OpenStack 问题汇总,错误解决

近日在学习OpenStack,使用时遇到些问题,故记录下。

安装的为官网目前最新版Liberty,我一开始下载安装的是早期版本(Earliest Version),发现有Dashboard登陆不进的情况,而且装了两台机都是一样的情况,登陆界面一直报“Unable to retrieve authorized projects.”错误,尝试许多方法都无效;故之后换最新版本(Most Recent Version),使用同样的安装配置却无此问题。

其它问题:

  1. 创建云主机时报错,提示Unexpected API Error,如图
    Error1
    查看nova-api日记录:

    看样子是API出错,经多方查找,后与官方手册对比后发现是nova.conf配置文件中以下几项出现问题,起初我是直接注释去掉的,没有注意,更改完重新nova所有服务后无此错误:

    [[email protected] ~]# vim /etc/nova/nova.conf
    [DEFAULT]
    ...
    network_api_class = nova.network.neutronv2.api.API
    linuxnet_interface_driver = nova.network.linux_net.NeutronLinuxBridgeInterfaceDriver
    security_group_api = neutron
    firewall_driver = nova.virt.firewall.NoopFirewallDriver
  2. 启动云主机时提示[错误: No valid host was found. There are not enough hosts available.],如图
    Error2
    提示没有有效的计算主机,云主机创建错误。这种情况先想到宿主机剩余资源是否够用,经查看足够使用。
    然后查看指导服务日志:

    两者均提示网络绑定出现问题,让查看neutron日志:

    提示为ml2插件绑定时出错,疑与neutron-linuxbridge-agent服务有关,服务使用脚本启动的,显示正常。于是使用命令重新启动服务后发现问题:

    [[email protected] ~]# neutron-linuxbridge-agent --config-file=/etc/neutron/neutron.conf --config-file=/etc/neutron/neutron/plugins/ml2/ml2_conf.ini --config-file=/etc/neutron/neutron/plugins/ml2/linuxbridge_agent.ini > /dev/null 2>&1 &

    发现进程很快就自已结束掉了,查看日志:

    neutron我设置为使用ml2插件,网络类型为flat,使用linuxbridge桥接。这下很明显了,提示Tunnel创建失败,没有配置local_ip。于是检查linuxbridge_agent.ini配置文件:

    [[email protected] ~]# vim /etc/neutron/neutron/plugins/ml2/linuxbridge_agent.ini
    ...
    # (StrOpt) Local IP address to use for VXLAN endpoints (required)
    local_ip = 172.16.200.5

    将其添加上后服务便启动正常

    [[email protected] ~]# ps -aux | grep neutron-linuxbridge-agent | grep -v grep

    重新创建云主机,成功!
    Error2-OK

    这是因为sudo默认需要tty终端,修改下/etc/sudoers文件,注释掉Default requiretty即可

    [[email protected] ~]# chmod u+w /etc/sudoers
    [[email protected] ~]# vim /etc/sudoers
    ...
    #Defaults    requiretty
