Linux shell腳本010（mysql操作腳本）

#!/bin/bash
host="localhost"
user="root"
passwd="Wck12345"
db="testdb"
table="test"
log="/root/test/log_sql"
sql_create_db="create database IF NOT EXISTS ${db}"
sql_create_table="create table IF NOT EXISTS ${table} (id varchar(10),name varchar(50),sex varchar(10),age varchar(10))"
sql_insert="insert into ${table} values ('2','Mary','woman','19'),('3','Tony','man','19')"
sql_select="select * from ${table}"
mysql -h${host} -u${user} -p${passwd} -e "${sql_create_db}" -vvv >> ${log}
mysql -h${host} -u${user} -p${passwd} ${db} -e "${sql_create_table}" -vvv >> ${log}
mysql -h${host} -u${user} -p${passwd} ${db} -e "${sql_insert}" -vvv >> ${log}
mysql -h${host} -u${user} -p${passwd} ${db} -e "${sql_select}" -vvv >> ${log}
mysqldump --opt -h${host} -u${user} -p${passwd} ${db} > /root/test/db_`date +%F`.sql

恢復數據庫語句

mysql -h${host} -u${user} -p${passwd} ${db} < /root/test/db_`date +%F`.sql

知識點：
mysql -e用法，mysqldump用法，mysql -v用法，數據庫備份與恢復
shell腳本操作數據庫
