亲爱的ServerFault社区,
两天前我设法让我的网站进入一个功能齐全的状态..大约3小时前的今天,我重新启动了我的linux盒子,发现我的网站不再工作了.我不知道为什么会这样,而且坦率地说我只是觉得我现在正处于一个水平来修复它 – 我真的可以帮到你:)

基本上我所有的Nginx PHP文件都呈现为空白或说明“Permission Denied”

PHP-FPM前几天工作正常……现在我收到了这个错误!!

我的网站今天重新启动以来一直很好！格儿.

查看我的错误日志,我可以看到：

PHP-FPM配置：

@H_403_15@; Start a new pool named 'www'.
[www]

; The address on which to accept FastCGI requests.
; Valid Syntaxes are:
;   'ip.add.re.ss:port'    - to listen on a TCP socket to a specific address on
;                            a specific port;
;   'port'                 - to listen on a TCP socket to all addresses on a
;                            specific port;
;   '/path/to/unix/socket' - to listen on a unix socket.
; Note: This value is mandatory.
listen = 127.0.0.1:9000

; Set listen(2) backlog. A value of '-1' means unlimited.
; Default Value: -1
;listen.backlog = -1

; List of ipv4 addresses of FastCGI clients which are allowed to connect.
; Equivalent to the FCGI_WEB_SERVER_ADDRS environment variable in the original
; PHP FCGI (5.2.2+). Makes sense only with a tcp listening socket. Each address
; must be separated by a comma. If this value is left blank,connections will be
; accepted from any ip address.
; Default Value: any
listen.allowed_clients = 127.0.0.1

; Set permissions for unix socket,if one is used. In Linux,read/write
; permissions must be set in order to allow connections from a web server. Many
; BSD-derived systems allow connections regardless of permissions.
; Default Values: user and group are set as the running user
;                 mode is set to 0660
;listen.owner = nobody
;listen.group = nobody
;listen.mode = 0660

; Unix user/group of processes
; Note: The user is mandatory. If the group is not set,the default user's group
;       will be used.
; RPM: apache Choosed to be able to access some dir as httpd
user = Nginx
; RPM: Keep a group allowed to write in log dir.
group = Nginx

; Choose how the process manager will control the number of child processes.
; Possible Values:
;   static  - a fixed number (pm.max_children) of child processes;
;   dynamic - the number of child processes are set dynamically based on the
;             following directives:
;             pm.max_children      - the maximum number of children that can
;                                    be alive at the same time.
;             pm.start_servers     - the number of children created on startup.
;             pm.min_spare_servers - the minimum number of children in 'idle'
;                                    state (waiting to process). If the number
;                                    of 'idle' processes is less than this
;                                    number then some children will be created.
;             pm.max_spare_servers - the maximum number of children in 'idle'
;                                    state (waiting to process). If the number
;                                    of 'idle' processes is greater than this
;                                    number then some children will be killed.
; Note: This value is mandatory.
pm = dynamic

; The number of child processes to be created when pm is set to 'static' and the
; maximum number of child processes to be created when pm is set to 'dynamic'.
; This value sets the limit on the number of simultaneous requests that will be
; served. Equivalent to the ApacheMaxClients directive with mpm_prefork.
; Equivalent to the PHP_FCGI_CHILDREN environment variable in the original PHP
; CGI.
; Note: Used when pm is set to either 'static' or 'dynamic'
; Note: This value is mandatory.
pm.max_children = 50

; The number of child processes created on startup.
; Note: Used only when pm is set to 'dynamic'
; Default Value: min_spare_servers + (max_spare_servers - min_spare_servers) / 2
pm.start_servers = 5

; The desired minimum number of idle server processes.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'
pm.min_spare_servers = 5

; The desired maximum number of idle server processes.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'
pm.max_spare_servers = 35

; The number of requests each child process should execute before respawning.
; This can be useful to work around memory leaks in 3rd party libraries. For
; endless request processing specify '0'. Equivalent to PHP_FCGI_MAX_REQUESTS.
; Default Value: 0
;pm.max_requests = 500

; The URI to view the FPM status page. If this value is not set,no URI will be
; recognized as a status page. By default,the status page shows the following
; information:
;   accepted conn    - the number of request accepted by the pool;
;   pool             - the name of the pool;
;   process manager  - static or dynamic;
;   idle processes   - the number of idle processes;
;   active processes - the number of active processes;
;   total processes  - the number of idle + active processes.
; The values of 'idle processes','active processes' and 'total processes' are
; updated each second. The value of 'accepted conn' is updated in real time.
; Example output:
;   accepted conn:   12073
;   pool:             www
;   process manager:  static
;   idle processes:   35
;   active processes: 65
;   total processes:  100
; By default the status page output is formatted as text/plain. Passing either
; 'html' or 'json' as a query string will return the corresponding output
; Syntax. Example:
;   http://www.foo.bar/status
;   http://www.foo.bar/status?json
;   http://www.foo.bar/status?html
; Note: The value must start with a leading slash (/). The value can be
;       anything,but it may not be a good idea to use the .PHP extension or it
;       may conflict with a real PHP file.
; Default Value: not set
;pm.status_path = /status

; The ping URI to call the monitoring page of FPM. If this value is not set,no
; URI will be recognized as a ping page. This could be used to test from outside
; that FPM is alive and responding,or to
; - create a graph of FPM availability (rrd or such);
; - remove a server from a group if it is not responding (load balancing);
; - trigger alerts for the operating team (24/7).
; Note: The value must start with a leading slash (/). The value can be
;       anything,but it may not be a good idea to use the .PHP extension or it
;       may conflict with a real PHP file.
; Default Value: not set
;ping.path = /ping

; This directive may be used to customize the response of a ping request. The
; response is formatted as text/plain with a 200 response code.
; Default Value: pong
;ping.response = pong

; The timeout for serving a single request after which the worker process will
; be killed. This option should be used when the 'max_execution_time' ini option
; does not stop script execution for some reason. A value of '0' means 'off'.
; Available units: s(econds)(default),m(inutes),h(ours),or d(ays)
; Default Value: 0
;request_terminate_timeout = 0

; The timeout for serving a single request after which a PHP backtrace will be
; dumped to the 'slowlog' file. A value of '0s' means 'off'.
; Available units: s(econds)(default),or d(ays)
; Default Value: 0
;request_slowlog_timeout = 0

; The log file for slow requests
; Default Value: not set
; Note: slowlog is mandatory if request_slowlog_timeout is set
slowlog = /var/log/PHP-fpm/www-slow.log

; Set open file descriptor rlimit.
; Default Value: system defined value
;rlimit_files = 1024

; Set max core size rlimit.
; Possible Values: 'unlimited' or an integer greater or equal to 0
; Default Value: system defined value
;rlimit_core = 0

; Chroot to this directory at the start. This value must be defined as an
; absolute path. When this value is not set,chroot is not used.
; Note: chrooting is a great security feature and should be used whenever
;       possible. However,all PHP paths will be relative to the chroot
;       (error_log,sessions.save_path,...).
; Default Value: not set
;chroot =

; Chdir to this directory at the start. This value must be an absolute path.
; Default Value: current directory or / when chroot
;chdir = /var/www

; Redirect worker stdout and stderr into main error log. If not set,stdout and
; stderr will be redirected to /dev/null according to FastCGI specs.
; Default Value: no
;catch_workers_output = yes

; Limits the extensions of the main script FPM will allow to parse. This can
; prevent configuration mistakes on the web server side. You should only limit
; FPM to .PHP extensions to prevent malicIoUs users to use other extensions to
; exectute PHP code.
; Note: set an empty value to allow all extensions.
; Default Value: .PHP
;security.limit_extensions = .PHP .PHP3 .PHP4 .PHP5

; Pass environment variables like LD_LIBRARY_PATH. All $VARIABLEs are taken from
; the current environment.
; Default Value: clean env
;env[HOSTNAME] = $HOSTNAME
;env[PATH] = /usr/local/bin:/usr/bin:/bin
;env[TMP] = /tmp
;env[TMPDIR] = /tmp
;env[TEMP] = /tmp

; Additional PHP.ini defines,specific to this pool of workers. These settings
; overwrite the values prevIoUsly defined in the PHP.ini. The directives are the
; same as the PHP SAPI:
;   PHP_value/PHP_flag             - you can set classic ini defines which can
;                                    be overwritten from PHP call 'ini_set'.
;   PHP_admin_value/PHP_admin_flag - these directives won't be overwritten by
;                                     PHP call 'ini_set'
; For PHP_*flag,valid values are on,off,1,true,false,yes or no.

; Defining 'extension' will load the corresponding shared extension from
; extension_dir. Defining 'disable_functions' or 'disable_classes' will not
; overwrite prevIoUsly defined PHP.ini values,but will append the new value
; instead.

; Default Value: nothing is defined by default except the values in PHP.ini and
;                specified at startup with the -d argument
;PHP_admin_value[sendmail_path] = /usr/sbin/sendmail -t -i -f www@my.domain.com
;PHP_flag[display_errors] = off
PHP_admin_value[error_log] = /var/log/PHP-fpm/www-error.log
PHP_admin_flag[log_errors] = on
;PHP_admin_value[memory_limit] = 128M

; Set session path to a directory owned by process user
PHP_value[session.save_handler] = files
PHP_value[session.save_path] = /var/lib/PHP/session
