Sodobni svet sistemskih administratorjev nas je razvadil z lepimi spletnimi vmesniki, da se nam niti ne ljubi name\u0161\u010dati programske opreme, kjer ni tega \u00bbGUI\u00ab (\u010dutim, da me bodo zdaj napadli pravi\u010dno razburjeni programerji), saj res ni treba nenehno posegati po ukazni vrstici, kajne? Vse bi bilo v redu, \u010de bi programsko opremo namestil, konfiguriral in pozabil, a kaj storiti, \u010de je potrebno nenehno posegati, urejati in seveda ni dnevnika vseh dejanj \u2013 ali pa\u010d ni treba vsaki\u010d pisati cp cfg cfg_back, s\u010dasoma se lahko zmeden in opusti\u0161 to nalogo.<\/p>\n

\nPred mnogo leti sem se spoznal s \u010dudovitim uravnote\u017eevalnikom, kot je Haproxy. Vse je bilo \u010dudovito in lepo. Imel sem jih veliko in sem za\u010del razmi\u0161ljati o iskanju GUI zanj, a ga na presene\u010denje ni bilo. Tako priljubljena programska oprema, pa \u0161e povsem stara, no, pa sem si rekel in nadaljeval ob\u010dasno ro\u010dno urejanje v svojem najljub\u0161em vi in imel kup odprtih zavihkov s statistiko vseh aktivnih. stre\u017enikov<\/a>. A pri\u0161el je \u010das, ko sem moral zadovoljevati \u00bb\u017eelje\u00ab ljudi, ki so pisali programsko opremo za delo prek http, in tukaj se je za\u010delo zanimivo \u2026 <\/p>\n

Roke so se mi zasrbeli, o\u010di so mi zasvetile in sem se lotil dela. Natan\u010dneje, za\u010del sem razmi\u0161ljati, v \u010dem naj pi\u0161em, spominjati se dolgo pozabljenega PHP, a nekako se mi ni ljubilo, pa se mi je zdelo, da ni ravno primeren za to nalogo. Na koncu je izbira padla na Python, v prihodnosti se bo zagotovo izkazalo za koristno, sem pomislil, in za\u010delo se je vpijanje informacij.<\/p>\n

Na za\u010detku naloge niso bile tako zelo zapletene: mo\u017enost urejanja konfiguracij iz spletnega vmesnika iz ene to\u010dke dostopa, shranjevanje prej\u0161njih razli\u010dic konfiguracij. Ta, ne ravno obse\u017een funkcionalnost, je bila uresni\u010dena dokaj hitro, vendar je v meni vzklila ali lenoba administratorja ali prekleto perfekcionizem in mi je bilo seveda tega malo. Takrat so za\u010dele nastajati lastnosti, kot so: primerjanje dveh konfiguracij, bele\u017eenje vseh dejanj v zvezi s konfiguracijami, Runtime API in dodajanje sekcij prek spleta.<\/p>\n

\"Kako<\/a><\/noindex><\/p>\n

In kot pravi UNIX administrator, ki \u017eivi od prostega programske opreme, sem se odlo\u010dil deliti z svetom, morda bo komu koristilo? A za to je bilo potrebno narediti vse tako, da ni bilo treba posegati v kodo, ampak najve\u010d v konfiguracijske datoteke (trenutno je ve\u010dina nastavitev pre\u0161la v bazo. Po mojem mnenju je to postalo bolj priro\u010dno za urejanje in ob posodabljanju ne bo napak zaradi manjkajo\u010dega parametra v konfiguraciji). <\/p>\n

Mesec dni po tem, ko sem svoj projekt nalo\u017eil na Github, brez posebnih pri\u010dakovanj, se je izkazalo, da je programska oprema nekoliko povpra\u0161evana in za\u010delo se je najbolj zanimivo... Aktivno \"dopolnjevanje\" poteka \u017ee skoraj leto. Ob\u010dasno imam \u017eeljo, da vse to pustim, saj so moje potrebe \u017ee davno zadovoljene. Kaj mi pomaga mo\u017enost postavitve \"klastra\" z keepalived in HAProxy preko spletnega vmesnika, \u010de mi to vzame najve\u010d nekaj minut? O\u010ditno pa ljudem to bermagaja, tudi meni je zanimivo, in je nekaj dela. Seveda pa obstajajo tudi funkcije, ki so mi potrebne, na primer, kako spremljati backend stre\u017enike, ali so na voljo za Haproxy. Imamo seveda korporativno spremljanje, ampak tam so ljudje, ki lahko kar nekaj \u010dasa reagirajo, + ker se moje podro\u010dje ukvarja z razvojem in programska oprema se pojavlja in izgine, se moram kar dolgo prebiti skozi birokracijo.<\/p>\n

\"Kako<\/a><\/noindex><\/p>\n

Na kratko sem se odlo\u010dil deliti, saj se izka\u017ee, da je to edini brezpla\u010dni GUI. Morda bo komu pri\u0161lo prav? Povezava do GitHub-a<\/a><\/noindex>.
