009（1）-saltstack之salt-ssh的使用及配置管理LAMP状态的实现
1 salt-ssh的使用
1. 安装salt-ssh
[root@slave1 .ssh]# yum install -y salt-ssh
2. 配置salt-ssh
# Sample salt-ssh config file
#web1:
# host: 192.168.42.1 # The IP addr or DNS hostname
# user: fred # Remote executions will be executed as user fred
# passwd: foobarbaz # The password to use for login, if omitted, keys are used
# sudo: True # Whether to sudo to root, not enabled by default
#web2:
# host: 192.168.42.2
slave1:
host: 10.0.0.211
user: root
passwd: shang185434
slave2:
host: 10.0.0.212
user: root
passwd: shang185434
3.使用salt-ssh远程执行
#第一次远程执行需要交互，加上”-i“ 参数可以免交互
[root@slave1 ~]# salt-ssh '*' test.ping
slave2:
----------
retcode:
stderr:
stdout:
The host key needs to be accepted, to auto accept run salt-ssh with the -i flag:
The authenticity of host '10.0.0.212 (10.0.0.212)' can't be established.
ECDSA key fingerprint is SHA256:jggaAYjerBQyxtVOBnR/GoC+9TlCBy5Y6giz9nBPydQ.
ECDSA key fingerprint is MD5:d5:a1:8f:c9:64:8d:e2:62:c2:d7:06:9a:d3:fc:0d:dd.
Are you sure you want to continue connecting (yes/no)?
slave1:
----------
retcode:
stderr:
stdout:
The host key needs to be accepted, to auto accept run salt-ssh with the -i flag:
The authenticity of host '10.0.0.211 (10.0.0.211)' can't be established.
ECDSA key fingerprint is SHA256:jggaAYjerBQyxtVOBnR/GoC+9TlCBy5Y6giz9nBPydQ.
ECDSA key fingerprint is MD5:d5:a1:8f:c9:64:8d:e2:62:c2:d7:06:9a:d3:fc:0d:dd.
Are you sure you want to continue connecting (yes/no)?
[root@slave1 ~]# salt-ssh '*' test.ping -i
slave1:
True
slave2:
True
4. “-r” 远程执行命令参数
[root@slave1 ~]# salt-ssh '*' -r 'uptime'
slave1:
----------
retcode:
stderr:
stdout:
root@10.0.0.211's password:
03:26:49 up 3:38, 2 users, load average: 0.01, 0.08, 0.13
slave2:
----------
retcode:
stderr:
stdout:
root@10.0.0.212's password:
03:26:49 up 10:02, 1 user, load average: 0.00, 0.01, 0.05
1. 安装salt-ssh

2 常用模块和jinja模板
参考：https://www.unixhot.com/docs/saltstack/ref/states/highstate.html
2.1 状态模块特点：
1）状态是不可以回滚的。
2）写好的状态模块要支持多次执行。
2.2 pkg 模块
pkg模块是虚拟的，根据操作系统的不同，调用相关的工具安装操作系统。
参考：https://www.unixhot.com/docs/saltstack/ref/states/all/salt.states.pkg.html#module-salt.states.pkg
pkg模块常用方法：
pkg.installed 安装
pkg.latest 确保最新版本
pkg.remove 卸载
pkg.purge 卸载并且删除配置文件
使用pkg模块安装多个软件：
lamp-pkg:
pkg-installed:
- pkgs:
- httpd
- php
- mysql
- maridb-server
- php-mysql
- php-cli
- php-mbstring
2.3 file模块
参考：https://www.unixhot.com/docs/saltstack/ref/states/all/salt.states.file.html#module-salt.states.file
使用样例：
apache-config:
file.managed:
- name: /etc/httpd/conf/httpd.conf
- source: salt://files/httpd.conf
- user: root
- group: root
- mode: 644
2.3 service模块
样例：
apache-services:
service.running:
- name: httpd
- enable: True # 允许开机启动
- reload: True # 允许重载
2.4 状态间关系
- 1我依赖谁？ require
- 2我被谁依赖？ require_in
- 3我监控谁？ watch （包含require）
- 4我被谁监控？watch_in
- 5我引用谁？include
- 6我扩展谁？用到再说。
使用举例：
#我依赖谁？ require apache-services:
service.running:
- name: httpd
- enable: True
- reload: True
- require: # 他们都正常执行了，我才执行。
- pkg: lamp-pkg
- file: apapche-config #我被谁依赖？（谁依赖我？）
mysql-config:
file.managed:
- name: /etc/my.conf
- source: salt://lamp/files/my.cnf
- user: root
- gropu: root
- mode: 644
- require_in: # 和 require
- service: mysql-service #我监控谁？
#如果配置文件修改了，就重启服务。
apache-services:
service.running:
- name: httpd
- enable: True
- reload: True
- require:
- pkg: lamp-pkg
- file: apapche-config
- watch:
- file: apache-config 1.如果监控到apache-config的状态发生改变（就是配置文件改变了），就重载服务。
2.这里需要注意，如果加上了relaod : True 就是重载，如果没有就是重启。
2.5 jinja模板
参考文档：http://docs.jinkan.org/docs/jinja2/
使用背景：
有100台机器，有一个配置文件需要更改为本机的ip地址。最佳实践就是通过jinja模版来做。
二种分割符：
{{...}} 表示变量的引用。
{%...%} 表示表达式
jinja模版使用方法：
1）相当于在jinja模版里，定义了一个变量，模版配置文件里面再去调用。
2）可以在模版文件里，也可以写在sls文件里，然后模版文件直接调用。
- template: jinja #告诉File模块，你要使用jinja模版 - defaults: #列出参数列表
PORT: 80 {{ PORT }} #模版文件里面进行引用
例子：
[root@slave1 ~]# vim /srv/salt/prod/redis/init.sls
redis-install:
pkg.installed:
- name: redis redis-config:
file.managed:
- name: /etc/redis.conf
- source: salt://redis/files/redis.conf
- user: root
- group: root
- mode: 644
- template: jinja #告诉模板使用jinja
defaults:
PORT: 6379 #定义的参数
IPADDR: {{ grains['fqdn_ip4'][0] }} #获取主机ip redis-service:
service.running:
- name: redis
- enable: True
- reload: True
在模板文件中定义jinja模板
[root@slave1 ~]# vim /srv/salt/prod/redis/files/redis.conf
port {{ PORT }} #要传递端口
bind {{ IPADDR }} #传递要获取的主机ip
3 配置管理
3.1 状态的含义
States是Saltstack中的配置语言，在日常进行配置管理时需要编写大量的States文件。比如我们需要安装一个包，然后管理一个配置文件，最后保证某个服务正常运行。
这里就需要我们编写一些states sls文件（描述状态配置的文件）去描述和实现我们的功能。编写的states sls文件都是YAML语法，
states sls文件也支持使用Python语言编写。
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
例如安装Apache，如下：
[root@slave1 apache]# vim /srv/salt/base/apache/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
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
3.2 LAMP的状态设计与实现
3.2.1 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
3.2.2 LAMP状态模块编写及部署实现
提示：master：提前装好httpd,php，mysql用于配置文件的生成。
否则会因为服务配置文件没有内容造成服务无法正常启动。
