CentOS 6.x 开启Nginx和Php-fpm状态统计-原创手记-慕课网

Nginx和PHP-FPM都在安装的时候创建了一个状态页，用于统计Nginx和PHP-FPM的相关状态信息。下面介绍一下如何开启Nginx和PHP-FPM的状态统计，以及介绍各参数的含义。

(一)开启Nginx的状态统计以及各参数详解

在/etc/nginx/conf.d/(根据自己的Nginx路径)中创建nginx_status.conf，并添加如下内容:

[root@iZ256vh2adfZ conf.d]# cat nginx_status.conf server { listen 80; server_name 127.0.0.1; location /nginx_status { stub_status on; access_log off; #allow 127.0.0.1; #deny all; }}

重启Nginx：

[root@iZ256vh2adfZ vhost]# /etc/init.d/nginx restartnginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is oknginx: configuration file /usr/local/nginx/conf/nginx.conf test is successfulStopping nginx: [ OK ]Starting nginx: [ OK ]

测试：

[root@iZ256vh2adfZ conf.d]# curl 127.0.0.1:80/nginx_statusActive connections: 4 server accepts handled requests 8 8 12 Reading: 0 Writing: 1 Waiting: 3

(二)开启PHP-FPM的状态统计以及各参数详解

开启php-fpm.conf开用php-fpm状态功能：

vim php-fpm.conf:

pm.status_path = /phpfpm_status

默认情况下为/status，当然也可以改成/php_status等，我这里是改成/php_status啦

vim /etc/nginx/conf.d/php_fpm_status.conf

server {

listen 80;

server_name 127.0.0.1;

location /php_status {

fastcgi_pass 127.0.0.1:9000;

include fastcgi_params;

fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;

#allow x.x.x.x;

access_log off;

#deny all;

}

重启Nginx、PHP-FPM。

测试：

[root@iZ256vh2adfZ conf.d]# curl http://127.0.0.1/php_status

pool: www

process manager: dynamic

start time: 25/Feb/2017:10:27:57 +0800

start since: 7

accepted conn: 1

listen queue: 0

max listen queue: 0

listen queue len: 128

idle processes: 4

active processes: 1

total processes: 5

max active processes: 1

max children reached: 0

slow requests: 0

PHP-FPM status状态详解：

pool – fpm池子名称，大多数为wwwprocess manager – 进程管理方式,值：static, dynamic or ondemand. dynamicstart time – 启动日期,如果reload了php-fpm，时间会更新start since – 运行时长accepted conn – 当前池子接受的请求数listen queue – 请求等待队列，如果这个值不为0，那么要增加FPM的进程数量max listen queue – 请求等待队列最高的数量listen queue len – socket等待队列长度idle processes – 空闲进程数量active processes – 活跃进程数量total processes – 总进程数量max active processes – 最大的活跃进程数量（FPM启动开始算）max children reached - 大道进程最大数量限制的次数，如果这个数量不为0，那说明你的最大进程数量太小了，请改大一点。slow requests – 启用了php-fpm slow-log，缓慢请求的数量

nginx、php-fpm状态页可以通过带参数实现个性化，可以带参数json、xml、html并且前面三个参数可以分别和full做一个组合，下面以php-fpm status为例：

(1)json格式：

[root@iZ25fueqyvvZ vhost]# curl http://127.0.0.1/php_status?json

{"pool":"www","process manager":"dynamic","start time":1487989605,"start since":3187,"accepted conn":179,"listen queue":0,"max listen queue":0,"listen queue len":128,"idle processes":14,"active processes":1,"total processes":15,"max active processes":5,"max children reached":0}

(2)xml格式：

[root@iZ25fueqyvvZ vhost]# curl http://127.0.0.1/php_status?xml

<?xml version="1.0" ?>

<process-manager>dynamic</process-manager>

<start-time>1487989605</start-time>

<start-since>3246</start-since>

<accepted-conn>184</accepted-conn>

<listen-queue>0</listen-queue>

<max-listen-queue>0</max-listen-queue>

<listen-queue-len>128</listen-queue-len>

<idle-processes>14</idle-processes>

<active-processes>1</active-processes>

<total-processes>15</total-processes>

<max-active-processes>5</max-active-processes>

<max-children-reached>0</max-children-reached>

(3)html格式：

[root@iZ25fueqyvvZ vhost]# curl http://127.0.0.1/php_status?html

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

<head><title>PHP-FPM Status Page</title></head>

(4)full格式：

[root@iZ25fueqyvvZ vhost]# curl http://127.0.0.1/php_status?full

pool: www

process manager: dynamic

start time: 25/Feb/2017:10:26:45 +0800

max listen queue: 0

listen queue len: 128

此处省略了很多个PID！
