 LRR uses a database called `lrr`.  So create this database using MySQL root account.  Open MySQL's prompt using `sudo mysql`.  Create the database using command `CREATE DATABASE lrr;`, and grant all privileges to MySQL user `lrr` using command `GRANT ALL PRIVILEGES ON lrr.* TO 'mnc'@'localhost' WITH GRANT OPTION;`.   If MySQL user mnc does not exist, create it using command `CREATE USER 'mnc'@'localhost' IDENTIFIED BY 'password'`.

 To facilitate data migration, I need to export the 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`, where mnc after -u is MySQL's username, and lrr after -p is the database name.
-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. Do not have lrr_database_dump.txt?  You can use lrr_database.sql in this repo instead.

You can use lrr_database.sql in this repo instead.

 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:

+### Solving the coding problems in the dump file
+
+If the database contains Chinese characters, the dump file (e.g., lrr_database_dump.sql) may contain *weird* characters, e.g., `ç ”ç©¶ç”Ÿ`, so weird that no one can tell their meaning.
+
+We need to correct these abnormal characters before we import them to the new database, so that the PHP program can correctly display Chinese information.
+
+The simplest solution is using the ftfy (fixes text for you) Python package to convert them, as follows:
+
+```
+from ftfy import fix_text
+
+with open('lrr_database_dump.sql') as f:
+    content = f.read()
+
+content2 = fix_text(content)
+with open('lrr_database_dump_sql_fixed.txt', 'w') as f:
+    f.write(content2)
+```
+
+Now, import data using lrr_database_dump_sql_*fixed*.txt.
+
+If you encounter the 'Unknown MySQL server host' problem during import, replace all apostrophes with a space in the dump file.  For example, if a database table field contains *can't*, then the apostrophe between *n* and *t* can cause that problem.
+
+

 Enock, a graduate student here, has made a tutorial about how he deployed LRR to a remote server (http://lanlab.org/course/2021s/spm/PuTTY-Server.txt).

+Increasing session duration
+---------------------------
+
+By default, the session duration in PHP is set to 1,440 seconds (24
+minutes). However, this is not convenient in most software
+systems. Therefore, we may need to increase the duration to allow
+users to have more session time. To increase the session duration, we
+need to edit the variable *session.gc_maxlifetime* in **php.ini**. We
+can increase its default value to whatever we want (e.g., 7200).  On
+Ubuntu, the file is located at */etc/php/7.2/apache2/php.ini*. On
+XAMPP, the file is located at */xampp/php/php.ini*.

+Resetting password
+------------------
+
+We can reset a user's password by directly modifying the MySQL
+database table called `users_table`.  More specifically, we delete
+that user's information from `users_table` so that the user could sign
+up again.  Suppose the user's student number is 201131129138.
+
+To do so, LRR administrator logs in to MySQL using the following
+command: `mysql -u mnc -p`.  Type the correct password to access
+the MySQL database.
+
+After that, issue the following commands in the mysql prompt.
+
+- `use lrr;`
+
+- `delete from users_table where Student_ID="201131129138";`
+
+The first one uses a database called lrr in MySQL.  The second one
+deletes a record from `users_table` where the student number is
+201131129138.
