  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:  [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 $1  查看mysql授权:  wKiom1i3or6yXIfoAAA3WVHaxd8949.png-wh_50  mysql授权需要密码才能访问,但是使用密码mysql会提示明文密码,就会有下面的提示:  [root@iZuf67iz9o3i4wixgtwybnZ alertscripts]# sh check_mysql_slave.sh  Warning: Using a password on the command line interface can be insecure.  ok -slave is running  解决办法如下:  [root@iZuf67iz9o3i4wixgtwybnZ alertscripts]# cat /etc/my.cnf | tail -4  [client]  user = root  host = localhost  password = 1qaz@WSX  再次运行脚本:  [root@iZuf67iz9o3i4wixgtwybnZ alertscripts]# sh check_mysql_slave.sh  ok -slave is running  mysql主从监控脚本,脚本中去掉用户,密码直接使用命令。  [root@iZuf67iz9o3i4wixgtwybnZ alertscripts]# cat check_mysql_slave.sh  #!/bin/bash  declare -a slave_is  slave_is=($(/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:  [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。  [root@iZuf67iz9o3i4wixgtwybmZ bin]# ./zabbix_get -s 10.18.3.191 -k mysql.status[Uptime]  ZBX_NOTSUPPORTED: Unsupported item key.  [root@iZuf67iz9o3i4wixgtwybmZ bin]# ./zabbix_get -s 10.18.3.191 -k mysql.status[Uptime]  /usr/local/zabbix/share/zabbix/alertscripts/mysql_server_status.sh: line 4: mysqladmin: command not found  [root@iZuf67iz9o3i4wixgtwybmZ bin]# ./zabbix_get -s 10.18.3.191 -k mysql.status[Uptime]  414242  zabbix_agent.log可以看到已经获取到自定义的key:  wKiom1i3ojuQLV_2AAEobxWRPDI852.png-wh_50  添加自定义模板,模板名称随意给个和mysql相关的:  wKioL1i3o-7ivVBFAABlolKDSbw675.png-wh_50  创建应用集:  wKioL1i3pDnjLB2JAAA9LYgzWFE576.png-wh_50  添加监控项,一个key一个key添加,把脚本的key都添加进去。  wKioL1i3pIrS6cCUAAB3jZDOFlw111.png-wh_50  如下所示:  wKiom1i3pFexNKMDAAGE4D0rHXA177.png-wh_50  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:  wKiom1i3pPrBu-umAADKdeUVUl4065.png-wh_50  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。  wKiom1i3pUGRlJQLAAEEu7d-8H8906.png-wh_50  查看图形监控数据:  wKiom1i3pXTy4qA1AAEtLjIBgME208.png-wh_50  参考文章:http://www.ttlsa.com/zabbix/zabbix-monitor-mysql/
