## Hui's steps
|
||||
|
||||
I spent about two hours on installing LRR to a bare, remote Ubuntu server (Ubuntu 20.04 LTS).
|
||||
|
||||
LRR needs Apache and MySQL to run. I followed [How To Install Linux, Apache, MySQL, PHP (LAMP) stack on Ubuntu 20.04](https://www.digitalocean.com/community/tutorials/how-to-install-linux-apache-mysql-php-lamp-stack-on-ubuntu-20-04) to set up these server applications.
|
||||
|
||||
LRR uses a database called `lrr`. I need to export existing `lrr` to a plain text file (including many sql commands) and import that text file to the newly created `lrr` database on the new server.
|
||||
The command for exporting the database is `mysqldump -u mnc -p lrr > lrr_database_dump.txt`.
|
||||
The command for importing is `mysql -u mnc -p lrr < lrr_database_dump.txt`. Read [How to Import and Export MySQL Databases in Linux](https://phoenixnap.com/kb/import-and-export-mysql-database) for more detail.
|
||||
|
||||
LRR also needs to store assignment submissions. We store them in a folder called `../../lrr_submission`. Note that `lrr_submission` is two levels above the project folder (where many PHP files reside). I copied this folder from the existing one. I think it is also OK if you create an empty folder.
|
||||
We need to set a proper owner and accessibility for `lrr_submission` using the following two commands:
|
||||
`sudo chown -R www-data:www-data lrr_submission` and `sudo chmod -R g+rw lrr_submission`. Also, remember to change the user name and password in `lrr_submission//KeepItSafe.txt` for the database connection.
|
||||
|
||||
The above steps are preparation work. Now we could clone the LRR's repository to `/var/www/html/`.
|
||||
Rename LRR to lrr. Change the owner of lrr: `sudo chown -R $USER:$USER /var/www/lrr`. Edit apache configure file: `sudo nano /etc/apache2/sites-available/lrr.conf`.
|
||||
|
||||
|
||||
<VirtualHost *:80>
|
||||
ServerName lrr
|
||||
ServerAlias www.lrr.com
|
||||
ServerAdmin webmaster@localhost
|
||||
DocumentRoot /var/www/html/lrr
|
||||
ErrorLog ${APACHE_LOG_DIR}/error.log
|
||||
CustomLog ${APACHE_LOG_DIR}/access.log combined
|
||||
</VirtualHost>
|
||||
|
||||
Enable the site lrr: `sudo a2ensite lrr`. Restart the apache server: `sudo systemctl reload apache2`.
|
||||
Visit the LRR application by entering this URL in a web browser: http://121.4.94.30/.
|
||||
|
||||
|
||||
## Enock's steps
|
||||
|
||||
Enock has made a tutorial about how he deployed LRR to a remote server (http://lanlab.org/course/2021s/spm/PuTTY-Server.txt).

## Frequently Asked Questions
|
||||
|
||||
Check FAQ.md (TBA) for details.
|
||||
|
||||
1. Q: The web application's front page does not show properly, i.e., elements are not well aligned.
|
||||
A: You missed two folders `css` and `font-awesome`. These folders include third-party js or css files and therefore are not included.
|
||||
|
||||
1. Q: What if I do not have any information about the `lrr` database?
|
||||
A: You could use `lrr(1).sql` or `lrr_database.sql`. It seems `lrr(1).sql` is more complete.
