# 操作手册

从内蒙的开发者门户上（`http://10.142.233.181:8099/index.html#/`），进入`应用管理 -> 应用列表 -> 云桌面 -> openstack源码`，从这里跳转到gogs地址，然后下载master分支最新的源码压缩包`openstack-master.tar.gz`

## 一、更新数据库（controller节点）

`openstack-master.tar.gz`里面有一个`nova.sql`，里面的内容如下：

```
alter table nova.instance_extra add ca_cert text;
alter table nova.instance_extra add server_cert text;
alter table nova.instance_extra add server_key text;
alter table nova.instance_extra add client_cert text;

alter table nova_cell0.instance_extra add ca_cert text;
alter table nova_cell0.instance_extra add server_cert text;
alter table nova_cell0.instance_extra add server_key text;
alter table nova_cell0.instance_extra add client_cert text;
```

连上数据库，执行该sql脚本，为`nova`与`nova_cell0`这个两个`database`的`instance_extra`表添加`ca_cert`、`server_cert`、`serverk_key`、`client_cert`四个字段。

## 二、更新libvirt（compute节点）

首先，先卸载`libvirt-daemon-driver-qemu`：

```
$ sudo yum -y remove libvirt-daemon-driver-qemu
```

注意，由于`openstack-nova-compute`依赖于该软件，所以卸载它也会导致`openstack-nova-compute`被卸载，那么需要重新安装`openstack-nova-compute`

然后安装我们自已编译好的这个rpm包（在`openstack-master.tar.gz`的`libvirt/rpm/`目录下）

```
$ sudo yum -y localinstall libvirt-daemon-driver-qemu-4.5.0-10.el7_6.6.x86_64.rpm
```

然后再重新安装`openstack-nova-compute`

> 当然，如果每一次都先卸载原始的libvirt-daemon-driver-qemu再安装会比较麻烦，待测试稳定后，可以把自已编译好的包加入到yum源中。当然，自已编译的包的版本，一定要是最新的，因为安装openstack-nova-compute时会安装最新的libvirt-daemon-driver-qemu

## 三、更新openstack-nova-compute（compute节点）

在`openstack-master.tar.gz`上有一个`patch.sh`，执行该脚本:

```
$ sudo ./patch.sh
```

然后重启`openstack-nova-compute`服务
