SaltStack部署服务及配置管理apache+php-第二篇

实验目标

1.使用SaltStack部署apache和php,

2.使用salt管理httpd.conf配置文件配置访问info.php使用账户密码

3.在salt里面增加对conf.d目录进行配置管理

4.如何使用salt在追加文件内容

5.学会如何使用 watch require unless

实现步骤

修改master的配置文件，指定base环境路径，base环境是必须指定的

[root@linux-node1 base]# grep  -9  ^file_roots /etc/salt/master  |grep -v ^#
file_roots:
  base:
    - /srv/salt/base
  dev:
    - /srv/salt/dev
  test:
    - /srv/salt/test
  prod:
    - /srv/salt/prod

创建目录

[root@linux-node1 base]# mkdir -p /srv/salt/{base,dev,test,prod}
[root@linux-node1 base]# tree /srv/salt/
/srv/salt/
├── base
├── dev
├── prod
└── test

重启master

[root@linux-node1 base]# systemctl restart salt-master

在base目录下面创建一个web目录用于存放web相关的sls文件

[root@linux-node1 base]# mkdir -p web

cd到bash/web目录里面创建apache.sls文件

[root@linux-node1 base]# cd web/
[root@linux-node1 web]# cat apache.sls 
apache-install:   #id 名字自己取 需要形象一点， 一个id下面一个状态只能出现一次
  pkg.installed:  #pkg 是状态模块，installed 是模块里面的方法
    - name: httpd #方法里面的参数
apache-service:
  service.running:
    - name: httpd
    - enable: True #设置开机自动启动
#yaml里面格式有严格的要求，注释用#号，不能有table，- 两边需要空格，缩进用2个空格层级关系后面要加分号

执行状态模块部署服务

[root@linux-node1 base]# salt "linux-node2*" state.sls apache
linux-node2.example.com:
----------
          ID: apache-install
    Function: pkg.installed
        Name: httpd
      Result: True
     Comment: Package httpd is already installed.

          ID: apache-service
    Function: service.running
        Name: httpd
      Result: True

     Changes:   
              ----------
              httpd:
                  True

#此时node2 上面已经部署好了apache

高级状态的使用需要在master配置文件里面打开 state_top: top.sls并重启master

[root@linux-node1 web]# grep -n ^state_top /etc/salt/master
329:state_top: top.sls
[root@linux-node1 web]# systemctl restart salt-master

在bese环境目录下面添加top.sls

[root@linux-node1 base]# more top.sls 
base:
  'linux-node2.example.com':
    - web.apache
  'linux-node1.example.com':
    - web.apache
[root@linux-node1 base]# pwd
/srv/salt/base

执行高级模块方法，高级方法到 base下面找top.sls 文件编排告诉每个minion需要干什么，一般生产环境用高级状态多些

[root@linux-node1 base]#   salt "*" state.highstate 
linux-node1.example.com:
----------
          ID: apache-install
    Function: pkg.installed
        Name: httpd

上面我们使用了2个状态模块pkg和service，下面我们使用file文件配置模块

模块使用参考文档

https://www.unixhot.com/docs/saltstack/ref/states/all/salt.states.file.html#module-salt.states.file

在base/web目录下面添加一个lamp.sls，一般在添加里面的内容之前需要在外面找一台服务器进行测试拿到准确的包信息后再进行配置

[root@linux-node1 web]# cat lamp.sls
lamp-install:
pkg.installed:
- pkgs:
- httpd
- php
- php-pdo
- php-mysql

apache-config:
file.managed:
- name: /etc/httpd/conf/httpd.conf #服务实际使用的文件路径
- source: salt://web/files/httpd.conf #salt的源文件用于分发到minion上面路径是base目录下面的web 这里也支持http和ftp方式
- user: root
- group: root
- mode: 644

php-config:
file.managed:
- name: /etc/php.ini
- source: salt://web/files/php.ini
- user: root
- group: root
- mode: 644

lamp-service:
service.running:
- name: httpd
- enable: True

拷贝源文件到base/web目录下，这个根据自己的实际情况找源文件拷贝过来

[root@linux-node1 web]# cp /etc/httpd/conf/httpd.conf /srv/salt/base/web/files/
[root@linux-node1 web]# cp /etc/php.ini /srv/salt/base/web/files/

执行状态模块部署服务

[root@linux-node1 web]# salt "*" state.sls web.lamp

使用file模块下面的recurse方法进行apache的conf.d目录管理配置如下

apache-conf:
  file.recurse:
    - name: /etc/httpd/conf.d
    - source: salt://web/files/apache-conf.d

创建salt源目录，并拷贝数据导源文件目录，数据文件来源根据自己业务的实际情况

[root@linux-node1 ~]# mkdir /srv/salt/base/web/files/apache-conf.d
[root@linux-node1 ~]# cd /srv/salt/base/web/files/apache-conf.d/
[root@linux-node1 apache-conf.d]# cp -a /etc/httpd/conf.d/* .
[root@linux-node1 apache-conf.d]# ls
autoindex.conf php.conf README userdir.conf welcome.conf
[root@linux-node1 apache-conf.d]#

测试在files/apache-conf.d/welcome.conf 添加一行#xiewenming test

[root@linux-node1 files]# echo "#xieweming test" >> apache-conf.d/welcome.conf

验证目录管理是否生效

可以先使用test=True 只做测试，不会在minion节点上面真正执行，确认无问题后再让minion去执行

[root@linux-node1 files]# salt "linux-node2*" state.highstate test=True

apache-conf:
  file.recurse:

另外一种watc_in写法，我们只需要掌握一种就可以

使用require可以让各ID之间产生依赖关系，避免无效执行

比如执行apache-config ID之前要确保 lamp-install ID已经成功的完成了添加下面红色字体部分

lamp-install:
  pkg.installed:
    - pkgs:
      - httpd
      - php
      - php-pdo
      - php-mysql

apache-config:
  file.managed:
    - name: /etc/httpd/conf/httpd.conf
    - source: salt://web/files/httpd.conf
    - user: root
    - group: root
    - mode: 644
    - require:
      - pkg: lamp-install

测试apache php环境工作是否正常,在2个节点上的apache工作目录下创建phpinfo文件

[root@linux-node2 conf.d]# cd /var/www/html/
[root@linux-node2 html]# mkdir admin
[root@linux-node2 html]# cd admin/
[root@linux-node2 admin]# vi info.php
[root@linux-node2 admin]# cat info.php 
<?php
phpinfo()
?>

可以正常打开

现在使用salt添加访问phpinfo需要账号密码

在salt的apache的配置管理文件里面添加验证如下红色字体部分

[root@linux-node1 files]# pwd
/srv/salt/base/web/files
[root@linux-node1 files]#
[root@linux-node1 files]# tail -15 httpd.conf
#EnableMMAP off
EnableSendfile on
<Directory "/var/www/html/admin">
AllowOverride All
Order allow,deny
Allow from All
AuthUserFile /etc/httpd/conf/htpasswd_file
AuthName "hehe"
AuthType Basic
Require user admin
</Directory>
# Supplemental configuration
#
# Load config files in the "/etc/httpd/conf.d" directory, if any.
IncludeOptional conf.d/*.conf

在lamp.sls 里面添加一个名为apache-auth 状态ID并使用require指定依赖关系

[root@linux-node1 web]# pwd
/srv/salt/base/web
[root@linux-node1 web]# ls
apache.sls  files  lamp.sls
[root@linux-node1 web]# tail -10 lamp.sls 
    - name: /etc/httpd/conf.d
    - source: salt://web/files/apache-conf.d

apache-auth:
  pkg.installed:
    - name: httpd-tools
    - require_in:
      - cmd: apache-auth   #如果没有这个rpm包下面的cmd.run就不运行,指定依赖关系
  cmd.run:
    - name: htpasswd -bc /etc/httpd/conf/htpasswd_file admin admin #创建 账号为admin 密码为admin的密码文件

执行状态模块，验证没有报错

再次访问phpinfo就有验证了

但是上面有些小问题

当多次执行apache-auth状态模块的时候，密码文件会被重新创建并覆盖

解决办法：我们可以使用unless进行判断，unless 如果条件为真就执行，为假就不执行

修改apache-auth状态模块如下

[root@linux-node1 web]# tail -8 lamp.sls 
apache-auth:
  pkg.installed:
    - name: httpd-tools
    - require_in:
      - cmd: apache-auth   #如果没有这个rpm包下面的cmd.run就不运行,解决依赖关系
  cmd.run:
    - name: htpasswd -bc /etc/httpd/conf/htpasswd_file admin admin
    - unless: test -f /etc/httpd/conf/htpasswd_file #unless 不只限于用test 支持脚本等任何命令 只要判断 期返回结果0 或者1 0为真 1为假 就可以

再次执行lamp.sls状态模块，就解决了上面的问题

/etc/profile: #这里是ID的另一种用法，可以直接用文件的路径
file.append:

总结

1.添加状态模块的时候，应该自己得先在别的机器上面跑一遍流程在添加
2.状态模块中- source: salt://web/files/apache-conf.d #支持ftp或者http上面 base环境的路径
3.使用的时候要先测试 test=True
4.ID 有不同表示方式
5.状态模块需要执行模块执行才能生效
6.相同的业务用目录进行分类管理
7.sls文件是从上往下按照顺序执行
8.一个ID下面一个状态只能出现一次
9.pkg是虚拟的包管理,在不同系统下面包的安装命令不同比如 CentOS 和Ubuntu
10.watch 和watch_in require和require_in 在状态模块中可以统一用其中的一种
11.salt默认是有缓存的，可以无关紧要的配置重启进程刷新缓存
salt任务执行过程中不删除缓存目录里面的文件缓存目录默认为/var/cache/salt

SaltStack部署服务及配置管理apache+php-第二篇

实验目标

实现步骤

修改master的配置文件，指定base环境路径，base环境是必须指定的

创建目录

重启master

在base目录下面创建一个web目录用于存放web相关的sls文件

cd到bash/web目录里面创建apache.sls文件

执行状态模块部署服务

高级状态的使用 需要在master配置文件里面打开 state_top: top.sls并重启master

在bese环境目录下面添加top.sls

执行高级模块方法，高级方法到 base下面找top.sls 文件编排告诉每个minion需要干什么，一般生产环境用高级状态多些

上面我们使用了2个状态模块pkg和service，下面我们使用file文件配置模块

在base/web目录下面添加一个lamp.sls，一般在添加里面的内容之前需要在外面找一台服务器进行测试拿到准确的包信息后再进行配置

拷贝源文件到base/web目录下，这个根据自己的实际情况找源文件拷贝过来

执行状态模块部署服务

使用file模块下面的recurse方法进行apache的conf.d目录管理配置如下

创建salt源目录，并拷贝数据导源文件目录，数据文件来源根据自己业务的实际情况

验证目录管理是否生效

验证没有问题在node1和node2上面都执行

使用watch在apache配置文件发送变化时，重新加载apache配置

使用require可以让各ID之间产生依赖关系，避免无效执行

测试apache php环境工作是否正常,在2个节点上的apache工作目录下创建phpinfo文件

现在使用salt添加访问phpinfo需要账号密码

在lamp.sls 里面添加一个名为apache-auth 状态ID并使用require指定依赖关系

但是上面有些小问题

再次执行lamp.sls状态模块，就解决了上面的问题

base的目录结构如下

cat lamp.sls

至此apache和php测试已完成

这里补充一个file模块的append方法

执行状态模块，添加成功
