配置zabbix监控nginx状态。

配置zabbix监控 Nginx状态。

首先搭建一套LNMP环境，部署discuz论坛用于后面监控案例。
搭建一个测试用论坛**

一、搭建Discuz论坛

1、配置epel源

[root@node4 ~]# wget -O /etc/yum.repos.d/epel.repo Http://mirrors.aliyun.com/repo/epel-7.repo

2、安装Centos-release-scl源

[root@node4 ~]# yum install centos-release-scl -y

3、部署lnmp环境

[root@node4 ~]# yum -y install nginx mariadb-server rh-PHP72-php rh-php72-phpcli rh-php72-php-common \rh-php72-php-fpm rh-php72-php-gd rh-php72-php-mbstring rh-php72-php-pdo \rh-php72-php-xml rh-php72-php-Mysqlnd rh-Redis5 sclo-php72-php-pecl-redis5

4、配置php-fpm

[root@node4 ~]# vim /etc/opt/rh/rh-php72/php-fpm.d/www.conf; Unix user/group of processes; Note: The user is mandatory. If the group is not set, the default user's group;       will be used.; RPM: apache user chosen to provide access to the same directories as httpd;user = apacheuser = nginx; RPM: Keep a group allowed to write in log dir.;group = apachegroup = nginx

5、准备论坛代码

[root@node4 ~]# mkdir /code/discuz -p论坛代码可到官网下载：https://www.discuz.net/forum-10-1.html上传下载的Discuz_X3.3_SC_UTF8.zip[root@node4 ~]# rz -Erz waiting to receive.[root@node4 ~]# lsanaconda-ks.cfg  Discuz_X3.3_SC_UTF8.zip解压到创建的指定目录下[root@node4 ~]# unzip -q Discuz_X3.3_SC_UTF8.zip -d /code/discuz/[root@node4 ~]# cd /code/discuz[root@node4 discuz]# lltotal 4drwxr-xr-x  2 root root  102 Jul 27  2017 readmedrwxr-xr-x 12 root root 4096 Jul 27  2017 uploaddrwxr-xr-x  4 root root   72 Jul 27  2017 utility修改所属组[root@node4 discuz]# chown -R nginx:nginx /code/discuz/

6、配置论坛首页

[root@node4 ~]# vim /etc/nginx/conf.d/discuz.confserver {        listen 80;        server_name discuz.kongd.com;        root /code/discuz/upload;        location / {        index index.php index.html;        }        location ~ \.php$ {        fastcgi_pass 127.0.0.1:9000;        fastcgi_index index.php;        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;        include fastcgi_params;        }}

7、启动服务

先停止之前的apache(没有则不用此操作)：# systemctl stop httpd[root@node4 ~]# systemctl enable nginx.service mariadb.service rh-php72-php-fpm.service rh-redis5-redis.service --nowCreated symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service.Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.Created symlink from /etc/systemd/system/multi-user.target.wants/rh-php72-php-fpm.service to /usr/lib/systemd/system/rh-php72-php-fpm.service.Created symlink from /etc/systemd/system/multi-user.target.wants/rh-redis5-redis.service to /usr/lib/systemd/system/rh-redis5-redis.service.

8、配置论坛用数据库

创建数据库并授权[root@node4 ~]# mysql -e "create database discuz character set utf8;"[root@node4 ~]# mysql -e "grant all on discuz.* to discuz@localhost identified by '123456';"

配置hosts解析，在线完成论坛安装

C:\windows\System32\drivers\etc\hosts
添加：192.168.43.114 discuz.kongd.com

9、登录后台，配置redis加速

修改config_global.php文件

[root@node4 ~]# vim /code/discuz/upload/config/config_global.php// --------------------------  CONFIG MEMORY  --------------------------- //$_config['memory']['prefix'] = 'QOatDb_';$_config['memory']['redis']['server'] = '127.0.0.1';//redis服务地址$_config['memory']['redis']['port'] = 6379;$_config['memory']['redis']['pconnect'] = 1;$_config['memory']['redis']['timeout'] = '0';$_config['memory']['redis']['requirepass'] = '';//认证密码，没配置不填$_config['memory']['redis']['serializer'] = 1;$_config['memory']['memcache']['server'] = '';$_config['memory']['memcache']['port'] = 11211;$_config['memory']['memcache']['pconnect'] = 1;

二、Nginx监控原理

Nginx提供了status模块监控内部的运行状态，如需查看当前Nginx是否支持status模块，则可使用nginx -V命令查看是否输出–with_stub_status_modules。 RPM包安装默认支持，为 --withhttp_stub_status_module 。

三、Nginx状态数据配置的开启

开启Nginx状态数据配置，需要在nginx.conf中添加一个虚拟主机，内容如下

[root@node4 ~]# cat /etc/nginx/conf.d/monitor.confserver {listen 127.0.0.1:80;server_name 127.0.0.1;location /nginxstatus {stub_status on;#开启状态页access_log off;#不记录访问日志allow 127.0.0.1; #只允许自己访问，这里是允许的IP地址deny all;#其他全部拒绝}}-----------------------------------------------------------------------------------------------------------------------检查配置文件[root@node4 ~]# nginx -tnginx: the configuration file /etc/nginx/nginx.conf syntax is oknginx: configuration file /etc/nginx/nginx.conf test is successful-----------------------------------------------------------------------------------------------------------------------加载配置[root@node4 ~]# nginx -s reload-----------------------------------------------------------------------------------------------------------------------访问测试[root@node4 ~]# curl http://127.0.0.1/nginxstatusActive connections: 1 server accepts handled requests 19 19 112 Reading: 0 Writing: 1 Waiting: 0 各字段的含义：Active connections：当前活跃的客户端连接数，包括Waiting连接数；accepts：接受的客户端连接总数；handled：已处理的连接总数。通常与“accepts”的值相同，除非达到某些资源限制，如“worker_connections”；requests：客户端请求总数，一个客户端连接可能包含多个请求；Reading：Nginx正在读取请求标头的当前连接数；Writing：Nginx正在将响应写回给客户端的当前连接数；Waiting：当前等待请求的空闲连接数。
