安裝好GitLab，開(kāi)啟服務(wù)，發(fā)現(xiàn)有502錯(cuò)誤。這是開(kāi)始尋找解決辦法，各種百度。?
1.找到/var/log/gitlab/nginx中的錯(cuò)誤日志文件，發(fā)現(xiàn)有如下錯(cuò)誤/var/opt/gitlab/gitlab-rails/sockets/gitlab.socket failed (2: No such file or directory)，然后用 nc命令創(chuàng)建了這個(gè)socket文件，最終權(quán)限設(shè)為srwxrwxrwx，用戶和組設(shè)置為git:git，但發(fā)現(xiàn)這個(gè)方法行不通。
2.這時(shí)我跑到GitLab的官網(wǎng)去尋找解決辦法，https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md?
ctrl+f 502 找到官方教程中說(shuō)502出現(xiàn)的問(wèn)題
Note that on a single-core server it may take up to a minute to restart Unicorn and Sidekiq. Your GitLab instance will give a 502 error until Unicorn is up again.
It is also possible to start, stop or restart individual components.
sudo gitlab-ctl restart sidekiq?
Unicorn supports zero-downtime reloads. These can be triggered as follows:
sudo gitlab-ctl hup unicorn?
Note that you cannot use a Unicorn reload to update the Ruby runtime.
嘗試用上面兩個(gè)命令解決，發(fā)現(xiàn)沒(méi)有用。?
這時(shí)我怒了，不斷的輸入gitlab-ctl status,發(fā)現(xiàn)unicorn的pid一直在變大。而其他幾個(gè)服務(wù)的pid沒(méi)有變化。
3.這時(shí)差不多找到了問(wèn)題的所在了，應(yīng)該就是unicorn的問(wèn)題。然后看官方教程，可以使用gitlab-ctl tail unicorn?來(lái)跟蹤unicorn的狀態(tài)，這時(shí)候悲催的發(fā)現(xiàn)原來(lái)時(shí)權(quán)限不夠，chmod -R 777?/var/log/gitlab
?
?
502 Whoops, GitLab is taking too much time to respond。經(jīng)搜索梳理網(wǎng)上幾篇相同問(wèn)題的解決方案，歸納原因可能如下：
1、unicorn原8080默認(rèn)端口被容器中別的進(jìn)程已經(jīng)占用，必須調(diào)整為沒(méi)用過(guò)的
2、gitlab的timeout設(shè)置過(guò)小，默認(rèn)為60
從這兩個(gè)原因著手，開(kāi)始調(diào)整配置：
1、使用以下命令編輯gitlab配置文件：
sudo docker exec -it gitlab vim /etc/gitlab/gitlab.rb
經(jīng)試驗(yàn)，應(yīng)該修改以下配置項(xiàng)：
unicorn['port'] = 8888
gitlab_workhorse['auth_backend'] = "http://localhost:8888"?
注意：unicorn['port']與gitlab_workhorse['auth_backend']的端口必須相同
2、調(diào)整timout時(shí)長(zhǎng)，從60秒改為90秒
gitlab_rails['webhook_timeout'] = 90?
gitlab_rails['git_timeout']=90
?
以上配置修改完成后，使用以下命令重啟容器：
docker restart gitlab
docker logs gitlab
?
也可以通過(guò)以下命令進(jìn)入容器，查看gitlab啟動(dòng)狀態(tài)和動(dòng)態(tài)日志：
sudo docker exec -it gitlab /bin/bash
cd /usr/bin
gitlab-ctl status
gitlab-ctl tail
?
3、初始鏡像、容器的創(chuàng)建步驟是這樣的：
sudo docker pull gitlab/gitlab-ce
chmod 777 /var/log/gitlab
sudo docker run --detach --hostname devops --publish 443:443 --publish 80:80 --publish 20022:22 --name gitlab --env GITLAB_OMNIBUS_CONFIG="external_url 'http://devops/'; gitlab_rails['lfs_enabled'] = true;" --restart always --volume /home/linyu/gitlab/config:/etc/gitlab --volume /home/linyu/gitlab/logs:/var/log/gitlab --volume /home/linyu/gitlab/data:/var/opt/gitlab gitlab/gitlab-ce:latest
?
4、也可以進(jìn)入容器后，根據(jù)容器創(chuàng)建時(shí)映射的--volume目錄，在里面修改配置，然后重啟gitlab：
gitlab-ctl reconfigure
gitlab-ctl retart
gitlab-ctl status
gitlab-ctl tail
?
