# Troubleshooting
|
||
|
|
|
||
|
|
This is to troubleshoot https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/245
|
||
|
|
But it might contain useful commands for other cases as well.
|
||
|
|
|
||
|
|
The configuration to add the postgres log in vim is:
|
||
|
|
postgresql['log_directory'] = '/var/log/gitlab/postgresql'
|
||
|
|
|
||
|
|
# Commands
|
||
|
|
|
||
|
|
```bash
|
||
|
|
sudo docker build --tag gitlab_image docker/
|
||
|
|
|
||
|
|
sudo docker rm -f gitlab_app
|
||
|
|
sudo docker rm -f gitlab_data
|
||
|
|
|
||
|
|
sudo docker run --name gitlab_data gitlab_image /bin/true
|
||
|
|
|
||
|
|
sudo docker run -ti --rm --volumes-from gitlab_data ubuntu apt-get update && sudo apt-get install -y vim && sudo vim /etc/gitlab/gitlab.rb
|
||
|
|
|
||
|
|
sudo docker run --detach --name gitlab_app --publish 8080:80 --publish 2222:22 --volumes-from gitlab_data gitlab_image
|
||
|
|
|
||
|
|
sudo docker run -t --rm --volumes-from gitlab_data ubuntu tail -f /var/log/gitlab/reconfigure.log
|
||
|
|
|
||
|
|
sudo docker run -t --rm --volumes-from gitlab_data ubuntu tail -f /var/log/gitlab/postgresql/current
|
||
|
|
|
||
|
|
sudo docker run -t --rm --volumes-from gitlab_data ubuntu cat /var/opt/gitlab/postgresql/data/postgresql.conf | grep shared_buffers
|
||
|
|
|
||
|
|
sudo docker run -t --rm --volumes-from gitlab_data ubuntu cat /etc/gitlab/gitlab.rb
|
||
|
|
```
|
||
|
|
|
||
|
|
# Interactively
|
||
|
|
|
||
|
|
```bash
|
||
|
|
# First start a GitLab container without starting GitLab
|
||
|
|
# This is almost the same as starting the GitLab container except:
|
||
|
|
# - we run interactively (-t -i)
|
||
|
|
# - we define TERM=linux because it allows to use arrow keys in vi (!!!)
|
||
|
|
# - we choose another startup command (bash)
|
||
|
|
sudo docker run -ti -e TERM=linux --name gitlab_app --publish 8080:80 --publish 2222:22 --volumes-from gitlab_data gitlab_image bash
|
||
|
|
|
||
|
|
# Configure GitLab to redirect PostgreSQL logs
|
||
|
|
echo "postgresql['log_directory'] = '/var/log/gitlab/postgresql'" >> /etc/gitlab/gitlab.rb
|
||
|
|
|
||
|
|
# Prevent Postgres from allocating 25% of total memory
|
||
|
|
echo "postgresql['shared_buffers'] = '1MB'" >> /etc/gitlab/gitlab.rb
|
||
|
|
|
||
|
|
# You can now start GitLab manually from Bash (in the background)
|
||
|
|
# Maybe the command below is still missing something to run in the background
|
||
|
|
gitlab-ctl reconfigure > /var/log/gitlab/reconfigure.log & /opt/gitlab/embedded/bin/runsvdir-start &
|
||
|
|
|
||
|
|
# Inspect PostgreSQL config
|
||
|
|
cat /var/opt/gitlab/postgresql/data/postgresql.conf | grep shared_buffers
|
||
|
|
|
||
|
|
# And tail the logs (PostgreSQL log may not exist immediately)
|
||
|
|
tail -f /var/log/gitlab/reconfigure.log /var/log/gitlab/postgresql/current
|
||
|
|
|
||
|
|
# And get the memory
|
||
|
|
cat /proc/meminfo
|
||
|
|
head /proc/sys/kernel/shmmax /proc/sys/kernel/shmall
|
||
|

free -m
