我已经尝试了两天来升级我的常规 LAMP 堆栈以使用 php5-fpm 和 event-mpm，但就是不起作用！目前看来我已经尝试了一切方法让它工作，但无济于事。
当我查看我的活动进程时，Apache2 和 php5-fpm 似乎都运行良好，但在我的 error.log 中，我发现了数百行错误。见下文：

/etc/php5/fpm/pool.d/www.conf
; Start a new pool named 'www'.
; the variable $pool can we used in any directive and will be replaced by the
; pool name ('www' here)
[www]
; Per pool prefix
; It only applies on the following directives:
; - 'slowlog'
; - 'listen' (unixsocket)
; - 'chroot'
; - 'chdir'
; - 'php_values'
; - 'php_admin_values'
; When not set, the global prefix (or /usr) applies instead.
; Note: This directive can also be relative to the global prefix.
; Default Value: none
;prefix = /path/to/pools/$pool
; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's group
; will be used.
user = www-data
group = www-data
; 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 = /var/run/php5-fpm.sock
; Set listen(2) backlog.
; Default Value: 65535 (-1 on FreeBSD and OpenBSD)
;listen.backlog = 65535
; 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 = www-data
listen.group = www-data
listen.mode = 0666
; 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
; Specify the nice(2) priority to apply to the pool processes (only if set)
; The value can vary from -19 (highest priority) to 20 (lower priority)
; Note: - It will only work if the FPM master process is launched as root
; - The pool processes will inherit the master process priority
; unless it specified otherwise
; Default Value: no set
; priority = -19
; 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. With this process management, there will be
; always at least 1 children.
; 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.
; ondemand - no children are created at startup. Children will be forked when
; new requests will connect. The following parameter are used:
; pm.max_children - the maximum number of children that
; can be alive at the same time.
; pm.process_idle_timeout - The number of seconds after which
; an idle process 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 when pm is set to 'dynamic' or 'ondemand'.
; 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. The below defaults are based on a server without much resources. Don't
; forget to tweak pm.* to fit your needs.
; Note: Used when pm is set to 'static', 'dynamic' or 'ondemand'
; Note: This value is mandatory.
pm.max_children = 5
; 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 = 2
; 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 = 1
; 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 = 3
; The number of seconds after which an idle process will be killed.
; Note: Used only when pm is set to 'ondemand'
; Default Value: 10s
;pm.process_idle_timeout = 10s;
; 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. It shows the following informations:
; pool - the name of the pool;
; process manager - static, dynamic or ondemand;
; start time - the date and time FPM has started;
; start since - number of seconds since FPM has started;
; accepted conn - the number of request accepted by the pool;
; listen queue - the number of request in the queue of pending
; connections (see backlog in listen(2));
; max listen queue - the maximum number of requests in the queue
; of pending connections since FPM has started;
; listen queue len - the size of the socket queue of pending connections;
; idle processes - the number of idle processes;
; active processes - the number of active processes;
; total processes - the number of idle + active processes;
; max active processes - the maximum number of active processes since FPM
; has started;
; max children reached - number of times, the process limit has been reached,
; when pm tries to start more children (works only for
; pm 'dynamic' and 'ondemand');
; Value are updated in real time.
; Example output:
; pool: www
; process manager: static
; start time: 01/Jul/2011:17:53:49 +0200
; start since: 62636
; accepted conn: 190460
; listen queue: 0
; max listen queue: 1
; listen queue len: 42
; idle processes: 4
; active processes: 11
; total processes: 15
; max active processes: 12
; max children reached: 0
;
; By default the status page output is formatted as text/plain. Passing either
; 'html', 'xml' or 'json' in the 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
; http://www.foo.bar/status?xml
;
; By default the status page only outputs short status. Passing 'full' in the
; query string will also return status for each pool process.
; Example:
; http://www.foo.bar/status?full
; http://www.foo.bar/status?json&full
; http://www.foo.bar/status?html&full
; http://www.foo.bar/status?xml&full
; The Full status returns for each process:
; pid - the PID of the process;
; state - the state of the process (Idle, Running, ...);
; start time - the date and time the process has started;
; start since - the number of seconds since the process has started;
; requests - the number of requests the process has served;
; request duration - the duration in µs of the requests;
; request method - the request method (GET, POST, ...);
; request URI - the request URI with the query string;
; content length - the content length of the request (only with POST);
; user - the user (PHP_AUTH_USER) (or '-' if not set);
; script - the main script called (or '-' if not set);
; last request cpu - the %cpu the last request consumed
; it's always 0 if the process is not in Idle state
; because CPU calculation is done when the request
; processing has terminated;
; last request memory - the max amount of memory the last request consumed
; it's always 0 if the process is not in Idle state
; because memory calculation is done when the request
; processing has terminated;
; If the process is in Idle state, then informations are related to the
; last request the process has served. Otherwise informations are related to
; the current request being served.
; Example output:

答案1
mod_fastcgi占用大量内存，并且通常难以设置。您或许应该尝试使用 进行设置mod_proxy_fcgi，这是 Apache 2.4 中新推出的功能，专门用于此类用例。Apache wiki 中有关 PHP-FPM 的条目有一些很好的入门指导。
这mod_proxy_fcgi文档还包括设置 PHP-FPM 的具体示例以及PHP 文档还有有用的信息。
还请注意（尽管有些错误引用相反），直到 Apache 2.4.10（2.4.9 尚未真正发布）版本才可以使用 unix 套接字，因此您无法在 2.4.7 下使用它们。
