Zabbix4.2监控MySQL5.7

一、修改zabbix agent配置文件

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

1、修改第1处

第1处修改前:

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

第1处修改后:

UserParameter=mysql.status[*],echo "show global status where Variable_name='$1';" | HOME=/var/lib/zabbix mysql -h 127.0.0.1 -uroot -pabcABC-123 -N 2>/dev/null | awk '{print $$2}'

标黄部分为第1处修改的内容:
UserParameter=mysql.status[*],echo “show global status where Variable_name=’$1’;” | HOME=/var/lib/zabbix mysql -h 127.0.0.1 -uroot -pabcABC-123 -N 2>/dev/null | awk ‘{print $$2}’

2>/dev/null”的作用是防止MySQL5.6以上版本报以下错误:

 mysql: [Warning] Using a password on the command line interface can be insecure.

2、修改第2处

第2处修改前:

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

第2处修改后:

UserParameter=mysql.ping,HOME=/var/lib/zabbix mysqladmin ping -h 127.0.0.1 -uroot -pabcABC-123 2>/dev/null | grep -c alive

标黄部分为第2处修改的内容:
UserParameter=mysql.ping,HOME=/var/lib/zabbix mysqladmin ping -h 127.0.0.1 -uroot -pabcABC-123 2>/dev/null | grep -c alive

三、重启zabbix agent服务

systemctl restart zabbix-agent

四、修改后的完整文件:

# 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 -h 127.0.0.1 -uroot -pabcABC-123 -N 2>/dev/null | 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 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 -h 127.0.0.1 -uroot -pabcABC-123 2>/dev/null | grep -c alive
UserParameter=mysql.version,mysql -V
