Usenet Indexer Installation - Redhat / CentOS 7

System Vorbereitungen

1. Hinzufügen von benötigten Repos und aktualisieren des Systems:

   # 
   # yum-config-manager --add-repo=http://negativo17.org/repos/epel-multimedia.repo
   
   # yum update -y

2. Installation der benötigten Grundpakete:

   # yum groupinstall "Development Tools" "Development Libraries"
   # yum install yasm git p7zip tmux time composer mediainfo wget vim curl ffmpeg boost-regex boost-devel swig gcc-c++ httpd php56u-cli php56u-mcrypt php56u-mysqlnd php56u-gd php56u-xml php56u-pear php56u-mbstring php56u-pecl-jsonc-devel php56u-process php56u-pecl-jsonc php56u-pecl-imagick php56u php56u-common php56u-pdo php56u-devel mariadb100u mariadb100u-common mariadb100u-libs mariadb100u-server mariadb100u-config mariadb100u-errmsg perl-Text-Template libevent-devel ncurses-devel 
   y

3. Weitere System Vorbereitungen:

   # useradd -c nzedb nzedb
   # usermod -a -G nzedb apache

Konfiguration des Webservers

Im ersten Schritt, erstellen wir unter: /etc/apache2/sites-available/ einen neuen Virtual-Host, für unseren späteren Usenet Indexer:

# vim /etc/apache2/sites-available/nzedb.conf

<VirtualHost *:80>
    ServerName 127.0.0.1
    ServerAdmin webmaster@localhost
    ServerSignature Off

    DocumentRoot "/var/www/nZEDb/www"

    LogLevel warn
    ErrorLog /var/log/apache2/error.log
    
    Alias /nZEDb /var/www/nZEDb/www
    Alias /covers /var/www/nZEDb/resources/covers
    
    <Directory "/var/www/nZEDb/www">
        Options FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>

    ProxyPassMatch ^/(.*\.php(/.*)?)$ unix:/run/php/php7.0-fpm.sock|fcgi://localhost/var/www/nZEDb/www
</VirtualHost>

# sed -i "s/ServerTokens OS/ServerTokens Prod/" /etc/apache2/conf-available/security.conf
# sed -i "s/ServerSignature On/ServerSignature Off/" /etc/apache2/conf-available/security.conf

Nun wird als erstes der Default-Virtual-Host deaktiviert, unser neuer aktiviert und das Rewrite-Modul enabled:

# mkdir -p /var/www/nZEDb/www

# a2dissite 000-default
# a2ensite nzedb.conf

# a2enmod rewrite

# systemctl enable apache2

Konfiguration von PHP 7.0

We already installed all needed PHP extensions earlier. For best performance, we also need to configure some PHP settings. :

# php --ini |grep Loaded

Loaded Configuration File:         /etc/php/7.0/cli/php.ini

In our case, we have to make changes first to the /etc/php/7.0/cli/php.ini file. We will increase the default upload limit to 2000 MB. You can set the values according to your needs. Run the following commands:

# sed -i "s/max_execution_time = 30/max_execution_time = 120/" /etc/php/7.0/cli/php.ini
# sed -i "s/;date.timezone =/date.timezone = Europe\/Zurich/" /etc/php/7.0/cli/php.ini

Now we have to do the same for our php7.0-fpm Configuration:

# sed -i "s/max_execution_time = 30/max_execution_time = 120/" /etc/php/7.0/fpm/php.ini
# sed -i "s/memory_limit = 128M/memory_limit = 1024M/" /etc/php/7.0/fpm/php.ini
# sed -i "s/;date.timezone =/date.timezone = Europe\/Zurich/" /etc/php/7.0/fpm/php.ini

# echo "<?php phpinfo(); ?>" > /var/www/nZEDb/www/phpinfo.php
# systemctl start php7.0-fpm
# systemctl enable php7.0-fpm

# a2enmod proxy_fcgi
# systemctl restart apache2

Check PHP-Configuration at: IP-From-SERVER/phpinfo.php

Konfiguration Mariadb

Erstellen einer neuen MariaDB spezifischen Konfiguration:

# vim /etc/mysql/mariadb.conf.d/50-server.cnf

# configurations by nZEDb
innodb_file_per_table = 1
max_allowed_packet = 16M
group_concat_max_len = 8192

Nach dem Speichern, wird im nächsten Schritt die MariaDB enabled und gestartet!

# systemctl start mysql.service
# systemctl enable mysql.service

# /usr/bin/mysql_secure_installation

Enter current password for root (enter for none): Enter
Set root password? [Y/n]: Y
New password: <your-password>
Re-enter new password: <your-password>
Remove anonymous users? [Y/n]: Y
Disallow root login remotely? [Y/n]: Y
Remove test database and access to it? [Y/n]: Y
Reload privilege tables now? [Y/n]: Y

Erstellen der Datenbank & Konfiguration von AppArmor

Erstellen der von nZEDb benötigten Datenbank und Users:

mysql -u root -p

MariaDB [(none)]> CREATE DATABASE nzedb;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nzedb.* TO 'nzedbuser'@'localhost' IDENTIFIED BY 'YOUR-PASSWORD';
MariaDB [(none)]> GRANT FILE ON *.* TO 'nzedbuser'@'localhost';
MariaDB [(none)]> FLUSH PRIVILEGES;
MariaDB [(none)]> quit

# rm -Rf /var/www/nZEDb/
# cd /var/www/
# git clone https://github.com/nZEDb/nZEDb.git

# chown -R www-data:www-data /var/www/nZEDb
# chmod -R g+w /var/www/nZEDb/

# cp /var/www/nZEDb/_install/install.sh /var/www/
# chmod a+x /var/www/install.sh

# ./install.sh

Abschliessende Schritte zur Inbetriebnahme des Indexers

Web-GUI Konfiguration des frisch installierten Indexers

Systemd Unit-File erstellen zur Steuerung der Background Services

# cat >/etc/systemd/system/nzedb.service <<EOD

After=syslog.target

[Service]
WorkingDirectory=/var/www/nZEDb/misc/update/nix/tmux

[Install]
WantedBy=multi-user.target
EOD

# systemctl enable nzedb
# systemctl start nzedb
