接wiki 【服务器断电后，重启服务器，gitlab无法访问】https://blog.csdn.net/nobigdeal00/article/details/144280761
最近把不小心把服务器重启，每次重启后，都会出现gitlab无法访问
分析
查看系统正在运行的任务
bash
adminpc@adminpc:~/go_git/scripts$ systemctl list-jobs
JOB UNIT TYPE STATE
177 system-getty.slice start waiting
19 setvtrgb.service start waiting
2 multi-user.target start waiting
161 gitlab-runsvdir.service start waiting
202 systemd-update-utmp-runlevel.service start waiting
1 graphical.target start waiting
200 plymouth-quit-wait.service start running
7 jobs listed.发现gitlab-runsvdir.service状态处于waiting，而前面有个任务plymouth-quit-wait.service一直处于running，阻塞了其他任务的执行
- plymouth-quit-wait.service
plymouth-quit-wait.service 是 systemd 的一个服务单元，与 Plymouth 引导屏幕管理器有关。而Plymouth 是 Linux 系统中用于显示图形化启动和关闭画面的工具，由于服务器没接入显示器，这里可能对Plymouth的正常启动产生了影响，因为 Plymouth 通常依赖于图形输出设备来确认启动画面的显示状态，这里它可能在一直等待图形模式初始化完成
手动将该任务停掉
bash
adminpc@adminpc:~/go_git/scripts$ sudo systemctl stop plymouth-quit-wait.service

修改 GRUB 启动参数，绕过 Plymouth 的图形启动画面，直接文本启动
编辑 /etc/default/grub 文件
bash
sudo vim/etc/default/grub修改 GRUB_CMDLINE_LINUX_DEFAULT，移除 splash 参数（splash参数会启动图形化的启动画面，即开机动画，对学习开发来说，开机动画其实没那么重要）并添加 text
bash
...
# GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX_DEFAULT="quiet text"
...更新 GRUB 配置并重启系统
bash
sudo update-grub
sudo reboot重启系统后，查看gitlab状态，均正常
