下面以Ubuntu 11.04.2服务器版为例，说明一下管理节点安装方法： 下载安装包： wget http://www./downloads/convirt/2.0.1/convirt-install-2.0.1.tar.gz
wget http://www./ConVirt/convirt-2.0.1-chinese.tar.gz 安装依赖关系： sudo apt-get install libmysqlclient-dev sudo apt-get install xen-utils-4.1
tar -xzf convirt-install-2.0.1.tar.gz
sudo ./convirt-install/install/cms/scripts/install_dependencies
修改MySQL配置，在/etc/mysql/my.cnf文件的[mysqld]部分添加如下内容： innodb_buffer_pool_size=1G
innodb_additional_mem_pool_size=20M
重新启动MySQL： sudo /etc/init.d/mysql restart
修改ConVirt数据库配置，编辑~/convirt/src/convirt/web/convirt/development.ini文件。
修改下面这行，将字符串'root:root'替换成你的数据库用户名和密码，然后保存。 sqlalchemy.url=mysql://root:root@localhost:3306/convirt?charset=utf8 安装ConVirt 2.0.1： source convirt-install/install/cms/scripts/install_config
tar -xzf ./convirt-2.0.1-chinese.tar.gz -C $CONVIRT_BASE
./convirt-install/install/cms/scripts/setup_tg2
./convirt-install/install/cms/scripts/setup_convirt 启动ConVirt服务：
cd ~/convirt
./convirt-ctl start 通过浏览器访问管理界面，缺省的用户名和密码都是admin。 http://ip-address:8081/ 在CentOS 5.4/5.5/5.6下的安装方法与上面的方法类似，忽略掉 sudo apt-get install libmysqlclient-dev 即可。 计算节点的安装配置以及更详细的使用文档，请参考Convirture的官方网站： http://www./wiki/index.php?title=Main_Page
convirt2.0的安装过程
获得 convirt2.0
wget –no-cache http://www./downloads/convirt/2.0.1/convirt-install-2.0.1.tar.gz
convirt-install-2.0.tar.gz是convirt的安装脚本，convirture组织在这个包里写了一个安装脚本来初始化系统环境变量，安装需要的各种组件，所以你一定要把保正你的convirt服务器能够正常Internet。 sudo apt-get update
[root@xencms ~]# tar -zxvf convirt-install-2.0.tar.gz 这是一个非常好的安装脚本实例，在这里先不分析各个function的调用，我想利用以后文章单独分析。
/root/convirt-install/install/cms/scripts
初始化系统环境
./install_dependencies
在初始化的过程中最重要的一项是mysql的设置
Enter current password for root (enter for none):
由于测试机之前没有安装mysqld服务，是由convirt-install中的脚本来完成的，所以初始密码为空。
Set root password? [Y/n] y
此处一定要设置mysql密码因为convirt初始化mysql时密码是写到程序中的,password要设置为”convirt”。
Running mysql_secure_installation.
Current root password for fresh installation is blank. So simple press enter.
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MySQL to secure it, we’ll need the current
password for the root user. If you’ve just installed MySQL, and
you haven’t set the root password yet, the password will be blank,
so you should just press enter here. Enter current password for root (enter for none):
OK, successfully used password, moving on… Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation. Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
… Success!
By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment. Remove anonymous users? [Y/n] y
… Success! Normally, root should only be allowed to connect from 'localhost’. This
ensures that someone cannot guess at the root password from the network. Disallow root login remotely? [Y/n] y
… Success! By default, MySQL comes with a database named 'test’ that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment. Remove test database and access to it? [Y/n] y
- Dropping test database…
… Success!
- Removing privileges on test database…
… Success! Reloading the privilege tables will ensure that all changes made so far
will take effect immediately. Reload privilege tables now? [Y/n] y
… Success! Cleaning up… All done! If you’ve completed all of the above steps, your MySQL
installation should now be secure. Thanks for using MySQL!
Stopping MySQL: [ OK ]
Starting MySQL: [ OK ]
Prerequsite for ConVirt Management Server (CMS) installed.
mysql初始化成功，
install_dependencies的整个初始化过程被我记录到了dependencies.log中，用于之后的分析。有兴趣可以下载后看一下。
安装 convrit软件 ./install_convirt
ConVirt Setup Done… cd /root/convirt
./convirt-ctl start convirt已经安装完成了，convirt日志，在这个过程中convirt会能过ssh-keygen 生成root用户的key文件，生成的这个key文件在以后的多服务器控制和VNC端口转发都会用到。
[root@xencms .ssh]# ls
cms_id_rsa cms_id_rsa.pub
[root@xencms .ssh]# pwd
/root/.ssh 启动convirt服务 cd /root/convirt
./convirt-ctl start
使用netstat -nl我们应该看到8081端口，如果服务不能正常启动，在/root/convirt目录下有两个日志文件
[root@xencms convirt]# cat convirt.log
[root@xencms convirt]# cat paster.log
convirt.log中记录的是convirt程序的运行日志
paster.log向是一个http的acsess日志，convirt使用的是tg2env做为http服务。 [root@xencms convirt]# netstat -nlp tcp 0 0 10.0.121.8:8081 0.0.0.0:* LISTEN 10053/python convirt安装完毕 访问http://IP:8081默认管理员admin密码admin
