php-fpm error "no input file specified" with Docker

Question

I am trying to setup a docker container for php-fpm. But encountering this error when visiting the web directory configured on localhost. I have been stuck here for over 5 hours. Here is my Dockerfile:

FROM centos:latest WORKDIR /tmp RUN yum -y update RUN rpm -Uvh https://mirror.webtatic.com/yum/el7/epel-release.rpm; rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm #RUN yum -y groupinstall "Development Tools" RUN systemctl stop firewalld; systemctl disable firewalld RUN yum -y install php56w php56w-opcache php56w-cli php56w-common php56w-devel php56w-fpm php56w-gd php56w-mbstring php56w-mcrypt php56w-pdo php56w-mysqlnd php56w-pecl-xdebug php56w-pecl-memcache RUN sed -i "s/;date.timezone =.*/date.timezone = UTC/" /etc/php.ini && \ sed -i "s/display_errors = Off/display_errors = stderr/" /etc/php.ini && \ sed -i "s/upload_max_filesize = 2M/upload_max_filesize = 30M/" /etc/php.ini && \ sed -i -e "s/;daemonize\s*=\s*yes/daemonize = no/g" /etc/php-fpm.conf && \ sed -i '/^listen = /c listen = 9000' /etc/php-fpm.d/www.conf && \ sed -i '/^listen.allowed_clients/c ;listen.allowed_clients =' /etc/php-fpm.d/www.conf RUN mkdir -p /home/www VOLUME ["/home/www"] EXPOSE 9000 ENTRYPOINT ["/usr/sbin/php-fpm", "-F"]

Check by docker ps

aab4f8ce0fe8 jason/fpm:v1 "/usr/sbin/php-fpm - 6 minutes ago Up 6 minutes 0.0.0.0:9002->9000/tcp fpm

The data volume does exist. check by docker inspect

"Volumes": { "/home/www": "/home/www" }, "VolumesRW": { "/home/www": true } "Ports": { "9000/tcp": [ { "HostIp": "0.0.0.0", "HostPort": "9002" } ] }

localhost nginx website config:

listen 80; server_name admin.local.lumen.com; index index.php index.html index.htm ; root /home/www/lumenback/public_admin; error_log /home/wwwlogs/lumenback_error.log; location / { try_files $uri $uri/ /index.php?$query_string; } location ~ .*\.php?$ { fastcgi_pass 127.0.0.1:9002; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; #include fastcgi.conf; }

Error logged by php-fpm:

[error] 5322#0: *3798 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 172.16.1.19, server: admin.local.lumen.com, request: "GET /favicon.ico HTTP/1.1", upstream: "fastcgi://127.0.0.1:9002", host: "admin.local.lumen.com"

Many people online said the error is caused by fastcgi_param SCRIPT_FILENAME. Seems it is not the reason in my case.

it seems this error is related to something wrong in SCRIPT_FILENAME, can you docker exec -it aab4f8ce0fe8 echo $SCRIPT_FILENAME and paste it? — user2915097

@user2915097 It prints nothing. I think $SCRIPT_FILENAME is not an env variable — JasonW

Have you tried include fastcgi_params first then set SCRIPT_FILENAME? — xuhdev

Maybe you should check permissions. Try to change all php files to world readable and try again — xuhdev

@xuhdev Thanks. I changed data volume to a different directory with permission 755 and put fastcgi_params before SCRIPT_FILENAME. Now it works. Then I changed fastcgi_params back, still works. I guess the reason is the incorrect permission. — JasonW

You may have got an incorrect file permission -- the process in the container cannot read php files. You can either change the php files readable by the user running php-fpm in the container. Note that the user name in the container differs from the names on the host, so specifying user ID is probably a better way (or simply make them world readable).
