master端:elasticsearch + logstash + redis + kibana
slave端:logstash + nginx or logstash + rsyslog
1.slave端收集nginx、syslog日志通过logstash写入到master上的redis中
2.master上的logstash读取redis中的日志输出到elastic,kibana再匹配读取elastic上内容
一、环境配置
1.安装jdk
tar zxf jdk-8u102-linux-x64.tar.gz
mv jdk1.8.0_102 /usr/local/java
cat /etc/profile
JAVA_HOME=/usr/local/java JRE_HOME=/usr/local/java/jre PATH=/usr/local/java/jre/bin:/usr/local/java/bin:$PATH CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar export JAVA_HOME JRE_HOME PATH CLASSPATH
source /etc/profile
2.安装redis
wget http://download.redis.io/releases/redis-3.2.3.tar.gz
tar zxf redis-3.2.3.tar.gz
cd redis-3.2.3
make
make install
./utils/install_server.sh
二、elasticsearch配置
1.安装elastic
tar zxf elasticsearch-2.4.0.tar.gz
cd elasticsearch-2.4.0
cat config/elasticsearch.yml #配置文件
cluster.name: elk-test #配置集群名称(加入同一个集群名称要一样) node.name: server-102 #配置节点名称 node.master: true #配置是否作为主节点(默认为true) node.data: true #配置是否为数据节点(默认为true) path.data: /data/ela/data #配置数据路径 path.logs: /data/ela/logs #配置日志路径 bootstrap.memory_lock: true #锁住内存不让内存在swap中使用 network.host: 172.16.0.102 #配置绑定ip地址(默认为0.0.0.0) http.port: 9200 #配置端口号 node.max_local_storage_nodes: 1 #配置启动1个节点 index.number_of_shards: 5 #配置索引碎片的数量(默认为5) discovery.zen.minimum_master_nodes: 1 #配置集群中主节点的数量(当节点大于三个时候可配置2-4) discovery.zen.ping.timeout: 5s #配置连接其他节点的超时时间 discovery.zen.ping.multicast.enabled: false #配置允许发现多个集群节点(默认为true禁止) discovery.zen.ping.unicast.hosts: ["host1", "host2:port", "host3:port"] #配置新节点被启动时能够发现的主节点列表
mkdir -p /data/ela/data /data/ela/logs
useradd elk
chown -R elk.elk /data/ela/data /data/ela/logs /data/elasticsearch-2.4.0
/data/elasticsearch-2.4.0/bin/elasticsearch (elastic默认不能使用root启动使用-Des.insecure.allow.root=true参数以root启动)
2.安装插件
Head插件(节点数据查看管理)
./elasticsearch/bin/plugin install mobz/elasticsearch-head
Kopf插件(集群管理)
./elasticsearch/bin/plugin install lmenezes/elasticsearch-kopf
Bigdesk插件(监控查看CPU内存索引数据搜索情况http连接数)
./elasticsearch/bin/plugin install hlstudio/bigdesk
Marvel插件(管理和监控,通过kibana上访问插件)
./elasticsearch/bin/plugin install license
./elasticsearch/bin/plugin install marvel-agent
./kiabana/bin/kibana plugin --install elasticsearch/marvel/latest
三、logstash配置
安装logstash
wget https://download.elastic.co/logstash/logstash/logstash-2.4.0.tar.gz
tar zxf logstash-2.4.0.tar.gz
cd logstash-2.4.0
vim config/logstash.conf #新建配置master端的文件
#读取redis里的日志 input { redis { host => "100.100.100.102" data_type => "list" key => "logstash:redis" type => "redis-input" } } #过滤掉内容包含5.3.3与down以外日志 filter { if [message] !~ "5.3.3|down" { ruby { code => "event.cancel" } } } #使用自带的过滤规则显示更多的字段 filter { grok { match => {"message" => "%{COMBINEDAPACHELOG}"} } } #合并不是以[开头的日志 filter { multiline { pattern => "^[^[]" negate => true what => "previous" } } #输出到elastic并建立索引 output { if [type] == "syslog" { elasticsearch { hosts => "172.16.0.102:9200" index => "syslog-%{+YYYY.MM.dd}" } } if [type] == "nginx" { elasticsearch { hosts => "172.16.0.102:9200" index => "nglog-%{+YYYY.MM.dd}" } } #匹配内容包含paramiko与simplejson的日志通邮件发送 if [message] =~ /paramiko|simplejson/ { email { to => "[email protected]" from => "[email protected]" contenttype => "text/plain; charset=UTF-8" address => "smtp.163.com" username => "[email protected]" password => "12344" subject => "服务器%{host}日志异常" body => "%{@timestamp} %{type}: %{message}" } } }
./bin/logstash -f config/logstash-slave.conf #启动master端logstash
vim config/logstash.conf #新建配置slave端的文件(安装过程与master一样)
#收集nginx与系统日志 input { file { type => "nginx" path => "/usr/local/nginx/logs/access.log" add_field => {"ip"=>"100.100.100.100"} start_position => "beginning" #从文件头开始读取 } syslog { type => "syslog" host => "100.100.100.100" port => "514" } file { type=> "syslog" path => "/var/log/messages" } } #输出日志到master端的redis中 output { redis { host => "100.100.100.102" port => "6379" data_type => "list" key => "logstash:redis" } }
./bin/logstash -f config/logstash-slave.conf #启动slave端logstash
四、kibana配置
1.安装kibana
wget https://download.elastic.co/kibana/kibana/kibana-4.6.1-linux-x86_64.tar.gz
tar zxf kibana-4.6.1-linux-x86_64.tar.gz
cd kibana-4.6.1-linux-x86_64
cat config/kibana.yml
server.port: 5601 #端口 server.host: "172.16.0.102" #访问ip地址 elasticsearch.url: "http://172.16.0.102:9200" #连接elastic kibana.index: ".kibana" #在elastic中添加.kibana索引
./bin/kibana
