一、php-fpm的pool
二、php-fpm慢执行日志
三、open_basedir
四、php-fpm进程管理
一、php-fpm的pool
和LAMP不同的是,在LNMP架构中,php-fpm作为独立的一个服务存在。
php-fpm的配置文件为/usr/local/php-fpm/etc/php-fpm.conf,它同样也支持
include语句,类似于nginx.conf里面的include。
Nignx可以配置多个虚拟主机,php-fpm同样也支持配置多个pool,每一个pool可以监听一个端口,也可以监听一个socket。

可以看到php-fpm已经有www和ming两个pool了。这样就可以在Nginx不同的虚拟主机中调用不同的pool,从而达到相互隔离的目的,两个pool互不影响。
- 指定虚拟主机中调用不同的pool
[root@minglinux-01 /usr/local/php-fpm/etc] cd /usr/local/nginx/conf/vhost/
[root@minglinux-01 /usr/local/nginx/conf/vhost] ls

···
50 location ~ \.php$
51 {
52 include fastcgi_params;
53 fastcgi_pass unix:/tmp/php-fcgi.sock; //这里监听的是www的socket地址
54 fastcgi_index index.php;
55 fastcgi_param SCRIPT_FILENAME /data/wwwroot/test.com$fastcgi_script_name;
56 }
···

nginx有多个站点,若只有一个php的pool,当某个站点或某些站点将pool的资源耗尽,就会导致其他使用该pool的站点出现502错误。如果每个站点使用各自独立的pool就不会有这种问题。
- php-fpm配置多个pool的另一种方式

二、php-fpm慢执行日志
php的网站,建议使用LNMP,当php网站运行慢时php-fpm的慢执行日志可以帮助快速地追踪到问题点。
- 开启和查看php-fpm的慢执行日志
[root@minglinux-01 /usr/local/php-fpm/etc/php-fpm.d] vim www.conf
//再最后面增加如下两行内容
1 [www]
2 listen = /tmp/php-fcgi.sock
3 listen.mode = 666
4 user = php-fpm
5 group = php-fpm
6 pm = dynamic
7 pm.max_children = 50
8 pm.start_servers = 20
9 pm.min_spare_servers = 5
10 pm.max_spare_servers = 35
11 pm.max_requests = 500
12 rlimit_files = 1024
13 request_slowlog_timeout = 1
14 slowlog = /usr/local/php-fpm/var/log/www-slow.log
第一行定义超时时间,即PHP的脚本执行时间只要超过1秒就会记录日志,第二行定义慢执行日志的路径和名字。以后遇到PHP网站访问卡顿的问题时,要记得去查看这个慢执行日志。
- 测试
[root@minglinux-01 /usr/local/php-fpm/etc/php-fpm.d] /usr/local/php-fpm/sbin/php-fpm -t
[03-Dec-2018 22:01:46] NOTICE: configuration file /usr/local/php-fpm/etc/php-fpm.conf test is successful

···
50 location ~ \.php$
51 {
52 include fastcgi_params;
53 fastcgi_pass unix:/tmp/php-fcgi.sock; //监听的是www的socket地址
54 fastcgi_index index.php;
55 fastcgi_param SCRIPT_FILENAME /data/wwwroot/test.com$fastcgi_script_name;
56 }
···
[root@minglinux-01 /usr/local/php-fpm/etc/php-fpm.d] vim /data/wwwroot/test.com/sleep.php
//创建测试脚本如下
1
[root@minglinux-01 /usr/local/php-fpm/etc/php-fpm.d] curl -x127.0.0.1:80 test.com/sleep.php //测试
test slow log
done
[root@minglinux-01 /usr/local/php-fpm/etc/php-fpm.d] cat /usr/local/php-fpm/var/log/www-slow.log
[03-Dec-2018 22:15:34] [pool www] pid 5482
script_filename = /data/wwwroot/test.com/sleep.php
[0x00007fde0e9d8298] sleep() /data/wwwroot/test.com/sleep.php:3 //具体到行
通过php-fpm的慢执行日志可以非常清晰地了解到PHP的脚本哪里执行时间长,它可以定位到具体的行。
三、open_basedir
当服务器上有多个网站时,不适合在php.ini文件中定义openbasedir,可以在虚拟主机配置文件中定义或在php-fpm中定义
httpd可以针对每个虚拟主机设置一个open_basedir,php-fpm同样也可以针对不同的pool设置不同的open_basedir。
[root@minglinux-01 /usr/local/php-fpm/etc/php-fpm.d] vim www.conf
1 [www]
2 listen = /tmp/php-fcgi.sock
3 listen.mode = 666
4 user = php-fpm
5 group = php-fpm
6 pm = dynamic
7 pm.max_children = 50
8 pm.start_servers = 20
9 pm.min_spare_servers = 5
10 pm.max_spare_servers = 35
11 pm.max_requests = 500
12 rlimit_files = 1024
13 request_slowlog_timeout = 1
14 slowlog = /usr/local/php-fpm/var/log/www-slow.log
15 php_admin_value[open_basedir]=/data/wwwroot/test.com:/tmp/ //openbasedir路径定义不正确会无法访问

3.php文件在test.com路径下,而open_basedir路径限制在ming.com路径下,因此访问受限。将路径改正后即可访问成功。
四、php-fpm进程管理
[root@minglinux-01 /usr/local/php-fpm/etc/php-fpm.d] cat www.conf
···
pm = dynamic
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500
···
配置含义:
pm = dynamic定义php-fpm的子进程启动模式,dynamic为动态模式;一开始只启动少量的子进程,根据实际需求,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。另外一种模式为static,这种模式下子进程数量由pm.max_children决定,一次性启动这么多,不会减少也不会增加。
pm.start_servers针对dynamic模式,它定义php-fpm服务在启动服务时产生的子进程数量。后期再根据访问量增加,如果服务器较空闲时也会自动销毁进程。
pm.min_spare_servers针对dynamic模式,它定义在空闲时段子进程数的最少数量。若php-fpm进程空闲就会销毁部分进程,但至少会保留5个子进程。
pm.max_spare_servers也是针对dynamic模式的,它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针对dynamic模式,它定义一个子进程最多处理的请求数,也就是说在一个php-fpm的子进程中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,再派生另外的子进程处理后续请求。
- 修改配置文件
