Centos 安装 & cleversafe的使用

北大方法：

yum groupinstall “Development Tools”
yum -y install hmaccalc ncurses-devel unifdef zlib zlib_devel openssl openssl-devel libX11-devel

glibc-devel python-devel bridge-utils  libtool-ltdl

cd <XenSrcDir>
make xen tools

cd <KernelSrcDir>
cp configs/kernel-2.6.18-x86_64-xen.config .config
make

cd <XenSrcDir>
make install-xen install-tools

cd <KernelSrcDir>
make modules_install install
mkinitrd /boot/initrd-2.6.18-prep.img 2.6.18-prep

源设置

cd /etc/yum.repos.d/

mv CentOS-Base.repo CentOS-Base.repo.bak1

wget http://centos.ustc.edu.cn/CentOS-Base.repo
yum install hmaccalc ncurses-devel zlib-devel openssl-devel python-devel bridge-utils libtool-ltdl iasl xorg-x11-drv-evdev xorg-x11-drv-fbdev xorg-x11-drv-i810-devel xorg-x11-drv-via-devel xorg-x11-proto-devel xorg-x11-server-sdk xorg-x11-xtrans-develevel xorg-x11-drv-via-devel xorg-x11-proto-devel xorg-x11-server-sdk xorg-x11-xtrans-devel texinfo-tex Texinfo

yum install hmaccalc ncurses-devel zlib-devel openssl-devel python-devel bridge-utils libtool-ltdl iasl xorg-x11-drv-evdev xorg-x11-drv-fbdev xorg-x11-drv-i810-devel xorg-x11-drv-via-devel xorg-x11-proto-devel xorg-x11-server-sdk xorg-x11-xtrans-devel

下载mercurial-1.4.1 包

make all

make install

有doc出错，没管它。

export PYTHONPATH=/usr/local/lib/python2.4/site-packages

cp contrib/sample.hgrc /root/.hgrc

cleversafe的使用

/root/dsnet-accesser/bin

创建一个vault:

./dsnet-create-vault --name="iqn.2010-05.anycn" --descriptor="../conf/anycn.xml"

一个典型的 xml配置文件是：

这个是本地测试用的。

[root@localhost bin]# ./dsnet-create-target --name="iqn.2010-05.anycn" --iqn="iqn.2010-05.anycn"
Successfully created iSCSI target using dsNet vault.
Target name: iqn.2010-05.anycn
Vault name: iqn.2010-05.anycn
Vault identifier: 5be8674c-8a9d-4735-8f09-dbc8db7a7a1b
Target is now running.

yum install XX

service iscsi start

本地的iscsi访问：

[root@localhost bin]# iscsiadm -m discovery -t sendtargets -p 127.0.0.1
127.0.0.1:3260,1 iqn.2010-05.anycn
127.0.0.1:3260,1 iqn.2010-03.sjtu
发现了新的 127.0.0.1:3260,1 iqn.2010-05.anycn

login ：

iscsiadm -m node --targetname iqn.2010-03.anycn -p 127.0.0.1 --login

ls /dev/sd*

可以发现新增的硬盘。

mount 一下就能访问了。
