convirt简介
convirt2.0是一款使用python和jquery结合编写的其于web的集中管理xen服务的程序。该程序在xen 社区项目，管理项目中被使用的量很高，convirt开发有开源版本与企业版本，企业版拥有服务支持，并增强了xen动态资源调整的功能，此次介绍的的为 convirt2.0开源版。
convirture tm有自己的wiki和论谈，相关问题可以查看与询问

convirt2.0的安装过程
获得 convirt2.0
wget –no-cache http://www.convirture.com/downloads/convirt/2.0/convirt-install-2.0.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。
[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
看一下我们正在使用中的界面，如下图：
管理其他的xen-server ，添加server 需要输入root密码和使用sshkey来进行添加，之后提示添加成功，没次重启xen-server的时候在convirt管理平台都会提示一个错误 Exception: remote_exec_cmd :Could not create channel，连不上xen-server服务器，这是需要注意的是，要在convirt管理平台上重启这个管理平台即可。
