zabbix监控nginx的服务状态

1. 搭建zabbix

zabbix是基于lnmp架构的，所以在搭建zabbix之前需要先搭建lnmp架构，前面文章有写到如何搭建，可以参考文章LNMP架构

安装依赖包

[root@node2 ~]# yum -y install net-snmp-devel libevent-devel

下载zabbix

[root@node2 ~]# wget https://cdn.zabbix.com/zabbix/sources/stable/5.0/zabbix-5.0.2.tar.gz
[root@node2 ~]# ls
zabbix-5.0.1.tar.gz
[root@node2 ~]# tar xf zabbix-5.0.1.tar.gz

创建zabbix用户和组

[root@node2 ~]# useradd -r -M -s /sbin/nologin zabbix
[root@node2 ~]# id zabbix
uid=304(zabbix) gid=304(zabbix) 组=304(zabbix)

配置zabbix数据库

[root@node2 ~]# mysql -uroot -p123
mysql> create database zabbix character set utf8 collate utf8_bin;
Query OK, 1 row affected (0.00 sec)

mysql> grant all privileges on zabbix.* to zabbix@localhost identified by '123';
Query OK, 0 rows affected, 2 warnings (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)

mysql> quit
Bye

[root@node2 ~]# cd zabbix-5.0.1/database/mysql/
[root@node2 mysql]# ls
data.sql    images.sql   Makefile.in
double.sql  Makefile.am  schema.sql
[root@node2 mysql]# mysql -uroot -p123 zabbix < schema.sql 
[root@node2 mysql]# mysql -uroot -p123 zabbix < images.sql 
[root@node2 mysql]# mysql -uroot -p123 zabbix < data.sql 

编译安装zabbix

[root@node2 ~]# cd zabbix-5.0.1
[root@node2 zabbix-5.0.1]# ./configure --enable-server \
--enable-agent \
--with-mysql \
--with-net-snmp \
--with-libcurl \
--with-libxml2
[root@node2 zabbix-5.0.1]# make install

配置zabbix服务端

[root@node2 ~]# cd /usr/local/etc/
[root@node2 etc]# ls
zabbix_agentd.conf    zabbix_server.conf
zabbix_agentd.conf.d  zabbix_server.conf.d
[root@node2 etc]# vim zabbix_server.conf
...
### Option: DBPassword
#       Database password.
#       Comment this line if no password is used.
#
# Mandatory: no
# Default:
DBPassword=123  //将此行注释取消，并改为DBPassword=你的数据库登录密码，我这里为123

//启动服务
[root@node2 etc]# zabbix_server 
[root@node2 etc]# zabbix_agentd  
[root@node2 etc]# ss -antl |grep -E '10051|10050'
LISTEN     0      128          *:10050                    *:*                  
LISTEN     0      128          *:10051                    *:* 

配置zabbix服务web界面

//这里如果不修改后面访问web界面安装的时候会报错
[root@node2 ~]# sed -ri 's/(post_max_size =).*/\1 16M/g' /etc/php.ini
[root@node2 ~]# sed -ri 's/(max_execution_time =).*/\1 300/g' /etc/php.ini
[root@node2 ~]# sed -ri 's/(max_input_time =).*/\1 300/g' /etc/php.ini
[root@node2 ~]# sed -i '/;date.timezone/a date.timezone = Asia/Shanghai' /etc/php.ini
[root@node2 ~]# service php-fpm restart
Gracefully shutting down php-fpm . done
Starting php-fpm  done

//配置web界面
[root@node2 ~]# cd zabbix-5.0.1
[root@node2 zabbix-5.0.1]# cp -a ui /usr/local/nginx/html/zabbix
[root@node2 zabbix-5.0.1]# chown -R nginx.nginx /usr/local/nginx/html/zabbix/

//配置nginx虚拟主机
[root@node2 ~]# vim /usr/local/nginx/conf/nginx.conf
...
location / {
            root   html/zabbix;   //这里修改为zabbix的web界面目录
            index  index.php index.html index.htm;
        }
...
location ~ \.php$ {
            root           html/zabbix;  //这里修改为zabbix的web界面目录
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        fastcgi_params;
        }
...
//设置zabbix/conf目录的权限，让zabbix有权限生成配置文件zabbix.conf.php
[root@node2 ~]# chmod 777 /usr/local/nginx/html/zabbix/conf

//重载配置文件
[root@node2 ~]# nginx -s reload

访问web界面

2. 开启状态页面

[root@node2 ~]# vim /usr/local/nginx/conf/nginx.conf
...
        location /status {
            stub_status on;
            allow 192.168.207.0/24;
            deny all;
        }
...
[root@node2 ~]# nginx -s reload

访问

3. 配置监控脚本

[root@node2 ~]# ls /scripts/
check_nginx.sh
[root@node2 ~]# cd /scripts/
[root@node2 scripts]# cat check_nginx.sh 
#!/bin/bash

function handled()
{
    status=$(curl -s http://192.168.207.130/status |awk 'NR==3{print $3}')
    echo $status
}

function Reading()
{
    status=$(curl -s http://192.168.207.130/status |awk 'NR==4{print $2}')
    echo $status
}

function Writing()
{
    status=$(curl -s http://192.168.207.130/status |awk 'NR==4{print $4}')
    echo $status
}

case $1 in
    Writing)
	    Writing
	    ;;
    handled)
	    handled
	    ;;
    Reading)
	    Reading
	    ;;
    *)
	    echo "$0 handled|Writing|Reading"
	    ;;
esac
[root@node2 scripts]# chmod +x check_nginx.sh 

4. 编辑zabbix_agent配置文件

[root@node2 ~]# vim /usr/local/etc/zabbix_agentd.conf
...
# Default:
UnsafeUserParameters=1  //将此行取消注释，并将0改为1
...
# Default:
UserParameter=check_nginx[*],/bin/bash /scripts/check_nginx.sh $1

[root@node2 ~]# pkill zabbix
[root@node2 ~]# zabbix_server 
[root@node2 ~]# zabbix_agentd

//测试key是否可用
[root@node2 ~]# zabbix_get -s 127.0.0.1 -k check_nginx[handled]
107
[root@node2 ~]# zabbix_get -s 127.0.0.1 -k check_nginx[Reading]
0
[root@node2 ~]# zabbix_get -s 127.0.0.1 -k check_nginx[Writing]
1
