您需要转义引号 - 或者更简单......切换到单引号，并转义它们(它们更少!)

$sql = 'SELECT CONCAT("sshpass -p ""Password""  rsync   -avvtzh -e  ""ssh -o StrictHostKeyChecking=no""  --log-file=""/home/toor/rsync2.log""",   login,"@", ftp_addr, " :", camera_name,"/",    "/",`'home`',"/",login, "/", camera_name)
FROM inteliviz.cameras order by id INTO OUTFILE \'/tmp/wptitles2.csv\' LINES TERMINATED BY \'\r\n\'';
