# ERROR
|
||||
|
||||
## 问题一：GitLab容器一直重启
|
||||
|
||||
|
||||
使用`docker logs`命令查询
|
||||
|
||||
```
|
||||
$ docker log CONTAINER_ID
|
||||
...
|
||||
...
|
||||
System Info:
|
||||
------------
|
||||
chef_version=14.13.11
|
||||
platform=ubuntu
|
||||
platform_version=16.04
|
||||
ruby=ruby 2.6.3p62 (2019-04-16 revision 67580) [x86_64-linux]
|
||||
program_name=/opt/gitlab/embedded/bin/chef-client
|
||||
executable=/opt/gitlab/embedded/bin/chef-client
|
||||
|
||||
|
||||
Running handlers:
|
||||
There was an error running gitlab-ctl reconfigure:
|
||||
|
||||
/etc/gitlab/gitlab.rb:1: unexpected fraction part after numeric literal
|
||||
external_url = 192.168.0.144:7002
|
||||
^~~~~~~
|
||||
/etc/gitlab/gitlab.rb:1: syntax error, unexpected tINTEGER, expecting end-of-input
|
||||
external_url = 192.168.0.144:7002
|
||||
^~~
|
||||
|
||||
Running handlers complete
|
||||
Chef Client failed. 0 resources updated in 01 seconds
|
||||
```
|
||||
|
||||
发现是`external_url`配置失误导致。解决方法如下：
|
||||
|
||||
1. 停止`gitlab`容器
|
||||
2. 修改配置文件（在主机中）`/srv/gitlab/config/gitlab.rb`
|
||||
3. 重新启动容器
|
||||
|
||||
## 问题二：GitLab导致8080端口冲突
|
||||
|
||||
### 问题复现
|
||||
|
||||
安装完`GitLab`后，修改配置文件`/etc/gitlab/gitlab.rb`
|
||||
|
||||
```
|
||||
##external_url 'http://gitlab.example.com'
|
||||
external_url 'http://localhost:8800'
|
||||
```
|
||||
|
||||
本以为这样就能修改`GitLab`端口号为`8800`了，没想到再次登录`8080`仍旧出现了`GitLab`页面
|
||||
|
||||
|
||||
|
||||
### 问题解析
|
||||
|
||||
查询哪个程序监听了`8080`端口
|
||||
|
||||
```
|
||||
# netstat -lnp | grep 8080
|
||||
tcp 0 0 127.0.0.1:8080 0.0.0.0:* LISTEN 26436/config.ru
|
||||
```
|
||||
|
||||
查询相应的进程
|
||||
|
||||
```
|
||||
# netstat -lnp | grep 26436
|
||||
tcp 0 0 127.0.0.1:8080 0.0.0.0:* LISTEN 26436/config.ru
|
||||
unix 2 [ ACC ] STREAM LISTENING 343538 26436/config.ru /var/opt/gitlab/gitlab-rails/sockets/gitlab.socket
|
||||
```
|
||||
|
||||
仍然是`GitLab`在监听`8080`端口，参考[gitlab 8.13 80 8080端口冲突问题](https://blog.csdn.net/vbaspdelphi/article/details/52979836)，查看配置文件`unicorn.rb`
|
||||
|
||||
```
|
||||
# This file is managed by gitlab-ctl. Manual changes will be
|
||||
# erased! To change the contents below, edit /etc/gitlab/gitlab.rb
|
||||
# and run `sudo gitlab-ctl reconfigure`.
|
||||
|
||||
# What ports/sockets to listen on, and what options for them.
|
||||
listen "127.0.0.1:8080", :tcp_nopush => true
|
||||
```
|
||||
|
||||
默认情况下`unicorn`同样监听`8080`端口，查询`/etc/gitlab/gitlab.rb`中相应的设置
|
||||
|
||||
```
|
||||
# cat gitlab.rb | grep unicorn
|
||||
#unicorn['port'] = 8800
|
||||
```
|
||||
|
||||
### 解决方案
|
||||
|
||||
需要在`gitlab.rb`上同时修改`unicorn`监听端口号，修改配置文件`/etc/gitlab/gitlab.rb`如下
|
||||
|
||||
```
|
||||
##external_url 'http://gitlab.example.com'
|
||||
external_url 'http://localhost:8800'
|
||||
unicorn['port'] = 8801
|
||||
```
|
||||
|
||||
重新启动`GitLab`
|
||||
|
||||
```
|
||||
# gitlab-ctl reconfigure
|
||||
# gitlab-ctl restart
|
||||
```
|
||||
|
||||
查询配置文件`/var/opt/gitlab/gitlab-rails/etc/unicorn.rb`
|
||||
|
||||
```
|
||||
# cat unicorn.rb | grep listen
|
||||
# What ports/sockets to listen on, and what options for them.
|
||||
listen "127.0.0.1:8801", :tcp_nopush => true
|
||||
```
|
||||
|
||||
测试端口号
|
||||
|
||||
```
|
||||
$ curl localhost:8080
|
||||
curl: (7) Failed to connect to localhost port 8080: Connection refused
|
||||
$ curl localhost:8800
|
||||
<!DOCTYPE html>
|
||||

|
||||

|
||||
<meta content="width=device-width, initial-scale=1, maximum-scale=1" name="viewport">

|

|

# curl localhost:8801
|
||||
<html><body>You are being <a href="http://localhost:8801/users/sign_in">redirected</a>.</body></html>
|
||||
```
|
||||
|
||||
## 问题三： [GitLab][Webhook]不允许本地连接
|
||||
|
||||
在`gitlab`仓库中设置`Webhook`，使用本地连接出现如下错误:
|
||||
|
||||
```
|
||||
Url is blocked: Requests to the local network are not allowed
|
||||
```
|
||||
|
||||
参考:[gitlab使用webhook向jenkins发送请求，报错 Requests to the local network are not allowed](https://blog.csdn.net/xukangkang1hao/article/details/80756085)
|
||||
|
||||
登录`root`账户，点击`Configure Gitlab`选项
|
||||
|
||||
|
||||
|
||||
进入`Settings -> Network`，展开`Outbound requests`，选中`Allow requests to the local network from web hooks and services`
|
||||
|
||||
|
||||
|
||||
## 问题四：GitLab: You are not allowed to force push code to a protected branch on this project
|
||||
|
||||
强制上传代码到`Gitlab`仓库的`dev`分支出错，提示如下：
|
||||
|
||||
```
|
||||
GitLab: You are not allowed to force push code to a protected branch on this project
|
||||
```
|
||||
|
||||
参考：[解决 GitLab: You are not allowed to force push code to a protected branch on this project问题](https://blog.csdn.net/mqdxiaoxiao/article/details/95794053)
|
||||
|
||||
是由于分支保护的原因，需要进入仓库`setting -> Repository -> Protected Branches`
|
||||
|
||||
|
||||
|
||||
允许`dev`分支能够强制推送
|
||||
|
||||
## 问题五：unicorn出错
|
||||
|
||||
### 问题描述
|
||||
|
||||
通过`docker`部署`gitlab`一段时间后，突然出现`502`错误
|
||||
|
||||
查看容器状态，显示不健康
|
||||
|
||||
```
|
||||
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
|
||||
89481faa2ed1 gitlab/gitlab-ce:latest "/assets/wrapper" 2 weeks ago Up 7 hours (unhealthy)
|
||||
```
|
||||
|
||||
浏览容器日志，发现如下错误：
|
||||
|
||||
```
|
||||
==> /var/log/gitlab/unicorn/unicorn_stdout.log <==
|
||||
bundler: failed to load command: unicorn (/opt/gitlab/embedded/bin/unicorn)

||||

|
||||
```
|
||||
|
||||
### 问题解析
|
||||
|
||||
看样子是`unicorn`的问题，参考：
|
||||
|
||||
[gitlab服务器502恢复过程](https://blog.csdn.net/zhouchuan152/article/details/95871798)
|
||||
|
||||
[gitlab docker Web界面打开反应迟钝的解决办法](https://blog.csdn.net/happyfreeangel/article/details/88653846)
|
||||
|
||||
进入容器内部，查看`unicorn`状态
|
||||
|
||||
```
|
||||
$ docker exec -it xxxx bash
|
||||
# gitlab-ctl tail unicorn
|
||||
```
|
||||
|
||||
发现每次`unicorn`显示的`PID`都不同，修改`/etc/gitlab/gitlab.rb`，添加
|
||||
|
||||
```
|
||||
unicorn['listen'] = 'localhost'
|
||||
unicorn['port'] = 8999
|
||||
```
|
||||
|
||||
更新并重启后，`gitlab`服务恢复正常
|
||||
|
||||
```
|
||||
# gitlab-ctl reconfigure
|
||||
# gitlab-ctl restart
|
||||
```
|
||||
|
||||
## 问题六：版本更新后database出错
|
||||
|
||||
### 问题描述
|
||||
|
||||
拉取了最新的`Docker Gitlab`镜像，部署时发现了如下错误：
|
||||
|
||||
```
|
||||

|
||||
```
|
||||
|
||||
### 问题解决
|
||||
|
||||
在网上查了一些资料，说是新旧版本的配置格式不一致，需要删除之前的配置数据。幸好在本地保存了之前使用的镜像，打包该镜像后上传到服务器重新加载即可
|
||||
|
||||
## 问题七：Prometheus吃磁盘空间
|
||||
|
||||
|
||||
在云服务器上部署`Gitlab`，今天发现无法登录了。登上云服务器后发现磁盘容量没有了，通过查找发现`Prometheus`目录下占据了`30GB`的空间（总共`50GB`）
|
||||
|
||||
参考：
|
||||
|
||||
[Monitoring GitLab with Prometheus](https://docs.gitlab.com/ee/administration/monitoring/prometheus/)
|
||||
|
||||
[Prometheus eats disk space in /var/opt/gitlab/prometheus/data](https://gitlab.com/gitlab-org/omnibus-gitlab/-/issues/4166)
|
||||
|
||||
[GitLab 官方镜像内部集成 Prometheus 历史数据过大的问题处理](https://lakelight.net/2020/03/24/GitLab-Prometheus-clean.html)
|
||||
|
||||
`Prometheus`是一个监控服务，会保存历史监控数据，下面尝试关闭该服务并删除之前的数据（在`Docker Gitlab`上操作）
|
||||
|
||||
1. 修改配置文件`/srv/gitlab/config/gitlab.rb`，添加
|
||||
|
||||
```
|
||||
prometheus_monitoring['enable'] = false
|
||||
```
|
||||
|
||||
2. 关闭`gitlab`并删除`/srv/gitlab/data/prometheus`文件夹数据
|
||||
|
||||
3. 重启`gitlab`，问题解决
|
||||
|
||||
## 问题八：Access deined: You do not have permission push to this repository
|
||||
|
||||
在gitee上新建了一个账户，在上面新建一个仓库，将其ssh链接设置到本地已存在的仓库上，想要把本地仓库推送到远程仓库，出现如下错误：
|
||||
|
||||
```
|
||||
$ git push origin master
|
||||
Access deined: You do not have permission push to this repository
|
||||
fatal: 无法读取远程仓库。
|
||||
|
||||
请确认您有正确的访问权限并且仓库存在。
|
||||
```
|
||||
|
||||
其原因在于本地新建了两个`ssh`密钥，设置在`gitee`的不同账户上，ssh使用之前的密钥读取gitee远程仓库，导致出错。参考[如何使用特定的SSH Key提交GIT](https://www.jianshu.com/p/82aa1678411e)
|
||||
|
||||
在`~/.ssh/config`文件上添加如下内容
|
||||
|
||||
```
|
||||
Host gitee.com
|
||||
HostName gitee.com
|
||||
User git
|
||||
IdentityFile 私钥文件路径
|
||||
IdentitiesOnly yes
|
||||
```
|
||||
|
||||
重新提交即可
