e ile ea e-ba e 'ngoe ea tse ratoang ka ho fetisisa ... Kamora ka 2015 palo e feta likete 'me Ansible mohlomong e ile ea fetoha mokhoa o sebelisoang ka ho fetisisa oa ho tsamaisa le oa ho bina. Mefuta e mengata ea likopo tsa eona e khahla haholo.
Ansible e sebetsa ka likhokahano tsa SSH ho baamoheli ba hole. E bula lenaneo la SSH, e kena, e kopitsa khoutu ea Python holim'a marang-rang ebe e e ngolla faeleng e arohaneng ea nakoana. Kamora moo, e tsamaisa faele ena mochining o hole. Tatelano ena kaofela ea ts'ebetso e telele ebile e ea tena, ka hona ho na le mekhoa e fapaneng ea ho e ntlafatsa.
E 'ngoe ea litsela tsena ke e u lumellang hore u sebelise lenaneo le le leng la SSH ho phethahatsa litaelo, ho e-na le ho bula lenaneo le lecha nako le nako, le ka re bolokelang nako e ngata. (Hopola feela ho tima requiretty ho beha sudo ho hau /etc/sudoers faele mochining o hole)
Mokhoa o mocha oa ho overclock Ansible ke laebrari ea python e bitsoang . Haeba mang kapa mang a e-s'o utloe ka eona, ke tla hlalosa ka bokhutšoanyane ts'ebetso ea eona. E lumella ts'ebetso e potlakileng ea khoutu ea python mochining o hole, 'me Ansible ke mohlala o le mong feela oa ts'ebeliso. Mitogen e sebelisa phala ea UNIX mochining o hole mme e fetisetsa khoutu ea python e hatelletsoeng ka zlib ebe e serialized ka pickle. Sena se thusa ho e qeta kapele le ho boloka sephethephethe. Haeba u thahasella tlhaloso e qaqileng haholoanyane, ho molemo ho bala ka eona leqepheng . Empa kajeno re tla shebana feela le hore na laebrari e sebetsa joang le Ansible.
Mitogen maemong a itseng e ka potlakisa khoutu ea hau ea Ansible makhetlo a 'maloa mme ea fokotsa haholo tšebeliso ea sephethephethe. Ha re hlahlobeng linyeoe tsa tšebeliso tse tsebahalang haholo 'me re bone hore na li re thusa hakae.
Ke sebelisa Ansible haholo bakeng sa: ho theha lifaele tsa tlhophiso mochining o hole, ho kenya liphutheloana, ho kopitsa lifaele ho ea le ho tsoa mochining o hole. Mohlomong u na le mehlala e meng - ngola litlhalosong.
A re tsamaee!
Tlhophiso ea Mitogen bakeng sa Ansible e bonolo haholo:
Kenya laeborari ea Mitogen:
pip install mitogenHona joale ho na le mekhoa e 'meli e tšoanang - e ka ba ho lokisa likhetho faeleng ea tlhophiso ea ansible.cfg, kapa beha maemo a hlokahalang a tikoloho.
