shell脚本中执行mysql 语句,去除warning using a password on the command line interface can be insecure信息

方法二：使用mysql参数的方法

当然，可以通过将传参的方式来传递 -e 后面的语句。

使用示例：

cat count_tb_post_fourhour.sh
#!/bin/bash

count_tb_post_fourhour_keys=`/usr/bin/mysql -hrr-bp1************3.mysql.rds.aliyuncs.com -uzh*****ng -p********  -D dee****hion -e "select count(1) from tb_post where created_at > date_sub(now(), interval 4 hour) and platformId = 1;" 2>&1 |grep -v "Warning: Using a password"|grep -v "count";`

echo $count_tb_post_fourhour_keys


[root@weifeng scripts]# sh count_tb_post_fourhour.sh
