server1_nobinlog, Error: Too many connections
メンテナンス担当者は直接テストの機械を再起動し、/usrディレクトリが存在しないので、新しいmysqlを再インストールし、テストライブラリを再起動してmyshardを再起動します.ポートによっては起きられないものもあります.起きられないものもあります.
ポートのログを表示できません
myshard報mysqlの接続数がいっぱいになったことを発見し、接続数を増やした.
myshardのポートを再起動すると、スムーズに起動できます
この時810ポートがまだ起きられないことを発見して、ログを見てbinlogを報告しますsync.propertiesファイルは存在しません
このファイルはmyshardの下のMySQLがbinlogを生成する位置点を記録し、mysql-binに相当する.indexですがサイズは0で、
MySQLを交換したので削除して新しい位置点を再生成させ、8810を再起動できました
