1.php-fpm有一个概念,叫做pool。 使用ps aux |grep php-fpm最右侧看到的那一列就是pool,也就是它的池子
[root@tianqi-01 vhost]# ps aux |grep php-fpm
root 1056 0.0 0.4 227204 4952 ? Ss 08:39 0:01 php-fpm: master process (/usr/local/php-fpm/etc/php-fpm.conf)

[root@tianqi-01 vhost]#
2.切换目录,会看到我们只定义了一个www的pool
[root@tianqi-01 vhost]# cd /usr/local/php-fpm/etc/
[root@tianqi-01 etc]# ls
pear.conf php-fpm.conf php-fpm.conf.default php.ini
[root@tianqi-01 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] //这里只定义了一个www的pool
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@tianqi-01 etc]#
3.其实是支持定义多个池子的,每一个池子都可以监听不同的sock或者TCP/IP,nginx如果有多个站点,那么每个站点都能去使用一个独立的pool。这样做的优势就是,当其中一个php发生502了(502很有可能是php资源不够了),如果所有的网站使用了同一个池子,那其中一个网站发生了故障(比如写的程序有问题),那么就会把你的php资源耗尽,这样就会造成其他的站点也会502,所以有必要把每一个站点隔离开来,每一个站点使用独立的pool。
4.设置多个pool
方法一
在/usr/local/php-fpm/etc/php-fpm里面,继续增加pool
写第二个pool,名称为tianqi.com,listen = /tmp/tianqi.sock
配置中的其他信息可根据自己的需求来配置
[root@tianqi-01 etc]# vim !$
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
[tianqi.com]
listen = /tmp/tianqi.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
5.检查是否存在语法错误
[root@tianqi-01 etc]# /usr/local/php-fpm/sbin/php-fpm -t
[16-Mar-2018 21:58:38] NOTICE: configuration file /usr/local/php-fpm/etc/php-fpm.conf test is successful
[root@tianqi-01 etc]#
6.若没有语法错误,做一个php-fpm重启
/etc/init.d/php-fpm restart 或使用 /etc/init.d/php-fpm reload
[root@tianqi-01 etc]# /etc/init.d/php-fpm reload
Reload service php-fpm done
[root@tianqi-01 etc]#
7.这里再来ps查看,会看到最右侧多了一个tianqi.com,这个就是两个不同的池子
[root@tianqi-01 etc]# ps aux |grep php-fpm

root 5447 0.0 0.0 112660 984 pts/0 R+ 22:02 0:00 grep --color=auto php-fpm
[root@tianqi-01 etc]#
8.在nginx中使用新的pool
[root@tianqi-01 conf]# cd /usr/local/nginx/conf/vhost
[root@tianqi-01 vhost]# ls
aaa.com.conf load.conf proxy.conf ssl.conf test.com.conf
[root@tianqi-01 vhost]#
9.可以把test.com.conf定义成fastcgi_pass unix:/tmp/php-fcgi.sock;
这是www池子中的php-fcgi.sock
[root@tianqi-01 vhost]# vim test.com.conf
server
{
listen 80;
server_name test.com test2.com test3.com;
index index.html index.htm index.php;
root /data/wwwroot/test.com;
if ($host != 'test.com' ) {
rewrite ^/(.*)$ http://test.com/$1 permanent;
}
# location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
# {
# expires 7d;
# access_log off;
# }
location ~* ^.+\.(gif|jpg|png|swf|flv|rar|zip|doc|pdf|gz|bz2|jpeg|bmp|xls)$
{
expires 7d;
valid_referers none blocked server_names *.test.com ;
if ($invalid_referer) {
return 403;
}
access_log off;
}
location ~ .*\.(js|css)$
{
# expires 12h;
access_log off;
}
location /admin/
{
allow 127.0.0.1;
allow 192.168.11.136;
deny all;
}
location ~ .*(upload|image)/.*\.php$
{
deny all;
}
if ($http_user_agent ~* 'Spider/3.0|YoudaoBot|Tomato')
{
return 403;
}
location ~ \.php$
{
include fastcgi_params;
fastcgi_pass unix:/tmp/php-fcgi.sock;
#fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /data/wwwroot/test.com$fastcgi_script_name;
}
access_log /tmp/test.com.log combined_realip;
}
10.再把另一个aaa.com.conf中 fastcgi_pass unix:/tmp/tianqi.sock;
这是tianqi.com池子中的tianqi.sock
路径/data/wwwroot/default$fastcgi_script_name;
[root@tianqi-01 vhost]# vim aaa.com.conf
server
{
listen 80 default_server;
server_name aaa.com;
index index.html index.htm index.php;
root /data/wwwroot/default;
location ~ \.php$
{
include fastcgi_params;
fastcgi_pass unix:/tmp/tianqi.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /data/wwwroot/default$fastcgi_script_name;
}
}
保存退出
11.这样这两个站点就隔离开了
12.假设现在test.com请求量很大,最终将进程耗尽了,比如php-fpm耗尽了,这时候又有其他请求来了,就会报502,因为没有多余的php给进程提供服务了,而另一个站点则不受影响,因为使用的是另一个池子,另一个pool,这就是定义多个池子的原因
方法二
1.在vhost目录下是多个.conf文件,在nginx.conf里面加了一条 include vhost/*.conf;
[root@tianqi-01 vhost]# ls
aaa.com.conf load.conf proxy.conf ssl.conf test.com.conf
[root@tianqi-01 vhost]# tail ../nginx.conf
tcp_nodelay on;
gzip on;
gzip_min_length 1k;
gzip_buffers 4 8k;
gzip_comp_level 5;
gzip_http_version 1.1;
gzip_types text/plain application/x-javascript text/css text/htm
application/xml;
include vhost/*.conf;
}
[root@tianqi-01 vhost]#
2.在php-fpm同样是支持 include vhost/*.conf;
3.在主配置文件php-fpm中的 [global] 加入include = etc/php-fpm.d/*.conf ,并将池子拆分出来,将其中的池子pool删除
快速删除内容方法,100dd就会给删除
[root@tianqi-01 vhost]# cd /usr/local/php-fpm/etc/
[root@tianqi-01 etc]# ls
pear.conf php-fpm.conf php-fpm.conf.default php.ini
[root@tianqi-01 etc]# vim php-fpm.conf
[global]
pid = /usr/local/php-fpm/var/run/php-fpm.pid
error_log = /usr/local/php-fpm/var/log/php-fpm.log
include = etc/php-fpm.d/*.conf //添加一条语句,删除下面的语句
保存退出
4.因为include = etc/php-fpm.d/,所以需要创建/php-fpm.d/的目录
[root@tianqi-01 etc]# mkdir php-fpm.d
[root@tianqi-01 etc]#
5.切换路径,并创建www.conf,然后将之前php-fpm.conf中的www部分写入到其中
[root@tianqi-01 etc]# cd !$
cd php-fpm.d
[root@tianqi-01 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
保存退出
6.然后再创建tianqi.conf
[root@tianqi-01 php-fpm.d]# vim tianqi.conf
[tianqi.com]
listen = /tmp/tianqi.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
7.这样看着就会很干净,类似于nginx的vhost
8.检查是否有错误
[root@tianqi-01 php-fpm.d]# /usr/local/php-fpm/sbin/php-fpm -t
[16-Mar-2018 22:24:33] NOTICE: configuration file /usr/local/php-fpm/etc/php-fpm.conf test is successful
[root@tianqi-01 php-fpm.d]#
9.然后重启查看
[root@tianqi-01 php-fpm.d]# /etc/init.d/php-fpm restart
Gracefully shutting down php-fpm . done
Starting php-fpm done
[root@tianqi-01 php-fpm.d]# !ps

10.这就是多个池子的配置方法
12.22php-fpm的慢执行日志(非常有用)
vim /usr/local/php-fpm/etc/php-fpm.d/www.conf//加入如下内容
request_slowlog_timeout = 1 slowlog = /usr/local/php-fpm/var/log/www-slow.log
配置nginx的虚拟主机test.com.conf,把unix:/tmp/php-fcgi.sock改为unix:/tmp/www.sock
重新加载nginx服务
vim /data/wwwroot/test.com/sleep.php//写入如下内容
<?php echo “test slow log”; sleep(2);echo “done”; ?>
curl -x127.0.0.1:80 test.com/sleep.php
cat /usr/local/php-fpm/var/log/www-slow.log
在做php网站的时候,建议使用LNMP,因为我们可以分析php的慢执行日志
查询方法:
1.系统负载高,可以通过各种工具查,查出是哪个进程导致
2.PHP网站访问慢,通过查看慢执行日志
1.配置www.conf 在配置文件中加入
request_slowlog_timeout = 1 //超过一秒钟就要记录日志
slowlog = /usr/local/php-fpm/var/log/www-slow.log //日志放到该路径下
[root@tianqi-01 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
保存退出
2.查看语法错误,并重新加载
[root@tianqi-01 php-fpm.d]# /usr/local/php-fpm/sbin/php-fpm -t

说明:要查看具体的错误信息,可以开启php.ini内的display_error参数
[root@dl-001 etc]# cat /usr/local/php-fpm/var/log/www-slow.log [05-Jan-2018 21:13:15] [pool www] pid 3430 script_filename = /data/www/test.com/sleep.php [0x00007f616ec772d8] sleep() /data/www/test.com/sleep.php:3
12.23open_basedir
open_basedir 的作用是限制php在指定的目录里活动。
[root@dl-001 etc]# vim /usr/local/php-fpm/etc/php-fpm.d/test.conf # 添加如下代码 php_admin_value[open_basedir]=/data/www/test.com:/tmp/
