无法安装screen、iftop、nethogs的解决办法

由于Centos8yum源里没有epel，但是呢screen、iftop、nethogs是在epel里面的，解决方法如下：

yum -y install epel-release

执行命令，出现报错：Failed to set locale, defaulting to C.UTF-8

echo "export LC_ALL=en_US.UTF-8" >> /etc/profile
source /etc/profile

Failed to download metadata for repo 'AppStream'

cd /etc/yum.repos.d/
sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*
sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-* 
wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo
yum clean all
yum makecache

这个教程之前写过一次，后来不知道出于什么原因文章被删掉了，今天重写一下。

前提条件

1.设备已经越狱，不知道如何越狱请自行百度。本文只介绍AppSync安装教程。

教程开始

依赖加载

越狱完成以后，打开Cydia软件。

如图所示，Cydia会自动加载、安装所需的依赖，在这个过程中我们不要进行任何的操作。直到弹出刷新数据界面后，点击回到Cydia。

若提示软件包有必要更新，建议选择暂时忽略或更新必要软件包，我一般选择暂时忽略。

添加Cydia源

请访问查看此文章：如何将 “狗屎源” 添加到您的设备

安装AppSync

确定你已经正确添加源，源列表里面有你刚刚添加的源。

点击搜索，在输入框输入 appsync 稍等一会就会出现可用软件包。

选择好AppSync版本后，点击AppSync软件包，由于我已经安装了AppSync For iOS 6，我这里提示的是更改，你若是没安装提示的是安装，我们点击安装，在下一个界面点击继续。

至此，AppSync安装完成，安装完成以后请手动重启一下手机，确保AppSync插件生效。

安装AFC2.0

AFC2.0 全称 Apple File Conduit 2，在iOS7及以上的系统版本才需要安装，一般情况下iOS6无需安装。

安装Apple File Conduit 2需要使用91源，源地址：已失效，请使用 apt.gs

安装步骤请参阅上文的 安装AppSync。

错误排查

错误 · 提示缺少依赖

在安装AppSync时出现类似的缺少依赖的错误提示，导致无法继续下一步。

解决方法

教程第一步依赖加载未完成或完成的不彻底，请关掉Cydia后重新打开，让他重新加载。

若依旧加载失败，请更换网络(联通、电信、移动网络轮换着试试，推荐用联通网络)后，点击主页右边的重新加载重试。

功能演示

文件修改 headnav.php

文件路径：usr/themes/handsome/component/headnav.php

在此处：

    <!-- statitic info-->
    <?php
    if (@Utils::getExpertValue("show_static",true) !== false): ?>
    <ul class="nav navbar-nav hidden-sm">

        <!-- 在此追加代码 -->

        <li class="dropdown pos-stc">

追加内容(此处为追加后的代码)：

    <!-- statitic info-->
    <?php
    if (@Utils::getExpertValue("show_static",true) !== false): ?>
