在 CentOS 系统安装过程中配置网络连接 (图解)

Kevin 教程 1,128 次浏览 40条评论

使用 CentOS 光盘镜像安装系统需要自行配置网络,不然安装后没办法 SSH 连接。虽然可以用 VNC 之类控制面板登录配置,但由于不能复制粘贴,操作起来比较麻烦,还是安装过程中顺便配上好些。

CentOS 7

在安装选项界面点击“网络和主机名”,选中网卡设备点击“配置”,弹出窗口中点击“IPv4 设置”,切换到“手动”模式(有的主机商支持 DHCP 自动获取 IP),点击“Add”输入 IP 地址、子网掩码、网关地址(由主机商提供。若配置内网连接,则不用填网关),设置 DNS 服务器(多个用英文逗号分隔),保存设置后回到图二界面,滑动开关选项以连接网络。

其它网络选项通常保持默认,下面那个“需要 IPv4 地址完成这个连接”选项,其意思是当连接到兼容 IPv6 的网络时,如果 IPv4 配置失败而 IPv6 配置成功,则允许连接完成。

菜单栏最后的 IPv6 设置可以选择 DHCP 或忽略。

CentOS 6

在设置主机名界面下方点击“配置网络”,选中网卡点击“编辑”,勾选“自动连接”,切换“手动”模式,点击“添加”输入IP 地址、子网掩码、网关地址,设置 DNS 服务器。保存设置后会自动尝试连接,如果有错误会提示。
