在树莓派上基于 LNMP 搭建 Nextcloud

最近更新于 2024-10-04 20:07

环境

  • 树莓派CM4
  • raspios 20240704 Debian 12 arm64

搭建 LNMP 环境

安装 Nginx

sudo apt update
sudo apt install -y nginx

安装 php 及功能组件支持

参考:https://docs.nextcloud.com/server/latest/admin_manual/installation/php_configuration.html

sudo apt install -y php php-common php-fpm php-curl php-xml php-fileinfo php-gd php-json php-mbstring php-posix php-simplexml php-xmlreader php-xmlwriter php-zip php-mysql php-intl php-ldap php-ftp php-imap php-bcmath php-gmp php-exif php-apcu php-memcached php-redis php-imagick php-tidy php-uuid php-gnupg ffmpeg

安装数据库

MySQL 官方没有提供适用 Debian 12 arm64 的二进制安装包
file

可以自己用 MySQL 社区版源码编译或者找三方编译的安装包,这里使用 MySQL 的开源替代软件 Mariadb,可以直接用官方软件源安装

sudo apt install -y mariadb-server

配置 Nginx 和 PHP 连接

参考:https://docs.nextcloud.com/server/latest/admin_manual/installation/nginx.html#nextcloud-in-the-webroot-of-nginx
以 root 权限编辑 /etc/nginx/sites-available/default,写入(只是模板,需要自己改)
这个配置比较适用配置在公网服务器

upstream php-handler {
    # server 127.0.0.1:9000;
    server unix:/run/php/php-fpm.sock;
}

# Set the `immutable` cache control options only for assets with a cache busting `v` argument
map $arg_v $asset_immutable {
    "" "";
    default ", immutable";
}

server {
    # http
    listen 80;
    listen [::]:80;
    server_name cloud.example.com; # 自己的域名,IP 访问改为一个下划线

    # Prevent nginx HTTP Server Detection
    server_tokens off;

    # Enforce HTTPS
    return 301 https://$server_name$request_uri;
}

server {
    # https
    # 如果不是部署到公网,就将上一个 server 删掉,把这里的监听 443 端口改为 80,并删掉 **ssl http2**
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    # With NGinx >= 1.25.1 you should use this instead:
    # listen 443      ssl;
    # listen [::]:443 ssl;
    # http2 on;
    server_name cloud.example.com; # 自己的域名,IP 访问改为一个下划线

    # Specify how to handle directories -- specifying `/index.php$request_uri`
    # here as the fallback means that Nginx always exhibits the desired behaviour
    # when a client requests a path that corresponds to a directory that exists
    # on the server. In particular, if that directory contains an index.php file,
    # that file is correctly served; if it doesn't, then the request is passed to
    # the front-end controller. This consistent behaviour means that we don't need
    # to specify custom rules for certain paths (e.g. images and other assets,
    # `/updater`, `/ocs-provider`), and thus
    # `try_files $uri $uri/ /index.php$request_uri`

安装 Nextcloud

Nextcloud 网站源码下载:https://nextcloud.com/install/
展开社区项目
file
下载 ZIP 包
file

解压得到的 nextcloud 放到 /var/www 路径下,并在这个路径下修改文件权限:https://blog.iyatt.com/?p=14780
后面创建数据库和配置安装和 WordPress 差不多:https://blog.iyatt.com/?p=12732#WordPress_%E5%AE%89%E8%A3%85
只是登录数据库 root 的方式从 mysql -u root -p 改为 sudo mysql

访问页面,首次配置一下数据库连接信息和登录账号
file

然后登录进入页面
file

改进配置

修改 PHP 限制

Nextcloud 建议 php 内存限制至少有 512M,根据自己实际情况调整,我这里树莓派有 8G 内存,直接把 PHP 限制改为 1G
以 root 权限编辑 /etc/php/8.2/fpm/php.ini,路径中的 8.2 是 php 版本,根据自己的实际情况修改
找到 memory_limt 把后面的值修改了
file

修改上传文件大小限制(upload_max_filesize),默认 2M,这里改为 512M
file

修改 post 大小限制(post_max_size),默认 8M,这里改为 512M
file

然后重启 php-fpm,其中 8.2 换成自己的 php 版本

sudo systemctl restart php8.2-fpm

file

后台任务使用 cron 执行

创建定时任务

sudo crontab -u www-data -e

自己选择一个编辑器,然后写入(/var/www/nextcloud 是网站文件路径)

*/5  *  *  *  * /usr/bin/php -f /var/www/nextcloud/cron.php

file

然后 Nextcloud 设置 -> 基本设置 -> 后台任务,选择 Cron
file

配置电子邮件服务器(发邮件)

先在设置的个人信息里填上邮箱(用于验证接收)
file

再到基本设置,我这里使用 QQ 邮箱的 STMP 服务来实现发邮件
QQ 邮箱:https://mail.qq.com
获取一个专用的密码
file

file

设置默认电话区域

以 root 权限编辑 Nexcloud 目录下的 config/config.php,追加

'default_phone_region' => 'CN',

file

开启 PHP OPcache

开这个就是把编译过的 PHP 脚本缓存到内存里(内存足够的话),这样可以提升性能。
以 root 权限编辑 /etc/php/8.2/fpm/php.ini,找到 [opcache] 添加下面内容(也可以解开注释编辑参数)

opcache.enable=1
opcache.enable_cli=1
opcache.memory_consumption=128
opcache.interned_strings_buffer=16
opcache.max_accelerated_files=10000
opcache.save_comments=1
opcache.revalidate_freq=1

file

重启 PHP-FPM 生效

解决 PHP 访问环境变量

以 root 编辑 /etc/php/8.2/fpm/pool.d/www.conf,找到 env[PATH]
file

去掉前面的分号
file

重启 PHP-FPM 生效

添加缺失的索引(Detected some missing optional indices. 问题)

命令行切换到 Nextcloud 路径下,执行

sudo -u www-data php occ db:add-missing-indices

file

设置维护时间段开始时间

比如将一些复杂操作的时间调整到不常用的时间段,避开使用高峰,默认是任意时间段
以 root 编辑 Nextcloud 目录下的 config/config.php,添加

'maintenance_window_start' => 1,

意味着会从凌晨 1 点开始(持续 4 小时)
file

解决 “您的网络服务器未正确设置来解析 .wellknown URL,失败于: /.well-known/webfinger 更多细节”

我这里出现这个问题是因为使用的端口是非标端口,访问链接后面要指定端口,但是这里的跳转没正确处理
file

以 root 编辑 /etc/nginx/sites-available/default,把上图选中的两行和后面return那行分别修改为

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

        return 301 $scheme://$http_host/index.php$request_uri;

然后重启 Nginx

修改默认存储路径

编辑 Nextcloud 目录下 config/config.php 中的 datadirectory
file

配置局域网代理

如果网络不好,无法访问应用商店
以 root 编辑 Nextcloud 目录下 config/config.php,添加

'proxy' => 'sock5://IP:端口'

'proxy' => 'http://IP:端口'

file

file

mimetype迁移

在管理员设置概览中提示“One or more mimetype migrations are available. Occasionally new mimetypes are added to better handle certain file types. Migrating the mimetypes take a long time on larger instances so this is not done automatically during upgrades. Use the command occ maintenance:repair --include-expensive to perform the migrations.”时
终端进入 Nextcloud 目录,执行

# 启用维护模式
sudo -u www-data php occ maintenance:mode --on

# 执行迁移
sudo -u www-data php occ maintenance:repair --include-expensive

# 管理维护模式
sudo -u www-data php occ maintenance:mode --off

配置内存缓存

安装 redis 等组件

sudo apt install -y redis php-redis php-apcu

以 root 编辑 /etc/redis/redis.conf
找到 unixsocket 和 uxixsocketperm 解开注释,并把权限值改为 770
file
找到 port,把端口号改为 0
file

保存退出后重启 redis

# 设置自启动
sudo systemctl enable redis-server

# 重启
sudo systemctl restart redis-server

将 www-data 用户添加到 redis 用户组

# 添加
sudo usermod -aG redis www-data

# 刷新
sudo newgrp redis

测试访问 redis 套接字,显示 PONG 即成功

sudo -u www-data redis-cli -s /var/run/redis/redis-server.sock ping

以 root 编辑 /etc/php/8.2/cli/php.ini 添加

[apcu]
apc.enable_cli=1

重启 Nginx 和 PHP-fpm

sudo systemctl restart php8.2-fpm.service nginx

在 Nextcloud 目录下的 config/config.php 添加

  'memcache.local' => '\OC\Memcache\APCu',
  'memcache.locking' => '\OC\Memcache\Redis',
  'redis' => array(
     'host' => '/var/run/redis/redis-server.sock',
     'port' => 0,
     'timeout' => 0.0,
      ),

file

上传时发生错误,状态码413

在网页端上传大文件的时候遇到,这个是超出了 Nginx 上传限制导致的。Nextcloud 文档给的 Nginx 模板默认配置是限制 512M,把 client_max_body_size 改大再重启 Nginx 就行,比如我这里直接改成 10240M 即 10G
file

插件及使用技巧

Two-Factor TOTP Provider【二次验证,一次性密码】

可以绑定 APP,通过 APP 查看一次性密码,在登陆时进行验证
file

file

Two-Factor Authentication via Nextcloud notification 【二次验证,已登陆设备验证】

可以发送通知,在已登陆设备的通知里同意登录
file

External storage support 【存储扩展】

可以向 Nextcloud 中添加存储路径,比如挂载了额外的硬盘,把路径添加进去,也能添加其它共享协议或平台
file

Memories 【相册管理】

安装这个插件后,基本功能可以按时间、文件夹、地理位置管理
file

file

反向地理编码下载地球数据库注意

数据库下载后导入时可能处理超时,如果出现超时失败,可以登录数据库,设置延长限制
file

SET GLOBAL wait_timeout = 28800;
SET GLOBAL interactive_timeout = 28800;

图片内容识别功能

可以再安装 Recognize 和 Face Recognition,在此之前最好保证环境配置好

安装 Node.js

# 安装 npm
sudo apt install -y npm

# 安装版本管理工具
sudo npm i -g n

# 更新 Node.js 到最新稳定版
sudo n stable

配置 Composer

# 安装工具
sudo apt install -y build-essential git

# 获取源码
git clone https://github.com/composer/getcomposer.org.git --depth=1 && cd getcomposer/web

# 构建
bash installer

# 拷贝到系统目录
mv composer.phar /usr/local/bin/composer

安装 PDLIB(人脸识别需要)

# 安装构建工具
sudo apt install -y cmake php-dev

# 获取 DLIB 源码
cd /tmp && git clone https://github.com/davisking/dlib.git --depth=1 && cd dlib/dlib

# 创建编译目录
mkdir build && cd build

# 生成编译脚本
cmake -DBUILD_SHARED_LIBS=ON ..

# 编译
make -j$(nproc)

# 安装
sudo make install

# 获取 PDLIB 源码
cd /tmp && git clone https://github.com/goodspb/pdlib.git && cd pdlib

# 生成编译 PHP 扩展的配置文件
phpize

# 配置编译
./configure --enable-debug
# you may need to indicate the dlib install location
# PKG_CONFIG_PATH=/usr/local/lib/pkgconfig ./configure --enable-debug

# 编译
make -j$(nproc)

# 安装
sudo make install

编辑 PHP 配置文件 /etc/php/8.2/fpm/php.ini,写入

[pdlib]
extension="pdlib.so"

file

重启 PHP 服务

sudo systemctl restart php8.2-fpm

安装前面提到的两个插件并启用后,管理设置中,配置好 node 路径 /usr/local/bin/node
file

终端进入 Nextcloud 根目录,安装预览生成器

sudo -u www-data php occ app:install previewgenerator

file

可选的人脸识别模型:https://github.com/matiasdelellis/facerecognition/wiki/Models#install-models
在 Nextcloud 目录下执行下载模型

# 设置可用内存大小,比如 2G
sudo -u www-data php occ face:setup -M 2G

# 设置模型,比如选 1
sudo -u www-data php occ face:setup -m 1

Nextcloud Office 【在线文档支持】

需要独立搭建 Collabora Online 服务器,或者使用内建版(功能没那么丰富),内建版可以切换终端路径到 Nextcloud 下,然后安装

sudo -u www-data ./occ app:install richdocumentscode_arm64

设置选内建版,会提示安装用什么命令(不同架构可能不同)
file

然后在 Nginx 关于 Nextcloud 的配置中加上
(参考:https://www.collaboraonline.com/blog/connecting-collabora-online-built-in-code-server-with-nginx/

    # Collabora Online 支持
    location ~ \.php(?:$|/) {
        # Required for legacy support
        rewrite ^/(?!index|remote|public|cron|core\/ajax\/update|status|oc[ms]\/v[12]|updater\/.+|oc[ms]-provider\/.+|.+\/richdocumentscode_arm64\/proxy) /index.php$request_uri;

        fastcgi_split_path_info ^(.+?\.php)(/.*)$;
        set $path_info $fastcgi_path_info;

        try_files $fastcgi_script_name =404;

        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param PATH_INFO $path_info;
        fastcgi_param HTTPS on;

        fastcgi_param modHeadersAvailable true; # Avoid sending the security headers twice
        fastcgi_param front_controller_active true; # Enable pretty urls
        fastcgi_pass php-handler;

        fastcgi_intercept_errors on;
        fastcgi_request_buffering off;

        fastcgi_max_temp_file_size 0;
    }

重启 Nginx 服务器,之后在 Nextcloud 中就能使用在线文档了
设置勾选 office open xml,默认就会使用微软的 office 格式
file

file

Music 音乐

支持组织网盘上的音频文件
file

支持互联网电台,可以添加广播电台的流媒体链接听广播
file

世界广播地图:https://worldradiomap.com/zhongwen
可以在这个网站听广播,也能获取流媒体链接添加到 Nextcloud

手机端音乐方案

NextCloud 手机客户端里用不了这个插件,只是本身单曲选中播放倒是可以,浏览器打开网页倒是可以使用,但是没法后台保持播放。因为手机的电源策略,打开的网页切换到后台或者熄屏不久就会关闭播放,但是又不想要把浏览器设置成电源不限,这样浏览器就会一直在后台运行。
file

好在这个插件提供了 Ampache 和 Subsonic 方案,可以使用第三方的 APP 连接使用,上面有超链接指引推荐的 APP
file

我是 Android 手机,使用的 Power Ampache 2,在 Google Play 上安装是收费的,不过 GitHub 也提供了安装包,可以自己下载安装。
file


我最开始考虑的其它方案,可以不使用 Music 插件。使用支持 NextCloud 或者 WebDav 的云音乐播放器,如果担心网盘文件泄露,可以单独添加一个账号,然后将音乐文件目录共享给新建的用户,这样音乐软件就访问不了其它文件。只是没找到免费且好用的软件,要不是免费功能不够,要不是就是要收费。
