NextCloud(https://nextcloud.com/)是開源的、可以用來搭建自己的文件同步和共享的私有云服務器，它是ownCloud的一個分支。

我使用LEMP做為NextCloud的運行環境－MariaDB, PHP-FPM 和 Nginx(Ubuntu 16.04)。

1、安裝MariaDB

Ubuntu 16.04 安裝 MariaDB

首先，更新升級系統：

$ sudo apt update

$ sudo apt upgrade

安裝MariaDB：

$ sudo apt install mariadb-server

啟動MariaDB服務：

$ sudo systemctl start mysql

查看狀態：

$ sudo systemctl status mysql

為例提高MariaDB的安全，我們可以執行初始化安全腳本：

$ sudo mysql_secure_installation

默認root密碼為空；然后設置root密碼和其他選項：

- Set root password? [Y/n] y

- Remove anonymous users? [Y/n] y

- Disallow root login remotely? [Y/n] y

- Remove test database and access to it? [Y/n] y

- Reload privilege tables now? [Y/n] y

登陸MariaDB命令行：

$ sudo mysql -u root -p

2、為NextCloud創建一個數據庫和用戶

$ sudo mysql -u root -p

MariaDB [(none)]> CREATE DATABASE nextcloud;

MariaDB [(none)]> GRANT ALL PRIVILEGES ON nextcloud.* TO 'nextcloud'@'localhost' IDENTIFIED BY 'test1234';

MariaDB [(none)]> FLUSH PRIVILEGES;

MariaDB [(none)]> \q

創建數據庫nextcloud；用戶名nextcloud，密碼test1234。

3、安裝PHP和相關模塊

$ sudo apt-get -y install php-fpm php-cli php-json php-curl php-imap php-gd php-mysql php-xml php-zip php-intl php-mcrypt php-imagick php-mbstring

配置PHP：

$ sudo sed -i "s/memory_limit = .*/memory_limit = 512M/" /etc/php/7.0/fpm/php.ini

$ sudo sed -i "s/;date.timezone.*/date.timezone = UTC/" /etc/php/7.0/fpm/php.ini

$ sudo sed -i "s/;cgi.fix_pathinfo=1/cgi.fix_pathinfo=1/" /etc/php/7.0/fpm/php.ini

$ sudo sed -i "s/upload_max_filesize = .*/upload_max_filesize = 200M/" /etc/php/7.0/fpm/php.ini

$ sudo sed -i "s/post_max_size = .*/post_max_size = 200M/" /etc/php/7.0/fpm/php.ini

重啟PHP-FPM：

$ sudo systemctl restart php7.0-fpm

4、下載NextCloud

下載地址：https://download.nextcloud.com/server/releases/，我安裝時最新版本是9.0.52。

$ cd /tmp

$ wget https://download.nextcloud.com/server/releases/nextcloud-9.0.52.zip

解壓到/var/www/目錄并更改權限：

$ unzip nextcloud-9.0.52.zip

$ sudo mkdir /var/www/

$ sudo mv nextcloud /var/www/

$ sudo chown -R www-data: /var/www/nextcloud

5、安裝配置Nginx

$ sudo apt-get install nginx nginx-extras

生成自簽名證書：

$ sudo mkdir -p /etc/nginx/ssl

$ cd /etc/nginx/ssl

$ sudo openssl genrsa -des3 -passout pass:x -out nextcloud.pass.key 2048

$ sudo openssl rsa -passin pass:x -in nextcloud.pass.key -out nextcloud.key

$ sudo rm nextcloud.pass.key

$ sudo openssl req -new -key nextcloud.key -out nextcloud.csr

$ sudo openssl x509 -req -days 365 -in nextcloud.csr -signkey nextcloud.key -out nextcloud.crt

也可以使用免費的let encrypt。

創建Nginx server block文件：

$ sudo vim /etc/nginx/sites-available/nextcloud

server {

listen 80;

server_name nextcloud.topspeedsnail.com;

return 301 https://$server_name$request_uri;

}

server {

listen 443 ssl http2;

server_name nextcloud.topspeedsnail.com;

root /var/www/nextcloud;

ssl on;

ssl_certificate /etc/nginx/ssl/nextcloud.crt;

ssl_certificate_key /etc/nginx/ssl/nextcloud.key;

ssl_session_timeout 5m;

ssl_ciphers ? 'AES128+EECDH:AES128+EDH:!aNULL';

ssl_protocols ?TLSv1 TLSv1.1 TLSv1.2;

ssl_prefer_server_ciphers on;

add_header X-Content-Type-Options nosniff;

add_header X-Frame-Options "SAMEORIGIN";

add_header X-XSS-Protection "1; mode=block";

add_header X-Robots-Tag none;

add_header X-Download-Options noopen;

add_header X-Permitted-Cross-Domain-Policies none;

access_log ?/var/log/nginx/nextcloud.access.log;

error_log ? /var/log/nginx/nextcloud.error.log;

location = /robots.txt {

allow all;

log_not_found off;

access_log off;

}

location = /.well-known/carddav {

return 301 $scheme://$host/remote.php/dav;

}

location = /.well-known/caldav {

return 301 $scheme://$host/remote.php/dav;

}

client_max_body_size 512M;

fastcgi_buffers 64 4K;

gzip off;

error_page 403 /core/templates/403.php;

error_page 404 /core/templates/404.php;

location / {

rewrite ^ /index.php$uri;

}

location ~ ^/(?:build|tests|config|lib|3rdparty|templates|data)/ {

deny all;

}

location ~ ^/(?:\.|autotest|occ|issue|indie|db_|console) {

deny all;

}

location ~^/(?:index|remote|public|cron|core/ajax/update|status|ocs/v[12]|updater/.+|ocs-provider/.+|core/templates/40[34])\.php(?:$|/) {

include fastcgi_params;

fastcgi_split_path_info ^(.+\.php)(/.+)$;

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

fastcgi_param PATH_INFO $fastcgi_path_info;

fastcgi_param HTTPS on;

#Avoid sending the security headers twice

fastcgi_param modHeadersAvailable true;

fastcgi_param front_controller_active true;

fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;

fastcgi_intercept_errors on;

fastcgi_request_buffering off;

}

location ~ ^/(?:updater|ocs-provider)(?:$|/) {

try_files $uri/ =404;

index index.php;

}

location ~* \.(?:css|js)$ {

try_files $uri /index.php$uri$is_args$args;

add_header Cache-Control "public, max-age=7200";

add_header X-Content-Type-Options nosniff;

add_header X-Frame-Options "SAMEORIGIN";

add_header X-XSS-Protection "1; mode=block";

add_header X-Robots-Tag none;

add_header X-Download-Options noopen;

add_header X-Permitted-Cross-Domain-Policies none;

# Optional: Don't log access to assets

access_log off;

}

location ~* \.(?:svg|gif|png|html|ttf|woff|ico|jpg|jpeg)$ {

try_files $uri /index.php$uri$is_args$args;

access_log off;

}

location ~ /\.ht {

deny all;

}

}

注意替換上面的域名。

創建鏈接：

$ sudo ln -s /etc/nginx/sites-available/nextcloud /etc/nginx/sites-enabled/nextcloud

測試Nginx配置文件：

$ sudo nginx -t

重啟nginx：

$ sudo systemctl restart nginx

6、完成安裝

使用瀏覽器訪問 https://your_domain_or_IP；

設置管理員賬戶和數據庫：
