zabbix 監控mysql實例

環境:

CentOS 7.2

zabbix-3.0.5 LTS

nginx-1.10.1

php-7.0.11

mariadb-10.1.18

監控mysql

zabbix自帶mysql模板監控mariadb,更全面的監控能夠自行編寫腳本或才經過第三方模板，如http://www.fromdual.com/mpm-installation-guide

在要監控的mysql主機上

1.安裝zabbix客戶端

2.建立具備監控權限的數據庫用戶

GRANT USAGE ON *.* TO 'zabbix'@'localhost' IDENTIFIED BY 'zabbix';

FLUSH PRIVILEGES;

3.建立數據庫鏈接配置文件

root@jlive:~#cat >/usr/local/zabbix/etc/.my.cnf <<HERE

[mysql]

host     = localhost

user     = zabbix

password = zabbix

socket   = /tmp/mysql.sock

[mysqladmin]

host     = localhost

user     = zabbix

password = zabbix

socket   = /tmp/mysql.sock

HERE

可根據環境不一樣做相應調整

4.使用zabbix mysql模板配置文件userparameter_mysql.conf

cp /usr/local/src/zabbix-3.0.2/conf/zabbix_agentd/userparameter_mysql.conf /usr/local/zabbix/etc/zabbix_agentd.conf.d

sed -i 's#/var/lib/zabbix#/usr/local/zabbix/etc#g' /usr/local/zabbix/etc/zabbix_agentd.conf.d/userparameter_mysql.conf 

在agentd主配置文件中Include進來

 

sed -i '$ a Include=/usr/local/zabbix/etc/zabbix_agentd.conf.d' /usr/local/zabbix/etc/zabbix_agentd.conf

5.重啓zabbix_agentd

/etc/init.d/zabbix_agentd restart

6.測試

root@jlive:~#zabbix_agentd -c /usr/local/zabbix/etc/zabbix_agentd.conf -t mysql.status[uptime]

mysql.status[uptime]                          [t|11914]

root@jlive:~#zabbix_get -s localhost -p 10050 -k 'mysql.status[Bytes_received]'

sh: mysql: command not found

日誌裏也一直提示mysql命令not found

但實際上mysql命令是存在的，只是非標準路徑，mariadb安裝在/opt/mariadb下，故mysql命令的絕對路徑是/opt/mariadb/bin/mysql，但我己經在/etc/profile中做了全局申明，export PATH=/opt/mariadb/bin:$PATH，但仍是報mysql  not found，因而百度了下，還真有朋友碰到相同的問題，試了下

解決方案

A./usr/local/zabbix/etc/zabbix_agentd.conf.d/userparameter_mysql.conf中的全部mysql,mysqladmin替換爲絕對路徑

或者

B.將mysql,mysqladmin軟鏈到/usr/bin下

ln -s /opt/mariadb/bin/{mysql,mysqladmin} /usr/bin

注意:軟鏈到/usr/local/bin下無效，只能呵呵了

推薦B方案，軟鏈後立馬就生效了

root@jlive:~#zabbix_get -s localhost -p 10050 -k 'mysql.status[Bytes_received]'
