解决方案

XrayR安装时，系统没有unzip工具，也是会安装失败的，因为Centos7已经停止维护了，得换个数据源。

vi /etc/yum.repos.d/CentOS-Base.repo

把下面的配置文件，替换掉源文件。

[base]
name=CentOS-7 - Base
baseurl=http://vault.centos.org/7.9.2009/os/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7[updates]
name=CentOS-7 - Updates
baseurl=http://vault.centos.org/7.9.2009/updates/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7[extras]
name=CentOS-7 - Extras
baseurl=http://vault.centos.org/7.9.2009/extras/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

保存退出后，再执行：

yum clean all
yum makecache
yum install unzip -y

下面所有命令都用 root 直接复制粘贴即可：

cat >/etc/yum.repos.d/CentOS-Base.repo <<'EOF'
[base]
name=CentOS-7 - Base
baseurl=http://vault.centos.org/7.9.2009/os/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7[updates]
name=CentOS-7 - Updates
baseurl=http://vault.centos.org/7.9.2009/updates/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7[extras]
name=CentOS-7 - Extras
baseurl=http://vault.centos.org/7.9.2009/extras/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
EOFyum clean all
yum makecache
# 把缺的工具一次性补上
yum -y install wget curl unzip tar

删除残缺目录，重新跑官方一键脚本：

rm -rf /usr/local/XrayR
bash <(curl -Ls https://raw.githubusercontent.com/XrayR-project/XrayR-release/master/install.sh)

OK完成。
