php-fpm优化

1.通常情况我们修改/etc/php.ini文件，仅会修改错误日志与文件上传

4expose_php = Off # 关闭php版本信息

14file_uploads = On # 开启文件上传功能，默认启动

15upload_max_filesize = 300M # 允许上传文件的最大大小

16post_max_size = 300M # 允许客户端单个POST请求发送的最大数据

17max_file_uploads = 20 # 允许同时上传的文件的最大数量

18memory_limit = 128M # 每个脚本执行最大内存

20#/etc/php.ini优化配置如下

21sql.safe_mode = Off

22post_max_size = 300M

23upload_max_filesize = 300M

24max_file_uploads = 20

25memory_limit = 128M

26date.timezone = Asia/Shanghai

27

28expose_php = Off

29display_error = Off

30error_reporting = E_WARNING & E_ERROR

31log_errors = On

32error_log = /var/log/php_error.log

20; Choose how the process manager will control the number of child processes.

21; Possible Values:

22; static - a fixed number (pm.max_children) of child processes;

23; dynamic - the number of child processes are set dynamically based on the

24; following directives:

25; pm.max_children - the maximum number of children that can

26; be alive at the same time.

27; pm.start_servers - the number of children created on startup.

28; pm.min_spare_servers - the minimum number of children in 'idle'

29; state (waiting to process). If the number

30; of 'idle' processes is less than this

31; number then some children will be created.

32; pm.max_spare_servers - the maximum number of children in 'idle'

33; state (waiting to process). If the number

34; of 'idle' processes is greater than this

35; number then some children will be killed.

36; Note: This value is mandatory.

38pm = dynamic #

39pm.max_children = 512 #最大启动的php-fpm进程数

40pm.start_servers = 32 #初始启动的php-fpm进程数

41pm.min_spare_servers = 32 #最少的空闲php-fpm进程数

42pm.max_spare_servers = 64 #最大的空闲php-fpm进程数

43pm.max_requests = 1500 #每一个进程能响应的请求数

44pm.process_idle_timeout = 15s;

46# 错误日志

47php_flag[display_errors] = off

48php_admin_value[error_log] = /soft/log/php/php-www_error.log

49php_admin_flag[log_errors] = on

17pool #fpm池名称,大多数为www

18process manager #进程管理方式dynamic或者static

19start time #启动日志,如果reload了fpm，时间会更新

20start since #运行时间

21accepted conn #当前池接受的请求数

22listen queue #请求等待队列,如果这个值不为0,那么需要增加FPM的进程数量

23max listen queue #请求等待队列最高的数量

24listen queue len #socket等待队列长度

25idle processes #空闲进程数量

26active processes #活跃进程数量

27total processes #总进程数量

28max active processes #最大的活跃进程数量（FPM启动开始计算）

29max children reached #程最大数量限制的次数，如果这个数量不为0，那说明你的最大进程数量过小,可以适当调整。
