SaltStack 架构自动部署 03

架构图

模块化部署

系统模块:系统优化,内核参数,网络参数

功能模块:如:nginx,tomcat,

业务模块:

1.在salt-master端修改配置文件

[root@01 salt]# vim /etc/salt/master


file_roots:
  base:  #初始环境
    - /srv/salt/base
  prod:  #生产环境
    - /srv/salt/prod
  test:   #测试环境
    - /srv/salt/test

　　

[root@01 salt]# tree
.
├── base
│   ├── init
│   │   ├── audit.sls
│   │   ├── dns.sls
│   │   ├── env_init.sls
│   │   ├── files
│   │   │   └── resolv.conf
│   │   ├── history.sls
│   │   └── sysctl.sls
│   └── top.sls
├── base.tar.gz
├── prod
│   ├── cluster
│   │   ├── files
│   │   │   └── haproxy-outside.cfg
│   │   └── haproxy-outside.sls
│   ├── haproxy
│   │   ├── files
│   │   │   ├── haproxy-1.6.9.tar.gz
│   │   │   └── haproxy.init
│   │   └── install.sls
│   └── pkg
│       └── pkg-init.sls
└── test

10 directories, 14 files

　　

2.创建目录

mkdir /srv/salt/prod/pkg    ##生产上一些包放在这
mkdir /srv/salt/prod/haproxy
mkdir /srv/salt/prod/haproxy/files #haproxy 包文件
mkdir /srv/salt/prod/cluster #安装前端后端
mkdir /srv/salt/prod/cluster/files  #haproxy配置文件



3.配置salt系统环境

[root@01 base]# pwd
/srv/salt/base
[root@01 base]# cat top.sls 
base:
  '*':
    - init.env_init      #初始环境

prod:  #生产环境
  'wawa01':   #主机名称
    - cluster.haproxy-outside   
  'www.wawa8888.com':
    - cluster.haproxy-outside

　

haproxy依赖的包,这里单独写在一个sls,有条理点

[root@01 ~]# cd /srv/salt/prod/pkg/
[root@01 pkg]# ls
pkg-init.sls
[root@01 pkg]# cat pkg-init.sls 
pkg-init:
  pkg.installed:
    - names:
      - gcc
      - gcc-c++
      - glibc
      - make
      - autoconf
      - openssl
      - openssl-devel

　　

4.写haproxy状态文件

[root@01 haproxy]# cd /srv/salt/prod/haproxy
[root@01 haproxy]# ls
files  install.sls
[root@01 haproxy]# cat install.sls 
include:
  - pkg.pkg-init

haproxy-install:    
  file.managed:    #两个空格
    - name: /usr/local/src/haproxy-1.6.9.tar.gz #四个空格右边一个空格
    - source: salt://haproxy/files/haproxy-1.6.9.tar.gz
    - user: root
    - group: root
    - mode: 755
  cmd.run:        
    - name: cd /usr/local/src && tar zxf haproxy-1.6.9.tar.gz && cd haproxy-1.6.9 && make TARGET=linux26 PREFIX=/usr/local/haproxy && make install PREFIX=/usr/local/haproxy
    - unless: test -d /usr/local/haproxy   
    - require:    
      - pkg: pkg-init
      - file: haproxy-install  
/etc/init.d/haproxy:  
  file.managed:
    - source: salt://haproxy/files/haproxy.init
    - user: root
    - group: root
    - mode: 755
    - require:
      - cmd: haproxy-install
  cmd.run:
    - name: chkconfig --add haproxy
    - unless: chkconfig --list | grep haproxy
    - require:
      - file: /etc/init.d/haproxy

net.ipv4.ip_nonlocal_bind:
  sysctl.present:
    - value: 1

haproxy-config-dir:
  file.directory:
    - name: /etc/haproxy
    - user: root
    - group: root
    - mode: 755

　　

5.初始文件修改,

haproxy-1.6.9.tar.gz  #提前放好包

[root@01 files]# ls
haproxy-1.6.9.tar.gz  haproxy.init
[root@01 files]# 
[root@01 files]# 
[root@01 files]# grep "BIN=" haproxy.init 
BIN=/usr/local/haproxy/sbin/$BASENAME

　　

[root@01 cluster]# cd /srv/salt/prod/cluster
[root@01 cluster]# ls
files  haproxy-outside.sls
[root@01 cluster]# cat haproxy-outside.sls 
include:
  - haproxy.install

haproxy-service:
  file.managed:
    - name: /etc/haproxy/haproxy.cfg
    - source: salt://cluster/files/haproxy-outside.cfg
    - user: root
    - group: root
    - mode: 644
  service.running:
    - name: haproxy
    - enable: True
    - reload: True
    - require: 
      - cmd: /etc/init.d/haproxy
    - watch:
      - file: haproxy-service

　　

　

cd /srv/salt/prod/cluster/files

[root@01 files]# ls
haproxy-outside.cfg

　重启 systemctl restart salt-master

   测试 salt '*' state.highstate test=True
   高级模式执行 salt '*' state.highstate
