下载gitlab的RPM包

下载安装：

https://packages.gitlab.com/gitlab/gitlab-ce

ce表示开源

el表示centos   选64位

el6对应CentOS 6

2.创建存放gitlab安装包的目录,并将下载好的gitlab安装包放进去

mkdir /home/soft/gitlab_soft

3.安装PRM包

rpm -ivh gitlab-ce-15.0.5-ce.0.el7.x86_64.rpm

安装成功后显示

Thank you for installing GitLab!
GitLab was unable to detect a valid hostname for your instance.
Please configure a URL for your GitLab instance by setting `external_url`
configuration in /etc/gitlab/gitlab.rb file.
Then, you can start your GitLab instance by running the following command:
  sudo gitlab-ctl reconfigure

For a comprehensive list of configuration options please see the Omnibus GitLab readme
https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md

Help us improve the installation experience, let us know how we did with a 1 minute survey:
https://gitlab.fra1.qualtrics.com/jfe/form/SV_6kVqZANThUQ1bZb?installation=omnibus&release=15-0

4.打开配置文件

vim /etc/gitalb/gitlab.rb
external_url 'http://instance-0ndv0diu'  -- 原来的
external_url 'http://你的IP'  --修改后

此配置在文件最前边的几行，不需要往后翻很多，要留意

5.然后执行 生效配置代码

gitlab-ctl reconfigure

提示以下信息就说明安装成功了

Running handlers:
There was an error running gitlab-ctl reconfigure:

Cannot set unsupported config value eternal_url.

Running handlers complete
Cinc Client failed. 0 resources updated in 06 seconds

6.查看服务状态

gitlab-ctl status

会看到以下信息

Running handlers:
Running handlers complete
Cinc Client finished, 608/1619 resources updated in 07 minutes 14 seconds

Notes:
Default admin account has been configured with following details:
Username: root
Password: You didn't opt-in to print initial root password to STDOUT.
Password stored to /etc/gitlab/initial_root_password. This file will be cleaned up in first reconfigure run after 24 hours.

NOTE: Because these credentials might be present in your log files in plain text, it is highly recommended to reset the passcurity/reset_user_password.html#reset-your-root-password.

看到上面就说明彻底安装成功了

7.gitlab 安装初始化后，默认账户名是root,密码存放在配置文件
查看初始化密码命令：

cat /etc/gitlab/initial_root_password

[root@localhost gitlab]# cat initial_root_password 
# WARNING: This value is valid only in the following conditions
#          1. If provided manually (either via `GITLAB_ROOT_PASSWORD` environment variable or via `gitlab_rails['initial_root_password']` setting in `gitlab.rb`, it was provided before database was seeded for the first time (usually, the first reconfigure run).
#          2. Password hasn't been changed manually, either via UI or via command line.
#
#          If the password shown here doesn't work, you must reset the admin password following https://docs.gitlab.com/ee/security/reset_user_password.html#reset-your-root-password.

Password: Nr/3tNiHy7YvTpn9hknQ/5lGg8kcu+aob1rHsRUQ3hM=

# NOTE: This file will be automatically deleted in the first reconfigure run after 24 hours.

######密码存放在初始化文件里面，但是只存放24小时，登录gitlab要及时更改密码 ，默认用户是root
这个文件将在首次执行reconfigure后24小时自动删除。----切记

8.访问gitlab
直接在浏览器上输入配置文件中的IP就可以了，没有端口

192.168.201.11

9.更改密码：

10.更改完重新登陆就可以了！
