原本想用python腳本監控一下mysql的，沒有找到相關資料，懶得折騰了，使用官方自帶的監控模板進行監控mysql

添加zabbix-agent配置文件

把默認的userparameter_mysql.conf 文件進行替換爲一下內容
[root@test-mq01 zabbix_agentd.d]# cat userparameter_mysql.conf

#UserParameter=mysql.status[*],echo "show global status where Variable_name='$1';" | HOME=/var/lib/zabbix mysql -N | awk '{print $$2}' UserParameter=mysql.status[*],/etc/zabbix/script/mysql/chk_mysql.sh $1 #UserParameter=mysql.size[*],bash -c 'echo "select sum($(case "$3" in both|"") echo "data_length+index_length";; data|index) echo "$3_length";; free) echo "data_free";; esac)) from information_schema.tables$([[ "$1" = "all" || ! "$1" ]] || echo " where table_schema=\"$1\"")$([[ "$2" = "all" || ! "$2" ]] || echo "and table_name=\"$2\"");" | HOME=/var/lib/zabbix mysql -N' #UserParameter=mysql.ping,HOME=/var/lib/zabbix mysqladmin ping | grep -c alive UserParameter=mysql.ping,mysqladmin -u root -pRoo -P3306 -h192.168.2.252 ping | grep -c alive UserParameter=mysql.version,mysql -V

添加chk_mysql.sh腳本文件

/etc/zabbix/script/mysql/chk_mysql.sh

#!/bin/bash # ------------------------------------------------------------------------------- # FileName: check_mysql.sh # Revision: 1.0 # Date: 2018/01/31 # Author: chunk # Email:  # Website:  # Description:  # Notes: ~ # ------------------------------------------------------------------------------- # Copyright:  # License: GPL # 用戶名 MYSQL_USER='root' # 密碼 MYSQL_PWD='Root' # 主機地址/IP MYSQL_HOST='192.168.2.252' # 端口 MYSQL_PORT='3306' # 數據鏈接 MYSQL_CONN="/usr/bin/mysqladmin -u${MYSQL_USER} -p${MYSQL_PWD} -h${MYSQL_HOST} -P${MYSQL_PORT}" # 參數是否正確 if [ $# -ne "1" ];then echo "arg error!" fi # 獲取數據 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-web端主機添加模板連接

添加被監控服務的 mysql賬號：

GRANT PROCESS,SUPER,REPLICATION CLIENT ON *.* TO zabbix@'127.0.0.1' IDENTIFIED BY '123456';

• 1

添加check腳本權限：

chmod 755 /etc/zabbix/chk_mysql.sh

• 1
• 2
• 3

去zabbix服務器上面檢查基本mysql服務器信息是否能正常獲取到，zabbix_get -s 10.0.1.30 -p10050 -k」system.cpu.load[all,avg15]」;：

[root@hch_test_121_12 html]# zabbix_get -s 10.0.1.30 -p10050 -k "system.cpu.load[all,avg15]";

[root@hch_test_121_12 html]#

重啓監控端agent

service zabbix-agent restart

zabbix server端測試是否有數據

[root@tools-jenkins ~]# zabbix_get -s 192.168.2.41 -k mysql.status[Questions] 3533479678

[Warning] Using a password on the command line interface can be insecure.

這個其實很簡單，腳本中導入export MYSQL_PWD=<password>，或者/etc/bashrc導入export MYSQL_PWD=<password>
最後腳本少-p，大概格式是這樣：

#原數據鏈接 # 數據鏈接 MYSQL_CONN="/usr/bin/mysqladmin -u${MYSQL_USER} -p${MYSQL_PWD} -h${MYSQL_HOST} -P${MYSQL_PORT}" # 新數據鏈接 MYSQL_CONN="/usr/bin/mysqladmin -u${MYSQL_USER} -h${MYSQL_HOST} -P${MYSQL_PORT}"
