Supported OS: openEuler 1.0 or later

### Method 1 (applicable to common users): Use the default A-Tune of openEuler.

```bash
yum install -y atune

### Method 2 (applicable to developers): Use the source code of the local repository for installation.

#### 1. Install dependent system software packages.
```bash
yum install -y golang-bin python3 perf sysstat hwloc-gui
```

#### 2. Install Python dependent packages.
```bash
yum install -y python3-dict2xml python3-flask-restful python3-pandas python3-scikit-optimize python3-xgboost
```
Or
```bash
pip3 install dict2xml Flask-RESTful pandas scikit-optimize xgboost
```

#### 3. Download the source code.
```bash
mkdir -p /home/gopath/src
cd /home/gopath/src
git clone https://gitee.com/openeuler/A-Tune.git atune

#### Load and start the atuned service.
```bash

This command is used to list the supported workload types, profiles, and the values of Active.

Format:

atune-adm list

Example:
```bash
atune-adm list
```

#### The analysis command.
This command is used to collect real-time statistics from the system to identify and automatically optimize workload types.

Format:

atune-adm analysis [OPTIONS] [APP_NAME]

Example 1: Use the default model for classification and identification.
```bash
atune-adm analysis
```
Example 2: Use the user-defined training model for recognition.
```bash
atune-adm analysis –model ./model/new-model.m
```
Example 3: Specify the current system application as MySQL, which is for reference only.
```bash
atune-adm analysis mysql
```
