ERR_CONNECTION_REFUSED

smigis

Kadangi viršijome Inode resursus bei buvo aktualu, kad vienu metu būtų vykdomi keli PHP procesai užsisakėme planą Linux 16 su DirectAdmin 1.6 (Centos 7) diegimu. Perkelėme svetainį į serverį, įdiegėme Let's Encrypt. Svetainė veikia, tačiau susidūrėme su problema, kad labai dažnai svetainė nepasiekiama - ERR_CONNECTION_REFUSED. Neturime patirties administruoti serverio. Norėtume išgirsti patarimų, kaip būtų galima išspręsti šią problemą.

Laba diena,

Detalesnei situacijos analizei siūlytume pateikti užklausą el. paštu info@dedikuoti.lt nurodant svetainės pavadinimą ir trumpai aprašant problemą. Iš informacijos, kurią suteikėte neturime galimybės identifikuoti galimos problemos priežasties, nes ši klaida gali būti pateikiama dėl daugelio įvairių priežasčių.

smigis

Suprantame, kad dedikuoti serveriai yra administruojami savarankiškai, ir nekeliame jokių pretenzijų. Tiesiog forume tikimės patarimų, kadangi, kaip minėjome, neturime patirties administruoti serverio. Taip pat suprantame, kad priežasčių gali būti daug. Rašome į forumą, tikėdamiesi ne tik paslaugos teikėjų atsakymo, bet kitų forumo dalyvių įžvalgų.
Svetainės adresas: www.ratai4.lt. Svetainė perkelta iš kito serverio, yra prarastų nuotraukų, bet, manytume, kad tai neturėtų įtakoti.
Pridedame Apache klaidų sąrašą:

Laba diena,

Didžioji dauguma klaidų nedaro įtakos svetainės neveikimui, tai tik pranešimai ar perspėjimai dėl galimų problemų, tokie kaip:

[Mon Feb 08 23:06:42.140761 2021] [ssl:warn] [pid 25836:tid 140471298455680] AH01909: www.example.com:443:0 server certificate does NOT include an ID which matches the server name

Tačiau kitos klaidos, tokios kaip:

[Mon Feb 08 23:06:42.141190 2021] [core:warn] [pid 25836:tid 140471298455680] AH00098: pid file /var/run/httpd.pid overwritten -- Unclean shutdown of previous Apache run?

Sudaro vaizdą, kad problema su Apache konfigūracija. Galbūt galite patikslinti ar Apache konfigūravote patys ar naudojate, kurį nors iš mūsų sukurtų serverio valdymo pultų šablonų?

smigis

Sveiki. Ačiū, kad pakomentavote. Užsakėme serverį su Centos 7 ir Directadmin diegimu. 

smigis

Patys įsidiegėme Let's Encrypt sertifikatą bei dvi PHP versijas (pagal šią instrukciją https://forumas.dedikuoti.lt/discussion/724/keliu-skirtingu-php-versiju-naudojimas-directadmin-valdymo-pulte). Apache konfigūracijos lyg ir nekeitėme.
Taip pat kas valandą gauname pranešimus: "The service 'httpd' on server kpgi.c.dedikuoti.lt is currently down".

iv_vytenisg

Peržiūrėjus galimas problemas pagal klaidą internete, aptinkame, kad siūloma paleisti šias komandas terminale, kurios padės perkonfigūruoti Apache bei PHP:

./build apache
./build php
./build rewrite_confs

Tik norime papildomai perspėti, kad negalime garantuoti jog siūlomas sprendimas pašalins problemą.

smigis

Esam labai dėkingi, Vyteni. Padėjo.
