通过shell脚本进行数据库操作

 #!/bin/bash

 HOSTNAME="192.168.111.84"  #数据库信息

 PORT=""

 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), id int(11) default 0 )"

 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 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}"

 #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}"

#也可以写 HOSTNAME="localhost"，端口号 PORT可以不设定

例：

 #!/bin/bash
 HOSTNAME="localhost"  #数据库信息
 PORT=""
 USERNAME="app_shhengyin_c"
 PASSWORD="87JXiSJ"
 DBNAME="app_shhengyin_c"  #数据库名称
 TABLENAME="wx_user" #数据库中表的名称
 #更新数据,更新抽奖次数为1
 update_sql="update ${TABLENAME} set score=1"
 mysql -h${HOSTNAME} -P${PORT} -u${USERNAME} -p${PASSWORD} ${DBNAME} -e "${update_sql}"
 #更新数据,更新分享数为0
 update_sql="update ${TABLENAME} set sharnum=0"
 mysql -h${HOSTNAME} -P${PORT} -u${USERNAME} -p${PASSWORD} ${DBNAME} -e "${update_sql}"
