zabbix 自带模板监控mysql_使用zabbix自带的模板监控MySQL自带

一、安装zabbix server 略

二、安装zabbix agent 略

三、给主机套自带的模板 略

四、创建授权用户

mysql> grant all on *.* to 'zabbix'@'localhost' identified by 'musingtec2019';

Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;

Query OK, 0 rows affected (0.00 sec)

mysql> quit

Bye

五、创建连接文件

root@[ 8.10.201.33 ]@znhjkdba:/etc/zabbix# ls

zabbix_agentd.conf  zabbix_agentd.d

root@[ 8.10.201.33 ]@znhjkdba:/etc/zabbix# cat .my.cnf

[mysql]

host=localhost

user=zabbix

password=musingtec2019

socket=/tmp/mysql.sock

[mysqladmin]

host=localhost

user=zabbix

password=musingtec2019

socket=/tmp/mysql.sock

六、修改模板文件

修改里面的路径为.my.cnf的路径

sed -i "s@/var/lib/zabbix@/etc/zabbix@g" /etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf

里面的路径如果找不到mysql  或者mysqladmin 请修改使用绝对路径。我用的就是绝对路径

root@[ 8.10.201.33 ]@znhjkdba:/etc/zabbix# cat 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=/etc/zabbix /data/mysql/bin/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 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=/etc/zabbix mysql -N'

UserParameter=mysql.ping,HOME=/etc/zabbix /data/mysql/bin/mysqladmin ping | grep -c alive

UserParameter=mysql.version,/data/mysql/bin/mysql -V

UserParameter=mysql.portNum,/usr/sbin/ss -an |grep :3306 |wc -l #这个是我自定义的

七、重启代理和测试

systemctl restart zabbix-agent

root@[zbx-srv1 8.11.8.168]@iimapp1:/root# zabbix_get -I 8.11.8.170 -s 8.10.201.33 -p 10050 -k "mysql.version"

/data/mysql/bin/mysql  Ver 14.14 Distrib 5.6.44, for linux-glibc2.12 (x86_64) using  EditLine wrapper

root@[zbx-srv1 8.11.8.168]@iimapp1:/root# zabbix_get -I 8.11.8.170 -s 8.10.201.33 -p 10050 -k "mysql.ping"

1

root@[zbx-srv1 8.11.8.168]@iimapp1:/root# zabbix_get -I 8.11.8.170 -s 8.10.201.33 -p 10050 -k "mysql.portNum"

124

root@[zbx-srv1 8.11.8.168]@iimapp1:/root#

八、查看服务端最新数据

九、创建触发器
