Graylog2日志服务安装配置

 软件版本:

  • mongodb-org-3.2.10
  • jdk-1.8.0 (推荐rpm包,不然要修改Graylog启动脚本定义的JAVA命令路径)
  • elasticsearch-2.4.1 (Graylog 2.x does not work with Elasticsearch 5.x)
  • graylog-server-2.1.1 (1.3版本之后已经集成graylog-web)

1.MongoDB

编辑/etc/yum.repos.d/mongodb-org-3.2.repo文件

[mongodb-org-3.2]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.2/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-3.2.asc

安装mongodb

yum install mongodb-org

启动mongodb

/etc/init.d/mongod start

2.Elasticsearch

编辑/etc/yum.repos.d/elasticsearch.repo文件

[elasticsearch-2.x]
name=Elasticsearch repository for 2.x packages
baseurl=https://packages.elastic.co/elasticsearch/2.x/centos
gpgcheck=1
gpgkey=https://packages.elastic.co/GPG-KEY-elasticsearch
enabled=1

安装elasticsearch

yum install elasticsearch

修改/etc/elasticsearch/elasticsearch.yml文件

cluster.name: graylog

启动elasticsearch

 /etc/init.d/elasticsearch start

 3.Graylog

安装graylog仓库

rpm -Uvh https://packages.graylog2.org/repo/packages/graylog-2.1-repository_latest.rpm
yum install graylog-server

安装epel仓库和pwgen软件

rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm
yum install -y pwgen (后面生成密码使用)

生成password_secret密码

pwgen -N 1 -s 96

生成root_password_sha2密码

echo -n 123456 | sha256sum

修改/etc/graylog/server/server.conf配置文件,将上面生成的密码写入到对应的变量

password_secret =
root_password_sha2 =
root_timezone = Asia/Shanghai
rest_listen_uri =  http://0.0.0.0:9000/api/
web_listen_uri = http://0.0.0.0:9000/
allow_highlighting = true (运行查询结果高亮)
elasticsearch_shards = 1 (当前只安装了一个elasticsearch)
elasticsearch_index_prefix = graylog

启动graylog

/etc/init.d/graylog-server start

登录graylog

http://IP(graylog-server):9000 进入graylog登录页
管理员帐号/密码: admin/123456(前面生成的密码)

4.日志采集

4.1测试日志获取

    • 添加tcp协议
      进入 System > Inputs > Inputs in Cluster > Raw/Plaintext TCP | Launch new input

取名"tcp 5555" 完成创建:

在安装有nc命令的Linux机器上执行:

echo `date` | nc graylog-server 5555

登录web页面查看获取的信息:

4.2 系统日志采集,使用rsyslog服务推送

添加Inputs端口,例如1514

修改采集端的rsyslog配置文件/etc/rsyslog.conf,开启UDP端口。重启rsyslog服务

$ModLoad imudp
$UDPServerRun 514

修改被采集端的rsyslog配置文件/etc/rsyslog.conf。重启rsyslog服务

$template GRAYLOGRFC5424,"<%pri%>%protocol-version% %timestamp:::date-rfc3339% %HOSTNAME% %app-name% %procid% %msg%\n"
*.* @172.17.20.123:1514(Inputs定义的端口);GRAYLOGRFC5424

搜集到的系统日志信息:

4.3 nginx日志采集,使用rsyslog服务推送

在nginx服务器上,修改rsyslog配置文件/etc/rsyslog.conf,修改如下配置

$ModLoad imfile

添加配置文件/etc/rsyslog.d/nginx.conf(名称自定义)

$InputFileName /var/log/nginx/error.log
$InputFileTag graylog-nginx-errorlog:
$InputFileStateFile state-graylog-nginx-errorlog
$InputRunFileMonitor
$InputFileName /var/log/nginx/access.log
$InputFileTag graylog-nginx-accesslog:
$InputFileStateFile state-graylog-nginx-accesslog
$InputRunFileMonitor
$InputFilePollInterval 10                 #等待10秒钟发送一次
if $programname == 'graylog-nginx-errorlog' then @172.17.20.123:514
if $programname == 'graylog-nginx-errorlog' then ~
if $programname == 'graylog-nginx-accesslog' then @172.17.20.123:514
if $programname == 'graylog-nginx-accesslog' then ~
*.*     @172.17.20.123:514

重启rsyslog服务

/etc/init.d/rsyslog restart

搜集到的nginx日志信息:

5.和kibana集成

  • 安装kibana

rpm -ivh https://download.elastic.co/kibana/kibana/kibana-4.6.2-x86_64.rpm

  • 启动kibana

/etc/init.d/kibana start

  • 创建graylog index mapping 文件,graylog-custom-mapping.json

{
  "template""graylog_*",
  "mappings" {
    "message" {
      "properties" {
        "http_method" {
          "type" "string",
          "index" "not_analyzed"
        },
        "http_response_code" {
          "type" "long"
        },
        "ingest_time" {
          "type" "date",
          "format""strict_date_time"
        },
        "took_ms" {
          "type" "long"
        }
      }
    }
  }
}

  • 加载index mapping到Elasticsearch

$ curl -X PUT -d @'graylog-custom-mapping.json' 'http://localhost:9200/_template/graylog-custom-mapping?pretty'
{
  "acknowledged" : true
}

  • 打开kibana页面,创建graylog_*索引

http://172.17.20.123:5601

  • 点击“ Discover ”,查看数据

 

 

6.使用Nxlog+Graylog Collector Sidecar搜集日志

6.1安装Nxlog

wget  https://nxlog.co/system/files/products/files/348/nxlog-ce-2.9.1716-1_rhel6.x86_64.rpm
yum install -y nxlog-ce-2.9.1716-1_rhel6.x86_64.rpm

可参考:http://blog.csdn.net/iwannarun/article/details/52604646

修改 /etc/nxlog.conf配置文件

Group nxlog

LogFile /var/log/nxlog/nxlog.log
LogLevel INFO

########################################
# Modules                              #

<Route 2>
    Path        in2 => out1

启动nxlog服务

/etc/init.d/nxlog start

查看日志排错
/var/log/nxlog/nxlog.log 

 6.2安装Graylog Collector Sidecar

官方文档:http://docs.graylog.org/en/latest/pages/collector_sidecar.html#id3

service nxlog stop
chkconfig --del nxlog
gpasswd -a nxlog root
chown -R nxlog.nxlog /var/spool/collector-sidecar/nxlog

https://github.com/Graylog2/collector-sidecar/releases 下载地址
rpm -ivh collector-sidecar-0.1.4-1.x86_64.rpm
graylog-collector-sidecar -service install

修改/etc/graylog/collector-sidecar/collector_sidecar.yml 配置文件

server_url: http://127.0.0.1:9000/api/  #改为graylog server机器的IP
update_interval: 10
tls_skip_verify: false
send_status: true
list_log_files:
node_id: graylog-collector-sidecar
collector_id: file:/etc/graylog/collector-sidecar/collector-id
cache_path: /var/cache/graylog/collector-sidecar
log_path: /var/log/graylog/collector-sidecar
log_rotation_time: 86400
log_max_age: 604800
tags:
    - messages
backends:
    - name: nxlog
      enabled: true
      binary_path: /usr/bin/nxlog
      configuration_path: /etc/graylog/collector-sidecar/generated/nxlog.conf

6.3在web页面配置

可参考:http://blog.csdn.net/iwannarun/article/details/52802680

7.使用filebeat+Graylog Collector Sidecar搜集日志

7.1安装Graylog Collector Sidecar

https://github.com/Graylog2/collector-sidecar/releases 下载地址
rpm -ivh collector-sidecar-0.1.4-1.x86_64.rpm
graylog-collector-sidecar -service install

7.2修改/etc/graylog/collector-sidecar/collector_sidecar.yml 配置文件

server_url: http://IP:9000/api/ #改为graylog server机器的IP
update_interval: 10
tls_skip_verify: false
send_status: true
list_log_files:
node_id: graylog-collector-sidecar
collector_id: file:/etc/graylog/collector-sidecar/collector-id
cache_path: /var/cache/graylog/collector-sidecar
log_path: /var/log/graylog/collector-sidecar
log_rotation_time: 86400
log_max_age: 604800
tags:
    - nginx log  #按需修改
backends:
    - name: nxlog
      enabled: false  #不开启ngxlog
      binary_path: /usr/bin/nxlog
      configuration_path: /etc/graylog/collector-sidecar/generated/nxlog.conf
    - name: filebeat
      enabled: true #开启filebeat
      binary_path: /usr/bin/filebeat
      configuration_path: /etc/graylog/collector-sidecar/generated/filebeat.yml

7.3在web页面上配置

可参考:https://www.linuxea.com/1599.html

a)配置收集器

 

b)配置收集器中的OUTPUT

 

c)配置收集器中的INPUT

如果有多个日志文件可以使用*号等正则匹配,或者['/var/log/openresty/int.error.log', '/var/log/openresty/ext.error.log']定义多个。

d)在收集日志的客户端启动 collector-sidecar

/etc/init.d/collector-sidecar start

/var/log/collector-sidecar.err 可查看日志排错

启动成功后会把刚在页面上的配置自动生成filebeat配置文件

启动后生成的配置文件
/etc/graylog/collector-sidecar/generated/filebeat.yml 

 

e)配置Graylog Server的INPUT接口

 

配置完保存后,garylog会在服务端启动定义的tcp端口5044

 在web页面验证是否收到日志

 

graylog有告警功能,可以匹配到需要触发的条件进行日志告警。
