cloudstack 安装中遇到的错误问题，以及解决方案

安装cloudstack-agent后，添加到management下总是不成功的原因有如下几点：

1. 先查看日志/var/log/cloudstack/agent/agent.log发现有如下错误：

Unable to start agent: Failed to get private nic name

agent在启动时，默认会创建cloudbr0和cloudbr1两个网桥
如果想修改为其它名字，那么需要在配置文件/etc/cloudstack/agent/agent.properties里指定修改两面两个参数

private.network.device
public.network.device

因在配置网络地址里配置的文件为
/etc/sysconfig/network-scripts/ifcfg-eno1
所以修改上述文件内容为

private.network.device=eno1
public.network.device=eno1

还修改了host

host=

2. 从UI界面上添加总是提示java解析错误，查询 /var/log/cloudstack/management/management-server.log 日志提示如下错误：

2.1 先在management日志中过滤cloudstack-agent字样的信息：

 cat /var/log/cloudstack/management/management-server.log | grep cloudstack-setup-agent

cloudstack-setup-agent  -m 172.18.18.131 -z 1 -p 1 -c 1 -g db645bf1-71ff-3542-a921-77b76fa40ae8 -a -s  --pubNic=cloudbr0 --prvNic=cloudbr0 --guestNic=cloudbr0 --hypervisor=kvm

然后手动在agent端进行启动，输入如下命令即可，其中-m后面的ip以及Nic名称更换为对应的机器即可：

网卡查询可以通过ip addr就能查询到相应的信息

cloudstack-setup-agent  -m 172.18.18.131 -z 1 -p 1 -c 1 -g db645bf1-71ff-3542-a921-77b76fa40ae8 -a -s  --pubNic=cloudbr0 --prvNic=cloudbr0 --guestNic=cloudbr0 --hypervisor=kvm
