每台机器都有进程:QuorumPeerMain
