# 未修gitlab.rb配置文件中nginx配置时这个配置默认配置gitlab自带的nginx端口
external_url 'http://172.17.17.10:81'
#nginx['listen_port'] = nil 修改 8090 默认是注释的去掉前面的#
nginx['listen_port'] = 8090
---修改默认的gitlab 相关端口【也可以不修改】
---修改端口配置
---502异常,默认使用8080端口, 冲突要换
### Advanced settings
puma['listen'] = '127.0.0.1'
puma['port'] = 8081
gitlab-ctl hup unicorn
---重新配置gitlab
gitlab-ctl reconfigure
---重新启动gitlab
gitlab-ctl restart
---访问gitlab
http://IP:8090
---查看默认密码
cat /etc/gitlab/initial_root_password|grep Password
===备份还原 迁移新系统
---要保证新旧服务器上的GitLab版本号一致
---旧服务器升级GitLab
---GitLab不能跨版本升级，需一个一个大版本升级。
yum install -y gitlab-ce-11.11.0-ce.0.el7
yum install -y gitlab-ce
---每一次升级，都要测试GitLab后台系统是否正常，如果不能访问了，则说明本次升级失败，应解决错误或回退版本。
---备份旧服务器的文件
gitlab-rake gitlab:backup:create
---默认将会在 /var/opt/gitlab/backups/ 目录下生成备份文件
---新服务器恢复GitLab
cd /var/opt/gitlab/backups
chomd 777 备份文件编号_gitlab_backup.tar
----停止数据连接服务
gitlab-ctl stop unicorn
gitlab-ctl stop sidekiq
---恢复备份文件到GitLab
gitlab-rake gitlab:backup:restore BACKUP=备份文件编号
---启动GitLab
gitlab-ctl start
---配置ssh key, 因为ssh更加安全
cat /etc/passwd
git:x:991:986::/var/opt/gitlab:/bin/sh
cd /var/opt/gitlab
ssh-keygen -t rsa -C 'ihunter@vip.qq.com' -f ~/.ssh/gitlab-rsa
