beat配置文件
[root@varnish1 filebeat-5.5.0-linux-x86_64]# grep -v "#" filebeat.yml | sed '/^$/d' filebeat.prospectors: - input_type: log paths: - /data/*.log tags: ["haproxy-log"] output.kafka: enabled : true hosts: ["kafka1:9092","kafka2:9092","kafka3:9092"] topic: logostash-%{[type]} [root@varnish1 filebeat-5.5.0-li
logstash配置文件
[root@logstashserver etc]# cat logstash.conf input { kafka { bootstrap_servers => "kafka1:9092,kafka2:9092,kafka3:9092" topics => ["logostash-log"] consumer_threads => 5 decorate_events => true } } filter { grok{ patterns_dir => "/data/logstash/patterns" match => {"message" => "%{SYSLOGTIMESTAMP:syslog_timestamp} %{IPORHOST:syslog_server} %{SYSLOGPROG}: %{IP:client_ip}:%{INT:client_port} \[%{HAPROXYDATE:accept_date}\] %{NOTSPACE:frontend_name} %{NOTSPACE:backend_name}/%{NOTSPACE:server_name} %{INT:time_request}/%{INT:time_queue}/%{INT:time_backend_connect}/%{INT:time_backend_response}/%{NOTSPACE:time_duration} %{INT:http_status_code} %{NOTSPACE:bytes_read} %{FENG:captured_request_cookie} %{FENG:captured_response_cookie} %{NOTSPACE:termination_state} %{INT:actconn}/%{INT:feconn}/%{INT:beconn}/%{INT:srvconn}/%{NOTSPACE:retries} %{INT:srv_queue}/%{INT:backend_queue} \"%{WORD:verb} %{URIPATHPARAM:request} %{WORD:http_socke}/%{NUMBER:http_version}\""} } geoip { source => "client_ip" fields => ["ip","city_name","country_name","location"] add_tag => [ "geoip" ] } } output { elasticsearch { hosts => ["es1:9200","es2:9200","es3:9200"] manage_template => true index => "logstash-feng.log-%{+YYYY-MM-dd}" } }
在es1上操作：
下载elasticsearch5.5安装：
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.5.0.tar.gz
解压：
tar -zxvf elasticsearch-5.5.0.tar.gz
mv elasticsearch-5.5.0 elasticsearch
接下来创建el用户，因为elasticsearch不允许以root运行（其实也可以运行，需要配置）。
1.设置虚拟 –Xms -Xmx 内存大小
vim /data/elasticsearch/config/jvm.options
2.设置虚拟内存
echo “vm.max_map_count=262144” >> /etc/sysctl.conf
3.关闭swap分区
Swapoff –a
修改配置文件fstab
#/dev/mapper/centos-swap swap swap defaults 0 0
4.设置elastrisearch用户名密码
useradd es
passwd es
5. 需要修改
/etc/security/limits.conf
es soft memlock unlimited
es hard memlock unlimited
6.修改：
/etc/sysctl.conf
vm.swappiness=0
之后重启机器
chown -R es:es /data/elasticsearch
su - es
cd elasticsearch/conf/
修改配置文件：
vim elasticsearch.yml
cluster.name: senyint_elasticsearch node.name: es1 path.data: /data/elasticsearch/data path.logs: /data/elasticsearch/logs bootstrap.memory_lock: false network.host: 192.168.99.8 http.port: 9200 discovery.zen.ping.unicast.hosts: ["es1", "es2", "es3"] http.cors.enabled: true http.cors.allow-origin: "*"
xpack.security.enabled: false #安装x-pack 插件使用
安装X-Pack
在5.x版本中一些es插件(Shield, Watcher, Marvel, Graph, Reporting)都集成在x-pack组件中
在Es的根目录(每个节点),运行 bin/elasticsearch-plugin进行安装
bin/elasticsearch-plugin install x-pack
安装head插件：
#elasticsearch-head 不能放置在 /data/elasticsearch/plugins/目录下，否者报错
cd /data/elasticsearch/
git clone git://github.com/mobz/elasticsearch-head.git
root用户
cd /data/
wget https://nodejs.org/dist/v6.11.1/node-v6.11.1-linux-x64.tar.xz
xz -d node-v6.11.1-linux-x64.tar.xz
tar -xf node-v6.11.1-linux-x64.tar
vi /etc/profile
export NODE_HOME=/data/node-v6.11.1-linux-x64
export PATH=${PATH}:${NODE_HOME}/bin
source /etc/profile
su - es
cd /data/elasticsearch/elasticsearch-head/
npm install
vim /data/elasticsearch/elasticsearch-head/Gruntfile.js
vim /data/elasticsearch/elasticsearch-head/_site/app.js
启动elasticsearch
su - es
/data/elasticsearch/bin/elasticsearch -d
启动 grunt
cd /data/elasticsearch/plugins/elasticsearch-head/node_modules/grunt/bin
# nohup ./grunt server &
访问 http://192.168.99.9:9100
安装kibana
Kibana是一个强大的es图形化组件,可以通过http的方式来查看es集群的状态,操作数据等.
当前es官方推荐的拓展组件为Kibana和X-Pack,而X-Pack需要依赖于Kibana.
下载地址：https://artifacts.elastic.co/downloads/kibana/kibana-5.5.0-linux-x86_64.tar.gz
选择任意一台es节点安装kibana
vim config/kibana.yml server.port: 5601 server.host: "192.168.10.116" elasticsearch.url: "http://192.168.99.8:9200"
xpack.security.enabled: false
在Kibana根目录运行 bin/kibana-plugin 进行安装
bin/kibana-plugin install x-pack
启动Kibana
启动之前需要禁用X-Pack 插件 security
vim config/kibana.yml
vim config/elasticsearch.yml
添加以下内容
xpack.security.enabled: false #重要
nginx 日志格式
log_format logstash_json '{ "@timestamp": "$time_local", ' '"client": "$remote_addr", ' '"hostname": "$hostname", ' '"remote_user": "$remote_user", ' '"upstream_addr": "$upstream_addr", ' '"upstream_response_time": "$upstream_response_time", ' '"body_bytes_sent": "$body_bytes_sent", ' '"request_time": "$request_time", ' '"status": "$status", ' '"request": "$request", ' '"request_method": "$request_method", ' '"http_referrer": "$http_referer", ' '"body_bytes_sent":"$body_bytes_sent", ' '"http_x_forwarded_for": "$http_x_forwarded_for", ' '"http_user_agent": "$http_user_agent" }'; access_log logs/access.log logstash_json;
filebeat 部署在nginx服务器上，收集日志
filebeat.prospectors: - input_type: log paths: - /data/nginx/logs/access.log document_type: nginx_access output.kafka: enabled : true hosts: ["kafka1:9092","kafka2:9092","kafka3:9092"] topic: logostash_%{[type]}
logstash 从kafka订阅消息，并存储到es中配置文件
input { kafka { bootstrap_servers => "kafka1:9092,kafka2:9092,kafka3:9092" topics => ["logostash__nginx_access"] consumer_threads => 5 decorate_events => true codec => "json" } } filter { json { remove_field => ["@timestamp","beat","type","kafka","domain","serverip","url","@version","offset","input_type","count","source","fields","beat.hostname","host","tags"] source => "message" remove_field => ["message"] } } output { elasticsearch { hosts => ["es1:9200","es2:9200","es3:9200"] manage_template => true index => "logstash-nginx.log-%{+YYYY-MM-dd}" } }
