Docker安装配置Gitlab，以及常见问题解决_docker部署gitlab时仓库地址是乱码

一、文档

• 官方文档

• 参考文档

• 镜像地址

  # 选择社区版
  docker pull gitlab/gitlab-ce
  1
  2

• GitLab CI

  1.CI是Continuous Integration的简称，就是持续集成的意思。

  2.每次提交代码都会自动打包一遍。

二、安装

1.设置环境变量

配置环境变量$GITLAB_HOME ，该变量指向配置，日志和数据文件将驻留的目录。确保目录存在并且已授予适当的权限。

• Linux

  vim /etc/profile
  
  export GITLAB_HOME=/root/software/gitlab
  1
  2
  3

• MacOS

  vi ~/.bash_profile # 用户级 - 【推荐】
  
  export GITLAB_HOME=$HOME/gitlab
  # 配置文件生效
  source ~/.bash_profile

2.创建存储目录

如果遇到问题实在无法启动了，将这三个数据备份，重装即可自动恢复数据

# 创建文件夹
mkdir -p /root/software/gitlab/etc
mkdir -p /root/software/gitlab/log
mkdir -p /root/software/gitlab/data

3.启动容器

# 80(http)、22(ssh)和443(https)
sudo docker run --detach \
  --publish 443:443 --publish 80:80 --publish 22:22 \
  --name gitlab \
  --restart always \
  --volume $GITLAB_HOME/config:/etc/gitlab \
  --volume $GITLAB_HOME/logs:/var/log/gitlab \
  --volume $GITLAB_HOME/data:/var/opt/gitlab \
  --shm-size 256m \
  gitlab/gitlab-ce:latest

# 启动报错执行
# yum update systemd
# service docker restart

• 查看启动日志

  docker logs -f gitlab
  1

4.配置GitLab实例

• 进入容器

  docker exec -it gitlab /bin/bash
  
  # 记录初始密码（该文件将在24小时后的首次重新配置运行中自动删除。）
  cat /etc/gitlab/initial_root_password
  1

• 编辑配置文件

  vi /etc/gitlab/gitlab.rb
  
  external_url 'http://192.168.1.123:80' # GitLab服务器的访问地址
  nginx['listen_port'] = 80 # 监听端口
  gitlab_rails['gitlab_ssh_host'] = '192.168.1.123' # ssh协议地址
  gitlab_rails['gitlab_shell_ssh_port'] = 22 # ssh协议端口

• 重新加载配置

  gitlab-ctl reconfigure
  # 或者重启GitLab ：docker restart gitlab

5.配置邮件服务

QQ邮箱服务器

vi /etc/gitlab/gitlab.rb

gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = "smtp.qq.com"
gitlab_rails['smtp_port'] = 465
gitlab_rails['smtp_user_name'] = "88888888@qq.com"
gitlab_rails['smtp_password'] = "xxxxxxxxx"   # 授权码去掉中间空格
gitlab_rails['smtp_domain'] = "qq.com"
gitlab_rails['smtp_authentication'] = "login"
gitlab_rails['smtp_enable_starttls_auto'] = true
gitlab_rails['smtp_tls'] = true
# gitlab发信人
gitlab_rails['gitlab_email_from'] = '88888888@qq.com'

# 更新设置
gitlab-ctl reconfigure

163邮箱服务器（不推荐）

目前OpenSSL版本不对报错。

vim /etc/gitlab/gitlab.rb

gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = "smtp.163.com"
gitlab_rails['smtp_port'] = 25
gitlab_rails['smtp_user_name'] = "xxxxxxx@163.com"
gitlab_rails['smtp_password'] = "xxxxxx"
gitlab_rails['smtp_domain'] = "163.com"
gitlab_rails['smtp_authentication'] = "login"
gitlab_rails['smtp_enable_starttls_auto'] = true
gitlab_rails['smtp_tls'] = true

#  gitlab发信人
gitlab_rails['gitlab_email_from'] = 'xxxxxxxx@163.com'

# 更新设置
gitlab-ctl reconfigure

# 启动测试

三、访问

四、常见异常

500内部错误

docker restart gitlab

权限问题

docker exec gitlab update-permissions
docker restart gitlab

无法启动

Cannot start service zk: oci runtime error: container_linux.go:235: starting container process caused "process_linux.go:258: applying cgroup configuration for process caused \"Cannot set property TasksAccounting, or unknown property.\""

# 解决方法：
yum update systemd
service docker restart

无法push代码

执行 git push -uf origin main时报错，为了防止肆意提交代码到master，master默认保护状态。

Total 3 (delta 0), reused 0 (delta 0), pack-reused 0
remote: GitLab: You are not allowed to force push code to a protected branch on this project.
To http://192.168.1.123/up/insp-service.git
 ! [remote rejected] main -> main (pre-receive hook declined)
error: failed to push some refs to 'http://192.168.1.123/up/insp-service.git'

解决办法：直接取消保护，公网可以应该可以配置allowed to push。

输错密码后，无法继续

window平台在git clone时，输错密码无法继续。

【控制面板】-> 【用户账户】-> 【凭据管理器】-> 【普通凭据】-> 删除

# 尝试重启，结果直接好了（启动有点慢）
# gitlab-ctl reconfigure
docker restart gitlab

docker exec -it gitlab /bin/bash
# 检查报错原因
gitlab-rake gitlab:check

# 1.查看端口是否占用

# 2.查看是否内存不足

Redis无法连接

docker logs -f --tail 100 gitlab
# systemctl status docker
tail -f /root/software/gitlab/logs/gitlab-rails/production.log

解决：

# find / -name dump.rdb
rm /root/software/gitlab/data/redis/dump.rdb
# 重启
docker restart gitlab

gitlab chown gitlab-redis /var/opt/gitlab/redis/*
