安装mysql报错

[Note]RSAprivatekeyfilenotfound:/db/mysql5.6/data//private_key.pem.Someauthenticationpluginswillnotwork.[Note]RSApublickeyfilenotfound:/db/mysql5.6/data//public_key.pem.Someauthenticationpluginswillnotwork.

解决方法如下：

1.检查是否安装openssl

$rpm-qaopensslopenssl-1.0.0-20.el6_2.5.x86_642.利用openssl生成公有和私有key

$opensslgenrsa-outmykey.pem1024GeneratingRSAprivatekey,1024bitlongmodulus..........++++++.++++++eis65537(0x10001)

$opensslrsa-inmykey.pem-pubout-outmykey.pubwritingRSAkey3.修改key的权限

$chmod400mykey.pem$chmod444mykey.pubchownmysql:mysqlmykey.pemchownmysql:mysqlmykey.pub4.把公私有key的路径加入到my.cnf中

sha256_password_private_key_path=mykey.pemsha256_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

SHOWSTATUS查看Rsa_public_key状态，如果不为空，则OK.
