[Note] RSA private key file not found: /db/mysql5.6/data//private_key.pem. Some authentication plugins will not work. [Note] RSA public key file not found: /db/mysql5.6/data//public_key.pem. Some authentication plugins will not work.
解决方法如下：
$rpm -qa openssl openssl-1.0.0-20.el6_2.5.x86_64
$ openssl genrsa -out mykey.pem 1024Generating RSA private key, 1024 bit long modulus ..........++++++ .++++++ e is 65537 (0x10001)
$ openssl rsa -in mykey.pem -pubout -out mykey.pubwriting RSA key
$ chmod 400 mykey.pem$ chmod 444 mykey.pubchown mysql:mysql mykey.pemchown mysql:mysql mykey.pub
sha256_password_private_key_path=mykey.pem sha256_password_public_key_path=mykey.pub如果key放在datadir目录下，直接写key名即可。否则要指定key的全路径
SHOW STATUS查看Rsa_public_key状态，如果不为空，则OK.
