graphite在centos7上的部署搭建

Graphite安裝筆記

實驗環境： CentOS7.5 x64

部署python的程序推薦使用virtualenv這列的虛擬環境來進行，防止污染系統自帶的python包。

 

安裝一些必要的rpm包

yum install cairo  -- 另外的2個包 cairo-devel pycairo 能夠不用安裝

安裝virtualenv

yum install python-pip

pip install virtualenv

激活虛擬環境

virtualenv /opt/graphite

source /opt/graphite/bin/activate

安裝graphite全套組件

export PYTHONPATH="/opt/graphite/lib/:/opt/graphite/webapp/"

pip install --no-binary=:all: https://github.com/graphite-project/whisper/tarball/master

pip install --no-binary=:all: https://github.com/graphite-project/carbon/tarball/master

 

pip install --no-binary=:all: https://github.com/graphite-project/graphite-web/tarball/master

若是這步提示某個依賴包版本不對，咱們能夠先人工執行下pip安裝依賴包。下面提供了一個正常運行的graphite上看到的pip包清單：

attrs==19.1.0

Automat==0.7.0

cachetools==3.1.1

cairocffi==0.9.0

cffi==1.12.3

constantly==15.1.0

Django==1.11.24

django-tagging==0.4.3

gunicorn==19.9.0

hyperlink==19.0.0

idna==2.8

incremental==17.5.0

pycparser==2.19

PyHamcrest==1.9.0

pyparsing==2.4.2

pytz==2019.2

scandir==1.10.0

six==1.12.0

Twisted==19.7.0

txAMQP==0.8.2

urllib3==1.25.3

whisper==1.2.0

zope.interface==4.6.0

初始化

cd /opt/graphite/webapp/graphite

cp local_settings.py.example local_settings.py

 

vim local_settings.py 修改以下3行代碼：

CONF_DIR = '/opt/graphite/conf'

STORAGE_DIR = '/opt/graphite/storage'

STATIC_ROOT = '/opt/graphite/webapp/content'

LOG_DIR = '/opt/graphite/storage/log/webapp'

 

初始化下數據，否則後面啓動graphite後會提示no such user 這類報錯

cd  /opt/graphite/webapp

PYTHONPATH=/opt/graphite/webapp django-admin.py migrate --settings=graphite.settings --run-syncdb   ## 若是上面第一步時候沒有yum install cairo的話，這步會報錯

 

拷貝graphite的配置文件

cd /opt/graphite/conf/

 

cp carbon.conf.example carbon.conf

cp storage-schemas.conf.example storage-schemas.conf   通常會改動這個文件裏面的配置，達到自定義key存儲週期

cp relay-rules.conf.example relay-rules.conf

cp dashboard.conf.example dashboard.conf

cp graphTemplates.conf.example graphTemplates.conf

cp blacklist.conf.example  blacklist.conf

cp aggregation-rules.conf.example aggregation-rules.conf

cp storage-aggregation.conf.example storage-aggregation.conf

啓動graphite套件

/opt/graphite/bin/carbon-relay.py start

/opt/graphite/bin/carbon-cache.py start

 

ss -lntp | egrep carbon

LISTEN     0      50           *:7002                     *:*                   users:(("carbon-cache.py",pid=48433,fd=11))

LISTEN     0      50           *:2013                     *:*                   users:(("carbon-relay.py",pid=37683,fd=13))

LISTEN     0      50           *:2014                     *:*                   users:(("carbon-relay.py",pid=37683,fd=15))

LISTEN     0      50           *:2003                     *:*                   users:(("carbon-cache.py",pid=48433,fd=13))

LISTEN     0      50           *:2004                     *:*                   users:(("carbon-cache.py",pid=48433,fd=14))

 

/opt/graphite/bin/run-graphite-devel-server.py --port=8085 --libs=/opt/graphite/webapp /opt/graphite  前臺啓動

啓動打點測試進程

python /opt/graphite/examples/example-client.py

安裝nginx

yum install nginx

cd /etc/nginx/conf.d

cat graphite.conf  內容以下：

upstream graphite {

    server 127.0.0.1:8085 fail_timeout=0;

}

 

server {

    listen 80 default_server;

 

    server_name _;

 

    root /opt/graphite/webapp;

 

    access_log /var/log/nginx/graphite.access.log;

    error_log  /var/log/nginx/graphite.error.log;

 

    location = /favicon.ico {

        return 204;

    }

 

    # serve static content from the "content" directory

    location /static {

        alias /opt/graphite/webapp/content;

        expires max;

    }

 

    location / {

        try_files $uri @graphite;

    }

 

    location @graphite {

        proxy_pass_header Server;

        proxy_set_header Host $http_host;

        proxy_redirect off;

        proxy_set_header X-Real-IP $remote_addr;

        proxy_set_header X-Scheme $scheme;

        proxy_connect_timeout 10;

        proxy_read_timeout 10;

        proxy_pass http://graphite;

    }

}

 

建立nginx相關文件

touch /var/log/nginx/graphite.access.log

touch /var/log/nginx/graphite.error.log

chmod 640 /var/log/nginx/graphite.*

chown nginx.nginx /var/log/nginx/graphite.*

 

啓動nginx

nginx -t

systemctl start nginx

訪問 192.168.2.4/ 以下圖

能夠看到已經有數據採集到了。

 

 

咱們能夠到grafana裏面配下graphite的數據源，而後展現數據，相似以下：

啓動brubeck（前臺）  【一款相似statsd的工具，只是不須要nodejs環境】

yum install jansson jansson-devel

yum install libmicrohttpd libmicrohttpd-devel

 

git clone https://github.com/github/brubeck.git

 

cd brubeck/

./script/bootstrap

 

 

mkdir /usr/local/brubeck/

 

cp brubeck /usr/local/brubeck/

vim /usr/local/brubeck/brubeck.json  增長配置文件以下：

 

{

  "sharding" : false,

  "server_name" : "prod-devops-graphite-01",

  "dumpfile" : "/var/lib/brubeck.dump",

  "capacity" : 15,

  "expire" : 20,

  "http" : ":8000",

 

  "backends" : [

    {

      "type" : "carbon",

      "address" : "localhost",

      "port" : 2003,

      "frequency" : 10

    }

  ],

 

  "samplers" : [

    {

      "type" : "statsd",

      "address" : "0.0.0.0",

      "port" : 8135,

      "workers" : 8,

      "multisock" : true,

      "multimsg" : 8

    }

  ]

}

 

【brubeck監聽在8135端口上，用於接收業務方的打點。2003 端口指的是carbon-cache的端口】

 

./brubeck --config brubeck.json   前臺啓動進程

測試打點到brubeck

echo "db.dba.dble2.front_conn:11111|g" | nc -u -w1 127.0.0.1 8135

修改graphite存儲數據的週期

cd /opt/graphite/conf

vim storage-schemas.conf

# Schema definitions for Whisper files. Entries are scanned in order,

# and first match wins. This file is scanned for changes every 60 seconds.

#

#  [name]

#  pattern = regex

#  retentions = timePerPoint:timeToStore, timePerPoint:timeToStore, ...

 

# Carbon's internal metrics. This entry should match what is specified in

# CARBON_METRIC_PREFIX and CARBON_METRIC_INTERVAL settings

[carbon]

pattern = ^carbon\.

retentions = 60:90d

 

[service-sla]

pattern = ^service.sla-pct.*

retentions = 10s:2d,1min:8d,10min:365d

 

[service1-rule]

pattern = ^service1\.timers\.Rule.*

retentions = 10s:5min,1min:1h,10min:7d

 

[service1-ic]

pattern = ^service1\.counters\.IC.*

retentions = 10s:24h,1min:7d

 

[logstash]

pattern = service1\.counters\.logstash.*

retentions = 10s:24h,1min:7d

 

[service1-timers]

pattern = ^service1\.timers\.*

retentions = 10s:5min,1min:1h,10min:1d,1h:365d

 

[service]

pattern = ^service1.*

retentions = 10s:24h,1min:6d,10min:365d

[counter]

pattern = ^.*\.counters\..*

retentions = 10s:24h,1min:7d,10min:30d

 

[timers]

pattern = ^.*\.timers\..*

retentions = 10s:5min,1min:1h,10min:1d,1h:30d

 

[db]

pattern = ^db\.*

retentions = 1min:30d

 

[default_10s_for_1hour]

pattern = .*

retentions = 10s:1h

 

vim storage-aggregation.conf  內容以下：

[min]

pattern = \.min$

xFilesFactor = 0.01

aggregationMethod = min

 

[max]

pattern = \.max$

xFilesFactor = 0.01

aggregationMethod = max

 

[all_sum]

pattern = \.sum$

xFilesFactor = 0.01

aggregationMethod = sum

 

[all_count]

pattern = \.count$

xFilesFactor = 0.01

aggregationMethod = sum

 

[service1_gauges]

pattern = ^service1.gauges

xFilesFactor = 0.01

aggregationMethod = last

 

[service1_counters]

pattern = ^service1\.counters

xFilesFactor = 0.01

aggregationMethod = sum

 

[service1]

pattern = ^service1.*

xFilesFactor = 0.01

 

[default_average]

pattern = .*

xFilesFactor = 0.01

aggregationMethod = average

 

注意，  修改成上面的2個文件後， 咱們須要重啓 carbon-cache進程才能生效。

建議：

一、graphite-web進程，建議經過supervisor來控制啓停。

二、我的認爲brubeck比statsd更好使，例若有些機器上可能不便於部署nodejs環境
