  • 系统架构图

    SaltStack项目实战一

1.项目准备

1.1 系统信息

[root@linux-node1 ~]# cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core) 
[root@linux-node1 ~]# uname -r
3.10.0-327.18.2.el7.x86_64
[root@linux-node1 ~]# ifconfig eth0|awk -F "[ :]+" 'NR==2{print $3}'
192.168.56.11
[root@linux-node1 ~]# hostname	
linux-node1.example.com
#node2主机名为linux-node2.example.com,IP为192.168.56.12,其余配置相同

1.2 功能模块管理

设置单独的目录:haproxy 、nginx 、php 、mysql 、memcached (尽可能的全面、独立)

1.3 业务模块分类

根据业务类型划分:如Web服务 、论坛BBS(使用include)

1.4 Salt环境配置

开发 ==> 测试(功能测试环境、性能测试环境、自动化测试环境) ==> 预生产 ==> 生产

  • 1.base 基础环境

[root@linux-node1 ~]# vi /etc/salt/master	#修改file_roots,创建base和prod目录,保存重启master
448 # The file server works on environments passed to the master, each environment
449 # can have multiple root directories, the subdirectories in the multiple file
450 # roots cannot match, otherwise the downloaded files will not be able to be
451 # reliably ensured. A base environment is required to house the top file.
452 # Example:
453 # file_roots:
454 #   base:
455 #     - /srv/salt/
456 #   dev:
457 #     - /srv/salt/dev/services
458 #     - /srv/salt/dev/states
459 #   prod:
460 #     - /srv/salt/prod/services
461 #     - /srv/salt/prod/states
462 #
463 file_roots:
464   base:
465     - /srv/salt/base		#base基础环境目录
466   prod:
467     - /srv/salt/prod		#prod生产环境目录
619 ##########################################
620 # Salt Pillars allow for the building of global data that can be made selectively
621 # available to different minions based on minion grain filtering. The Salt
622 # Pillar is laid out in the same fashion as the file server, with environments,
623 # a top file and sls files. However, pillar data does not need to be in the
624 # highstate format, and is generally just key/value pairs.
625 pillar_roots:
626   base:
627     - /srv/pillar/base		#pillar目录设置
628   prod:
629     - /srv/pillar/prod
==============================================
[root@linux-node1 /]# mkdir -p /srv/salt/{base,prod} /srv/pillar/{base,prod}
[root@linux-node1 /]# tree srv
srv
├── pillar
│   ├── base
│   └── prod
└── salt

    └── prod
[root@linux-node1 /]# cd /srv/salt/base
[root@linux-node1 /srv/salt/base]# mkdir init
[root@linux-node1 /srv/salt/base]# ll
drwxr-xr-x 2 root root 6 Jul 27 21:32 init

init目录--环境初始化

1.dns配置

[root@linux-node1 /srv/salt/base/init]# cat dns.sls
/etc/resolv.conf:
  file.managed:
    - source: salt://init/files/resolv.conf		#salt://根据配置相当于/srv/salt/base目录
    - user: root
    - group: root
    - mode: 644
[root@linux-node1 /srv/salt/base/init]# mkdir files
[root@linux-node1 /srv/salt/base/init]# cd files
[root@linux-node1 /srv/salt/base/init/files]# cat resolv.conf	#把系统dns配置文件拷贝到files目录下
# Generated by NetworkManager
nameserver 192.168.56.2
# No nameservers found; try putting DNS servers into your
# ifcfg files in /etc/sysconfig/network-scripts like so:
#
# DNS1=xxx.xxx.xxx.xxx
# DNS2=xxx.xxx.xxx.xxx
# DOMAIN=lab.foo.com bar.foo.com

2.histroy记录时间

[root@linux-node1 /srv/salt/base/init]# cat history.sls
/etc/profile:
  file.append:		#文件追加,在/etc/porfile文件末尾追加一行
    - text:
      - export HISTTIMEFORMAT="%F %T `whoami` "	  #追加内容

3.记录命令操作

[root@linux-node1 /srv/salt/base/init]# cat audit.sls 
/etc/bashrc:
  file.append:
    - text:
      - export PROMPT_COMMAND='{ msg=$(history 1 | { read x y; echo $y; });logger "[euid=$(whoami)]":$(who am i):[`pwd`]"$msg"; }'

4.内核参数优化

[root@linux-node1 /srv/salt/base/init]# cat sysctl.sls 
net.ipv4.ip_local_port_range:	#设置本地可用的端口范围,作为客户端发起连接时使用
  sysctl.present:		#使用了sysctl里的一个模块
    - value: 10000 65000	#随机分配端口范围
fs.file-max:
  sysctl.present:
    - value: 2000000		#文件打开数限制,Linux中一切皆文件
net.ipv4.ip_forward:		#打开IP转发
  sysctl.present:
    - value: 1
vm.swappiness:			#交换分区使用权重值,让系统尽量不使用
  sysctl.present:
    - value: 0
[root@linux-node1 /srv/salt/base/init]# cat /proc/sys/fs/file-max
183487
[root@linux-node1 /srv/salt/base/init]# cat /proc/sys/vm/swappiness 
30
#其余调优参数可以自行添加即可

5.安装yum仓库

[root@linux-node1 /srv/salt/base/init]# cat epel.sls
yum_repo_release:
  pkg.installed:
    - sources:			#指定一个地址,pkg安装模块会从配置的url安装服务
      - epel-release: http://mirrors.aliyun.com/epel/epel-release-latest-7.noarch.rpm

6.安装zabbix-agent

[root@linux-node1 /srv/salt/base/init]# cat zabbix-agent.sls 
zabbix-agent:
  pkg.installed:
    - name: zabbix-agent	
  file.managed:
    - name: /etc/zabbix/zabbix_agentd.conf	#配置文件管理
    - source: salt://init/files/zabbix_agentd.conf	#zabbix-agent配置文件放置路径
    - template: jinja		#jinja模版
    - backup: minion		#配置文件发生变动master会本地保存一份(在/var/cache/salt/minion/file_backup/etc/zabbix目录下),便于回滚
    - defaults:
      Zabbix_Server: {{ pillar['Zabbix_Server'] }}	#pillar配置Zabbix_Server的key值
      Hostname: {{ grains['fqdn'] }}			#主动模式配置
    - require:
      - pkg: zabbix-agent	#依赖安装包
   service.running:
    - enable: True		#开机自动运行
    - watch:
      - pkg: zabbix-agent	#监控包和文件,发生改变则重启
      - file: zabbix-agent

zabbix_agentd.conf.d:
  file.directory:
    - name: /etc/zabbix/zabbix_agentd.d
    - watch_in:			#被zabbix-agent依赖
      - service: zabbix-agent
    - require:
      - pkg: zabbix-agent
      - file: zabbix-agent

[root@linux-node1 /srv/salt/base/init/files]# cd files
[root@linux-node1 /srv/salt/base/init/files]# vi zabbix_agentd.conf
Server={{ Zabbix_Server }}	#配置pillar的key值
[root@linux-node1 /srv/pillar/base]# cd /srv/pillar/base/	#创建pillar文件
[root@linux-node1 /srv/pillar/base]# mkdir zabbix && cd zabbix && vi agent.sls
[root@linux-node1 /srv/pillar/base/zabbix]# cat agent.sls 
Zabbix_Server: 192.168.56.11	#要与zabbix-agent.sls中定义的值要一致
[root@linux-node1 /srv/pillar/base]# cat top.sls 	#pillar文件需定义top file指定执行
base:
