基于 bin log 搭建主从模式

规划: 3306 是主库; 3307 实例是从库

  • 主库
create USER 'repuser'@'%' IDENTIFIED WITH mysql_native_password BY 'repuser' ;
GRANT REPLICATION SLAVE ON *.* TO 'repuser'@'%';
FLUSH PRIVILEGES;SHOW BINARY LOG STATUS
+------------------+----------+--------------+------------------+-------------------+
| File             | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+------------------+----------+--------------+------------------+-------------------+
| mysql-bin.000008 |      443 |              |                  |                   |
+------------------+----------+--------------+------------------+-------------------+
  • 从库
stop replica;
change replication source to source_host='127.0.0.1', source_port=3306, source_user='repuser', source_password='repuser', source_log_file='mysql-bin.000008', source_log_pos=443;
show replica status\G第一次报错如下:Last_IO_Errno: 2061Last_IO_Error: Error connecting to source 'repuser@127.0.0.1:3306'. This was attempt 6/10, with a delay of 60 seconds between attempts. Message: Authentication plugin 'caching_sha2_password' reported error: Authentication requires secure connection.然后在主库与从库配置文件的 mysqld 中 , 都启用了 mysql_native_password=on, 然后重启了数据库服务
然后同步状态正常如下;

IQ信号和实信号的关系与转换的matlab实现

IQ信号和实信号的关系与转换的matlab实现

IQ信号 IQ信号通常是指两路正交的信号（I路和Q路），在实际信号采样中，通常会进行IQ采样，将实信号转换为复基带信号进行存储。 IQ信号转实信号 IQ信号转为实信号，其实就是将IQ两路正交信号通过上变频合并为一个实数的带通信号，这通常在通信系统中用于将基带信号调制到载…
