Ruby on rails GitLab 7.4.3 HTTP代码500:无法连接到服务器

我用omnibus安装程序安装了GitLab，现在我遇到了一个问题，当我尝试访问该网站时，我变成了一个http错误500。我使用nginx作为web服务器，在端口8000下可以访问gitlab

这是我在production.log中看到的错误消息：

==> ./gitlab/gitlab-rails/production.log <==
Started GET "/" for 212.227.35.68 at 2014-11-14 10:15:07 -0600

PG::Error (could not connect to server: No such file or directory

connections on Unix domain socket "/tmp/.s.PGSQL.5432"?

以及gitlab.rb配置文件：

# Change the external_url to the address your users will type in their browser
external_url 'http://gitlab.domain.com:8000'

# External URL to reach the GitLab CI Coordinator at
ci_external_url 'http://ci.domain.com:8000'

一切都在Debian 7服务器上运行，我安装了ActualGitlab 7.4.3版。 安装过程完成后，我修改了gitlab.rb，并开始重新配置gitlab

gitlab ctl重新配置

。之后，我用

gitlab ctl start

启动了gitlab

编辑：

---

我已经测试过为CI打开网站，但是出现了相同的错误消息。

数据库服务器中的问题。Rails应用程序尝试通过Unix域套接字“/tmp/.s.PGSQL.5432”访问if

显示PG设置和database.yml

---

PG可能只侦听TCP套接字，而不侦听UNIX。您应该对其进行配置。

我已找到此问题的解决方案，但我创建了一个新问题。 首先是解决方案：

gitlab安装程序在

/tmp/.s.PGSQL.5432

下搜索该文件，我可以在

/var/run/postgresql/.s.PGSQL.5432

下找到该文件，因此我创建了一个与

ln-s/var/run/postgresql/.s.PGSQL.5432

的链接，现在该错误不再出现

---

下一个错误是没有用于postgresql的gitlab用户，但我已经创建了一个。看看这篇帖子：

我也遇到了同样的问题，找到了一种更为激进的方法：

sudo gitlab-ctl stop

mv /var/opt/gitlab/postgresql /var/opt/gitlab/postgresql.bak

sudo gitlab-ctl reconfigure
sudo gitlab-ctl start

---

由于PostgreSQL文件在某种程度上是“损坏的”，Gitlab只是重新生成它们。我所有的旧数据（设置、用户、存储库和注释）仍然存在。

可能相关：如果只发生在自定义端口上，请将其添加到标题中。不，这对我没有帮助。错误是相同的，防火墙不会产生任何问题。Database.yml:

#此文件由gitlab ctl管理。手动更改将被删除！要更改以下内容，请编辑/etc/gitlab/gitlab.rb#并运行“sudo gitlab ctl reconfigure”。生产：适配器：postgresql编码：unicode数据库：gitlab HQ_生产池：10用户名：'gitlab'密码：主机：端口：5432套接字：

，因此您应该编辑database.yml以使用tcp，通过Gitlab设置的主机和端口，当我将其设置为tcp时，postgresql无法再启动。显示您的数据库。yml

#此文件由Gitlab ctl管理。手动更改将被删除！要更改以下内容，请编辑/etc/gitlab/gitlab.rb#并运行“sudo gitlab ctl reconfigure”。生产：适配器：postgresql编码：unicode数据库：gitlabhq_生产池：10用户名：“gitlab”密码：主机：端口：5432套接字：“tcp”

sudo gitlab-ctl stop

mv /var/opt/gitlab/postgresql /var/opt/gitlab/postgresql.bak

sudo gitlab-ctl reconfigure
sudo gitlab-ctl start
