启动准备
elasticsearch
设置jvm.options,
-XX:ParallelGCThreads=3 #3可修改
elasticsearch 不能用root启动;
groupadd elsearch
useradd elsearch -g elsearch -p elasticsearch
su elsearch
修改 /etc/security/limits.conf, 增加:
elsearch soft nofile 819200
elsearch hard nofile 819200
elsearch soft nproc 2048
elsearch hard nproc 4096
elsearch soft memlock unlimited
elsearch hard memlock unlimited
修改 /etc/security/limits.d/90-nproc.conf:
* soft nproc 1024
修改为
* soft nproc 2048
修改 /etc/sysctl.conf。如果在docker中,修改/etc/sysctl.conf文件,需要--privileged权限。:
vm.max_map_count=655360
这个文件修改后,需要执行:
sysctl -p
修改配置文件 config/elasticsearch.yml
cluster.name: myes
node.name: abcdocker-node-1
path.data: /home/worker/data/www/src/data/es-date
path.logs: /home/worker/data/www/src/logs/elasticsearch
bootstrap.memory_lock: true
network.host: 172.17.0.2
http.port: 9200
logstash
设置jvm.options,
-XX:ParallelGCThreads=3 #3可修改
kibana
启动前,需设置elasticsearch访问端口
修改配置文件 config/kibana.yml
elasticsearch.url: "http://172.17.0.2:9200"
server.port: 80
启动命令
elasticsearch
进入elasticsearch的bin目录:
./elasticsearch -d
-d参数是后台运行
logstash
bin/logstash -e 'input { stdin{} } output { stdout{ codec => rubydebug} }'
写入elasticsearch
bin/logstash -e 'input { stdin{} } output { stdout{ codec => rubydebug} elasticsearch { hosts => ["172.17.0.2:9200"] index => "logstash-%{+YYYY.MM.dd}" } }'
可用配置文件方式,配置文件内容:
input{
file{
path => ["/home/worker/data/www/runtime/demo/err.log"]
type => "system-log"
start_position => "beginning"
}
stdinP{}
}
filter{
}
output{
elasticsearch{
hosts => ["172.17.0.1:9200"]
index => "logstash-%{+YYYY.MM.dd}"
}
stdout{
codec=>rubydebug
}
}
启动方式:
bin/logstash -f /etc/logstash/conf.d/file.conf
kibana
bin/kibana
