Uvod<\/b>: po naklju\u010dju sem iz sveta akademske znanosti (medicine) pri\u0161la v svet informacijske tehnologije, kjer moram uporabljati svoje znanje o metodologiji postavljanja eksperimentov in strategijah analize eksperimentalnih podatkov, vendar pa uporabljam nov sklop tehnologij, ki je nov zame. Med u\u010denjem teh tehnologij se sre\u010dujem s \u0161tevilnimi izzivi, ki jih zaenkrat, hvala bogu, uspe\u0161no premagujem. Morda bo ta objava koristna tistim, ki prav tako \u0161ele za\u010denjajo delo na projektih Apache. <\/p>\n

Torej, k bistvu<\/b>. Navdihnjena \u010dlanek <\/a><\/noindex> z Yurovimi Emeljanovimi mo\u017enostmi Apache Airflow na podro\u010dju avtomatizacije analiti\u010dnih postopkov, sem si \u017eelela za\u010deti uporabljati ponujeni nabor knji\u017enic v svojem delu. Tistim, ki \u0161e sploh niso seznanjeni z Apache Airflow, je lahko zanimiv kratek pregled \u010dlanek <\/a><\/noindex> na spletni strani Nacionalne knji\u017enice N. E. Baumana. <\/p>\n

Ker obi\u010dajna navodila za zagon Airflow, kot se zdi, niso uporabna v okolju Windows, in bi bilo v mojem primeru docker <\/a><\/noindex> prekomerno, sem za\u010dela iskati druge re\u0161itve. Na sre\u010do zame, nisem bila prva na tej poti, zato sem uspela najti odli\u010den video vodi\u010d<\/a><\/noindex> za namestitev Apache Airflow v Windows 10 brez uporabe dockerja. Toda, kot se pogosto zgodi, so se pri izvajanju priporo\u010deni korakov pojavili izzivi, in verjamem, da ne samo pri meni. Zato bi \u017eelela deliti svoje izku\u0161nje z namestitvijo Apache Airflow, morda bo to nekomu prihranilo malo \u010dasa.
\n<\/a><\/noindex>
\nPoglejmo korake navodila (spoiler \u2014 pri 5. koraku je vse \u0161lo odli\u010dno):<\/p>\n

1. Namestitev Windows podsystema za Linux za naknadno namestitev Linux distribucij<\/b><\/p>\n

To je manj\u0161i problem, kot pravijo: <\/p>\n

Nadzorna plo\u0161\u010da \u2192 Programi \u2192 Programi in funkcije \u2192 Aktivacija in deaktivacija funkcij sistema Windows \u2192 Windows podsystema za Linux<\/p>\n

2. Namestitev distribucije Linux po izbiri<\/b><\/p>\n

Uporabila sem aplikacijo Ubuntu<\/a><\/noindex>.<\/p>\n

3. Namestitev in posodobitev pip <\/b><\/p>\n

sudo apt-get install software-properties-common\nsudo apt-add-repository universe\nsudo apt-get update\nsudo apt-get install python-pip<\/code><\/pre>\n
\n4. Namestitev Apache Airflow<\/b><\/p>\n
export SLUGIFY_USES_TEXT_UNIDECODE=yes\npip install apache-airflow<\/code><\/pre>\n
\n5. Inicializacija baze podatkov<\/b><\/p>\n
In prav tukaj so se za\u010deli moji majhni izzivi. Navodila predpisujejo, da vnesem ukaz airflow initdb<\/code> in preidem na naslednji korak. Vendar sem nenehno dobivala odgovor airflow: command not found<\/code>. Logi\u010dno je pretpostaviti da su se pojavile pote\u0161ko\u0107e tokom instalacije Apache Airflow-a i da jednostavno nema potrebnih datoteka. Uveriv\u0161i se da je sve gde treba da bude, odlu\u010dila sam da probam da navedem pun put do datoteke airflow (trebalo bi da izgleda ovako: Pun\/put\/do\/datoteke\/airflow initdb<\/code>). Ali \u010duda nije bilo i odgovor je bio isti airflow: command not found<\/code>. Poku\u0161ala sam da koristim relativni put do datoteke (.\/.local\/bin\/airflow initdb<\/code>), \u0161to je dovelo do nove gre\u0161ke ModuleNotFoundError: Nema modula pod nazivom 'json'<\/code>, koju se mo\u017ee prevazi\u0107i a\u017euriranjem biblioteke werkzeug<\/i> (u mom slu\u010daju na verziju 0.15.4):<\/p>\n
pip install werkzeug==0.15.4<\/code><\/pre>\n
\nO werkzeug-u se mo\u017ee pro\u010ditati vi\u0161e ovde<\/a><\/noindex>. <\/p>\n
Nakon ove jednostavne manipulacije komanda .\/.local\/bin\/airflow initdb<\/code> je uspe\u0161no izvr\u0161ena. <\/p>\n
6. Pokretanje Airflow servera<\/b><\/p>\n
Time problemi sa pristupanjem airflow-u jo\u0161 nisu zavr\u0161eni. Pokretanje komande .\/.local\/bin\/airflow webserver -p 8080<\/code> dovelo je do gre\u0161ke Nema takve datoteke ili direktorijuma<\/code>. Verovatno bi iskusan korisnik Ubuntua odmah poku\u0161ao da prevazi\u0111e takve pote\u0161ko\u0107e sa pristupanjem datoteci koriste\u0107i komandu export PATH=$PATH:~\/.local\/bin\/<\/code> (tj. dodaju\u0107i postoje\u0107em putu za pretragu izvr\u0161nih datoteka, koji defini\u0161e promenljiva PATH, direktorijum \/.local\/bin\/), ali ova objava je namenjena onima koji prete\u017eno rade na Windows-u i mo\u017eda ne smatraju to re\u0161enje o\u010diglednim. <\/p>\n
Nakon navedene manipulacije komanda .\/.local\/bin\/airflow webserver -p 8080<\/code> je uspe\u0161no izvr\u0161ena.<\/p>\n
7. URL: localhost<\/noindex>:8080\/<\/b><\/p>\n
Ako je sve pro\u0161lo dobro na prethodnim koracima, spremni ste da osvojite analiti\u010dke vrhove.<\/p>\n
Nadam se da \u0107e gore opisano iskustvo instalacije Apache Airflow-a na Windows 10 biti korisno po\u010detnicima i ubrzati njihovo uklju\u010divanje u svet savremenih analiti\u010dkih alata. <\/p>\n
Slede\u0107i put \u017eelim da nastavim temu i pri\u010dam o iskustvu kori\u0161\u0107enja Apache Airflow-a u analizi pona\u0161anja korisnika mobilnih aplikacija.
