I suggest using import folder:
conf/import/char-server.conf:
char_configuration: { sql_connection: { db_hostname: "127.0.0.1" db_port: 3306 db_username: "username" db_password: "password" db_database: "database" } } ^ equivalent to Char_server_ip/char_server_port/etc.. in rA
conf/import/login-server.conf:
login_configuration: { account: { sql_connection: { // equivalent to login_server_ip/login_server_port/etc. db_hostname: "127.0.0.1" db_port: 3306 db_username: "username" db_password: "password" db_database: "database" } ipban: { sql_connection: { // equivalent to ipban_db_ip/ipban_db_port/etc. db_hostname: "127.0.0.1" db_port: 3306 db_username: "username" db_password: "password" db_database: "database" } } } } conf/import/inter-server.conf:
 
inter_configuration: { log: { sql_connection: { // equivalent to log_db_ip/log_db_port/etc. db_hostname: "127.0.0.1" db_port: 3306 db_username: "username" db_password: "password" db_database: "database" } } } conf/import/map-server.conf
map_configuration: { sql_connection: { //equivalent to map_server_ip/map_server_port/etc. db_hostname: "127.0.0.1" db_port: 3306 db_username: "username" db_password: "password" db_database: "database" } }  
 
If you want all servers to use same db username/pass/database, you can instead edit conf/global/sql_connection.conf
sql_connection: { db_hostname: "127.0.0.1" db_port: 3306 db_username: "ragnarok" db_password: "ragnarok" db_database: "ragnarok" //codepage:"" } sql_connection.conf affects all server, and avoids mentioning each credentials seperately.
 
I hope it helped you and this is what you were asking for.
