原本想用python脚本监控一下mysql的，没有找到相关资料，懒得折腾了，使用官方自带的监控模板进行监控mysql

添加zabbix-agent配置文件

把默认的userparameter_mysql.conf 文件进行替换为一下内容
[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脚本文件

/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 # 用户名 MYSQL_USER='root' # 密码 MYSQL_PWD='Root' # 主机地址/IP MYSQL_HOST='192.168.2.252' # 端口 MYSQL_PORT='3306' # 数据链接 MYSQL_CONN="/usr/bin/mysqladmin -u${MYSQL_USER} -p${MYSQL_PWD} -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-web端主机添加模板连接

添加被监控服务的 mysql账号：

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

• 1

添加check脚本权限：

chmod 755 /etc/zabbix/chk_mysql.sh

• 1
• 2
• 3

去zabbix服务器上面检查基本mysql服务器信息是否能正常获取到，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]";                                                                 

0.050000

[root@hch_test_121_12 html]#

重启监控端agent

service zabbix-agent restart

zabbix server端测试是否有数据

[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.

这个其实很简单，脚本中导入export MYSQL_PWD=<password>，或者/etc/bashrc导入export MYSQL_PWD=<password>
最后脚本少-p，大概格式是这样：

#原数据链接 # 数据链接 MYSQL_CONN="/usr/bin/mysqladmin -u${MYSQL_USER} -p${MYSQL_PWD} -h${MYSQL_HOST} -P${MYSQL_PORT}" # 新数据链接 MYSQL_CONN="/usr/bin/mysqladmin -u${MYSQL_USER} -h${MYSQL_HOST} -P${MYSQL_PORT}"
