I have used apache/tomcat-mysql-php many years ago. Recently, I need to configure my own local database management system, to manage EHR datasets based on OMOP schema. So, I picked this system up.

The two key config files are httpd.conf in Apache and php.in in PHP. I did not use the mature wamp because I’m not sure which database I would use finally, and I have much more flexibility if I configed by hand. And most importantly, it’s easy.

Step-by-Step configs in windows

Check vs distributions
1. Go to control panel. …
2. Now under Programs click uninstall a program.
3. Now you can see all the list of programs installed in your PC.
4. Now find Microsoft Visual C++ in the list.
5. In the last column you can see the version of the program.

You may need to update/install Visual C++ redistributables to the latest version or at least 2019 version.

Get Apache and config
1. Get 2.4.54 version from https://www.apachelounge.com/download/
2. Extract to C:\Web
3. Config C:\Web\Apache24\conf\httpd.conf a. Define SRVROOT “c:\Web\Apache24” #(Around line 37) b. ServerAdmin admin@localhost #(Around line 218 c. ServerName localhost:80 #(Around line 227) d. Save
4. Check Apache a. Run ‘cmd’ as adminstrator b. in cmd terminal, run
```
1
  C:/Web/Apache24/bin/httpd.exe -S
```
  Something like below: VirtualHost configuration: ServerRoot: “C:/Web/Apache24” Main DocumentRoot: “C:/Web/Apache24/htdocs” Main ErrorLog: “C:/Web/Apache24/logs/error.log” Mutex default: dir=”C:/Web/Apache24/logs/” mechanism=default PidFile: “C:/Web/Apache24/logs/httpd.pid” Define: DUMP_VHOSTS Define: DUMP_RUN_CFG Define: SRVROOT=c:\Web\Apache24
5. Install httpd.exe
```
1
  C:/Web/Apache24/bin/httpd.exe -k install
```
  “Allow Access to Private”
6. Start Apache2.4 Service Run WIndows “Service” and find “Apache2.4”, right click and ‘Start’ Open “Chrome”, and go to “localhost”, should come out “It works”

Get Postgresql If Postgresql is installed. Just ignore this part. Some helpful hints to specify your data directory and register your database to windows ‘Service’:

makdir yourpgsql\data
initdb -D yourpgsql\data -U postgres
pg_ctl register -N "PostgreSQL-x64-15" yourpgsql\data
psql -U postgres

Get and config php
1. Download php8.1.12, extract to C:\web\php-8.1.12
2. Go to C:\web\php-8.1.12, copy “php.ini-development” to “php.ini”
3. Edit C:\web\Apache2.4\config\httpd.conf, appending:

LoadModule php_module "C:\Web\php-8.1.12\php8apache2_4.dll"
AddHandler application/x-httpd-php .php
PHPIniDir "C:\Web\php-8.1.12"
LoadFile "C:\Web\php-8.1.12\libpq.dll"

And Change line 285 to:

    DirectoryIndex index.html index.php

Save,check by runing “C:\Web\Apache24\bin\httpd.exe -S” and restart apache service

Test hello.php
1. write a helloworld.php and save it to C:\web\Apache24\htdocs
2. in your brower, check: “localhost/helloworld.php”, should show conents in your helloworld.php
Config postgresql config php.in,

line763, uncomment

extension_dir = "C:\Web\php-8.1.12\ext"

line937 and line939, uncomment:

extension=pdo_pgsql
extension=pgsql

restart service httpd and test!

-dbconnectsample.php

<?php
$conn = pg_connect("host=localhost port=5432 user=xxx@localhost password=xxxx123 dbname=dbtest");
if (!$conn){
    die("PostgreSQL failed");
}
echo "PostgreSQL connected";
?>

Config for MySQL

Download MySQL

ConfigMySQL

Config my.ini, and put it to C:\Web\mysql-8.0.31-winx64\my.ini

 [mysqld]
 # set basedir to your installation path
 basedir=C:/Web/mysql-8.0.31-winx64
 # set datadir to the location of your data directory
 datadir=C:/Web/mysql-8.0.31-winx64/data
 # set table name case sensitive
 lower_case_table_names=2

Start MySQL

 #Init mysql
 .\mysqld.exe --defaults-file=C:\Web\mysql-8.0.31-winx64\my.ini --initialize --console
 #a password for root will be generated, need to write it down!

 #start MySQL service
 .\mysqld.exe --install MySQL --defaults-file=C:\Web\mysql-8.0.31-winx64\my.ini

Reset root password

#login sql
mysql.exe -u root -passwordgeneratedabove

 ALTER USER 'root'@'localhost' IDENTIFIED BY 'newpassword';
 flush privileges;
 exit;

Import Data

mysql.exe -u root -p -h localhost < C:/Web/Apache24/htdocs/sql/mydb_schema.sql
#Or
mysql.exe -u username -p schemaname -h localhost < C:/Web/Apache24/htdocs/sql/mydb_schema.sql

Some useful MySQL commands:

show databases;
use db;
show tables;
DESCRIBE usertable;
