概述
2019年的时候，写了一篇博客来记录博客历史的迁移记录，这两年又经过工作变化、硬盘损坏，博客也是几经变迁。
尝试了基于Go的hugo框架，总体美观度和Hexo还是没法比，因此还是切换回了Hexo，换用了默认的landscape主题，重心放到有效的内容的记录上。评论系统还是采用valine，而在landscape下，设置valine还比Next复杂一些，我从这里 看到除了配置landscape项目，还需要在ejs文件里面设置，这里记录下。
详细流程
修改主题config 文件 HEXO_ROOT/themes/landscape/_config.yml, 添加下面内容:
# valine comment system. https://valine.js.org
valine:
enable: true # if you want use valine,please set this value is true
appid: wwwwweirowjreojwreoz # leancloud application app id
appkey: weiojwoerjoerj# leancloud application app key
notify: false # valine mail notify (true/false) https://github.com/xCss/Valine/wiki
verify: false # valine verify code (true/false)
pageSize: 10 # comment list page size
avatar: mm # gravatar style https://valine.js.org/#/avatar
lang: zh-cn # i18n: zh-cn/en
placeholder: 欢迎留言交流~~ # valine comment input placeholder(like: Please leave your footprints )
guest_info: nick,mail,link #valine comment header infoappid 和 appkey 从 leancloud 网站获取.
修改ejs文件HEXO_ROOT/themes/landscape/layout/_partial/after-footer.ejs，添加下面内容：
<% if(theme.valine.enable && theme.valine.appid && theme.valine.appkey){ %>
<script src="//cdn1.lncld.net/static/js/3.0.4/av-min.js"></script>
<script src="//unpkg.com/valine/dist/Valine.min.js"></script>
<script>
var GUEST_INFO = ['nick','mail','link'];
var guest_info = '<%= theme.valine.guest_info %>'.split(',').filter(function(item){
return GUEST_INFO.indexOf(item) > -1
});
var notify = '<%= theme.valine.notify %>' == true;
var verify = '<%= theme.valine.verify %>' == true;
new Valine({
el: '.vcomment',
notify: notify,
verify: verify,
appId: "<%= theme.valine.appid %>",
appKey: "<%= theme.valine.appkey %>",
placeholder: "<%= theme.valine.placeholder %>",
pageSize: '<%= theme.valine.pageSize %>',
avatar: '<%= theme.valine.avatar %>',
lang: '<%= theme.valine.lang %>',
visitor: 'true'
});
</script>
<% } %>修改HEXO_ROOT/themes/landscape/layout/_partial/article.ejs 文件，最后添加下面内容：
<% if (!index && post.comments && theme.valine.enable && theme.valine.appid && theme.valine.appkey){ %>
<section id="comments" class="vcomment">
</section>
<% } %>
