Kaasaegne s\u00fcsteemihaldurite maailm on meid harjutanud ilusate veebiliidesega, et isegi ei taha installeerida tarkvara, kus pole seda \u00abgui\u00bb (tunnen, et n\u00fc\u00fcd lendavad kivide sadu \u00f5igeusklikelt skriptiderikultelt). No ei saa ju pidevalt k\u00e4sureale ronida, eks? K\u00f5ik oleks h\u00e4sti, kui paned tarkvara paika, seadistad ja unustad, aga mis siis, kui sinna tuleb pidevalt sisse minna, muuta ning loomulikult puudub tegevuste logi \u2014 ei hakka ju iga kord kirjutama cp cfg cfg_back, aja jooksul segad end \u00e4ra ja loobud sellest asjast.<\/p>\n

\n<\/a><\/noindex>
\nPalju aastaid tagasi tutvusin ma sellise imelise tasakaalustajaga nagu Haproxy. K\u00f5ik on suurep\u00e4rane ja ilus. N\u00fc\u00fcd on mul neid palju ja hakkasin otsima GUI-d sellele, aga \u00fcllataval kombel ei leidnud. V\u00e4ga populaarne tarkvara, lisaks veel piisavalt vana, aga las olla, m\u00f5tlesin ja j\u00e4tkasin aeg-ajalt k\u00e4tega seda oma lemmik vi-s muutmist ning avasin hunniku sakkide statistika jaoks, mis sisaldab k\u00f5iki aktiivseid. serverite<\/a>. Aga tuli aeg, mil pidin rahuldama inimeste \u00absoove\u00bb, kes kirjutasid tarkvara t\u00f6\u00f6ks http kaudu, siin see huvitav asi algas\u2026 <\/p>\n

K\u00e4ed s\u00fcgelevad, silmad s\u00e4delevad ja ma alustasin. T\u00e4psemalt, hakkasin m\u00f5tlema, millega kirjutada \u2014 meenutama ammuseid PHP teadmisi, mis kuidagi ei kutsunud, ja tundus, et see ei sobi k\u00f5ige paremaks lahenduseks. L\u00f5puks langes valik Pythonile; m\u00f5tlesin, et see tuleb tulevikus kindlasti kasuks, ja info omandamine algas.<\/p>\n

\u00dcmberringi ei olnud alguses sugugi keerulised \u00fclesanded: v\u00f5imalik oli konfigureerida seadeid veebivahendi kaudu \u00fchest sisenemispunktist, talletades eelmised versioonid konfiguratsioonidest. See, mitte just suur funktsionaalsus, \u00f5nnestus kiiresti ellu viia, kuid siis hakkas minus m\u00e4ngima kas administraatori laiskus v\u00f5i kuulsa perfektsionismi tunne ja sellest tundus muidugi v\u00e4he. Siis hakkasid ilmnema sellised funktsioonid nagu: kahe konfiguratsiooni v\u00f5rdlemine, k\u00f5iki konfiguratsioonidega seotud toimingute logimine, Runtime API ja sektsioonide lisamine veebiteel.<\/p>\n

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

Ja kui korrektselt \u00fctlen, siis UNIX administraatorina, kes elab vaba tarkvara toel, otsustasin jagada seda maailmaga \u2013 \u00e4kki on kellelegi sellest kasu? Kuid selleks tuli k\u00f5ik teha nii, et poleks vaja koodi vaadata, vaid maksimaalselt konfigureerimist (Praegu on enamus seadeid liikunud andmebaasi. Minu jaoks on neid lihtsam muuta, ja v\u00e4rskendamise ajal ei esine vigu, sest m\u00f5ni parameeter puudub konfiguratsioonist). <\/p>\n

Aeg p\u00e4rast laadisin oma projekti Githubi, lootes mitte millegile. Kahjuks osutus tarkvara veidi n\u00f5utuks ja siis algas k\u00f5ige huvitavam osa... Aktiivne areng on kestnud juba peaaegu aasta. M\u00f5nikord on tahtmine k\u00f5ik katki j\u00e4tta, kuna minu vajadused on juba ammu rahuldatud. Mis m\u00f5tet on mul k\u00e4ivitada \u00abkluster\u00bb keepalivedi ja HAProxy kaudu, kui see v\u00f5tab mul aega vaid paar minutit? Sellegipoolest on see inimestele vajalik, ja ka minul on huvi ning tegemist peaaegu alati. Kuigi loomulikult on ka funktsioonid, mis on mulle vajalikud, n\u00e4iteks kuidas j\u00e4lgida tagaplaneedi serverite k\u00e4ttesaadavust Haproxy jaoks. Meil on muidugi ettev\u00f5ttesisene j\u00e4lgimine, kuid seal on inimesi, kes v\u00f5ivad reageerida \u00fcsna pikalt, pluss kuna minu osakond tegeleb arendusega ja tarkvara tuleb ja kaob, on b\u00fcrokraatiast l\u00e4bi murdmine aegan\u00f5udev.<\/p>\n

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

Otsustasin jagada, sest tundub, et see on ainus tasuta graafiline kasutajaliides. \u00c4kki on kellelegi kasulik? Link GitHubi<\/a><\/noindex>.
