簡介

通過ansible-playbook批量編譯安裝lamp（apache+php及擴充套件）並進行初始化（自動載入php模組，修改mpm、日誌輪儲等），後續我們只需修改站點檔案即可。

ansible-playbook配置思路：
1.通過vars中的main.yml配置變數，主要為原始碼存放目錄及安裝目錄
2.通過tasks中的copy.yml將原始碼檔案傳輸到異地伺服器上原始碼存放目錄
3.通過tasks中的install.yml呼叫模板lamp_install.sh，將lamp安裝到變數中定義的安裝目錄
4.通過tasks中的main.yml呼叫copy模組和install模組
5.通過lamp.yml呼叫劇本（playbook）：lamp_install

playbook的目錄結構

[[email protected] ansible]# cd /etc/ansible/
[[email protected] ansible]# mkdir -p roles/lamp_install/{files,handlers,meta,tasks,templates,vars}

說明：
files：存放需要同步到異地伺服器的原始碼檔案及配置檔案；
handlers：當資源發生變化時需要進行的操作，若沒有此目錄可以不建或為空；
meta：角色定義可留空；
tasks：lamp安裝過程成需要進行的執行的任務；
templates：用於執行lamp安裝的模板檔案，一般為指令碼；
vars：本次安裝定義的變數

具體操作

1.建立lamp角色檔案，用於呼叫lamp_install

[[email protected]  ansible]# vim lamp.yml
- hosts: test
  remote_user: root
  gather_facts: False
  roles:
    - lamp_install

2.建立變數檔案

[root@test ansible]# cd /etc/ansible/roles/lamp_install/vars
[root@test ansible]#vim main.yml
#原始碼存放目錄
source_dir: /home/ap/src/lamp/
#原始碼安裝目錄
install_dir: /home/ap/

3.建立任務檔案

[[email protected] ansible]# cd /etc/ansible/roles/mysql_install/tasks
[[email protected] ansible]# vim copy.yml
#複製php元件至目標伺服器
- name: copy php dir to client
  copy: src=php dest={{source_dir}} owner=root group=root
#複製apache元件至目標伺服器
- name: copy apache dir to client
  copy: src=apache dest={{source_dir}} owner=root group=root
#複製memcached元件至目標伺服器
- name: copy memcached dir to client
  copy: src=memcached dest={{source_dir}} owner=root group=root
#複製模板檔案至目標伺服器
- name: copy lamp script to client
  template: src=lamp_install.sh dest={{source_dir}} owner=root group=root mode=0775
[[email protected] ansible]# vim install.yml
#執行模板檔案進行安裝
- name: install lamp
  shell: bash {{source_dir}}/lamp_install.sh
[[email protected] ansible]# vim main.yml
#引用copy、install模組
- include: copy.yml
- include: install.yml

注意：
a.copy如果複製目錄，需要加上遞迴引數，recurse；
b.copy如果複製目錄，沒有目錄將會在目標伺服器上建立；
c.copy如果複製檔案到目標伺服器的某一個目錄下，需要在dest引數上加上/home/ap/src/lamp/，而不是/home/ap/lamp，否則ansible將會把檔案複製為lamp，而不是放在lamp目錄下。
4.編寫模板指令碼
