我想知道mysqldump的所有常见位置.我提出的清单如下：
'/usr/bin/mysqldump', //Linux
'/usr/local/mysql/bin/mysqldump', //Mac OS X
'/usr/local/bin/mysqldump', //Linux
'/usr/mysql/bin/mysqldump'; //Linux
通常mysqldump不在路径中,所以我试图让所有的位置都可以查看.(我是从php脚本运行的)
有什么我想念的吗？
解决方法:
除了你在问题中给出的那些之外,我找不到任何其他路径.但是,我想到的一件事是,在大多数情况下,mysqldump应该与mysql二进制文件位于同一目录中.现在,在大多数情况下,mysql命令也将在路径中.
因此,在大多数情况下,您可以将两个逻辑组合在一起以获得mysqldump二进制文件的位置,如下所示：
function detect_mysqldump_location() {
// 1st: use mysqldump location from `which` command.
$mysqldump = `which mysqldump`;
if (is_executable($mysqldump)) return $mysqldump;
// 2nd: try to detect the path using `which` for `mysql` command.
$mysqldump = dirname(`which mysql`) . "/mysqldump";
if (is_executable($mysqldump)) return $mysqldump;
// 3rd: detect the path from the available paths.
// you can add additional paths you come across, in future, here.
$available = array(
'/usr/bin/mysqldump', // Linux
'/usr/local/mysql/bin/mysqldump', //Mac OS X
'/usr/local/bin/mysqldump', //Linux
'/usr/mysql/bin/mysqldump' //Linux
);
foreach($available as $apath) {
if (is_executable($apath)) return $apath;
}
// 4th: auto detection has failed!
// lets, throw an exception, and ask the user to provide the path instead, manually.
$message = "Path to \"mysqldump\" binary could not be detected!\n"
$message .= "Please, specify it inside the configuration file provided!"
throw new RuntimeException($message);
}
现在,您可以将上述功能用于您的目的.并且,如果上述函数抛出错误,则为用户提供手动提供mysqldump二进制的显式路径的方法.应该适用于您的用例:)
