    zabbix 监控mysql实例

    环境:
    CentOS 7.2
    zabbix-3.0.5 LTS
    nginx-1.10.1
    php-7.0.11
    mariadb-10.1.18


    请参看


    监控mysql

    zabbix自带mysql模板监控mariadb,更全面的监控可以自行编写脚本或才通过第三方模板,如http://www.fromdual.com/mpm-installation-guide


    在要监控的mysql主机上

    1.安装zabbix客户端

    2.创建具有监控权限的数据库用户

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

    FLUSH PRIVILEGES;

    3.创建数据库连接配置文件

    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

    可根据环境不同作相应调整

    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进来

     

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

    5.重启zabbix_agentd

    /etc/init.d/zabbix_agentd restart

    6.测试

    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


    日志里也一直提示mysql命令not found

     61652:20160430:223023.549 item "Zabbix server:mysql.status[Bytes_received]" became not supported: Received value [sh: mysql: command not found] is not suitable for value type [Numeric (float)]

    但实际上mysql命令是存在的,只是非标准路径,mariadb安装在/opt/mariadb下,故mysql命令的绝对路径是/opt/mariadb/bin/mysql,但我己经在/etc/profile中作了全局申明,export PATH=/opt/mariadb/bin:$PATH,但还是报mysql  not found,于是百度了下,还真有朋友碰到相同的问题,试了下

    解决方案

    A./usr/local/zabbix/etc/zabbix_agentd.conf.d/userparameter_mysql.conf中的所有mysql,mysqladmin替换为绝对路径

    或者

    B.将mysql,mysqladmin软链到/usr/bin下

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

    注意:软链到/usr/local/bin下无效,只能呵呵了


    推荐B方案,软链后立马就生效了

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