ELK實時分析之php的laravel項目日誌

最近因公司項目增多，且環境也越來複雜，開發人員找我查看錯誤日誌愈來愈頻繁，內心便念想到ELK，心之所想，念之所達，快來get一項新技能吧

一、系統架構組成

1. laravel日誌：日誌源經過filebeat將日誌寫進redis中間件
2. logstsh：logstash經過input將redis數據拿來分析，經過其filter模塊分析所須要的語句，而後輸出到elasticsearch 3.elasticsearch 接收logstash發送過來的數據，並提供了一個分佈式多用戶能力的全文搜索引擎
3. Kibana是一個優秀的前端日誌展現框架，它能夠很是詳細的將日誌轉化爲各類圖表，爲用戶提供強大的數據可視化支持。

2、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

3、laravel日誌服務器配置：

1. 配置filebeat yum源文件

[elastic-5.x]
name=Elastic 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
複製代碼

2. 安裝filebeat

yum install filebeat
複製代碼

3. 配置filebeat配置文件

...
#寫入源
- input_type: log
  paths:
  - /var/www/html/*/storage/logs/laravel-2018-12-29.log
...
#輸出至redis
output.redis:
  # Array of hosts to connect to.
  hosts: ["172.18.215.207:6379"]
  password: "***********"
  db: 0
  timeout: 5
  key: "php-01"

  # Optional protocol and basic auth credentials.
  #protocol: "https"
  #username: "elastic"
  #password: "changeme"

4、redis服務器

1. 安裝redis

yum install redis
複製代碼

2. 配置redis

...
# bind 192.168.1.100 10.0.0.1
bind 172.18.215.207
# bind 127.0.0.1 ::1
#
...
# are explicitly listed using the "bind" directive.
protected-mode yes

# Accept connections on the specified port, default is 6379 (IANA #815344).
# If port 0 is specified Redis will not listen on a TCP socket.
port 6379

# TCP listen() backlog.
#
# In high requests-per-second environments you need an high backlog in order
# to avoid slow clients connections issues. Note that the Linux kernel
# will silently truncate it to the value of /proc/sys/net/core/somaxconn so
# make sure to raise both the value of somaxconn and tcp_max_syn_backlog
# in order to get the desired effect.
tcp-backlog 511
...
# use a very strong password otherwise it will be very easy to break.
#

# Command renaming.
#
# It is possible to change the name of dangerous commands in a shared
# environment. For instance the CONFIG command may be renamed into something
# hard to guess so that it

5、配置logstash服務器

1. 配置logstash 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

2. logstash配置文件

#
# Where to fetch the pipeline configuration for the main pipeline
#
path.config: /etc/logstash/conf.d
#
# Pipeline configuration string for the main pipeline
#
# config.string:
#
...
path.config: /etc/logstash/conf.d
#
...
http.host: "127.0.0.1"
#
# Bind port for the metrics REST endpoint, this option also accept a range
# (9600-9700) and logstash will pick up the first available ports.
#
# http.port: 9600-9700
#
# ------------ Debugging Settings --------------
#
# Options for log.level:
# * fatal
# * error
# * warn
# * info (default)
# * debug
# * trace
#
# log.level: info
path.logs: /var/log/logstash
#
...


vim /etc/logstash/conf.d/nginx.conf

# 從redis將數據取出
input {
  redis {
    type => "php-01"
    host => "172.18.215.207"
    port => "6379"
    db => "0"
    password => "*************"
    data_type => "list"
    key => "php-01"
  }
}


# 格式化laravel日誌
filter {
   grok {
        match => [ "message","\[%{TIMESTAMP_ISO8601:logtime}\] %{WORD:env}\.(?<level>[A-Z]{4,5})\: %{GREEDYDATA:msg}}" ]
        }
}

output {
        #過濾level爲ERROR的日誌
        if [level] == "ERROR" {
         elasticsearch {
              hosts => ["127.0.0.1:9200"]
              index => "laravellog"
              user => "elastic"
              password => "changeme"
            }
        }

}
複製代碼

laravel的實例日誌爲

[2019-01-02 09:58:00] produce.INFO: {"code":200,"message":"成功","data":{"code":"1000","message":"成功"}}
[2019-01-02 10:00:03] produce.INFO: 不能充值的緣由帳戶金額不夠
[2019-01-02 10:00:03] produce.INFO: 不能充值的緣由帳戶金額不夠
[2019-01-02 10:00:03] produce.INFO: 不能充值的緣由帳戶金額不夠

注意：咱們只想把ERROR的信息提取出來，因此logstash的配置文件中把level 爲ERROR的篩選了出來

6、配置elasticsearch服務器

1. 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
複製代碼

2. 安裝elasticsearch

yum install -y elasticsearch
複製代碼

3. 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):
#
# 數據路徑
path.data: /data/es-data
#

# Path to log files:
#日誌路徑
path.logs: /var/log/elstic
...
# 監聽地址，設置爲127，只保持本機訪問
network.host: 127.0.0.1
#
# Set a custom port for HTTP:
#
# 監聽的端口
http.port: 9200
#
# For more information, consult the network module documentation.
#

7、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.
# 監聽的端口
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，而後用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.
....

8、使用nginx反代kibana

$ cat /etc/nginx/conf.d/elk.conf
server {
    listen 443 http2 ssl;
    listen [::]:443 http2 ssl;

    server_name *********;

	ssl on;
        ssl_certificate "**************";
        ssl_certificate_key "/usr/local/certificate/************";
        ssl_session_cache shared:SSL:1m;
        ssl_session_timeout  10m;
        ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
        ssl_prefer_server_ciphers on;
    #ssl_dhparam /etc/ssl/certs/dhparam.pem;

    ########################################################################
    # from https://cipherli.st/ #
    # and https://raymii.org/s/tutorials/Strong_SSL_Security_On_nginx.html #
    ########################################################################
    # Disable preloading HSTS for now. You can use the commented out header line that includes
    # the "preload" directive if you understand the implications.
    #add_header Strict-Transport-Security "max-age=63072000; includeSubdomains; preload";
    add_header Strict-Transport-Security "max-age=63072000; includeSubdomains";
    add_header X-Frame-Options DENY;
    add_header X-Content-Type-Options nosniff;

    ##################################

    # 這裏是反向代理到kibana服務 走http協議
    location / {
       proxy_pass   http://127.0.0.1:5601;
    }
}


#配置80端口重寫443端口
server {
        listen 80;
        server_name *********;
        rewrite ^/(.*)$ https://*********/$1;
}

9、訪問kibana配置索引

---

啓動因此服務後再次訪問kibana，查看效果。

大功告成~，之後可讓開發本身看錯誤日誌咯

---

總結：

• 這次由於服務器數量有限,(不敢在正式服務器上亂搞= =)只使用了兩臺服務器，php的laravel日誌和filebeat服務一臺，做爲寫入源，Redis，Elasticsearch、Logstash、Kibana，一臺做爲日誌處理服務器，(若是作多臺的話，監聽地址須要改變)。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。
