SaltStack – Using the Mysql Module

Posted 2020-09-20

salt ‘*‘ saltutil.refresh_pillar

官网的例子真的没看懂，英文菜。其实就简单一步。

参考文档

https://docs.saltstack.com/en/latest/ref/modules/all/salt.modules.mysql.html

https://z900collector.wordpress.com/linux/using-the-saltstack-mysql-module/

salt-master主要是找/usr/lib/python2.6/site-packages/salt/modules/test.py

[[email protected] salt]# cat /etc/salt/minion

master: 172.1.1.1

id: cm1

mysql.host: ‘localhost‘

mysql.port: 3306

mysql.user: ‘root‘

mysql.socket: ‘x.sock‘

mysql.pass: ‘xx‘ 

mysql.charset: ‘utf8‘

/etc/init.d/salt-minion restart

‘‘‘

执行顺序,测试命令

state.show_sls执行函数来查看salt state的执行顺序

sudo salt stage-db1 state.show_sls mysql

sudo salt stage-db1 state.apply mysql test=True

sudo salt stage-db1 state.apply mysql

mysql

sudo salt stage-db1 mysql.db_list

‘‘‘

salt ‘*‘ mysql.db_list

1.salt-minion端

mysql连接信息 /etc/salt/minion.d/mysql.conf

mysql.default_file: ‘/etc/mysql/salt.cnf‘

vim /etc/mysql/salt.cnf

mysql.host: ‘localhost‘

mysql.port: 3306

mysql.user: ‘root‘

mysql.socket: ‘x.sock‘

mysql.pass: ‘xx‘ 

mysql.charset: ‘utf8‘

2.vim /srv/pillar/top.sls

base:

  ‘[email protected]:dev and [email protected]:dbserver‘:

    - match: compound

    - dev.mysql

  ‘[email protected]:stage and [email protected]:dbserver‘:

    - match: compound

    - stage.mysql

  ‘[email protected]:prod and [email protected]:dbserver‘:

    - match: compound

    - prod.mysql

3.vim /srv/salt/mysql/init.sls

debconf-utils:

  pkg.installed

mysql_setup:

  debconf.set:

    - name: mysql-server

    - data:

        ‘mysql-server/root_password‘: {‘type‘: ‘password‘, ‘value‘: ‘{{ salt[‘pillar.get‘](‘mysql:root_pw‘, ‘‘) }}‘ }

        ‘mysql-server/root_password_again‘: {‘type‘: ‘password‘, ‘value‘: ‘{{ salt[‘pillar.get‘](‘mysql:root_pw‘, ‘‘) }}‘ }

    - require:

      - pkg: debconf-utils

python-mysqldb:

  pkg.installed

mysql-server:

  pkg.installed:

    - require:

      - debconf: mysql-server

      - pkg: python-mysqldb

mysql:

  service.running:

    - watch:

      - pkg: mysql-server

      - file: /etc/mysql/my.cnf

mysql:

  service.running:

    - watch:

      - pkg: mysql-server

      - file: /etc/mysql/my.cnf

/etc/mysql/my.cnf:

  file.managed:

    - source: salt://mysql/files/etc/mysql/my.cnf.jinja

    - template: jinja

    - user: root

    - group: root

    - mode: 640

    - require:

      - pkg: mysql-server

/etc/salt/minion.d/mysql.conf:

  file.managed:

    - source: salt://mysql/files/etc/salt/minion.d/mysql.conf

    - user: root

    - group: root

    - mode: 640

    - require:

      - service: mysql

/etc/mysql/salt.cnf:

  file.managed:

    - source: salt://mysql/files/etc/mysql/salt.cnf.jinja

    - template: jinja

    - user: root

    - group: root

    - mode: 640

    - require:

      - service: mysql

restart_minion_for_mysql:

  service.running:

    - name: salt-minion

    - watch:

      - file: /etc/salt/minion.d/mysql.conf

上面是digitoean云上的例子。最重要的是/etc/salt/minion.d
