mysql報錯RSA private key file not found怎麼解決

安裝mysql報錯

[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.

解決方法如下：

1.檢查是否安裝openssl

$rpm -qa openssl

openssl-1.0.0-20.el6_2.5.x86_64

2.利用openssl產生公有和私有key

$ openssl genrsa -out mykey.pem 1024

Generating RSA private key, 1024 bit long modulus
..........++++++
.++++++
e is 65537 (0x10001)
$ openssl rsa -in mykey.pem -pubout -out mykey.pub

writing RSA key

3.修改key的權限

$ chmod 400 mykey.pem
$ chmod 444 mykey.pub
chown mysql:mysql mykey.pem
chown mysql:mysql mykey.pub

4.把公私有key的路徑加入my.cnf中

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

5.重啟mysql

SHOW STATUS查看Rsa_public_key状态，如果不为空，则OK.
mysql> SHOW STATUS LIKE 'Rsa_public_key'\G
