Centos7 install Zookeeper, start, eliminate Jar package conflict

1. Zookeeper download address:

http://mirror.bit.edu.cn/apache/zookeeper/

2. Upload the downloaded compressed package to Centos7, (note: download the compressed package of /bin, the reason is Baidu)

3. Unzip the compressed package under /usr/local (path custom)

tar -zxvf apache-zookeeper-3.6.1-bin.tar.gz -C /usr/local

4. Rename the name of the folder (no operation required)

[root@VM_0_17_centos ~]# cd /usr/local

[root@VM_0_17_centos ~]# mv apache-zookeeper-3.6.1-bin zookeeper-3.6.1

5. Enter the zookeeper's config directory and copy a configuration file

[root@VM_0_17_centos ~]# cp  zoo_sample.cfg  zoo.cfg

6. Then enter the bin directory of zookeeper and start the server

[root@VM_0_17_centos ~]# ./zkServer.sh start

7, finally start the client

[root@VM_0_17_centos bin]# ./zkCli.sh

Enter the command after success: ls /
success is shown as follows!

Note: When the version of zookeeper in your pom is higher than that of your server, you need to exclude the jar package
