    Mysql主从复制的配置

     

    一、         my.ini配置文件的修改:

    1、  在主服务器上修改:

    [mysqld]

    #datadir=F:/Application/Mysql5.6/data

    port=5616

    event_scheduler=ON

    max_allowed_packet = 16M

    skip-name-resolve

    sql_mode="STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION"

    default_storage_engine=innodb

    innodb_file_per_table=1

    innodb_file_format = Barracuda

    innodb_open_files=1000

    innodb_buffer_pool_size=2188M

    innodb_log_file_size=50M

    max_connections=500

    max_connect_errors=5000

    max_prepared_stmt_count=50000

    innodb_print_all_deadlocks = 1

    innodb_lock_wait_timeout = 60

    #table_cache=2048

    transaction_isolation=REPEATABLE-READ

    loose-skip-external-locking

    innodb_flush_log_at_trx_commit=2

    #binlog_format="STATEMENT"

    #binlog_format="ROW"

    binlog_format="MIXED"

    sort_buffer_size=2M

    tmp_table_size=64M

    max_heap_table_size=64M

    slow_query_log=off

    slow_query_log_file = slow-queries.log

    #log-queries-not-using-indexes

    log-bin=matster-bin

    log-bin-index=matster-bin.index

    server-id=1

    expire-logs-days=3

    max_binlog_size = 512M

    log_bin_trust_function_creators=1

    query_cache_type=1

    query_cache_size=128M

    query_cache_limit=128M

    innodb_read_io_threads=8

    innodb_write_io_threads=8

     

    [client]

    port=5616

    #default-character-set=gbk

     

    [mysqldump]

    quick

    max_allowed_packet = 16M

     

    2、  在从服务器上修改:

    [mysqld]

    #basedir=D:/Application/mysql-5.6.16-slave

    #datadir=D:/Application/mysql-5.6.16-slave/data

    port=5600

    event_scheduler=ON

    max_allowed_packet = 16M

    skip-name-resolve

    sql_mode="STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION"

    default_storage_engine=innodb

    innodb_file_per_table=1

    innodb_file_format = Barracuda

    innodb_open_files=1000

    innodb_buffer_pool_size=1023M

    innodb_log_file_size=50M

    max_connections=500

    max_connect_errors=5000

    max_prepared_stmt_count=50000

    innodb_print_all_deadlocks = 1

    innodb_lock_wait_timeout = 60

    #table_cache=2048

    transaction_isolation=REPEATABLE-READ

    loose-skip-external-locking

    innodb_flush_log_at_trx_commit=2

    #binlog_format="STATEMENT"

    #binlog_format="ROW"

    #binlog_format="MIXED"

    sort_buffer_size=2M

    tmp_table_size=64M

    max_heap_table_size=64M

    slow_query_log=off

    slow_query_log_file = slow-queries.log

    #log-queries-not-using-indexes

    #log-bin=matster-bin

    #log-bin-index=matster-bin.index

    server-id=160

    #expire-logs-days=3

    relay-log=slave-relay-bin

    relay-log-index=slave-relay-bin.index

    #max_binlog_size = 512M

    #log_bin_trust_function_creators=1

    query_cache_type=1

    query_cache_size=128M

    query_cache_limit=128M

    innodb_read_io_threads=8

    innodb_write_io_threads=8

     

    [client]

    port=5600

    #default-character-set=gbk

     

    [mysqldump]

    quick

    max_allowed_packet = 16M

    二、在主服务器上创建复制用户

    DROP USER repl_user;

    CREATE USER repl_user ;

    GRANT replication slave on *.* to repl_user IDENTIFIED by 'fz';

    flush privileges;

    show master status;

    三、在从服务器上连接到主服务器

    change master to master_host='10.53.2.18',master_port=5616,master_user='repl_user',master_password='fz';

    START SLAVE; (可以单独启动和停止IO_THREAD或者SQL_THREAD,如start slave IO_THREAD,stop slave IO_THREAD或者start slave SQL_THREAD,stop slave SQL_THREAD)

    SHOW SLAVE STATUS;

    四、如果执行SHOW SLAVE STATUS后显示:

       Slave_io_Running:Yes

       Salve_SQL_Running:Yes

    则说明复制机制已经正常启动运行。

    五、常用于管理复制的命令:

    1、flush logs:强制轮换(rotate)二进制日志文件,得到一个完整的二进制日志文件;
    2、show binlog events:查看二进制日志文件里发生了哪些事件;
    3、reset master:删除所有二进制日志文件并清空二进制日志索引文件,在执行此命令时,确保没有slave连接到master上;
    4、reset slave:删除复制所用的所有文件,在执行此命令时,先执行stop slave.

     六、mysqlbinlog的使用

    读取远程服务器的二进制日志文件:
    mysqlbinlog -h192.168.2.8 -uBACKUP_user -p master-bin.000090 --short-form --read-from-remote-server

    七、

    如何使slave服务器将来自master的复制更新写入slave服务器的二进制日志:

    在my.ini中加入

    log_slave_updates=on

    八、过滤复制事件:

    有两种过滤事件的方法:

       1、master过滤;

             有两个选项:
             binlog-do-db=db 或者 binlog-ignore-do-db=db,前者表示过滤除db之外的所有的数据库;后者表示过滤db。二者不要同时使用。
       2、slave过滤
             有更多的选项:
             replicate-do-db=db 或者 replicate-ignore-do-db=db,含义与以上类似;
             replicatte-do-table=table或者replicate-wild-do-table=table name pattern(如 tbl% 表示开头为tbl的所有表);
             replicate-ignore-table=table或者replicate-wild-ignore-table=table name pattern;
