apacheは使わないのでアクセスが増えてもメモリを食い潰すことはない。
デフォルトで100Mほど節約できた(php-fpmのプロセスが5の時の場合、以下の設定だと10までプロセスが増える。phpに対するアクセス以外はnginxにまかせているのでこれくらいでいけると思う)
はまりポイントはLive Commerceがhtmlを使うので、nginxはhtmlを処理しないようにすること。
epelとremiリポジトリからインストールする(Centos5.5 32bit)
rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-4.noarch.rpm/home/htdocs/www.example.com/master以下にLiveCommerceをインストールする

; 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 0666 ;listen.owner = nobody ;listen.group = nobody ;listen.mode = 0666 ; 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 = apache ; RPM: Keep a group allowed to write in log dir. group = apache ; 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 = 10 ; 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 = 10 ; 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), m(inutes), h(ours), 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 ; 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, 0, 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] = 32M
