Cell模块是Nano集群的资源节点，用于组成虚拟化资源池，在本地创建、管理和释放虚拟机实例。
由于涉及网络配置，建议使用专用Installer进行部署，项目最新版本请访问此地址
环境要求
- CentOS 7 x86
- Golang 1.20
准备依赖的framework
$git clone https://github.com/project-nano/framework.git
准备编译源代码
$git clone https://github.com/project-nano/cell.git
编译
$cd cell
$go build
编译成功在当前目录生成二进制文件cell
环境要求
- CentOS 7 x86
执行以下指令，启动Cell模块
$./cell start
也可以使用绝对地址调用或者写入开机启动脚本，比如
$/opt/nano/cell/cell start
模块运行日志输出在log/cell.log文件中，用于查错和调试
由于Cell节点依赖Core模块进行自动网络识别，所以集群工作时必须最先启动Core模块，再启动Cell节点。
此外，除了模块启动功能，Cell还支持以下命令参数启动
| 命令名 | 说明 |
|---|---|
| start | 启动服务 |
| stop | 停止服务 |
| status | 检查当前服务状态 |
| halt | 强行中止服务（用于服务异常时重启） |
Cell模块配置信息存放在config路径文件中，修改后需要重启模块生效
文件config/domain.cfg管理Cell模块的域通讯信息，域参数必须与Core模块一致才能成功识别
| 参数 | 值类型 | 默认值 | 必填 | 说明 |
|---|---|---|---|---|
| domain | 字符串 | nano | 是 | 通讯域名称，用于节点间识别 |
| group_address | 字符串 | 224.0.0.226 | 是 | 通讯域组播地址，用于服务发现 |
| group_port | 整数 | 5599 | 是 | 通讯域组播端口，用于服务发现 |
| timeout | 整数 | 10 | 交易处理超时时间，单位：秒 |
示例配置文件如下
{
"domain": "nano",
"group_address": "224.0.0.226",
"group_port": 5599
}模块主要目录和文件如下
| 目录/文件 | 说明 |
|---|---|
| cell | 模块二进制执行文件 |
| config/ | 配置文件存储目录 |
| data/ | 模块运行数据存储目录 |
| log/ | 运行日志存储目录 |
Cell is the resource node of Nano cluster, forming a virtualized resource pool. It creates, manages, and releases local virtual machine instances.
It is recommended to use a dedicated Installer for deployment. For the latest project version, please visit this address.
Full Source Code of the Project
Environment requirements
- CentOS 7 x86
- Golang 1.20
Prepare the framework dependencies
$git clone https://github.com/project-nano/framework.git
Prepare the source code for compilation
$git clone https://github.com/project-nano/cell.git
Compile
$cd cell
$go build
The binary file "cell" will be generated in the current directory when success
Environment
- CentOS 7 x86
start module
$./cell start
Alternatively, you can use an absolute address or write it into a startup script, such as:
$/opt/nano/cell/cell start
The running log is output on the file: log/core.log
Since the Cell nodes depend on the Core module for automatic network recognition, you must start the Core module before Cell nodes.
Core also supports the following command
| Command name | Explanation |
|---|---|
| start | Start service |
| stop | Stop service |
| status | Check current service status |
| halt | Force abort service when exception occurs |
Cell module configuration information is stored in files under the config path, and modifications require a restart of the module to take effect.
The file config/domain.cfg manages the domain communication information for the Cell module.
| Parameter | Value Type | Default Value | Required | Explanation |
|---|---|---|---|---|
| domain | String | nano | Yes | The name of the communication domain, used for cluster identification |
| group_address | String | 224.0.0.226 | Yes | Multicast address of the communication domain, used for service discovery |
| group_port | Integer | 5599 | Yes | Multicast port of the communication domain, used for service discovery |
| timeout | Integer | 10 | Transaction timeout in seconds |
An example configuration file is as follows:
{
"domain": "nano",
"group_address": "224.0.0.226",
"group_port": 5599
}| Directory/File | Explanation |
|---|---|
| cell | The binary execution file of the module |
| config/ | The storage directory for configurations |
| data/ | The storage directory for operation data |
| log/ | The storage directory for logs |
