如何在CentOS上创建Kubernetes集群
好的,您的问题是如何使用ansible在node1、node2、node3上安装zookeeper,在所有master、node1、node2、node3上安装Hbase。
下面是一个示例ansible playbook代码,可以满足您的需求:
```
---
- name: Install Zookeeper and HBase
hosts: node1,node2,node3
become: yes
tasks:
- name: Install Java
yum:
name: java-1.8.0-openjdk
state: present
- name: Install Zookeeper
yum:
name: zookeeper
state: present
- name: Configure Zookeeper
lineinfile:
path: /etc/zookeeper/conf/zoo.cfg
line: "{{ item }}"
with_items:
- "server.1=master:2888:3888"
- "server.2=node1:2888:3888"
- "server.3=node2:2888:3888"
- "server.4=node3:2888:3888"
notify: Restart Zookeeper
- name: Start and enable Zookeeper
service:
name: zookeeper
state: started
enabled: yes
- name: Install HBase
yum:
name: hbase
state: present
- name: Configure HBase
lineinfile:
path: /etc/hbase/conf/hbase-site.xml
regexp: "<configuration>"
insertafter: "<configuration>"
line: |
<property>
<name>hbase.zookeeper.quorum</name>
<value>master,node1,node2,node3</value>
</property>
notify: Restart HBase
- name: Start and enable HBase
service:
name: hbase
state: started
enabled: yes
handlers:
- name: Restart Zookeeper
service:
name: zookeeper
state: restarted
- name: Restart HBase
service:
name: hbase
state: restarted
```
这个playbook会在node1、node2和node3上安装Zookeeper,并在Zookeeper配置文件中添加节点信息。同时,它会在所有master、node1、node2、node3上安装HBase,并在HBase配置文件中添加Zookeeper节点信息,然后启动这两个服务。您可以通过将这个代码保存为一个文件,例如install.yml,然后使用ansible-playbook命令来运行它,如下所示:
```
ansible-playbook install.yml
```
请注意,您需要确保在运行此playbook之前已经在服务器上设置了SSH密钥,并且可以通过SSH连接到这些服务器。此外,您需要在/etc/ansible/hosts文件中添加这些服务器的IP地址或主机名,以便Ansible知道要在哪些服务器上运行此playbook。
