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 Installation

sudo yum -y install epel-release sudo rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-5.el7.nux.noarch.rpm
Library for making PDF cover page.(PDFTK is unavailable for CentOS7, please skip this section. WEKO is looking for alternative method)
Library for showing multimedia contents.
sudo yum install -y ffmpeg
Middleware Setup and Configuration
Database
Setup root password
sudo systemctl restart mariadb /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
sudo systemctl restart 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/
