|
||
<ol>
|
||
<li>nagios 需要安装主程序和 nrpe（nagios 和各被监控主机都必须安装）。如需使用自研前端可通过安装 ndoutils (用于把 nagios 监控信息写入数据库) 和 mysql 实现。具体安装见<span class="exturl" data-url="aHR0cHM6Ly9zdXBwb3J0Lm5hZ2lvcy5jb20va2Iv">官网</span></li>
|
||
<li>nagios 默认监控命令脚本放置在 libexec 中，自定义脚本也放到此处</li>
|
||
<li>etc/objects/commands.cfg 用于保存 nagios 默认监控命令</li>
|
||
<li>etc/nrpe.cfg 文件中需要添加用于被监控执行命令项（各被监控主机中都需要添加）<br />
|
||
<img data-src="https://file.jingxiyuan.cn/images/2022/10/18/image.png" alt="" /></li>
|
||
<li>etc/objects/hosts 目录下配置需要被监控的主机信息<br />
|
||
<img data-src="https://file.jingxiyuan.cn/images/2022/10/18/image2.png" alt="" /></li>
|
||
<li>etc/objects/servers 目录下配置需要在被监控主机上执行的监控命令（第 4 项中的命令）<br />

<li>被监控端需要把监控端的命令写入到 nrpe 的配置文件中</li>

<li>被监控端需要把命令执行脚本放入 libexec 目录中</li>
|

<li>被监控端自动安装脚本（可借鉴）</li>
|

</ol>
|
||
<pre><code class="language-bash">1、请先修改脚本中的服务端IP。
|
||
2、如被监控端不支持let计算命令请执行sudo dpkg-reconfigure dash命令，弹出选择窗口后选择no。
|
||
3、需要在脚本同目录下创建CentOS、Ubuntu、sh和conf目录，目录下分别放置nrpe的tar安装包、监控脚本和nrpe配置文件。

|

<pre><code class="language-conf">客户端的输出缓冲区的限制，因为某种原因客户端从服务器读取数据的速度不够快，可用于强制断开连接（一个常见的原因是一个发布 / 订阅客户端消费消息的速度无法赶上生产它们的速度）。
|
||
可以三种不同客户端的方式进行设置：
|
||
normal -&gt; 正常客户端
|
||
slave -&gt; slave 和 MONITOR 客户端
|
||
pubsub -&gt; 至少订阅了一个 pubsub channel 或 pattern 的客户端
|
||
语法 :
|
||
client-output-buffer-limit &lt;class&gt;&lt;hard limit&gt; &lt;soft limit&gt; &lt;soft seconds&gt;
|
||
一旦达到硬限制客户端会立即断开，或者达到软限制并保持达成的指定秒数（连续）。
|
||
例如，如果硬限制为 32 兆字节和软限制为 16 兆字节 /10 秒，客户端将会立即断开。如果输出缓冲区的大小达到 32 兆字节，客户端达到 16 兆字节和连续超过了限制 10 秒，也将断开连接。默认 normal 客户端不做限制，因为他们在一个请求后未要求时（以推的方式）不接收数据，
|
||
只有异步客户端可能会出现请求数据的速度比它可以读取的速度快的场景。
|
||
把硬限制和软限制都设置为 0 来禁用该特性
|
||
client-output-buffer-limit normal 0 0 0

默认配置如下：
|
||
save 900 1 #900秒内有1次更新就持久化
|
||
save 300 10 #300秒内有10次更新就持久化
|
||
save 60 10000 #60秒内有10000次更新就持久化
|
||
---关闭RDB持久化---
|
||
主从同步支持两种策略，即disk和socket方式。
|
||
新的slave端和重连的salve端不允许去继续同步进程，这被称之为“完全同步”。
|
||
一个RDB文件从master端传到slave端，分为两种情况：
|
||
1、支持disk：master端将RDB file写到disk，稍后再传送到slave端；
|
||
2、无磁盘diskless：master端直接将RDB file传到slave socket，不需要与disk进行交互。无磁盘diskless方式适合磁盘读写速度慢但网络带宽非常高的环境。
|
||
repl-diskless-sync no 默认不使用diskless同步方式
|
||
repl-diskless-sync-delay 30 无磁盘diskless方式在进行数据传递之前会有一个时间的延迟，以便slave端能够进行到待传送的目标队列中，这个时间默认是5秒
|
||
repl-ping-slave-period 60 slave端向server端发送pings的时间区间设置，默认为10秒
|
||
repl-timeout 3600 设置超时时间
|
||
repl-disable-tcp-nodelay no 是否启用TCP_NODELAY，如果启用则会使用少量的TCP包和带宽去进行数据传输到slave端，当然速度会比较慢；如果不启用则传输速度比较快，但是会占用比较多的带宽。
|
||
repl-backlog-size 1mb 设置backlog的大小，backlog是一个缓冲区，在slave端失连时存放要同步到slave的数据，因此当一个slave要重连时，经常是不需要完全同步的，执行局部同步就足够了。
|
||
backlog设置的越大，slave可以失连的时间就越长。
|
||
repl-backlog-ttl 3600 如果一段时间后没有slave连接到master，则backlog size的内存将会被释放。如果值为0则表示永远不释放这部份内存。
|
||
slave-priority 100 slave端的优先级设置，值是一个整数，数字越小表示优先级越高。当master故障时将会按照优先级来选择slave端进行恢复，如果值设置为0，则表示该slave永远不会被选择。
|
||
min-slaves-to-write 3
|
||
min-slaves-max-lag 10 设置当一个master端的可用slave少于N个，延迟时间大于M秒时，不接收写操作。

<description><![CDATA[ <h4 id="前期准备"><a class="anchor" href="#前期准备">#</a> 前期准备</h4>
|
||
<p> 首先安装好 svn 和 git 工具。</p>
|
||
<h4 id="svn转git"><a class="anchor" href="#svn转git">#</a> svn 转 git</h4>
|
||
<p>1、 到 svn 项目目录右键选中 gitbash 打开窗口，执行获取用户并映射成 git 样式账号命令如下：</p>
|
||
<pre><code class="language-bash">svn log -q | awk -F '|' '/^r/ &#123;sub(&quot;^ &quot;, &quot;&quot;, $2); sub(&quot; $&quot;, &quot;&quot;, $2); print $2&quot; = &quot;$2&quot; &lt;&quot;$2&quot;&gt;&quot;&#125;' | sort -u &gt; users.txt
|
||
</code></pre>
|
||
<p> 然后会在目录下生成文件 users.txt 样式如：zhansan = 张三 <span class="exturl" data-url="bWFpbHRvOnpoYW5zYW5AeHh4LmNvbQ==">zhansan@xxx.com</span>。</p>
|
||
<p>2、新建个文件夹，将生成的 users.txt 放入新建的文件夹，然后在新建的文件夹中右键选中 gitbash 弹出窗口后执行下面命令（https://svn_project_url/ 为 svn 库的 url），拉取 svn 代码到本地新建文件夹中。</p>
|
||
<pre><code class="language-bash">git svn clone https://svn_project_url/ --no-metadata --no-minimize-url --authors-file=users.txt
|
||
</code></pre>
|
||
<p> 期间可能会弹出 svn 的账户密码验证窗口，正确输入即可。</p>
|
||
<h4 id="推送项目到git库"><a class="anchor" href="#推送项目到git库">#</a> 推送项目到 git 库</h4>
|
||
<p>1、在 gitbash 窗口 cd 到 git 项目文件夹中执行以下命令把 git 仓库地址加入到 remote 中（https://git_project_url/ 为 git 库的 url）。</p>
|
||
<pre><code class="language-bash">git remote add origin https://git_project_url/
|
||
</code></pre>
|
||
<p>2、push 项目到 git 库中。</p>
|
||
<pre><code class="language-bash">git push origin master
|
||
</code></pre>

<description><![CDATA[ <h4 id="x-frame-options响应头配置详解"><a class="anchor" href="#x-frame-options响应头配置详解">#</a> X-Frame-Options 响应头配置详解</h4>
|
||
<p> X-Frame-Options HTTP 响应头是用来给浏览器指示允许一个页面可否在，或者 中展现的标记。网站可以使用此功能，来确保自己网站的内容没有被嵌套到别人的网站中去，也从而避免了点击劫持 (clickjacking) 的攻击。<br />
|
||
X-Frame-Options 三个参数:</p>
|
||
<p>1、 DENY</p>
|
||
<p> 表示该页面不允许在 frame 中展示，即便是在相同域名的页面中嵌套也不允许。</p>
|
||
<p>2、SAMEORIGIN</p>
|
||
<p> 表示该页面可以在相同域名页面的 frame 中展示。</p>
|
||
<p>3、ALLOW-FROM uri</p>
|
||
<p> 表示该页面可以在指定来源的 frame 中展示。</p>
|
||
<p>4、ALLOWALL</p>
|
||
<p> 表示该页面可以在任何来源的 frame 中展示。</p>
|
||
<p> 换一句话说，如果设置为 DENY，不光在别人的网站 frame 嵌入时会无法加载，在同域名页面中同样会无法加载。另一方面，如果设置为 SAMEORIGIN，那么页面就可以在同域名页面的 frame 中嵌套。正常情况下我们通常使用 SAMEORIGIN 参数。</p>
|
||
<h4 id="apache配置"><a class="anchor" href="#apache配置">#</a> Apache 配置</h4>
|
||
<p> 需要把下面这行添加到'site' 的配置中</p>
|
||
<pre><code class="language-shell"> Header always append X-Frame-Options SAMEORIGIN
|
||
</code></pre>
|
||
<h4 id="nginx配置"><a class="anchor" href="#nginx配置">#</a> Nginx 配置</h4>
|
||
<p> 需要添加到 ‘http’, ‘server’ 或者 ‘location’ 的配置项中，个人来讲喜欢配置在‘server’ 中</p>
|
||
<p> 正常情况下都是使用 SAMEORIGIN 参数，允许同域嵌套</p>
|
||
<pre><code class="language-shell"> add_header X-Frame-Options SAMEORIGIN;
|
||
</code></pre>
|
||
<p> 允许单个域名 iframe 嵌套</p>
|
||
<pre><code class="language-shell"> add_header X-Frame-Options ALLOW-FROM http://xxx.com/;
|
||
</code></pre>
|
||
<p> 允许多个域名 iframe 嵌套，注意这里是用逗号分隔</p>
|
||
<pre><code class="language-shell"> add_header X-Frame-Options &quot;ALLOW-FROM http://xxx.com/,https://xxx.com/&quot;;
|
||
</code></pre>
|
||
<p> 允许任何域名 iframe 嵌套</p>
|
||
<pre><code class="language-shell"> add_header X-Frame-Options ALLOWALL;

<description><![CDATA[ <p><em> 今天突然发现博客的音乐无法播放了。经过一顿查找，发现是因为 https://api.i-meto.com/meting/api 调用出错了。shoka 主题应该是通过这个网站提取音乐地址、图片等信息。通过断点发现网易播放列表还是能正常获取的，只是列表中的具体音乐、图片无法获取了。于是自己用获取的列表信息组装出正确的 url 问题基本解决。只针对网易播放列表，图片只能使用一张固定的。</em></p>
|
||
<p><em> 解决方法如下：</em></p>
|
||
<p><em> 到 themes\shoka\source\js_app 目录下打开 player.js 文件，在最底部 init (config) 下加入 vendorJs ('fancybox');，然后找到 56 行用下面的代码替换即可。</em></p>

<description><![CDATA[ <p> <em>今天前端开发跟我反馈用 vue 的 socketio 连接不上后台服务，连接无反应无任何报错。所以不清楚是前端代码问题还是后台服务的问题。由于框架为另一同事搭建，我只负责处理后端业务逻辑部分，所以第一时间我也不清楚具体的原因。于是我找了个第三方的 socket 工具尝试连接，果然有问题。但是只是提示连接不上，无明显错误原因。到后台查看发现有提示 Unknown transport for request 错误，最后通过调试发现 netty-socketio 的库中 AuthorizeHandler 类有段处理 transport 的代码只能接受大写的 WEBSOCKET 或者 POLLING，于是我在工具中按要求填上结果还是不行。然后我在网上搜索也未发现有相关问题，只发现有网友提示需要用 socketio 的库，不要自己写 socket 连接。于是我找了 socket.io.js 来连接，结果还是一样。经过大量调试改代码，最后突发奇想，有没有可能跟 netty-socketio 的版本有关系，于是我把版本从 1.7.20 升级到 1.7.21，结果就奇迹般的好了。</em></p>
