2.2 配置
2.2.1 环境变量配置
vim ~/.bash_profile
export ZOOKEEPER_HOME=/usr/local/zookeeper
export PATH=.:$JAVA_HOME/bin:$ZOOKEEPER_HOME/bin:$KAFKA_HOME/bin:$PATH
source ~/.bash_profile
3.运行配置
3.1 单机模式配置
进入zookeeper配置目录，cd /usr/local/zookeeper/conf
复制添加zoo.cfg配置文件 cp zoo.sample.cfg zoo.cfg
编辑zoo.cfg
# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
dataDir=/tmp/zookeeper
# the port at which the clients will connect
clientPort=2181
【参数说明】
tickTime: zookeeper中使用的基本时间单位, 毫秒值.
dataDir: 数据目录. 可以是任意目录.
dataLogDir: log目录, 同样可以是任意目录. 如果没有设置该参数, 将使用和dataDir相同的设置.
clientPort: 监听client连接的端口号.
至此, zookeeper的单机模式已经配置好了. 启动server只需运行脚本:
./bin/zkServer.sh start
Server启动之后, 就可以启动client连接server了, 执行脚本:
./bin/zkCli.sh -server localhost:2181
