安装mysql报错
[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:
1.检查是否安装openssl
$rpm -qa openssl
openssl-1.0.0-20.el6_2.5.x86_64
2.利用openssl生成公有和私有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的权限
$ chmod 400 mykey.pem
$ chmod 444 mykey.pubchown mysql:mysql mykey.pemchown mysql:mysql mykey.pub
4.把公私有key的路径加入到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.重启mysql
SHOW STATUS查看Rsa_public_key状态,如果不为空,则OK.
mysql> SHOW STATUS LIKE Rsa_public_keyG
