lnmp之php-fpm+nginx+ulimit的综合设置之故障排除

相信其它的地方大家都懂，这里重点说下面粗体注释标注部分 参数设置必须与系统的 ulimit -Sn 参数一致，并且 php-fpm.conf,nginx,conf中的设置要一致，否则会出现诸多历史遗留问题以及不和谐的ERROR WRING问题

以下是nginx.conf里的一些 配置信息，重点说红色部分

PHP-FPM中的rlimit_files参数设置需同系统参数一致且同nginx 里的connections，rlimit参数相呼应，否则大流量并发下会出现如5xx,4xx等意象不到的错误状态

（这里只说红色粗体部分，其它的日后再解，相信大家一定也都懂得其它参数的设置）

; 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;

; 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,

; By default the status page output is formatted as text/plain. Passing either

; 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:

; 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.

; Note: relative path can be used.

; 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.

; Note: on highloaded environement, this can cause some delay in the page

; process time (several ms).

; Default Value: no

;catch_workers_output = yes

; Clear environment in FPM workers

; Prevents arbitrary environment variables from reaching FPM worker processes

; by clearing the environment in workers before env vars specified in this

; pool configuration are added.

; Setting to "no" will make all environment variables available to PHP code

; via getenv(), $_ENV and $_SERVER.

; Default Value: yes

;clear_env = no

; Limits the extensions of the main script FPM will allow to parse. This can

; prevent configuration mistakes on the web server side. You should only limit

; FPM to .php extensions to prevent malicious users to use other extensions to

; exectute php code.

; Note: set an empty value to allow all extensions.

; Default Value: .php

;security.limit_extensions = .php .php3 .php4 .php5



; 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.

; Note: path INI options can be relative and will be expanded with the prefix

; (pool, global or /usr/local/php)

; 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/fpm-php.www.log

;php_admin_flag[log_errors] = on

;php_admin_value[memory_limit] = 32M

下面说说出现的错误和一些情况：

nginx connections ,rlimits 跟php-fpm的rlimit_files 的参数配置 要与ulimit -n系统参数的连接数配置一致

如果系统 参数比nginx 设置小的话 会出现 4XX,5xx错误，

还有 就是刚编译好的系统环境 默认ulimit -Sn 参数值只有 1024 个，1024 不能满足NGINX需求 测试并发时候怎么测试到了1024以后就4XX,5XX错误了，最后修改了系统内核参数 为16位 二进制最大数 也就是 65535

failed to ptrace(PEEKDATA) pid 20160: Input/output error

php-fpm的rlimit_files参数 如果比系统的ulimit 小的话出现如上这个ERROR

nginx的参数设置如果比系统ulimit -sn 的参数值小的 话nginx 容易出现 5xx 错误

解决方案就是统一修改 php-fpm.conf,nginx.conf,与系统ulimit -sn 的 参数一致，如果 系统ulimt 的默认参数是1024的话，一定要修改掉他，修改为65535 即可，同时php-fpm,nginx的rlimit 参数也要与其一致……
