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'

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 

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'

Common Name (eg, your name or your server''s hostname) []:mysql.yest.nos 

Email Address []:cx@xx.com 

Please enter the following 'extra' attributes 

to be sent with your certificate request 

A challenge password []:820923 

An optional company name []:xx 

4.3 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 

5、[]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
