This guide covers how to install Hercules on CentOS and other versions of Linux that use yum.

Requirements

• CentOS or an RPM-based Linux that has the yum command
• root access or access to an account that has sudo privileges
• an Internet connection to download install packages

Prerequisites

All of these commands will be typed at the command-line interface.

Install Prerequisites

1. Login to your server via SSH, or if you are already logged into a GUI press Ctrl+Alt+T to open a terminal window.
2. Type the following command (this will install GCC, Make, MySQL, MySQL header files, MySQL Server, PCRE header files, Subversion, and Zlib header files)

   yum install gcc make mysql mysql-devel mysql-server pcre-devel git zlib-devel

3. (Optional) type the following command to install some additional packages:

   yum -y install dos2unix gdb nano screen unzip wget zip

Create a non-root Linux user

By the principle of least privilege, it is recommended you do NOT run Herculesas root.

1. Type the following command to create a non-root Linux account:

   useradd --create-home --shell /bin/bash hercules1234

   --create-home = create the user's home directory

   --shell = sets their login shell to Bash

   hercules1234 = the login name of the new Linux account

   1234 = pick your own random numbers to make the username more unique

2. Set a password for the new user (run this command and follow the prompts):

   passwd hercules1234

Configure MySQL

Set a root password

The default MySQL Server install creates a MySQL user 'root'@'localhost' with NO password. It is recommended you create a password for the root user.

1. Run this command and follow the prompts:

   mysql_secure_installation

2. Login to your MySQL Server as root:

   When prompted, enter your root MySQL password.

   mysql --user=root -p

3. Now your prompt should look like this (the MySQL command prompt):

   mysql> 

   In case your mysql server isn't started, you may have to start it with:

   /etc/init.d/mysqld start 

Create SQL database for Hercules

1. At the MySQL prompt, type this to create a database (replace hercules1234 with the Linux username you created earlier):

   mysql> CREATE DATABASE hercules1234_rag;

2. Create a separate database for logs:

   mysql> CREATE DATABASE hercules1234_log;

Setup a MySQL user for Hercules

1. At the MySQL prompt, type something like this to create a new MySQL user:

   mysql> CREATE USER 'hercules1234'@'localhost' IDENTIFIED BY 'secretpassword';

   hercules1234 = the name of the MySQL user (we named it the same as the Linux user to make it easier to identify)

   localhost = the hostname or IP it will connect from

   secretpassword = the password for this MySQL user

2. Grant privileges to the 'Hercules' MySQL user:

   mysql> GRANT SELECT,INSERT,UPDATE,DELETE ON `hercules1234\_rag`.* TO 'hercules1234'@'localhost';

   mysql> GRANT SELECT,INSERT ON `hercules1234\_log`.* TO 'hercules1234'@'localhost';

   (note the escaped underscore)

Install Hercules

Login as your non-root Linux user

The rest of the setup is done as hercules1234(the Linux user you created in step 2.2)

1. Logout from root SSH (or minimize the window).
2. Login to your server via SSH as the hercules1234Linux user.

Git Clone

To download Hercules, you need to perform a clone from Git (Git) repository. Checking out from a repository creates a working copy of it on your local machine.

A Git is required to perform a clone. Recommended applications are:

• git for Unix systems
• MSysGit And TortoiseGit for Windows systems (Both Required

Unix

For detailed instructions on how to install subversion, please refer to OS specific installation guides.

Type the following to create a Hercules working copy in your home (~) directory

  git clone https://github.com/HerculesWS/Hercules.git ~/Hercules

Windows

Check Obtaining Hercules for info on how to clone in windows

Import MySQL Tables

1. Change directory to the sql-files folder.

   cd trunk/sql-files/

2. Execute these commands:

   When prompted, enter your MySQL root password.

   mysql -u root -prootpassword hercules1234_rag < main.sql

   mysql -u root -prootpassword hercules1234_rag < item_db.sql

   mysql -u root -prootpassword hercules1234_rag < item_db2.sql

   mysql -u root -prootpassword hercules1234_rag < mob_db.sql

   mysql -u root -prootpassword hercules1234_rag < mob_db2.sql

   mysql -u root -prootpassword hercules1234_rag < mob_skill_db.sql

   mysql -u root -prootpassword hercules1234_rag < mob_skill_db2.sql

   mysql -u root -prootpassword hercules1234_log < logs.sql

3. If you are using Renewal you also have to import the following

   mysql -u root -prootpassword hercules1234_log < item_db_re.sql

   mysql -u root -prootpassword hercules1234_log < item_db2_re.sql

   mysql -u root -prootpassword hercules1234_log < mob_db_re.sql

   mysql -u root -prootpassword hercules1234_log < mob_skill_db_re.sql

NOTE: if you want to use different SQL DBs for login/char/map servers this is the list of databases each server use:

1. login-server: global_reg_value, ipbanlist, login, loginlog
2. map-server: mapreg, item_db, item_db2, mob_db, mob_db2
3. char-server: everything else + global_reg_value once again

Note that global_reg_value tables are needed by both login-server and char-server (though it may be different tables)

Configure Hercules

Compile Source Code

cd trunk
./configure
make sql

• If you're using CentOS 32-bit please use:

./configure --disable-64bit

How to Recompile

In the future (after you update or edit any file in /src) to recompile, add make clean before make sql:

cd trunk
./configure
make clean
make sql

Start your HerculesServer

//change access mode of athena-start file so that you can execute it.
//Use (dos2unix athena-start) if yo uare getting ^M errors ie. newline errors 
chmod a+x athena-start

//To Start
./athena-start start
//To Stop
./athena-start stop
//To Restart
./athena-start restart
