1  修复集群,start slave 报错如下:

看问题,一开始怀疑是密码问题,但是密码都是复制上来的,没有变动,问题不大,还是看看check下别的情况吧。
 
2 ,check问题所在,ping ip地址,是OK的。
[python] 
[[email protected] shared]$ ping 10.24.54.18  
PING 10.24.54.18 (10.24.54.18) 56(84) bytes of data.  
64 bytes from 10.24.54.18: icmp_seq=1 ttl=64 time=0.321 ms  
64 bytes from 10.24.54.18: icmp_seq=2 ttl=64 time=0.370 ms  
^C  
--- 10.24.54.18 ping statistics ---  
2 packets transmitted, 2 received, 0% packet loss, time 1417ms  
rtt min/avg/max/mdev = 0.321/0.345/0.370/0.030 ms  
[[email protected] shared]$   

 

 
3 ,access 端口3306,也是OK的。
[python] 
[[email protected] shared]$ ssh -v -p3306 10.24.54.18   
OpenSSH_5.3p1, OpenSSL 1.0.0-fips 29 Mar 2010

debug1: identity file /home/xxx/.ssh/id_rsa type -1  
debug1: identity file /home/xxx/.ssh/id_dsa type -1  
debug1: ssh_exchange_identification: O  
^C  

 

 
4,关闭防火墙service iptables stop,然后重启slave,还是报 Last_IO_Errno: 1045错误。
 
5,远程访问主库 服务,报错如下:
[python] 
[[email protected] shared]$ mysql -h 10.24.54.18 -ureplication -pxxx  
ERROR 1045 (28000): Access denied for user 'replication'@'xxx-xxx.abn-sjl.ea.com' (using password: YES)  
[[email protected] shared]$   

 

 
仔细检查帐户,发现原来是执行grant语句的时候,密码串里面多了一个空格导致,同事的文本编辑器里面空格显示不明显,所以没有发现。
 
6,修复:去掉空格,重新执行grant语句,再重新启动slave,OK。
[sql] 
mysql> show slave status\G
