# Dependencies
本服务依赖于 Redis 提供长短链接映射关系存储,你需要本地安装 Redis 服务来保证短链接服务的正常运行。
```shell script
sudo apt-get update
# 安装Redis
sudo add-apt-repository ppa:chris-lea/redis-server -y
sudo apt-get update
sudo apt-get install redis-server -y
```
## Docker
TODO
## Install
安装项目依赖
```shell script
make install
```
生成可执行文件,目录位于 build/ 。默认当前平台,其他平台请参照 Makefile 或执行对应 go build 命令。
```shell script
make
```
## Usage
前往 [Release](https://github.com/CareyWang/MyUrls/releases) 下载对应平台可执行文件。
```shell script
./build/myurls -h
Usage of ./build/myurls.service:
-domain string
短链接域名 (default "s.wcc.best")
-port int
服务端口 (default 8002)
-ttl int
短链接有效期,单位(天)默认90天。 (default 90)
```
建议配合 [pm2](https://pm2.keymetrics.io/) 开启守护进程。
```shell script
pm2 start myurls.service --watch --name myurls -- -domain example.com
```
