SaltStack的salt-ssh使用及LAMP状态设计部署（五）

（1）安装salt-ssh
[root@linux-node1 ~]# yum install -y salt-ssh

（2）配置salt-ssh
[root@linux-node1 ~]# vim /etc/salt/roster 
linux-node1:
  host: 10.0.0.11
  user: root
  passwd: qwe123
linux-node2:
  host: 10.0.0.12
  user: root
  passwd: qwe123

（3）使用ssh远程执行
[root@7mini-node1 ~]# salt-ssh ‘*‘ -r ‘uptime‘
7mini-node2:
    ----------
    retcode:
        0
    stderr:
    stdout:
        root@10.0.0.12‘s password: 
         14:07:19 up 14 days,  8:41,  2 users,  load average: 0.04, 0.08, 0.07
7mini-node1:
    ----------
    retcode:
        0
    stderr:
    stdout:
        root@10.0.0.11‘s password: 
         14:07:20 up 23 days,  8:13,  2 users,  load average: 2.86, 0.81, 0.34

[root@7mini-node1 ~]# vim /srv/salt/base/web/apache.sls 
apache:
  pkg.installed:
    - name: httpd
  service.running:
    - name: httpd
  file.managed:
    - name: /etc/httpd/conf/httpd.conf
    - source: salt://apache/files/httpd.conf
    - user: root
    - group: root
    - mode: 644

解释说明：
apache：id声明，在所有环境（base、prod）下全局唯一
pkg：状态模块
.：引用关系
installed:模块中的方法
:：代表层级关系
name:可以理解为参数，后面跟的是参数值，id就是name
file.managed:文件管理模块，必须要有source指定文件的来源路径
source：文件的来源路径，salt://代表着环境的根路径，这的根路径为：/srv/salt/base/
user、group、mode：分别指定文件的所属者，所属组和权限

以上的文件还可以使用分id的写法：
apache-install:
  pkg.installed:
    - name: httpd

apache-service:
  service.running:
    - name: httpd

apache-config:
  file.managed:
    - name: /etc/httpd/conf/httpd.conf
    - source: salt://apache/files/httpd.conf
    - user: root
    - group: root
    - mode: 644

存在指定多个配置文件，还可以使用一下写法：(不适用name作为参数传递时，id就是最上面的参数)
/etc/httpd/conf/httpd.conf:
  file.managed:
    - source: salt://apache/files/httpd.conf
    - user: root
    - group: root
    - mode: 644
/etc/httpd/conf/php.conf:
  file.managed:
    - source: salt://apache/files/php.conf
    - user: root
    - group: root
    - mode: 644
