2. Software version information

System: CentOS Linux release 7.5.1804 (Core) kafka:kafka_2.11-2.2.0Zookeeper version: 3.4.8ansible:ansible 2.7.10

Second, configuration preparation

1. Write playbook-related configuration files and first tree to take a look at the whole directory structure

Tree. ├── kafka │ ├── group_vars │ │ └── kafka │ ├── hosts │ ├── kafkainstall.yml │ └── templates │ ├── server.properties-1.j2 │ ├── server.properties-2.j2 │ ├── server.properties-3.j2 │ server.properties.j2 zookeeper group_vars │ └── zook ├── hosts ├── templates │ └── zoo.cfg.j2 └── zooKeeperinstall.yml

2. Set up relevant catalogs

Mkdir / chj/ansibleplaybook/kafka/group_vars-pmkdir / chj/ansibleplaybook/kafka/templatesmkdir / chj/ansibleplaybook/zookeeper/group_vars-pmkdir / chj/ansibleplaybook/zookeeper/templates

3. Write the configuration file for deploying zookeeper

PS: install the binary packages of jdk, kafka, and zk that you need, and replace them with the download address that you can access.

III. Deployment

1. Deploy the zookeeper cluster first

Cd / chj/ansibleplaybook/zookeeper/ansible-playbook-I hosts zooKeeperinstall.yml-b

2. Deploy kafka cluster

Cd / chj/ansibleplaybook/kafka/ansible-playbook-I hosts kafkainstall.yml-b
