喺 Ubuntu 18.04 安裝 NextCloud 13

#下載／安裝
sudo apt install apache2
#disable directory listing，你可以 manual 改隻 conf 檔案都得
sudo sed -i "s/Options Indexes FollowSymLinks/Options FollowSymLinks/" /etc/apache2/apache2.conf
#啟動隻 apache2
sudo systemctl stop apache2.service
sudo systemctl start apache2.service
sudo systemctl enable apache2.service

#下載／安裝
sudo apt install mariadb-server mariadb-client
#啟動隻 MariaDB
sudo systemctl stop mariadb.service
sudo systemctl start mariadb.service
sudo systemctl enable mariadb.service
#secure 隻 MariaDB server
sudo mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none): XXXXXXXXXX
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

You already have a root password set, so you can safely answer 'n'.

Change the root password? [Y/n] n
 ... skipping.

By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] Y
 ... Success!
 
Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.
尸
Disallow root login remotely? [Y/n] n
 ... skipping.

By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] Y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!
 
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] Y
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

#登入之後，首先 create 隻 database
CREATE DATABASE nextcloud;
#Create 另一個 user，專門俾 NextCloud 用

#准哩個 user remote 登入，我諗住可以有備無患啫
GRANT USAGE ON *.* TO 'nxstudio'@'%' IDENTIFIED BY 'XXXXXXXXXX';
#准埋 root user remote 登入
GRANT USAGE ON *.* TO 'root'@'%' IDENTIFIED BY 'XXXXXXXXXX';
#准 user nxstudio 用 database 'nextcloud'
GRANT ALL ON nextcloud.* TO 'nxstudio'@'%' IDENTIFIED BY 'XXXXXXXXXX' WITH GRANT OPTION;

到此，你隻 NextCloud 已經可以用得！🤓 以下係 NextCloud Tuning。

#修改 PHP 隻 ini 檔案
#PHP 用 memory caches，前題係你有安裝 PHP-FPM 又叫（FastCGI），我哋有 :)
sudo vi /etc/php/7.2/fpm/conf.d/10-opcache.ini
#加下面幾行
opcache.enable=1
opcache.enable_cli=1
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=10000
opcache.memory_consumption=128
opcache.save_comments=1
opcache.revalidate_freq=1

#下載/安裝 Redis
sudo apt install redis-server php-redis -y
#修改 /var/www/nextcloud/config/config.php 如果你打算淨係用 Redis 做哂 cache + locking
'memcache.local' => '\\OC\\Memcache\\Redis',
'memcache.locking' => '\\OC\\Memcache\\Redis',
'redis' => array(
'host' => 'localhost',
'port' => 6379,
),

#下載/安裝 PHP APCu
sudo apt install php-apcu -y
#修改 /var/www/nextcloud/config/config.php 如果你打算用 Redis 做 locaking 同時用 PHP ACPu 做 cache
'memcache.local' => '\OC\Memcache\APCu',
'memcache.locking' => '\\OC\\Memcache\\Redis',
'redis' => array(
'host' => 'localhost',
'port' => 6379,
),
