最近因公司專案增多，且環境也越來複雜，開發人員找我檢視錯誤日誌越來越頻繁，心裡便念想到ELK，心之所想，念之所達，快來get一項新技能吧
1、系統架構組成
- laravel日誌：日誌源通過filebeat將日誌寫進redis中介軟體
- logstsh：logstash通過input將redis資料拿來分析，通過其filter模組分析所需要的語句，然後輸出到elasticsearch 3.elasticsearch 接收logstash傳送過來的資料，並提供了一個分散式多使用者能力的全文搜尋引擎
- Kibana是一個優秀的前端日誌展示框架，它可以非常詳細的將日誌轉化為各種圖表，為使用者提供強大的資料視覺化支援。
二、各個服務的ip地址
laravel: 172.18.109.227
redis: 172.18.215.207
elasticsearch: 172.18.215.207
kibana: 172.18.215.207
複製程式碼三、laravel日誌伺服器配置：
- 配置filebeat yum原始檔

複製程式碼注意：我們只想把ERROR的資訊提取出來，所以logstash的配置檔案中把level 為ERROR的篩選了出來
六、配置elasticsearch伺服器
- 配置elasticsearch yum源
[elasticsearch-5.x]
name=Elasticsearch repository for 5.x packages
baseurl=https://artifacts.elastic.co/packages/5.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=1
autorefresh=1
type=rpm-md
複製程式碼- 安裝elasticsearch
yum install -y elasticsearch
複製程式碼- 配置elasticsearch
chown -R elasticsearch:elasticsearch /data/es-data
chown -R elasticsearch:elasticsearch /var/log/elstic
vim /etc/elasticsearch/elasticsearch.yml
#
# Use a descriptive name for the node:
#
node.name: Elstic
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
# 資料路徑
path.data: /data/es-data
#
# Path to log files:
#日誌路徑
path.logs: /var/log/elstic
...
# 監聽地址，設定為127，只保持本機訪問
network.host: 127.0.0.1
#
# Set a custom port for HTTP:
#
# 監聽的埠
http.port: 9200
#
# For more information, consult the network module documentation.
#
# --------------------------------- Discovery ----------------------------------
#
複製程式碼七、配置kibana服務
vim /etc/kibana/kibana.ym
# Kibana is served by a back end server. This setting specifies the port to use.
# 監聽的埠
server.port: 5601
# Specifies the address to which the Kibana server will bind. IP addresses and host names are both valid values.
# The default is 'localhost', which usually means remote machines will not be able to connect.
# To allow connections from remote users, set this parameter to a non-loopback address.
# 監聽地址，使用內網地址，然後用nginx反代
server.host: "127.0.0.1"
# Enables you to specify a path to mount Kibana at if you are running behind a proxy. This only affects
# the URLs generated by Kibana, your proxy is expected to remove the basePath value before forwarding requests
# to Kibana. This setting cannot end in a slash.
#server.basePath: ""
# The maximum payload size in bytes for incoming server requests.
#server.maxPayloadBytes: 1048576
# The Kibana server's name. This is used for display purposes.
#server.name: "your-hostname"
# The URL of the Elasticsearch instance to use for all your queries.
elasticsearch.url: "http://localhost:9200"
# When this setting's value is true Kibana uses the hostname specified in the server.host
# setting. When the value of this setting is false, Kibana uses the hostname of the host
# that connects to this Kibana instance.
#elasticsearch.preserveHost: true
# Kibana uses an index in Elasticsearch to store saved searches, visualizations and
# dashboards. Kibana creates a new index if the index doesn't already exist.
#kibana.index: ".kibana"
# The default application to load.
....
複製程式碼八、使用nginx反代kibana
$ cat /etc/nginx/conf.d/elk.conf
server {
listen 443 http2 ssl;

複製程式碼九、訪問kibana配置索引
啟動所以服務後再次訪問kibana，檢視效果。
總結：
- 此次因為伺服器數量有限,(不敢在正式伺服器上亂搞= =)只使用了兩臺伺服器，php的laravel日誌和filebeat服務一臺，作為寫入源，Redis，Elasticsearch、Logstash、Kibana，一臺作為日誌處理伺服器，(如果做多臺的話，監聽地址需要改變)。跑一段時間確認沒問題再上正式。
- 監聽的地址最好都使用內網地址，防止被攻擊。
