|
|
|
在继续操作之前,我们推荐您先阅读[《写在前面》](../../prepare),这可以快速帮助你了解 Halo。
|
|
|
:::
|
|
|
|
|
|
## 创建容器组
|
|
|
|
|
|
1. 在系统任意位置创建一个文件夹,此文档以 `~/halo-app` 为例。
|
|
|
|
|
|
```bash
|
|
|
mkdir ~/halo-app && cd ~/halo-app
|
|
|
```
|
|
|
|
|
|
:::info
|
|
|
注意:后续操作中,Halo 的所有相关数据都会保存在这个目录,请妥善保存。
|
|
|
:::
|
|
|
|
|
|
2. 创建 `docker-compose.yaml`
|
|
|
|
|
|
此文档提供三种场景的 Docker Compose 配置文件,请根据你的需要选择一种。
|
|
|
|
|
|
:::info
|
|
|
需要注意的是,此文档为了更加方便的管理配置,所有与 Halo 相关的配置都使用 Docker 环境变量代替,所以无需创建 application.yaml 文件。
|
|
|
:::
|
|
|
|
|
|
1. 仅创建 Halo 实例(使用默认的 H2 数据库):
|
|
|
|
|
|
```yaml {18-19}
|
|
|
version: "3"
|
|
|
|
|
|
services:
|
|
|
halo:
|
|
|
image: halohub/halo:1.5.5
|
|
|
container_name: halo
|
|
|
restart: on-failure:3
|
|
|
volumes:
|
|
|
- ./:/root/.halo
|
|
|
- /etc/timezone:/etc/timezone:ro
|
|
|
- /etc/localtime:/etc/localtime:ro
|
|
|
ports:
|
|
|
- "8090:8090"
|
|
|
environment:
|
|
|
- SERVER_PORT=8090
|
|
|
- SPRING_DATASOURCE_DRIVER_CLASS_NAME=org.h2.Driver
|
|
|
- SPRING_DATASOURCE_URL=jdbc:h2:file:~/.halo/db/halo
|
|
|
- SPRING_DATASOURCE_USERNAME=admin
|
|
|
- SPRING_DATASOURCE_PASSWORD=o#DwN&JSa56
|
|
|
- HALO_ADMIN_PATH=admin
|
|
|
- HALO_CACHE=memory
|
|
|
```
|
|
|
|
|
|
:::info
|
|
|
您可以前往 <https://hub.docker.com/r/halohub/halo> 查看最新版本镜像,我们推荐使用具体版本号的镜像,但也提供了 `latest` 标签的镜像,它始终是最新的。
|
|
|

|
|
|

|
|
2. 创建 Halo + MySQL 的实例:
|
|
|
|
|
|
```yaml {22-23,45}
|
|
|
version: "3"
|
|
|
|
|
|
services:

|
|
halo_server:
|
|
|

|
|
|
container_name: halo_server

- SPRING_DATASOURCE_DRIVER_CLASS_NAME=com.mysql.cj.jdbc.Driver
|
|
|
- SPRING_DATASOURCE_URL=jdbc:mysql://halo_mysql:3306/halodb?characterEncoding=utf8&useSSL=false&serverTimezone=Asia/Shanghai&allowPublicKeyRetrieval=true
|
|
|
- SPRING_DATASOURCE_USERNAME=root
|
|
|
- SPRING_DATASOURCE_PASSWORD=o#DwN&JSa56
|
|
|
- HALO_ADMIN_PATH=admin
|
|
|
- HALO_CACHE=memory
|
|
|
|
|
|
halo_mysql:
|
|
|
image: mysql:8.0.27
|
|
|
container_name: halo_mysql
|
|
|
restart: on-failure:3
|
|
|
networks:

3. 启动 Halo 服务
|
|
|
|
|
|
```bash
|
|
|
docker-compose up -d
|
|
|
```
|
|
|
|
|
|
4. 打开 `http://ip:端口号` 即可看到安装引导界面。
|
|
|
|
|
|
:::tip
|
|
|
如果需要配置域名访问,建议先配置好反向代理以及域名解析再进行初始化。如果通过 `http://ip:端口号` 的形式无法访问,请到服务器厂商后台将运行的端口号添加到安全组,如果服务器使用了 Linux 面板,请检查此 Linux 面板是否有还有安全组配置,需要同样将端口号添加到安全组。
|
|
|
:::
|
|
|
|
|
|
## 反向代理
|
|
|
|
|
|
你可以在下面的反向代理软件中任选一项,我们假设你已经安装好了其中一项,并对其的基本操作有一定了解。如果你对 Nginx 不熟悉,我们推荐使用 [OneinStack](./oneinstack) 来管理 Nginx。
|
|
|
|
|
|
### Nginx
|
|
|
|
|
|
```nginx
|
|
|
upstream halo {
|
|
|
server 127.0.0.1:8090;
|
|
|
}
|
|
|
server {
|
|
|
listen 80;
|
|
|
listen [::]:80;
|
|
|
server_name www.yourdomain.com;
|
|
|
client_max_body_size 1024m;
|
|
|
location / {
|
|
|
proxy_pass http://halo;
|
|
|
proxy_set_header HOST $host;
|
|
|
proxy_set_header X-Forwarded-Proto $scheme;
|
|
|
proxy_set_header X-Real-IP $remote_addr;
|
|
|
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
|
|
|
}
|
|
|
}
|
|
|
```
|
|
|
|
|
|
### Caddy 1.x
|
|
|
|
|
|
```txt
|
|
|
https://www.yourdomain.com {
|
|
|
gzip
|
|
|
tls your@email.com
|
|
|
proxy / localhost:8090 {
|
|
|
transparent
|
|
|
}
|
|
|
}
|
|
|
```
|
|
|
|
|
|
### Caddy 2.x
|
|
|
|
|
|
```txt
|
|
|
www.yourdomain.com
|
|
|
|
|
|
encode gzip
|
|
|
|
|
|
reverse_proxy 127.0.0.1:8090
|
|
|
```
|
|
|
|
|
|
以上配置都可以在 <https://github.com/halo-dev/halo-common> 找到。

|
## 更新容器组
|
|
|
|
|
|
:::info
|
|
|
我们假设您的 Halo 服务容器是按照 [使用 Docker Compose 部署 Halo](docker-compose.md) 中的方式启动的。如有不同,请根据实际情况修改。
|
|
|
:::
|
|
|
|
|
|
1. 停止运行中的容器组
|
|
|
|
|
|
```bash
|
|
|
cd ~/halo-app && docker-compose stop
|
|
|
```
|
|
|
|
|
|
2. 备份数据(重要)
|
|
|
|
|
|
```bash
|
|
|
cp -r ~/halo-app ~/halo-app.archive
|
|
|
```
|
|
|
|
|
|
> 需要注意的是,`halo-app.archive` 文件名不一定要根据此文档命名,这里仅仅是个示例。
|
|
|
|
|
|
3. 清空 [leveldb 或 Redis](../../config.md#缓存) 缓存(如果有使用 leveldb 或 Redis 作为缓存策略)
|
|
|
|
|
|
```bash
|
|
|
rm -rf ~/halo-app/.leveldb
|
|
|
|
|
|
rm -rf ~/halo-app/redis
|
|
|
```
|
|
|
|
|
|
4. 更新 Halo 服务
|
|
|
|
|
|
针对使用 `latest` 标签镜像的更新:
|
|
|
|
|
|
```bash
|
|
|
docker-compose pull && docker-compose up -d
|
|
|
```
|
|
|
|
|
|
:::info
|
|
|
注意,当您的 `Docker` 镜像源非官方源时,执行 `docker-compose pull` 命令时可能无法获取到最新的 `latest` 标签的镜像。
|
|
|
:::
|
|
|
|
|
|
针对使用具体版本标签镜像的更新:
|
|
|
|
|
|
修改 `docker-compose.yaml` 中配置的镜像版本。
|
|
|
|
|
|
```yaml {3}
|
|
|
services:
|
|
|
halo_server:
|
|
|
image: halohub/halo:1.5.5
|
|
|
container_name: halo_server
|
|
|
```
|
|
|
|
|
|
5. 启动容器组:
|
|
|
|
|
|
```bash
|
|
|
docker-compose up -d
|
|
|
```
|
