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
0.简介
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
如下：
[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 Preparing... ################################# [100%] Updating / installing... 1:gitlab-ce-10.0.0-ce.0.el6 ################################# [100%] 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
[root@localhost ~]# gitlab-ctl status run: gitaly: (pid 8876) 425s; run: log: (pid 713) 922s run: gitlab-monitor: (pid 8881) 425s; run: log: (pid 683) 924s run: gitlab-workhorse: (pid 8884) 424s; run: log: (pid 676) 924s run: logrotate: (pid 8895) 423s; run: log: (pid 670) 924s run: nginx: (pid 10608) 15s; run: log: (pid 669) 924s run: node-exporter: (pid 8903) 423s; run: log: (pid 681) 924s run: postgres-exporter: (pid 8910) 422s; run: log: (pid 711) 922s run: postgresql: (pid 8918) 421s; run: log: (pid 701) 923s run: prometheus: (pid 10620) 14s; run: log: (pid 674) 924s run: redis: (pid 8931) 420s; run: log: (pid 700) 923s run: redis-exporter: (pid 8934) 420s; run: log: (pid 702) 923s run: sidekiq: (pid 10596) 15s; run: log: (pid 704) 923s 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 0.0.0.0:* LISTEN off (0.00/0/0) tcp 0 0 127.0.0.1:8080 127.0.0.1:58594 TIME_WAIT timewait (35.76/0/0) tcp 0 0 127.0.0.1:8080 127.0.0.1:58608 TIME_WAIT timewait (42.49/0/0) tcp 0 0 127.0.0.1:8080 127.0.0.1:58570 TIME_WAIT timewait (23.64/0/0) 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 <== 2020-09-13_14:07:03.59922 2020/09/13 10:07:02 [emerg] 12265#0: bind() to 0.0.0.0:8080 failed (98: Address already in use) 2020-09-13_14:07:04.10335 2020/09/13 10:07:02 [emerg] 12265#0: bind() to 0.0.0.0:8080 failed (98: Address already in use) 2020-09-13_14:07:04.61290 2020/09/13 10:07:02 [emerg] 12265#0: bind() to 0.0.0.0:8080 failed (98: Address already in use) 2020-09-13_14:07:05.12143 2020/09/13 10:07:02 [emerg] 12265#0: still could not bind()
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" 2020-09-13_14:14:06.12122 2020/09/13 10:14:06 error: keywatcher: dial unix /var/opt/gitlab/redis/redis.socket: connect: no such file or directory 2020-09-13_14:16:47.33884 time="2020-09-13T10:16:47-04:00" level=info msg="Error running query on database: pg_vacuum_analyze dial unix /var/opt/gitlab/postgresql/.s.PGSQL.5432: connect: no such file or directory " source="postgres_exporter.go:919" 2020-09-13_14:16:47.33891 time="2020-09-13T10:16:47-04:00" level=info msg="Error running query on database: pg_replication dial unix /var/opt/gitlab/postgresql/.s.PGSQL.5432: connect: no such file or directory " source="postgres_exporter.go:919"
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 └── repositories └── root └── ssmTemplate.git ├── config ├── description ├── HEAD ├── hooks -> /opt/gitlab/embedded/service/gitlab-shell/hooks ├── hooks.old.1600008315 │ ├── applypatch-msg.sample │ ├── commit-msg.sample │ ├── post-update.sample
........
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

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。
