一、安装ansible
1） 配置自己的yum 源
[root@node-4 ~]# cat /etc/yum.repos.d/local.repo
[centos]
name=centos
baseurl=
http://192.168.100.20/openstack/centos
gpgcheck=0
enabeld=1
[ansible]
name=ansible
gpgcheck=0
enabled=1
baseurl=
http://192.168.100.20/openstack/ansible
2） 下载ansible 修改配置
[root@node-4 ~]# vi /etc/ansible/hosts
[node_1]
node1 node_name=node1
[node_2]
node2 node_name=node2
[node_3]
node3 node_name=node3
[root@node-4 ~]# ansible all -m ping
node2 | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/bin/python"
},
"changed": false,
"ping": "pong"
}
node3 | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/bin/python"
},
"changed": false,
"ping": "pong"
}
node1 | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/bin/python"
},
"changed": false,
"ping": "pong"
}
3） 创建部署的目录
[root@node-4 ~]# mkdir install_elk
[root@node-4 ~]# cd install_elk/
[root@node-4 install_elk]# mkdir -p roles/{elk,kibana,logstash}/{tasks,files,templates,vars}
二、编写role
1） 搭建elasticserch
[root@node-4 install_elk]# tree roles/
roles/
├── elk
│ ├── files
│ │ ├── elasticsearch-6.0.0.rpm
│ │ ├── hosts
│ │ ├── limits.conf
│ │ ├── local.repo
│ │ └── sysctl.conf
│ ├── tasks
│ │ └── main.yaml
│ ├── templates
│ │ └── elasticsearch.yml.j2
│ └── vars
├── kibana
│ ├── files
│ │ ├── kibana-6.0.0-x86_64.rpm
│ │ └── kibana.yml
│ ├── tasks
│ │ └── main.yaml
│ ├── templates
│ └── vars
└── logstash
├── files
│ ├── logstash-6.0.0.rpm
│ ├── logstash.service
│ ├── logstash.yml
│ └── test.conf
├── tasks
│ └── main.yaml
├── templates
└── vars
15 directories, 15 files
root@node-4 ~]# cd install_elk/roles/elk/files/
[root@node-4 files]# cp /etc/hosts .
[root@node-4 files]# cp /etc/yum.repos.d/local.repo .
[root@node-4 files]# cp /etc/security/limits.conf .
[root@node-4 files]# cp /etc/sysctl.conf .
[root@node-4 files]# cp /root/elasticsearch-6.0.0.rpm .
[root@node-4 files]# ls
elasticsearch-6.0.0.rpm hosts limits.conf local.repo sysctl.conf
#这里 我提前下载了 下 elastcisearch 的包
[root@node-4 files]# mv /etc/elasticsearch/elasticsearch.yml ../templates/elasticsearch.yml.j2
[root@node-4 roles]# cat elk/templates/elasticsearch.yml.j2
cluster.name: my-application
node.name: {{node_name}}
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
network.host: 0.0.0.0
http.port: 9200
discovery.zen.ping.unicast.hosts: ["node1","node2","node3"]
discovery.zen.minimum_master_nodes: 2
[root@node-4 elk]# vi tasks/main.yaml
[root@node-4 elk]# vi tasks/main.yaml
- name: stop selinux
shell: setenforce 0
- name: rm repo
shell: rm -rf /etc/yum.repos.d/*
- name: cp hosts

- name: shell sysctl
shell: sysctl -p
- name: yum java
shell: yum -y install java-1.8.0-openjdk java-1.8.0-openjdk-devel
- name: cp elk
copy: src=elasticsearch-6.0.0.rpm dest=/root/
- name: yum elk
yum: name=/root/elasticsearch-6.0.0.rpm
- name: copy elk.conf
template: src=elasticsearch.yml.j2 dest=/etc/elasticsearch/elasticsearch.yml
- name: start elk
shell: systemctl restart elasticsearch
[root@node-4 install_elk]# cat roles/elk/files/limits.conf
* soft nofile 65536 #这里仅显示最后部分 （在最后添加 这两个）
* hard nofile 65536
[root@node-4 files]# cat sysctl.conf
# sysctl settings are defined through files in
# /usr/lib/sysctl.d/, /run/sysctl.d/, and /etc/sysctl.d/.
#
# Vendors settings live in /usr/lib/sysctl.d/.
# To override a whole file, create a new file with the same in
# /etc/sysctl.d/ and put new settings there. To override
# only specific settings, add a file with a lexically later
# name in /etc/sysctl.d/ and put new settings there.
#
# For more information, see sysctl.conf(5) and sysctl.d(5).
vm.max_map_count = 262144
2） 编写logstash
[root@node-4 roles]# cat logstash/files/logstash.service
[Unit]
Description=logstash
[Service]
ExecStart=/usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/
ExecReload=/bin/kill -HUP $MAINPID
KillMode=process
#Restart=on-failure
[Install]
WantedBy=multi-user.target
[root@node-4 roles]# cat logstash/files/logstash.yml
pipeline:
batch:
size: 125
delay: 5
path.data: /var/lib/logstash
path.config: /etc/logstash/conf.d/*.conf
http.host: "0.0.0.0"
http.port: 9600-9700
log.level: info
path.logs: /var/log/logstash
[root@node-4 roles]# cat logstash/files/test.conf # 注意缩进
[root@node-4 roles]# cat logstash/files/test.conf
input{
file{
path => "/var/log/messages"
start_position => "beginning"
}
}
output{
elasticsearch{
hosts => ["177.16.1.113:9200"]
index => "amessage-%{+YYYY.MM.dd}"
}
}
[root@node-4 roles]# cat logstash/tasks/main.yaml
- name: cp logstash
copy: src=logstash-6.0.0.rpm dest=/root/
- name: yum logstash-6.0.0.rpm
yum: name=/root/logstash-6.0.0.rpm
- name: cp test.conf
copy: src=test.conf dest=/etc/logstash/conf.d/
- name: cp logstash.yml
copy: src=logstash.yml dest=/etc/logstash/
- name: cp service
copy: src=logstash.service dest=/etc/systemd/system/
- name: start logstash
shell: systemctl daemon-reload && systemctl restart logstash
3） 编写kibana
[root@node-4 roles]# cat kibana/files/kibana.yml
server.port: 5601
server.host: "0.0.0.0"
elasticsearch.url: "http://177.16.1.113:9200"
[root@node-4 roles]# cat kibana/tasks/main.yaml
- name: cp kibana-6.0.0-x86_64.rpm
copy: src=kibana-6.0.0-x86_64.rpm dest=/root
- name: yum kibana-6.0.0-x86_64.rpm
yum: name=kibana-6.0.0-x86_64.rpm
- name: cp kibana.yml
copy: src=kibana.yml dest=/etc/kibana/
- name: start kibana
shell: systemctl restart kibana
三、编写出口加运行结果
[root@node-4 install_elk]# vi install_elk.yaml
---
- hosts: all
remote_user: root
roles:
- elk
- hosts: node_1
remote_user: root
roles:
- kibana
- hosts: node_2
remote_user: root
roles:
- logstash
[root@node-4 install_elk]# ansible-playbook install_elk.yaml
