shell脚本导出mysql数据

如何实时查看数据信息呢，方式多的去了，但是还是脚本最为方便。

脚本导出到文件中demo示例

新建export.sh

#!/bin/bash
# 用户名
MYSQL_USER=root
# 密码
MYSQL_PWD=123456
# 库名
MYSQL_NAME=center
# 主机
MYSQL_HOST=172.0.0.1
# 端口号
MYSQL_PORT=3306

mysql -u${MYSQL_USER} -p${MYSQL_PWD} -P${MYSQL_PORT} -h${MYSQL_HOST} -D${MYSQL_NAME} << EOF > $2
set character_set_client = utf8;     
set character_set_results = utf8;    
set character_set_connection = utf8; 
$1
EOF

执行脚本

$! $2 就是命令后面加的参数
sh export.sh 'select id,name from sport;' './export.txt'

新建dingding.sh

#!/bin/bash
MYSQL_USER=root
MYSQL_PWD=123456
MYSQL_NAME=center
MYSQL_HOST=172.0.0.1
MYSQL_PORT=3306

SQL_DATA=`mysql -u${MYSQL_USER} -p${MYSQL_PWD} -P${MYSQL_PORT} -h${MYSQL_HOST} -D${MYSQL_NAME} << EOF
set character_set_client = utf8;     
set character_set_results = utf8;    
set character_set_connection = utf8;
select id,name from sport;
EOF`

echo $SQL_DATA

DATA="$(date +'%Y-%m-%d %T') 
$SQL_DATA"

MSG='{"msgtype": "text", 
        "text": {
             "content": "hello world chy

'$DATA'"
        }
      }'
echo $MSG

curl 'https://oapi.dingtalk.com/robot/send?access_token=abc' \
   -H 'Content-Type: application/json' \
   -d "$MSG

配合linux的定时任务

crontab -e编辑新增(linux最小单位是分钟，如下表示1分钟执行一次)
*/1 * * * * sh /usr/local/shell/dingding.sh

perfect!!!
