shell脚本操作mysql数据库 （部份参考）
mysql-hhostname -Pport -uusername -ppassword-e相关mysql的sql语句，不用在mysql的提示符下运行mysql，即可以在shell中操作mysql的方法。#!/bin/bash
HOSTNAME="192.168.111.84" #数据库信息
PORT="3306"
USERNAME="root"
PASSWORD=""
DBNAME="test_db_test" #数据库名称
TABLENAME="test_table_test" #数据库中表的名称
#创建数据库
create_db_sql="create database IF NOT EXISTS ${DBNAME}"
mysql -h${HOSTNAME}-P${PORT}-u${USERNAME} -p${PASSWORD} -e"${create_db_sql}"
#创建表
create_table_sql="create table IF NOT EXISTS ${TABLENAME} (name varchar(20),> mysql -h${HOSTNAME}-P${PORT}-u${USERNAME} -p${PASSWORD} ${DBNAME} -e "${create_table_sql}"
#插入数据
insert_sql="insert into ${TABLENAME} values('billchen',2)"
mysql -h${HOSTNAME}-P${PORT}-u${USERNAME} -p${PASSWORD} ${DBNAME} -e "${insert_sql}"
#查询
select_sql="select * from ${TABLENAME}"
mysql -h${HOSTNAME}-P${PORT}-u${USERNAME} -p${PASSWORD} ${DBNAME} -e "${select_sql}"
#更新数据
update_sql="update ${TABLENAME} set> mysql -h${HOSTNAME}-P${PORT}-u${USERNAME} -p${PASSWORD} ${DBNAME} -e "${update_sql}"
mysql -h${HOSTNAME}-P${PORT}-u${USERNAME} -p${PASSWORD} ${DBNAME} -e "${select_sql}"
#删除数据
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}"
