nextcloud簡介

nextcloud前身是大名鼎鼎的owncloud，二者均是開源的網絡硬盤系統。nextcloud不只能夠搭建私有云存儲和同步數據，也提供聯繫人、日程管理功能，web端還提供私密的語音視頻通話功能。nextcloud致力於數據安全，雲端的數據都可選擇加密，並遵循安全行業最佳實踐。客戶端支持windows、macos、linux三大pc平臺，以及安卓ios兩大移動平臺，徹底足夠家庭或中小型團隊協做使用。

部署和設置nextcloud

nextcloud程序由php語言編寫，所以部署須要具有php運行環境以及web中間件。因其支持平臺衆多，官方文檔略顯繁瑣，故本文給出樹莓派上用nginx、mariadb、redis搭建nextcloud的詳細步驟。

1. 從官網下載部署程序；
2. 更新系統和必備軟件：sudo apt update && sudo apt upgrade && sudo apt install -y libreoffice ffmpeg；
3. 安裝nginx：sudo apt install -y nginx；
4. 安裝redis：sudo apt install -y redis;
5. 安裝mariadb：sudo apt install mariadb-server；
6. 安裝php及推薦模塊：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；
7. 解壓部署程序：unzip nextcloud-xxxx.zip；
8. 將nextcloud文件移動到網站根目錄：sudo mv nextcloud-xxx /var/www/html/nextcloud；
9. 建立數據目錄，更改目錄權限：mkdir /var/www/html/nextcloud/data && sudo chown -R www-data:www-data /var/www/html/nextcloud；

10. 配置php：打開/etc/php/7.3/fpm/php.ini文件，作以下更改：

    1. expose_php改爲off
    2. date.timezone 一行刪掉前面的;號，值改爲Asia/Shanghai
    3. 刪掉opcache.enable=1，opcache.validate_timestamps=1，opcache.revalidate_freq=2這三行前面的;號，將opcache.revalidate_freq的值改爲30;
11. 配置fpm：打開/etc/php/7.3/fpm/pool.d/www.conf文件，移除clear_env=no，env[開頭那幾行前面的;號（即388，401-405這幾行前面的分號）；
12. 設置mariadb管理員密碼： mysqladmin -uroot password '你的密碼';
13. 建立nextcloud數據庫：mysql -uroot -p'你的密碼' -e 'create user nextcloud@"%" identified by "nextcloud數據庫密碼"; create database nextcloud default charset=utf8mb4; grant all privileges on nextcloud.* to nextcloud@"%"; flush privileges;'；

14. 配置nginx：在/etc/nginx/sites-enabled目錄下，建立一個nextcloud文件，其內容以下（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;
        log_not_found off;
        access_log off;
    }
    
    # The following 2 rules are only needed for the user_webfinger app.
    # Uncomment it if you're planning to use this app.
    #rewrite ^/.well-known/host-meta /public.php?service=host-meta last;
    #rewrite ^/.well-known/host-meta.json /public.php?service=host-meta-json last;
    
    # The following rule is only needed for the Social app.
    # Uncomment it if you're planning to use this app.
    #rewrite ^/.well-known/webfinger /public.php?service=webfinger last;
    
    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;
    }

        try_files $uri/ =404;
        index index.php;
    }

    }
    
    location ~ \.(?:png|html|ttf|ico|jpg|jpeg|bcmap)$ {
        try_files $uri /index.php$request_uri;
        # Optional: Don't log access to other assets
        access_log off;
    }
    }

15. 啓動各項服務：sudo systemctl restart nginx php7.3-fpm redis-server mariadb。若是系統安裝了防火牆，記得放行80端口；
16. 打開瀏覽器，在地址欄輸入樹莓派的ip，例如：http://192.168.1.2，將出現nextcloud的設置頁面，選擇用戶名和密碼，以及輸入數據庫用戶名和密碼，完成設置。
17. 設置完成後，進入了相似百度雲盤的操做界面，說明雲盤已經初步搭建好了。
18. 配置nextcloud，使其性能更好：打開/var/www/html/nextcloud/config/config.php文件，在最後的);前添加緩存配置： `'memcache.local' => 'OCMemcacheRedis',

'memcache.distributed' => 'OCMemcacheRedis',
'redis' => [

'host'     => 'localhost',
 'port'     => 6379,
 'dbindex'  => 0,
 'password' => '',
 'timeout'  => 1.5,

],`

至此，nextcloud的部署和設置所有完畢，在瀏覽器界面已經可以查看和管理各類數據和功能了。

其它

1. 樹莓派默認的sd卡存儲空間很小，實踐應該將nextcloud的程序文件託管在外置硬盤上；
2. 設置外網訪問須要用到域名、dns、https配置以及內網穿透，本文再也不給出；
3. 各平臺客戶端的設置和使用請參考官方教程，本文再也不給出
