Zookeeper cluster installation

1. Download

wget http://mirrors.cnnic.cn/apache/zookeeper/stable/zookeeper-3.4.8.tar.gz

2. Decompression

Mkdir/usr/local/zookeeper && tar zxvf zookeeper-3.4.8.tar.gz && mv zookeeper-3.4.8/*/usr/local/ Zookeeper * * RM-RF zookeeper-3.4.8

3. Create a configuration file

Zookeeper file Configuration Detailed

DataDir: Data Catalog

Datalogdir: Log Directory

ClientPort: Client Connection port

The time interval between Ticktime:zookeeper servers or between the client and server to maintain a heartbeat, that is, each ticktime time sends a heartbeat.

The Initlimit:zookeeper leader accepts the maximum number of heartbeat intervals that the client (Follower) can tolerate when initializing a connection. The client connection failed when the Zookeeper server has not received the return information of the client after 5 heartbeats (that is, ticktime) length. The total length of time is 5*2000=10 seconds.

Synclimit: Represents the length of the request and response time between Leader and Follower, and the maximum length of time to be over how many ticktime, the total length of time is 2*2000=4 seconds.

Server. A=B:C:D:

A is a number that indicates this is the first server;

B is the IP address of this server;

C represents the port where the server exchanges information with the Leader server in the cluster;

D means that in case the Leader server in the cluster is hung up, a port is needed to re-elect the new Leader, which is the port that the server communicates with when the election is executed.
