mysql学习之旅-数据库自动备份-测试环境搭建

Posted 2020-08-05 Yunier

#终于知道什么叫不会走先会跑了，刚开始接触第一个case就是数据库自动备份，我可是都没安装过啊？！   发完牢骚开始干活

首先，因为业务已经上线，不能随便动，先搭建测试环境吧

规划一下

版本：mysql-5.7.14-winx64.zip  从官网下载

系统：windows 7   64bit

解压缩到本地目录 D:\\app\\mysql57    #注意，非系统盘，非中文

将my-default.ini 复制一份重命名为my.ini  添加如下内容，先保证能开启服务

# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
# *** DO NOT EDIT THIS FILE. It\'s a template which will be copied to the
# *** default location during install, and will be replaced if you
# *** upgrade to a newer version of MySQL.

[mysqld]

# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
 innodb_buffer_pool_size = 128M

# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin

# These are commonly set, remove the # and set as required.
# basedir = .....
# datadir = .....
# port = .....
# server_id = .....
 basedir="D:\\app\\mysql57"
 datadir="D:\\app\\mysql57\\data"
port=3306
max_connections=200
character-set-server=utf8
default-storage-engine=INNODB

# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M 

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

修改环境变量path，增加bin目录


在命令行中cd到bin， 输入mysqld -install MySQL --defaults-file="D:\\app\\mysql57\\my.ini" 添加服务


在命令行中输入初始化命令 .\\mysqld.exe --initialize  会生成data目录，并且生成初始的root密码 ，否则net start mysql 会无法开启服务 #新版本特殊要求


之后服务可以开启，从后缀为err的文件中取得密码


复制默认密码，使用默认密码登录mysql


必须使用命令先修改密码，否则啥也不让干


mysql> alter user \'root\'@\'localhost\' identified by \'redhat\';
Query OK, 0 rows affected (0.00 sec)
密码修改成功，可以查询数据库了


安装完成
