本来想用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
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 -h292.168.2.252 ping | grep -c alive
UserParameter=mysql.version,mysql -V
/etc/zabbix/script/mysql/chk_mysql.sh

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