【LEDE】树莓派上玩LEDE终极指南-94-在树莓派上搭建NextCloud私人云存储注意事项

注意：在LEDE上安装完毕之后访问web显示No inputfile specified。
解决：
// php.ini
cgi.force_redirect = 0
cgi.fix_pathinfo=1
doc_root=

另一个问题：竟然有的Linux发行版不带stat命令！这里我就不报名字了。通过php日志可以发现:command stat : stat not found !
遂安装stat即可解决。希望在编译php的时候添加以上依赖。我就是掉进了这个坑！
opkg install coreutils-stat

Reference
Nextcloud is a free (Open Source) Dropbox-like software, a fork of the ownCloud project. Nextcloud is written in PHP and JavaScript, it supports many database systems such as, MySQL/MariaDB, PostgreSQL, Oracle Database and SQLite. In order to keep your files synchronized between Desktop and your own server, Nextcloud provides applications for Windows, Linux and Mac desktops and a mobile app for android and iOS. Nextcloud is not just a dropbox clone, it provides additional features like Calendar, Contacts, Schedule tasks, and streaming media with Ampache.In this tutorial, I will show you how to install and configure the latest Nextcloud 10 release on a CentOS 7 server. I will run Nextcloud with a Nginx web server and PHP7-FPM and use MariaDB as the database system.Prerequisite
CentOS 7 64bit
Root privileges on the server

Step 1 - Install Nginx and PHP7-FPM on CentOS 7

Before we start with the Nginx and php7-fpm installation, we have to add the EPEL package repository. Install it with this yum command.yum -y install epel-releaseNow install Nginx from the EPEL repository.yum -y install nginxThen we have to add another repository for php7-fpm. There are several repositories available on the net that provide PHP 7 packages, I will use webtatic here.Add the PHP7-FPM webtatic repository:rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpmNext, install PHP7-FPM and some additional packages for the Nextcloud installation.yum -y install php70w-fpm php70w-cli php70w-gd php70w-mcrypt php70w-mysql php70w-pear php70w-xml php70w-mbstring php70w-pdo php70w-json php70w-pecl-apcu php70w-pecl-apcu-develFinally, check the PHP version from server terminal to verify that PHP installed correctly.php -v

Step 2 - Configure PHP7-FPM

In this step, we will configure php-fpm to run with Nginx. Php7-fpm will run under user nginx and listen on port 9000.Edit the default php7-fpm configuration file with vim.vim /etc/php-fpm.d/www.confIn line 8 and 10, change user and group to 'nginx'.user = nginx
group = nginxIn line 22, make sure php-fpm is running under server port.listen = 127.0.0.1:9000Uncomment line 366-370 to activate the php-fpm system environment variables.env[HOSTNAME] = $HOSTNAME
env[PATH] = /usr/local/bin:/usr/bin:/bin
env[TMP] = /tmp
env[TMPDIR] = /tmp
env[TEMP] = /tmpSave the file and exit the vim editor.Next, create a new directory for the session path in the '/var/lib/' directory, and change the owner to the 'nginx' user.mkdir -p /var/lib/php/session
chown nginx:nginx -R /var/lib/php/session/Now start php-fpm and Nginx, then enable the services to start at boot time.sudo systemctl start php-fpm
sudo systemctl start nginx

sudo systemctl enable php-fpm
sudo systemctl enable nginx

PHP7-FPM configuration is done.

Step 3 - Install and Configure MariaDB

I will use MariaDB for the Nextcloud database. Install the mariadb-server package from the CentOS repository with yum.yum -y install mariadb mariadb-serverStart the MariaDB service and add it to run at boot time.systemctl start mariadb
systemctl enable mariadbNow configure the MariaDB root password.mysql_secure_installationType in your root password when requested.Set root password? [Y/n] Y
New password:
Re-enter new password:

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] YThe MariaDB root password has been set, now we can login to the mysql shell to create a new database and a new user for Nextcloud. I will create a new database named 'nextcloud_db' and a user 'nextclouduser' with password 'nextclouduser@'. Choose a secure password for your installation!mysql -u root -p
Type PasswordType in the mysql query below to create a new database and a new user.create database nextcloud_db;
create user nextclouduser@localhost identified by 'nextclouduser@';
grant all privileges on nextcloud_db.* to nextclouduser@localhost identified by 'nextclouduser@';
flush privileges;

The nextcloud_db database with user 'nextclouduser' has been created.

Step 4 - Generate a Self-signed SSL Certificate for Nextcloud

In this tutorial, I will run nextcloud with a https connection for the client. You can use free SSL such as let's encrypt or create  self signed SSL certificate. I will create my own self-signed SSL certificate file with the OpenSSL command.Create a new directory for the SSL file.mkdir -p /etc/nginx/cert/And generate a new SSL certificate file with the the openssl command below.openssl req -new -x509 -days 365 -nodes -out /etc/nginx/cert/nextcloud.crt -keyout /etc/nginx/cert/nextcloud.keyFinally, change the permission of all certificate files to 600 with chmod.chmod 700 /etc/nginx/cert
chmod 600 /etc/nginx/cert/*

Step 5 - Download and Install Nextcloud

We will download Nextcloud with wget directly to the server, so we have to install wget first. Additionally, we need the unzip program. Install both applications with yum.yum -y install wget unzipGo to the /tmp directory and download latest stable Nextcloud 10 version from the Nextcloud web site with wget.cd /tmp
wget https://download.nextcloud.com/server/releases/nextcloud-10.0.2.zipExtract the nextcloud zip file and move it's content to the '/usr/share/nginx/html/' directory.unzip nextcloud-10.0.2.zip
mv nextcloud/ /usr/share/nginx/html/Next, go to the Nginx web root directory and create a new 'data' directory for Nextcloud.cd /usr/share/nginx/html/
mkdir -p nextcloud/data/Change the owner of the 'nextcloud' directory to the 'nginx' user and group.chown nginx:nginx -R nextcloud/

Step 6 - Configure Nextcloud Virtual Host in Nginx

In step 5 we've downloaded the Nextcloud source code and configured it to run under the Nginx web server. But we still need to configure a virtual host for Nextcloud. Create a new virtual host configuration file 'nextcloud.conf' in the Nginx 'conf.d' directory.cd /etc/nginx/conf.d/
vim nextcloud.confPaste the Nextcloud virtual host configuration below.upstream php-handler {
    server 127.0.0.1:9000;
    #server unix:/var/run/php5-fpm.sock;
}

server {
    listen 80;
    server_name cloud.nextcloud.co;
    # enforce https
    return 301 https://$server_name$request_uri; }

server {
    listen 443 ssl;
    server_name cloud.nextcloud.co;

    ssl_certificate /etc/nginx/cert/nextcloud.crt;
    ssl_certificate_key /etc/nginx/cert/nextcloud.key;
