### 1. 查看系统的内核版本

```bash
[root@wide ~]# uname -r
3.10.0-1160.el7.x86_64
```

### 2. 将yum更新到最新版本

```bash
[root@wide ~]# yum upate -y
Complete!
```

### 3. 安装Docker所需的依赖包

```bash
[root@wide ~]# sudo yum install -y yum-utils device-mapper-persistent-data lvm2
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
* base: mirrors.bupt.edu.cn
* extras: mirrors.bupt.edu.cn
* updates: mirrors.qlu.edu.cn
Package yum-utils-1.1.31-54.el7_8.noarch already installed and latest version
Package device-mapper-persistent-data-0.8.5-3.el7_9.2.x86_64 already installed and latest version
Package 7:lvm2-2.02.187-6.el7_9.5.x86_64 already installed and latest version
Nothing to do
[root@wide ~]#
```

### 4.设置Docker的yum的源

```bash
[root@wide ~]# sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
Loaded plugins: fastestmirror, langpacks
adding repo from: https://download.docker.com/linux/centos/docker-ce.repo
grabbing file https://download.docker.com/linux/centos/docker-ce.repo to /etc/yum.repos.d/docker-ce.repo
repo saved to /etc/yum.repos.d/docker-ce.repo
```

### 5. 查看仓库所有Docker版本

```bash
[root@wide ~]# yum list docker-ce --showduplicates | sort -r
* updates: mirrors.qlu.edu.cn

### 7.启动Docker并添加开机自启动

```bash
[root@wide ~]# systemctl enable docker
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.
[root@wide ~]# systemctl start docker

```

### 8.查看docker版本

```bash
[root@wide ~]# docker --version
Docker version 23.0.3, build 3e7cbfd
```

### 9.卸载 Docker

```bash
[root@wide ~]#sudo yum remove docker \docker-client \docker-client-latest \docker-common \docker-latest \docker-latest-logrotate \docker-logrotate \docker-selinux \docker-engine-selinux \docker-engine
```

### 10.安装 Portainer

1.创建目录

```bash
[root@wide ~]# mkdir -p /data/portainer/data /data/portainer/public
```

创建一个 portainer 下的放置扩展包public文件夹
2.可以对这个扩展包进行汉化可以将汉化开展放到public下
3. 创建 portainer 卷

```bash
[root@wide ~]# docker volume create portainer_data
portainer_data
```

4.拉取最新的 Portainer

```bash
[root@wide ~]# docker pull portainer/portainer
Using default tag: latest
latest: Pulling from portainer/portainer
```

5.安装和启动
第一种：

```bash
docker run -d -p 8000:8000 -p 9443:9443 --name portainer --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce:latest
```

第二种：

```bash
docker run -d --restart=always --name portainer -p 9000:9000 -v /var/run/docker.sock:/var/run/docker.sock -v /data/portainer/data:/data -v /data/portainer/public:/public portainer/portainer
```

```bash
[root@laona portainer]# docker run -d --restart=always --name portainer -p 9000:9000 -v /var/run/docker.sock:/var/run/docker.sock -v /data/portainer/data:/data -v /data/portainer/public:/public portainer/portainer
a29864c820494afe3e465ce9b58e686851f5c6526532fe52fc4b83c1cc0b705e
```

• -v 为挂载本地文件路径到 Docker 中，用法为：-v 本地路径:docker中的路径
5.1如果防火墙开启中，需要开放端口,不然在第六步访问不了

```bash
firewall-cmd --zone=public --add-port=9000/tcp --permanent
```

6.访问 Portainer
• 地址：<http://【ip地址】:9000/>
• 操作：登录后设置你的用户名和密码，并设置本地Docker即可
