配置指南¶
Shortener 服务器的完整配置参考。
目录¶
概述¶
Shortener 服务器使用 TOML 格式进行配置。配置可以从以下位置加载:
- 配置文件(默认:
config/config.toml) - 环境变量(前缀:
SHORTENER__) - 命令行参数
优先级(从高到低):命令行 > 环境变量 > 配置文件
配置文件¶
位置¶
默认位置(按优先级顺序):
--config标志指定的路径./config/config.toml/etc/shortener/config.toml
格式¶
[server]
# 服务器设置
[shortener]
# 短代码生成设置
[admin]
# 管理员账户设置
[database]
# 数据库连接设置
[cache]
# 缓存设置
[geoip]
# GeoIP 设置
环境变量¶
环境变量使用前缀 SHORTENER__,用双下划线分隔嵌套键:
# 服务器地址
export SHORTENER__SERVER__ADDRESS=":9090"
# 数据库类型
export SHORTENER__DATABASE__TYPE="postgres"
# 启用缓存
export SHORTENER__CACHE__ENABLED="true"
# API 密钥
export SHORTENER__SERVER__API_KEY="your-secret-key"
服务器配置¶
[server]
address = ":8080" # 监听地址
site_url = "http://localhost:8080" # 公共站点 URL
api_key = "your-secret-api-key" # API 密钥(必需)
详细说明¶
address:服务器监听地址,默认:8080site_url:站点的公共 URL,用于生成短链接api_key:用于认证的 API 密钥,使用openssl rand -base64 32生成
短链接配置¶
[shortener]
code_length = 6 # 短代码长度(4-16)
code_charset = "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"
管理员配置¶
数据库配置¶
SQLite¶
PostgreSQL¶
[database]
type = "postgres"
log_level = 1
[database.postgres]
host = "localhost"
port = 5432
user = "postgres"
password = "postgres"
database = "shortener"
sslmode = "disable"
timezone = "Asia/Shanghai"
MySQL¶
[database]
type = "mysql"
log_level = 1
[database.mysql]
host = "localhost"
port = 3306
user = "root"
password = "root"
database = "shortener"
charset = "utf8mb4"
缓存配置¶
Redis¶
[cache]
enabled = true
type = "redis"
expire = 3600
prefix = "shorten:"
[cache.redis]
host = "localhost"
port = 6379
password = ""
db = 0
Valkey¶
[cache]
enabled = true
type = "valkey"
expire = 3600
[cache.valkey]
host = "localhost"
port = 6379
password = ""
db = 0
GeoIP 配置¶
GeoIP 功能用于追踪访问者的地理位置信息。默认禁用,需要手动配置。
[geoip]
enabled = false # 默认禁用
type = "ip2region"
[geoip.ip2region]
path = "data/ip2region.xdb"
mode = "vector"
version = "4"
启用 GeoIP¶
要启用 GeoIP 功能,需要:
-
下载 ip2region 数据库文件:
-
在配置文件中启用:
-
重启服务
详细的 GeoIP 配置和使用说明,请参阅 GeoIP 配置指南。
配置示例¶
开发环境¶
[server]
address = ":8080"
site_url = "http://localhost:8080"
api_key = "dev-api-key"
[admin]
username = "admin"
password = "admin123"
[database]
type = "sqlite"
[database.sqlite]
path = "data/shortener.db"
[cache]
enabled = false
[geoip]
enabled = false
生产环境¶
[server]
address = ":8080"
site_url = "https://short.example.com"
api_key = "${SHORTENER_API_KEY}"
[admin]
username = "${SHORTENER_ADMIN_USER}"
password = "${SHORTENER_ADMIN_PASS}"
[database]
type = "postgres"
[database.postgres]
host = "postgres"
port = 5432
user = "shortener"
password = "${POSTGRES_PASSWORD}"
database = "shortener"
sslmode = "require"
[cache]
enabled = true
type = "redis"
[cache.redis]
host = "redis"
port = 6379
password = "${REDIS_PASSWORD}"
[geoip]
enabled = true
[geoip.ip2region]
path = "/var/lib/shortener/ip2region.xdb"
最佳实践¶
- 使用环境变量存储敏感数据(密码、API 密钥)
- 不同环境使用不同配置(开发、生产)
- 定期轮换 API 密钥和密码
- 生产环境使用适当的日志级别
- 启用缓存以提高性能
