安装配置Zabbix来监控MySQL的基本教程_MySQL
Zabbix的简单安装配置说明
1、在已有的LAMP或者LNMP的基础上安装zabbix,安装一些依赖包:
yum -y install mysql-devel libcurl-devel net-snmp-devel
2、添加用户:
groupadd zabbix useradd zabbix -g zabbix
3、创建数据库,添加授权账号
create database zabbix character set utf8; grant all privileges on zabbix.* to zabbix@localhost identified by 'zabbix';
4、编译安装zabbix
下载地址:
wget http://jaist.dl.sourceforge.net/project/zabbix/ZABBIX%20Latest%20Stable/2.2.0/zabbix-2.2.0.tar.gz tar zxf zabbix-2.2.0.tar.gz cd zabbix-2.2.0 ./configure --prefix=/usr/local/zabbix --enable-server --enable-agent \ --with-mysql --with-net-snmp --with-libcurl make install
5、导入数据库
mysql -uzabbix -pzabbix -hlocalhost zabbix < database/mysql/schema.sql mysql -uzabbix -pzabbix -hlocalhost zabbix < database/mysql/images.sql mysql -uzabbix -pzabbix -hlocalhost zabbix < database/mysql/data.sql
6、修改配置文件
cp misc/init.d/fedora/core/zabbix_server /etc/init.d/ cp misc/init.d/fedora/core/zabbix_agentd /etc/init.d/ cp -R frontends/php /var/www/html/zabbix sed -i 's/^DBUser=.*$/DBUser=zabbix/g' /usr/local/zabbix/etc/zabbix_server.conf sed -i 's/^.*DBPassword=.*$/DBPassword=zabbix/g' /usr/local/zabbix/etc/zabbix_server.conf sed -i 's/BASEDIR=\/usr\/local/BASEDIR=\/usr\/local\/zabbix/g' /etc/init.d/zabbix_server sed -i 's/BASEDIR=\/usr\/local/BASEDIR=\/usr\/local\/zabbix/g' /etc/init.d/zabbix_agentd
7、添加服务端口:
cat >>/etc/services <<EOF zabbix-agent 10050/tcp Zabbix Agent zabbix-agent 10050/udp Zabbix Agent zabbix-trapper 10051/tcp Zabbix Trapper zabbix-trapper 10051/udp Zabbix Trapper EOF
8、启动服务
/etc/init.d/zabbix_server start /etc/init.d/zabbix_agentd start echo "/etc/init.d/zabbix_server start" >> /etc/rc.local echo "/etc/init.d/zabbix_agentd start" >> /etc/rc.local
9、web页面配置,配置http访问好了后web登陆:http://ip/zabbix
zabbix监控mysql性能
通过获取mysql状态值将这些状态值传递给服务器并绘制成图片,这样可以观察mysql的工作情况,通常需要获得状态变量有以下
- Com_update:mysql执行的更新个数
- Com_select:mysql执行的查询个数
- Com_insert:mysql执行插入的个数
- Com_delete:执行删除的个数
- Com_rollback:执行回滚的操作个数
- Bytes_received:接受的字节数
- Bytes_sent:发送的字节数
- Slow_queries:慢查询语句的个数
1、创建mysql性能监控脚本
#!/bin/bash #Create by zhengdazhi 2014.09.22 MYSQL_DIR=/usr/local/mysql MYSQL=${MYSQL_DIR}/bin/mysql MYSQLADMIN=${MYSQL_DIR}/bin/mysqladmin MYSQL_SOCK="/tmp/mysql.sock" MYSQL_USER=root MYSQL_PWD=root ARGS=1 if [ $# -ne "$ARGS" ];then echo "Please input one arguement:" fi case $1 in Uptime) result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK status|cut -f2 -d":"|cut -f1 -d"T"` echo $result ;; Com_update) result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_update"|cut -d"|" -f3` echo $result ;; Slow_queries) result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK status |cut -f5 -d":"|cut -f1 -d"O"` echo $result ;; Com_select) result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_select"|cut -d"|" -f3` echo $result ;; Com_rollback) result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_rollback"|cut -d"|" -f3` echo $result ;; Questions) result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK status|cut -f4 -d":"|cut -f1 -d"S"` echo $result ;; Com_insert) result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_insert"|cut -d"|" -f3` echo $result ;; Com_delete) result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_delete"|cut -d"|" -f3` echo $result ;; Com_commit) result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_commit"|cut -d"|" -f3` echo $result ;; Bytes_sent) result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Bytes_sent" |cut -d"|" -f3` echo $result ;; Bytes_received) result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Bytes_received" |cut -d"|" -f3` echo $result ;; Com_begin) result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_begin"|cut -d"|" -f3` echo $result ;; *) echo "Usage:$0(Uptime|Com_update|Slow_queries|Com_select|Com_rollback|Questions)" ;; esac
2、修改客户端配置文件
查看zabbix自带的mysql监控模板
可以看出该模板是读取 mysql.status的键,因此在客户端配置文件中加入的自定义键名也应该是mysql.status
vim /usr/local/zabbix_agentd/etc/zabbix_agentd.conf #开启用户自定义配置 UnsafeUserParameters=1 #添加mysql监控 UserParameter=mysql.status[*],/usr/local/zabbix_agent/bin/checkmysqlperformance.sh $1 $2
重启客户端
3、测试
[root@localhost bin]# ./zabbix_get -s 127.0.0.1 -k mysql.status[Com_update] 77503
4、将模板加入主机

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

Apache connects to a database requires the following steps: Install the database driver. Configure the web.xml file to create a connection pool. Create a JDBC data source and specify the connection settings. Use the JDBC API to access the database from Java code, including getting connections, creating statements, binding parameters, executing queries or updates, and processing results.

The process of starting MySQL in Docker consists of the following steps: Pull the MySQL image to create and start the container, set the root user password, and map the port verification connection Create the database and the user grants all permissions to the database

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

The key to installing MySQL elegantly is to add the official MySQL repository. The specific steps are as follows: Download the MySQL official GPG key to prevent phishing attacks. Add MySQL repository file: rpm -Uvh https://dev.mysql.com/get/mysql80-community-release-el7-3.noarch.rpm Update yum repository cache: yum update installation MySQL: yum install mysql-server startup MySQL service: systemctl start mysqld set up booting

Laravel is a PHP framework for easy building of web applications. It provides a range of powerful features including: Installation: Install the Laravel CLI globally with Composer and create applications in the project directory. Routing: Define the relationship between the URL and the handler in routes/web.php. View: Create a view in resources/views to render the application's interface. Database Integration: Provides out-of-the-box integration with databases such as MySQL and uses migration to create and modify tables. Model and Controller: The model represents the database entity and the controller processes HTTP requests.
