    首先在CentOS/RHEL系统上安装wget才能用于下载，运行以下命令：

        sudo dnf -y install wget

    现在使用wget命令下载最新版本的Google Chrome：

        wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm

    导航到包含下载包的目录并执行以下命令：

        $ sudo dnf localinstall google-chrome-stable_current_x86_64.rpm -y

    执行结果如下图：

    打开Chrome浏览器的快捷方式文件

        $ vi /usr/share/applications/google-chrome.desktop
    修改 Exec=/usr/bin/google-chrome-stable %U 在其后面加上 --no-sandbox
