You can use the json input type in Filebeat to send JSON logs to Elasticsearch. Here is an example of how you can configure Filebeat to send JSON logs to Elasticsearch 1:

filebeat.inputs:
- type: log
  enabled: true
  paths:
    - /var/log/*.json
  json.keys_under_root: true
  json.add_error_key: true

output.elasticsearch:
  hosts: ["localhost:9200"]
  index: "myindex-%{+yyyy.MM.dd}"


Here is an example of a docker-compose file for

 Filebeat, Elasticsearch and Kibana with password :

version: '3.7'
services:
  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.16.2
    container_name: elasticsearch
    environment:
      - node.name=elasticsearch
      - cluster.name=elasticsearch-cluster

      - cluster.initial_master_nodes=elasticsearch
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
      - ELASTIC_PASSWORD=changeme
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - esdata1:/usr/share/elasticsearch/data
    ports:
      - 9200:9200

  kibana:
    image: docker.elastic.co/kibana/kibana:7.16.2
    container_name: kibana

      ELASTICSEARCH_HOSTS: http://elasticsearch:9200
      ELASTICSEARCH_USERNAME: elastic
      ELASTICSEARCH_PASSWORD: changeme
    ports:
      - 5601:5601

  filebeat:
    image: docker.elastic.co/beats/filebeat:7.16.2
    container_name: filebeat
    user: root
    volumes:
      - ./filebeat.yml:/usr/share/filebeat/filebeat.yml
      - /var/lib/docker/containers:/var/lib/docker/containers
    command: filebeat -e --strict.perms=false

لاگ کردن در کنسول با فرمت Json

To print logs in JSON format with SLF4J in Spring Boot, you can use Logback as the logging framework. You can add the following dependencies to your pom.xml file:


<dependency>
    <groupId>net.logstash.logback</groupId>
    <artifactId>logstash-logback-encoder</artifactId>
    <version>6.6</version>
</dependency>

To cache Next.js pages in Spring Cloud Gateway, you can use Spring Cache and Caffeine. You can write a filter that caches the response for specific requests. Here is an example of how to do it:



@Component
@Slf4j
public class CacheResponseGatewayFilterFactory extends AbstractGatewayFilterFactory<CacheResponseGatewayFilterFactory.Config> {

    public CacheResponseGatewayFilterFactory() {
        super(Config.class);
    }

    @Override
    public GatewayFilter apply(Config config) {
        return (exchange, chain) -> {
            String cacheKey = exchange.getRequest().getURI().toString();
            Cache.ValueWrapper
cachedResponse = cacheManager.getCache("myCache").get(cacheKey);
            if (cachedResponse != null) {
                log.info("Returning cached response for {}", cacheKey);
                return Mono.just(cachedResponse.get());
            }
            return chain.filter(exchange).doOnNext(response -> {
                if (response.getStatusCode().is2xxSuccessful()) {
                    log.info("Caching response for {}", cacheKey);
                    cacheManager.getCache("myCache").put(cacheKey, response);
                }
            });
};
    }

    public static class Config {
        // Put the configuration properties here
    }

}

remove java

  1. Remove all the Java related packages (Sun, Oracle, OpenJDK, IcedTea plugins, GIJ):

    dpkg-query -W -f='${binary:Package}\n' | grep -E -e '^(ia32-)?(sun|oracle)-java' -e '^openjdk-' -e '^icedtea' -e '^(default|gcj)-j(re|dk)' -e '^gcj-(.*)-j(re|dk)' -e '^java-common' | xargs sudo apt-get -y remove
    sudo apt-get -y autoremove
  2. Purge config files (careful. This command removed libsgutils2-2 and virtualbox config files too):

    dpkg -l | grep ^rc | awk '{print($2)}' | xargs sudo apt-get -y purge
  3. Remove Java config and cache directory:

    sudo bash -c 'ls -d /home/*/.java' | xargs sudo rm -rf
  4. Remove manually installed JVMs:

    sudo rm -rf /usr/lib/jvm/*
  5. Remove Java entries, if there is still any, from the alternatives:

    for g in ControlPanel java java_vm javaws jcontrol jexec keytool mozilla-javaplugin.so orbd pack200 policytool rmid rmiregistry servertool tnameserv unpack200 appletviewer apt extcheck HtmlConverter idlj jar jarsigner javac javadoc javah javap jconsole jdb jhat jinfo jmap jps jrunscript jsadebugd jstack jstat jstatd native2ascii rmic schemagen serialver wsgen wsimport xjc xulrunner-1.9-javaplugin.so; do sudo update-alternatives --remove-all $g; done
  6. Search for possible remaining Java directories:

    sudo updatedb
    sudo locate -b '\pack200'

    If the command above produces any output like /path/to/jre1.6.0_34/bin/pack200 remove the directory that is parent of bin, like this: sudo rm -rf /path/to/jre1.6.0_34.

انتقال فایل بین دو سرور

ابتدا نیاز است که فایل ها رو فشرده کنیم تا سرعت انتقال افزایش یابد.

با استفاده از دستور زیر پوشه جاری فشرده میشود


# tar cvzf backup.tar.gz /var/www


سپس با استفاده از دستور زیر فایل را به سرور مورد نظر انتقال میدهیم



Copy the file "foobar.txt" from a remote host to the local host

$ scp your_username@remotehost.edu:foobar.txt /some/local/directory


Copy the file "foobar.txt" from the local host to a remote host

$ scp foobar.txt your_username@remotehost.edu:/some/remote/directory


Copy the directory "foo" from the local host to a remote host's directory "bar"

$ scp -r foo your_username@remotehost.edu:/some/remote/directory/bar


Copy the file "foobar.txt" from remote host "rh1.edu" to remote host "rh2.edu"

$ scp your_username@rh1.edu:/some/remote/directory/foobar.txt \

your_username@rh2.edu:/some/remote/directory/


Copying the files "foo.txt" and "bar.txt" from the local host to your home directory on the remote host

$ scp foo.txt bar.txt your_username@remotehost.edu:~


Copy the file "foobar.txt" from the local host to a remote host using port 2264

$ scp -P 2264 foobar.txt your_username@remotehost.edu:/some/remote/directory


Copy multiple files from the remote host to your current directory on the local host

$ scp your_username@remotehost.edu:/some/remote/directory/\{a,b,c\} .

$ scp your_username@remotehost.edu:~/\{foo.txt,bar.txt\} .


سپس با استفاده از دستور زیر محتوای فایل فشرده را استخراج میکنیم


# tar -xzf backup.tar.gz
