日志显示:

May 21 17:39:22 local vsftpd[3966]: sqlLog called.
May 21 17:39:22 local vsftpd[3966]: pam_mysql: error: sqllog set but logtable not set
May 21 17:39:22 local vsftpd[3966]: pam_mysql: error: sqllog set but logmsgcolumn not set
May 21 17:39:22 local vsftpd[3966]: pam_mysql: error: sqllog set but logusercolumn not set
May 21 17:39:22 local vsftpd[3966]: pam_mysql: error: sqllog set but loghostcolumn not set
May 21 17:39:22 local vsftpd[3966]: pam_mysql: error: sqllog set but logtimecolumn not set

请教高手能否在mysql里直接关闭sqllog?
