需求配置

GitLab官方对服务器配置有一定对要求，比如推荐 4核CPU 和 4G内存

安装

Ubuntu

参考资料：Ubuntu官网安装地址

版本 GitLab 13.12.4-ee

1. 安装配置必要依赖

sudo apt-get update
sudo apt-get install -y curl openssh-server ca-certificates tzdata perl

如果需要发送通知邮件

sudo apt-get install -y postfix

2. 添加gitlab包仓库并安装

curl https://packages.gitlab.com/install/repositories/gitlab/gitlab-ee/script.deb.sh | sudo bash
# 安装
apt-get install gitlab-ee

启动

1. 启动

gitlab-ctl start

2. 查看日志

gitlab-ctl tail

发现有几项服务报错

## [分析] prometheus 端口被占用

==> /var/log/gitlab/prometheus/state <==

==> /var/log/gitlab/prometheus/current <==
2021-06-23_01:20:43.41663 level=info ts=2021-06-23T01:20:43.416Z caller=web.go:532 component=web msg="Start listening for connections" address=localhost:9090
2021-06-23_01:20:43.41702 level=error ts=2021-06-23T01:20:43.416Z caller=main.go:608 msg="Unable to start web listener" err="listen tcp 127.0.0.1:9090: bind: address already in use"


## [nginx] 端口被占用
==> /var/log/gitlab/nginx/error.log <==
2021/06/22 18:48:54 [emerg] 8157#0: invalid port in "*:" of the "listen" directive in /var/opt/gitlab/nginx/conf/gitlab-http.conf:36

==> /var/log/gitlab/nginx/state <==

==> /var/log/gitlab/nginx/current <==
2021-06-23_01:20:41.06646 2021/06/23 09:20:40 [emerg] 28393#0: bind() to 0.0.0.0:80 failed (98: Address already in use)


## [grafana] 端口被占用
==> /var/log/gitlab/grafana/current <==
2021-06-23_01:20:46.39111 failed to open listener on address localhost:3000: listen tcp 127.0.0.1:3000: bind: address already in use

3. 修改配置文件中的相应端口

vi /etc/gitlab/gitlab.rb

#external_url 'GENERATED_EXTERNAL_URL'
external_url 'http://192.168.0.200'

# nginx['listen_port'] = nil
nginx['listen_port'] = 10001

# prometheus['listen_address'] = 'localhost:9090'
prometheus['listen_address'] = 'localhost:10002'

# grafana['http_port'] = 3000
grafana['http_port'] = 10003

当修改 nginx['listen_port'] = 10001 时，执行 gitlab-ctl reconfigure 会同步修改 /var/opt/gitlab/nginx/conf/gitlab-http.conf 的

server {
  listen *:10001;

  server_name 192.168.0.200;
  #...
}

4. 重新加载配置文件并重启服务

gitlab-ctl reconfigure
gitlab-ctl restart

5. 访问页面

访问 http://yourIp:yourNginxPort 登陆即可。可能需要等一会，服务启动需要几秒种时间。

文件路径

# GitLab
/etc/gitlab/gitlab.rb               # GitLab 配置文件
/opt/gitlab                         # GitLab 及所有组件配置

/var/opt/gitlab/postgresql/data     # PostgreSQL 数据目录

# Redis组件
/var/opt/gitlab/redis # Redis 安装目录
/var/log/gitlab/redis # Redis 日志目录

常用命令

gitlab-ctl reconfigure # 重新加载配置项
gitlab-ctl start       # 启动所有 gitlab 组件
gitlab-ctl stop        # 停止所有 gitlab 组件
gitlab-ctl restart     # 重启所有 gitlab 组件
gitlab-ctl status      # 查看服务状态
gitlab-ctl show-config #查看gitlab配置信息
cat /opt/gitlab/embedded/service/gitlab-rails/VERSION # 查看版本号

检查定位问题

1. 查看所有服务状态

gitlab-ctl status

run: sidekiq: (pid 13996) 6s; run: log: (pid 10381) 151554s

2. 定位问题

从服务状态信息中显示数据库 gitlab-workhorse 的状态是 down，即服务停止。检查相关错误日志信息。

gitlab-ctl tail gitlab-workhorse
