gitlab部署

安装方式介绍：https://docs.gitlab.com/ee/install/README.html

  • 配置gitlab仓库，用包管理器直接安装，（会自动安装所有依赖组件，官方推荐）
  • helm chart安装，for k8s平台
  • docker方式
  • 从头逐步安装各个组件

此处采用官方推荐的方式，仓库安装

安装依赖

参考文档；https://about.gitlab.com/install/#centos-7

[root@gitlab ~]# yum install -y curl policycoreutils openssh-server openssh-client postfix

配置gitlab的仓库

这里采用清华大学的仓库源，配置仓库地址

vim /etc/yum.repos.d/gitlab-ce.repo

[gitlab-ce]
name=Gitlab CE Repository
baseurl=https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el$releasever/
gpgcheck=0
enabled=1

sudo yum makecache
sudo yum install gitlab-ce

直接安装



[root@gitlab ~]# yum list all |grep gitlab
gitlab-ce.x86_64                         13.6.1-ce.0.el7               gitlab-ce

Complete!

修改配置文件

修改配置文件中，external_url地址，为自己部署主机的ip；

[root@gitlab ~]# vim /etc/gitlab/gitlab.rb 
...
#external_url 'http://gitlab.example.com'
external_url 'http://192.168.80.102'

reconfigure使得配置重新生效；

[root@gitlab ~]# gitlab-ctl reconfigure
...
Running handlers:
Running handlers complete
Chef Infra Client finished, 207/1184 resources updated in 01 minutes 53 seconds

Deprecations:
* sidekiq_cluster['experimental_queue_selector'] has been deprecated since 13.6 and will be removed in 14.0. The experimental_queue_selector option is now called queue_selector.


Notes:
It seems you haven't specified an initial root password while configuring the GitLab instance.
On your first visit to  your GitLab instance, you will be presented with a screen to set a
password for the default admin account with username `root`.


遇到的问题，google查得，可能为vm内存不足导致，加大到3g后可以，最低要求2g
Errno::ENOMEM: Cannot allocate memory - fork(2) gitlab

浏览器登陆

访问的地址，external_url为浏览器里访问的地址；第一次访问，会提示修改管理员密码，**管理员账户，默认为root；**非linux系统的root！

修改后，用root登陆即可；

关闭自动注册

​ 首次登陆会提示open registration问题，如下图示：

image-20201204175805325

​ 下图示：默认的设置，用户通过访问注册url，可以自行注册用户，不安全，应该关闭；将默认选中的2项，取消，点击保存即可；

image-20201204180019185

关闭前：有注册选项，register now；

image-20201206125721722

关闭后：无注册选项；

配置smtp服务

  1. 登陆自己的qq或163邮箱，开启smtp服务，会生成一个授权码，假设为aaa；

  2. 配置本地gitlab的配置文件；

    [root@gitlab ~]# vim /etc/gitlab/gitlab.rb
   
external_url 'http://本地私有gitlab的url' 
gitlab_rails['smtp_enable'] = true  
gitlab_rails['smtp_address'] = "smtp.163.com"  
gitlab_rails['smtp_port'] = 25  
gitlab_rails['smtp_user_name'] = "你注册的公网邮箱"  
gitlab_rails['smtp_password'] = "开启smtp服务时给的授权码"  
gitlab_rails['smtp_domain'] = "163.com"  
gitlab_rails['smtp_authentication'] = :login  
gitlab_rails['smtp_enable_starttls_auto'] = true  
gitlab_rails['gitlab_email_from'] = "你注册的公网邮箱"  
user["git_user_email"] = "你注册的公网邮箱"  
   
# smpt-port不同的邮箱服务商不同，网易163是25

  3. 重新生成配置、重启gitlab

    [root@gitlab ~]# gitlab-ctl reconfigure
[root@gitlab ~]# gitlab-ctl restart

  4. 之后，本地的gitlab就可以借助公网的邮箱服务，发送互联网邮件；

创建普通用户测试邮箱

1、管理员创建普通用户，邮箱填写为公网可达，或公司内部私网可达邮箱地址；

image-20201206132758755

2、此时普通用户，假设为申请了账户的开发人员，通过公网或私网邮箱地址收到了账户创建通知，之后需要点击连接改自己的密码，然后就可以进行登陆；

更改密码会也会收到邮件通知；
