简单研究docker下gitlab服务器的安装过程。其实是为了后面研究jenkins自动部署。
其安装也可以用docker安装或者是直接宿主机中安装,参考:
https://about.gitlab.com/install
GitLab 是一个用于仓库管理系统的开源项目,使用Git作为代码管理工具,并在此基础上搭建起来的web服务。可以认为GitLab是免费版的Github,主要功能都差不多。
1. gitlab安装
1.安装相关依赖
sudo yum install -y curl policycoreutils-python openssh-server
sudo systemctl enable sshd
sudo systemctl start sshd
sudo firewall-cmd --permanent --add-service=http
sudo firewall-cmd --permanent --add-service=https
sudo systemctl reload firewalld
2.安装Postfix以发送通知邮件
sudo yum install postfix
sudo systemctl enable postfix
sudo systemctl start postfix
3. 下载rpm包
https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/
4. 下载后上传到linux服务器
rpm -ivh ./gitlab-ce-10.0.0-ce.0.el6.x86_64.rpm
[root@localhost gitlab]# rpm -ivh ./gitlab-ce-10.0.0-ce.0.el6.x86_64.rpm
warning: ./gitlab-ce-10.0.0-ce.0.el6.x86_64.rpm: Header V4 RSA/SHA1 Signature, key ID f27eab47: NOKEY

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
For a comprehensive list of configuration options please see the Omnibus GitLab readme
https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md
5. 修改IP和端口
修改/etc/gitlab/gitlab.rb
vi /etc/gitlab/gitlab.rb
修改IP和端口,注意这个配置在原来存在,需要用 / external_url 查找后修改:
external_url 'http://192.168.1.128:8080'
6. 重新加载配置后重启
gitlab-ctl reconfigure
gitlab-ctl restart
补充:我启动后报错得到如下信息:
查看日志信息:
(1) 查看状态

run: unicorn: (pid 10575) 17s; run: log: (pid 667) 925s
(2) 查看端口:
[root@localhost ~]# netstat -nao|grep 8080

tcp 0 0 127.0.0.1:8080 127.0.0.1:58630 TIME_WAIT timewait (57.46/0/0)
(3)查看日志:
==> /var/log/gitlab/nginx/current <==

发现端口被占用
(4) 解决办法:
停止服务:
gitlab-ctl stop
修改端口:
vi /etc/gitlab/gitlab.rb
下面端口修改为8888
unicorn['port'] = 8888
(5)我在中间还报错:
2020-09-13_14:14:06.12114 2020/09/13 10:14:06 redis: dialing "unix", "/var/opt/gitlab/redis/redis.socket"

解决:赋予权限:
sudo chmod 755 /var/opt/gitlab/postgresql
sudo chmod 755 /var/opt/gitlab/redis
sudo chmod 755 /var/opt/gitlab/
(6) 重新加载以及重启
(7) free查看内存:
[root@localhost postgresql]# free
total used free shared buff/cache available
Mem: 2895200 1086972 1200244 56200 607984 1567808
Swap: 2097148 0 2097148
[root@localhost postgresql]# free
total used free shared buff/cache available
Mem: 2895200 1914688 371976 56420 608536 739832
发现内存在一直减少,应该是gitlab初始化没完成。
(8)等待内存稳定后访问:
2.gitlab简单使用
1. 第一次访问需要设置密码
我将密码简单的设为: qwe123123
2. 登陆
默认账号是root,密码是上面设置的qwe123123
3.这里我们简单的创建一个项目,并且将本地的项目推送到gitlab(简单的操作下)
(1) New->new project (有点类似于github)
(2) windows客户端拉取代码修改之后推送到gitlab

(3)gitlab服务器查看提交记录:
(4) gitlab服务器查看文件存储位置:
默认的仓库存储路径在 /var/opt/gitlab/git-data目录下,仓库存储在子目录repositories里面,可以通过修改/etc/gitlab/gitlab.rb文件中git_data_dirs参数来自定义父目录
[root@localhost postgresql]# tree /var/opt/gitlab/git-data
/var/opt/gitlab/git-data

补充:gitlab相关命令
启动服务:gitlab -ctl start
查看状态:gitlab -ctl status
停掉服务:gitlab -ctl stop
重启服务:gitlab -ctl restart
让配置生效:gitlab -ctl reconfigure
补充:防火墙相关命令

[root@localhost ~]# systemctl stop firewalld.service
[root@localhost ~]# firewall-cmd --state

[root@localhost ~]# systemctl disable firewalld.service

补充:gitlab修改服务器地址
vi /opt/gitlab/embedded/service/gitlab-rails/config/gitlab.yml
修改后重启gitlab即可。
