linux - 如果我是普通用户，我会收到一条错误消息，提示 :/var/run/renderd/renderd. sock 套接字绑定(bind)失败，否则一切正常？

Question

我正在尝试按照 switch2osm.org 上的说明手动构建 map 服务器。我已经配置了一切。我有一个由用户 mayank 拥有的数据库 mayank，我正在尝试使用 renderd，但我收到此错误套接字绑定(bind)失败:/var/run/renderd/renderd.sock。现在，如果我切换到 root 并执行相同的操作，它会完美运行，没有直接的权限问题，因为我已经递归地更改了目录的所有者。但可能存在一些中间许可问题。我不能以 root 身份运行它，因为我使用的是 psql，而我的数据库 mayank 所有者是我的用户 mayank，这导致没有渲染图 block 。而且我不想重新安装我的操作系统，但认真理解这个问题的原因。请帮助我是 openstreetmaps 和 Linux 的新手。 以下是我的流程的确切代码:

下面是以 root 身份运行的，但可能是因为数据库的原因，这个过程没有生成任何图 block

Answer 1

我遇到了与您几乎相同的问题。据我所知，这背后可能有两个原因。尝试再次运行

sudo -u 'username' renderd -f -c /usr/local/etc/renderd.conf

应用建议的解决方案之一后。将“用户名”替换为运行渲染的用户名:

原因 #1 缺少写入权限

您可能没有对 /var/run/renderd/renderd.sock 文件的写入权限。

您的解决方案是更改目录的所有者:

sudo chown 'username' /var/run/renderd

和/或通过键入更改文件的所有者

sudo chown 'username' /var/run/renderd/renderd.sock

，其中“用户名”代表将运行渲染的用户。

原因#2 缺少目录

我收到了与您几乎相同的错误消息。

在我的例子中，我丢失了 /var/run/renderd 目录。我的解决方案是创建 /var/run/renderd 目录，然后更改其所有者:

sudo mkdir /var/run/renderd
sudo chown 'username' /var/run/renderd

，其中'username'是用户，它将被运行渲染。
