1.安裝，sudo apt-get install MySQL-server
2：密碼最好一致 update MySQL.user set password=passWord（”新密碼”）where User=”root
3.配置這兩台服務器上配置my.cnf，這兩台服務器都要配置
首先要備份my.cnf,若是下面的操作出現問題要使用備份恢復原有可用的配置文件，語句：cp /etc/mysql/my.cnf /etc/MySQL/my.cnf-backup
然後，編輯my.cnf,使用語句：sudo gedit /etc/MySQL/my.cnf

# The MySQL database server configuration file.
#
# You can copy this to one of:
# - "/etc/MySQL/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.
#
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
#
# For explanations see
# http://dev.mysql.com/doc/MySQL/en/server-system-variables.Html
# This will be passed to all MySQL clIEnts
# It has been reported that passWords should be enclosed with ticks/quotes
# escpecially if they contain "#" chars...

表明成功了！！
測試數據要注意的是在一個服務器上添加了數據庫，在另個一個也要點添加，然後裡面的表就會自動同步了！
