使用zabbix 2.4 监控mysql

231w

环境：centos 6.5,mysql 5.6,zabbix 2.4.4
1、在mysql中添加zabbix用户

1 2 3

mysql -uroot -p -e "GRANT USAGE ON *.* TO 'zabbix'@'127.0.0.1' IDENTIFIED BY 'zabbix'"; mysql -uroot -p -e "GRANT USAGE ON *.* TO 'zabbix'@'localhost' IDENTIFIED BY 'zabbix'"; mysql -uroot -p -e"flush privileges"

2、新建.my.cnf文件

1 2 3 4 5 6 7 8 9 10 11

vim /usr/local/zabbix/etc/.my.cnf [mysql] host=127.0.0.1 user=zabbix password=zabbix socket=/tmp/mysql.sock [mysqladmin] host=127.0.0.1 user=zabbix password=zabbix socket=/tmp/mysql.sock

3、复制并修改mysql的key值文件，将HOME指定到.my.cnf文件所在文件的路径，mysql和mysqladmin命令使用绝对路径

1 2 3 4 5 6

cp /root/zabbix-2.4.5/conf/zabbix_agentd/userparameter_mysql.conf /usr/local/zabbix/etc/zabbix_agentd.conf.d/ vim /usr/local/zabbix/etc/zabbix_agentd.conf.d/userparameter_mysql.conf UserParameter=mysql.status ,echo "show global status where Variable_name='$1';" | HOME=/usr/local/zabbix/etc /usr/local/mysql/bin/mysql -N | awk '{print $$2}' UserParameter=mysql.size ,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=/usr/local/zabbix/etc /usr/local/mysql/bin/mysql -N UserParameter=mysql.ping,HOME=/usr/local/zabbix/etc /usr/local/mysql/bin/mysqladmin ping | grep -c alive UserParameter=mysql.version,/usr/local/mysql/bin/mysql -V

4、修改agentd配置文件

1 2 3 4 5 6 7 8

vim /usr/local/zabbix/etc/zabbix_agentd.conf LogFile=/tmp/zabbix_agentd.log Server=192.168.100.161 ServerActive=192.168.100.161 Hostname=Zabbix server Include=/usr/local/zabbix/etc/zabbix_agentd.conf.d/ EnableRemoteCommands=1 UnsafeUserParameters=1

5、使用zabbix_get获取key值，zabbix_get在zabbix server上使用有返回值，在zabbix agent使用无返回值，要查看agent的key值，可以把127.0.0.1改为agent的ip

1	zabbix_get -s 127.0.0.1 -p 10050 -k "mysql.version"
