我决定将我的OP从Litespeed改为Nginx因为我读了很多关于Nginx会花费的资源.
我在线运行一个有500个用户的Wordpress网站
好的,谢谢大家的帮助:)我编辑了一些东西.
我也有一些问题：
我必须删除;在下午之前.设置？我删除了什么配置？我在/etc/php5/fpm中有两个快速的cgi,一个名为php-fpm.conf,一个在/etc/php5/fpm/pool.d中,名为www.conf？
我在晚上尝试了新的配置,当我醒来时,我已经有了一个空白页面.最佳：

我认为cpu的使用率现在已经降低了,但这并没有解决崩溃问题……
我的配置现在是：php-fpm.conf
;;;;;;;;;;;;;;;;;;;;; ; FPM Configuration ; ;;;;;;;;;;;;;;;;;;;;; ; All relative paths in this configuration file are relative to PHP's install ; prefix (/usr). This prefix can be dynamicaly changed by using the ; '-p' argument from the command line. ; Include one or more files. If glob(3) exists,it is used to include a bunch of ; files from a glob(3) pattern. This directive can be used everywhere in the ; file. ; Relative path can also be used. They will be prefixed by: ; - the global prefix if it's been set (-p arguement) ; - /usr otherwise ;include=/etc/php5/fpm/*.conf ;;;;;;;;;;;;;;;;;; ; Global Options ; ;;;;;;;;;;;;;;;;;; [global] ; Pid file ; Note: the default prefix is /var ; Default Value: none pid = /var/run/php5-fpm.pid ; Error log file ; If it's set to "syslog",log is sent to syslogd instead of being written ; in a local file. ; Note: the default prefix is /var ; Default Value: log/php-fpm.log error_log = /var/log/php5-fpm.log ; syslog_facility is used to specify what type of program is logging the ; message. This lets syslogd specify that messages from different facilities ; will be handled differently. ; See syslog(3) for possible values (ex daemon equiv LOG_DAEMON) ; Default Value: daemon ;syslog.facility = daemon ; syslog_ident is prepended to every message. If you have multiple FPM ; instances running on the same server,you can change the default value ; which must suit common needs. ; Default Value: php-fpm ;syslog.ident = php-fpm ; Log level ; Possible Values: alert,error,warning,notice,debug ; Default Value: notice ;log_level = notice ; If this number of child processes exit with SIGSEGV or SIGBUS within the time ; interval set by emergency_restart_interval then FPM will restart. A value ; of '0' means 'Off'. ; Default Value: 0 emergency_restart_threshold = 1 ; Interval of time used by emergency_restart_interval to determine when ; a graceful restart will be initiated. This can be useful to work around ; accidental corruptions in an accelerator's shared memory. ; Available Units: s(econds),m(inutes),h(ours),or d(ays) ; Default Unit: seconds ; Default Value: 0 emergency_restart_interval = 1s ; Time limit for child processes to wait for a reaction on signals from master. ; Available units: s(econds),or d(ays) ; Default Unit: seconds ; Default Value: 0 process_control_timeout = 10s ; The maximum number of processes FPM will fork. This has been design to control ; the global number of processes when using dynamic PM within a lot of pools. ; Use it with caution. ; Note: A value of 0 indicates no limit ; Default Value: 0 process.max = 150 ; Send FPM to background. Set to 'no' to keep FPM in foreground for debugging. ; Default Value: yes ;daemonize = yes ; Set open file descriptor rlimit for the master process. ; Default Value: system defined value rlimit_files = 1024 ; Set max core size rlimit for the master process. ; Possible Values: 'unlimited' or an integer greater or equal to 0 ; Default Value: system defined value ;rlimit_core = 0 ; Specify the event mechanism FPM will use. The following is available: ; - select (any POSIX os) ; - poll (any POSIX os) ; - epoll (linux >= 2.5.44) ; - kqueue (FreeBSD >= 4.1,OpenBSD >= 2.9,NetBSD >= 2.0) ; - /dev/poll (Solaris >= 7) ; - port (Solaris >= 10) ; Default Value: not set (auto detection) ; events.mechanism = epoll ;;;;;;;;;;;;;;;;;;;; ; Pool Definitions ; ;;;;;;;;;;;;;;;;;;;; ; Multiple pools of child processes may be started with different listening ; ports and different management options. The name of the pool will be ; used in logs and stats. There is no limitation on the number of pools which ; FPM can handle. Your system will tell you anyway :) ; To configure the pools it is recommended to have one .conf file per ; pool in the following directory: include=/etc/php5/fpm/pool.d/*.conf request_terminate_timeout = 30s pm.max_children = 25 ; 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 = 2 ; 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 = 5 ; 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;

目前尚不清楚您是否正在使用像APC这样的操作码cacher.首先,启用它.调整内存以避免碎片.另外,使用socket,而不是从nginx到php5-fpm的http连接,并将该套接字放在/ dev / shm上.
在nginx中,使用fastcgi_pass unix：/dev/shm/php5-fpm.sock ;,并相应地更改php5-fpm的配置.
在nginx中,使用fastcgi_pass unix：/dev/shm/php5-fpm.sock ;,并相应地更改php5-fpm的配置.
尝试将pm.max_children降低到30-40-50-60之间的更逼真的状态,并使用free -m查看负载和空闲内存.查看客户端是否收到任何502/504错误.相应地降低pm.start_servers,min和max_spare(15,5,25).
如果有很多匿名用户,请考虑使用任何缓存插件,如WP-FFPC,WP Super Cache或类似的wordpress.
如果在nginx中启用了gzip,请禁用gzipping.
也许您需要在nginx中调整fastcgi_buffer_size和fastcgi_buffers选项.
检查您是否在Mysql上启用了查询缓存并且已经足够.
在网站上安装了像munin这样的监控系统,以检查负载/内存消耗/延迟等.
