saltstack常用模組

wadeson發表於2017-10-13

介紹一些常用的saltstack模組，更多模組參考官方網站

1、跟安裝包相關的模組：salt.states.pkg

salt.states.pkg.downloaded(name, version=None, pkgs=None, fromrepo=None, ignore_epoch=None, **kwargs)

 

當同時使用了name，pkgs那麼name將會被忽略
 
salt.states.pkg.installed(name, version=None, refresh=None, fromrepo=None, skip_verify=False, skip_suggestions=False, pkgs=None, sources=None, allow_updates=False, pkg_verify=False, normalize=True, ignore_epoch=False, reinstall=False, update_holds=False, **kwargs)

 

salt.states.pkg.removed(name, version=None, pkgs=None, normalize=True, ignore_epoch=False, **kwargs)
removed解除安裝某包

 

2、遠端執行命令的模組

salt.states.cmd.run(name, onlyif=None, unless=None, creates=None, cwd=None, runas=None, shell=None, env=None, stateful=False, umask=None, output_loglevel='debug', quiet=False, timeout=None, ignore_timeout=False, use_vt=False, **kwargs)

 　　name：The command to execute, remember that the command will execute with the path and permissions of the salt-minion.

　　cwd：The current working directory to execute the command in, defaults to /root

　　unless：當執行的命令為false時，那麼才執行name中的命令

　　require：執行name中命令的依賴關係：
　　pkg：必須安裝了python包
　　file：該file檔案路徑下有這個py檔案
3、檔案管理操作方面的模組
salt.states.file.managed(name, source=None, source_hash='`, source_hash_name=None, user=None, group=None, mode=None, template=None, makedirs=False, dir_mode=None, context=None, replace=True, defaults=None, backup='`, show_changes=True, create=True, contents=None, tmp_ext='`, contents_pillar=None, contents_grains=None, contents_newline=True, contents_delimiter=':', encoding=None, encoding_errors='strict', allow_empty=True, follow_symlinks=True, check_cmd=None, skip_verify=False, win_owner=None, win_perms=None, win_deny_perms=None, win_inheritance=True, **kwargs)

 

file.managed:檔案管理，多用於複製，如果沒有就建立該檔案

salt.states.file.append(name, text=None, makedirs=False, source=None, source_hash=None, template='jinja', sources=None, source_hashes=None, defaults=None, context=None, ignore_whitespace=True) 
append-memcache-php:
  file.append:
    - name: /usr/local/php/etc/php.ini
    - text:
      - extension=memcache.so
  cmd.run:
    - name: /etc/init.d/php-fpm restart

 file.append：向某檔案中新增內容text=內容，name為需要新增的檔案

salt.states.file.directory(name, user=None, group=None, recurse=None, max_depth=None, dir_mode=None, file_mode=None, makedirs=False, clean=False, require=None, exclude_pat=None, follow_symlinks=False, force=False, backupname=None, allow_symlink=True, children_only=False, win_owner=None, win_perms=None, win_deny_perms=None, win_inheritance=True, **kwargs)

 file.directory：建立一個檔案目錄

/etc/keepalived:
  file.directory:
    - user: root
    - group: root
    - mode: 755

 4、跟系統服務相關：state.service

salt.states.service.running(name, enable=None, sig=None, init_delay=None, no_block=False, unmask=False, unmask_runtime=False, **kwargs)

 service.running：開啟系統某服務enable為新增到自啟動，name表示該啟動的服務名稱

  service.running:
    - name: nginx
    - enable: True
    - reload: True
    - require: 
      - file: /etc/init.d/nginx
      - cmd: nginx-init
    - watch:
      - file: /usr/local/nginx/conf/nginx.conf

 5、跟系統核心相關的設定：

salt.states.sysctl.present(name, value, config=None) Ensurethatthenamedsysctlvalueissetinmemoryandpersistedtothenamedconfigurationfile. Thedefault sysctl configuration file is /etc/sysctl.conf name The name of the sysctl value to edit value The sysctl value to apply config Thelocationofthesysctlconfigurationfile. Ifnotspecified,theproperlocationwillbedetectedbased on platform.

 sysctl.present:修改系統核心引數

[root@node1 init]# cat sysctl.sls 
vm.swappiness:
  sysctl.present:
    - value: 0

net.ipv4.ip_local_port_range:
  sysctl.present:
    - value: 10000 61000

fs.file-max:
  sysctl.present:
    - value: 186981

 6、建立使用者user和group用到的模組

www-user-group:
  group.present:
    - name: www
    - gid: 1000

  user.present:
    - name: www
    - fullname: www
    - shell: /sbin/nologin
    - uid: 1000
    - gid: 1000

 7、狀態配置中require、unless詳解：

[root@node1 base]# cat if_unless.sls 
getshell:
  file.managed:
    - name: /tmp/echo.sh
    - source: salt://init/files/echo.sh
  cmd.run:
    - name: /bin/bash /tmp/echo.sh
    - unless: test -f /tmp/if_unless.sh
    - require:
      - file: /tmp/echo.sh

 詳解：

require：require要求下面的file必須事先經過了file.managed進行了設定，才能使用作為依賴條件
unless：測試tmp下面是否有if_unless.sh這個檔案，如果測試成功有那麼不會再執行，如果測試命令返回的code不是0那麼才會執行
unless：一行表示，如果該檔案存在，就不需要再執行name中的命令了（包如果安裝了就需要再安裝）
 
8、使用template: jinja來定義變數
zabbix-agent-service:
  file.managed:
    - name: /etc/zabbix/zabbix_agentd.conf
    - source: salt://init/files/zabbix_agentd.conf
    - template: jinja
    - defaults:
      Server: {{ pillar['zabbix-agent']['Zabbix_Server'] }}

 在該salt://init/files/zabbix_agentd.conf配置檔案中將Server={{ Server }}引用上面定義的變數即可

或者使用grains和pillar使用變數：

keepalived-service:
  file.managed:
    - name: /etc/keepalived/keepalived.conf
    - source: salt://cluster/files/haproxy-outside-keepalived.conf
    - user: root
    - group: root
    - mode: 644
    - template: jinja
    {% if grains['fqdn'] == 'node1' %}
    - ROUTEID: haproxy_node1
    - STATEID: MASTER
    - PRIORITYID: 150
    {% elif grains['fqdn'] == 'node2' %}
    - ROUTEID: haproxy_node2
    - STATEID: BACKUP
    - PRIORITYID: 100
    {% endif %}
