zabbix有內建的mysql監控模板，所以對mysql監控時可以不用新建*.conf檔案。

1.在agent端檢視預設配置檔案----userparameter_mysql.conf ，原文配置如下。

cat /etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf 


# For all the following commands HOME should be set to the directory that has .my.cnf file with password information.

# Flexible parameter to grab global variables. On the frontend side, use keys like mysql.status[Com_insert].
# Key syntax is mysql.status[variable].

UserParameter=mysql.status[*],echo "show global status where Variable_name='$1';" | HOME=/var/lib/zabbix mysql -N | awk '{print $$2}'

# Flexible parameter to determine database or table size. On the frontend side, use keys like mysql.size[zabbix,history,data].
# Key syntax is mysql.size[<database>,<table>,<type>].
# Database may be a database name or "all". Default is "all".
# Table may be a table name or "all". Default is "all".
# Type may be "data", "index", "free" or "both". Both is a sum of data and index. Default is "both".
# Database is mandatory if a table is specified. Type may be specified always.
# Returns value in bytes.
# 'sum' on data_length or index_length alone needed when we are getting this information for whole database instead of a single table
UserParameter=mysql.size[*],bash -c 'echo "select sum($(case "$3" in both|"") echo "data_length+index_length";; data|index) echo "$3_length";; free) echo "data_free";; esac)) from information_schema.tables$([[ "$1" = "all" || ! "$1" ]] || echo " where table_schema=\"$1\"")$([[ "$2" = "all" || ! "$2" ]] || echo "and table_name=\"$2\"");" | HOME=/var/lib/zabbix mysql -N'

UserParameter=mysql.ping,HOME=/var/lib/zabbix mysqladmin ping | grep -c alive
UserParameter=mysql.version,mysql -V
 

2.新建檔案路徑

通過檢視配置檔案，知道zabbix中mysql的鍵值是-mysql.status[*],存放的路徑是/var/lib/zabbix。var下的zabbix資料夾和檔案需要自己新建並填入mysql的使用者、密碼。

#新建資料夾/檔案
mkdir /var/lib/zabbix

vim /var/lib/zabbix/.my.cnf

#填入內容
[mysql]
user=zabbix
password=zabbix
host=127.0.0.1

[mysqladmin]
user=zabbix
password=zabbix
host=127.0.0.1

3.重啟mysql，zabbix-agent服務。

4.配置zabbix-server端

zabbix端的頁面中，本身就已經配置好了模板，只需要關聯上主機即可。不同的版本可能模板名稱不一樣，例如DBmysql和Template APP MySQL。

 5.檢視

在監測中->圖形下，可以檢視mysql的監控圖形,Mysql bandwith 和Mysql operation。
