CentOS VPS 建立 PPTP VPN 服务

发表于2013-05-19由jgh004

当前服务器环境: Centos 6

PPTP的配置主要有下面五个步骤：

验证内核是否加载了MPPE模块
安装所需的软件包
配置PPP和PPTP的配置文件
打开内核的IP转发功能
启动pptpd守护进程
配置iptables防火墙放行和转发规则

1、验证内核是否加载了MPPE模块：

modprobe ppp-compress-18 && echo MPPE is ok

1	modprobe ppp-compress-18 && echo MPPE is ok

2、安装所需的软件包：

安装前确保添加了 epel 源, 如果没有, 请参考 <<CentOS 添加常用 yum 源>>. 阅读全文

Linux vps 增加删除 swap 交换分区

发表于2013-05-19由jgh004

所有操作均需 root 权限

1.创建 swap 交换分区

首先用 fdisk -l 查看硬盘分区情况

fdisk -l

fdisk -l

Disk /dev/sda: 21.5 GB, 21474836480 bytes
255 heads, 63 sectors/track, 2610 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00097743

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1        2481    19922944   83  Linux

Disk /dev/sda: 21.5 GB, 21474836480 bytes

255 heads, 63 sectors/track, 2610 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Disk identifier: 0x00097743

Device Boot Start End Blocks Id System

/dev/sda1 * 1 2481 19922944 83 Linux

只有一个分区.

新建一个分区, 用于 swap 交换.

fdisk /dev/sda

1	fdisk /dev/sda

[root@itnmg ~]# fdisk /dev/sda

         switch off the mode (command 'c') and change display units to
         sectors (command 'u').

Command (m for help): m
Command action
   a   toggle a bootable flag
   b   edit bsd disklabel
   c   toggle the dos compatibility flag
   d   delete a partition  删除一个分区
   l   list known partition types
   m   print this menu     显示帮助菜单
   n   add a new partition  新建一个分区
   o   create a new empty DOS partition table
   p   print the partition table  显示分区表
   q   quit without saving changes  不保存退出
   s   create a new empty Sun disklabel
   t   change a partition's system id 改变分区类型
   u   change display/entry units
   v   verify the partition table
   w   write table to disk and exit 保存退出
   x   extra functionality (experts only)

Command (m for help):

[root@itnmg ~]# fdisk /dev/sda
