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.
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:
- top - 13:55:27 up 1 day,19:28,2 users,load average: 0.18,0.36,0.19
- Tasks: 84 total,1 running,83 sleeping,0 stopped,0 zombie

- PID USER PR NI VIRT RES SHR S %cpu %MEM TIME+ COMMAND

- 2 root 20 0 0 0 0 S 0 0.0 0:00.00 kthreadd
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'

- 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'

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.
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.
