同一服务器MYSQL主从配置
在一台服务器上安装2个MYSQL服务,配置MYSQL服务的主从管理。
(1)修改my.ini文件(主)。
添加
log-bin=E:/MySqlData/mysql-bin//日志文件的位置
server-id=1 //ID标识
binlog-do-db=databaseName//需要同步的数据库
binlog-ignore-db=mysql //不需要同步的数据库
binlog-ignore-db=test
binlog-ignore-db=information_schema
replicate-wild-ignore-table=databaseName.table% //忽视同步的表,规则查文档
expire_logs_days=1 //1天时间自动清理二进制日志
innodb_flush_log_at_trx_commit=1//每一次事务提交或事务外的指令都需要把日志写入(flush)硬盘
sync-binlog=1 //使binlog在每N次binlog写入后与硬盘 同步
port=3306 //主数据库的端口
basedir="D:/java/javasoft/MYSQL/" //数据库安装路径
datadir="E:/MySqlData/Data/" //数据库数据目录
修改my1.ini文件(从),此文件新建一个即可。为从MYSQL服务的配置文件。
server-id=2
master-host=127.0.0.1 //主机名
master-user=name //主数据库用户名(添加数据库用户参考下面内容)
master-pass=password //主数据库密码
master-port=3306
master-connect-retry=60
replicate-do-db=database 需要备份的数据库名
replicate-ignore-db=mysql 忽略的数据库
expire_logs_days=1 //二进制日志自动删除的天数
port=3307 //端口和主的不一样
basedir="D:/java/javasoft/MYSQL/"
datadir="E:/MySqlData/data1/" //数据目录也不一样
添加数据库用户:
GRANT REPLICATION SLAVE ON *.* TO '用户名'@'localhost' IDENTIFIED BY '密码'
添加MYSQL服务进windows服务里的dos命令语句。
D:/java/javasoft/MYSQL/bin/mysqld --install serverName --defaults-file=d:/java/javasoft/MYSQL/my.ini
删除服务的命令:sc delete serverName
先启动主数据库的服务,再启动从数据库的服务,测试即可。

The string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.

The best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.
