SaltStack的salt-ssh使用及LAMP状态设计部署

1、salt-ssh的使用

官方文档：https://docs.saltstack.com/en/2016.11/topics/ssh/index.html

（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: 192.168.56.11user: rootpasswd: 123123 linux-node2:host: 192.168.56.12user: rootpasswd: 123123（3）使用ssh远程执行 [root@linux-node1 ~]# salt-ssh '*' -r 'uptime' linux-node2:----------retcode:0stderr:stdout:root@192.168.56.12's password: 14:07:19 up 14 days, 8:41, 2 users, load average: 0.04, 0.08, 0.07 linux-node1:----------retcode:0stderr:stdout:root@192.168.56.11's password: 14:07:20 up 23 days, 8:13, 2 users, load average: 2.86, 0.81, 0.34

2、配置管理

（1）什么是状态？

所谓的状态就是希望系统运行某些命令之后的结果。描述状态使用YAML格式的文件。SLS：salt state
举例安装apache，如下：

[root@linux-node1 ~]# vim /srv/salt/base/web/apache.sls apache:pkg.installed:- name: httpdservice.running:- name: httpdfile.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 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: httpdapache-service:service.running:- name: httpdapache-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name) /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

（2） LAMP的状态设计与实现部署

1、设计分析

名称软件包配置文件服务

使用模块	pkg	file	service
LAMP	httpd、php、mariadb、mariadb-server、php-mysql、php-pdo、php-cli	/etc/httpd/conf/httpd.conf、/etc/php.ini	httpd、mysqld

2、Aapche的状态配置

[root@linux-node1 prod]# pwd /srv/salt/prod [root@linux-node1 prod]# mkdir apache php mysql [root@linux-node1 prod]# tree . ├── apache ├── mysql └── php3 directories, 0 files[root@linux-node1 prod]# cd apache/ [root@linux-node1 apache]# vim apache.sls #编写apache的状态模块 apache-install:pkg.installed:- name: httpdapache-config:file.managed:- name: /etc/httpd/conf/httpd.conf- source: salt://apache/files/httpd.conf #salt://代表着环境的根路径- user: root- group: root- mode: 644apache-service:service.running:- name: httpd- enable: True [root@linux-node1 apache]# mkdir files #创建source目录 [root@linux-node1 apache]# cd files/ [root@linux-node1 files]# cp /etc/httpd/conf/httpd.conf . [root@linux-node1 apache]# tree . ├── apache.sls └── files└── httpd.conf1 directory, 2 files [root@linux-node1 apache]# salt 'linux-node1' state.sls apache.apache saltenv=prod

3、php的状态配置

[root@linux-node1 prod]# cd php [root@linux-node1 php]# mkdir files [root@linux-node1 php]# vim init.sls php-install:pkg.installed:- pkgs:- php- php-pdo- php-mysqlphp-config:file.managed:- name: /etc/php.ini- source: salt://php/files/php.ini- user: root- group: root- mode: 644 [root@linux-node1 php]# cp /etc/php.ini files/ [root@linux-node1 php]# tree . ├── files │ └── php.ini └── init.sls1 directory, 2 files

4、mysql的状态配置

[root@linux-node1 prod]# cd mysql/ [root@linux-node1 mysql]# vim init.sls mysql-install:pkg.installed:- pkgs:- mariadb- mariadb-servermysql-config:file.managed:- name: /etc/my.cnf- source: salt://mysql/files/my.cnf- user: root- gourp: root- mode: 644mysql-service:service.running:- name: mariadb-server- enable: True [root@linux-node1 mysql]# mkdir files [root@linux-node1 mysql]# cp /etc/my.cnf files/ [root@linux-node1 prod]# tree . ├── apache │ ├── files │ │ └── httpd.conf │ └── init.sls ├── mysql │ ├── files │ │ └── my.cnf │ └── init.sls └── php├── files│ └── php.ini└── init.sls [root@linux-node1 prod]# salt -S '192.168.56.11' state.sls php.init saltenv=prod linux-node1.example.com: ----------ID: php-installFunction: pkg.installedResult: TrueComment: The following packages were installed/updated: php-mysqlThe following packages were already installed: php-pdo, phpStarted: 10:30:14.780998Duration: 118711.436 msChanges: ----------php-mysql:----------new:5.4.16-43.el7_4old: ----------ID: php-configFunction: file.managedName: /etc/php.iniResult: TrueComment: File /etc/php.ini is in the correct stateStarted: 10:32:13.556562Duration: 51.913 msChanges: Summary for linux-node1.example.com ------------ Succeeded: 2 (changed=1) Failed: 0 ------------ Total states run: 2 Total run time: 118.763 s

5、写入top file，执行高级状态

[root@linux-node1 base]# pwd /srv/salt/base [root@linux-node1 base]# vim top.sls prod:'linux-node1.example.com':- apache.init- php.init- mysql.init [root@linux-node1 base]# salt 'linux-node1*' state.highstate linux-node1.example.com: ----------ID: apache-installFunction: pkg.installedName: httpdResult: TrueComment: All specified packages are already installedStarted: 10:39:04.214911Duration: 762.144 msChanges: ----------ID: apache-configFunction: file.managedName: /etc/httpd/conf/httpd.confResult: TrueComment: File /etc/httpd/conf/httpd.conf is in the correct stateStarted: 10:39:04.979376Duration: 13.105 msChanges: ----------ID: apache-serviceFunction: service.runningName: httpdResult: TrueComment: The service httpd is already runningStarted: 10:39:04.992962Duration: 36.109 msChanges: ----------ID: php-installFunction: pkg.installedResult: TrueComment: All specified packages are already installedStarted: 10:39:05.029241Duration: 0.65 msChanges: ----------ID: php-configFunction: file.managedName: /etc/php.iniResult: TrueComment: File /etc/php.ini is in the correct stateStarted: 10:39:05.029987Duration: 10.642 msChanges: ----------ID: mysql-installFunction: pkg.installedResult: TrueComment: All specified packages are already installedStarted: 10:39:05.040793Duration: 0.422 msChanges: ----------ID: mysql-configFunction: file.managedName: /etc/my.cnfResult: TrueComment: File /etc/my.cnf is in the correct stateStarted: 10:39:05.041301Duration: 7.869 msChanges: ----------ID: mysql-serviceFunction: service.runningName: mariadbResult: TrueComment: The service mariadb is already runningStarted: 10:39:05.049284Duration: 28.054 msChanges: Summary for linux-node1.example.com ------------ Succeeded: 8 Failed: 0 ------------ Total states run: 8 Total run time: 858.995 ms 本文转自 IT_外卖小哥  51CTO博客，原文链接:http://blog.51cto.com/jinlong/2062769 SaltStackSaltStack
