Linux下安裝支持ssl連接的Mysql

1. 安裝 OpenSSL:

下載 OpenSSL Version 0.9.6 (www.openssl.org)

shell> zcat 0.96l.tar.gz | tar xvf -
shell> ./config
shell> make
shell> make install

2. 安裝 MySQL:

下載 MySQL Version 4.0.14 Source (mysql-4.0.14.tar.gz)

shell> groupadd mysql
shell> useradd -g mysql mysql

shell> gunzip < mysql-VERSION.tar.gz | tar -xvf -
shell> cd mysql-VERSION

shell> ./configure --prefix=/usr/local/mysql --with –openssl --with -vio
shell> make
shell> make install
shell> cp support-files/my-medium.cnf /etc/my.cnf
shell> cd /usr/local/mysql
shell> bin/mysql_install_db --user=mysql
shell> chown -R root .
shell> chown -R mysql var
shell> chgrp -R mysql .

shell> bin/mysqld_safe --user=mysql &

3. 修改mysql密碼及訪問權限　(根據需要。可能造成安全問題)

shell>　cd /usr/local/mysql/bin/
shell>　./mysql -u root –p

mysql>　INSERT INTO mysql.user VALUES ('%','root', PASSWORD('1qw23e'),'Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','','','','',0,0,0,0);

4. 生成SSL證書

DIR=`pwd`/openssl
PRIV=$DIR/private

mkdir $DIR $PRIV $DIR/newcerts
cp /usr/share/ssl/openssl.cnf $DIR
replace ./demoCA $DIR -- $DIR/openssl.cnf

# Create necessary files: $database, $serial and $new_certs_dir
# directory (optional)

touch $DIR/index.txt
echo "01" > $DIR/serial

# Generation of Certificate Authority(CA)
openssl req -new -x509 -keyout $PRIV/cakey.pem -out $DIR/cacert.pem \
-config $DIR/openssl.cnf

Note : if you were requested to enter "PEM pass", please enter different "PEM pass" in the following steps.

# Create server request and key
openssl req -new -keyout $DIR/server-key.pem -out \
$DIR/server-req.pem -days 3600 -config $DIR/openssl.cnf

# Remove the passphrase from the key (optional)
openssl rsa -in $DIR/server-key.pem -out $DIR/server-key.pem

# Sign server cert
openssl ca -policy policy_anything -out $DIR/server-cert.pem \
-config $DIR/openssl.cnf -infiles $DIR/server-req.pem

# Create client request and key
openssl req -new -keyout $DIR/client-key.pem -out \
$DIR/client-req.pem -days 3600 -config $DIR/openssl.cnf

# Remove a passphrase from the key (optional)
openssl rsa -in $DIR/client-key.pem -out $DIR/client-key.pem

# Sign client cert
openssl ca -policy policy_anything -out $DIR/client-cert.pem \
-config $DIR/openssl.cnf -infiles $DIR/client-req.pem

5. 修改選項文件

/etc/my.cnf
[client]
ssl-ca=$DIR/cacert.pem
ssl-cert=$DIR/client-cert.pem
ssl-key=$DIR/client-key.pem
[mysqld]
ssl-ca=$DIR/cacert.pem
ssl-cert=$DIR/server-cert.pem
ssl-key=$DIR/server-key.pem

6. 測試啟動mysql

$DIR 是選項文件my.cnf 的路徑
shell> mysqld --defaults-file=$DIR/my.cnf &
Then invoke a client program using the same option file:
shell> mysql --defaults-file=$DIR/my.cnf

執行以下語句，如果返回以下結果，安裝完全成功

mysql> SHOW VARIABLES LIKE 'have_openssl';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| have_openssl | YES |
+---------------+-------+

7. 啟動MySQL　daemon

/usr/local/libexec/mysqld -u mysql & 　或者　/usr/local/sbin/mysqld
