gitlab—2FA双因子认证登录配置

一、2FA配置

Two-Factor Authentication(2FA),一般称双因素认证

1)gitlab配置

2)手机端下载Authenticator

添加账户==>其他账户==>扫描二维码

3)gitlab填入pin code

4)重新登录测试

可以填入pin code或者recovery code(当无法获取pin code时)

参考文档:

二、2FA禁用

2.1、思路分析

进入postgresql数据库,修改user表,将otp_required_for_login  、 require_two_factor_authentication_from_group 这两个字段,都改为false(数据库中用f表示)

2.2、操作步骤

由于我的gitlab使用docker容器起的,需要进入容器中

1)进入docker容器

[root@git ~]# docker ps 
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                       PORTS                                                           NAMES
3694c2292ed0        gitlab/gitlab-ce    "/assets/wrapper"   42 hours ago        Up About an hour (healthy)   0.0.0.0:80->80/tcp, 0.0.0.0:443->443/tcp, 0.0.0.0:222->22/tcp   gitlab
[root@git ~]# docker exec -it gitlab /bin/sh
# 

2)查看/etc/passwd,发现gitlab-psql用户是可以登录的

[root@git ~]# docker exec -it gitlab /bin/sh
# cat /etc/passwd
root:x:0:0:root:/root:/bin/bash
daemon:x:1:1:daemon:/usr/sbin:/usr/sbin/nologin

gitlab-prometheus:x:992:992::/var/opt/gitlab/prometheus:/bin/sh
gitlab-consul:x:991:991::/var/opt/gitlab/consul:/bin/sh

3)查看数据库配置信息

# cat /var/opt/gitlab/gitlab-rails/etc/database.yml
# 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`.

production:
  adapter: postgresql
  encoding: unicode
  collation: 
  database: gitlabhq_production   #要登录的数据库
  pool: 1
  username: "gitlab"
  password: 
  host: "/var/opt/gitlab/postgresql"  #登录主机
  port: 5432
  socket: 
  sslmode: 
  sslcompression: 0
  sslrootcert: 
  sslca: 
  load_balancing: {"hosts":[]}
  prepared_statements: false
  statements_limit: 1000
  fdw: 
#

4)根据上面的配置信息登陆postgresql数据库

# su - gitlab-psql
$ 

5)连接到gitlabhq_production库

$ psql  -h  /var/opt/gitlab/postgresql  -d  gitlabhq_production
psql (10.9)
Type "help" for help.

gitlabhq_production=# 

6)操作数据库

查看数据库:

image

查看多表:

image

查看users表:

gitlabhq_production=# \d users

image

查看users表中用户的关键信息,取4个字段:

gitlabhq_production=# SELECT name,username,otp_required_for_login,two_factor_grace_period, require_two_factor_authentication_from_group   FROM users;

image

修改字段:

gitlabhq_production=# UPDATE users set otp_required_for_login = 'f' WHERE username = 'root';
UPDATE 1

image

7)\q退出数据库,重新登录gitlab,就没要求2FA认证
