在主服務器到主服務器複製MySQL服務器期間出錯

Question

我已經在MySQL服務器5.2上用我現有的數據庫設置了主服務器到主服務器的複製。我成功地將名爲Master 1的數據複製到Master 2，並將其命名爲複製。但我師父1得到錯誤，當我嘗試連接到掌握2.下面是他們的詳細信息：

請幫助我。您的解決方案將指導我解決任務。先謝謝你。 問候， Udhyan。

Answer 1

確保您可以從主1 DB的主機連接到主機（2）的MySQL的插槽，你可以驗證，如果你能夠通過shell命令連接：如果此命令成功

telnet master-2-ip MYSQLPORT //3306 is the default port for mysql 

（這意味着你沒有獲得「連接被拒絕」），嘗試連接：

mysql -u user -p'password' -H host -P port 

如果問題不張貼在/ var你的mysql日誌連接問題/日誌可以幫助多一點。
