这里测试的环境是MySQL5.1.30,单核CPU，2G内存。
如果你下载的是源码，那么用内置的yaSSL或者用第三方的OpenSSL来编译MySQL.
OpenSSL下载地址：http://www.openssl.org/
关于SSL加密传输的原理可以随便GOOGLE一下。
要注意的事项见这里：
http://dev.mysql.com/doc/refman/5.0/en/secure-using-ssl.html
不过用SSL之前要想清楚，因为客户端和服务器端的连接以及传输速度会降低。
1. 下面我们来看安装过程。
先看一下你自己的mysqld支持SSL与否。
mysql> select @@have_ssl;
+------------+
| @@have_ssl |
+------------+
| NO |
+------------+
1 row in set (0.01 sec)
如果不支持，我们来看看安装过程。
tar zxf mysql-5.1.30.tar.gz
./configure --with-ssl --PRefix=/usr/local/mysql-ytt
configure 过程中有什么问题，见自己的config.log。
如果没有问题，欢迎页面就会出现：
...
Thank you for choosing MySQL!
然后
make
make install;
这个时间比较长，我只有一个核的CPU。半个小时左右才搞完。
COPY一个配置文件。
[root@ytt2 support-files]# cp my-medium.cnf /usr/local/mysql-ytt/my.cnf
添加如下信息。
port = 3309
socket = /tmp/mysql3309.sock
basedir=/usr/local/mysql-ytt
datadir=/data/mysql-ytt
建立MySQL的DATA目录来存放数据。
[root@ytt2 mysql-ytt]# cd /data/
[root@ytt2 data]# mkdir mysql-ytt
[root@ytt2 data]# chown -R mysql.mysql mysql-ytt/
下来初始化数据库。
[root@ytt2 bin]# ./mysql_install_db --defaults-file=/usr/local/mysql-ytt/my.cnf
2. 添加SSL认证过程。
这个脚本COPY到文件里面然后执行。
具体解释：

echo "DONE!"
#------------------------------------------------------------
#-------------------END SCRIPT--------------------
#------------------------------------------------------------
然后执行：
[root@ytt2 ssl]# chmod 755 ssl_script
[root@ytt2 ssl]# ./ssl_script
完了后
然后在MySQL配置文件里面添加如下信息：
[client]
ssl-ca=/home/david_yeung/ssl/openssl/cacert.pem
ssl-cert=/home/david_yeung/ssl/openssl/client-cert.pem
ssl-key=/home/david_yeung/ssl/openssl/client-key.pem
[mysqld]
ssl-ca=/home/david_yeung/ssl/openssl/cacert.pem
ssl-cert=/home/david_yeung/ssl/openssl/server-cert.pem
ssl-key=/home/david_yeung/ssl/openssl/server-key.pem
启动mysqld
[root@ytt2 mysql-ytt]# /usr/local/mysql-ytt/bin/mysqld_safe --defaults-file=/usr/local/mysql-ytt/my.cnf &
[1] 24239
3. 授权SSL 测试用户：
[root@ytt2 ssl]# /usr/local/mysql-ytt/bin/mysql --defaults-file=/usr/local/mysql-ytt/my.cnf
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 11
server version: 5.1.30-log Source distribution
Type ''help;'' or ''\h'' for help. Type ''\c'' to clear the buffer.
mysql> grant all privileges on *.* to root@''192.168.2.88'' identified by ''love_root'' require ssl;
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql> \q
Bye
[root@ytt2 ssl]#
添加iptables 规则
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 3309 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT
重启iptables.
[root@ytt2 ssl]# /etc/init.d/iptables restart
Flushing firewall rules: [ OK ]
Setting chains to policy ACCEPT: filter [ OK ]
Unloading iptables modules: [ OK ]
Applying iptables firewall rules: [ OK ]
Loading additional iptables modules: ip_conntrack_netbios_n[ OK ]
4.测试一下效果。
把客户端的认证传到192.168.2.88的windows机器上。
然后添加my.ini.
比如我的：
[client]
port=3306
ssl-ca="D:/LAMP/MySQL5.0/SSL_key/cacert.pem"
ssl-cert="D:/LAMP/MySQL5.0/SSL_key/client-cert.pem"
ssl-key="D:/LAMP/MySQL5.0/SSL_key/client-key.pem"
重启MySQL服务器。
C:\>net stop mysql5
The MySQL5 service is stopping..
The MySQL5 service was stopped successfully.
C:\>net start mysql5
The MySQL5 service is starting.
The MySQL5 service was started successfully.
测试连接：
C:\>mysql -uroot -p -h192.168.2.41 -P3309
Enter password: *********
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 13

Type ''help;'' or ''\h'' for help. Type ''\c'' to clear the buffer.
