OS

Following instruction is based on the CentOS7 installation as Minimal package.

After installing the OS, please change the SELinux setting to be Permissive or Disable.
Configuration file is located at /etc/sysconfig/selinux

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=permissive
# SELINUXTYPE= can take one of three two values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected.
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

The above setting allow you to boot the system as Permissive mode.
 Please also change the current mode to be Permissive.

setenforce Permissive

Next is the firewall setting. Install the firewalld and allow http and httpd.

sudo yum -y install firewalld
systemctl enable firewalld
systemctl start firewalld
sudo firewall-cmd --permanent --add-service=https
sudo firewall-cmd --permanent --add-service=http
sudo firewall-cmd --reload

Middleware Setup and Configuration

Database

Setup root password
/usr/bin/mysqladmin -u root password 'root-no-password'
Delete anonymous user from the initial database.
mysql -u root -proot-no-password
use mysql
delete from user where user='';
Create database for WEKO(NetCommon) installation
create database nc2db default character set UTF8;
Create an database user and assign the privilege to the previously created db.
grant all on nc2db.* to nc2user@localhost identified by 'nc2pass';

PHP

Open /etc/php.ini by editor.
Modify memory related configuration. Each size have to have the relationship as follows.
upload_max_filesize < post_max_size < memory_limit
For example,

memory_limit = 128M;
post_max_size = 64M;
upload_max_filesize = 32M;

Configure for UTF-8 character code .

[mbstring]
mbstring.language = neutral
mbstring.internal_encoding = UTF-8
mbstring.http_input = auto
mbstring.http_output = pass
mbstring.encoding_translation = Off

You also need to specify the timezone in the /etc/php.ini

[Date]
; Defines the default timezone used by the date functions
; http://www.php.net/manual/en/datetime.configuration.php#ini.date.timezone
date.timezone = "Asia/Tokyo"

After modifying the configuration, httpd have to be restarted.

sudo systemctl restart httpd

NetCommons2

Before Install Preparation

Install wget first.

sudo yum install -y wget

Download the latest NetCommons core package (Following command download version 2.4.2.1).

wget -c "http://www.netcommons.org/%E3%83%80%E3%82%A6%E3%83%B3%E3%83%AD%E3%83%BC%E3%83%89/%E3%82%B3%E3%82%A2%E3%83%91%E3%83%83%E3%82%B1%E3%83%BC%E3%82%B8/?action=cabinet_action_main_download&block_id=93&room_id=1&cabinet_id=1&file_id=2811&upload_id=6210" -O netcommons-2.4.2.1.tar.gz

Uncompress the downloaded file.

tar zxvf netcommons-2.4.2.1.tar.gz

Copy it to the web application directory.

sudo cp -rp NetCommons-2.4.2.1/html /var/www/html/nc2

Change file owner to be able to access by web server

cd /var/www/html/nc2
sudo chown -R apache:apache *

If you would like to access to NetCommons as a top page, you should modify /etc/httpd/conf/httpd.conf as follows.

DocumentRoot "/var/www/html/nc2/htdocs"

This is not a requirement, however, if you add the following expression in the httpd.conf, you can utilize the URL-rewrite option in OAI-PMH Configuration.

Please refer to User Manual (3.2.9.3.3 OAI-PMH Configuration) to know how to utilize this .htaccess configuration.

    <Directory "/var/www/html/nc2/htdocs">
        AllowOverride All
    </Directory>

Then restart the httpd

WEKO

Checkout WEKO module

In order to download the latest WEKO module from the source code repository, install the svn first

sudo yum install -y subversion

Checkout multilingual WEKO from the SVN site, then copy it to the NC2 module directory.
The current instruction is to utilize the trunk source code but we will prepare the stable one soon.

svn co http://forge.at.nii.ac.jp/svn/nc/repository/trunk repository
sudo cp -rp repository /var/www/html/nc2/webapp/modules/

Customization for Multilingual

Only English, Chinese and Japanese are available by the original NC2. Therefore, we need to apply patch for more multilingual function. First you need to checkout the patch and just copy it to the NC2 application directory.

svn co http://forge.at.nii.ac.jp/svn/nc/nc2multilang/trunk nc2multilang
cd nc2multilang
sudo cp -rp webapp /var/www/html/nc2/

MySQL DB also have to be modify for this customization.
In this SQL file database prefix for NC2 is assumed as "nc2" as has been instructed previously.
If you apply different prefix, please modify SQL file appropriately.
