<h2 id="简介.md">简介</h2>
操作系统作为衔接应用和硬件的基础软件，如何调整系统和应用配置，充分发挥软硬件能力，从而提升业务性能，对用户来说至关重要。然而，运行在操作系统上的业务类型成百上千，应用形态千差万别，对资源的要求各不相同，且当前硬件和基础软件组成的应用环境涉及高达7000多个配置对象，随着调优对象的增加，调优所需的时间成本以指数级增长，配置调优成为了一项极其复杂的工程，超出了一般工程师的能力范围。为了应对这些挑战，A-Tune就应运而生了。
A-Tune是一款基于openEuler系统开发的性能智能自优化的基础软件，它利用人工智能技术，对应用建立精准的系统画像，通过AI感知并推理出业务特征，从而进行智能决策，匹配得出最佳的系统配置组合，使业务处于最佳运行状态。
![](figures/zh-cn_image_0215192422.png)
<h2 id="架构.md">架构</h2>
A-Tune核心技术架构如下图，主要包括智能决策、系统画像和交互系统三层。
- 智能决策层：包含感知和决策两个子系统，分别承担对应用的智能感知和对系统的调优决策。
- 系统画像层：主要包括标注和学习系统，标注系统用于业务模型的聚类，学习系统用于业务模型的学习和分类。
- 交互系统层：用于各类系统资源的监控和配置，其中调优策略执行在本层进行。

本章介绍如何安装和部署A-Tune。
<h2 id="软硬件要求.md">软硬件要求</h2>
## 硬件要求<a name="section175931749114410"></a>
- 鲲鹏920处理器
## 软件要求<a name="section19201810164619"></a>
- 操作系统：openEuler 1.0
<h2 id="环境准备.md">环境准备</h2>
安装openEuler系统，安装方法参考《openEuler 1.0 安装指南》。
<h2 id="安装A-Tune.md">安装A-Tune</h2>
本章介绍A-Tune的安装模式和安装方法。
<h2 id="安装模式介绍.md">安装模式介绍</h2>
A-Tune支持单机模式和分布式模式安装：
- 单机模式
client和server安装到同一台机器上。
- 分布式模式
client和server分别安装在不同的机器上。
![](figures/zh-cn_image_0214540005.png)
<h2 id="安装操作.md">安装操作</h2>
安装A-Tune的操作步骤如下：
1. 挂载openEuler的iso文件。
```
# mount openEuler-1.0-aarch64-dvd.iso /mnt
```
2. 配置本地yum源。
```
# vim /etc/yum.repos.d/local.repo
```
配置内容如下所示：
```
[local]
name=local
baseurl=file:///mnt
gpgcheck=0
enabled=1
```
3. 安装A-Tune服务端。
>![](public_sys-resources/icon-note.gif) **说明：**
>本步骤会同时安装服务端和客户端软件包，对于单机部署模式，请跳过**步骤4**。
```
# yum install atune -y
```
4. 安装A-Tune客户端。
```
# yum install atune-client -y
```
5. 验证是否安装成功。
```
# rpm -qa | grep atune
atune-client-xxx
atune-db-xxx
atune-xxx
```
有如上回显信息表示安装成功。
<h2 id="部署A-Tune.md">部署A-Tune</h2>
本章介绍A-Tune的配置部署。
<h2 id="配置介绍.md">配置介绍</h2>
A-Tune配置文件/etc/atuned/atuned.cnf的配置项说明如下：
- A-Tune服务启动配置
可根据需要进行修改。
- address：系统grpc服务的侦听地址，默认为127.0.0.1，若为多机部署，需进行修改。
- port：系统grpc服务的侦听端口，范围为0\~65535未使用的端口。
- rest\_port：系统restservice的侦听端口, 范围为0\~65535未使用的端口。
- sample\_num：系统执行analysis流程时采集样本的数量。
- system信息
system为系统执行相关的优化需要用到的参数信息，必须根据系统实际情况进行修改。
- disk：执行analysis流程时需要采集的对应磁盘的信息或执行磁盘相关优化时需要指定的磁盘。
- network：执行analysis时需要采集的对应的网卡的信息或执行网卡相关优化时需要指定的网卡。
- user：执行ulimit相关优化时用到的用户名。目前只支持root用户。
- tls：开启A-Tune的gRPC和http服务SSL/TLS证书校验，默认不开启。开启TLS后atune-adm命令在使用前需要设置以下环境变量方可与服务端进行通讯：
- export ATUNE\_TLS=yes
- export ATUNE\_CLICERT=<客户端证书路径\>
- tlsservercertfile：gPRC服务端证书路径。
- tlsserverkeyfile：gPRC服务端秘钥路径。
- tlshttpcertfile：http服务端证书路径。
- tlshttpkeyfile：http服务端秘钥路径。
- tlshttpcacertfile：http服务端CA证书路径。
- 日志信息
根据情况修改日志的路径和级别，默认的日志信息在/var/log/message中。
- monitor信息
为系统启动时默认采集的系统的硬件信息。

<h2 id="启动A-Tune.md">启动A-Tune</h2>
A-Tune安装完成后，需要启动A-Tune服务才能使用。
- 启动atuned服务：
```
$ systemctl start atuned
```
- 查询atuned服务状态：
```
$ systemctl status atuned
```
若回显为如下，则服务启动成功。
![](figures/zh-cn_image_0214540398.png)
