php-fpm的pool

● php-fpm的pool,在ps aux的時(shí)候在右側(cè)可以看到那一列，php-fpm的pool,也就是php-fpm的池子.

成都創(chuàng)新互聯(lián)公司是一家集網(wǎng)站建設(shè),翠屏企業(yè)網(wǎng)站建設(shè),翠屏品牌網(wǎng)站建設(shè),網(wǎng)站定制,翠屏網(wǎng)站建設(shè)報(bào)價(jià),網(wǎng)絡(luò)營(yíng)銷(xiāo),網(wǎng)絡(luò)優(yōu)化,翠屏網(wǎng)站推廣為一體的創(chuàng)新建站企業(yè)，幫助傳統(tǒng)企業(yè)提升企業(yè)形象加強(qiáng)企業(yè)競(jìng)爭(zhēng)力。可充分滿足這一群體相比中小企業(yè)更為豐富、高端、多元的互聯(lián)網(wǎng)需求。同時(shí)我們時(shí)刻保持專業(yè)、時(shí)尚、前沿，時(shí)刻以成就客戶成長(zhǎng)自我，堅(jiān)持不斷學(xué)習(xí)、思考、沉淀、凈化自己，讓我們?yōu)楦嗟钠髽I(yè)打造出實(shí)用型網(wǎng)站。

●在php-fpm.conf里面定義了一個(gè)池子，支持定義多個(gè)池子，每個(gè)池子可以監(jiān)聽(tīng)不同sock或tcp.例如Nginx有多個(gè)站點(diǎn)，每個(gè)站點(diǎn)都可以使用不同pool.如果Nginx有多個(gè)站點(diǎn)都使用一個(gè)pool的話，假如出現(xiàn)了502的，出現(xiàn)在502狀態(tài)碼，有可能是因?yàn)閜hp資源不夠，那么所有的站點(diǎn)都502，但是如果Nginx每個(gè)站點(diǎn)使用單獨(dú)pool,其中一個(gè)站點(diǎn)502了，但不會(huì)影響到其他站點(diǎn).

● 新增加一個(gè)pool

[root@root-01 etc]# vim php-fpm.conf [global] pid = /usr/local/php-fpm/var/run/php-fpm.pid error_log = /usr/local/php-fpm/var/log/php-fpm.log [www] #listen = /tmp/php-fcgi.sock listen = 127.0.0.1:9000 listen.mode = 666 user = php-fpm group = php-fpm pm = dynamic pm.max_children = 50 pm.start_servers = 20 pm.min_spare_servers = 5 pm.max_spare_servers = 35 pm.max_requests = 500 rlimit_files = 1024 [Anna.com] --->新增加的pool listen = /tmp/Anna.sock #listen = 127.0.0.1:9000 listen.mode = 666 user = php-fpm group = php-fpm pm = dynamic pm.max_children = 50 pm.start_servers = 20 pm.min_spare_servers = 5 pm.max_spare_servers = 35 pm.max_requests = 500 rlimit_files = 1024

● 保存退出，檢查一下語(yǔ)法是否有誤,并重啟php-fpm

[root@root-01 ~]# /usr/local/php-fpm/sbin/php-fpm -t [16-Aug-2017 10:41:56] NOTICE: configuration file /usr/local/php-fpm/etc/php-fpm.conf test is successful [root@root-01 ~]# /etc/init.d/php-fpm restart Gracefully shutting down php-fpm . done Starting php-fpm done

● 重啟php-fpm后ps aux |grep php-fpm，會(huì)發(fā)現(xiàn)多了Anna.com的pool

● 現(xiàn)在有兩個(gè)pool，在test.conf.com站點(diǎn)監(jiān)聽(tīng)是127.0.0.1:9000，現(xiàn)在就把a(bǔ)aa.com.conf定義為Anna.com，這樣的話這樣兩個(gè)站點(diǎn)就隔離開(kāi)了.

[root@root-01 vhost]# vim aaa.com.conf server { listen 80 default_server; server_name aaa.com; index index.html index.htm index.php; root /data/www/default; location ~ .php$ { include fastcgi_params; fastcgi_pass unix:/tmp/Anna.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /data/www/default$fastcgi_script_name; } } 說(shuō)明 假如test.conf.com很忙，請(qǐng)求量很大，將php-fpm進(jìn)程耗盡，最多可以啟動(dòng)50個(gè)進(jìn)程，所有的進(jìn)程都在忙，當(dāng)再來(lái)一個(gè)新的請(qǐng)求的時(shí)候，就會(huì)出現(xiàn)了502，因?yàn)闆](méi)有多余的php-fpm進(jìn)程提供服務(wù).但aaa.com.conf并不會(huì)受影響，因?yàn)槭褂玫氖橇硗庖粋€(gè)pool，這就是建立多個(gè)pool的好處.

●在/usr/local/nginx/conf/nginx.conf里面定義了include vhost/.conf，在php-fpm.conf也是支持的，現(xiàn)在php-fpm.conf主配置文件里面也加include = etc/php-fpm.d/.conf.

[root@root-01 ~]# vim /usr/local/php-fpm/etc/php-fpm.conf [global] pid = /usr/local/php-fpm/var/run/php-fpm.pid [global] pid = /usr/local/php-fpm/var/run/php-fpm.pid error_log = /usr/local/php-fpm/var/log/php-fpm.log include = etc/php-fpm.d/*.conf

● 在/usr/local/php-fpm/etc/目錄下面創(chuàng)建配置文件目錄和子配置文件.

[root@root-01 ~]# cd /usr/local/php-fpm/etc/ [root@root-01 etc]# ls pear.conf php-fpm.conf php-fpm.conf2 php.ini [root@root-01 etc]# mkdir php-fpm.d [root@root-01 etc]# cd php-fpm.d [root@root-01 php-fpm.d]# touch www.conf [root@root-01 php-fpm.d]# touch Anna.conf

● 把/usr/local/php-fpm/etc/php-fpm.conf 里面的兩個(gè)pool分別剪貼到www.conf&Anna.conf

[root@root-01 php-fpm.d]# vim www.conf [www] #listen = /tmp/php-fcgi.sock listen = 127.0.0.1:9000 listen.mode = 666 user = php-fpm group = php-fpm pm = dynamic pm.max_children = 50 pm.start_servers = 20 pm.min_spare_servers = 5 pm.max_spare_servers = 35 pm.max_requests = 500 rlimit_files = 1024 [root@root-01 php-fpm.d]# vim Anna.conf [Anna.com] listen = /tmp/Anna.sock #listen = 127.0.0.1:9000 listen.mode = 666 user = php-fpm group = php-fpm pm = dynamic pm.max_children = 50 pm.start_servers = 20 pm.min_spare_servers = 5 pm.max_spare_servers = 35 pm.max_requests = 500 rlimit_files = 1024 [root@root-01 php-fpm.d]# ls Anna.conf www.conf

● 檢查語(yǔ)法是否有誤&重啟php-fpm，在ps aux |grep php-fpm查看是效果是一樣的，只不過(guò)這樣會(huì)更加清晰.

前言：php-fpm慢執(zhí)行日志，在日常工作中使用的非常多，可以幫助我們快速追查到問(wèn)題點(diǎn).

● 做PHP網(wǎng)站，建議使用lnmp,其中有一個(gè)原因就是我們可以去分析PHP的慢執(zhí)行日志，為什么要分析PHP的慢執(zhí)行日志呢？在運(yùn)維工作中，經(jīng)常會(huì)遇到一個(gè)很讓頭痛的問(wèn)題，公司老板或客戶經(jīng)常反饋公司網(wǎng)站訪問(wèn)慢.為什么會(huì)慢？運(yùn)維人員要知道根本原因，要知道慢在哪個(gè)地方.PHP網(wǎng)站是有辦法指定慢在哪里.

服務(wù)器負(fù)載高，我們可以使用free,top等命令去查看，可以知道到底是哪個(gè)進(jìn)程導(dǎo)致負(fù)載高. 種種跡象表明php-fpm進(jìn)程占用了很多資源，但是并不知道為什么php-fpm在做什么，那么有php慢執(zhí)行日志我們就可以查看到問(wèn)題點(diǎn)，所以php慢執(zhí)行日志非常重要.

● 現(xiàn)在針對(duì)ww.conf做一些配置

[root@root-01 php-fpm.d]# vim www.conf [www] #listen = /tmp/php-fcgi.sock listen = 127.0.0.1:9000 listen.mode = 666 user = php-fpm group = php-fpm pm = dynamic pm.max_children = 50 pm.start_servers = 20 pm.min_spare_servers = 5 pm.max_spare_servers = 35 pm.max_requests = 500 rlimit_files = 1024 加入這行配置： request_slowlog_timeout = 1 --->請(qǐng)求慢日志超過(guò)1秒鐘，就會(huì)記錄日志 slowlog = /usr/local/php-fpm/var/log/www.slow.log --->定義日志路徑

● 保存退出后，檢查語(yǔ)法是否有誤，并重新加載php-fpm,在查看/usr/local/php-fpm/var/log/目錄下是否有生成www.slow.log日志文件

[root@root-01 ~]# /etc/init.d/php-fpm reload Reload service php-fpm done [root@root-01 ~]# ls /usr/local/php-fpm/var/log/www.slow.log /usr/local/php-fpm/var/log/www.slow.log [root@root-01 ~]# ls /usr/local/php-fpm/var/log/ php-fpm.log www.slow.log

●模擬一個(gè)慢執(zhí)行的PHP，寫(xiě)一個(gè)腳本，www這個(gè)pool是test.com.conf站點(diǎn)在使用，所以要針對(duì)這個(gè)站點(diǎn)做操作. 在/data/www/test.com/目錄下寫(xiě)一個(gè)sleep.php的腳本

[root@root-01 ~]# vim /data/www/test.com/sleep.php ~ <?php echo "test slow log"; sleep(2); echo "done"; ?> 說(shuō)明 這腳本是要在執(zhí)行的停2秒，因?yàn)樵谂渲脀ww.conf文件請(qǐng)求慢日志超過(guò)1秒鐘，就會(huì)記錄日志.

● 使用curl來(lái)測(cè)試一下，然后再查看www.slow.log日志

[root@root-01 ~]# curl -x127.0.0.1:80 test.com/sleep.php test slow logdone[root@root-01 ~]# [root@root-01 ~]# cat /usr/local/php-fpm/var/log/www.slow.log [16-Aug-2017 12:30:32] [pool www] pid 3068 script_filename = /data/www/test.com/sleep.php [0x00007f40307e52e8] sleep() /data/www/test.com/sleep.php:3 說(shuō)明 script_filename = /data/www/test.com/sleep.php ---> 這行是告訴我們執(zhí)行慢慢在哪里. [0x00007f40307e52e8] sleep() /data/www/test.com/sleep.php:3 -->慢在具體哪一行. 說(shuō)明 這就是php慢執(zhí)行日志的好處. 12.23 open_basedir

前言：open_basedir的目的就是安全，

● php-fpm也是可以定義open_basedir，之前講過(guò)在php.ini中去定義，如果服務(wù)器上有多個(gè)網(wǎng)站，在php.ini里面去定義就不合適了.要么在Apache虛擬主機(jī)里面配置，要么在php-fpm里面配置，我們可以根據(jù)不同的pool去定義open_basedir

● 現(xiàn)在去php-fpm.d下的www.conf （www pool）定義open_basedir

[root@root-01 ~]# cd /usr/local/php-fpm/etc/php-fpm.d root@root-01 php-fpm.d]# vim www.conf [www] #listen = /tmp/php-fcgi.sock #listen = /tmp/php-fcgi.sock listen = 127.0.0.1:9000 listen.mode = 666 user = php-fpm group = php-fpm pm = dynamic pm.max_children = 50 pm.start_servers = 20 pm.min_spare_servers = 5 pm.max_spare_servers = 35 pm.max_requests = 500 rlimit_files = 1024 request_slowlog_timeout = 1 slowlog = /usr/local/php-fpm/var/log/www.slow.log 加入這行： php_admin_value[open_basedir]=/data/www/test.com:/tmp/

保存退出后，重啟一下php-fpm

使用curl來(lái)測(cè)試一下,狀態(tài)碼200

[root@root-01 php-fpm.d]# curl -x127.0.0.1:80 test.com/sleep.php -I HTTP/1.1 200 OK Server: nginx/1.12.1 Date: Wed, 16 Aug 2017 05:51:06 GMT Content-Type: text/html; charset=UTF-8 Connection: keep-alive X-Powered-By: PHP/5.6.30

● 在php.ini配置文件里面的display_errors = off 一般在線上使用都是off,這樣做事為了不能讓別人通過(guò)瀏覽器看到錯(cuò)誤信息。而錯(cuò)誤日志是定義在服務(wù)器的某個(gè)文件里

第1步：進(jìn)入php.ini，把display_errors設(shè)置為 off

第2步：log_errors設(shè)為On

第3步：在error_log = syslog下面添加日志路徑 error_log = /usr/local/php-fpm/var/log/php_errors.log

第4步：定義error_reporting（日志級(jí)別），搜索 Common Values:添加error_reportinr = E_ALL. 然后把error_reportinr = E_ALL & ~E_DEPRECATED & ~E_STRICT 使用;注釋掉.

● 現(xiàn)在去/usr/local/php-fpm/var/log/目錄下手動(dòng)創(chuàng)建php_errors.log文件，并且把權(quán)限設(shè)置為777,目的是為了能夠正常的寫(xiě)入內(nèi)容.

[root@root-01 ~]# cd /usr/local/php-fpm/var/log/ [root@root-01 log]# touch php_errors.log [root@root-01 log]# ls php_errors.log php-fpm.log www.slow.log [root@root-01 log]# chmod 777 php_errors.log

● 進(jìn)入www.conf，把定義open_basedir的路徑故意定義錯(cuò)

[root@root-01 php-fpm.d]# vim www.conf [www] #listen = /tmp/php-fcgi.sock listen = 127.0.0.1:9000 listen.mode = 666 user = php-fpm group = php-fpm pm = dynamic pm.max_children = 50 pm.start_servers = 20 pm.min_spare_servers = 5 pm.max_spare_servers = 35 pm.max_requests = 500 rlimit_files = 1024 request_slowlog_timeout = 1 slowlog = /usr/local/php-fpm/var/log/www.slow.log php_admin_value[open_basedir]=/data/www/Anna.com:/tmp/ -->原本是test.com,現(xiàn)在把更改為Anna.com

● 重啟php-fpm

[root@root-01 php-fpm.d]# /etc/init.d/php-fpm restart Gracefully shutting down php-fpm . done Starting php-fpm done

● 現(xiàn)在curl來(lái)測(cè)試訪問(wèn)，結(jié)果顯示404

[root@root-01 php-fpm.d]# curl -x127.0.0.1:80 test.com/sleep.php -I HTTP/1.1 404 Not Found Server: nginx/1.12.1 Date: Wed, 16 Aug 2017 06:29:23 GMT Content-Type: text/html; charset=UTF-8 Connection: keep-alive X-Powered-By: PHP/5.6.30

● 現(xiàn)在來(lái)查看一下錯(cuò)誤日志

[root@root-01 log]# cat php_errors.log [16-Aug-2017 06:29:23 UTC] PHP Warning: Unknown: open_basedir restriction in effect. File(/data/www/test.com/sleep.php) is not within the allowed path(s): (/data/www/Anna.com:/tmp/) in Unknown on line 0 [16-Aug-2017 06:29:23 UTC] PHP Warning: Unknown: failed to open stream: Operation not permitted in Unknown on line 0 說(shuō)明 open_basedir有限制，限制在（/data/www/Anna.com），而/data/www/test.com/sleep.php是位未知路徑.

● 把www.conf open——basedir路更改為正確的，在使用curl來(lái)訪問(wèn)就顯示200正常.

[root@root-01 php-fpm.d]# vim www.conf [www] #listen = /tmp/php-fcgi.sock listen = 127.0.0.1:9000 listen.mode = 666 user = php-fpm group = php-fpm pm = dynamic pm.max_children = 50 pm.start_servers = 20 pm.min_spare_servers = 5 pm.max_spare_servers = 35 pm.max_requests = 500 rlimit_files = 1024 request_slowlog_timeout = 1 slowlog = /usr/local/php-fpm/var/log/www.slow.log php_admin_value[open_basedir]=/data/www/test.com:/tmp/ [root@root-01 php-fpm.d]# /etc/init.d/php-fpm restart Gracefully shutting down php-fpm . done Starting php-fpm done [root@root-01 php-fpm.d]# curl -x127.0.0.1:80 test.com/sleep.php -I HTTP/1.1 200 OK Server: nginx/1.12.1 Date: Wed, 16 Aug 2017 06:43:32 GMT Content-Type: text/html; charset=UTF-8 Connection: keep-alive X-Powered-By: PHP/5.6.30 php-fpm進(jìn)程管理

www.conf 里面有以下配置：

pm = dynamic pm.max_children = 50 pm.start_servers = 20 pm.min_spare_servers = 5 pm.max_spare_servers = 35 pm.max_requests = 500 pm = dynamic 定義php-fpm的子進(jìn)程啟動(dòng)模式，dynamic為動(dòng)態(tài)模式；一開(kāi)始只是啟動(dòng)少量的子進(jìn)程，根據(jù)實(shí)際需要，動(dòng)態(tài)地增加或者減少子進(jìn)程，最多不會(huì)超過(guò)pm.max_children 定義的數(shù)值 pm.start_servers 針對(duì)dynamic模式，定義php-fpm服務(wù)在啟動(dòng)服務(wù)時(shí)產(chǎn)生的子進(jìn)程數(shù)量. pm.min_spare_servers 針對(duì)dynamic模式，定義在空閑時(shí)段子進(jìn)程數(shù)的最少數(shù)量，如果達(dá)到這個(gè)數(shù)量時(shí)，php-fpm會(huì)自動(dòng)生成新的子進(jìn)程. pm.max_spare_servers 針對(duì)dynamic模式,定義一個(gè)子進(jìn)程最多處理的請(qǐng)求數(shù)，也就是說(shuō)在一個(gè)pho-fpm的子進(jìn)程中最多可以處理這么請(qǐng)求，當(dāng)達(dá)到這個(gè)數(shù)值時(shí)，它會(huì)自動(dòng)退出. 還有一種模式是static(靜態(tài)的），如果把pm = dynamic更改為pm = static，那么只生效pm.max_children，一次性啟動(dòng)這么多，不會(huì)減少也不會(huì)增加其他的pm.start_servers；pm.min_spare_servers；pm.max_spare_servers；pm.max_requests 都不會(huì)再生效.

● 把www.conf更為static

[root@root-01 php-fpm.d]# vim www.conf [www] #listen = /tmp/php-fcgi.sock listen = 127.0.0.1:9000 listen.mode = 666 user = php-fpm group = php-fpm pm = dynamic #pm = static pm.max_children = 50 pm.start_servers = 20 pm.min_spare_servers = 5 pm.max_spare_servers = 35 pm.max_requests = 500 rlimit_files = 1024 request_slowlog_timeout = 1 slowlog = /usr/local/php-fpm/var/log/www.slow.log php_admin_value[open_basedir]=/data/www/test.com:/tmp/

●保存退出后，重啟php-fpm，再使用ps aux |grep php-fpm就可以看到一次性啟動(dòng)50個(gè)子進(jìn)程
