Logstash+Elasticsearch+Kibana+S3+Nginx
build our private log query system

  • System structure
https://docs.google.com/a/edanzgroup.com/drawings/d/srkTNdoc8oWvEPe5ZkV6xgA/image?w=624&h=445&rev=311&ac=1

  • How to setup

    • Logstash-index (Logstash server)
      yum -y install java-1.7.0-openjdk
    • Install and configure Elasticsearch ( Logstash 1.4.2 recommends Elasticsearch 1.1.1 )
      rpm --import http://packages.elasticsearch.org/GPG-KEY-elasticsearch
      vi /etc/yum.repos.d/elasticsearch.repo  ( Add the following repository configuration )
      [elasticsearch-1.1]
      name=Elasticsearch repository for 1.1.x packages
      baseurl=http://packages.elasticsearch.org/elasticsearch/1.1/centos
      gpgcheck=1
      gpgkey=http://packages.elasticsearch.org/GPG-KEY-elasticsearch
      enabled=1
    • yum -y install elasticsearch-1.1.1
    • vi /etc/elasticsearch/elasticsearch.ymlAdd the following line somewhere in the file, to disable dynamic scripts      script.disable_dynamic: true
    • You will also want to restrict outside access to your Elasticsearch instance, so outsiders can't read your data or shutdown your Elasticseach cluster through the HTTP API. Find the line that specifies network.host and uncomment it so it looks like this:
      　　network.host: localhost
    • Then disable multicast by finding the discovery.zen.ping.multicast.enabled item and uncommenting so it looks like this:    discovery.zen.ping.multicast.enabled: false
    • chkconfig --add elasticsearch
    • service elasticsearch restart

  • Install Kibana (  Logstash 1.4.2 recommends Kibana 3.0.1 )

    • cd ~; curl -O https://download.elasticsearch.org/kibana/kibana/kibana-3.0.1.tar.gztar xvf kibana-3.0.1.tar.gzvi ~/kibana-3.0.1/config.js  ( replace the port number (9200 by default) with 80 )    elasticsearch: "http://"+window.location.hostname+":80"





    • mkdir -p /usr/share/nginx/kibana3
    • cp -R ~/kibana-3.0.1/* /usr/share/nginx/kibana3/

  • Install Nginx

    • rpm -Uvh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
    • yum -y install nginx
    • cd ~; curl -OL https://github.com/elasticsearch/kibana/raw/master/sample/nginx.conf
    • vi nginx.conf  ( Find and change the values of the server_name to your FQDN (or localhost if you aren't using a domain name) and root to where we installed Kibana, so they look like the following entries )

server_name FQDN;
root  /usr/share/nginx/kibana3;

  • cp ~/nginx.conf /etc/nginx/conf.d/default.conf
  • htpasswd -c /etc/nginx/conf.d/kibana.myhost.org.htpasswd linuxblind
  • Password: linuxblind
  • chkconfig --levels 235 nginx on
  • service nginx restart


  • Install and configure Logstash


  • vi /etc/yum.repos.d/logstash.repo (Add the following repository configuration)
[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

  • yum -y install logstash-1.4.2
  • vi /etc/logstash/conf.d/logstash.conf ( see below)
  • service logstash start




    • vi /etc/yum.repos.d/logstash.repo (Add the following repository configuration)
    • yum -y install java-1.7.0-openjdk
    • cd /etc/pki/tls; openssl req -new -newkey rsa:4096 -days 3650 -nodes -x509 -subj "/C=CN/ST=Beijing/L=Beijing/O=IT/CN=logstash.linuxblind.com"  -keyout logstash.linuxblind.com.key -out logstash.linuxblind.com.certLogstash agent
    • Generate SSL Certificate
    • Install JDK1.7
    • Install and configure Logstash

[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

  • yum -y install logstash-1.4.2
  • service logstash start
=============== Logstash Collect maillog (sendmail) =====================
Step1:

  • Copy SSL certificate from logstash-indexer to logstash-agent

    • scp /etc/pki/tls/certs/logstash.linuxblind.com.cert user@logstash_agent_IP:/tmp

Step2:

  • In logstash-agent


  • Install and Configure logstash-forwarder

    • Change content like below:
    • cd ~; curl -O http://packages.elasticsearch.org/logstashforwarder/centos/logstash-forwarder-0.3.1-1.x86_64.rpm
    • rpm -ivh ~/logstash-forwarder-0.3.1-1.x86_64.rpm
    • cd /etc/init.d/; curl -o logstash-forwarder http://logstashbook.com/code/4/logstash_forwarder_redhat_init
    • chmod +x logstash-forwarder
    • curl -o /etc/sysconfig/logstash-forwarder http://logstashbook.com/code/4/logstash_forwarder_redhat_sysconfig
    • vi /etc/sysconfig/logstash-forwarder

LOGSTASH_FORWARDER_OPTIONS="-config /etc/logstash-forwarder -spool-size 100"

  • cp /tmp/logstash.linuxblind.com.cert /etc/pki/tls/certs/
  • vi /etc/logstash-forwarder
{
"network": {
     "servers": [ "logstash.linuxblind.com:5000" ],
    "timeout": 15,
    "ssl certificate": "/etc/pki/tls/certs/logstash.linuxblind.com.cert",
    "ssl key": "/etc/pki/tls/private/logstash.linuxblind.com.key",
    "ssl ca": "/etc/pki/tls/certs/logstash.linuxblind.com.cert"
  },
  "files": [
    {
      "paths": [
        "/var/log/message"
       ],
      "fields": { "type": "syslog" }
    },
    {
      "paths": [
        "/var/log/maillog"
       ],
      "fields": { "type": "maillog" }
    }
   ]
}

  • chkconfig logstash-forwarder on
  • /etc/init.d/logstash-forwarder start
  • crtl+c  # exit
Step3:

  • In logstash-indexer

    • Modified /opt/logstash/patterns/grok-patterns and append following content

# Match for sendmail
#EMAIL [.a-zA-Z0-9_-]+@%{IPORHOST}
LOGIN [.a-zA-Z0-9_-]+
EMAIL %{LOGIN}@%{IPORHOST}
DSN [0-9][.][0-9][.][0-9]
QID [A-za-z0-9]{14}

# Match a>
SENDMAIL_TO_1 %{SYSLOGBASE} %{QID:qid}: to=, (%{WORD}=%{DATA},)+>
# Match a>

# Match a message with no>SENDMAIL_TO_4 %{SYSLOGBASE} %{QID:qid}: to=, (%{WORD}=%{DATA},)+ stat=%{GREEDYDATA:status}
### TODO - match multiple recipients in To: field.
SENDMAIL_TO_5 %{SYSLOGBASE} %{QID:qid}: to=(,)+ (%{WORD}=%{DATA},)+ %{GREEDYDATA:status}
SENDMAIL_TO (%{SENDMAIL_TO_1}|%{SENDMAIL_TO_2}|%{SENDMAIL_TO_3}|%{SENDMAIL_TO_4})

SENDMAIL_FROM %{SYSLOGBASE} %{QID:qid}: from=, (%{WORD}=%{DATA},)+>SENDMAIL_OTHER_1 %{SYSLOGBASE} %{QID:qid}: %{GREEDYDATA:message}

SENDMAIL_OTHER_4 %{SYSLOGBASE} ruleset=tls_server, arg1=SOFTWARE,>SENDMAIL_OTHER_5 %{SYSLOGBASE} STARTTLS=client, error: %{GREEDYDATA:message}

SENDMAIL_RELAY %{SYSLOGBASE} ruleset=check_relay, arg1=(\[)?%{IPORHOST}(\])?, arg2=%{IP:ip},>
SENDMAIL_AUTH_1 %{SYSLOGBASE} AUTH=server,>
SENDMAIL_AUTH_2 %{SYSLOGBASE} AUTH=server,>SENDMAIL_AUTH (%{SENDMAIL_AUTH_1}|%{SENDMAIL_AUTH_2})
SENDMAIL_OTHER (%{SENDMAIL_OTHER_1}|%{SENDMAIL_OTHER_2}|%{SENDMAIL_OTHER_3}|%{SENDMAIL_OTHER_4}|%{SENDMAIL_OTHER_5})
SENDMAIL (%{SENDMAIL_TO}|%{SENDMAIL_FROM}|%{SENDMAIL_OTHER}|%{SENDMAIL_AUTH}|%{SENDMAIL_RELAY})

  • Modified /etc/logstash/conf.d/10-syslog.conf and Add following content in right place.
if [type] == "maillog" {
                grok {
                         match => [ "message", "%{SENDMAIL_TO_1}",
                                    "message", "%{SENDMAIL_TO_2}",
                                    "message", "%{SENDMAIL_TO_3}",
                                    "message", "%{SENDMAIL_TO_4}",
                                    "message", "%{SENDMAIL_TO_5}",
                                    "message", "%{SENDMAIL_TO}",
                                    "message", "%{SENDMAIL_FROM}",
                                    "message", "%{SENDMAIL_OTHER_1}",
                                    "message", "%{SENDMAIL_OTHER_2}",
                                    "message", "%{SENDMAIL_OTHER_3}",
                                    "message", "%{SENDMAIL_OTHER_4}",
                                    "message", "%{SENDMAIL_OTHER_5}",
                                    "message", "%{SENDMAIL_RELAY}",
                                    "message", "%{SENDMAIL_AUTH_1}",
                                    "message", "%{SENDMAIL_AUTH_2}",
                                    "message", "%{SENDMAIL_AUTH}",
                                    "message", "%{SENDMAIL_OTHER}",
                                    "message", "%{SENDMAIL}"
                                    ]
