SaltStack项目实战（六）

SaltStack项目实战

系统架构图

一、初始化

1、salt环境配置，定义基础环境、生产环境（base、prod）

vim /etc/salt/master
修改file_roots
file_roots:
  base:
    - /srv/salt/base
  prod:
    - /srv/salt/prod
	
mkdir -p /srv/salt/base 
mkdir -p /srv/salt/prod

pillar配置

vim /etc/salt/master
修改pillar_roots
pillar_roots:
  base:
    - /srv/pillar/base
  pord:
    - /srv/pillar/prod
	
mkdir -p /srv/pillar/base 
mkdir -p /srv/pillar/prod

服务重启 systemctl restart salt-master

2、salt base环境初始化：

mkdir -p /srv/salt/base/init  # 环境初始化目录
mkdir -p /srv/salt/base/init/files  # 配置文件目录

1）dns配置

准备dns配置文件，放入/srv/salt/base/init/files目录下

cp /etc/resolv.conf /srv/salt/base/init/files/

vi /srv/salt/base/init/dns.sls
/etc/resolv.conf:
  file.managed:
    - source: salt://init/files/resolv.conf
    - user: root
    - gourp: root
    - mode: 644

2）histroy记录时间

vi /srv/salt/base/init/history.sls
/etc/profile:
  file.append:
    - text:
      - export HISTTIMEFORMAT="%F %T `whoami` "

3）记录命令操作

vi /srv/salt/base/init/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

vi /srv/salt/base/init/sysctl.sls
net.ipv4.ip_local_port_range:
  sysctl.present:
    - value: 10000 65000
fs.file-max:
  sysctl.present:
    - value: 2000000
net.ipv4.ip_forward:
  sysctl.present:
    - value: 1
vm.swappiness:
  sysctl.present:
    - value: 0

5）安装yum仓库

vi /srv/salt/base/init/epel.sls
yum_repo_release:
  pkg.installed:
    - sources:
      - epel-release: http://mirrors.aliyun.com/epel/epel-release-latest-7.noarch.rpm
    - unless: rpm -qa | grep epel-release-latest-7

6）安装zabbix-agent

准备zabbix-agent配置文件，放入/srv/salt/base/init/files目录下

cp /etc/zabbix/zabbix_agentd.conf /srv/salt/base/init/files/

修改 vi /etc/zabbix/zabbix_agentd.conf

vi /srv/salt/base/init/zabbix_agent.sls
zabbix-agent:
  pkg.installed:
    - name: zabbix-agent
  file.managed:
    - name: /etc/zabbix/zabbix_agentd.conf
    - source: salt://init/files/zabbix_agentd.conf
    - template: jinja
    - backup: minion
    - defaults:
      Server: {{ pillar['zabbix-agent']['Zabbix_Server'] }}
	  Hostname: {{ grains['fqdn'] }}
    - require:
      - pkg: zabbix-agent
  service.running:
    - enable: True
    - watch:
      - pkg: zabbix-agent
      - file: zabbix-agent

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

备注：“- backup: minion”表示备份，如果文件改动，会将之前的文件备份到/var/cache/salt/file_backup目录下

7）编写init.sls总文件，引用其它文件

vi /srv/salt/base/init/init.sls
include:
  - init.dns
  - init.history
  - init.audit
  - init.sysctl
  - init.epel
  - init.zabbix_agent

执行命令： salt "*" state.sls init.init

执行结果

8）创建top文件

vi /srv/salt/base/top.sls
base:
  '*':
    - init.init

测试 salt "*" state.highstate test=True

执行 salt "*" state.highstate

3、pillar base初始化

1）zabbix agent配置，指定zabbix server地址，用于sls文件引用

mkdir -p /srv/pillar/base/zabbix
vi /srv/pillar/base/zabbix/agent.sls
zabbix-agent:
  Zabbix_Server: 192.168.137.11

编写top，引用/srv/pillar/base/zabbix/agent文件

vi /srv/pillar/base/top.sls
base:
  '*':
    - zabbix.agent

测试 salt '*' pillar.items

二、haproxy

官网 http://www.haproxy.com/

mkdir -p /srv/salt/prod/modules/haproxy
mkdir -p /srv/salt/prod/modules/keepalived
mkdir -p /srv/salt/prod/modules/memcached
mkdir -p /srv/salt/prod/modules/nginx
mkdir -p /srv/salt/prod/modules/php
mkdir -p /srv/salt/prod/modules/pkg
mkdir -p /srv/salt/prod/cluster
mkdir -p /srv/salt/prod/modules/haproxy/files/
mkdir -p /srv/salt/prod/cluster/files

1）系统gcc编译包等

vi /srv/salt/prod/pkg/make.sls
make-pkg:
  pkg.installed:
    - names:
      - gcc
      - gcc-c++
      - glibc
      - make
      - autoconf
      - openssl
      - openssl-devel
      - pcre
      - pcre-devel

2）自安装

cd /usr/local/src	  
tar xvf haproxy-1.6.3.tar.gz
cd haproxy-1.6.3/
make TARGET=linux2628 PREFIX=/usr/local/haproxy-1.6.3
make install PREFIX=/usr/local/haproxy-1.6.3
ln -s /usr/local/haproxy-1.6.3 /usr/local/haproxy

修改启动脚本，放入salt下

vi /usr/local/src/haproxy-1.6.3/examples/haproxy.init
BIN=/usr/local/haproxy/sbin/$BASENAME
cp /usr/local/src/haproxy-1.6.3/examples/haproxy.init /srv/salt/prod/modules/haproxy/files/

haproxy-1.6.3.tar.gz安装包放入/srv/salt/prod/modules/haproxy/files/目录下

3）创建install.sls文件，用于安装haproxy

vi /srv/salt/prod/modules/haproxy/install.sls
include:
  - modules.pkg.make
  
haproxy-install:
  file.managed:
    - name: /usr/local/src/haproxy-1.6.3.tar.gz
    - source: salt://modules/haproxy/files/haproxy-1.6.3.tar.gz
    - mode: 755
    - user: root
    - group: root
  cmd.run:
    - name: cd /usr/local/src && tar zxf haproxy-1.6.3.tar.gz && cd haproxy-1.6.3 && make TARGET=linux2628 PREFIX=/usr/local/haproxy-1.6.3 && make install PREFIX=/usr/local/haproxy-1.6.3 && ln -s /usr/local/haproxy-1.6.3 /usr/local/haproxy
    - unless: test -L /usr/local/haproxy
    - require:
      - pkg: make-pkg
      - file: haproxy-install

haproxy-init:
  file.managed:
    - name: /etc/init.d/haproxy
    - source: salt://modules/haproxy/files/haproxy.init
    - mode: 755
    - user: root
    - group: root
    - require_in:
      - file: haproxy-install
  cmd.run:
    - name: chkconfig --add haproxy
    - unless: chkconfig --list| grep haproxy
 
net.ipv4.ip_nonlocal_bind:
  sysctl.present:
    - value: 1

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

备注： “- unless” 如果unless后面的命令返回为True，那么就不执行当前状态命令

4）创建haproxy配置文件

vi /srv/salt/prod/cluster/files/haproxy-outside.cfg
global
maxconn 100000
chroot /usr/local/haproxy
uid 99
gid 99
daemon
nbproc 1
pidfile /usr/local/haproxy/logs/haproxy.pid
log 127.0.0.1 local3 info
defaults
option http-keep-alive
maxconn 100000
mode http
timeout connect 5000ms
timeout client 50000ms
timeout server 50000ms
listen stats
mode http
bind 0.0.0.0:8888
stats enable
stats uri /haproxy-status
stats auth haproxy:saltstack
frontend frontend_www_example_com
bind 192.168.137.21:80
mode http
option httplog
log global
default_backend backend_www_example_com
backend backend_www_example_com
option forwardfor header X-REAL-IP
option httpchk HEAD / HTTP/1.0
balance source

server web-node1 192.168.137.11:8080 check inter 2000 rise 30 fall 15
server web-node2 192.168.137.12:8080 check inter 2000 rise 30 fall 15

创建haproxy-outside.sls文件，用于配置haproxy

vi /srv/salt/prod/cluster/haproxy-outside.sls
include:
  - modules.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: haproxy-install
    - watch:
      - file: haproxy-service

5）配置top file

vi /srv/pillar/base/top.sls
base:
  '*':
    - zabbix.agent
prod:
  'linux-node*':
    - cluster.haproxy-outside

测试 salt "*" state.highstate test=True

执行 salt "*" state.highstate

结果：

三、keepalived

1）创建files目录，将keepalived-1.2.17.tar.gz安装包、keepalived.sysconfig、keepalived.init放入

mkdir -p /srv/salt/prod/modules/keepalived/files

2）创建install.sls文件

vi /srv/salt/prod/modules/keepalived/install.sls
{% set keepalived_tar = 'keepalived-1.2.17.tar.gz' %}
{% set keepalived_source = 'salt://modules/keepalived/files/keepalived-1.2.17.tar.gz' %}

keepalived-install:
  file.managed:
    - name: /usr/local/src/{{ keepalived_tar }}
    - source: {{ keepalived_source }}
    - mode: 755
    - user: root
    - group: root
  cmd.run:
    - name: cd /usr/local/src && tar zxf {{ keepalived_tar }} && cd keepalived-1.2.17 && ./configure --prefix=/usr/local/keepalived --disable-fwmark && make && make install
    - unless: test -d /usr/local/keepalived
    - require:
      - file: keepalived-install

/etc/sysconfig/keepalived:
  file.managed:
    - source: salt://modules/keepalived/files/keepalived.sysconfig
    - mode: 644
    - user: root
    - group: root

/etc/init.d/keepalived:
  file.managed:
    - source: salt://modules/keepalived/files/keepalived.init
    - mode: 755
    - user: root
    - group: root

keepalived-init:
  cmd.run:
    - name: chkconfig --add keepalived
    - unless: chkconfig --list | grep keepalived
    - require:
      - file: /etc/init.d/keepalived

/etc/keepalived:
  file.directory:
    - user: root
    - group: root

执行命令：salt '*' state.sls modules.keepalived.install saltenv=prod

3）创建keepalived配置文件haproxy-outside-keepalived.conf

! Configuration File for keepalived
global_defs {
   notification_email {
     saltstack@example.com
   }
   notification_email_from keepalived@example.com
   smtp_server 127.0.0.1
   smtp_connect_timeout 30
   router_id {{ROUTEID}}
}

vrrp_instance haproxy_ha {
state {{STATEID}}
interface eth0
    virtual_router_id 36
priority {{PRIORITYID}}
    advert_int 1
authentication {
auth_type PASS
        auth_pass 1111
    }
    virtual_ipaddress {
       192.168.137.21
    }
}

创建haproxy-outside-keepalived.sls

vi /srv/salt/prod/cluster/haproxy-outside-keepalived.sls
include:
  - modules.keepalived.install

keepalived-server:
  file.managed:
    - name: /etc/keepalived/keepalived.conf
    - source: salt://cluster/files/haproxy-outside-keepalived.conf
    - mode: 644
    - user: root
    - group: root
    - template: jinja
    {% if grains['fqdn'] == 'linux-node1.example.com' %}
    - ROUTEID: haproxy_ha
    - STATEID: MASTER
    - PRIORITYID: 150
    {% elif grains['fqdn'] == 'linux-node2.example.com' %}
    - ROUTEID: haproxy_ha
    - STATEID: BACKUP
    - PRIORITYID: 100
    {% endif %}
  service.running:
    - name: keepalived
    - enable: True
    - watch:
      - file: keepalived-server

4）将keepalived加入top FILE

vi /srv/salt/base/top.sls
base:
  '*':
    - init.init
prod:
  'linux-node*':
    - cluster.haproxy-outside
    - cluster.haproxy-outside-keepalived

测试 salt "*" state.highstate test=True

执行 salt "*" state.highstate
