企业级zabbix监控实战——zabbix监控PHP服务【显哥出品，必为精品】

1.部署PHP服务

#上传php7.2版本的安装包
[root@web01 ~]# ls -l php72.tar.gz 
-rw-r--r-- 1 root root 16568111 2020-03-30 16:24 php72.tar.gz

#解压、安装、启动
[root@web01 ~/opt]# tar xf php72.tar.gz 
[root@web01 ~/opt]# yum localinstall -y /root/opt/php/packages/*.rpm
[root@web01 ~/opt]# systemctl  start php-fpm.service

#配置php配置文件（大概在217行）
[root@web01 ~]# vim /etc/php-fpm.d/www.conf 
pm.status_path = /phpfpm_status

2.nginx配置文件

server {
    listen       80;
    server_name  localhost;
    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }
    location ~ ^/(phpfpm_status)$ {
        root           html;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
        include        fastcgi_params;
        allow 127.0.0.1;
		deny all;
    }
    location /nginx_status {
	stub_status on;
	allow 127.0.0.1;
	deny all;
    }
}

#重启nginx服务及php-fpm服务
[root@web01 ~]# systemctl  restart  nginx  php-fpm.service

3.curl命令测试

[root@web01 ~]# curl http://127.0.0.1/phpfpm_status
pool:                 www
process manager:      dynamic
start time:           21/May/2020:10:11:13 +0800
start since:          44
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

4.编写监听脚本并赋予权限

[root@web01 /server/scripts]# vim phpfpm_status.sh
#!/bin/bash
PHPFPM_COMMAND=$1
PHPFPM_PORT=80

start_since(){
    /usr/bin/curl -s "http://127.0.0.1:"$PHPFPM_PORT"/phpfpm_status" |awk '/^start since:/ {print $NF}'
}

accepted_conn(){
    /usr/bin/curl -s "http://127.0.0.1:"$PHPFPM_PORT"/phpfpm_status" |awk '/^accepted conn:/ {print $NF}'
}

listen_queue(){
    /usr/bin/curl -s "http://127.0.0.1:"$PHPFPM_PORT"/phpfpm_status" |awk '/^listen queue:/ {print $NF}'
}

max_listen_queue(){
    /usr/bin/curl -s "http://127.0.0.1:"$PHPFPM_PORT"/phpfpm_status" |awk '/^max listen queue:/ {print $NF}'
}

listen_queue_len(){
    /usr/bin/curl -s "http://127.0.0.1:"$PHPFPM_PORT"/phpfpm_status" |awk '/^listen queue len:/ {print $NF}'
}

idle_processes(){
    /usr/bin/curl -s "http://127.0.0.1:"$PHPFPM_PORT"/phpfpm_status" |awk '/^idle processes:/ {print $NF}'
}

active_processes(){
    /usr/bin/curl -s "http://127.0.0.1:"$PHPFPM_PORT"/phpfpm_status" |awk '/^active processes:/ {print $NF}'
}

total_processes(){
    /usr/bin/curl -s "http://127.0.0.1:"$PHPFPM_PORT"/phpfpm_status" |awk '/^total processes:/ {print $NF}'
}

max_active_processes(){
    /usr/bin/curl -s "http://127.0.0.1:"$PHPFPM_PORT"/phpfpm_status" |awk '/^max active processes:/ {print $NF}'
}

max_children_reached(){
    /usr/bin/curl -s "http://127.0.0.1:"$PHPFPM_PORT"/phpfpm_status" |awk '/^max children reached:/ {print $NF}'
}

slow_requests(){
    /usr/bin/curl -s "http://127.0.0.1:"$PHPFPM_PORT"/phpfpm_status" |awk '/^slow requests:/ {print $NF}'
}

case $PHPFPM_COMMAND in
	start_since)
		start_since;
		;;
	accepted_conn)
		accepted_conn;
		;;
	listen_queue)
		listen_queue;
		;;
	max_listen_queue)
		max_listen_queue;
		;;
	listen_queue_len)
		listen_queue_len;
		;;
	idle_processes)
		idle_processes;
		;;
	active_processes)
		active_processes;
		;;
        total_processes)
                total_processes;
                ;;
        max_active_processes)
                max_active_processes;
                ;;
        max_children_reached)
                max_children_reached;
                ;;
        slow_requests)
                slow_requests;
                ;;
	    *)
		echo $"USAGE:$0 {start_since|accepted_conn|listen_queue|max_listen_queue|listen_queue_len|idle_processes|active_processes|total_processes|max_active_processes|max_children_reached|slow_requests}"
esac

#赋予脚本执行权限
[root@web01 /server/scripts]# chmod +x phpfpm_status.sh

5.编写zabbix监控项

#编写监控项代码
[root@web01 /server/scripts]# cat /etc/zabbix/zabbix_agentd.d/phpfpm_status.conf
UserParameter=phpfpm_status[*],/bin/bash /server/scripts/phpfpm_status.sh "$1"

#重启zabbix客户端
[root@web01 /server/scripts]# systemctl   restart   zabbix-agent

#zabbix客户端获取值测试
[root@web01 /server/scripts]# zabbix_agentd -t phpfpm_status[start_since]
phpfpm_status[start_since]                    [t|98]

#zabbix服务端获取值测试
[root@zabbix-server ~]# zabbix_get  -s 172.16.1.7 -k phpfpm_status[slow_requests]
