chef-infra - Chef-solo乱序安装MySql和Apache2

Question

我正在与 chef 和 vagrant 合作，以更好地自动化一些机器构建过程，但我遇到了一个我似乎无法弄清楚的问题。问题是，无论我们做什么，只要我们包含我们的 php 服务器说明书，它就会以某种方式将 apache2 弹出到运行列表的顶部。 mysql也是一样。我们想使用 remi repos，而不是被 PHP 5.3.3 困住，但我不能，因为 apache 和 mysql 首先安装。 IE，预期的安装顺序是这样的:

1. 运行 yum/apt update 并安装基线包(
2. baseline-linux-server recipes) 安装 apache2/php 安装 mysql
3. 服务器

但是我看到了:

1. 安装apache2
2. 安装mysql服务器
3. 开始按预期顺序安装所有内容——包括再次查看 php/apache2/mysql 服务器。

vagrantfile 中的运行列表如下所示:

chef.add_recipe "company-baseline-linux-server::enterprise-linux"
chef.add_recipe "company-baseline-linux-server"
chef.add_recipe "company-php-server"
chef.add_recipe "company-mysql-server"
chef.add_recipe "company-php-server::setup-website"
chef.add_recipe "company-wordpress-app"
chef.add_recipe "company-wordpress-app::copy-assets"
chef.add_recipe "company-wordpress-app::load-wordpress-db"

company-php::default 配方是:

#set apache ports
node.default['apache']['listen_ports'] = node['listen_ports']

#setup apache default modules
node.default['apache']['default_modules'] = %w(status alias rewrite headers deflate dir env mod_proxy mod_proxy_http mime negotiation setenvif authz_default authz_host log_config logio)
include_recipe "apache2"
include_recipe "apache2::mod_ssl"

#set apache to autostart
execute "auto start apache" do
    command "chkconfig httpd on"
end

#add php
include_recipe "php"
include_recipe "apache2::mod_php5"
include_recipe "php::module_mysql"

#disable iptables for now
include_recipe "iptables::disabled"

#kill default site
apache_site "default" do
  enable false
end

company-mysql::default 配方是:

node.default["mysql"]["remove_anonymous_users"] = true

include_recipe "mysql::server"

#setup remote database user
include_recipe "database"
include_recipe "database::mysql"

mysql_connection_info = {
  :host     => node['dbserver'],
  :username => 'root',
  :port     => node['mysql']['port'],
  :password => node['mysql']['server_root_password']
}

dbuser = node['remote_root_user']
dbpassword = node['remote_root_password']

mysql_database_user dbuser do
  connection    mysql_connection_info
  password      dbpassword
  host          '%'
  grant_option  true
  action        :grant
  only_if { node['remote_root_user'] }
end

mysql_database_user dbuser do
  connection    mysql_connection_info
  password      dbpassword
  host          'localhost'
  grant_option  true
  action        :grant
  only_if { node['remote_root_user'] }
end

当我运行所有这些时，我得到以下输出，其中可以看到首先安装 httpd，然后是 mysql，然后是从 EPEL 安装开始的 baseline-linux-cookbooks:

我已经尝试了大多数明显的技巧，例如将对此的调用直接推送到我们的 wordpress-app 配方中，并将运行列表声明为 run_list 而不是一堆包含。我怀疑这是简单而愚蠢的事情，但我似乎无法得出答案。

Answer 1

我对 Chef 的了解有限(阅读:几乎没有)，所以我看不到您的问题。但是，如果您还没有尝试过，我会提出一些建议:

• 查找可能导致异常的任何 override 或 force-override 属性类型。

• 在任何 metadata.rb 文件中寻找 depends apache2。

• 就像编写代码一样，逐步构建您的 Vagrantfile 并查看导致问题的第一件事，以尝试定位您的问题。

祝你好运!
