MPM主要用于监控mysql的各种参数性能指标,下面简单说一下他与zabbix的配置:
下面是它的配置文件关系图
主要包含两部分:
1、zabbix 模板:Template_FromDual.MySQL.*.xml
2、MPM agent perl 模块:FromDualMySQL*.pm
安装方法:
一、先安装MPM
下面是在linux 6.4下安装,先安装如下包:
yum install perl-File-Which perl-libwww-perl perl-Digest-SHA perl-DBD-MySQL perl-Time-HiRes \
perl-Crypt-SSLeay
解压缩下载的包:
tar xf mysql_performance_monitor-latest.tar.gz
tar xf mysql_performance_monitor_templates-latest.tar.gz
其中mysql_performance_monitor_templates-latest.tar.gz里面的内容,根据需要导入到zabbix server模板中,mysql_performance_monitor-latest.tar.gz解压后,放在zabbix的客户端中。
二、配置zabbix client
1、在客户端中解压相关脚本,并配置zabbix_agentd.conf文件,加入如下内容:
UserParameter=FromDual.MySQL.check,/opt/mysql_performance_monitor_agent/FromDualMySQLagent.pl /etc/zabbix/FromDualMySQLagent.conf
2、cp FromDualMySQLagent.conf.template /etc/zabbix/FromDualMySQLagent.conf
并修改相关内容:
[default] Type = mysqld LogFile = /var/log/zabbix/FromDualMySQLagent.log Username = root Password = <secret> MysqlHost = 127.0.0.1 MysqlPort = 3306 ZabbixServer = localhost Modules = process mysql myisam innodb [<db_server>] Type = mysqld Modules = mpm server [mysql1] ####这个名字必须与zabbix server增加的主机名保持一致。 Type = mysqld Modules = process mysql myisam innodb PidFile = /mysql/data/mysql.pid #mysql server pid
下面是监控用户在mysql数据库所需要的权限:
CREATE USER 'mpm'@'127.0.0.1' IDENTIFIED BY 'mpmsecret';
GRANT PROCESS ON *.* TO 'mpm'@'127.0.0.1';
GRANT REPLICATION CLIENT ON *.* TO 'mpm'@'127.0.0.1';
3、创建相关目录与文件,并加权限
mkdir -p /var/log/zabbix /var/log/zabbix/cache
chown -R zabbix: /var/log/zabbix /var/log/zabbix/cache
4、修改zabbix_send的在FromDualMySQLagent.pl脚本中的路径
FromDualMySQLagent.pl中zabbix_sender的路径。sed -i 's|/usr/local/bin|/usr/local/zabbix/bin/|g' FromDualMySQLagent.pl
5、启动agentd,service zabbix_agentd start
三、在zabbix服务端配置
1、导入相关的模板,其中Template_FromDual.MySQL.mpm.xml是必导的,其它可根据自己的需要再导入;
2、新增主机,并link到MPM模板上即可。
注意主机名必须与被监控的客户端主机名保持一致。
测试验证:
/usr/local/zabbixt/mpm/FromDualMySQLagent.pl /etc/zabbix/FromDualMySQLagent.conf
返回值为1:表示MPM插件正常,重启zabbix_agent,加载mpm插件
也可以放在crontab中定时进行监控
* * * * * /usr/local/zabbixt/mpm/FromDualMySQLagent.pl /etc/zabbix/FromDualMySQLagent.conf 1>/dev/null 2>&1

MySQL functions can be used for data processing and calculation. 1. Basic usage includes string processing, date calculation and mathematical operations. 2. Advanced usage involves combining multiple functions to implement complex operations. 3. Performance optimization requires avoiding the use of functions in the WHERE clause and using GROUPBY and temporary tables.

Efficient methods for batch inserting data in MySQL include: 1. Using INSERTINTO...VALUES syntax, 2. Using LOADDATAINFILE command, 3. Using transaction processing, 4. Adjust batch size, 5. Disable indexing, 6. Using INSERTIGNORE or INSERT...ONDUPLICATEKEYUPDATE, these methods can significantly improve database operation efficiency.

In MySQL, add fields using ALTERTABLEtable_nameADDCOLUMNnew_columnVARCHAR(255)AFTERexisting_column, delete fields using ALTERTABLEtable_nameDROPCOLUMNcolumn_to_drop. When adding fields, you need to specify a location to optimize query performance and data structure; before deleting fields, you need to confirm that the operation is irreversible; modifying table structure using online DDL, backup data, test environment, and low-load time periods is performance optimization and best practice.

Use the EXPLAIN command to analyze the execution plan of MySQL queries. 1. The EXPLAIN command displays the execution plan of the query to help find performance bottlenecks. 2. The execution plan includes fields such as id, select_type, table, type, possible_keys, key, key_len, ref, rows and Extra. 3. According to the execution plan, you can optimize queries by adding indexes, avoiding full table scans, optimizing JOIN operations, and using overlay indexes.

Subqueries can improve the efficiency of MySQL query. 1) Subquery simplifies complex query logic, such as filtering data and calculating aggregated values. 2) MySQL optimizer may convert subqueries to JOIN operations to improve performance. 3) Using EXISTS instead of IN can avoid multiple rows returning errors. 4) Optimization strategies include avoiding related subqueries, using EXISTS, index optimization, and avoiding subquery nesting.

Methods for configuring character sets and collations in MySQL include: 1. Setting the character sets and collations at the server level: SETNAMES'utf8'; SETCHARACTERSETutf8; SETCOLLATION_CONNECTION='utf8_general_ci'; 2. Create a database that uses specific character sets and collations: CREATEDATABASEexample_dbCHARACTERSETutf8COLLATEutf8_general_ci; 3. Specify character sets and collations when creating a table: CREATETABLEexample_table(idINT

To safely and thoroughly uninstall MySQL and clean all residual files, follow the following steps: 1. Stop MySQL service; 2. Uninstall MySQL packages; 3. Clean configuration files and data directories; 4. Verify that the uninstallation is thorough.

Renaming a database in MySQL requires indirect methods. The steps are as follows: 1. Create a new database; 2. Use mysqldump to export the old database; 3. Import the data into the new database; 4. Delete the old database.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
