重新配置配置文件，重新添加一个pool pool ，名字叫aaa.com
nginx有多个pool

现在怎么去用它们呢
为什么要定义多个 pool，加入test.com 请求很大，最终把进程耗尽了php-fpm ，最多启动50个，结果启动完50个所有的都在忙，又有新的请求的时候，结果就报502错误，因为他没有多余的php 进程给它提供服务，而这个站点不受影响，因为他用的是另一个 pool，这就是为什么要定义多个 pool的原因。

在主配置文件里面加入 include = etc/php-fpm.d/*.conf 加入到[global]里面，然后再把[www]和[global]分别拆出来

然后再把这些删掉,100dd 就是删除下面100行，实际只有27行

因为是include = etc/php-fpm.d/*.conf 所以要创建一个php-fpm.d的目录
然后再创建一个php-fpm.d的目录再去目录里面创建 www.conf aaa.com.conf

[[email protected] etc]# mkdir php-fpm.d

再检查配置文件重启下

以上就是多个pool的配置

12.22 php-fpm慢执行日志

如果做PHP得网站，建议使用LNMP，其中有一个原因在于我们可以去分析php的慢执行日志，为什么要分析它的慢执行日志呢，运维工作中，经常会遇到一个问题
老板会经常反馈，你们公司的网站访问慢了，或者客户说网站慢了，要知道根本原因，要知道慢在什么地方，java网站先不说，php的网站有是办法查到底慢在哪里，就像系统负载高可以用工具去分析，vmstat top 等等，可以找到哪个进程导致的，php网站慢，到底什么地方慢，所以这个慢日志，非常重要，
针对www做一个实验

[[email protected] php-fpm.d]# vim www.conf

[www]
listen = /tmp/php-fcgi.sock
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       //超过1秒钟 我就要记录日志
slowlog = /usr/local/php-fpm/var/log/www-slow.log   //日志放在这个目录下

~

:wq

[[email protected] php-fpm.d]# vim www.conf
[[email protected] php-fpm.d]# /usr/local/php-fpm/sbin/php-fpm -t

[[email protected] php-fpm.d]# /etc/init.d/php-fpm reload

[[email protected] php-fpm.d]#

先看下日志有没有生成有的 www-slow.log

[www]
listen = /tmp/php-fcgi.sock
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

[[email protected] php-fpm.d]# ls /usr/local/php-fpm/var/log/
php-fpm.log  www-slow.log
[[email protected] php-fpm.d]# 

[[email protected] php-fpm.d]# ls /usr/local/php-fpm/var/log/www-slow.log
/usr/local/php-fpm/var/log/www-slow.log
[[email protected] php-fpm.d]# cat !$
cat /usr/local/php-fpm/var/log/www-slow.log
[[email protected] php-fpm.d]#

看看它有没有内容呢，空的，因为你还没有任何的超过1秒的 php执行的过程
接下来需要模拟一个慢执行的php
来写一个脚本
php-fcgi 它是被这个（/usr/local/nginx/conf/vhost/test.com.conf
） test.com.conf站点用着 fastcgi_pass unix:/tmp/php-fcgi.sock;
所以你要去这个站点做一些操作了，在这个目录下/data/wwwroot/test.com

[[email protected] php-fpm.d]# vim /data/wwwroot/test.com/sleep.php

<?php
 echo “test slow log”;
sleep(2);
echo “done”;
?>

:wq

来测试下

[[email protected] php-fpm.d]# curl -x127.0.0.1:80 test.com/sleep.php -I
HTTP/1.1 200 OK
Server: nginx/1.12.1

[[email protected] php-fpm.d]#

出错误了，排查错误看日志，也有个简单的方法，直接打开它的配置文件,搜索display_error 把display_errors = On
可以直接查看到具体的错误是什么

[[email protected] php-fpm.d]# vim /usr/local/php-fpm/etc/php.ini

; development version only in development environments, as errors shown to
; application users can inadvertently leak otherwise secure information.

; This is php.ini-development INI file.

;;;;;;;;;;;;;;;;;;;

;;;;;;;;;;;;;;;;;;;

; http://php.net/display-errors
display_errors = On

[[email protected] php-fpm.d]# vim /usr/local/php-fpm/etc/php.ini
[[email protected] php-fpm.d]# /etc/init.d/php-fpm reload
Reload service php-fpm  done
[[email protected] php-fpm.d]# curl -x127.0.0.1:80 test.com/sleep.php
<br />
<b>Parse error</b>:  syntax error, unexpected ‘slow‘ (T_STRING), expecting ‘,‘ or ‘;‘ in <b>/data/wwwroot/test.com/sleep.php</b> on line <b>2</b><br />
[[email protected] php-fpm.d]#

提示语法错误，分号不对，双引号不对，进去改下

[[email protected] php-fpm.d]# vim /data/wwwroot/test.com/sleep.php

<?php
 echo "test slow log";
sleep(2);
echo "done";
?>

:wq

再来测试下,它会告诉你是这个脚本慢，脚本的第三行慢 /data/wwwroot/test.com/sleep.php:3

[[email protected] php-fpm.d]# vim /data/wwwroot/test.com/sleep.php
[[email protected] php-fpm.d]# curl -x127.0.0.1:80 test.com/sleep.php
test slow logdone
[[email protected] php-fpm.d]# cat /usr/local/php-fpm/var/log/www-slow.log 

[30 Jan 2018 00:29:29]  [pool www] pid 6123
script_filename = /data/wwwroot/test.com/sleep.php
[0x00007f06da03d298] sleep() /data/wwwroot/test.com/sleep.php:3
[[email protected] php-fpm.d]#

看下第三行 sleep(2); 是这一行，因为它执行了2秒钟，只要超过了1秒就会被记录慢日志，这就是慢日志的功效了

[[email protected] php-fpm.d]# cat /data/wwwroot/test.com/sleep.php
<?php
 echo "test slow log";
sleep(2);
echo "done";
?>

[[email protected] php-fpm.d]#

这样就可以生成慢日志

12.23 open_basedir

open_bassdir 之前也介绍了，在php-fpm 也可以定义的，如果你服务器上有多个网站，去php.ini就不合适了，所以要么去apache虚拟主机配置文件里定义，要么去php-fpm配置文件里去定义，可以针对每个 pool做不同的定义
比如我在www里面去定义

[[email protected] php-fpm.d]# vim www.conf

[www]
listen = /tmp/php-fcgi.sock
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/wwwroot/aaa.com:/tmp/
~     

:wq

[[email protected] php-fpm.d]# cat www.conf
[www]
listen = /tmp/php-fcgi.sock
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/wwwroot/aaa.com:/tmp/
[[email protected] php-fpm.d]#

正常的话/tmp/php-fcgi.sock 是test.com，定义成aaa.com 的话，去请求去访问php，肯定会出问题

404肯定就不对了，所以说是有问题的


[[email protected] php-fpm.d]# cat www.conf
[www]
listen = /tmp/php-fcgi.sock
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

slowlog = /usr/local/php-fpm/var/log/www-slow.log
php_admin_value[open_basedir]=/data/wwwroot/aaa.com:/tmp/
[[email protected] php-fpm.d]#

现在我们再去定义一个php

[[email protected] php-fpm.d]# vim /usr/local/nginx/conf/vhost/test.com.conf
[[email protected] php-fpm.d]# vim /data/wwwroot/test.com/
1.gif       2.js        3.php       admin/      index.html  sleep.php   upload/

修改下www.conf，你针对的地方是test.com 如果这个地方不去定义正确的路径，他就没办法去访问

[[email protected] php-fpm.d]# vim www.conf

[www]
listen = /tmp/php-fcgi.sock
listen.mode = 666

查看下错误日志

[[email protected] php-fpm.d]# vim /usr/local/php-fpm/etc/php.ini

来访问下

[[email protected] php-fpm.d]#

看下日志里有没有信息, 很明显地址 open_basedir restriction in effect 有限制
. File(/data/wwwroot/test.com/3.php) is not within the allowed path(s): (/data/wwwroot/wwtest.com:/tmp/)
很明显这俩个地址不同，所以就会报错，就会有问题

[[email protected] php-fpm.d]# cat /usr/local/php-fpm/var/log/php_errors.log
[29 Jan 2018 17:42:53 UTC] PHP Warning:  Unknown: open_basedir restriction in effect. File(/data/wwwroot/test.com/3.php) is not within the allowed path(s): (/data/wwwroot/wwtest.com:/tmp/) in Unknown on line 0

我们把它改正

现在可以了，这次就正常了，这就是openbasedir怎么去定义

12.24 php-fpm进程管理

[[email protected] php-fpm.d]# cat www.conf
[www]
listen = /tmp/php-fcgi.sock
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/wwwroot/test.com:/tmp/
[[email protected] php-fpm.d]#

pm = dynamic 表示以什么样的形式进程启动，用dynamic 动态，后面参数才会生效，
如果是静态，只有一行生效 pm.max_children = 50 其他后面的参数不会生效
pm = dynamic //动态进程管理，
也可以是static（静态）也就是我一下子记生成这么多
pm.max_children = 50 //最大子进程数，ps aux可以查看
pm.start_servers = 20 //启动服务时会启动的进程数
pm.min_spare_servers = 5 //定义在空闲时段，子进程数的最少数量，如果达到这个数值时，php-fpm服务会自动派生新的子进程。
pm.max_spare_servers = 35 //定义在空闲时段，子进程数的最大值，如果高于这个数值就开始清理空闲的子进程。
pm.max_requests = 500 //定义一个子进程最多处理的请求数，也就是说在一个php-fpm的子进程最多可以处理这么多请求，当达到这个数值时，它会自动退出。
