nextcloud 係由 owncloud 滋生出嚟，事源有份參與開發 owncloud 的工程師不滿 owncloud 嘅原碼開放政策，一同離隊，另外成立公司再搞過，由於開源所以很快就聚集咗一群有心有力人士，搞得有聲有色，特別係 WebDAV API 方面做得比較好，仲有 C# 嘅 library 可以用，可以上 Xamarin 添，於是，我又學人跳槽。😀
首先，準備一隻 Ubuntu LAMP ＋SSH，我用 Ubuntu 16.0.4 :
用 apt-get update && apt-get upgrade 一下，然後安裝 php modules：
sudo apt-get install php-gd php-json php-mysql php-curl php-intl php-mcrypt php-imagick php-zip php-dom php-xml php-mbstring
去官網下載最新嘅 nextcloud：
wget https://download.nextcloud.com/server/releases/latest-12.tar.bz2
解壓，同時放喺 apache 之內：
sudo tar -C /var/www -xvjf latest-12.tar.bz2
同 own cloud 一樣，你要手動改一下啲 files 嘅 access rights，同時要加番啲未有嘅檔案夾。因為比較多句子，可以做一個 bash script，唔使打得咁麻煩：
sudo vi permission.sh
抄哩段 script：
#!/bin/bash
ocpath='/var/www/nextcloud'
htuser='www-data'
htgroup='www-data'
rootuser='root'
printf “Creating possible missing Directories\n”
mkdir -p $ocpath/data
mkdir -p $ocpath/updater
printf “chmod Files and Directories\n”
find ${ocpath}/ -type f -print0 | xargs -0 chmod 0640
find ${ocpath}/ -type d -print0 | xargs -0 chmod 0750
printf “chown Directories\n”
chown -R ${rootuser}:${htgroup} ${ocpath}/
chown -R ${htuser}:${htgroup} ${ocpath}/apps/
chown -R ${htuser}:${htgroup} ${ocpath}/config/
chown -R ${htuser}:${htgroup} ${ocpath}/data/
chown -R ${htuser}:${htgroup} ${ocpath}/themes/
chown -R ${htuser}:${htgroup} ${ocpath}/updater/
chmod +x ${ocpath}/occ
printf “chmod/chown .htaccess\n”
if [ -f ${ocpath}/.htaccess ]
then
chmod 0644 ${ocpath}/.htaccess
chown ${rootuser}:${htgroup} ${ocpath}/.htaccess
fi
if [ -f ${ocpath}/data/.htaccess ]
then
chmod 0644 ${ocpath}/data/.htaccess
chown ${rootuser}:${htgroup} ${ocpath}/data/.htaccess
fi
執行：
sudo bash permisssion.sh
Output 大概跟這個相同：
Creating possible missing Directories chmod Files and Directories chown Directories chmod/chown .htaccess
加個 website 嘅 config file，或者：
<VirtualHost *:80>
DocumentRoot “/var/www/nextcloud”
ServerName yours.domain.com
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
<Directory /var/www/nextcloud/>
Options +FollowSymlinks
AllowOverride All
<IfModule mod_dav.c>
Dav off
</IfModule>
SetEnv HOME /var/www/nextcloud
SetEnv HTTP_HOME /var/www/nextcloud
Satisfy Any
</Directory>
</VirtualHost>
我想用 root，於是就照用 default website，不過改咗少少：
<VirtualHost *:80>
# The ServerName directive sets the request scheme, hostname and port that
# the server uses to identify itself. This is used when creating
# redirection URLs. In the context of virtual hosts, the ServerName
# specifies what hostname must appear in the request's Host: header to
# match this virtual host. For the default virtual host (this file) this
# value is not decisive as it is used as a last resort host regardless.
# However, you must set it for any further virtual host explicitly.
#ServerName www.example.com
ServerAdmin webmaster@localhost
DocumentRoot /var/www/nextcloud
ServerName yours.doamin.com
# Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
# error, crit, alert, emerg.
# It is also possible to configure the loglevel for particular
# modules, e.g.
#LogLevel info ssl:warn
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
# For most configuration files from conf-available/, which are
# enabled or disabled at a global level, it is possible to
# include a line for only one particular virtual host. For example the
# following line enables the CGI configuration for this host only
# after it has been globally disabled with "a2disconf".
#Include conf-available/serve-cgi-bin.conf
</VirtualHost>
# vim: syntax=apache ts=4 sw=4 sts=4 sr noet
要 enable module rewrite：
sudo a2enmod rewrite
可以 reload 隻 apache，或者 restart：
sudo systemctl reload apache2 or sudo service apache2 restart
最後就係去訪問你隻 nextcloud：
照答問題，完成最後步驟，create 第一個 user (admin user)，同時 create 你個 nextcloud database！哩度係要答你安裝 LAMP 嘅時候你俾 MySQL 嘅 user name 同密碼：
唔好話俾我知你當時冇抄低。😜
*** 完 ***
P.S. mass copy 之後 rescan 啲檔案：
個 command 要喺你安裝咗 nextcloud 嘅 root 執行先有效，即係要先 cd 一下。
