安装 Podman
安装 podman 很简单验证安装创建一个 pod 用于安装 Nginx 和 Affine- podman pod create --name mypod -p 80:8080
复制代码 注意:需要在/etc/sysctl.conf中加入net.ipv4.ip_unprivileged_port_start=80才能创建 80 端口映射
安装 Nginx
创建对应的文件夹
- mkdir -p /opt/serves/nginx/app
- mkdir -p /opt/serves/nginx/conf
- mkdir -p /opt/serves/nginx/logs
复制代码 创建 bitnami 的 Nginx 容器
- podman run -d --pod mypod --name nginx \
- -v /opt/serves/nginx/app:/app \
- -v /opt/serves/nginx/conf:/opt/bitnami/nginx/conf \
- -v /opt/serves/nginx/logs:/opt/bitnami/nginx/logs \
- bitnami/nginx:latest
复制代码 需要注意的点:
- 用--pod mypod将容器加入 pod 中
- 浏览器访问http://IP检查 Nginx 是否正常运行
安装 Affine
创建对应的文件夹
- mkdir -p /opt/serves/affine/postgres/pgdata
- mkdir -p /opt/serves/affine/storage
- mkdir -p /opt/serves/affine/config
复制代码 通过 podman 命令安装 affine
虽然 Affine 官方提供了 docker-compose.yaml 文件,但是 podman comopse 无法直接将创建的容器加入 pod 中,因此需要用对应的命令逐个创建容器。
这是官方提供的 compose 和 env 文件,我们不使用它们,而是直接把环境变量和参数在命令行中设置好

复制代码 创建 Redis 容器
通过观察compose文件,可以看出我们需要创建 Redis、Postgres、Affine Migration 和 Affine Server 四个容器,我们从 Redis 开始
Redis 对应的部分是:- redis:
- image: redis
- container_name: affine_redis
- healthcheck:
- test: ['CMD', 'redis-cli', '--raw', 'incr', 'ping']
- interval: 10s
- timeout: 5s
- retries: 5
- restart: unless-stopped
复制代码 转换成 podman 命令就是:- podman run -d --pod mypod --name affine_redis \
- --restart unless-stopped \
- --health-cmd "redis-cli --raw incr ping" \
- --health-interval 10s \
- --health-timeout 5s \
- --health-retries 5 redis
复制代码 可以看到创建 Redis 容器还是比较简单的,没有什么需要配置的地方
创建 Postgres 容器
不需要等待 Redis 运行,继续创建 Postgres 容器
Postgres 对应的部分是:- postgres:
- image: pgvector/pgvector:pg16
- container_name: affine_postgres
- volumes:
- - ${DB_DATA_LOCATION}:/var/lib/postgresql/data
- environment:
- POSTGRES_USER: ${DB_USERNAME}
- POSTGRES_PASSWORD: ${DB_PASSWORD}
- POSTGRES_DB: ${DB_DATABASE:-affine}
- POSTGRES_INITDB_ARGS: '--data-checksums'
- # you better set a password for you database
- # or you may add 'POSTGRES_HOST_AUTH_METHOD=trust' to ignore postgres security policy
- POSTGRES_HOST_AUTH_METHOD: trust
- healthcheck:
- test:
- ['CMD', 'pg_isready', '-U', "${DB_USERNAME}", '-d', "${DB_DATABASE:-affine}"]
- interval: 10s
- timeout: 5s
- retries: 5
- restart: unless-stopped
复制代码 转换后的 podman 命令明显比 Redis 长了很多:- podman run -d --pod mypod --name affine_postgres \ --restart unless-stopped \
- -v /opt/serves/affine/postgres/pgdata:/var/lib/postgresql/data \
- -e POSTGRES_USER=affine \
- -e POSTGRES_PASSWORD=[你的密码] \
- -e POSTGRES_DB=affine \
- -e POSTGRES_INITDB_ARGS='--data-checksums' \
- -e POSTGRES_HOST_AUTH_METHOD=trust \
- --health-cmd "pg_isready -U affine -d affine" \
- --health-interval 10s --health-timeout 5s --health-retries 5 \
- pgvector/pgvector:pg16
复制代码 需要注意的地方:
- 把DB_USERNAME、DB_PASSWORD这些环境变量替换为真实的用户名、密码...
创建 Affine Migration 容器
在执行这一步之前需要等待 Redis 和 Postgres 的状态转变为healthy,可以通过podman ps查看这两个容器的状态
Affine Migration 对应的部分是:- affine_migration:
- image: ghcr.io/toeverything/affine:${AFFINE_REVISION:-stable}
- container_name: affine_migration_job
- volumes:
- # custom configurations
- - ${UPLOAD_LOCATION}:/root/.affine/storage
- - ${CONFIG_LOCATION}:/root/.affine/config
- command: ['sh', '-c', 'node ./scripts/self-host-predeploy.js']
- env_file:
- - .env
- environment:
- - REDIS_SERVER_HOST=redis
- - DATABASE_URL=postgresql://${DB_USERNAME}:${DB_PASSWORD}@postgres:5432/${DB_DATABASE:-affine}
- - AFFINE_INDEXER_ENABLED=false
- depends_on:
- postgres:
- condition: service_healthy
- redis:
- condition: service_healthy
复制代码 转换后的 podman 命令为:- podman run --rm --pod mypod --name affine_migration_job \
- -v /opt/serves/affine/storage:/root/.affine/storage \
- -v /opt/serves/affine/config:/root/.affine/config \
- -e REDIS_SERVER_HOST=localhost \
- -e DATABASE_URL=postgresql://affine:[密码]@affine_postgres:5432/$affine \
- -e AFFINE_INDEXER_ENABLED=false \
- ghcr.io/toeverything/affine:stable \
- sh -c 'node ./scripts/self-host-predeploy.js'
复制代码 这其实是一个数据迁移步骤,执行完毕后用podman ps也不会看到相关容器,不必担心,需要注意的是:
- 由于所有容器都在一个 pod 中,REDIS_SERVER_HOST直接设置为localhost即可
- 如果出现User was denied access on the database错误,进入 postgres 容器创建对应数据库
- # 1. 进入容器
- podman exec -it affine_postgres psql -U postgres
- # 2. 确认用户是否存在
- \du
- # 3. 如果没有 affine 用户,请创建:
- CREATE USER affine WITH PASSWORD '19970614yao';
- # 4. 创建数据库并授权
- CREATE DATABASE affine OWNER affine;
- GRANT ALL PRIVILEGES ON DATABASE affine TO affine;
- # 5. 刷新权限
- FLUSH PRIVILEGES;
- # 6. 退出数据库后重新运行创建affine_migration_job容器即可
复制代码 创建 Affine Server 容器
终于到了部署 Affine 的最后一步
Affine Migration 对应的部分是:- affine:
- image: ghcr.io/toeverything/affine:${AFFINE_REVISION:-stable}
- container_name: affine_server
- ports:
- - '${PORT:-3010}:3010'
- depends_on:
- redis:
- condition: service_healthy
- postgres:
- condition: service_healthy
- affine_migration:
- condition: service_completed_successfully
- volumes:
- # custom configurations
- - ${UPLOAD_LOCATION}:/root/.affine/storage
- - ${CONFIG_LOCATION}:/root/.affine/config
- env_file:
- - .env
- environment:
- - REDIS_SERVER_HOST=redis
- - DATABASE_URL=postgresql://${DB_USERNAME}:${DB_PASSWORD}@postgres:5432/${DB_DATABASE:-affine}
- - AFFINE_INDEXER_ENABLED=false
- restart: unless-stopped
复制代码 转换后的 podman 命令为:- podman run -d --pod mypod --name affine_server \
- --restart unless-stopped \
- -v /opt/serves/affine/storage:/root/.affine/storage \
- -v /opt/serves/affine/config:/root/.affine/config \
- -e REDIS_SERVER_HOST=localhost \
- -e DATABASE_URL=postgresql://affine:[密码]@localhost:5432/affine \
- -e AFFINE_INDEXER_ENABLED=false \
- ghcr.io/toeverything/affine:stable
复制代码 运行podman logs affine_server检查运行情况,应该有如下输出:- LOG [NestApplication] Nest application successfully started
- LOG [WorkspaceResolver] AFFiNE Server is running in [selfhosted] mode
- LOG [WorkspaceResolver] Listening on http://0.0.0.0:3010
- LOG [WorkspaceResolver] And the public server should be recognized as http://localhost:3010
复制代码 要注意的是:
- 由于 pod 统一映射了端口,不需要再设置端口映射
配置 Nginx 反向代理
终于我们完成了 Affine 的配置,接下来只要再配置 Nginx 反向代理让我们能访问 Affine 服务就行了
在/opt/serves/nginx/conf/server_blocks下新建一个affine.conf文件和一个default.conf文件
- affine.conf
用于把访问affine.your.domain的流量代理至 Affine 监听的 3010 端口
- server {
- listen 8080; # 映射的是pod外的80端口
- server_name affine.your.domain; # 只有通过这个域名访问的流量才会被代理至Affine
- access_log /opt/bitnami/nginx/logs/affine.log;
- error_log /opt/bitnami/nginx/logs/affine.log;
- location / {
- proxy_set_header X-Real-IP $remote_addr;
- proxy_set_header HOST $http_host;
- proxy_set_header X-NginX-Proxy true;
- proxy_pass http://localhost:3010; # 代理至 Affine监听的3010端口
- proxy_redirect off;
- }
- }
复制代码
- default.conf
用于屏蔽域名不匹配的流量(可选)
当不是通过affine.your.domain访问服务器时,直接关闭连接
- server {
- listen 8080 default_server;
- server_name _; # 匹配任何 Host
- return 444; # 直接关闭连接(也可以 404 / 503)
- }
复制代码 完成上述步骤后,即可在浏览器中通过域名访问 affine 服务
注册 systemd 服务(推荐)
由于 podman 没有守护进程,所以没法开机自启动 pod 或容器,要借助 systemd 实现自启动- podman generate systemd --name mypod --new --files
- # 会生成下面这些文件
- /opt/serves/container-doocs.service
- /opt/serves/container-affine_redis.service
- /opt/serves/container-affine_postgres.service
- /opt/serves/pod-mypod.service
- /opt/serves/container-affine_server.service
- /opt/serves/container-nginx.service
复制代码 把这些文件复制到用户的 systemd 目录下,没有这个目录就创建一个- mkdir -p ~/.config/systemd/user # 一般都有这个目录
- cp *.service ~/.config/systemd/user
复制代码 重载 systemd 并应用服务- systemctl --user daemon-reload
- systemctl --user enable --now pod-mypod.service
复制代码 导出 pod 文件(推荐)
可以导出 pod 文件,这样下次再创建 pod 就不需要这么麻烦了- podman generate kube mypod>mypod.yaml # 导出pod配置,兼容k8s
- podmam play kube mypod.yaml # 可以从yaml文件重新创建mod
