\u00d6ncelikle, sisteminizin g\u00fcncel oldu\u011fundan emin olun ve gerekli baz\u0131 ara\u00e7lar\u0131 y\u00fckleyin:<\/p>\n

          Consul hangi portlar\u0131 kullan\u0131r?<\/dt>\n
          Temel olarak 8300 (sunucu RPC), 8301 (LAN gossip), 8302 (WAN gossip), 8500 (HTTP API\/UI) ve 8600 (DNS) portlar\u0131n\u0131 kullan\u0131r. G\u00fcvenlik duvar\u0131n\u0131zda bu portlar\u0131 a\u00e7man\u0131z gerekir.<\/dd>\n
          Sunucu ve istemci aras\u0131ndaki fark nedir?<\/dt>\n
          Consul sunucular\u0131, k\u00fcmenin durumunu korur, RAFT konsens\u00fcs\u00fcn\u00fc \u00e7al\u0131\u015ft\u0131r\u0131r ve t\u00fcm veriyi depolar. \u0130stemciler ise hizmetleri kaydeden, sa\u011fl\u0131k kontrolleri yapan ve sunuculara proxy g\u00f6revi g\u00f6ren hafif d\u00fc\u011f\u00fcmlerdir.<\/dd>\n
          bootstrap_expect<\/code> neden \u00f6nemlidir?<\/dt>\n
          Bu parametre, bir Consul k\u00fcmesinin ilk kez ba\u015flat\u0131lmas\u0131 s\u0131ras\u0131nda beklenen sunucu say\u0131s\u0131n\u0131 belirtir. Yanl\u0131\u015f ayarlanmas\u0131, k\u00fcmenin kilitlenmesine veya veri kayb\u0131na yol a\u00e7abilir. K\u00fcme ba\u015flat\u0131ld\u0131ktan sonra de\u011fi\u015ftirilmemelidir.<\/dd>\n

          Consul’u izlemek i\u00e7in ne yapmal\u0131y\u0131m?<\/dt>\n
          Consul UI, consul members<\/code> ve consul operator raft list-peers<\/code> komutlar\u0131 ile k\u00fcme sa\u011fl\u0131\u011f\u0131n\u0131 izleyebilirsiniz.
