一、php-fpm的pool；php

在php-fpm里面有一个概念,叫作pool,使用ps aux|grep php-fpm最右侧的那一列就是pool,也就是它的池子；html

[root@localhost_001 vhost]# ps aux |grep php-fpm
root       1072  0.0  0.2 227240  4948 ?        Ss   09:31   0:00 php-fpm: master process (/usr/local/php-fpm/etc/php-fpm.conf)
php-fpm    1073  0.0  0.2 227240  4704 ?        S    09:31   0:00 php-fpm: pool www
php-fpm    1074  0.0  0.2 227240  4704 ?        S    09:31   0:00 php-fpm: pool www
php-fpm    1075  0.0  0.2 227240  4704 ?        S    09:31   0:00 php-fpm: pool www
php-fpm    1076  0.0  0.2 227240  4704 ?        S    09:31   0:00 php-fpm: pool www
php-fpm    1077  0.0  0.2 227240  4708 ?        S    09:31   0:00 php-fpm: pool www
php-fpm    1078  0.0  0.2 227240  4708 ?        S    09:31   0:00 php-fpm: pool www
php-fpm    1079  0.0  0.2 227240  4708 ?        S    09:31   0:00 php-fpm: pool www
php-fpm    1080  0.0  0.2 227240  4708 ?        S    09:31   0:00 php-fpm: pool www
[root@localhost_001 vhost]# ps aux |grep php-fpm |grep -v 'grep'|wc -l
21

2:切换目录,会看到咱们只定义了一个www的pool；nginx

注释：实际上是支持定义多个池子的,每个池子能够监听不一样的sock和IP地址,nginx有多个站点的时候,每一个站点去使用一个独立的pool；apache

站点分开使用pool的优点：当其中一个php发生了502错误(有多是资源不够了),若是全部的站点共同使用了一个pool池子,那么当其中一个网站发生了故障(可能写的程序有问题),会把你的php的资源耗尽,这样会形成其余站点也会502,因此有必要把每一个站点隔离开来,每个站点使用独立的pool；   请求过多,资源耗尽；vim

设置多个pool的方法以下；浏览器

(1):在/usr/local/php-fpm/etc/php-fpm里继续增长第二个pool；   test    以下：安全

[root@localhost_001 etc]# cat 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

[test]                           #定义的第二个pool池子;
listen = /tmp/test.sock          #经过监听的sock来区分;
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

注释：如上图例:咱们自定义名称：test     自定义监听方式为 listen = /tmp/test.sockbash

3:而后检测php-fpm 并从新启动服务；服务器

[root@localhost_001 etc]# /usr/local/php-fpm/sbin/php-fpm -t
[06-Nov-2018 12:37:27] NOTICE: configuration file /usr/local/php-fpm/etc/php-fpm.conf test is successful

[root@localhost_001 etc]# service php-fpm restart
Gracefully shutting down php-fpm . done
Starting php-fpm  done

4:这是再使用ps aux|grep php-fpm 查看,会发现右侧多了 test 的 pool 的池子；curl

[root@localhost_001 etc]# ps aux |grep php-fpm
root       3750  0.0  0.2 123708  4968 ?        Ss   12:37   0:00 php-fpm: master process (/usr/local/php-fpm/etc/php-fpm.conf)
php-fpm    3751  0.0  0.2 123648  4700 ?        S    12:37   0:00 php-fpm: pool www
php-fpm    3752  0.0  0.2 123648  4700 ?        S    12:37   0:00 php-fpm: pool www
php-fpm    3753  0.0  0.2 123648  4700 ?        S    12:37   0:00 php-fpm: pool www
php-fpm    3754  0.0  0.2 123648  4700 ?        S    12:37   0:00 php-fpm: pool www
php-fpm    3755  0.0  0.2 123648  4704 ?        S    12:37   0:00 php-fpm: pool www
php-fpm    3787  0.0  0.2 123648  4712 ?        S    12:37   0:00 php-fpm: pool test
php-fpm    3788  0.0  0.2 123648  4712 ?        S    12:37   0:00 php-fpm: pool test
php-fpm    3789  0.0  0.2 123648  4716 ?        S    12:37   0:00 php-fpm: pool test
php-fpm    3790  0.0  0.2 123648  4716 ?        S    12:37   0:00 php-fpm: pool test
[root@localhost_001 etc]# ps aux |grep php-fpm|grep test|wc -l
20

注释：当时主进程仍是只有1个的；

5:在nginx配置里用另外一个站点使用新的pool池子；

[root@localhost_001 etc]# cd /usr/local/nginx/conf/vhost/
[root@localhost_001 vhost]# ls
aaa.com.conf  ssl.conf  test.com.conf

注释：如上图例,咱们有两个站点；  aaa.com    test.com.conf

1:test.com.conf使用是www的pool,经过以下配置来指定使用哪一个pool；

#fastcgi_pass  unix:/tmp/php-fcgi.sock;       #经过指定/tmp/下的通讯sock来决定使用哪一个pool池子；

[root@localhost_001 vhost]# cat test.com.conf 
server
{
    listen 80;
    server_name www.test.com bbs.test.com test1.com;
    index index.html index.htm index.php;
    root /data/wwwroot/test.com;
    location ~ \.php$
    {
        include fastcgi_params;
        fastcgi_pass unix:/tmp/php-fcgi.sock;   #指定使用php-fcgi的pool池子;##写错这个路径,就会显示502
    #    fastcgi_pass 127.0.0.1:9000; 
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME /data/wwwroot/test.com$fastcgi_script_name;
    }
    access_log /tmp/test.com.log combined_realip;
}

 

2:设置aaa.com来使用以前定义好的pool池子test；

[root@localhost_001 vhost]# vim aaa.com.conf  
server
{
    listen 80 default_server; 
    # 有这个标记的就是默认虚拟主机
    server_name aaa.com;
    index index.html index.htm index.php;
    root /data/wwwroot/default;
    location ~ \.php$
    {
        include fastcgi_params;
        fastcgi_pass unix:/tmp/test.sock;        #指定使用test的pool池子;##写错这个路径,就会显示502
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME /data/wwwroot/test.com$fastcgi_script_name;
    }
}

注释：如上图例,这样两个站点就隔离开了;

注释：假设www.test.com请求了很大,最终将php-fpm进程耗尽了,当有其余的请求过来时,就会报502错误,由于没有多余的php-fpm提供服务了,而另外一个站点aaa.com则不受影响,由于使用的是另外一个pool池子(test),这就是须要定义多个池子的缘由了；

6:方法二,在/usr/local/php-fpm/etc/php-fpm写入include  vhost/*.conf,而后vhost下分别写入多个pool池子,其他配置不变；

注释：这里的配置和nginx的虚拟主机的用法是同样子的；

1:首先把在配置文件/usr/local/php-fpm/etc/php-fpm里global里加入以下一行；将其余池子的内容都删除；  100dd  ---> 快速删除；

2:上图例中定义include定义的是在etc/php-fpm.d/*.conf目录下,全部还须要建立这个目录；

[root@localhost_001 etc]# mkdir php-fpm.d
[root@localhost_001 etc]# ls
pear.conf  php-fpm.conf  php-fpm.conf.default  php-fpm.d  php.ini

3:建立www.conf(即www.test.com的pool池子)；

[root@localhost_001 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

建立test.com(即aaa.com的pool池子)；

[root@localhost_001 php-fpm.d]# vim test.conf 
[test]                           #定义的第二个pool池子;
listen = /tmp/test.sock          #经过监听的sock来区分;
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

4:检测是否有错误,并从新启动php-fpm；

[root@localhost_001 php-fpm.d]# /usr/local/php-fpm/sbin/php-fpm -t
[06-Nov-2018 14:21:23] NOTICE: configuration file /usr/local/php-fpm/etc/php-fpm.conf test is successful
[root@localhost_001 php-fpm.d]# service php-fpm restart
Gracefully shutting down php-fpm . done
Starting php-fpm  done

5:用ps aux |grep php-fpm 查看是否正常；

[root@localhost_001 php-fpm.d]# ps aux |grep php-fpm
root       3888  0.0  0.2 123708  4976 ?        Ss   14:21   0:00 php-fpm: master process (/usr/local/php-fpm/etc/php-fpm.conf)
php-fpm    3889  0.0  0.2 123648  4704 ?        S    14:21   0:00 php-fpm: pool test
php-fpm    3890  0.0  0.2 123648  4704 ?        S    14:21   0:00 php-fpm: pool test
php-fpm    3891  0.0  0.2 123648  4704 ?        S    14:21   0:00 php-fpm: pool test
php-fpm    3892  0.0  0.2 123648  4704 ?        S    14:21   0:00 php-fpm: pool test
php-fpm    3893  0.0  0.2 123648  4708 ?        S    14:21   0:00 php-fpm: pool test
php-fpm    3894  0.0  0.2 123648  4708 ?        S    14:21   0:00 php-fpm: pool test
php-fpm    3921  0.0  0.2 123648  4716 ?        S    14:21   0:00 php-fpm: pool www
php-fpm    3922  0.0  0.2 123648  4716 ?        S    14:21   0:00 php-fpm: pool www
php-fpm    3923  0.0  0.2 123648  4716 ?        S    14:21   0:00 php-fpm: pool www
php-fpm    3924  0.0  0.2 123648  4716 ?        S    14:21   0:00 php-fpm: pool www
php-fpm    3925  0.0  0.2 123648  4716 ?        S    14:21   0:00 php-fpm: pool www
php-fpm    3926  0.0  0.2 123648  4716 ?        S    14:21   0:00 php-fpm: pool www
php-fpm    3927  0.0  0.2 123648  4720 ?        S    14:21   0:00 php-fpm: pool www
php-fpm    3928  0.0  0.2 123648  4720 ?        S    14:21   0:00 php-fpm: pool www

三、php的慢执行日记；

在作php的网站,建议使用lnmp,方便分析php的慢执行日记；

查询方法：系统负载,能够经过各类工具查看,查出是那个进程致使的；

php的访问慢：经过查看慢执行日记；

1:在php的pool池子中添加以下两行；   /usr/local/php-fpm/etc/php-fpm.d/www.conf

[root@localhost_001 php-fpm.d]# vim /usr/local/php-fpm/etc/php-fpm.d/www.conf 
[root@localhost_001 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
3新赠以下两行;
request_slowlog_timeout = 1     #慢执行超过1s后则记录日记;
slowlog = /usr/local/php-fpm/var/log/www-slow.log      #慢执行日记记录的位置在这里;

2:检测语法错误并从新加载配置文件；

[root@localhost_001 php-fpm.d]# /usr/local/php-fpm/sbin/php-fpm -t
[06-Nov-2018 14:36:27] NOTICE: configuration file /usr/local/php-fpm/etc/php-fpm.conf test is successful
[root@localhost_001 php-fpm.d]# service php-fpm restart
Gracefully shutting down php-fpm . done
Starting php-fpm  done

3:查看慢执行日记文件是否生成；

[root@localhost_001 php-fpm.d]# ls /usr/local/php-fpm/var/log/www-slow.log 
/usr/local/php-fpm/var/log/www-slow.log
[root@localhost_001 php-fpm.d]# cat /usr/local/php-fpm/var/log/www-slow.log

注释：日记为空,由于没有慢执行的记录；

4:此时模拟慢执行的php,因此须要在/data/wwwroot/test下操做；

[root@localhost_001 php-fpm.d]# vim /data/wwwroot/test.com/sleep.php
cat /data/wwwroot/test.com/sleep.php
<?php
echo “test slow log”;
sleep(2);echo “done”;
?>

运行php脚本；未输出任何信息,状态码限制500错误；

[root@localhost_001 php-fpm.d]# curl -x127.0.0.1:80 www.test.com/sleep.php -I
HTTP/1.1 500 Internal Server Error
Server: nginx/1.4.7
Date: Tue, 06 Nov 2018 06:42:01 GMT
Content-Type: text/html; charset=UTF-8
Connection: keep-alive
X-Powered-By: PHP/5.6.30

5:查看错误日记,简单的方法是在它的配置里打开错误日记显示,让其显示到浏览器上；

[root@localhost_001 php-fpm.d]# vim /usr/local/php-fpm/etc/php.ini
display_errors = On

[root@localhost_001 php-fpm.d]# service php-fpm start

再次用curl命令来查看；  显示语法错误；有多是逗号    分号写的不对；

[root@localhost_001 php-fpm.d]# curl -x127.0.0.1:80 www.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 />

再次查看其sleep.php    修改其标点符号；

[root@localhost_001 php-fpm.d]# vim /data/wwwroot/test.com/sleep.php 
<?php
echo "test slow log";
sleep(2);echo "done";
?>
[root@localhost_001 php-fpm.d]# service php-fpm restart
Gracefully shutting down php-fpm . done
Starting php-fpm  done

5:再次测试,会看到访问成功了,可是停顿了几秒；

[root@localhost_001 php-fpm.d]# !curl
curl -x127.0.0.1:80 www.test.com/sleep.php

6:再次查看是否生成了慢查询日记；

[root@localhost_001 php-fpm.d]# cat /usr/local/php-fpm/var/log/www-slow.log 

[06-Nov-2018 14:53:00]  [pool www] pid 4168
script_filename = /data/wwwroot/test.com/sleep.php
[0x00007fbc55df1258] sleep() /data/wwwroot/test.com/sleep.php:3

注释：这个是慢查询日记的功能了,若是遇到php访问慢的状况,能够经过此日记来查看；

注释：在/usr/local/php-fpm/etc/php-fpm.d/www.conf里定义的内容：request_slowlog_timeout = 1   #后面的1设置慢执行日记的时间；

注释：通常都设置为2s,php的执行时间介于1到2秒之间；

三、php-fpm定义open_basedir：

做用：是限制php在指定的目录内活动；也为了安全；

由于服务器管理多个网站,在php.ini里定义多个open_basedir就不合适了,因此要么在apache的虚拟主机里定义,要么在php-fpm配置文件里定义,咱们能够针对不一样的池子去定义不一样的open_basedir；

1:针对www.conf(pool池子为www来设置)：

[root@localhost_001 php-fpm.d]# vim /usr/local/php-fpm/etc/php-fpm.d/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/

2:检测并重启php-fpm；

[root@localhost_001 php-fpm.d]# /usr/local/php-fpm/sbin/php-fpm -t
[06-Nov-2018 15:03:36] NOTICE: configuration file /usr/local/php-fpm/etc/php-fpm.conf test is successful
[root@localhost_001 php-fpm.d]# service php-fpm restart
Gracefully shutting down php-fpm . done
Starting php-fpm  done

3:访问测试；  curl   -x127.0.0.1:80    www.test.com/2.php

[root@localhost_001 php-fpm.d]# curl -x127.0.0.1:80 www.test.com/2.php -I
HTTP/1.1 200 OK
Server: nginx/1.4.7
Date: Tue, 06 Nov 2018 07:04:47 GMT
Content-Type: text/html; charset=UTF-8
Connection: keep-alive
X-Powered-By: PHP/5.6.30

注释：若open_basedir路径定义错误,就会致使没法访问,造成404的状态码,curl命令会显示 “no  input   file   specified”

[root@localhost_001 php-fpm.d]# vim www.conf 
[www]                    
listen = /tmp/php-fcgi.sock 
........      
php_admin_value[open_basedir]=/data/wwwroot/default:/tmp/
[root@localhost_001 php-fpm.d]# service php-fpm restart     #从新启动php-fpm服务;
Gracefully shutting down php-fpm . done
Starting php-fpm  done
[root@localhost_001 php-fpm.d]# curl -x127.0.0.1:80 www.test.com/2.php 
No input file specified.
[root@localhost_001 php-fpm.d]# curl -x127.0.0.1:80 www.test.com/2.php -I
HTTP/1.1 404 Not Found
Server: nginx/1.4.7
Date: Tue, 06 Nov 2018 07:18:48 GMT
Content-Type: text/html; charset=UTF-8
Connection: keep-alive
X-Powered-By: PHP/5.6.30

4:定义错误日记；    /usr/local/php-fpm/etc/php.ini

[root@localhost_001 etc]# vim php.ini
;搜索display_errors 并设置为 Off,不让错误日记输出到浏览器上,不安全;
display_errors = Off                
;error_log = syslog
;定义错误日记存放路径;
error_log = /usr/local/php/var/log/php_error.log
;定义错误日记的级别;  error_reporting = E_ALL   
;error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT
error_reporting = E_ALL          #定义错误日记级别;

注释：display_errors = Off  这个在线上是关闭的,不能让别人经过你的浏览器信息看看php的错误,而是要把错误记录到某个文件里；

检测并从新加载php-fpm的服务；

[root@localhost_001 etc]# /usr/local/php-fpm/sbin/php-fpm -t
[06-Nov-2018 15:33:46] NOTICE: configuration file /usr/local/php-fpm/etc/php-fpm.conf test is successful

[root@localhost_001 etc]# service php-fpm restart
Gracefully shutting down php-fpm . done
Starting php-fpm  done

5:手动建立php_error.log错误日记,并设置777,防止不能写入；

[root@localhost_001 etc]# touch /usr/local/php-fpm/var/log/php_error.log
[root@localhost_001 etc]# chmod 777 !$
chmod 777 /usr/local/php-fpm/var/log/php_error.log
[root@localhost_001 etc]# ls -ld !$
ls -ld /usr/local/php-fpm/var/log/php_error.log
-rwxrwxrwx 1 root root 256 11月  6 15:35 /usr/local/php-fpm/var/log/php_error.log

6:而后测试；再次用 curl 命令来访问；

[root@localhost_001 etc]# curl -x127.0.0.1:80 www.test.com/2.php 
No input file specified.
[root@localhost_001 etc]# curl -x127.0.0.1:80 www.test.com/2.php -I
HTTP/1.1 404 Not Found

Content-Type: text/html; charset=UTF-8
Connection: keep-alive
X-Powered-By: PHP/5.6.30

7:查看错误日记信息；      /usr/local/php-fpm/var/log/php_error.log

[root@localhost_001 etc]# tail /usr/local/php-fpm/var/log/php_error.log

[06-Nov-2018 07:36:41 UTC] PHP Warning:  Unknown: failed to open stream: Operation not permitted in Unknown on line 0

8:而后修改open_basedir到原先的test.com目录,而后再次访问；

[root@localhost_001 php-fpm.d]# cat www.conf 
[www]                    
listen = /tmp/php-fcgi.sock        
........
php_admin_value[open_basedir]=/data/wwwroot/test.com:/tmp/
[root@localhost_001 php-fpm.d]# service php-fpm restart      #从新启动php-fpm服务;
Gracefully shutting down php-fpm . done
Starting php-fpm  done

9:而后再次用curl命令来访问；    curl   -x127.0.0.1:80    www.test.com/2.php  -I

</div></body></html>[root@localhost_001 php-fpm.d]# curl -x127.0.0.1:80 www.test.com/2.php -I
HTTP/1.1 200 OK

四、php-fpm进程管理；    配置介绍；；；

[root@localhost_001 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/

pm = dynamic        表示进程以什么形式启动( dynamic| static ),dynamic就是动态启动,动态就是一开始是一个数值,会根据需求来自动生成,服务器比较闲的时候还会去销毁,销毁到必定程度时还会去自动生成；

pm.max_children = 50   表示最大子进程数；(当设置成static后,则只有这一行会生效,下面的都不生效,会一次性生成50个子进程) 

pm.start_servers = 20                  启动服务时会启动的进程数； ps   aux  |grep  php-fpm

pm.min_spare_servers = 5          定义空闲时段,子进程的最少数量,若是未达到,php-fpm会派生新的子进程；

pm.max_spare_servers = 35       定义空闲时段,子进程的最大值,若是高于这个值就开始清理空闲的子进程；

pm.max_requests = 500             每一个子进程最多处理的请求数,也就是一个php-fpm的子进程最多处理这么多请求,当达到这个数值后,它就自动退出；

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/

注释：dynamic和static   表示以什么形式启动(动态或静态)；

pm = dynamic 就是动态,动态就是一开始为一个数值,而后根据须要再自动生成,服务器比较闲的时候还会去销毁,销毁到必定程度还会自动建立,会根据下面的设置来设定生效；

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/

而若当设置为 pm = static 后,则只有 pm.max_children = 50 这一个选项是生效的,其余都未生效；

pm.max_children = 50

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/
