Gitlab快速部署及日常维护（社区版RPM包方式安装）_51CTO博客_gitlab社区版使用教程
本文主要记录2023/11/9在Centos7上排查Gitlab服务停止的操作过程，以及过程中问题的处理。
连接服务器发现内存只用了半G，难道退出终端后gitlab服务就自动关闭了吗
查看状态，服务已经停止
[root@gitlab gitlab]# gitlab-ctl status
fail: alertmanager: runsv not running
fail: gitaly: runsv not running
fail: gitlab-exporter: runsv not running
fail: gitlab-kas: runsv not running
fail: gitlab-workhorse: runsv not running
fail: logrotate: runsv not running
fail: nginx: runsv not running
fail: node-exporter: runsv not running
fail: postgres-exporter: runsv not running
fail: postgresql: runsv not running
fail: prometheus: runsv not running
fail: puma: runsv not running
fail: redis: runsv not running
fail: redis-exporter: runsv not running
fail: sidekiq: runsv not running
[root@gitlab gitlab]#
先去看看日志吧
gitlab常用的默认安装目录
gitlab组件日志路径：/var/log/gitlab
gitlab配置路径：/etc/gitlab/ 路径下有gitlab.rb配置文件
应用代码和组件依赖程序：/opt/gitlab
各个组件存储路径： /var/opt/gitlab/
仓库默认存储路径 /var/opt/gitlab/git-data/repositories
版本文件备份路径：/var/opt/gitlab/backups/
nginx安装路径：/var/opt/gitlab/nginx/
redis安装路径：/var/opt/gitlab/redis
[root@gitlab etc]# cd /var/log/gitlab/
[root@gitlab gitlab]# ll

判断大概在退出终端90分钟后，gitlab服务停止

因为现在还在学习阶段，不求甚解，以跑通gitlab的CI/CD为先。先启动gitlab服务。
[root@gitlab gitlab]# systemctl enable gitlab-runsvdir.service
[root@gitlab gitlab]# gitlab-ctl restart
fail: alertmanager: runsv not running
fail: gitaly: runsv not running
fail: gitlab-exporter: runsv not running
fail: gitlab-kas: runsv not running
fail: gitlab-workhorse: runsv not running
fail: logrotate: runsv not running
fail: nginx: runsv not running
fail: node-exporter: runsv not running
fail: postgres-exporter: runsv not running
fail: postgresql: runsv not running
fail: prometheus: runsv not running
fail: puma: runsv not running
fail: redis: runsv not running
fail: redis-exporter: runsv not running
fail: sidekiq: runsv not running启动失败，看到第一个信息fail: alertmanager: runsv not running，需要启动gitlab运行服务目录(runsvdir)
[root@gitlab gitlab]# systemctl start gitlab-runsvdir
[root@gitlab gitlab]# gitlab-ctl start

run: sidekiq: (pid 5345) 53s; run: log: (pid 5344) 53s埋下个疑问：为啥gitlab-ctl restart命令不能，而systemctl start gitlab-runsvdir命令可以启动
Gitlab服务的启停管理
启动服务： gitlab-ctl start
停止服务： gitlab-ctl stop
重启服务： gitlab-ctl restart
查看状态： gitlab-ctl status
Gitlab的supervisor方式启动服务
服务启动命令： systemctl start gitlab-runsvdir.service
服务停止命令： systemctl stop gitlab-runsvdir.service
服务重启命令： systemctl restart gitlab-runsvdir.service
服务开机启动命令： systemctl enable gitlab-runsvdir.service
取消开机启动命令： systemctl disable gitlab-runsvdir.service
服务查看命令： systemctl list-unit-files
Gitlab服务日志查看：/usr/bin/gitlab-ctl tail #可以查看到gitlab所有插件的日志情况文章来源：https://www.toymoban.com/news/detail-782325.html
