saltstack常用模块

介绍一些常用的saltstack模块，更多模块参考官方网站

1、跟安装包相关的模块：salt.states.pkg

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

当同时使用了name，pkgs那么name将会被忽略

 

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卸载某包

2、远程执行命令的模块

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：当执行的命令为false时，那么才执行name中的命令

　　require：执行name中命令的依赖关系：

　　pkg：必须安装了python包

　　file：该file文件路径下有这个py文件

3、文件管理操作方面的模块

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:文件管理，多用于复制，如果没有就创建该文件

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：向某文件中添加内容text=内容，name为需要添加的文件

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：创建一个文件目录

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

4、跟系统服务相关：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：开启系统某服务enable为添加到自启动，name表示该启动的服务名称

  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、跟系统内核相关的设置：

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:修改系统内核参数

[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、创建用户user和group用到的模块

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

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

7、状态配置中require、unless详解：

[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

详解：

require：require要求下面的file必须事先经过了file.managed进行了设置，才能使用作为依赖条件

unless：测试tmp下面是否有if_unless.sh这个文件，如果测试成功有那么不会再执行，如果测试命令返回的code不是0那么才会执行

unless：一行表示，如果该文件存在，就不需要再执行name中的命令了（包如果安装了就需要再安装）

 

8、使用template: jinja来定义变量

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'] }}

在该salt://init/files/zabbix_agentd.conf配置文件中将Server={{ Server }}引用上面定义的变量即可

或者使用grains和pillar使用变量：

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 %}
