java程序使用ssl证书连接mysql

1. 在mysql服务器上生成证书
    openssl genrsa 2048 > ca-key.pem
    openssl req -new -x509 -nodes -days 3600 -key ca-key.pem -out ca.pem
    openssl req -newkey rsa:2048 -days 3600 -nodes -keyout server-key.pem -out server-req.pem
    openssl rsa -in server-key.pem -out server-key.pem
    openssl x509 -req -in server-req.pem -days 3600  -CA ca.pem -CAkey ca-key.pem -set_serial 01 -out server-cert.pem

2. 生成客户端连接mysql证书
    openssl req -newkey rsa:2048 -days 3600  -nodes -keyout client-key.pem -out client-req.pem
    openssl rsa -in client-key.pem -out client-key.pem
    openssl x509 -req -in client-req.pem -days 3600  -CA ca.pem -CAkey ca-key.pem -set_serial 01 -out client-cert.pem
    openssl verify -CAfile ca.pem server-cert.pem client-cert.pem

3. 验证证书
    openssl verify -CAfile ca.pem server-cert.pem client-cert.pem
    输出结果:
        server-cert.pem: OK
        client-cert.pem: OK    　

4. 配置mysql
    [client]
    ssl-cert = /etc/mysql_cert/ssl/client-cert.pem
    ssl-key = /etc/mysql_cert/ssl/client-key.pem
    注意:如果是做了主从，需要把主的证书拷贝到从

    [mysqld]
    ssl-ca=/etc/mysql_cert/ssl/ca.pem
    ssl-cert=/etc/mysql_cert/ssl/server-cert.pem
    ssl-key=/etc/mysql_cert/ssl/server-key.pem

    show global variables like '%ssl%';

5. 授权用户ssl登录
    grant select on *.* to 'paylabs_app2_plb'@'xxxxx' identified by '123456' require ssl;
    使用\s;查看用户是否使用证书登录

　　

6. java程序连接mysql
    需要将mysql上的client证书和ca拷贝到应用服务器
    生成以下两个文件:
    keytool -importcert -alias Cacert -file ca.pem  -keystore truststoremysql -storepass 123456
    openssl pkcs12 -export -in client-cert.pem -inkey client-key.pem -name "xxx" -passout pass:123456 -out client-keystore.p12
    keytool -importkeystore -srckeystore client-keystore.p12 -srcstoretype pkcs12 -srcstorepass 123456-destkeystore keystoremysql -deststoretype JKS -deststorepass 123456
