php-fpm的pool

● php-fpm的pool,在ps aux的时候在右侧可以看到那一列，php-fpm的pool,也就是php-fpm的池子.

●在php-fpm.conf里面定义了一个池子，支持定义多个池子，每个池子可以监听不同sock或tcp.例如Nginx有多个站点，每个站点都可以使用不同pool.如果Nginx有多个站点都使用一个pool的话，假如出现了502的，出现在502状态码，有可能是因为php资源不够，那么所有的站点都502，但是如果Nginx每个站点使用单独pool,其中一个站点502了，但不会影响到其他站点.

● 新增加一个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，检查一下语法是否有误,并重启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

● 重启php-fpm后ps aux |grep php-fpm，会发现多了Anna.com的pool

[root@root-01 ~]# ps aux |grep php-fpm root 2871 7.0 0.4 224400 4956 ? Ss 10:44 0:00 php-fpm: master process (/usr/local/php-fpm/etc/php-fpm.conf) php-fpm 2872 0.0 0.4 224340 4640 ?

● 现在有两个pool，在test.conf.com站点监听是127.0.0.1:9000，现在就把aaa.com.conf定义为Anna.com，这样的话这样两个站点就隔离开了.

[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; } } 说明 假如test.conf.com很忙，请求量很大，将php-fpm进程耗尽，最多可以启动50个进程，所有的进程都在忙，当再来一个新的请求的时候，就会出现了502，因为没有多余的php-fpm进程提供服务.但aaa.com.conf并不会受影响，因为使用的是另外一个pool，这就是建立多个pool的好处.

●在/usr/local/nginx/conf/nginx.conf里面定义了include vhost/.conf，在php-fpm.conf也是支持的，现在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/目录下面创建配置文件目录和子配置文件.

[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 里面的两个pool分别剪贴到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

● 检查语法是否有误&重启php-fpm，在ps aux |grep php-fpm查看是效果是一样的，只不过这样会更加清晰.

S 11:32 0:00 php-fpm: pool www root 3009 0.0 0.0 112664 964 pts/2 S+ 11:32 0:00 grep --color=auto php-fpm php-fpm慢执行日志

前言：php-fpm慢执行日志，在日常工作中使用的非常多，可以帮助我们快速追查到问题点.

● 做PHP网站，建议使用lnmp,其中有一个原因就是我们可以去分析PHP的慢执行日志，为什么要分析PHP的慢执行日志呢？在运维工作中，经常会遇到一个很让头痛的问题，公司老板或客户经常反馈公司网站访问慢.为什么会慢？运维人员要知道根本原因，要知道慢在哪个地方.PHP网站是有办法指定慢在哪里.

服务器负载高，我们可以使用free,top等命令去查看，可以知道到底是哪个进程导致负载高. 种种迹象表明php-fpm进程占用了很多资源，但是并不知道为什么php-fpm在做什么，那么有php慢执行日志我们就可以查看到问题点，所以php慢执行日志非常重要.

● 现在针对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 加入这行配置： request_slowlog_timeout = 1 --->请求慢日志超过1秒钟，就会记录日志 slowlog = /usr/local/php-fpm/var/log/www.slow.log --->定义日志路径

● 保存退出后，检查语法是否有误，并重新加载php-fpm,在查看/usr/local/php-fpm/var/log/目录下是否有生成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

●模拟一个慢执行的PHP，写一个脚本，www这个pool是test.com.conf站点在使用，所以要针对这个站点做操作. 在/data/www/test.com/目录下写一个sleep.php的脚本

[root@root-01 ~]# vim /data/www/test.com/sleep.php ~ 说明 这脚本是要在执行的停2秒，因为在配置www.conf文件请求慢日志超过1秒钟，就会记录日志.

● 使用curl来测试一下，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 说明 script_filename = /data/www/test.com/sleep.php ---> 这行是告诉我们执行慢慢在哪里. [0x00007f40307e52e8] sleep() /data/www/test.com/sleep.php:3 -->慢在具体哪一行. 说明 这就是php慢执行日志的好处. 12.23 open_basedir

前言：open_basedir的目的就是安全，

● php-fpm也是可以定义open_basedir，之前讲过在php.ini中去定义，如果服务器上有多个网站，在php.ini里面去定义就不合适了.要么在Apache虚拟主机里面配置，要么在php-fpm里面配置，我们可以根据不同的pool去定义open_basedir

● 现在去php-fpm.d下的www.conf （www pool）定义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 加入这行： php_admin_value[open_basedir]=/data/www/test.com:/tmp/

保存退出后，重启一下php-fpm

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

使用curl来测试一下,状态码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 一般在线上使用都是off,这样做事为了不能让别人通过浏览器看到错误信息。而错误日志是定义在服务器的某个文件里

第1步：进入php.ini，把display_errors设置为 off

第2步：log_errors设为On

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

第4步：定义error_reporting（日志级别），搜索 Common Values:添加error_reportinr = E_ALL. 然后把error_reportinr = E_ALL & ~E_DEPRECATED & ~E_STRICT 使用;注释掉.

● 现在去/usr/local/php-fpm/var/log/目录下手动创建php_errors.log文件，并且把权限设置为777,目的是为了能够正常的写入内容.

[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

● 进入www.conf，把定义open_basedir的路径故意定义错

[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,现在把更改为Anna.com

● 重启php-fpm

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

● 现在curl来测试访问，结果显示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

● 现在来查看一下错误日志

[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 说明 open_basedir有限制，限制在（/data/www/Anna.com），而/data/www/test.com/sleep.php是位未知路径.

● 把www.conf open——basedir路更改为正确的，在使用curl来访问就显示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进程管理

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 定义php-fpm的子进程启动模式，dynamic为动态模式；一开始只是启动少量的子进程，根据实际需要，动态地增加或者减少子进程，最多不会超过pm.max_children 定义的数值 pm.start_servers 针对dynamic模式，定义php-fpm服务在启动服务时产生的子进程数量. pm.min_spare_servers 针对dynamic模式，定义在空闲时段子进程数的最少数量，如果达到这个数量时，php-fpm会自动生成新的子进程. pm.max_spare_servers 针对dynamic模式,定义一个子进程最多处理的请求数，也就是说在一个pho-fpm的子进程中最多可以处理这么请求，当达到这个数值时，它会自动退出. 还有一种模式是static(静态的），如果把pm = dynamic更改为pm = static，那么只生效pm.max_children，一次性启动这么多，不会减少也不会增加其他的pm.start_servers；pm.min_spare_servers；pm.max_spare_servers；pm.max_requests 都不会再生效.

● 把www.conf更为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，重启php-fpm，再使用ps aux |grep php-fpm就可以看到一次性启动50个子进程
