CentOS 7 installation and configuration of Zookeeper

CentOS 7 installation and configuration of Zookeeper

To learn about Dubbo, you need to use Zookeeper. Here we record the installation and configuration of Zookeeper in CentOS 7 Linux.

1. Download the zookeeper package: Official Address

2. Upload the package to linux and put it in the/usr/local directory. Of course, you can also store the package wherever it is, and decompress it to the/usr/local/zookeeper directory.

First, create the zookeeper folder.

Mkdir-p/usr/local/zookeeper

Decompress the zookeeper package to the zookeeper directory.

Tar-zxvf zookeeper-3.4.10.tar.gz-C zookeeper

3. first enter the/usr/local/zookeeper/zookeeper-3.4.10/conf directory

Cd/usr/local/zookeeper/zookeeper-3.4.10/conf

Assign a value to the zoo_sample.cfg file under the/usr/local/zookeeper/zookeeper-3.4.10/conf directory and rename it zoo. cfg,

Cp zoo_sample.cfg zoo. cfg

This zoo. cfg is the configuration file of zookeeper. Here I set up a standalone version. If you want to set up a cluster version, you can modify the configuration file.

Modify zoo. cfg

Enter the bin directory of zookeeper.

Cd/usr/local/zookeeper/zookeeper-3.4.10/bin

Start zookeeper

./ZkServer. sh start

The result is as follows:

Exploitation

./ZkServer. sh status

View the current zookeeper status

So far, the single-host version of zookeeper has been set up successfully.

4. Change zookeeper to startup

Go to the/etc/rc. d/init. d directory.

Cd/etc/rc. d/init. d

Create a file named zookeeper

Touch zookeeper

Edit the zookeeper File

Vi zookeeper

Press the I key to enter the insert mode and change the file

#! /Bin/bash
# Chkconfig: 2345 10 90
# Description: service zookeeper
Export JAVA_HOME =/usr/local/java/jdk1.8.0 _ 162
Export ZOO_LOG_DIR =/usr/local/zookeeper/zookeeper-3.4.10/logs
ZOOKEEPER_HOME =/usr/local/zookeeper/zookeeper-3.4.10
Su root $ {ZOOKEEPER_HOME}/bin/zkServer. sh "$1"

Then exit and save.

Add executable permissions to the new/etc/rc. d/init. d/zookeeper File

Chmod + x/etc/rc. d/init. d/zookeeper

Add the zookeeper script to the startup Item.

Chkconfig -- add zookeeper

Restart linux

Reboot

After restart

Service zookeeper status

Check whether zookeeper is started

The result is as follows:
