實驗目標
使用SaltStack部署apache和php
修改master的配置文件，指定base環境路徑，base環境是必須指定的
[[email protected] base]# grep -9 ^file_roots /etc/salt/master |grep -v ^# file_roots: base: - /srv/salt/base dev: - /srv/salt/dev test: - /srv/salt/test prod: - /srv/salt/prod
創建目錄
[[email protected] base]# mkdir-p /srv/salt/{base,dev,test,prod} [[email protected]-node1 base]# tree /srv/salt/ /srv/salt/ ├── base ├── dev ├── prod └── test
重啟master
[[email protected] base]# systemctl restart salt-master
在base目錄下面創建一個web目錄用於存放web相關的sls文件
[[email protected] base]# mkdir -p web
cd到bash/web目錄裏面創建apache.sls文件
[[email protected] base]# cd web/ [[email protected]-node1 web]# cat apache.sls apache-install: #id 名字自己取 需要形象一點， 一個id下面一個狀態只能出現一次 pkg.installed: #pkg 是狀態模塊，installed 是模塊裏面的方法 - name: httpd #方法裏面的參數 apache-service: service.running: - name: httpd - enable: True #設置開機自動啟動#yaml裏面格式有嚴格的要求，註釋用#號，不能有table，- 兩邊需要空格，縮進用2個空格層級關系後面要加分號
執行狀態模塊部署服務
[[email protected] base]# salt "linux-node2*" state.sls apache linux-node2.example.com: ---------- ID: apache-install Function: pkg.installed Name: httpd Result: True Comment: Package httpd is already installed. Started: 14:58:09.228934 Duration: 633.681 ms Changes: ---------- ID: apache-service Function: service.running Name: httpd Result: True Comment: Service httpd is already enabled, and is running Started: 14:58:09.863302 Duration: 310.567 ms Changes: ---------- httpd: True Summary ------------ Succeeded: 2 (changed=1) Failed: 0 ------------ Total states run: 2
#此時node2 上面已經部署好了apache
高級狀態的使用 需要在master配置文件裏面打開 state_top: top.sls並重啟master
[[email protected] web]# grep -n ^state_top /etc/salt/master
329:state_top: top.sls
[[email protected] web]# systemctl restart salt-master
在bese環境目錄下面添加top.sls
[[email protected] base]# more top.sls base: ‘linux-node2.example.com‘: - web.apache ‘linux-node1.example.com‘: - web.apache [[email protected]-node1 base]# pwd /srv/salt/base
執行高級模塊方法，高級方法到 base下面找top.sls 文件編排告訴每個minion需要幹什麽
一般生產環境用高級狀態多些
[[email protected] base]# salt "*" state.highstate linux-node1.example.com: ---------- ID: apache-install Function: pkg.installed Name: httpd Result: True Comment: Package httpd is already installed. Started: 15:23:08.597951 Duration: 709.521 ms Changes: ---------- ID: apache-service Function: service.running Name: httpd Result: True Comment: Service httpd is already enabled, and is in the desired state Started: 15:23:09.308417 Duration: 233.623 ms Changes: Summary ------------ Succeeded: 2 Failed: 0 ------------ Total states run: 2 linux-node2.example.com: ---------- ID: apache-install Function: pkg.installed Name: httpd Result: True Comment: Package httpd is already installed. Started: 15:23:09.171596 Duration: 721.901 ms Changes: ---------- ID: apache-service Function: service.running Name: httpd Result: True Comment: Service httpd is already enabled, and is in the desired state Started: 15:23:09.894209 Duration: 221.615 ms Changes: Summary ------------ Succeeded: 2 Failed: 0 ------------ Total states run: 2
上面我們使用了2個狀態模塊pkg和service，下面我們使用file文件配置模塊
模塊使用參考文檔
https://www.unixhot.com/docs/saltstack/ref/states/all/salt.states.file.html#module-salt.states.file
在base/web目錄下面添加一個lamp.sls,
一般在添加裏面的內容之前需要在外面找一臺服務器進行測試拿到準確的包信息後再進行配置
[[email protected] web]# cat lamp.sls
lamp-install:
pkg.installed:
- pkgs:
- httpd
- php
- php-pdo
- php-mysql
apache-config:
file.managed:
- name: /etc/httpd/conf/httpd.conf #服務實際使用的文件路徑
- source: salt://web/files/httpd.conf #salt的源文件用於分發到minion上面 路徑是base目錄下面的web 這裏也支持http和ftp方式
- user: root
- group: root
- mode: 644
php-config:
file.managed:
- name: /etc/php.ini
- source: salt://web/files/php.ini
- user: root
- group: root
- mode: 644
lamp-service:
service.running:
- name: httpd
- enable: True
拷貝源文件到base/web目錄下，這個根據自己的實際情況找源文件拷貝過來
[[email protected] web]# cp /etc/httpd/conf/httpd.conf /srv/salt/base/web/files/
[[email protected] web]# cp /etc/php.ini /srv/salt/base/web/files/
