Install Gitea Git Service on Ubuntu 18.04

Gitea is a free, open source and self-hosted version control system alternative to GitHub and GitLab. It is simple, easy, robuts, scalable and a great alternative to other git services. All source code is available under the MIT License on GitHub. Gitea has low minimal requirements (1 CPU core and 1GB RAM), so it can run on an inexpensive Raspberry Pi.

You can also compile Gitea for Windows, macOS, Linux, ARM, etc. Gitea provides lots of features such as, Low resource usage, Multiple database support, free and open source, Multiple OS support, etc.

In this tutorial, we will learn how to install and configure Gitea Git Service on Ubuntu 18.04 server.

Official git repository of Gitea: https://github.com/go-gitea/gitea/

First of all install Ubuntu 18.04. on Your virtual or physical server. After that update and upgrade your system to latest version:

sudo apt-get update
sudo apt-get upgrade

First, you will need to download the latest version of Gitea binary from Git repository. All versions of Gitea You can see here: https://github.com/go-gitea/gitea/releases/. You can download it with the following command:

wget https://github.com/go-gitea/gitea/releases/download/v1.10.3/gitea-1.10.3-linux-amd64

Next, copy the downloaded file to /usr/local/bin/ directory and give necessary permissions:

cp gitea-1.10.3-linux-amd64 /usr/local/bin/gitea
chmod 755 /usr/local/bin/gitea

Next, create a system user for Gitea with the following command:

adduser --system --shell /bin/bash --group  --disabled-password --home /home/gitea gitea

Next, create a directory structure for Gitea with the following command:

mkdir -p /etc/gitea /var/lib/gitea/{custom,data,indexers,public,log}
chown gitea:gitea /etc/gitea /var/lib/gitea/{custom,data,indexers,public,log}
chmod 750 /var/lib/gitea/{data,indexers,log}
chmod 770 /etc/gitea

Create Systemd Service file for Gitea

Next, you will need to create a systemd service file to manage Gitea service. You can create it with the following command:

nano /etc/systemd/system/gitea.service

Add the following lines:

[Unit]
Description=Gitea
After=syslog.target
After=network.target
After=mysql.service

[Service]
RestartSec=2s
Type=simple
User=root
Group=root
WorkingDirectory=/var/lib/gitea/
ExecStart=/usr/local/bin/gitea web -c /etc/gitea/app.ini
Restart=always
Environment=USER=root HOME=/home/git GITEA_WORK_DIR=/var/lib/gitea

[Install]
WantedBy=multi-user.target

Save and close the file. Then, reload systemd and start Gitea service with the following command:

systemctl start gitea

You can check the status of Gitea service with the following command:

systemctl status gitea

Next, enable Gitea service to start at boot time with the following command:

systemctl enable gitea

Allow SSH root login on Ubuntu 18.04

By default Ubuntu 18.04 installation comes with unset root password. To set root password open up terminal and execute the following linux command:

$ sudo passwd
[sudo] password for user: 
Enter new UNIX password: 
Retype new UNIX password: 
passwd: password updated successfully

Edit SSH configuration file: /etc/ssh/sshd_config and set property PermitRootLogin to yes:

Save configuration file and restart ssh service by command:

sudo service ssh restart

Gitlab – create and restore backup

To create backup enter command:

sudo gitlab-rake gitlab:backup:create

First we need to make sure that the backup tar file is in the backup directory described in the gitlab.rb configuration (Default is /var/opt/gitlab/backups). Next, we need gitlab running for restoring backup on ominbus installations. If it’s not up, start with,

sudo gitlab-ctl start

and we need to have services that are connected to database in stopped state,

sudo gitlab-ctl stop unicorn
sudo gitlab-ctl stop sidekiq

Copy files from backup folder (/var/opt/gitlab/backups) to external hard drive, also copy files:

/etc/gitlab/gitlab-secrets.json
/etc/gitlab/gitlab.rb

Now execute the following command to restore the backup on server,

sudo gitlab-rake gitlab:backup:restore BACKUP=1393157476_2018_03_11_9.1.0

here, 1393157476_2018_03_11_9.1.0 is the name of the backup file that will be restored. Once the backup has been restored, we need to restart the gitlab services,

sudo gitlab-ctl restart

We now have successfully restored gitlab from the backup file.

How to view information about ONU on BDCOM OLT

I’ll give you an example of viewing information about ONT (ONU) on EPON OLT BDCOM P3310C, on other models is essentially the same.

Connect to OLT and go into configuration mode:

enable
config

To view the ONU list, use the commands:

show epon onu-information
show epon active-onu
show epon inactive-onu

To view all ONU MAC addresses on interface use command:

show epon onu-information interface EPON 0/1

Example of viewing clients routers MAC addresses on a port or ONU:

show mac address-table interface EPON0/1
show mac address-table interface EPON0/1:5
show mac address-table brief

Viewing the optical power of all ONUs on interface and a specific ONU:

show epon optical-transceiver-diagnosis interface EPON 0/1
show epon interface ePON 0/1:4 onu ctc optical-transceiver-diagnosis

View ONU models and firmware versions:

show epon onu-software-version
show epon onu-software-version interface EPON 0/1

View description and status of interfaces:

show interface brief

ONU ethernet port status and viewing statistics:

show epon interface epON 0/1:1 onu port 1 state
show epon interface epON 0/1:1 onu port 1 statistics
show epon interface epON 0/1:1 onu mac address-table

Also you can see in the saved and active OLT configuration which ONUs are registered:

show configuration
show running-config

ONU reboot example:

epon reboot onu interface ePON 0/1:1
