由于MySQL5.7版本以上在命令行中不允许使用明文密码,所以需要将用户名和密码存在文件中:
认证信息文件内容如下:
[client] user=zabbix password="shengyan777.com"
监控MySQL的shell脚本内容如下:
#!/bin/bash # ------------------------------------------------------------------------------- # FileName: check_mysql.sh # Revision: 1.0 # 主机地址/IP MYSQL_HOST='127.0.0.1' # 端口 MYSQL_PORT='3306' # 数据连接 MYSQL_CONN="/usr/bin/mysqladmin --defaults-file=/etc/zabbix/scripts/mysqluser -h${MYSQL_HOST} -P${MYSQL_PORT}" # 参数是否正确 if [ $# -ne "1" ];then echo "arg error!" fi # 获取数据 case $1 in Uptime) result=`${MYSQL_CONN} status|cut -f2 -d":"|cut -f1 -d"T"` echo $result ;; Com_update) result=`${MYSQL_CONN} extended-status |grep -w "Com_update"|cut -d"|" -f3` echo $result ;; Slow_queries) result=`${MYSQL_CONN} status |cut -f5 -d":"|cut -f1 -d"O"` echo $result ;; Com_select) result=`${MYSQL_CONN} extended-status |grep -w "Com_select"|cut -d"|" -f3` echo $result ;; Com_rollback) result=`${MYSQL_CONN} extended-status |grep -w "Com_rollback"|cut -d"|" -f3` echo $result ;; Questions) result=`${MYSQL_CONN} status|cut -f4 -d":"|cut -f1 -d"S"` echo $result ;; Com_insert) result=`${MYSQL_CONN} extended-status |grep -w "Com_insert"|cut -d"|" -f3` echo $result ;; Com_delete) result=`${MYSQL_CONN} extended-status |grep -w "Com_delete"|cut -d"|" -f3` echo $result ;; Com_commit) result=`${MYSQL_CONN} extended-status |grep -w "Com_commit"|cut -d"|" -f3` echo $result ;; Bytes_sent) result=`${MYSQL_CONN} extended-status |grep -w "Bytes_sent" |cut -d"|" -f3` echo $result ;; Bytes_received) result=`${MYSQL_CONN} extended-status |grep -w "Bytes_received" |cut -d"|" -f3` echo $result ;; Com_begin) result=`${MYSQL_CONN} 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客户端的配置文件中添加以下内容:
[root@120 ~]# vim /etc/zabbix/zabbix_agentd.conf UserParameter=mysql.version,mysql -V UserParameter=mysql.status[*],/etc/zabbix/scripts/mysql-replication.sh $1 UserParameter=mysql.ping,sudo netstat -tnlp|egrep -i "mysql"|awk {'print $4'}|awk -F':' '{if ($NF~/^[0-9]*$/) print $NF}'|wc -l
登陆zabbix,点击Configuration –> Hosts,编辑监控主机,将Template App MySQL模板链接到监控主机的Templates中
到此,MySQL的监控就配置完成了。点击Monitoring –> Graphs ,选择mysql,过几分钟就能出图了
