zabbix监控mariadb

坑有点多…

由于我是自己手动编译的zabbix,因此很多配置不能按照官方文档来,要进行一定修改

首先我的zabbix的路径为/usr/local/zabbix

按照官方给的文档的说法:https://www.zabbix.com/integrations/mysql

我需要把template_db_mysql.conf复制到zabbix_agentd.d目录中去,需要特别注意的是,配置文件默认是不引用这个目录中的配置文件的,要手动打开引用。

其次我试了大半天也没试出来.my.cnf正确的路径,看到网上( https://www.zabbix.com/forum/zabbix-troubleshooting-and-problems/34520-newbie-question-why-won-t-zabbix-see-the-my-cnf-file )有人直接把密码写进去了,试了试发现可以

template_db_mysql.conf

注意-u -p 一定要紧挨用户名和密码,否则报错

#template_db_mysql.conf created by Zabbix for "Template DB MySQL" and Zabbix 4.2
#For OS Linux: You need create .my.cnf in zabbix-agent home directory (/var/lib/zabbix by default)
#For OS Windows: You need add PATH to mysql and mysqladmin and create my.cnf in %WINDIR%my.cnf,C:my.cnf,BASEDIRmy.cnf https://dev.mysql.com/doc/refman/5.7/en/option-files.html
#The file must have three strings:

UserParameter=mysql.ping[*], /usr/local/mariadb/bin/mysqladmin -h"$1" -P"$2" ping

UserParameter=mysql.get_status_variables[*], /usr/local/mariadb/bin/mysql -h"$1" -P"$2" -u<Username> -p<Password> -sNX -e "show global status"

UserParameter=mysql.version[*], /usr/local/mariadb/bin/mysqladmin -s -h"$1" -P"$2" version

UserParameter=mysql.db.discovery[*], /usr/local/mariadb/bin/mysql -h"$1" -P"$2" -sN -u<Username> -p<Password> -e "show databases"

UserParameter=mysql.dbsize[*], /usr/local/mariadb/bin/mysql -h"$1" -P"$2" -u<Username> -p<Password> -sN -e "SELECT SUM(DATA_LENGTH + INDEX_LENGTH) FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA='$3'"

UserParameter=mysql.replication.discovery[*], /usr/local/mariadb/bin/mysql -h"$1" -P"$2" -u<Username> -p<Password> -sNX -e "show slave status"

UserParameter=mysql.slave_status[*], /usr/local/mariadb/bin/mysql -h"$1" -P"$2" -u<Username> -p<Password> -sNX -e "show slave status"

以及,由于访问数据库默认使用的localhost而不是我指定宏的127.0.0.1,因此建议新建用户时也将主机域设置为全局%
