DBD::mysql::db do failed: Table 'acl_access' was locked with a READ lock and can't be updated at /usr/bin/mysqlhotcopy line 483.
Locked 448 tables in 0 seconds.

mysql5.1升級至5.5之后，mysqlhotcopy備份拋出如下錯誤！

DBD::mysql::db do failed: Table 'acl_access' was locked with a READ lock and can't be updated at /usr/bin/mysqlhotcopy line 483. Locked 448 tables in 0 seconds.

因為5.5對lock語法進行了修改，而mysqlhotcopy使用的是原來的老語法，導致不能使用，升級mysqlhotcopy,即從mysql5.5 bin目錄中，將mysqlhotcopy替換原來的mysqlhotcopy程序！
