08 saltstack生产实例-apahce+php+redis

1、apache+php

前几章的LAMP:https://www.cnblogs.com/venicid/p/11276232.html#_label2

Php放在apache

1、目录结构

2、php安装.sls，配置file

安装

[root@linux-node1 /srv/salt/prod/modules/apache]# cat php.sls 

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

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

配置文件

[root@linux-node1 /srv/salt/prod/modules/apache]# cp /etc/php.ini files/

3、apache安装.sls，配置file

安装

[root@linux-node1 /srv/salt/prod/modules/apache]# cat init.sls

include:
  - modules.apache.php

apache-install:
  pkg.installed:
    - name: httpd

apache-config:
  file.managed:
    - name: /etc/httpd/conf/httpd.conf
    - source: salt://modules/apache/files/httpd.conf
    - user: root
    - group: root
    - mode:
    - template: jinja
    - defaults:
      IPADDR: {{ grains['fqdn_ip4'][] }}
      PORT:
    - watch_in:
      - service: apache-service

apache-service:
  service.running:
    - name: httpd
    - enable: True
    - reload: True

配置文件

[root@linux-node1 files]# cp /etc/httpd/conf/httpd.conf .

[root@linux-node1 /srv/salt/prod/modules/apache]# vim files/httpd.conf

4、test

[root@# localhost ~]# salt 'linux-node1*' state.sls modules.apache.init saltenv=prod
[root@# localhost ~]# salt 'linux-node2*' state.sls modules.apache.init saltenv=prod

5、问题

问题描述：grains获取minion的ip地址时，获取失败。

解决：

saltstack master端grains.item fqdn_ip4 获取不到fqdn_ip4 值原因以及解决办法

关于hostname和fqdn的区别和获取及设置

最后：

　　重启master、minion

2、shop-user业务分离，管理apahce  php

产品线分级 shop

按业务分类：

功能模块写在modules，通用的

剩下的都是业务目录

不同的产品线对应不同的业务

1、目录结构

模块和业务目录

基本模块安装目录

业务对应的服务目录

2、php+apahce的基础安装配置

php基础安装.sls

[root@linux-node1 /srv/salt/prod/modules/apache]# cat php.sls
php-install:
  pkg.installed:
    - pkgs:
      - php
      - php-pdo
      - php-mysql

apache基础安装.sls，如上

[root@linux-node1 /srv/salt/prod/modules/apache]# cat init.sls
include:
  - modules.apache.php

apache-install:
  pkg.installed:
    - name: httpd

apache-config:
  file.managed:
    - name: /etc/httpd/conf/httpd.conf
    - source: salt://modules/apache/files/httpd.conf
    - user: root
    - group: root
    - mode:
    - template: jinja
    - defaults:
      IPADDR: {{ grains['fqdn_ip4'][] }}
      PORT:
    - watch_in:
      - service: apache-service

apache-service:
  service.running:
    - name: httpd
    - enable: True
    - reload: True

3、配置文件，修改如上

配置文件

[root@linux-node1 /srv/salt/prod/modules/apache]# cp /etc/php.ini files/

4、shop-user业务

业务对应的php+apahce的 sls文件

[root@linux-node1 /srv/salt/prod/shop-user]# cat web.sls
include:
  - modules.apache.init

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

web-config:
  file.managed:
    - name: /etc/httpd/conf.d/shop-user.conf
    - source: salt://shop-user/files/shop-user.conf
    - user: root
    - group: root
    - mode:
    - watch_in:
      - service: apache-service

File将要放在的位置

业务对应的配置文件

php.ini如上

shop-user.conf  待续................

3、php使用redis实现session 共享

https://www.cnblogs.com/youjiaxing/p/10407361.html

1、shop-user下的php.conf

用来进行session共享的

2、shop-user的apahce+php的sls

[root@linux-node1 /srv/salt/prod/shop-user]# cat web.sls
include:
  - modules.apache.init

php-config:　　      # php的conf
  file.managed:
    - name: /etc/php.ini
    - source: salt://shop-user/files/php.ini
    - user: root
    - group: root
    - mode: 

php-redis-config:     # session共享的
  file.managed:
    - name: /etc/httpd/conf.d/php.conf
    - source: salt://shop-user/files/php.conf
    - user: root
    - group: root
    - mode: 

web-config:           # apache的conf
  file.managed:
    - name: /etc/httpd/conf.d/shop-user.conf
    - source: salt://shop-user/files/shop-user.conf
    - user: root
    - group: root
    - mode:
    - watch_in:
      - service: apache-service

3、虚拟主机shop-user.conf

[root@linux-node1 /srv/salt/prod/shop-user]# cat files/shop-user.conf
<VirtualHost *:>
    ServerAdmin admin@example.com
    DocumentRoot /var/www/html
    ServerName demo.example.com
    ErrorLog "logs/demo-error.log"
    CustomLog "logs/demo-access.log" common
</VirtualHost>

4、修改apahce的8088端口

[root@linux-node1 /srv/salt/prod/modules/apache]# vim init.sls

5、启动

[root@linux-node1 /srv/salt/prod/shop-user]# salt \* state.sls shop-user.web saltenv=prod

容器，每个容器只跑一个虚拟主机

查看端口

6、配置php主页

node1，node2

[root@linux-node1 /srv/salt/prod/shop-user]# cd /var/www/html/
[root@linux-node1 /var/www/html]# cat info.php
<?php
phpinfo();
?>

访问主页

php和redis连上了

我的未连接到redis上面？？？

未开启redis主从模式吗？

7、添加到top.sls中

启动

[root@linux-node1 /srv/salt/base]# salt \* state.highstate
