 # Installation Instructions
 
 
-## Hui steps
+## Hui's steps
 
 I spent about two hours 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.  [How to install and configure PHP](https://ubuntu.com/server/docs/programming-php) is also a good guide.
+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`.  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'`.
+LRR uses a database called `lrr`.  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`.
-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 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.
-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.

-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).
