ansible实现ELK

一.环境准备

内存调2G！配置时间同步 ！！！

二.操作步骤

# 0.发送密钥
[root@m01 ~]# ssh-keygen
[root@m01 ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub root@172.16.1.54
[root@m01 ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub root@172.16.1.55
[root@m01 ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub root@172.16.1.56
[root@m01 ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub root@172.16.1.7
​
# 1.准备elasticsearch的roles目录
[root@m01 ~]# mkdir ansible_elasticsearch
[root@m01 ~]# cd ansible_elasticsearch/
[root@m01 ansible_elasticsearch]# ansible-galaxy init elasticsearch
​
# 2.准备hosts文件
[root@m01 ansible_elasticsearch]# cat hosts 
[db_group]
db04 ansible_ssh_host=172.16.1.54
db05 ansible_ssh_host=172.16.1.55
db06 ansible_ssh_host=172.16.1.56
[web_group]
web01 ansible_ssh_host=172.16.1.7
​
# 3.准备site.yml文件
[root@m01 ansible_elasticsearch]# cat site.yml 
- hosts: all
  roles:
    - { role: elasticsearch , when: (ansible_fqdn is match 'db*') or (ansible_fqdn is match 'web*')}
    
# 4.用jinjia模板准备elasticsearch的配置文件
[root@m01 elasticsearch]# cat templates/elasticsearch.yml.j2 
cluster.name: es-cluster
path.data: /service/es/data
path.logs: /service/es/logs
bootstrap.memory_lock: true
{% if ansible_fqdn == 'db04' %}
node.name: node-1
network.host: 10.0.0.54,127.0.0.1
{% elif ansible_fqdn == 'db05' %}
node.name: node-2
network.host: 10.0.0.55,127.0.0.1
{% else %}
node.name: node-3
network.host: 10.0.0.56,127.0.0.1
{% endif %}
http.port: 9200
discovery.zen.ping.unicast.hosts: ["10.0.0.54", "10.0.0.55","10.0.0.56"]
discovery.zen.minimum_master_nodes: 2
​

# 5.准备文件
[root@m01 files]# ll
