# 安装指定版本的Docker-CE:
# Step 1: 查找Docker-CE的版本:
# yum list docker-ce.x86_64 --showduplicates | sort -r
# Loading mirror speeds from cached hostfile
# Loaded plugins: branch, fastestmirror, langpacks
# docker-ce.x86_64 17.03.1.ce-1.el7.centos docker-ce-stable
# docker-ce.x86_64 17.03.1.ce-1.el7.centos @docker-ce-stable
# docker-ce.x86_64 17.03.0.ce-1.el7.centos docker-ce-stable
# Available Packages
# Step2 : 安装指定版本的Docker-CE: (VERSION 例如上面的 17.03.0.ce.1-1.el7.centos)
# sudo yum -y install docker-ce-[VERSION]
# 注意：在某些版本之后，docker-ce安装出现了其他依赖包，如果安装失败的话请关注错误信息。例如 docker-ce 17.03 之后，需要先安装 docker-ce-selinux。
# yum list docker-ce-selinux- --showduplicates | sort -r
# sudo yum -y install docker-ce-selinux-[VERSION]
# 通过经典网络、VPC网络内网安装时，用以下命令替换Step 2中的命令
# 经典网络：
# sudo yum-config-manager --add-repo http://mirrors.aliyuncs.com/docker-ce/linux/centos/docker-ce.repo
# VPC网络：
# sudo yum-config-manager --add-repo http://mirrors.could.aliyuncs.com/docker-ce/linux/centos/docker-ce.repo

关于博客程序更换的一点思考
最近把博客程序从Halo换到了WordPress，还记得第一次买学生机装的就是WordPress，还是逃不过真香定律啊，那时候觉得WordPress臃肿，而且设计的使用方式有点让我摸不着头脑，好多操作逻辑、操作流程不是很符合我的思考方式，现在觉得，是那时候是我见识的不够多。
古语有云：操千曲而后晓声，观千剑而后识器。直到现在，尝试过Hexo、Hugo、Jekyll、Typecho、ZBlog一众博客建站程序之后，突然觉得，WordPress才是最适合我的那一个。类似Hexo、Jekyll、Hugo这种静态博客在搭建上肯定要简单一些，部署方面可以选择GitHub、Gitee、Coding这种托管平台、不需要主机或者服务器的费用、但写完博客需要编译确实让我有点头疼、使用过Jekyll不需要部署的方案、使用的Hux大佬的主题、只需要简单的git push就好了，但是静态博客的评论也是一个问题，当然，也有会Disqus/Livere（来必力）/Valine、Gitment/Gitalk/utterances/Vssue等一众方案，但是我不是很喜欢这种嵌入式分离的结构，因为有的插件总是在主程序加载完成后再次渲染，就像代码的格式主题渲染一次后插件再次渲染，视觉上就是内容有替换的过程，WP也有这个问题。响应速度快是静态博客的一大优点，所以相对来说，Halo、WP、Zblog是比较慢一点的，当然只是相对来说。
博客文章内容的处理方式是我喜欢WP的另一个原因。不管是静态的Hexo、Jekyll，还是动态的Typecho、Halo，无一列外的选择了转化Markdown为HTML的方式展示文章，这就导致了我无法对图片进行很好的排版，WP的块编辑器很好的解决了这一问题。
删繁就简，回归本真。这次博客改版我去掉了上一版中很多内容，也是为了把中心放到文章内容上。归档页是很多博客的标配，但去掉了好像也真的无伤大雅，还有与之类似的标签页、分类页，当然看着满满的文章标题是很有成就感的，但这次我没有加归档页，而是考虑是否在侧边栏加入一个归档组件。相册页是很多博客都有的一个菜单，好的照片确实不错，但我好像没有什么拿得出手的照片，等有了再考虑这个吧。留言页，觉得这个大可不必，随便找一篇文章留言或者发邮件吧。日志或者说动态页，上一版Halo博客我用的很频繁，当作微信朋友圈或者QQ空间用了，简短的想法，又不至于发一篇文章，这个板块确实有其存在的意义，但我想放弃碎片化的输出，打算系统的整理自己的想法，互联网时代的垃圾内容已经够多了，我就尽量不再输出互联网垃圾了，再者说，人每天都会产生很多想法，但大多数没有实际意义，当然随时记录自己的想法是一个很好的习惯，但不必要发到这里，我还是选择其他方式。
WP的插件系统是很丰富的。装完之后我装了好几个插件：KaTeX，WP Fastest Cache、SyntaxHighlighter Evolved…不得不说这很方便，虽然我觉得使用插件丰富功能的方式比较排他，但这也是另一种组件化吧。就拿代码高亮插件来说，标记某一行或者某几行代码在静态博客是很难实现的一个功能，支持Latex也会使加载速度变慢，但WP插件很好的解决了这个问题。
对于主题来说，以前无尽的折腾主题，改颜色、改动画、各种魔改，而忘记了最重要的内容，我虽然知道这一点并努力避免，然而我依然不能很好的实践，这次我努力不陷入这个漩涡之中。这次没有黑暗模式，而且我突然觉得，黑色主题的时代虽然已经到来，但还不够成熟，我安装完博客看着文章的图片深思，诸如代码图片这种黑色格调的板块好像与博客格格不入、以前的Halo里面的主题也有这个问题，我曾想过深浅色模式使用不同的代码主题，但图片我怎么也不能很好的解决，虽然目前有一些处理方案，但我觉得可以等等。博客上传图片大小限制2M我决定保留，虽然有其他方案转换为webp格式，但转换也需要服务器资源啊。
有人穷途末路，夕阳西下，有人崭新起点，旭日东升。
Hello world!
Welcome to WordPress. This is your first post. Edit or delete it, then start writing!
MySQL数据库连接报错
解决方法
在数据库连接后面加
?useUnicode=true&useSSL=false&characterEncoding=utf-8&serverTimezone=Asia/Shanghai&useAffectedRows=true&allowMultiQueries=true
如果是xml文件，加
?useUnicode=true&useSSL=false&characterEncoding=utf-8&serverTimezone=Asia/Shanghai&useAffectedRows=true&allowMultiQueries=true

Sat Nov 12 21:09:13 CST 2022 WARN: Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.
