一.include的引用
需求场景:用于含有多个SLS的状态,使用include可以进行多个状态的组合,将安装apache,php,mysql集合在一个sls中
[root@7mini-node1 prod]# pwd/srv/salt/prod[root@7mini-node1 prod]# vim lamp.slsinclude: - apache.init - php.init - mysql.init[root@7mini-node1 prod]# vim ../base/top.sls prod: '7mini-node1': - lamp[root@7mini-node1 prod]# salt "7mini-node1" state.highstate #执行无报错为正确
二.extend的使用
需求场景:软件包安装的时候,需求假设:只在node1上按装php-mbstring包,其他的机器不安装。单独在组合的sls中添加,不需要可以删掉
[root@7mini-node1 prod]# pwd/srv/salt/prod[root@linux-node1 prod]# vim lamp.sls include: - apache.init - php.init - mysql.initextend: php-install: pkg.installed: - name: php-mbstring[root@linux-node1 prod]# salt "7mini-node1" state.highstate
三、require和require_in的使用
require:我依赖谁require_in:我被谁依赖需求场景:如果安装不成功或者配置httpd不成功,不启动httpd
(1)require使用[root@7mini-node1 apache]# pwd/srv/salt/prod/apache[root@7mini-node1 apache]# systemctl stop httpd[root@7mini-node1 apache]# vim init_require.sls apache-install: pkg.installed: - name: httpdapache-config: file.managed: - name: /etc/httpd/conf/httpd.conf - source: salt://apache/files/httpd1.conf----->将此处的文件改错,模拟配置错误 - user: root - group: root - mode: 644apache-service: service.running: - name: httpd - enable: True - require:---------------------------->使用require,表示依赖 - pkg: apache-install--------------->依赖的状态模块为pkg模块,id为apache-install - file: apache-config--------------->依赖的状态模块为file模块,id为apache-config[root@7mini-node1 apache]# salt "7nini-noed1" state.highstate #执行模块提示会有报错,此时httpd不会正常启动
(2)require_in使用 #与require是相同的只是表达方式的不同[root@7mini-node1 apache]# vim init_require_in.sls apache-install: pkg.installed: - name: httpd - require_in:------------------>被依赖 - service: apache-service---->被依赖的模块是service,id为apache-serviceapache-config: file.managed: - name: /etc/httpd/conf/httpd.conf - source: salt://apache/files/httpd.conf - user: root - group: root - mode: 644 - require_in: - service: apache-serviceapache-service: service.running: - name: httpd - enable: True解释说明:require和require_in都能实现依赖的功能,主动和被动的关系不同
四、watch和watch_in的使用
需求场景:监控配置文件变动,重启服务或重载服务
设置重启
[root@7mini-node1 apache]# pwd/srv/salt/prod/apache[root@7mini-node1 apache]# vim init_watch.sls apache-install: pkg.installed: - name: httpdapache-config: file.managed: - name: /etc/httpd/conf/httpd.conf - source: salt://apache/files/httpd.conf - user: root - group: root - mode: 644apache-service: service.running: - name: httpd - enable: True - watch:---------------------->使用watch - file: apache-config------->监控的模块为file,id为apache-config[root@7mini-node1 apache]# vim files/httpd.conf #随意修改配置文件[root@7mini-node1 apache]# salt "7mini-node1" state.highstate
设置重载
[root@7mini-node1 apache]# vim init_watch.sls apache-install: pkg.installed: - name: httpdapache-config: file.managed: - name: /etc/httpd/conf/httpd.conf - source: salt://apache/files/httpd.conf - user: root - group: root - mode: 644apache-service: service.running: - name: httpd - enable: True - reload: True----------------------------------->增加参数重载 - watch: - file: apache-config[root@7mini-node1 apache]# salt -S "192.168.56.11" state.highstate
五、unless:状态间的条件判断
需求场景:给apache的admin目录进行加密登陆查看 #如果某文件存在将不执行
(1)修改配置文件,添加认证功能[root@7mini-node1 apache]# vim files/httpd.confAllowOverride All Order allow,deny Allow from all AuthType Basic AuthName "haha" AuthUserFile /etc/httpd/conf/htpasswd_file Require user admin (2)修改状态文件init.sls[root@7mini-node1 apache]# vim init.sls apache-install: pkg.installed: - name: httpdapache-config: file.managed: - name: /etc/httpd/conf/httpd.conf - source: salt://apache/files/httpd.conf - user: root - group: root - mode: 644apache-auth: pkg.installed: - name: httpd-tools cmd.run:------>使用cmd模块的run方法 - name: htpasswd -bc /etc/httpd/conf/htpasswd_file admin admin---->生成密码文件 - unless: test -f /etc/httpd/conf/htpasswd_file---->unless判断条件,test -f判断为假则执行。即htpasswd文件如果不存在就执行生成密码apache-service: service.running: - name: httpd - enable: True - reload: True - watch: - file: apache-config[root@7mini-node1 apache]# salt "7mini-node1" state.highstate
