版本控制gitlab

版本控制是指对软件开发过程中各种程序代码、配置文件及说明文档等文件变更的管理，是软件配置管理的核心思想之一。

版本控制最主要的功能就是追踪文件的变更。它将什么时候、什么人更改了文件的什么内容等信息忠实地了记录下来。每一次文件的改变，文件的版本号都将增加。除了记录版本变更外，版本控制的另一个重要功能是并行开发。软件开发往往是多人协同作业，版本控制可以有效地解决版本的同步以及不同开发者之间的开发通信问题，提高协同开发的效率。并行开发中最常见的不同版本软件的错误(Bug)修正问题也可以通过版本控制中分支与合并的方法有效地解决。

常用的版本控制工具：

• gitlab
• subversion

部署gitlab

下载gitlab的rpm包：gitlab

// 安装epel源
[root@localhost ~]# yum -y install epel-release

// 关闭防火墙和selinux
[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# systemctl disable firewalld
Removed /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

[root@localhost ~]# vim /etc/selinux/confg
SELINUX=disabled
[root@localhost ~]# setenforce 0

// 安装依赖包
[root@localhost ~]# yum -y install curl openssh-server openssh-clients postfix cronie policycoreutils-python-utils git

// 设置postfix开机自启
[root@localhost src]# systemctl enable --now postfix
Created symlink /etc/systemd/system/multi-user.target.wants/postfix.service → /usr/lib/systemd/system/postfix.service.

[root@localhost ~]# cd /usr/src/

// 下载gitlab包
[root@localhost src]# wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el8/gitlab-ce-14.3.2-ce.0.el8.x86_64.rpm

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:

// 修改配置文件
[root@localhost ~]# vim /etc/gitlab/gitlab.rb 
data-data-retrieval.html
external_url 'http://192.168.91.139'  //替换为自己的ip地址


// 配置gitlab
[root@localhost ~]# gitlab-ctl reconfigure
gitlab Reconfigured!
