大家都知道,zabbix自定义key的功能十分方便,监控任意值都是特别的方便,安装好了之后,如果你需要监控mysql,用默认的模板是无法工作的,因为没有key的存在,所以要自己写一个脚本去实现key。当然也可以用https://www.zabbix.com/wiki/howto/monitor/db/mysql/extensive_mysql_monitoring_including_replication这里的php脚本,如果想监控主从同步状态,原理相同,此处不写了。
脚本可以用任意语言写,但是在linux下,还是shell最方便,用php,需要安装php环境,用python,需要安装python-MySQL库,用perl也是如此,所以选择了bash。bash脚本提供了用户名密码主机在web界面配置的功能,这里不写了,有问题的可以留言。
脚本位置zabbix-agent,脚本,配置文件ok后重启服务,web上面添加对应主机mysql模板(自带)
shell#cat /etc/zabbix/scripts/monitor_mysql #!/bin/bash #author:itnihao #mail:itnihao@qq.com #date 2013-12-18 #version v1.0 #function:use zabbix monitor mysql status mysql=$(which mysql) #注意,如果你的mysql是非标准安装,请写mysql的绝对路径 #mysql=/usr/bin/mysql var=$1 MYSQL_USER=$2 MYSQL_PASSWORD=$3 MYSQL_Host=$4 [ "${MYSQL_USER}" = '' ] && MYSQL_USER=zabbix [ "${MYSQL_PASSWORD}" = '' ] && MYSQL_PASSWORD=zabbix [ "${MYSQL_Host}" = '' ] && MYSQL_Host=localhost [ "${var}" = '' ] && echo ""||${mysql} -u${MYSQL_USER} -p${MYSQL_PASSWORD} -h${MYSQL_Host} -e 'show status'|grep -v Variable_name|grep "\b${var}\b"|awk '{print $2}'shell#egrep -v "(^#|^$)" /etc/zabbix/zabbix_agentd.conf #Server=这个参数,这里不详细的写了,主要改以下的参数 Include=/etc/zabbix/zabbix_agentd.conf.d/ #配置文件路径 UnsafeUserParameters=1 #允许特殊字符shell#cat /etc/zabbix/zabbix_agentd.conf.d/mysql_status.conf UserParameter=mysql.status[*],/etc/zabbix/scripts/monitor_mysql $1 UserParameter=mysql.ping,/usr/bin/mysqladmin -uzabbix -pzabbix ping|grep alive|wc -l UserParameter=mysql.version,mysql -V | cut -f6 -d" " | sed 's/,//'上面步骤好了之后用zabbix_get测试
shell#zabbix_get -s 127.0.0.1 -k mysql.status[Uptime]有数据即成功创建了可用key

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

MySQL is worth learning because it is a powerful open source database management system suitable for data storage, management and analysis. 1) MySQL is a relational database that uses SQL to operate data and is suitable for structured data management. 2) The SQL language is the key to interacting with MySQL and supports CRUD operations. 3) The working principle of MySQL includes client/server architecture, storage engine and query optimizer. 4) Basic usage includes creating databases and tables, and advanced usage involves joining tables using JOIN. 5) Common errors include syntax errors and permission issues, and debugging skills include checking syntax and using EXPLAIN commands. 6) Performance optimization involves the use of indexes, optimization of SQL statements and regular maintenance of databases.

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA
