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.conf ?php-fpm.conf ?php-fpm.conf.default ?php.ini[root@sdwaqw etc]# vim php-fpm.confinclude = etc/php-fpm.d/*.conf[global]#定义全局参数pid = /usr/local/php-fpm/var/run/php-fpm.piderror_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#[www]#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
[root@sdwaqw etc]# mkdir /usr/local/php-fpm/etc/php-fpm.d[root@sdwaqw etc]# cd php-fpm.d[root@sdwaqw php-fpm.d]# ls[root@sdwaqw php-fpm.d]# vim www.conf ????????//新建配置文件写入以下内容[www]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-fpmgroup = php-fpm#定义php-fpm服务的用户pm = dynamicpm.max_children = 50pm.start_servers = 20pm.min_spare_servers = 5pm.max_spare_servers = 35pm.max_requests = 500rlimit_files = 1024#以上部分为进程相关信息[root@sdwaqw php-fpm.d]# vim zlinu.conf ???????????//在新建另一个配置文件，写入以下内容[sdwaqw]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-fpmgroup = php-fpm#定义php-fpm服务的用户pm = dynamicpm.max_children = 50pm.start_servers = 20pm.min_spare_servers = 5pm.max_spare_servers = 35pm.max_requests = 500rlimit_files = 1024#以上部分为进程相关信息3、验证配置

[root@sdwaqw php-fpm.d]# cd /usr/local/nginx/conf/vhost[root@sdwaqw vhost]# vim sdwaqw.confserver{ ??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; ????????}}[root@sdwaqw vhost]# /usr/local/nginx/sbin/nginx -tnginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is oknginx: 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
[root@sdwaqw vhost]# vim /usr/local/php-fpm/etc/php-fpm.d/zlinu.conf[sdwaqw]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-fpmgroup = php-fpm#定义php-fpm服务的用户pm = dynamicpm.max_children = 50pm.start_servers = 20pm.min_spare_servers = 5pm.max_spare_servers = 35pm.max_requests = 500rlimit_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[root@sdwaqw vhost]# /usr/local/php-fpm/sbin/php-fpm -t[19-Mar-2018 18:30:23] NOTICE: configuration file /usr/local/php-fpm/etc/php-fpm.conf test is successful[root@sdwaqw vhost]# /etc/init.d/php-fpm restartGracefully shutting down php-fpm . doneStarting php-fpm ?done2、检验慢日志
[root@sdwaqw vhost]# touch /usr/local/php-fpm/var/log/sdwaqw-slow.log[root@sdwaqw vhost]# chmod 777 /usr/local/php-fpm/var/log/sdwaqw-slow.log[root@sdwaqw vhost]# echo ‘<?php echo "slowlog test!"; sleep(2);echo "done"; ?>‘ > /data/wwwroot/sdwaqw/sleep.php[root@sdwaqw php-fpm.d]# curl -x127.0.0.1:80 sdwaqw.com/sleep.phpslowlog test!done[root@sdwaqw php-fpm.d]#[root@sdwaqw php-fpm.d]# cat /usr/local/php-fpm/var/log/sdwaqw-slow.log ????//查看蛮日志[19-Mar-2018 19:48:08] ?[pool sdwaqw] pid 2354script_filename = /data/wwwroot/sdwaqw/sleep.php[0x00007f8f0c1802e8] sleep() /data/wwwroot/sdwaqw/sleep.php:3[19-Mar-2018 19:53:29] ?[pool sdwaqw] pid 2356script_filename = /data/wwwroot/sdwaqw/sleep.php[0x00007f8f0c1802e8] 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。
[root@sdwaqw php-fpm.d]# vim /usr/local/php-fpm/etc/php-fpm.d/sdwaqw.conf ??//加入如下内容
php_admin_value[open_basedir]=/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。
