php-fpm的pool
　　php-fpm配置文件php-fpm.conf可以设置多个pool，在其中一个pool资源耗尽，会导致其他站点无法访问资源，报502错误。有必要把站点进行分离，分别使用单独的pool。

1、修改配置文件

pear.confphp-fpm.confphp-fpm.conf.defaultphp.ini
# vim php-fpm.conf
include = etc/php-fpm.d/*.conf
#定义全局参数
pid = /usr/local/php-fpm/var/run/php-fpm.pid
error_log = /usr/local/php-fpm/var/log/php-fpm.log#添加上面这行，暂时注释掉下面的pool##listen = /tmp/php-fcgi.sock#监听地址，也可以写：listen = 127.0.0.1:9000，本地监听，也可以监听其他IP：port#此处格式会影响配置Nginx和PHP结合时Nginx寻址PHP的路径#listen.mode = 666#当监听的为socket文件时该部分才生效，用于指定.sock文件的权限#user = php-fpm#group = php-fpm#定义php-fpm服务的用户#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#以上部分为进程相关信息
2、创建配置文件目录和子配置文件

# mkdir /usr/local/php-fpm/etc/php-fpm.d
# cd php-fpm.d
# ls
# vim www.conf       //新建配置文件写入以下内容

listen = /tmp/www.sock#监听地址，也可以写：listen = 127.0.0.1:9000，本地监听，也可以监听其他IP：port#此处格式会影响配置Nginx和PHP结合时Nginx寻址PHP的路径
listen.mode = 666#当监听的为socket文件时该部分才生效，用于指定.sock文件的权限
user = php-fpm
group = php-fpm#定义php-fpm服务的用户
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#以上部分为进程相关信息
# vim zlinu.conf          //在新建另一个配置文件，写入以下内容

listen = /tmp/sdwaqw.sock#监听地址，也可以写：listen = 127.0.0.1:9000，本地监听，也可以监听其他IP：port#此处格式会影响配置Nginx和PHP结合时Nginx寻址PHP的路径
listen.mode = 666#当监听的为socket文件时该部分才生效，用于指定.sock文件的权限
user = php-fpm
group = php-fpm#定义php-fpm服务的用户
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#以上部分为进程相关信息
3、验证配置

# /etc/init.d/php-fpm restart

php-fpm 26100.00.2 2271804732 ?    S 18:08 0:00 php-fpm: pool sdwaqw
4、修改虚拟主机配置文件，为站点配置pool

# cd /usr/local/nginx/conf/vhost
# vim sdwaqw.conf
server
{
listen 80 default_server;#有default_server标记的就是默认虚拟主机
server_name sdwaqwtest.com;
index index.html index.htm index.php;
root /data/wwwroot/sdwaqw;
location ~ \.php$
{
include fastcgi_params;
# 这里写对应php-fpm.conf内设置的sock
fastcgi_pass unix:/tmp/sdwaqw.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /data/wwwroot/sdwaqw$fastcgi_script_name;
}
}
# /usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
以上为分别设置pool，单独保存在文件夹。也可以直接在pool-fpm.conf中添加多个pool，站点调用对应的就行。
二、php-fpm的慢执行日志

1、编辑配置文件

# vim /usr/local/php-fpm/etc/php-fpm.d/zlinu.conf

listen = /tmp/sdwaqw.sock#监听地址，也可以写：listen = 127.0.0.1:9000，本地监听，也可以监听其他IP：port#此处格式会影响配置Nginx和PHP结合时Nginx寻址PHP的路径
listen.mode = 666#当监听的为socket文件时该部分才生效，用于指定.sock文件的权限
user = php-fpm
group = php-fpm#定义php-fpm服务的用户
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#以上部分为进程相关信息
request_slowlog_timeout = 1#当请求超过1秒开始记录日志
slowlog = /usr/local/php-fpm/var/log/sdwaqw-slow.log#日志存放地址
# /usr/local/php-fpm/sbin/php-fpm -t
NOTICE: configuration file /usr/local/php-fpm/etc/php-fpm.conf test is successful
# /etc/init.d/php-fpm restart
Gracefully shutting down php-fpm .
done
Starting php-fpmdone
2、检验慢日志

# touch /usr/local/php-fpm/var/log/sdwaqw-slow.log
# chmod 777 /usr/local/php-fpm/var/log/sdwaqw-slow.log
# echo '' > /data/wwwroot/sdwaqw/sleep.php
# curl -x127.0.0.1:80 sdwaqw.com/sleep.php
slowlog test!done#
# cat /usr/local/php-fpm/var/log/sdwaqw-slow.log //查看蛮日志
pid 2354
script_filename = /data/wwwroot/sdwaqw/sleep.php
sleep() /data/wwwroot/sdwaqw/sleep.php:3
pid 2356
script_filename = /data/wwwroot/sdwaqw/sleep.php
sleep() /data/wwwroot/sdwaqw/sleep.php:3
三、php-fphp-fpm定义open_basedir
　　当一台服务器跑多个站点时，使用openbasedir限定各个站点所能访问的服务器上的目录的范围。在php-fpm服务中，可以针对每个pool设定open basedir。
# vim /usr/local/php-fpm/etc/php-fpm.d/sdwaqw.conf //加入如下内容
php_admin_value=/data/wwwroot/sdwaqw:/tmp/

四、php-fpm进程管理
　　pm = dynamic
;动态进程管理，也可以是static
;只有此处设置为dynamic，下面的配置才生效
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
;定义空闲时段，子进程数的最小数量，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请求，当达到这个数值时，他会自动退出。
