を て、 はパスワードの だと っていましたが、パスワードはコピーされていて、 はなく、 は きくありません.checkの で の を てみましょう.
2,check 、ping ipアドレス、OKです.[xxx@xxx-c004db1 shared]$ ping 10.24.54.18

4、ファイアウォールサービスiptables stopを じて、slaveを しますか、それともLast_を しますか.IO_Errno:1045エラーです.
5、リモートアクセスマスターライブラリmysqlサービス、エラーは の りです.[xxx@xxx-c004db1 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)

アカウントをよくチェックすると、grant を していたとき、パスワード にスペースが1つ えたため、 のテキストエディタにスペースが されなかったため、 つかりませんでした.
6、 :スペースを し、grant を し、slaveを し、OK.mysql> show slave status\G
