python+logstash+elasticsearch+Kibana日志方案

python用的是python-logstash库https://github.com/vklochan/python-logstash

这一套用起来都比较方便.

logstash安装,配置,运行

下载并安装logstash

打开https://www.elastic.co/downloads/logstash,找到最新版下载链接,使用wget下载rpm,然后通过yum安装

wget https://download.elastic.co/logstash/logstash/packages/centos/logstash-2.1.1-1.noarch.rpm
yum install logstash-2.1.1-1.noarch.rpm

也可以直接通过repo安装:https://www.elastic.co/guide/en/logstash/current/package-repositories.html

配置logstash

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

input {  
  tcp {
    port => 5959
    codec => json
  }  
}
output {
  elasticsearch { hosts => ["localhost:9200"] }
}

运行logstash

chkconfig logstash on
/etc/init.d/logstash start
telnet 127.0.0.1 5959 #test

Python logstash

安装python包

pip install python-logstash

测试脚本 vim test.py

import logging
import logstash
import sys

host = 'localhost'

test_logger = logging.getLogger('python-logstash-logger')
test_logger.setLevel(logging.DEBUG)
test_logger.addHandler(logstash.TCPLogstashHandler(host, 5959, version=1))

test_logger.error('python-logstash: test logstash error message.')
test_logger.info('python-logstash: test logstash info message.')
test_logger.warning('python-logstash: test logstash warning message.')

extra = {
    'test_string': 'python version: ' + repr(sys.version_info),
    'test_boolean': True,
    'test_dict': {'a': 1, 'b': 'c'},
    'test_float': 1.23,
    'test_integer': 123,
    'test_list': [1, 2, '3'],
}
test_logger.info('python-logstash: test extra fields', extra=extra)

检查是否成功

curl http://127.0.0.1:9200/_search?pretty&q=logstash

kibana安装使用

https://www.elastic.co/downloads/kibana找到最新版本的kibana

wget https://download.elastic.co/kibana/kibana/kibana-4.3.1-linux-x64.tar.gz
tar -zxf kibana-4.3.1-linux-x64.tar.gz

vim config/kibana.yml,找到elasticsearch.url这行,根据情况决定是否要修改,如果修改记得去掉前面的注释符号

运行bin/kibana启动服务,访问http://127.0.0.1:5601/,点击创建即可

配置nginx访问

安装htpasswd工具,生成账号密码

 yum install httpd-tools
 htpasswd -b -c /data/kibana.htpasswd username password

配置nginx server

upstream kibana {
    server 127.0.0.1:5601 fail_timeout=0;
}

server {
    listen      80;
    server_name          kibana.domain.com;

    location / {
        auth_basic "Restricted";
        auth_basic_user_file /data/kibana.htpasswd;
        proxy_pass http://kibana;
   }
}

重启nginx

nginx -s reload
