wget http://mirrors.kernel.org/centos/5.2/extras/i386/RPMS/qemu-0.9.0-4.i386.rpm
wget http://mirrors.kernel.org/centos/5.2/extras/i386/RPMS/kvm-36-1.i386.rpm
wget http://mirrors.kernel.org/centos/5.2/extras/i386/RPMS/kmod-kvm-36-2.2.6.18_92.1.10.el5.i686.rpm
wget http://mirrors.kernel.org/centos/5.2/updates/i386/RPMS/kernel-2.6.18-92.1.10.el5.i686.rpm
yum install qemu-0.9.0-4.i386.rpm kvm-36-1.i386.rpm kmod-kvm-36-2.2.6.18_92.1.10.el5.i686.rpm kernel-2.6.18-92.1.10.el5.i686.rpm
ln -s /usr/bin/qemu-kvm /usr/bin/kvm

到这一步，如果都没有出现error，那么重新启动虚拟机。

step 6. 启动mysql服务

/etc/init.d/mysqld start

设置mysql密码

mysqladmin password <password>

设置mysql服务在主机启动的时候自动启动

chkconfig mysqld on

以上6步，我们接着开始配置ECP.

step 7:

cd /opt/enomalism2 scripts/init-db.sh <mysql root password> <new ecp user> <new ecp password>

cp default.cfg config/$HOSTNAME.cfg

• Change sqlobject.dburi="mysql://enomalism2:zx45qw12@localhost/enomalism2" to reflect your proper MySQL username and password.
• Change enomalism2.self="5fe6f05e-7ee0-11dc-ba7c-0011d88b8e81" to reflect a unique identifier for your cluster environment (each instance needs to be unique)
  • Most distros have a utility such as uuid or uuidgen that can generate a number for you. The only valid value in this field is a uuid.
• Change enomalism2.baseurl="http://127.0.0.1:8080/rest/" to the IP/hostname you use to access the ECP web interface.
• Change enomalism2.ip_addr="1.2.3.4" to the IP/hostname you use to access the ECP web interface, this will be used later for clustering

验证并查看一下mysql里面存的元数据配置。

mysql> use enomalism2
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

接下来我们配置一下VNC，这一步如果不配置，后面在节目里面启动虚拟镜像的时候会提示连接不上虚拟镜像，也可以在遇到问题后在配置。这里我们先配置好。

• /etc/libvirt/qemu.conf (NOTE: If this file is missing or is a directory, you probably did not install the 0.4.1 version of libvirt!)

  # VNC is configured to listen on 127.0.0.1 by default.
  # To make it listen on all public interfaces, uncomment
  # this next option.
  #
  # NB, strong recommendation to enable TLS + x509 certificate
  # verification when allowing public access
  #
  vnc_listen = "0.0.0.0"

• /etc/xen/xend-config.sxp

  # The interface for VNC servers to listen on. Defaults
  # to 127.0.0.1  To restore old listen everywhere behaviour
  # set this to 0.0.0.0
  (vnc-listen 0.0.0.0)

到这里面，我们开始启动ECP，关键的一步。

/etc/init.d/enomalism2.sh start

Starting enomalism2
Setting up KVM/Qemu Networking
Configuring Virtual Bridge on eth0 IP x.x.x.x

ok，启动成功！

先看一下web页面，下一篇详细介绍功能使用。
