ubuntu16.04上安装配置DHCP服务的详细过程

DHCP服务器是为客户端机器分配IP地址的,所有分配的IP地址都保存在DHCP服务器的数据库中.为了在子网中实现DHCP分配IP地址,需要在目标主机上安装配置DHCP服务. 安装DHCP服务 安装isc-dhcp-server: $ sudo apt install isc-dhcp-server 配置DHCP服务 首先需要知道目标主机的网卡名称: $ ifconfig 得到以下信息: eno1 Link encap:Ethernet HWaddr e8:39:35:46:10:f5 UP BR

Cent OS 6.X 上安装配置samba

一.基本简介 SMB(Server Messages Block,信息服务块)是一种在局域网上共享文件和打印机的一种通信协议,它为局域网内的不同计算机之间提供文件及打印机等资源的共享服务.SMB协议是客户机/服务器型协议,客户机通过该协议可以访问服务器上的共享文件系统.打印机及其他资源.通过设置"NetBIOS over TCP/IP"使得Samba不但能与局域网络主机分享资源,还能与全世界的电脑分享资源. 二.SMB的由来 在早期网络世界当中,档案数据在不同主机之间的传输大多是使用

在CentOS 6.4上安装配置GlusterFS

背景介绍: 项目目前在文件同步方面采用的是rsync,在尝试用分布式文件系统替换的时候,使用过MooseFS,效果差强人意,在了解到了GlusterFS之 后,决定尝试一下,因为它跟MooseFS相比,感觉部署上更加简单一些,同时没有元数据服务器的特点使其没有单点故障的存在,感觉非常不错. 环境介绍: OS: CentOS 6.4 x86_64 Minimal Servers: sc2-log1,sc2-log2,sc2-log3,sc2-log4 Client: sc2-ads15 具体步骤:
