系统：CentOS 8.2
工具：GitLab 社区版
官网：about.gitlab.com/
1.备轿
- 安装postfix用来发送邮件
yum install postfix
curl -s https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash
- 设置系统编码
vi ~/.bashrc
export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
export LANGUAGE=en_US.UTF-8
使用source ~/.bashrc
- 安装GitLab
sudo yum install -y gitlab-ce
- 安装完成后，配置(
vi /etc/gitlab/gitlab.rb)外网访问地址等
external_url 'http://101.37.245.158:8888'
nginx['listen_port'] = 8888
puma['listen'] = '101.37.245.158'
puma['port'] = 8889
puma['socket'] = '/var/opt/gitlab/gitlab-rails/sockets/gitlab.socket'
puma['somaxconn'] = 1024
puma['pidfile'] = '/opt/gitlab/var/puma/puma.pid'
puma['state_path'] = '/opt/gitlab/var/puma/puma.state'
gitlab_workhorse['auth_backend'] = "http://101.37.245.158:8889"
说明：gitlab.rb中没放开的配置，说明它即是默认配置
- 启动
gitlab-ctl reconfigure
gitlab-ctl start
运行后，启动服务如下：
ok: run: alertmanager: (pid 2211) 17s
ok: run: gitaly: (pid 2235) 1s
ok: run: gitlab-exporter: (pid 2248) 0s

- 系统内存、CPU配置跟不上了，欲放弃？ 配置使用swap分区来减少内存消耗

注意，在新版GitLab中，已使用puma取代unicorn
偶遇
- 运行configure命令报错
execute[/opt/gitlab/embedded/bin/initdb -D /var/opt/gitlab/postgresql/data -E UTF8] (postgresql::enable line 75) had an error: Mixlib::ShellOut::ShellCommandFailed: Expected process to exit with [0], but received '1'
---- Begin output of /opt/gitlab/embedded/bin/initdb -D /var/opt/gitlab/postgresql/data -E UTF8 ----
STDOUT: The files belonging to this database system will be owned by user "gitlab-psql".
This user must also own the server process.
STDERR: initdb: error: invalid locale settings; check LANG and LC_* environment variables
---- End output of /opt/gitlab/embedded/bin/initdb -D /var/opt/gitlab/postgresql/data -E UTF8 ----
Ran /opt/gitlab/embedded/bin/initdb -D /var/opt/gitlab/postgresql/data -E UTF8 returned 1
这是由于系统编码问题造成的，解决方法如下：
export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
export LANGUAGE=en_US.UTF-8
- 打开http://101.37.245.158:8888/,提示502错误
Whoops, GitLab is taking too much time to respond.
查询实时日志发现(在访问前运行命令
gitlab-ctl tail)
{"correlation_id":"01EVZZVSEVE7NX8XEHRMXX4NWF","duration_ms":0,"error":"badgateway: failed to receive response: dial unix /var/opt/gitlab/gitlab-rails/sockets/gitlab.socket: connect: connection refused","level":"error","method":"GET","msg":"error","time":"2021-01-14T16:23:18+08:00","uri":"/-/metrics"}
在/etc/gitlab/gitlab.rb中配置如下即可:
gitlab_workhorse['auth_backend'] = "http://101.37.245.158:8888"
- gitlab-shell自动检查失败
gitlab-shell self-check failed
Try fixing it:
Make sure GitLab is running;
Check the gitlab-shell configuration file:
sudo -u git -H editor /opt/gitlab/embedded/service/gitlab-shell/config.yml
Please fix the error above and rerun the checks.
- 400 Bad Request Request Header Or Cookie Too Large puma['port']和gitlab_workhorse['auth_backend']对应的端口号不能跟external_url对应的端口号一致，修改为不同的即可
/var/opt/gitlab/nginx/conf/nginx.conf
