gitlab配置webhook报错解决

gitlab使用webhook向jenkins发送请求，报错 Requests to the local network are not allowed

以下是官方给出解释：

链接：https://docs.gitlab.com/ee/security/webhooks.html

If you have non-GitLab web services running on your GitLab server or within its local network, these may be vulnerable to exploitation via Webhooks.

With?Webhooks, you and your project maintainers and owners can set up URLs to be triggered when specific things happen to projects. Normally, these requests are sent to external web services specifically set up for this purpose, that process the request and its attached data in some appropriate way.

Things get hairy, however, when a Webhook is set up with a URL that doesn't point to an external, but to an internal service, that may do something completely unintended when the webhook is triggered and the POST request is sent.

Because Webhook requests are made by the GitLab server itself, these have complete access to everything running on the server (http://localhost:123) or within the server's local network (http://192.168.1.12:345), even if these services are otherwise protected and inaccessible from the outside world.

If a web service does not require authentication, Webhooks can be used to trigger destructive commands by getting the GitLab server to make POST requests to endpoints like "http://localhost:123/some-resource/delete".

To prevent this type of exploitation from happening, starting with GitLab 10.6, all Webhook requests to the current GitLab instance server address and/or in a private network will be forbidden by default. That means that all requests made to 127.0.0.1, ::1 and 0.0.0.0, as well as IPv4 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16 and IPv6 site-local (ffc0::/10) addresses won't be allowed.

This behavior can be overridden by enabling the option?"Allow requests to the local network from hooks and services"?in the?"Outbound requests"?section inside the Admin area under?Settings?(/admin/application_settings):

大致意思 gitlab 10.6 版本以后为了安全，不允许向本地网络发送webhook请求，如果想向本地网络发送webhook请求，则需要使用管理员帐号登录，默认管理员帐号是admin@example.com，密码就是你gitlab搭建好之后第一次输入的密码，登录之后，?点击Configure Gitlab ，如下图所示

即可进入Admin area，在Admin area中，在settings标签下面，找到OutBound Request，勾选上Allow requests to the local network from hooks and services ，保存更改即可解决问题

2、gitlab 页面 503 错误 之前好好的，突然503错误

解决： 内存不够了，清理一下缓存， gitlab很占内存，至少得5G以上才可以启动

3、获取gitlabtoken

4、修改gitlab密码

转自   https://www.cnblogs.com/kevingrace/p/5985918.html

Gitlab安装后，http://localhost访问，首次访问的时候，如果不知道管理员账号和密码，尽管可以注册用户，但注册的用户都不是管理员。这个时候，可以重置管理员的密码，管理员默认是root。
重置管理员密码（密码要是8位）的方法如下：

[root@gitlab ~]# gitlab-rails console production
Loading production environment (Rails 4.1.1)
irb(main):001:0> user = User.where(id:1).first
irb(main):002:0> user.password='12345678'
irb(main):003:0> user.save!

这样，Gitlab管理员的登录权限就是：root/12345678，管理员的默认邮箱是部署机的本机邮箱，也是从本机发的邮件。这也就是为什么在开头要安装postfix。

6、设置用户、组、权限
