I am creating the MySQL master-slave replication on CentOS 7 below are the configuration files details of both the server:
Master server's my.cnf
[mysqld]
server-id=1
log-bin=mysql-bin
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
symbolic-links=0
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
Slave Server's my.cnf
[mysqld]
server-id=2
replicate-wild-do-table=db1%.%
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
symbolic-links=0
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
Database details given below:
Master Server
create database db1;
create table db1.dbtb1(name varchar(100));
Slave Server
create database db1slave;
create table db1slave.dbtb1(name varchar(100));
AS you can see the Database name on both the sever are different for that I have use the below statement into the slave server for replication.
replicate-wild-do-table=db1%.%
But when I try to insert data into the Master Data base server I got the below error or slave server status:
Error 'Table 'db1.dbtb1' doesn't exist' on query. Default database: ''. Query: 'insert into db1.dbtb1 values ('Punu')'

If I will take the same database name it will work fine. But as per my requirement I can't put the database name same on both the server.
Simply I want that when the table "dbtb1" updated in Master server database then it will be replicated to the slave database table.
I have also try the below options in the slave my.cnf file:
1
replicate-wild-do-table=db1%.dbtb1
2
replicate-rewrite-db="db1->db1slave"
Above option will work fine if I insert record but it will not reflect when I delete or update record.
3
replicate-wild-do-table=%.dbtb1
