本文首先介绍saltstack的项目环境准备,进行软件安装与配置,其次对项目整体部署,希望对您的学习有所帮助。
本文来自于个人博客,由火龙果软件Alice编辑、推荐。

项目架构规划

后端web服务器使用Nginx+Php作为站点,通过HAproxy做负载均衡,Keepalived做高可用

说明: 关闭防火墙、selinux、时间同步等

host绑定

[root@salt-master ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.1.30 salt-master
192.168.1.31 salt-minion01
192.168.1.32 salt-minion02
192.168.1.33 salt-minion03
192.168.1.34 salt-minion04
[root@salt-master ~]# for i in `seq 4`; do scp /etc/hosts 192.168.1.3$i:/etc/hosts ; done

软件安装

参考地址

1)Master上软件安装

[root@salt-master ~]# yum -y install https://mirrors.aliyun.com/saltstack/yum/redhat/salt-repo-latest-2.el7.noarch.rpm
[root@salt-master ~]# sed -i "s/repo.saltstack.com/mirrors.aliyun.com\/saltstack/g" /etc/yum.repos.d/salt-latest.repo
[root@salt-master ~]# yum -y install salt-master
[root@salt-master ~]# systemctl enable salt-master
[root@salt-master ~]# systemctl start salt-master

2)Minion上软件安装并配置

# yum -y install https://mirrors.aliyun.com/saltstack/yum/redhat/salt-repo-latest-2.el7.noarch.rpm
# yum -y install salt-minion
# cp /etc/salt/minion{,.back}
# sed -i '/#master: /c\master: salt-master' /etc/salt/minion
# systemctl enable salt-minion
# systemctl start salt-minion

Master上认证

[root@salt-master ~]# systemctl restart salt-master
[root@salt-master ~]# salt-key -L
Accepted Keys:
Denied Keys:
Unaccepted Keys:
salt-minion01
salt-minion02
salt-minion03

Rejected Keys:

[root@salt-master ~]# salt-key -A -y
The following keys are going to be accepted:
Unaccepted Keys:
salt-minion01
salt-minion02
salt-minion03

Master上state编写

state环境设置

说明:该案例在prod环境下配置,在prod下面创建了一个modules的目录,所有的安装配置都放在这个目录下面了,里面分别又对应创建了对应的软件目录,每个软件目录下面的files目录用来存放的是软件包或者配置文件模板

[root@salt-master ~]# vim /etc/salt/master
file_roots:
base:
- /srv/salt/base
test:
- /srv/salt/test
prod:
- /srv/salt/prod
dev:
- /srv/salt/dev
[root@salt-master ~]# systemctl restart salt-master
[root@salt-master ~]# mkdir -p /srv/salt/{base,
test,prod,dev}
[root@salt-master ~]# mkdir -p /srv/salt/prod/modules/{nginx,php,mysql,haproxy,
keepalived,lnmp}/files
[root@salt-master ~]# mkdir /srv/salt/prod/modules/user
[root@salt-master ~]# tree /srv/salt/prod/modules/
/srv/salt/prod/modules/

"salt-minion0[3-4]":
- modules.lnmp.www

2)执行高级状态

[root@salt-master ~]# salt '*' state.highstate

3)访问测试

haproxy

1)配置文件准备

[root@salt-master ~]# cd /srv/salt/prod/modules/haproxy/
[root@salt-master haproxy]# tree
.
├── files
│ └── haproxy.cfg
├── install.sls
└── service.sls
directory, 3 files

2)install.sls

[root@salt-master haproxy]# cat install.sls
haproxy-install:
pkg.installed:
- name: haproxy

3)service.sls

service.running:
- name: haproxy
- enable: True
- require:
- pkg: haproxy-install
- file: haproxy-config
- watch:
- file: haproxy-config

keepalived

1)配置文件准备

[root@salt-master ~]# cd /srv/salt/prod/modules/keepalived/
[root@salt-master keepalived]# tree
.
├── files
│ └── keepalived.conf
├── install.sls
└── service.sls
directory, 3 files

2)install.sls

[root@salt-master keepalived]# cat install.sls
keepalived-install:
pkg.installed:
- name: keepalived

3)service.sls

[root@salt-master keepalived]# cat service.sls
#引入keepalived安装的sls
include:
- modules.keepalived.install

#keepalived配置文件
keepalived-config:
file.managed:
- name: /etc/keepalived/keepalived.conf
- source: salt://modules/keepalived/files/keepalived.conf
- user: root
- group: root
- mode: 644
- require:
- pkg: keepalived-install
- template: jinja
- defaults:
{% if grains['fqdn'] == "salt-minion01" %}
ROUTER_ID: saltstack01
STATE: MASTER
PRIORITY: 150
{% elif grains['fqdn'] == "salt-minion02" %}
ROUTER_ID: saltstack02
STATE: BACKUP
PRIORITY: 100
{% endif %}

#启动keepalived
keepalived-service:
service.running:
- name: keepalived
- enable: True
- require:
- pkg: keepalived-install
- file: keepalived-config
- watch:
- file: keepalived-config

整体部署

1)top file 编写

[root@salt-master ~]# cat /srv/salt/base/top.sls
prod:
"salt-minion0[3-4]":
- modules.lnmp.www

"salt-minion0[1-2]":
- modules.haproxy.service
- modules.keepalived.service

2)高级状态执行

[root@salt-master ~]# salt '*' state.highstate

3)测试

访问192.168.1.31和192.168.1.32的状态页

访问VIP192.168.1.100

通过上面测试可看到可以成功访问lnmp站点,并且haproxy也ok。访问所有四台服务器都可以得到phpinfo页面,而在生产环境中,我们只是对外提供vip即可。

项目总结

1)整体环境查看

[root@salt-master ~]# tree /srv/salt/prod/modules/
/srv/salt/prod/modules/
├── haproxy
│ ├── files
│ │ └── haproxy.cfg
│ ├── install.sls
│ └── service.sls
├── keepalived
│ ├── files
│ │ └── keepalived.conf
│ ├── install.sls
│ └── service.sls
├── lnmp
│ ├── files
│ │ ├── index.php
│ │ └── www.conf
│ └── www.sls
├── mysql
│ ├── files
│ │ └── my.cnf
│ ├── install.sls
│ └── service.sls
├── nginx
│ ├── files
│ │ ├── nginx-1.12.2.tar.gz
│ │ ├── nginx-1.16.0.tar.gz
│ │ ├── nginx.conf.template
│ │ └── nginx.service.template
│ ├── install.sls
│ └── service.sls
├── php
│ ├── files
│ │ ├── php-5.6.40.tar.gz
│ │ ├── php-fpm.conf.template
│ │ ├── php-fpm.service.template
│ │ ├── php-fpm.template
│ │ └── php.ini.template
│ ├── install.sls
│ └── service.sls
├── pkg.sls
└── user
└── www.sls
directories, 27 files

2)如果需要在某台服务器上面单独部署某一部分,参考以下写法:

[root@salt-master ~]# cat /srv/salt/base/top.sls
#部署lnmp及haproxy+keepalived
prod:
"salt-minion0[3-4]":
- modules.lnmp.www

"salt-minion0[1-2]":
- modules.haproxy.service
- modules.keepalived.service

#单实例操作说明:
prod:
"salt-minion04":
- modules.nginx.service #单独安装nginx时
- modules.mysql.service #单独安装mysql时
- modules.php.service #单独安装php时
- modules.keepalived.service #单独安装keepalived时
- modules.haproxy.service #单独安装haproxy时

"salt-minion03":
- modules.lnmp.www #单独部署lnmp环境时
