mysql 5.7.11 zip安装配置方法图文教程
一、下载mysql 5.7.11 zip 安装包
本机以win7 64位系统为例,如果是32位系统,请下载32位的安装包
选择 windows (x86, 64-bit), zip archive 下载包
二、解压安装包 | extracting the install archive
d:\victor.min\software\mysql-5.7.11-winx64 #我的解压目录
三、创建一个空文件夹,命名为data, 也可以随便命名,用来存放数据
# 本机创建在 d:\victor.min\software\mysql-5.7.11-winx64 目录下,所以最后会看到 d:\victor.min\software\mysql-5.7.11-winx64\data #此文件夹后面会有用到
四、配置一个自己的启动配置文件 | creating an option file
如果自己用没什么特别的,就把 d:\victor.min\software\mysql-5.7.11-winx64\my-default.ini 文件copy一份,重新命名为 my.ini ,修改里面的几个参数就好了 || 配置文件如下
# 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 为安装文件解压后的目录 | basedir和datadir 可以使用相对路径 # basedir=./.. basedir=d:\\victor.min\\software\\mysql-5.7.11-winx64 # datadir 为用来存放数据的目录 # datadir=./../data datadir=d:\\victor.min\\software\\mysql-5.7.11-winx64\\data # port 为端口号 port=3306 # mar_connections为最大连接数 max_connections=20 character_set_server=utf8 # 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 explicit_defaults_for_timestamp=true sql_mode=no_engine_substitution,strict_trans_tables
五、初始化数据目录 initializing the data directory
当然,按照mysql官方文档给出的步骤还有一步 selecting a mysql server type,就是选择用 mysqld 还是 mysqld-debug |命令如下
mysqld --defaults-file="d:\victor.min\software\mysql-5.7.11-winx64\my.ini" --initialize-insecure
注:
1、这个命令很重要,它会初始化 data 目录,在执行此命令前请先把data目录下的所有文件先删除,否则会失败
2、可以选择用 --initialize-insecure 或者 --initialize 来初始化,--initialize-insecure 初始化root密码为空,如果用 --initialize来初始化,会产生一个随机密码
执行成功后你会在data目录 下看到 mysql,perofrmance_schema,sys目录,同时还会有一些文件
六、安装 mysql 服务
mysqld -install
七、启动 mysql 服务
net start mysql
到这里,mysql服务就启动好,我们就可以用root进入 mysql
mysql -u root -p
为了方便,最好将mysql配置到环境变量中去
后记:
如果中途有什么步骤失败,一定要执行 mysql 移除命令,然后删除 data 目录下的所有文件
mysqld -remove
特别提醒:5.7 和 5.6 不太相同,要自己初始化数据 data 目录,不然启动不会成功
mysql 安装完后可能会用到的语句
alter user 'root'@'localhost' identified by '123'; create database victor; create user 'victor'@'localhost' identified by 'victor@123'; flush privileges; creaet user 'victorremote'@'%' identified by 'victorremote@123'; flush privileges; grant all on victor.* to 'victor'@'localhost' identified by 'victor@123'; flush privileges; grant all on victor.* to 'victorremote'@'%' identified by 'victorremote@123'; flush privileges; ################################
show variables like 'collation_%';
show variables like 'character_set_%';
set collation_connection=utf8_general_ci;
set character_set_client=utf8;
set character_set_connection=utf8;
set character_set_results=utf8;
