Nginx自带监控模块ngx_http_stub_status_module提供Nginx的基本信息
在编译安装Nginx时加参数 --with-http_stub_status_module
安装好以后可以通过nginx -V|grep http_stub_status_module 查看状态模块是否已安装
PHP-FPM也自带监控，通过在php-fpm.conf中设置
pm.status_path = /php-fpm_status
就可以获取URL的方式获取PHP-FPM的状态
添加nginx_status.conf
server {
listen 80 ;
location /nginx_status {
stub_status on;
access_log off;
allow 127.0.0.1;
# allow 10.4.1.125;
deny all;
}
location /php-fpm_status {
fastcgi_pass 127.0.0.1:9000;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
