Logstash是一个开源的日志管理工具。项目地址:http://logstash.net/Logstash安装使用以下组件: Logstash Elasticsearch Redis Nginx Kibana 服务端: fqdn: dev.kanbier.lan (should be resolvable!) ip: 10.37.129.8 安装所需的软件 作者更喜欢使用RPM包

Logstash是一个开源的日志管理工具。 项目地址:http://logstash.net/ Logstash安装使用以下组件:
  • Logstash
  • Elasticsearch
  • Redis
  • Nginx
  • Kibana
服务端:
  • fqdn: dev.kanbier.lan (should be resolvable!)
  • ip: 10.37.129.8

安装所需的软件

作者更喜欢使用RPM包来安装软件,要注意版本号,不要去追求时髦用最新的最伟大的,Elasticsearch的版本应该匹配Logstash的版本。
$ vi /etc/yum.repos.d/logstash.repo
[logstash-1.4]
name=logstash repository for 1.4.x packages
baseurl=http://packages.elasticsearch.org/logstash/1.4/centos
gpgcheck=1
gpgkey=http://packages.elasticsearch.org/GPG-KEY-elasticsearch
enabled=1
$ vi /etc/yum.repos.d/elasticsearch.repo
[elasticsearch-1.0]
name=Elasticsearch repository for 1.0.x packages
baseurl=http://packages.elasticsearch.org/elasticsearch/1.0/centos
gpgcheck=1
gpgkey=http://packages.elasticsearch.org/GPG-KEY-elasticsearch
enabled=1
$ vi /etc/yum.repos.d/nginx.repo
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=0
enabled=1
$ rpm -Uvh http://mirror.1000mbps.com/fedora-epel/6/i386/epel-release-6-8.noarch.rpm
$ yum -y install elasticsearch redis nginx logstash

启用Kibana

$ wget https://download.elasticsearch.org/kibana/kibana/kibana-3.0.0.tar.gz
$ tar -xvzf kibana-3.0.0.tar.gz
$ mv kibana-3.0.0 /usr/share/kibana3
我们需要告诉Kibana在哪里可以找到elasticsearch。打开配置文件并修改elasticsearch参数:
$ vi /usr/share/kibana3/config.js
搜索“elasticsearch”参数,并对其进行修改以适应您的环境:
elasticsearch: "http://dev.kanbier.lan:9200",
您还可以修改default_route参数,默认打开logstash仪表板而不是Kibana欢迎页面:
default_route     : '/dashboard/file/logstash.json',
通过web界面访问:
$ wget https://raw.github.com/elasticsearch/kibana/master/sample/nginx.conf
$ mv nginx.conf /etc/nginx/conf.d/
$ vi /etc/nginx/conf.d/nginx.conf
server_name           dev.kanbier.lan;

配置redis

$ vi /etc/redis.conf
bind 10.37.129.8

配置Logstash?

可以使用Logstash文档上的logstash-complex.conf文件,并不是很负责,包含:
  • 从 /var/log目录读取文件
  • 打开5544端口以启用直接接收远程系统日志消息
  • 告诉logstash,利用本身的elasticsearch而不是嵌入的
$ vi /etc/logstash/conf.d/logstash-complex.conf
input {
  file {
    type => "syslog"
    # Wildcards work, here  
    path => [ "/var/log/*.log", "/var/log/messages", "/var/log/syslog" ]
    sincedb_path => "/opt/logstash/sincedb-access"
  }
  redis {
    host => "10.37.129.8"
    type => "redis-input"
    data_type => "list"
    key => "logstash"
  }
  syslog {
    type => "syslog"
    port => "5544"
  }
}
filter {
  grok {
    type => "syslog"
    match => [ "message", "%{SYSLOGBASE2}" ]
    add_tag => [ "syslog", "grokked" ]
  }
}
output {
 elasticsearch { host => "dev.kanbier.lan" }
}

启动服务

$ service redis start; chkconfig redis on
$ service elasticsearch start; chkconfig --add elasticsearch; chkconfig elasticsearch on
$ service logstash start; chkconfig logstash on
$ service nginx start; chkconfig nginx on
对于rsyslog现在你可以将这些行添加到/ etc/ rsyslog.conf
# ### begin forwarding rule ###
# The statement between the begin ... end define a SINGLE forwarding
# rule. They belong together, do NOT split them. If you create multiple
# forwarding rules, duplicate the whole block!
# Remote Logging (we use TCP for reliable delivery)
#
# An on-disk queue is created for this action. If the remote host is
# down, messages are spooled to disk and sent when it is up again.
$WorkDirectory /var/lib/rsyslog # where to place spool files
$ActionQueueFileName fwdRule1 # unique name prefix for spool files
$ActionQueueMaxDiskSpace 1g # 1gb space limit (use as much as possible)
$ActionQueueSaveOnShutdown on # save messages to disk on shutdown
$ActionQueueType LinkedList # run asynchronously
$ActionResumeRetryCount -1 # infinite retries if host is down
# remote host is: name/ip:port, e.g. 192.168.0.1:514, port optional
*.* @@10.37.129.8:5544
# ### end of the forwarding rule ###

如果有防火墙需要放开这些端口:

  • port 80 (for the web interface)
  • port 5544 (to receive remote syslog messages)
  • port 6379 (for the redis broker)
  • port 9200 (so the web interface can access elasticsearch)
