Mysql主从同步配置错误信息
环境：主从服务器上的MySQL数据库版本同为5.1.44,服务器系统为redhat5.4-i386
主机IP：192.168.0.1
从机IP：192.168.0.2
一. MySQL主服务器配置
编辑配置文件/etc/my.cnf
server-id = 1
log-bin=mysql-bin
log-slave-updates
建立用户
mysql> grant replication slave on *.* to slave@192.168.0.2 identified by ‘111′;
mysql> SHOW MASTER STATUS;
+------------------+----------+--------------+------------------+
| File | Position | Binlog_do_db | Binlog_ignore_db |
+------------------+----------+--------------+------------------+
| mysql-bin.000003 | 239 | | |
+------------------+----------+--------------+------------------+
二.MySQL从服务器配置
编辑 /etc/my.cnf
server-id=2
log-bin=mysql-bin
master-host=192.168.0.1
master-user=slave
master-password=111
master-port=3306
log-slave-updates
在SLAVE上设置同步
mysql> slave stop;
mysql> CHANGE MASTER TOMASTER_HOST='192.168.0.1',MASTER_USER='slave',MASTER_PASSWORD='111',MASTER_LOG_FILE='mysql-bin.000001',MASTER_LOG_POS=106;
启动SLAVE服务
mysql> slave start;
查看SLAVE状态
mysql> start slave io_thread;
Query OK, 0 rows affected (0.00 sec)
mysql> show slave status\G

重新做了七遍，每次都是Slave_IO_Running: No，尝试着用startslave io_thread启用IO，但都失败了，这是为什么呢？
