1、下载mysql绿色版压缩包
https://dev.mysql.com/downloads/mysql/
2、解压到安装目录后,在根目录创建data文件夹
3、把mysql下的bin目录添加到环境变量
4、根目录创建my.ini文件,并拷贝以下代码,并修改basedir和datadir路径
# MySQL Server Instance Configuration File # ---------------------------------------------------------------------- # Generated by the MySQL Server Instance Configuration Wizard # # # Installation Instructions # ---------------------------------------------------------------------- # # On Linux you can copy this file to /etc/my.cnf to set global options, # mysql-data-dir/my.cnf to set server-specific options # (@localstatedir@ for this installation) or to # ~/.my.cnf to set user-specific options. # # On Windows you should keep this file in the installation directory # of your server (e.g. C:\\Program Files\\MySQL\\MySQL Server X.Y). To # make sure the server reads the config file use the startup option # "--defaults-file". # # To run run the server from the command line, execute this in a # command line shell, e.g. # mysqld --defaults-file="D:\\GreenSoft\\MySQL\\my.ini" # # To install the server as a Windows service manually, execute this in a # command line shell, e.g. # mysqld --install mysql --defaults-file="D:\\GreenSoft\\MySQL\\my.ini" # # And then execute this in a command line shell to start the server, e.g. # net start mysql # # # Guildlines for editing this file # ---------------------------------------------------------------------- # # In this file, you can use all long options that the program supports. # If you want to know the options a program supports, start the program # with the "--help" option. # # More detailed information about the individual options can also be # found in the manual. # # For advice on how to change settings please see # http://dev.mysql.com/doc/refman/8.0/en/server-configuration-defaults.html # # # CLIENT SECTION # ---------------------------------------------------------------------- # # The following options will be read by MySQL client applications. # Note that only client applications shipped by MySQL are guaranteed # to read this section. If you want your own MySQL client program to # honor these values, you need to specify it as an option during the # MySQL client library initialization. # [client] no-beep # pipe # socket=0.0 port=3306 [mysql] default-character-set=utf8 [mysqld] # 这是8.0.4的新特性 caching_sha2_password,在linux上面使用命宁 mysql -uroot -proot 可以链接,但是使用windows下面的navict链接不成功 default_authentication_plugin = mysql_native_password # These are commonly set, remove the # and set as required. character-set-server = utf8 basedir = D:\\Program Files\\mysql-8.0.11-winx64 datadir = D:\\Program Files\\mysql-8.0.11-winx64\\data port = 3306 server_id = 1 # 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 # General and Slow logging. log-output=FILE general-log=0 general_log_file="CUPID.log" slow-query-log=1 slow_query_log_file="CUPID-slow.log" long_query_time=10 # Binary Logging. # log-bin # Error Logging. log-error="CUPID.err" # 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 # 8.0.4版本的时候,用的是这个sql_mode,但在8.0.11版本中会报错,改成下面那个 # sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION sql-mode="STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION" default-storage-engine=INNODB innodb_log_file_size = 512M binlog_format=\'MIXED\' max_allowed_packet = 1G # innodb_file_per_table = 1 # innodb_file_format = Barracuda # 大小写是否敏感,0敏感 Linux下默认为0, Windows下默认值是 1, MacOS下默认值是 2(0敏感) lower_case_table_names = 1 innodb_strict_mode = 0 max_connections = 500
5、mysqld --install //安装MYSQL服务
6、mysqld --initialize --user=mysql --console //初始化mysql,并记下临时密码
7、net start mysql //启动mysql服务
8、SET PASSWORD = \'123456\'; //修改密码
或者使用 ALTER USER \'root\'@\'localhost\' IDENTIFIED BY \'123456\';
9、CREATE USER \'username\'@\'host\' IDENTIFIED BY \'password\'; (创建异地登录用户)
例:CREATE USER \'backup\'@\'10.0.0.2\' IDENTIFIED BY \'123456\'; (用户名为backup,密码123456,只允许10.0.0.2远程登录)
10、GRANT privileges ON databasename.tablename TO \'username\'@\'host\';(用户授权)
例:GRANT select,lock tables ON db1.* TO \'backup\'@\'%\';(授权db1数据库的select和lock tables权限给backup用户)
客户端下使用mysqldump备份
1、下载mysql绿色版,解压后,进入bin目录(客户端可以不用安装服务和初始化)
2、mysqldump -h主机名 -P端口 -u用户名 -p密码 数据库名 > 文件名.sql
mysqldump -h10.0.0.1 -P3310 -ubackup -p123456 db1 > db1.sql (备份db1数据库并保存为db1.sql文件)
安装mysql过程中,出现过的报错
1、丢失MSVCP140.DLL
解决方法:安装VC++2015运行库
2、安装VC++2015运行库失败
解决方法:控制面板-》Windows更新,更新到最新补丁
