nextcloud前身是大名鼎鼎的owncloud，两者均是开源的网络硬盘系统。nextcloud不仅可以搭建私有云存储和同步数据，也提供联系人、日程管理功能，web端还提供私密的语音视频通话功能。nextcloud致力于数据安全，云端的数据均可选择加密，并遵循安全行业最佳实践。客户端支持windows、macos、linux三大pc平台，以及安卓ios两大移动平台，完全足够家庭或中小型团队协作使用。
nextcloud程序由php语言编写，因此部署需要具备php运行环境以及web中间件。因其支持平台众多，官方文档略显繁琐，故本文给出树莓派上用nginx、mariadb、redis搭建nextcloud的详细步骤。
从官网下载部署程序；
更新系统和必备软件：sudo apt update && sudo apt upgrade && sudo apt install -y libreoffice ffmpeg；
安装nginx：sudo apt install -y nginx；
安装redis：sudo apt install -y redis;
安装mariadb：sudo apt install mariadb-server；
安装php及推荐模块：sudo apt install -y php7.3 php7.3-fpm php7.3-curl php7.3-gd php7.3-dom php7.3-iconv php7.3-openssl php-redis php-MySQL php7.3-zip php7.3-bz2 php7.3-intl php7.3-imagick；
解压部署程序：unzip nextcloud-xxxx.zip；
将nextcloud文件移动到网站根目录：sudo mv nextcloud-xxx /var/www/html/nextcloud；
创建数据目录，更改目录权限：mkdir /var/www/html/nextcloud/data && sudo chown -R www-data:www-data /var/www/html/nextcloud；
配置php：打开**/etc/php/7.3/fpm/php.ini**文件，做如下更改：
expose_php改成off
date.timezone 一行删掉前面的;号，值改成Asia/Shanghai
删掉opcache.enable=1，opcache.validate_timestamps=1，opcache.revalidate_freq=2这三行前面的;号，将opcache.revalidate_freq的值改成30;
配置fpm：打开**/etc/php/7.3/fpm/pool.d/www.conf**文件，移除clear_env=no，env[开头那几行前面的;号（即388，401-405这几行前面的分号）；
设置mariadb管理员密码： mysqladmin -uroot password '你的密码';
创建nextcloud数据库：mysql -uroot -p'你的密码' -e 'create user nextcloud@"%" identified by "nextcloud数据库密码"; create database nextcloud default charset=utf8mb4; grant all privileges on nextcloud.* to nextcloud@"%"; flush privileges;'；
配置nginx：在**/etc/nginx/sites-enabled**目录下，创建一个nextcloud文件，其内容如下（注意，本配置中禁用了https）：
upstream php-handler {
server unix:/run/php/php7.3-fpm.sock;
}
server {
listen 80;
listen [::]:80;
server_name cloud.example.com;
# enforce https
#return 301 https://$server_name:443$request_uri;
#}
#server {
# listen 443 ssl http2;
# listen [::]:443 ssl http2;
# server_name cloud.example.com;
# Use Mozilla's guidelines for SSL/TLS settings
# https://mozilla.github.io/server-side-tls/ssl-config-generator/
# NOTE: some settings below might be redundant
# ssl_certificate /etc/ssl/nginx/cloud.example.com.crt;
# ssl_certificate_key /etc/ssl/nginx/cloud.example.com.key;
# Path to the root of your installation
root /var/www/html/nextcloud;
location = /robots.txt {
allow all;

access_log off;
}

location = /.well-known/carddav {
return 301 $scheme://$host:$server_port/remote.php/dav;
}
location = /.well-known/caldav {
return 301 $scheme://$host:$server_port/remote.php/dav;

access_log off;
}
}启动各项服务：sudo systemctl restart nginx php7.3-fpm redis-server mariadb。如果系统安装了防火墙，记得放行80端口；
打开浏览器，在地址栏输入树莓派的ip，例如：http://192.168.1.2，将出现nextcloud的设置页面，选择用户名和密码，以及输入数据库用户名和密码，完成设置。
设置完成后，进入了类似百度云盘的操作界面，说明云盘已经初步搭建好了。
配置nextcloud，使其性能更好：打开**/var/www/html/nextcloud/config/config.php**文件，在最后的);前添加缓存配置： 'memcache.local' => '\OC\Memcache\Redis', 'memcache.distributed' => '\OC\Memcache\Redis', 'redis' => [ 'host' => 'localhost', 'port' => 6379, 'dbindex' => 0, 'password' => '', 'timeout' => 1.5, ],
至此，nextcloud的部署和设置全部完毕，在浏览器界面已经能够查看和管理各种数据和功能了。
树莓派默认的sd卡存储空间很小，实践应该将nextcloud的程序文件托管在外置硬盘上；
设置外网访问需要用到域名、DNS、https配置以及内网穿透，本文不再给出；
各平台客户端的设置和使用请参考官方教程，本文不再给出
