在Puppet中用ERB模板来自动配置Nginx虚拟主机

模板文件是在puppet模块下面templates目录中以”.erb”结尾的文件，puppet模板主要用于文件，例如各种服务的配置文件，相同的服务，不同的配置就可以考虑使用模板文件，例如Nginx和Apache 的虚拟主机配置就可以考虑采用ERB模板，nginx的安装在这里建议用系统内部自带的YUM源来安装或其它第三方YUM源来安装，如果是用Nginx的官方源来安装nginx的话，我们可以查看下/etc/yum.repos.d files |      |-- manifests |      |  `-- init.pp |      `-- templates |          |-- nginx.conf.erb ,owner => root,group => root, path => "/etc/nginx/nginx.conf", content=> template("nginx/nginx.conf.erb     file{ "/etc/nginx/conf.d/${sitedomain}.conf":         content => template("nginx/nginx_vhost.conf.erb

Rails布局和视图渲染

= Book.all end end 基于“多约定，少配置”原则，在 index 动作末尾并没有指定要渲染的视图，Rails会自动在控制器的视图文件夹中寻找 action_name.html.erb " render action: "edit.html.erb" render "books/edit" render "books/edit.html.erb" render template: "books 如果没有 .erb 布局，Rails会使用 .builder 布局。 布局渲染局部视图 _link_area.html.erb ，此时局部布局与局部视图保存在同一个文件夹中。 new.html.erb

New zone

如果程序中重复代码达到一定量级，会影响可读性和可维护性，这时我们可以将其中重复部分抽出来，单独成块 [root@h202 blog]# vim app/views/comments/_comment.html.erb [root@h202 blog]# cat app/views/comments/_comment.html.erb

Commenter: Comment: <%= comment.body %>

Title: <%= @article.title

FMEN | NTIRE2021-ESR最低内存占用超分方案

此外，作者在EISR常用的残差模块基础上提出了ERB(Enhanced Residual Block)以加速模型推理速度。 组合上述设计理念记得到了本文所提FMEN与FMEN-S。 为解决上述问题，基于序贯式结构，本文提出ERB与HFAB分别用于深层特征学习与特征增强，不仅可降低内存占用，同时可加速推理效率。 2Experiments 上图对比了基于ResBlock、PlainBlock以及ERB的EDSR与FMEN性能，可以看到：相比ResBlock，ERB具有与其相当的性能，而PlainBloc则出现了严重性能下降 而在推理阶段，ERB可以折叠而PlainBlock形式并享受其高推理效率特征。 上表对比了ResBlock与ERB在不同超分模型的推理效率对比，可以看到：相比ResBlock，ERB模块的推理效率平均快10%左右。
