Running MariaDB from the Source Directory

You can run mysqld directly from the source directory (without doing make install).

Starting mysqld after build on Windows

On Windows, data directory is produced during the build The simplest way to start database from the command line is

1. Go to the directory where mysqld.exe is located (subdirectory sql\Debug or sql\Relwithdebinfo of the build directory)

2. From here, execute

mysqld.exe --datadir=..\data --console

As usual, you can pass another mysqld parameters on the command line, or store the in the configuraton file my.ini and pass --defaults-file=path\to\my.ini

Starting mysqld after build on Unix

Copy the following to your '~/.my.cnf' file.

There are two lines you have to edit: 'data=' and 'language='. Be sure to change them to match your environment.

# Example mysql config file.
# You can copy this to one of:
# /etc/my.cnf to set global options,
# /mysql-data-dir/my.cnf to get server specific options or
# ~/my.cnf for user specific options.
# 
# One can use all long options that the program supports.
# Run the program with --help to get a list of available options

# This will be passed to all mysql clients
[client]
#password=my_password
#port=3306
#socket=/tmp/mysql.sock

# Here is entries for some specific programs
# The following values assume you have at least 32M ram

# The MySQL server
[mysqld]
#port=3306
#socket=/tmp/mysql.sock
skip-locking
temp-pool
set-variable  = key_buffer=16M
set-variable  = thread_cache=4
loose-innodb_data_file_path = ibdata1:1000M
loose-mutex-deadlock-detector
gdb

######### Fix the two following paths

# Where you want to have your database
data=/path/to/data/dir

# Where you have your mysql/MariaDB source + sql/share/english
language=/path/to/src/dir/sql/share/english

[mysqldump]
quick
set-variable = max_allowed_packet=16M

[mysql]
no-auto-rehash

[myisamchk]
set-variable= key_buffer=128M

With the above file in place, go to your MariaDB source directory and execute:

./scripts/mysql_install_db --srcdir=$PWD --datadir=/path/to/data/dir

Above '$PWD' is the environment variable that points to your current directory.

Now you can start mysqld in the debugger:

cd sql
ddd mysqld &

Or start mysqld on its own:

cd sql
./mysqld &

After starting up mysqld using one of the above methods (with the debugger or without), launch the client (as root if you don't have any users setup yet).

../client/mysql

Using a storage engine plugin

The simplest case is to compile the storage engine into MariadB:

configure --with-plugin-<plugin_name>

Another option is to point mysqld to the storage engine directory:

mysqld --plugin-dir=source-dir-path/storage/connect/.libs
