zabbix监控nginx
a机器:zabbix服务端(192.168.234.128) b机器:zabbix客户端(192.168.234.125)
在b机器(zabbix客户端)操作:
编辑nginx虚拟主机配置文件:
[root@centos ~]# vi /etc/nginx/conf.d/default.conf
在server{}中添加以下内容:
location /nginx_status { stub_status on; access_log off; allow 127.0.0.1; deny all; }
重载nginx配置:
[root@centos ~]# nginx -s reload
测试:
[root@centos ~]# curl http://127.0.0.1/nginx_status active connections: 1 server accepts handled requests 3 3 3 reading: 0 writing: 1 waiting: 0
#nginx状态信息已显示
状态说明:
添加监控脚本:
vi /usr/local/sbin/ngx_status.sh
添加以下内容:
#!/bin/bash url="http://127.0.0.1/nginx_status" curl=/usr/bin/curl # 检测nginx进程是否存在 function ping { /sbin/pidof nginx | wc -l } # 检测nginx性能 function active { $curl $url 2>/dev/null| grep 'active' | awk '{print $nf}' } function reading { $curl $url 2>/dev/null| grep 'reading' | awk '{print $2}' } function writing { $curl $url 2>/dev/null| grep 'writing' | awk '{print $4}' } function waiting { $curl $url 2>/dev/null| grep 'waiting' | awk '{print $6}' } function accepts { $curl $url 2>/dev/null| awk nr==3 | awk '{print $1}' } function handled { $curl $url 2>/dev/null| awk nr==3 | awk '{print $2}' } function requests { $curl $url 2>/dev/null| awk nr==3 | awk '{print $3}' } $1
添加权限:
[root@centos ~]# chmod 755 /usr/local/sbin/ngx_status.sh
编辑zabbix_agent配置文件:
[root@centos ~]# vi /etc/zabbix/zabbix_agentd.conf
在option:userparameter处添加:userparameter=nginx.status[*],/usr/local/sbin/ngx_status.sh $1
重启服务:
[root@centos ~]# systemctl restart zabbix-agent
在a机器(服务端)测试:
[root@zabbix ~]# zabbix_get -s 192.168.234.125 -k 'nginx.status[accepts]' 6
在本机创建.xml文件并添加以下内容:(文件名称自定义)

zabbix监控tomcat
a机器:zabbix服务端(192.168.234.128) b机器:zabbix客户端(192.168.234.125)
在a机器安装zabbix-java-gateway:
[root@zabbix ~]# wget https://mirrors.tuna.tsinghua.edu.cn/zabbix/zabbix/4.0/rhel/7/x86_64/zabbix-java-gateway-4.0.14-1.el7.x86_64.rpm [root@zabbix ~]# yum -y localinstall zabbix-java-gateway-4.0.14-1.el7.x86_64.rpm
编辑gateway配置文件:
[root@zabbix ~]# vi /etc/zabbix/zabbix_java_gateway.conf
去掉listen_ip、listen_port(监听端口)、start_pollers(进程数)的注释符号#:
#listen_ip定义被监控机器的地址,不指定默认监听全部机器
编辑server配置文件:
[root@zabbix ~]# vi /etc/zabbix/zabbix_server.conf
定义以下3个配置参数:
启动zabbix-java-gateway服务:
[root@zabbix ~]# systemctl start zabbix-java-gateway
重启zabbix-server服务:
[root@zabbix ~]# systemctl restart zabbix-server
查看监听端口:
[root@zabbix ~]# netstat -lntp |grep java tcp6 0 0 :::10052 :::* listen 8706/java
开启jmx
在b机器编辑tomcat配置文件:
[root@centos ~]# vi /usr/local/tomcat/bin/catalina.sh
添加以下内容:
export catalina_opts="$catalina_opts -dcom.sun.management.jmxremote -djava.rmi.server.hostname=192.168.234.125 -dcom.sun.management.jmxremote.port=9999 -dcom.sun.management.jmxremote.ssl=false -dcom.sun.management.jmxremote.authenticate=false"
#hostname定义b机器地址,端口9999(默认12345)
重启tomcat:
[root@centos ~]# /usr/local/tomcat/bin/shutdown.sh [root@centos ~]# /usr/local/tomcat/bin/startup.sh
查看监听端口9999:
[root@centos ~]# netstat -lntp |grep 9999 tcp6 0 0 :::9999 :::* listen 25861/java
进入zabbix前端页面添加主机:
#与普通情况添加监控主机不同,监控b机器的tomcat需要配置jmx接口
模板链接jmx相关的两个模板:
当jmx图标变绿即表示配置成功:
zabbix监控mysql
a机器:zabbix服务端(192.168.234.128) b机器:zabbix客户端(192.168.234.125)
zabbix_agent定义mysql监控的配置文件:/etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf
在b机器登录mysql创建用户:
mysql> grant usage,process,replication client on *.* to zamysql@'localhost' identified by 'zamysql';
创建配置文件指定的目录:
[root@centos ~]# mkdir /var/lib/zabbix
创建my.cnf文件:
[root@centos ~]# vi /var/lib/zabbix/.my.cnf
#需要注意该文件是隐藏文件
添加以下内容:
[mysql] host=localhost user=zamysql password='zamysql' socket=/tmp/mysql.sock [mysqladmin] host=localhost user=zamysql password='zamysql' socket=/tmp/mysql.sock
在a机器测试:
[root@zabbix ~]# zabbix_get -s 192.168.234.125 -p 10050 -k mysql.ping 1 [root@zabbix ~]# zabbix_get -s 192.168.234.125 -p 10050 -k mysql.version mysql ver 14.14 distrib 5.6.43, for linux-glibc2.12 (x86_64) using editline wrapper [root@zabbix ~]# zabbix_get -s 192.168.234.125 -p 10050 -k mysql.size 10240

The above is the detailed content of How to monitor Nginx/Tomcat/MySQL with zabbix. For more information, please follow other related articles on the PHP Chinese website!

The reason why NGINX is popular is its advantages in speed, efficiency and control. 1) Speed: Adopt asynchronous and non-blocking processing, supports high concurrent connections, and has strong static file service capabilities. 2) Efficiency: Low memory usage and powerful load balancing function. 3) Control: Through flexible configuration file management behavior, modular design facilitates expansion.

The differences between NGINX and Apache in terms of community, support and resources are as follows: 1. Although the NGINX community is small, it is active and professional, and official support provides advanced features and professional services through NGINXPlus. 2.Apache has a huge and active community, and official support is mainly provided through rich documentation and community resources.

NGINXUnit is an open source application server that supports a variety of programming languages and frameworks, such as Python, PHP, Java, Go, etc. 1. It supports dynamic configuration and can adjust application configuration without restarting the server. 2.NGINXUnit supports multi-language applications, simplifying the management of multi-language environments. 3. With configuration files, you can easily deploy and manage applications, such as running Python and PHP applications. 4. It also supports advanced configurations such as routing and load balancing to help manage and scale applications.

NGINX can improve website performance and reliability by: 1. Process static content as a web server; 2. forward requests as a reverse proxy server; 3. allocate requests as a load balancer; 4. Reduce backend pressure as a cache server. NGINX can significantly improve website performance through configuration optimizations such as enabling Gzip compression and adjusting connection pooling.

NGINXUnit simplifies application deployment with dynamic configuration and multilingual support. 1) Dynamic configuration can be modified without restarting the server. 2) Supports multiple programming languages, such as Python, PHP, and Java. 3) Adopt asynchronous non-blocking I/O model to improve high concurrency processing performance.

NGINX initially solved the C10K problem and has now developed into an all-rounder who handles load balancing, reverse proxying and API gateways. 1) It is well-known for event-driven and non-blocking architectures and is suitable for high concurrency. 2) NGINX can be used as an HTTP and reverse proxy server, supporting IMAP/POP3. 3) Its working principle is based on event-driven and asynchronous I/O models, improving performance. 4) Basic usage includes configuring virtual hosts and load balancing, and advanced usage involves complex load balancing and caching strategies. 5) Common errors include configuration syntax errors and permission issues, and debugging skills include using nginx-t command and stub_status module. 6) Performance optimization suggestions include adjusting worker parameters, using gzip compression and

Diagnosis and solutions for common errors of Nginx include: 1. View log files, 2. Adjust configuration files, 3. Optimize performance. By analyzing logs, adjusting timeout settings and optimizing cache and load balancing, errors such as 404, 502, 504 can be effectively resolved to improve website stability and performance.
