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。
```
# 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。

# 简介<a name="ZH-CN_TOPIC_0213174666"></a>
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是一款系统性能智能自优化的系统级基础软件，它结合了大数据和人工智能技术，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，使业务处于最佳的状态运行。同时，应用运行时，A-Tune还可以实时感知业务运行特征和系统负载情况，完成基于资源模型优先级的调度匹配，实现不同资源的动态分配与调度，从而充分发挥鲲鹏服务器的计算能力，使运行在鲲鹏服务器上的应用得到最佳性能表现，实现极致用户体验。
另外，A-Tune还能发挥鲲鹏芯片多核的优势，实现资源多级伸缩调度，释放鲲鹏处理器的澎湃算力，精准实现业务所需的高性能、低时延、高吞吐等业务体验。在数据库、Web、大数据等主流应用场景下，A-Tune技术使能openEuler成为鲲鹏处理器的最佳拍档。

安装和使用A-Tune，软件层面需要满足以下条件：
- 操作系统：openEuler 1.0
安装方法参考《openEuler 1.0 安装指南》。
>![](public_sys-resources/icon-note.gif) **说明：**
>- 由于A-Tune当前仅支持openEuler系统，所以其硬件要求和openEuler要求一致。
- 安装A-Tune依赖的软件包请参见[表1](#table04471527114213)

# 配置介绍<a name="ZH-CN_TOPIC_0213178456"></a>
A-Tune的详细配置保存在/etc/atuned/atuned.cnf文件中，用户根据实际系统配置进行配置
这里介绍常见配置项的含义：
- 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。
- 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。
