各种可能出现的坑

永恒重点注意

权限!权限!权限!
以下目录的权限必须注意

/etc/phpMyAdmin

$ sudo chgrp -R nginx /etc/phpMyAdmin

/data/www/pma

$ sudo chown -R nginx:nginx /data/www/pma

/data/sessions

$ mkdir -p /data/sessions
$ sudo chown -R nginx:nginx /data/sessions
$ sudo chmod 777 /data/sessions

/var/lib/phpMyadmin

$ sudo chown -R nginx:nginx /var/lib/phpMyAdmin/

确保 /var/run/php-fpm/php-fpm.sock存在

有问题的时候查找log

$ cat /var/log/www.access.log
