Fixing Nginx 413 Request Entity Too Large

Problems after moving to a new server

1.Sessions are stored by default in/tmp/session(change this in php-fpm.conf); check whether the configured session path is correct.

2.File uploads return413 Request Entity Too Large

• Find the active Nginx configuration(whereis nginx.conf)
• Find the http{} section and change it toclient_max_body_size 800m; the default should be 2m.

3.Change the defaults in php.ini

• post_max_size = 800M(default: 2M);
• upload_max_filesize = 800M(default: 2M);

4. Restart Nginx and php-fpm

• kill -HUP 'cat /usr/local/nginx/nginx.pid'
• Restart php-fpm

5.If single sign-on keeps failing to authenticate, encryption-function extensions may be missing(mcrypt、mbstring)
