Lumea modern\u0103 a administratorilor de sistem ne-a r\u0103sf\u0103\u021bat cu interfe\u021be web frumoase, astfel c\u0103 nu mai avem nici m\u0103car chef s\u0103 instal\u0103m software care nu are acest \"gui\" (simt c\u0103 acum vor zbura critici de la adep\u021bii r\u00e2ndurilor de comand\u0103), nu-i a\u0219a c\u0103 nu vrei s\u0103 tot intri acolo prin linie de comand\u0103, nu? Ar fi fost perfect dac\u0103 ai putea s\u0103 instalezi software-ul, s\u0103-l configurezi \u0219i s\u0103-l ui\u021bi, dar ce faci c\u00e2nd trebuie s\u0103 intri constant, s\u0103 modifici, \u0219i, desigur, nu exist\u0103 un jurnal al tuturor ac\u021biunilor.

\nAcum mul\u021bi ani, am descoperit un minunat echilibrator numit Haproxy. Totul era fantastic \u0219i frumos. Am ajuns s\u0103 am multe dintre ele \u0219i m-am g\u00e2ndit s\u0103 caut un GUI pentru el, dar cu surprindere am descoperit c\u0103 nu exista. Un software foarte popular, de altfel destul de vechi, dar am trecut la g\u00e2ndul c\u0103 poate nu e mare lucru \u0219i am continuat s\u0103 editez ocazional \u00een viul meu preferat \u0219i s\u0103 am o mul\u021bime de tab-uri deschise cu statisticile tuturor activelor. servere<\/a>. \u00cens\u0103 a venit vremea s\u0103 satisfac \u201edorin\u021bele\u201d oamenilor care au scris software pentru a lucra prin http, \u0219i aici a \u00eenceput partea interesant\u0103\u2026 <\/p>\n

M\u00e2inile au \u00eenceput s\u0103 cheme, ochii s-au aprins \u0219i am pornit la treab\u0103. Mai exact, am \u00eenceput s\u0103 m\u0103 g\u00e2ndesc la ce s\u0103 scriu, am \u00eenceput s\u0103-mi amintesc PHP-ul uitat de mult, dar nu prea aveam chef, \u0219i p\u0103rea c\u0103 nu se potrive\u0219te foarte bine pentru asta. \u00cen final, am ales Python, m-am g\u00e2ndit c\u0103 va fi cu siguran\u021b\u0103 util \u00een viitor \u0219i am \u00eenceput s\u0103 absorb informa\u021bii.<\/p>\n

La \u00eenceput, sarcinile nu erau at\u00e2t de complicate: posibilitatea de a edita configura\u021biile dintr-o interfa\u021b\u0103 web dintr-un singur punct de acces, p\u0103strarea versiunilor anterioare ale configura\u021biilor. Aceast\u0103 func\u021bionalitate, de\u0219i nu foarte mare, a fost realizat\u0103 destul de rapid, dar \u00een mine a \u00eenceput s\u0103 se declan\u0219eze fie lenea de administrator, fie atitudinea bine cunoscut\u0103 a perfec\u021bionismului \u0219i mi s-a p\u0103rut c\u0103 este, desigur, prea pu\u021bin. \u0218i aici au \u00eenceput s\u0103 ap\u0103rea func\u021bii precum: compararea a dou\u0103 configura\u021bii, jurnalizarea tuturor ac\u021biunilor legate de configura\u021bii, API Runtime \u0219i ad\u0103ugarea sec\u021biunilor prin intermediul web-ului.<\/p>\n

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

\u0218i, ca un administrator UNIX de bun\u0103 credin\u021b\u0103 care tr\u0103ie\u0219te din software-ul liber, am decis s\u0103 \u00eemp\u0103rt\u0103\u0219esc cu lumea, poate va fi de folos cuiva? Dar pentru asta trebuia s\u0103 fac totul astfel \u00eenc\u00e2t s\u0103 nu fie necesar s\u0103 m\u0103 scufund \u00een cod, ci s\u0103 intervin maximal \u00een configurare (Acum majoritatea set\u0103rilor s-au mutat \u00een baz\u0103. Din punctul meu de vedere, a devenit mai convenabil de editat \u0219i la actualizare nu vor ap\u0103rea erori din cauza lipsei vreunui parametru \u00een configura\u021bie). <\/p>\n

Dup\u0103 o lun\u0103, am publicat crea\u021bia mea pe Github, f\u0103r\u0103 a avea a\u0219tept\u0103ri prea mari. Dar degeaba, software-ul s-a dovedit pu\u021bin c\u0103utat \u0219i de aici a \u00eenceput partea interesant\u0103... Activitatea de \u201e\u00eembun\u0103t\u0103\u021bire\u201d dureaz\u0103 deja aproape un an. Uneori simt dorin\u021ba de a renun\u021ba, deoarece nevoile mele sunt deja satisf\u0103cute de mult. Dar de ce mi-ar trebui posibilitatea de a desf\u0103\u0219ura un \u201ecluster\u201d cu keepalived \u0219i HAProxy printr-o interfa\u021b\u0103 web, c\u00e2nd \u00eemi ia cel mult c\u00e2teva minute? Se pare c\u0103 oamenii au nevoie de asta, da, \u0219i \u0219i eu sunt interesat, \u0219i am cu ce s\u0103 m\u0103 ocup. De\u0219i, desigur, exist\u0103 \u0219i func\u021bii necesare pentru mine, cum ar fi monitorizarea serverelor backend, dac\u0103 acestea sunt disponibile pentru Haproxy. Avem desigur monitorizare corporativ\u0103, dar acolo sunt oameni care pot r\u0103spunde suficient de \u00eencet, + av\u00e2nd \u00een vedere c\u0103 departamentul meu se ocup\u0103 de dezvoltare \u0219i software-ul apare \u0219i dispare, este destul de greu s\u0103 treci prin birocra\u021bie.<\/p>\n

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

\u00cen general, am decis s\u0103 \u00eemp\u0103rt\u0103\u0219esc, deoarece se pare c\u0103 acesta este singurul GUI gratuit. Poate c\u0103 va fi de folos cuiva? Link c\u0103tre GitHub<\/a><\/noindex>.
