Eu tenho um arquivo que contém um monte de cron jobs:

30 * * * * someexec somefile
30 1 * * * someexec somefile
30 5 * * * someexec somefile

Eu gostaria que, quando esses trabalhos cron fossem ativados, algo na forma de "trabalho Cron someexec somfile foi iniciado" no arquivo de log, /var/log/cronjobs.logpor exemplo.

Eu não quero registrar o que esses cron jobs ecoam quando são executados, pois já consertei isso. Eu só quero registrar que os trabalhos estão ativos.

letsencrypt.service:

[Unit]
Description=Renews letsencrypt certificates
After=network.target letsencrypt_concat_fullchain_privkey.service

[Service]
Type=oneshot
WorkingDirectory=/etc/letsencrypt/
ExecStart=/usr/bin/letsencrypt renew

Quando inicio este serviço manualmente: sudo systemctl start letsencryptparece que não inicia o letsencrypt_concat_fullchain_privkey.serviceserviço. Eu corri sudo systemctl start letsencrypt_concat_fullchain_privkey.servicee funciona como deveria.

O que estou tentando fazer é que quando letsencrypt.serviceterminar gostaria que iniciasse o letsencrypt_concat_fullchain_privkey.serviceserviço.

Inicie o container com isso:docker run --name development-karl -h development-karl -d x/x:x

parte do meu haproxy.cfg:

backend karl_dev_backend
    balance roundrobin
    option forwardfor
    server      karl_dev development-karl cookie development-karl weight 1 maxconn 1024 check

Obtenha o erro nos logs do haproxy:

Não sei porque não resolve?

O Docker não oferece suporte à descoberta automática de serviço na rede de ponte padrão. Se você deseja se comunicar com nomes de contêineres nessa rede de ponte padrão, deve conectar os contêineres por meio da opção legado docker run --link.

O legado é anterior à versão 1.10.

Estou executando um contêiner docker com uma pilha ELK. Tudo está funcionando perfeitamente e bem. Eu gostaria de utilizar o plug-in https://www.elastic.co/guide/en/logstash/current/plugins-outputs-http.html .

Eu instalo o plugin nele:

root@elk:/# /opt/logstash/bin/plugin install logstash-output-http
Validating logstash-output-http
Installing logstash-output-http
Installation successful

/etc/logstash/conf.d/logstash.confarquivo de configuração principal do logstash:

input {
  beats {
   port => 5044
   type => "logs"
  }
}
filter {
  grok {
    match => { "message" => "\"name\":\"Error\""}
    add_tag => ["error"]
  }
}
output {
  elasticsearch {
    hosts => "localhost:9200"
    sniffing => true
    manage_template => false
    index => "%{[@metadata][beat]}-%{+YYYY.MM.dd}"
    document_type => "%{[@metadata][type]}"
  }
  if "error" in [tags] {
    http {
      http_method => "post"
      url => "https://hooks.slack.com/services/<MY_ID>"
      format => "json"
      content_type => "application/json"
      message => "{\"text\": \"dis is workinz\"}"
    }
  }
}

Eu também tentei mudar o formato no http:

...
format => "message"
...

A configuração também é testada e é válida:

root@elk:/# /opt/logstash/bin/logstash --configtest -f /etc/logstash/conf.d/logstash.conf 
Configuration OK

Ambos resultam em não funcionar. Eu verifiquei duas vezes para ter certeza de que o webhook está funcionando com um teste (do contêiner do docker logstash):

curl -H "Content-Type: application/json" -X POST -d '{"text":"testing"}' https://hooks.slack.com/services/<MY_ID>

Sei que as tags estão sendo aplicadas corretamente, verificadas no Kibana. Além disso, a cláusula if também está funcionando, pois testei colocando elasticsearchdentro dela e, de fato, apenas enviou logs com as errortags adicionadas para elasticsearch.

Por fim, a sagrada mensagem de erro de /var/log/logstash/logstah.log:

Desejo usar Gmailpara lidar com todas as minhas necessidades de e-mail. Enviando, lendo, excluindo, movendo, encaminhando etc. Eu tenho um domínio com um e-mail em Zoho [email protected], está funcionando bem.

Sempre fiquei confuso sobre POP3qual IMAPservidor/cliente faz o quê. Leitura Qual é a diferença entre POP3 e IMAP para e-mail? realmente não me deixou mais inteligente.

Aqui está um fluxo do e-mail do [email protected]qual eu gostaria:

E-mail de entrada (para: [email protected]) -> caixa de entrada Zoho ([email protected]) -> conta do Gmail ([email protected]) -> cliente Android/navegador da Web

Também gostaria de enviar:

Cliente Android/navegador da Web -> Conta do Gmail(usuá[email protected]) -> Conta Zoho(usuário@meudomínio.com) -> Enviar e-mail(de: usuário@meudomínio.com)

Também gostaria de configurar para que via Gmail eu possa enviar e-mails via [email protected].

Você pode dizer que Gmailé central. Como eu configuraria isso? Eu estou supondo que é melhor usar IMAPcomo POP3está velho. Também gostaria de manter cópias Zohoque não sejam afetadas pelo Gmail, portanto, se eu excluir uma mensagem no Gmail que foi para [email protected]ela, não será excluída Zoho(use Zohocomo backup).

Qual deve ser o IMAP/ POP3server neste caso?

ZohoGenericName

POPDetalhes da configuração:

  • Servidor de entrada: pop.zoho.com, Porta: 995, SSL
  • Servidor de saída: smtp.zoho.com, Porta: 465, SSL

IMAPDetalhes da configuração:

  • Servidor de entrada: imap.zoho.com, Porta: 993, SSL
  • Servidor de saída: smtp.zoho.com, Porta: 465, SSL

Gmail

Servidor de entrada de correio ( IMAP) - requer SSL

  • imap.gmail.com Porta: 993 Requer SSL:Sim

Servidor de e- mail de saída ( SMTP) - requer TLS

  • smtp.gmail.com Porta: 465 ou 587 Requer SSL: Sim Requer autenticação: Sim Use as mesmas configurações do servidor de e-mail de entrada

Entrada x Saída no Zoho

  1. Entrada: isso significa que o Gmail envia de seu servidor de saída para o servidor de entrada do Zohos?
  2. Saída: Zoho para enviar de seu servidor de saída para o servidor de entrada do Gmail?

Entrada x Saída no Gmail

  1. Entrada: isso significa que meu cliente/navegador da web Android deve enviar para o servidor de entrada do Gmail?
  2. Saída: servidor de saída do Gmail para enviar para o servidor de entrada Zohos?

O que eu faço no Zoho e o que eu faço no Gmail?
