ncnetcat命令是一个功能强大的网络工具用于在网络连接上进行读写数据。它可以在 TCP 或 UDP 协议下工作被广泛用于网络调试、端口扫描、数据传输等多种任务1.启动第一个实例
[11:29:55 rootelk2:/etc/logstash/conf.d]#logstash -f 01-stdin-to-stdout.conf2.启动第二个实例
[10:36:25 rootelk2:/etc/logstash/conf.d]#logstash -f 02-file-to-stdout.conf --path.data /tmp/logstash-data#注意实验事项
1.如果不指定数据路径则Logstash默认的数据路径在安装目录的data目录下。比如: /usr/share/logstash/data/
2.如果同一个节点启动了多个Logstash实例不指定数据路径则会报错Logstash could not be started because there is already another instance using the configured data directory. If you wish to run multiple instances, you must change the path.data setting.------------------------------实验开始位置----------------------------------------- 1.启动Logstash实例1

}JVM优化
1.查看Logstash实例启动时占用的heap堆内存大小
[16:15:05 rootelk2:~]#ps -ef | grep logstash
root 2026 1053 99 16:15 pts/0 00:00:36 /usr/share/elasticsearch/jdk/bin/java -Xms1g -Xmx1g2.修改Logstash的堆内存大小
[16:15:02 rootelk2:~]#vim /etc/logstash/jvm.options
## JVM configuration# Xms represents the initial size of total heap space
# Xmx represents the maximum size of total heap space#-Xms1g
#-Xmx1g-Xms256m
-Xmx256m3.启动Logstash实例测试
[16:14:53 rootelk2:/etc/logstash/conf.d]#logstash -rf 14-tcp-grok_custom_patter4.查看JVM占用内存情况
[16:16:57 rootelk2:~]#ps -ef | grep logstash
root 2123 1053 99 16:17 pts/0 00:00:05 /usr/share/elasticsearch/jdk/bin/java -Xms128m -Xmx128m#注意出现java.lang.OutOfMemoryError: Java heap space
表示内存不足仅需要添加内存即可工作中如何不设置Logstash的堆内存大小默认为1GB。自定义Nginx的json日志格式
1.清空nginx访问日志
[16:38:12 rootelk3:~]# /var/log/nginx/access.log2.修改nginx的配置文件
[16:38:13 rootelk3:~]#vim /etc/nginx/nginx.conf ...# 注释原有的配置行# access_log /var/log/nginx/access.log;log_format nginx_json {timestamp:$time_iso8601,host:$server_addr,clientip:$remote_addr,SendBytes:$body_bytes_sent,responsetime:$request_time,upstreamtime:$upstream_response_time,upstreamhost:$upstream_addr,http_host:$host,uri:$uri,domain:$host,xff:$http_x_forwarded_for,referer:$http_referer,tcp_xff:$proxy_protocol_addr,http_user_agent:$http_user_agent,status:$status};access_log /var/log/nginx/access.log nginx_json;

- 堆内存- 伊甸区表示对象产生的内存。- 幸存区经过GC时在伊甸区没有结束生命周期的对象会经过幸存区过滤到年老区。- 年老区长期存在的对象。项目篇: ElasticStack的RBAC实战
2.配置ES集群加密
2.1 生成证书文件

Note: Generating certificates without providing a CA certificate is deprecated.A CA certificate will become mandatory in the next major release.Certificates written to /etc/elasticsearch/elastic-certificates.p12This file should be properly secured as it contains the private key for
your instance.This file is a self contained file and can be copied and used as is
For each Elastic product that you wish to configure, you should copy
this .p12 file to the relevant configuration directory
and then follow the SSL configuration instructions in the product guide.[17:33:28 rootelk1:~]#ll /etc/elasticsearch/elastic-certificates.p12
