Slave_IO_Running: Connecting 错误处理

一、主服务器上

摘要：重新配置一下主从及半同步复制

mysql> GRANT REPLICATION SLAVE ON *.* to 'root'@'192.168.246.141' identified by 'ayilian';
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql> show master status;
+------------------+----------+--------------+------------------+
| File             | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+----------+--------------+------------------+
| mysql-bin.000001 |      107 | aa           | mysql            |
+------------------+----------+--------------+------------------+
1 row in set (0.00 sec)

mysql> INSERT INTO bbb(df) VALUES(now());
Query OK, 1 row affected (0.00 sec)

在主上写入数据

二、从服务器上

###

mysql> reset master;
Query OK, 0 rows affected (0.01 sec)

mysql> show master status;
+------------------+----------+--------------+------------------+
| File             | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+----------+--------------+------------------+
| mysql-bin.000001 |      107 |              |                  |
+------------------+----------+--------------+------------------+
1 row in set (0.00 sec)

###

mysql> CHANGE MASTER TO MASTER_HOST='192.168.246.140',
    -> MASTER_USER='root',
    -> MASTER_PASSWORD='ayilian',
    -> MASTER_LOG_FILE='mysql-bin.000001',
    -> MASTER_LOG_POS=107;
Query OK, 0 rows affected (0.03 sec)

3###

mysql> slave start;
Query OK, 0 rows affected (0.00 sec)

mysql> show slave status\G;
*************************** 1. row ***************************

三、测试数据是否正常

1.主服务器：

mysql> INSERT INTO bbb(df) VALUES(now());
Query OK, 1 row affected (0.01 sec)

mysql> select * from bbb;
+---------------------+
| df                  |
+---------------------+
| 2015-05-30 11:21:18 |
+---------------------+
1 row in set (0.00 sec)

2.从务器：

mysql> select * from bbb;
+---------------------+
| df                  |
+---------------------+
| 2015-05-30 11:21:18 |
+---------------------+
1 row in set (0.00 sec)
