Ana m agba gị ume ka ị gụọ akụkụ 1 na akụkụ 2 tupu ịga n'ihu iji jide n'aka na ị maara nke ọma echiche ndị metụtara ike.

Nzọụkwụ 1: Ewebata Ọrụ Ndị Kwesịrị Ekwesị

Ka ị na-amalite ịgbakwụnye ọtụtụ ọrụ na egwuregwu, akwụkwọ egwuregwu gị nwere ike na-esiwanye ike ijikwa ya. N'ihi nke ahụ, ụzọ akwadoro n'ọnọdụ ndị ahụ (n'ezie, n'ọnọdụ niile) bụ iji usoro ndekọ aha nwere ntuziaka maka otu ọrụ ọ bụla na faịlụ dị iche iche.

Ụzọ a na-enye anyị ohere iji faịlụ nhazi ndị a na-arụ ọrụ dị iche iche na-aga n'ihu n'okporo ụzọ. Nke ọ bụla n'ime faịlụ ndị a na-akọwapụta ihe a na-akpọ na gburugburu ebe obibi nwere ike ịbụ ọrụ.

N'ọnọdụ anyị, anyị ga-emepụta ọrụ abụọ. Otu n'ime ha (nke a na-akpọ wp-dependencies) ga-eji wụnye ndabere WordPress (PHP na MariaDB - ọ dịghị mkpa ịwụnye Apache dị ka etinyere ya).

Ọrụ ọzọ (nke aha ya bụ wp-install-config) ga-agụnye ọrụ niile dị mkpa metụtara ntinye na nhazi nke WordPress.

Nzọụkwụ 2: Ịmepụta Ọrụ Ndị Kwesịrị Ekwesị

Ansible na-abịa na ngwa a na-akpọ ansible-galaxy nke ga-enyere anyị aka ịmepụta ndekọ aha maka ọrụ anyị. Anyị ga-eme nke a na /etc/ansible/playbooks (nke anyị kere na Nkebi 2) mana na tiori ị nwere ike ịtọ ya na ndekọ ọzọ ma ọ bụrụ na ịchọrọ.

Na onyonyo a dị n'elu, anyị nwere ike ịhụ na galaxy nwere ike mepụta akwụkwọ ndekọ aha abụọ nwere otu aha dị ka ọrụ anyị, yana subdirectories ndị ọzọ (ndabara, faịlụ, njikwa, meta, ọrụ, ndebiri, na vars) yana faịlụ README.md n'ime nke ọ bụla. ha.

Na mgbakwunye, e mepụtara faịlụ YAML aha ya bụ main.yml n'ime akwụkwọ ndekọ aha niile edepụtara na mbụ, ewezuga faịlụ na ndebiri.
