编译后MySQL v5.7.11安装出错

在从源代码编译安装后尝试启动
mysql服务器时,我在MAC OS X 10.11中遇到以下错误.

keyring_file不可读.

我试图使用以下命令启动服务器.

./mysqld start

在终端中生成以下错误.

最佳答案 如果您检查
keyring_file_data mysql manual entry,您将看到此选项的含义:

The path name of the data file used for secure data storage by the
keyring_file plugin. The file location should be in a directory
considered for use only by the keyring_file plugin. For example, do
not locate the file under the data directory.

Do not use the same keyring_file data file for multiple MySQL
instances. Each instance should have its own unique data file.

The default file name is keyring, located in a directory that is
platform specific and depends on the value of the INSTALL_LAYOUT CMake
option, as shown in the following table. To specify the default
directory for the file explicitly if you are building from source, use
the INSTALL_MYSQLKEYRINGDIR CMake option.

您还将看到各种Linux发行版处理它的默认值.

在/ var / lib中/ MySQL的,钥匙圈/钥匙圈

所以答案应该是可以安全地忽略.但是你希望innodb文件加密my.cnf应该是这样的:

[mysqld]
keyring_file_data = /var/lib/mysql-keyring/keyring

但是,这可能无法解决您的问题.
