Piwik couldn't write to some directories (1 reply)

Hi,

Could you please help me with this situation. I just installed Piwik to fresh LEMP server (OpenLogic 7^*, MariaDB, Nginx^**, PHP-FPM)
^*) CentOS based and hosted in Azure
^**) epel-release

MariaDB, Nginx and PHP works fine as tested with web site with simple functionality.

Piwik is currently installed to location /usr/share/nginx/html/piwik by commands:

cd /usr/share/nginx/html
wget http://builds.piwik.org/piwik.zip
unzip piwik.zip
mkdir piwik/tmp
chmod 0755 -R /usr/share/nginx/html/piwik
chown -R nginx:nginx /usr/share/nginx/html/piwik

But no matter what I do still got error message in Piwik page. I have done hours of searching with Google but no solution found yet. Error message is clear but I don't know what to do anymore:
Piwik couldn't write to some directories (running as user 'nginx').
Try to Execute the following commands on your server, to allow Write access on these directories:
chown -R nginx:nginx /usr/share/nginx/html/piwik
chmod -R 0755 /usr/share/nginx/html/piwik/tmp
chmod -R 0755 /usr/share/nginx/html/piwik/tmp/assets/
chmod -R 0755 /usr/share/nginx/html/piwik/tmp/cache/
chmod -R 0755 /usr/share/nginx/html/piwik/tmp/logs/
chmod -R 0755 /usr/share/nginx/html/piwik/tmp/tcpdf/
chmod -R 0755 /usr/share/nginx/html/piwik/tmp/templates_c/
If this doesn't work, you can try to create the directories with your FTP software, and set the CHMOD to 0755 (or 0777 if 0755 is not enough). To do so with your FTP software, right click on the directories then click permissions.

Permissions listed and even given chmod 777 to tmp and config folder:

Nginx, MariaDB and PHP-FPM installation shortly:

yum install nginx -y
systemctl start nginx 
systemctl enable nginx

yum install php php-common php-fpm php-mysql -y
systemctl start php-fpm
systemctl enable php-fpm

yum install mariadb-server mariadb -y
mysql_secure_installation
mysql -u root -p
MariaDB [(none)]> CREATE DATABASE piwik;
MariaDB [(none)]> CREATE USER 'piwik'@'localhost' IDENTIFIED BY 'password_here';
MariaDB [(none)]> GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, ALTER, CREATE TEMPORARY TABLES, LOCK TABLES ON piwik.* TO 'piwik'@'localhost';

systemctl restart mariadb

/etc/nginx/nginx.conf:

user    nginx;
worker_processes 1;
..
index	 index.php index.html index.htm;
...
server {
        listen       80;
        server_name  localhost;
        root         /usr/share/nginx/html;
...		
location ~ \.php$ {
            root           /usr/share/nginx/html;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        fastcgi_params;
        }

/etc/php.ini:

cgi.fix_pathinfo=0

/etc/php-fpm.d/www.conf:

user = nginx
group = nginx
listen = 127.0.0.1:9000

And finally:

systemctl restart nginx
systemctl restart php-fpm

I will add usage of Unix sockets (listen = /var/run/php-fpm/php-fpm.sock to /etc/php-fpm.d/www.conf) when basic installation works.
