convirt官网安装方法http://www.convirture.com/wiki/index.php?title=Convirt2_Installation#Firewall_setup_for_VNC

convirt工作原理：

Server端：

1.yum源更新

 cd /etc/yum.repos.d wget --no-cache http://www.convirture.com/repos/definitions/rhel/6.x/convirt.repo

2.socat安装

yum install socat

3.软件下载

 wget --no-cache http://www.convirture.com/downloads/convirt/2.5/convirt-install-2.5.tar.gz  wget --no-cache http://www.convirture.com/downloads/convirt/2.5/convirt-2.5.tar.gz  wget --no-cache http://www.convirture.com/downloads/convirture-tools/2.5/convirture-tools-2.5.tar.gz  4.软件安装  （1）tar -xzf convirt-install-2.5.tar.gz  cd convirt-install/install/cms/scripts/  （2）sudo ./install_dependencies   此时会检测mysql等相关依赖的东西，不要在安装有mysql的机器上安装server。同时，会提示输入  mysql的密码。  （3）主要安装配置convirt-install/install/cms/scripts/install_config，修改安装   路径，和软件包的版本号。    CONVIRT_BASE=/usr/local（默认安装是～，最后不需要重复加 /）    CONVIRT_DIR=$CONVIRT_BASE/convirt    VIRTUAL_ENV_NAME=tg2env    VIRTUAL_ENV_DIR=$CONVIRT_DIR/$VIRTUAL_ENV_NAME

    if [ "$SERVER" == "" ]; then      SERVER=www.convirture.com    fi    # convirt urls    CONVIRT_TARBALL=convirt-2.5.tar.gz（按照版本修改，否则可能会报错）    CONVIRT_DOWNLOAD_URL=http://${SERVER}/downloads/convirt/2.5/$CONVIRT_TARBALL  （4）source  install_config  （5）解压convirt包到安装目录：tar -xzf ./convirt-2.5.tar.gz -C $CONVIRT_BASE  （6）安装 TurboGears./convirt-install/install/cms/scripts/setup_tg2      在此阶段会报错，没有安装成功。因为需要在网络下载相应的包，可能会报错，因此多次执行此脚本      即可解决这个问题。  （7）修改src/convirt/web/convirt/development.ini 其中的mysql配置选项。   sqlalchemy.url=mysql://root:PASSWORD@localhost:3306/convirt?charset=utf8     密码为第二步的时候输入密码。  （8）./convirt-install/install/cms/scripts/setup_convirt（提示输入密码/密码为SSH服务器身份的CMS。  在setup_convirt过程中，会配置SSH密钥。正常配置即可，输入的密码在启动服务时需要输入。）  （9）启动server端：      前面创建的key拷贝过来，或者重新创建一个key    cp /var/lib/convirt/identity/cms_id_rsa* /root/.ssh/    chmod 600 /root/.ssh/cms_id_rsa    chmod 644 /root/.ssh/cms_id_rsa.pub     或ssh-keygen 重新创建    如果都没则提示    /root/.ssh/cms_id_rsa does not exist. Setting it to /root/.ssh/id_rsa.    /root/.ssh/id_rsa not found, Key based Authentication will not be used.      cd ~/convirt                   ./convirt-ctl start

 此时，server安装完成，localhost：8081访问即可，用户密码：admin，admin

 添加server的时候提示HostKeys object has no attribute has_key  解决方法

vim /data/convirt/src/convirt/core/utils/phelper.py  #修改两个地方然后重启@classmethod    def validate_host_key(cls, transport, hostname):        """        get the remote hosts key and validate against known host keys        throws exception with errno, reason        errno - reason        1  - Host not found        2. - Host found but key not found        3  - Authentication failed (wrong password?)        4  - Host found, key found, but keys do not match             (server changed/spoofed)        """        # check server's host key -- this is important.        key = transport.get_remote_server_key()        if not PHelper.host_keys.get(hostname):            print "Warning : Host not found ! ", hostname            #raise HostValidationException(1, "Host not found")        elif not PHelper.host_keys[hostname].get(key.get_name()):            print "Warning: Key not found ! ", hostname            #raise HostValidationException(2, "Key not found.")        elif PHelper.host_keys[hostname][key.get_name()] != key:            raise HostValidationException(3, "Keys mismatch for " + hostname)        return True

同时，连接client端必须要有server-client直接可以免密码登录
