SaltStack实战之配置管理-LAMP自动化部署

1. 部署思路

2. 编写lamp.sls

1. 部署思路

将lamp分成3部分：软件包、配置文件、服务；

确认安装的软件包名、配置文件路径、服务名等；

按以上信息编写yaml文件；

2. 编写lamp.sls

[root@salt-master112 salt]# pwd
/srv/salt
[root@salt-master112 salt]# ls
dev init prod test top.sls
[root@salt-master112 salt]# cat dev/lamp.sls 
lamp-pkg-install:
 pkg.installed:
- names:
 - httpd
 - php
 - php-fpm
 - mysql
 - mysql-server
 - php-mysql
 - php-pdo

apache-service:
 file.managed:
- name: /etc/httpd/conf/httpd.conf
- source:
 - salt://dev/files/httpd.conf
- user: root
- group: root
- mode: 644
 service.running:
- name: httpd
- enable: True

mysql-service:
 file.managed:
- name: /etc/my.cnf
- source:
 - salt://dev/files/my.cnf
- user: root
- group: root
- mode: 644
 service.running:
- name: mysqld
- enable: True

php-fpm-service:
 service.running:
- name: php-fpm
- enable: True
[root@salt-master112 salt]# cat top.sls 
base:
 '*':
- init.dns

dev:
 'node*.test.com':
 - lamp
[root@salt-master112 salt]# ls dev/
files lamp.sls
[root@salt-master112 salt]# ls dev/files/
httpd.conf my.cnf
[root@salt-master112 salt]# 

执行salt '*' state.highstate查看结果：

 [root@salt-master112 salt]# salt-key -L

master.test.com
node1.test.com
node2.test.com
Denied Keys:
Unaccepted Keys:

上面结果中有报错
Unable to manage file: none of the specified sources were found

需要修改路径，把dev去掉。因为在top.sls配置文件中，lamp是定义在dev下面的，因此salt://应该是从dev目录下为起始的。

-salt://files/httpd.conf
