shell腳本操作mysql數據庫，使用mysql的-e參數可以執行各種sql的(創建，刪除，增，刪，改、查)等各種操作

mysql  -hhostname -Pport -uusername -ppassword  -e  相關mysql的sql語句，不用在mysql的提示符下運行mysql，即可以在shell中操作mysql的方法。

 

#!/bin/bash

HOSTNAME="192.168.111.84"                                           #數據庫信息
PORT="3306"
USERNAME="root"
PASSWORD=""

DBNAME="test_db_test"                                                       #數據庫名稱
TABLENAME="test_table_test"                                            #數據庫中表的名稱

 

#創建數據庫
create_db_sql="create database IF NOT EXISTS ${DBNAME}"
mysql -h${HOSTNAME}  -P${PORT}  -u${USERNAME} -p${PASSWORD} -e "${create_db_sql}"

 

#創建表
create_table_sql="create table IF NOT EXISTS ${TABLENAME} (  name varchar(20), id int(11) default 0 )"
mysql -h${HOSTNAME}  -P${PORT}  -u${USERNAME} -p${PASSWORD} ${DBNAME} -e "${create_table_sql}"

 

#插入數據
insert_sql="insert into ${TABLENAME} values('billchen',2)"
mysql -h${HOSTNAME}  -P${PORT}  -u${USERNAME} -p${PASSWORD} ${DBNAME} -e "${insert_sql}"

 

#查詢
select_sql="select * from ${TABLENAME}"
mysql -h${HOSTNAME}  -P${PORT}  -u${USERNAME} -p${PASSWORD} ${DBNAME} -e "${select_sql}"

 

#更新數據
update_sql="update ${TABLENAME} set id=3"
mysql -h${HOSTNAME}  -P${PORT}  -u${USERNAME} -p${PASSWORD} ${DBNAME} -e "${update_sql}"
mysql -h${HOSTNAME}  -P${PORT}  -u${USERNAME} -p${PASSWORD} ${DBNAME} -e "${select_sql}"

 

#刪除數據
delete_sql="delete from ${TABLENAME}"
mysql -h${HOSTNAME}  -P${PORT}  -u${USERNAME} -p${PASSWORD} ${DBNAME} -e "${delete_sql}"
mysql -h${HOSTNAME}  -P${PORT}  -u${USERNAME} -p${PASSWORD} ${DBNAME} -e "${select_sql}"

 

show processlist如何過濾的問題我終於知道如何解決了

mysql -uroot -e  -p password  'show processlist\G';

mysql -uroot -e 'show processlist\G'|grep 'Info'|grep -v "NULL"|awk -F ":" '{print $2}'|sort|uniq -c|sort -rn;(查看正在執行的語句有哪些,並做好歸並排序:)
