SaltStack实战之配置管理-Jinja2模板

@(学习)[SaltStack]

1. Salt yaml配置文件使用Jinja2模板介绍

jinja2官方网站：
http://jinja.pocoo.org/

1.1 File状态使用template参数

- template: jinja

1.2 模板文件里面变量使用{{ 名称 }}

{{ PORT }}

1.3 变量列表

- defaults:  PORT: 8080

2. 实战应用

添加监听主机和端口变量

vim /srv/salt/devfiles/httpd.conf

Listen {{ HOST }}:{{ PORT }}# {{ MAC }}

配置salt master配置文件、pillar配置文件、lamp.sls添加jinja模板：

[root@salt-master112 dev]# egrep -v '^$|^[#]' /etc/salt/masterstate_top: top.slsfile_roots:  base:    - /srv/salt  dev:    - /srv/salt/dev  test:    - /srv/salt/test  prod:    - /srv/salt/prodpillar_roots:  base:    - /srv/salt/pillar  dev:    - /srv/salt/dev/pillar[root@salt-master112 dev]# cat /srv/salt/pillar/top.sls dev:  'node*.test.com':    - apache[root@salt-master112 dev]# cat /srv/salt/dev/pillar/apache.sls apache:  HOST: {{ grains['fqdn_ip4'][0] }}  PORT: 8080  MAC: {{ salt['network.hw_addr']('eth0') }}[root@salt-master112 dev]# salt '*' saltutil.refresh_pillar node1.test.com:    Truemaster.test.com:    Truenode2.test.com:    True[root@salt-master112 dev]# salt '*' pillar.items            master.test.com:    ----------node1.test.com:    ----------    apache:        ----------        HOST:            10.1.0.109        MAC:            00:50:56:a4:44:7a        PORT:            8080node2.test.com:    ----------    apache:        ----------        HOST:            10.1.0.110        MAC:            00:50:56:a4:44:7a        PORT:            8080[root@salt-master112 dev]# cat /srv/salt/dev/lamp.sls lamp-pkg-install:  pkg.installed:    - names:      - php      - php-fpm      - mysql      - php-mysql      - php-pdoapache-service:  pkg.installed:    - name: httpd  file.managed:    - name: /etc/httpd/conf/httpd.conf    - source:      - salt://files/httpd.conf    - user: root    - group: root    - mode: 644    - template: jinja    - defaults:      HOST: {{ pillar['apache']['HOST'] }}      PORT: {{ pillar['apache']['PORT'] }}      MAC: {{ pillar['apache']['MAC'] }}    - require:      - pkg: apache-service  service.running:    - name: httpd    - enable: True    - reload: True    - watch:      - file: apache-servicemysql-service:  pkg.installed:    - name: mysql-server    - require_in:      - file: mysql-service  file.managed:    - name: /etc/my.cnf    - source:      - salt://files/my.cnf    - user: root    - group: root    - mode: 644    - watch_in:      - service: mysql-service  service.running:    - name: mysqld    - enable: Truephp-fpm-service:  service.running:    - name: php-fpm    - enable: True[root@salt-master112 dev]#
