在MySQL5.5/5.6里版本里,设置同步复制过滤,例如设置忽略掉test库的t2表,你需要在my.cnf配置文件里增加:
replicate-ignore-table=test.t2
必须重启mysql服务进程才能生效。
在MySQL5.7里,通过一个新的命令,可以支持在线动态修改,而不须重启mysql进程就生效。
Example:
CHANGE REPLICATION FILTER REPLICATE_DO_DB=(db1,db2); CHANGE REPLICATION FILTER REPLICATE_IGNORE_DB=(db1,db2); CHANGE REPLICATION FILTER REPLICATE_DO_TABLE=(db1.t1); CHANGE REPLICATION FILTER REPLICATE_IGNORE_TABLE=(db2.t2); CHANGE REPLICATION FILTER REPLICATE_WILD_DO_TABLE=('db.t%'); CHANGE REPLICATION FILTER REPLICATE_WILD_IGNORE_TABLE=('db%.a%'); CHANGE REPLICATION FILTER REPLICATE_REWRITE_DB=((from_db, to_db));
增强了易用性,方便了不少。

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
