# 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 ![](./imgs/8080.png) ### 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 ... ... # curl localhost:8801 You are being redirected. ``` ## 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 ![](./imgs/configure-gitlab.png) 进入`Settings -> Network`，展开`Outbound requests`，选中`Allow requests to the local network from web hooks and services` ![](./imgs/allow-local-request.png) ## 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` ![](./imgs/protected-branches.png) 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) ==> /var/log/gitlab/unicorn/unicorn_stderr.log <== ArgumentError: Already running on PID:460 (or pid=/opt/gitlab/var/unicorn/unicorn.pid is stale) /opt/gitlab/embedded/lib/ruby/gems/2.6.0/gems/unicorn-5.4.1/lib/unicorn/http_server.rb:205:in `pid=' /opt/gitlab/embedded/lib/ruby/gems/2.6.0/gems/unicorn-5.4.1/lib/unicorn/http_server.rb:137:in `start' /opt/gitlab/embedded/lib/ruby/gems/2.6.0/gems/unicorn-5.4.1/bin/unicorn:126:in `' /opt/gitlab/embedded/bin/unicorn:23:in `load' /opt/gitlab/embedded/bin/unicorn:23:in `' ==> /var/log/gitlab/unicorn/current <== 2019-12-18_12:27:47.34406 failed to start a new unicorn master 2019-12-18_12:27:47.35882 starting new unicorn master 2019-12-18_12:27:47.91735 master failed to start, check stderr log for details ``` ### 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： ``` gitlab | System Info: gitlab | ------------ gitlab | chef_version=14.14.29 gitlab | platform=ubuntu gitlab | platform_version=16.04 gitlab | ruby=ruby 2.6.6p146 (2020-03-31 revision 67876) [x86_64-linux] gitlab | program_name=/opt/gitlab/embedded/bin/chef-client gitlab | executable=/opt/gitlab/embedded/bin/chef-client gitlab | gitlab | gitlab | Running handlers: gitlab | There was an error running gitlab-ctl reconfigure: gitlab | gitlab | bash[migrate gitlab-rails database] (gitlab::database_migrations line 55) had an error: Mixlib::ShellOut::ShellCommandFailed: Expected process to exit with [0], but received '1' gitlab | ---- Begin output of "bash" "/tmp/chef-script20200618-23-sfpkhu" ---- gitlab | STDOUT: rake aborted! gitlab | PG::ConnectionBad: could not connect to server: No such file or directory gitlab | Is the server running locally and accepting gitlab | connections on Unix domain socket "/var/opt/gitlab/postgresql/.s.PGSQL.5432"? gitlab | /opt/gitlab/embedded/service/gitlab-rails/lib/tasks/gitlab/db.rake:48:in `block (3 levels) in ' gitlab | /opt/gitlab/embedded/bin/bundle:23:in `load' gitlab | /opt/gitlab/embedded/bin/bundle:23:in `
