Manual configuration of Zookeeper in Ubuntu environment

Configure Zookeeper

Note: Because it is a single-machine pseudo-distributed configuration, there are 3 servers on the same

The zookeeper file format is as follows

Home---Zookeeper---server0---zookeeper                    |                    ------------Server1---zookeeper                    |                    ------------Server2---Zookeeper

1. Download Zookeeper(I'm using: zookeeper-3.4.6.tar.gz)

Unzip separately to/home/zookeeper/server0

/home/zookeeper/server1

/home/zookeeper/server2

2. Folder settings

Generate logs and data folders under Zookeeper in 3 servers, respectively

sudo mkdir datasudo mkdir logs//must be in the Zookeeper folder of each server

Generate myID files under Zookeeper/data in 3 servers, respectively, and write 0,1,2 in open files (Server0 write 0,server1 write in 1,server2 2)

sudo gedit myid//generates myID files and must be in the Data folder

3. Configure Zoo.cfg(Configure the time, note the datadir of the following address do not bring unnecessary strings!!!) Like a space or something. ）

In the Zookeeper/conf folder, Sir, into this empty file.

sudo gedit zoo.cfg//must be under the Conf folder

Server0 in zoo.cfg fill in the content

Server1 in zoo.cfg fill in the content

ticktime=2000initlimit=5synclimit=2datadir=/home/zookeeper/server1/zookeeper/datadatalogdir=/home/zookeeper/ Server1/zookeeper/logsclientport=2182server.0=127.0.0.1:8880:7770server.1=127.0.0.1:8881:7771server.2= 127.0.0.1:8882:7772

Server2 in zoo.cfg fill in the content

ticktime=2000initlimit=5synclimit=2datadir=/home/zookeeper/server2/zookeeper/datadatalogdir=/home/zookeeper/ Server2/zookeeper/logsclientport=2182server.0=127.0.0.1:8880:7770server.1=127.0.0.1:8881:7771server.2= 127.0.0.1:8882:7772

4. Start all clusters of servers

Enter the/bin folder for each of the three servers:

sudo./zkserver.sh start  

5. Access the client

Enter any of the server's/bin folders:

sudo./zkcli.sh–server 127.0.0.1:2181  

6. End
