建立MySQL的SSL连接通道

  通常我们在编译MySQL的时候都加入了with-openssl选项,但这并不代表MySQL已经支持了OpenSSL连接,我们可以通过如下命令进行检测:

  SHOW VARIABLES LIKE 'have_openssl';

  如果显示DISABLED则表明MySQL尚不支持OpenSSL.

  建立SSL证书

  ;;建几个目录和文件

  mkdir /usr/local/myssl

  cd /usr/local/myssl

  mkdir private newcerts

  touch index.txt

  echo "01" > serial

  ;;拷贝一份OpenSSL的缺省配置到当前目录

  cp /usr/local/openssl/openssl.cnf .

  ;;修改当前目录下的openssl.cnf,将。/demoCA替换为/usr/local/myssl,replace的具体用法见man

  replace ./demoCA /usr/local/myssl —— /usr/local/myssl/openssl.cnf

  ;;建立根证书

  openssl req -new -x509 -keyout private/cakey.pem -out cacert.pem -config openssl.cnf

  # Sample output:

  # Using configuration from /usr/local/myssl/openssl.cnf

  # Generating a 1024 bit RSA private key

  # ……++++++

  # ……++++++

  # writing new private key to '/usr/local/myssl/private/cakey.pem'

  # Enter PEM pass phrase:

  # Verifying password - Enter PEM pass phrase:

  # ——

  # 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) [AU]:CN

  # State or Province Name (full name) [Some-State]:ZJ

  # Locality Name (eg, city) []:JX

  # Organization Name (eg, company) [Internet Widgits Pty Ltd]:Centeur CA

  # Organizational Unit Name (eg, section)[] :HN

  # Common Name (eg, YOUR name)[] :MySQL admin

  # Email Address []:lypdarling@gmail.com

  ;;建立服务端证书

  openssl req -new -keyout server-key.pem -out server-req.pem -days 3600 -config openssl.cnf

  # Sample output:

  # Using configuration from /usr/local/myssl/openssl.cnf

  # Generating a 1024 bit RSA private key

  # ……++++++

  # ……++++++

  # writing new private key to '/usr/local/myssl/server-key.pem'

  # Enter PEM pass phrase:

  # Verifying password - Enter PEM pass phrase:

  # ——

  # 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.

  # Country Name (2 letter code) [AU]:CN

  # State or Province Name (full name) [Some-State]:ZJ

  # Locality Name (eg, city) []:JX

  # Organization Name (eg, company) [Internet Widgits Pty Ltd]:Centeur CA

  # Organizational Unit Name (eg, section) []:HN

  # Common Name (eg, YOUR name) []:MySQL server

  # Email Address []:lypdarling@gmail.com

  #

  # Please enter the following 'extra' attributes

  # to be sent with your certificate request

  # A challenge password []:

  # An optional company name []:
