GitLab介绍及实战

1 介绍

Gitlab是依赖于Git的远程代码仓库，类似于GitHub、Gitee,不同的是GitHub、Gitee的公网上代码仓库, Gitlab是可以私有化部署的免费远程代码仓库。

2 部署GitLab

至少内存4G，否则电脑带不起来

ce社区版和ee 企业版区别

CE 比 EE 要少一些服务，EE 需要购买额外服务（自己对自己写的代码，都特别自信，却很有bug，所有提出了code review）。

2.1 安装依赖

# yum install curl policycoreutils openssh-server openssh-client -y

2.2 启动sshd

# systemctl enable sshd
# systemctl start sshd

2.3 安装邮件服务

# yum install postfix
# systemctl enable postfix
# systemctl start postfix

2.3 下载安装gitlab-ce

# curl -sS https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash

# yum install gitlab-ce  -y
It looks like GitLab has not been configured yet; skipping the upgrade script.

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

2.4 修改配置

# vim /etc/gitlab/gitlab.rb

修改：

external_url 'http://xxx.xxx.xxx.xxx'

2.5 配置初始化

# gitlab-ctl reconfigure

2.6 启动

# gitlab-ctl restart

# gitlab-ctl status

2.7 查看密码

cat /etc/gitlab/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: NMo3VK+Lm9HHhhuHVZZI6d7Uvb5cQ9S6nEZr+A4ZD78=

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