环境：centos 6.5,mysql 5.6,zabbix 2.4.4
1、在mysql中添加zabbix用户
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
vim /usr/local/zabbix/etc/.my.cnf[mysql]host=127.0.0.1user=zabbixpassword=zabbixsocket=/tmp/mysql.sock[mysqladmin]host=127.0.0.1user=zabbixpassword=zabbixsocket=/tmp/mysql.sock3、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
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.confUserParameter=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 -NUserParameter=mysql.ping,HOME=/usr/local/zabbix/etc /usr/local/mysql/bin/mysqladmin ping | grep -c aliveUserParameter=mysql.version,/usr/local/mysql/bin/mysql -V4、修改agentd配置文件
vim /usr/local/zabbix/etc/zabbix_agentd.confLogFile=/tmp/zabbix_agentd.logServer=192.168.100.161ServerActive=192.168.100.161Hostname=Zabbix serverInclude=/usr/local/zabbix/etc/zabbix_agentd.conf.d/EnableRemoteCommands=1UnsafeUserParameters=15、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
zabbix_get -s 127.0.0.1 -p 10050 -k "mysql.version"
