第二部分, 在一台服務器構建多mysql主服務。
**********************************************************
提示:建立一個帳號,專門用于下面主從復制,本例用的的帳號repl, 口令為:'1234567890', 可讓其擁有select_priv,reload_priv,process_priv,grant_priv,super_priv,repl_slave_priv,repl_client_priv權限，並能通過任何客戶進行訪問,即訪問客戶為'%'。
主要是修改my.cnf中的內容,讓每個mysql生成自己的bin-log文件及各自的運行環境，現貼上我的my.cnf全部內容,相關參數與請參考mysql 官文手冊。

啟動多mysql服務都是相同的,
db-app:/ # /usr/local/mysq/bin/mysqld_multi --config-file=/etc/my.cnf start 1-4
