mysql通过ssl的方式生成秘钥具体生成步骤

-- mysql ssl 生成秘钥 
1 check ssl是否已经开启 
mysql> show variables like '%ssl%'; 
+---------------+----------+ 
| Variable_name | Value | 
+---------------+----------+ 
| have_openssl | DISABLED | 
| have_ssl | DISABLED | 
| ssl_ca | | 
| ssl_capath | | 
| ssl_cert | | 
| ssl_cipher | | 
| ssl_crl | | 
| ssl_crlpath | | 
| ssl_key | | 
+---------------+----------+ 
9 rows in set (0.00 sec) 

2 没有开启,所以打开 
在my.cnf末尾端设置ssl 参数， 然后重新启动mysql服务即可 
mysql> show variables like '%ssl%'; 
+---------------+-------+ 
| Variable_name | Value | 
+---------------+-------+ 
| have_openssl | YES | 
| have_ssl | YES | 
| ssl_ca | | 
| ssl_capath | | 
| ssl_cert | | 
| ssl_cipher | | 
| ssl_crl | | 
| ssl_crlpath | | 
| ssl_key | | 
+---------------+-------+ 
9 rows in set (0.00 sec) 

3 通过openssl生成证书的配置, 在mysql db server上生成秘钥 
mkdir -p /etc/mysql/newcerts/ 
cd /etc/mysql/newcerts/ 
3.1 openssl genrsa 2048 > ca-key.pem 
3.2 openssl req -new -x509 -nodes -days 1000 -key ca-key.pem > ca-cert.pem 
[root@mysql newcerts]# openssl req -new -x509 -nodes -days 1000 -key ca-key.pem > ca-cert.pem 
You are about to be asked to enter information that will be incorporated 
into your certificate request. 
What you are about to enter is what is called a Distinguished Name or a DN. 
There are quite a few fields but you can leave some blank 
For some fields there will be a default value, 
If you enter '.', the field will be left blank. 
----- 
Country Name (2 letter code) [XX]:ch 
State or Province Name (full name) []:shh 
Locality Name (eg, city) [Default City]:shh 
Organization Name (eg, company) [Default Company Ltd]:xx 
Organizational Unit Name (eg, section) []:db 
Common Name (eg, your name or your server''s hostname) []:mysql.yest.nos 
Email Address []:xx@xx.com 
3.3 openssl req -newkey rsa:2048 -days 1000 -nodes -keyout server-key.pem > server-req.pem 
[root@mysql newcerts]# openssl req -newkey rsa:2048 -days 1000 -nodes -keyout server-key.pem > server-req.pem 
Generating a 2048 bit RSA private key 
.......................................................................................................+++ 
..........................................................+++ 
writing new private key to 'server-key.pem'

Common Name (eg, your name or your server''s hostname) []:mysql.yest.nos 
Email Address []:xx@xx.com 
Please enter the following 'extra' attributes 
to be sent with your certificate request 
A challenge password []:820923 
An optional company name []:xx 

4 在mysql db server客户端生成ssl文件 
4.1 openssl x509 -req -in server-req.pem -days 1000 -CA ca-cert.pem -CAkey ca-key.pem -set_serial 01 > server-cert.pem 
[root@mysql newcerts]# openssl x509 -req -in server-req.pem -days 1000 -CA ca-cert.pem -CAkey ca-key.pem -set_serial 01 > server-cert.pem 
Signature ok 
subject=/C=ch/ST=shh/L=ssh/O=ea/OU=db/CN=mysql.yest.nos/emailAddress=cm@xx.com 
Getting CA Private Key 
4.2 openssl req -newkey rsa:2048 -days 1000 -nodes -keyout client-key.pem > client-req.pem 
[root@mysql newcerts]# openssl req -newkey rsa:2048 -days 1000 -nodes -keyout client-key.pem > client-req.pem 
Generating a 2048 bit RSA private key 
.......+++ 
........................................................+++ 
writing new private key to 'client-key.pem'

openssl x509 -req -in client-req.pem -days 1000 -CA ca-cert.pem -CAkey ca-key.pem -set_serial 01 > client-cert.pem 
[root@mysql newcerts]# openssl x509 -req -in client-req.pem -days 1000 -CA ca-cert.pem -CAkey ca-key.pem -set_serial 01 > client-cert.pem 
Signature ok 
subject=/C=ch/ST=shh/L=shh/O=ea/OU=db/CN=mysql.yest.nos/emailAddress=cm@xx.com 
Getting CA Private Key

[]copy clent.* 3个文件到客户端机器上面/opt/mysql/ssl/去。 

6 登陆验证 
mysql -uxxx -pxxxx --ssl-ca=/opt/mysql/ssl/ca-cert.pem --ssl-cert=/opt/mysql/ssl/server-cert.pem --ssl-key=/opt/mysql/ssl/server-key.pem
