学电商一般月收入多少优化搜索曝光次数的方法

安装

下载地址：Apache ZooKeeper

我下载的版本：zookeeper-3.4.12

下载后，解压

配置

1、 在D:\zookeeper-3.4.12文件夹中创建一个“data”文件夹和“log”文件夹

2、 复制zoo_sample.cfg，改名：zoo.cfg

修改zoo.cfg文件

# 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.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
#dataDir=/tmp/zookeeper
dataDir=D:\zookeeper-3.4.12\data
dataLogDir=D:\zookeeper-3.4.12\log
# the port at which the clients will connect
clientPort=2181

启动

进入目录：D:\zookeeper-3.4.12\bin

1、执行zkServer.cmd

2、执行zkCli.cmd

#连接本地zk
zkCli.cmd#链接远程zk
zkCli.cmd -server ip:port

简单用法

在zkCli.cmd上操作

1. 创建节点

 create /test "my_data"

节点：/test

值：my_data

注意：在zk创建节点，必须要以"/"开头，否则会报错：Command failed: java.lang.IllegalArgumentException: Path must start with / character

2. 获取节点

get /test

3. 修改节点

 set /test "abc"

4. 创建子节点

create /test/child "child"

5. 查看子节点

ls /test

6. 删除节点

delete /test/child
