在配置文件中，将 PostgreSQL 数据库的默认密码进行修改。暴露在公网的数据库使用默认密码非常危险。

在配置文件中，将 Tiny Tiny RSS 服务的部署网址修改为我们实际的部署网址。比如我的部署网址是 :https://rss.yirenliu.cn

注意，如果你的部署 URL 包含端口（默认部署端口为 181 端口），那么这里的 URL 也需要加上端口号，格式为 {网址}:{端口}不过不必担心，如果你这里的 URL 配置不正确，那么访问 Tiny Tiny RSS 的时候，Tiny Tiny RSS 会提醒你修改这里的值为正确的 URL，按照提醒进行配置即可

上面的docker-compose中opencc不支持arm构架，故采用下面的docker run命令：

这里有个bug左边的命令粘贴过去自动多了-e DB_PASS=n*9FEapt install docker-compose aTlPhA]jt \命令，不知道为啥,测试好像是密码的问题
