环境是Centos6.5 x86_64系统
Zabbix版本:3.0.4
Mysql Server 版本:5.6.29 二进制安装
zabbix_agentd.conf的配置文件如下:
1 2 3 4 5 6 7 8 9 10 11 12 13 | [root@iZuf67iz9o3i4wixgtwybnZ alertscripts] # cat /usr/local/zabbix/etc/zabbix_agentd.conf | grep -v '^#' | grep -v '^$' LogFile= /tmp/zabbix_agentd .log EnableRemoteCommands=1 Server=10.18.3.193 ListenPort=10050 ServerActive=10.18.3.193 Hostname=10.18.3.191 AllowRoot=1 Include= /usr/local/zabbix/etc/zabbix_agentd .conf.d/*.conf UnsafeUserParameters=1 #下面两行是自定义的key UserParameter=mysql.slave, /usr/local/zabbix/share/zabbix/alertscripts/check_mysql_slave .sh | grep -c 'ok' UserParameter=mysql.status[*], /usr/local/zabbix/share/zabbix/alertscripts/mysql_server_status .sh $1 |
查看mysql授权:
mysql授权需要密码才能访问,但是使用密码mysql会提示明文密码,就会有下面的提示:
1 2 3 | [root@iZuf67iz9o3i4wixgtwybnZ alertscripts] # sh check_mysql_slave.sh Warning: Using a password on the command line interface can be insecure. ok -slave is running |
解决办法如下:
1 2 3 4 5 | [root@iZuf67iz9o3i4wixgtwybnZ alertscripts] # cat /etc/my.cnf | tail -4 [client] user = root host = localhost password = 1qaz@WSX |
再次运行脚本:
1 2 | [root@iZuf67iz9o3i4wixgtwybnZ alertscripts] # sh check_mysql_slave.sh ok -slave is running |
mysql主从监控脚本,脚本中去掉用户,密码直接使用命令。
1 2 3 4 5 6 7 8 9 10 11 | [root@iZuf67iz9o3i4wixgtwybnZ alertscripts] # cat check_mysql_slave.sh #!/bin/bash declare -a slave_is slave_is=($( /data/mysql/bin/mysql -e "show slave status\G" | grep -E "Slave_IO_Running|Slave_SQL_Running:" | awk '{print $2}' )) if [ "${slave_is[0]}" = "Yes" -a "${slave_is[1]}" = "Yes" ]; then echo "ok -slave is running" exit 0 else echo "down -slave is not running" exit 2 fi |
mysql_server_status脚本,这块上面my.cnf填写以后,使用mysqladmin也就不提示了:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 | [root@iZuf67iz9o3i4wixgtwybnZ alertscripts] # cat mysql_server_status.sh #!/bin/bash source /etc/profile mysqladmin=` which mysqladmin` case $1 in Uptime) result=`${mysqladmin} status| cut -f2 -d ":" | cut -f1 -d "T" ` echo $result ;; Com_update) result=`${mysqladmin} extended-status | grep -w "Com_update" | cut -d "|" -f3` echo $result ;; Slow_queries) result=`${mysqladmin} status | cut -f5 -d ":" | cut -f1 -d "O" ` echo $result ;; Com_select) result=`${mysqladmin} extended-status | grep -w "Com_select" | cut -d "|" -f3` echo $result ;; Com_rollback) result=`${mysqladmin} extended-status | grep -w "Com_rollback" | cut -d "|" -f3` echo $result ;; Questions) result=`${mysqladmin} status| cut -f4 -d ":" | cut -f1 -d "S" ` echo $result ;; Com_insert) result=`${mysqladmin} extended-status | grep -w "Com_insert" | cut -d "|" -f3` echo $result ;; Com_delete) result=`${mysqladmin} extended-status | grep -w "Com_delete" | cut -d "|" -f3` echo $result ;; Com_commit) result=`${mysqladmin} extended-status | grep -w "Com_commit" | cut -d "|" -f3` echo $result ;; Bytes_sent) result=`${mysqladmin} extended-status | grep -w "Bytes_sent" | cut -d "|" -f3` echo $result ;; Bytes_received) result=`${mysqladmin} extended-status | grep -w "Bytes_received" | cut -d "|" -f3` echo $result ;; Com_begin) result=`${mysqladmin} extended-status | grep -w "Com_begin" | cut -d "|" -f3` echo $result ;; *) echo "Usage:$0(Uptime|Com_update|Slow_queries|Com_select|Com_rollback|Questions|Com_insert|Com_delete|Com_commit|Bytes_sent|Bytes_received|Com_begin)" ;; esac |
在zabbix_server获取key值,或是查看zabbix_server.log文件都可以排错。

zabbix_agent.log可以看到已经获取到自定义的key:
添加自定义模板,模板名称随意给个和mysql相关的:
创建应用集:
添加监控项,一个key一个key添加,把脚本的key都添加进去。
如下所示:
mysql 状态这块只做了图形查看,并没有做触发器,只做了主从的触发器,需要的可以自己添加:
添加完成后可以添加一台mysql数据库查看下最新数据,是否成功了。
查看图形监控数据:
