补充一下ssl相关资料

1.安装ssl

#wget http://www.openssl.org/source/openssl-1.0.0a.tar.gz
#tar xvzf openssl-1.0.0a.tar.gz

#cd openssl-1.0.0a

#./config shared //用于产生相关.so库文件，nrpe如果用ssl,编译会用到

#make

#make install

2.安装httpd-2.0.50 (以下的方式都是静态绑定ssl)

#tar zxvf httpd-2.0.50.tar.gz

#./configure --prefix=/usr/local/apache2 --enable-so --enable-ssl=static --with-ssl=/usr/local/ssl --enable-mods-shared=all

#make

#make install

ps: 没试过在现有apache里面通过apx增加ssl模块,网上见过隔离出的ssl.conf配置文件，不知道可行否

3.制作证书

可以用来生成ssl所用到的证书。

现在没有这个工具了，只能自己动手生成了，对证书不熟悉的人，有一个工具可以使用：http://www.openssl.org/contrib/ssl.ca-0.1.tar.gz

#cp ssl.ca-0.1.tar.gz /usr/local/apache2/conf

#cd /usr/local/apache2/conf

#tar zxvf ssl.ca-0.1.tar.gz

#cd ssl.ca-0.1

#./new-root-ca.sh (生成根证书)

No Root CA key round. Generating one

Generating RSA private key, 1024 bit long modulus

...........................++++++

....++++++

e is 65537 (0x10001)

Enter pass phrase for ca.key: (输入一个密码)

Verifying - Enter pass phrase for ca.key: (再输入一次密码)

......

Self-sign the root CA... (签署根证书)

Enter pass phrase for ca.key: (输入刚刚设置的密码)

........

........ (下面开始签署)

Country Name (2 letter code) [MY]:CN

State or Province Name (full name) [Perak]:GuangDong//随你喜欢

Locality Name (eg, city) [Sitiawan]:GuangZhou//随你喜欢

Organization Name (eg, company) [My Directory Sdn Bhd]:GDLC//随你喜欢

Organizational Unit Name (eg, section) [Certification Services Division]:GDLC//随你喜欢

Common Name (eg, MD Root CA) []:winson CA//随你喜欢

Email Address []:yu.hanhui@gd-linux.org//随你喜欢

这样就生成了ca.key和ca.crt两个文件，下面还要为我们的服务器生成一个证书：

# ./new-server-cert.sh server (这个证书的名字是server)

......

......

Country Name (2 letter code) [MY]:CN

State or Province Name (full name) [Perak]: GuangDong

Locality Name (eg, city) [Sitiawan]: GuangZhou

Organization Name (eg, company) [My Directory Sdn Bhd]:GDLC

Organizational Unit Name (eg, section) [Secure Web Server]:GDLC

Common Name (eg, www.domain.com) []:localhost

Email Address []:yu.hanhui@gd-linux.org

这样就生成了server.csr和server.key这两个文件。

还需要签署一下才能使用的：

# ./sign-server-cert.sh server

CA signing: server.csr -> server.crt:

Using configuration from ca.config

Enter pass phrase for ./ca.key: (输入上面设置的根证书密码)

Check that the request matches the signature

Signature ok

The Subject‘s Distinguished Name is as follows

countryName :PRINTABLE:‘CN‘

stateOrProvinceName :PRINTABLE:‘JiangSu‘

localityName :PRINTABLE:‘NanJing‘

organizationName :PRINTABLE:‘Wiscom System Co.,Ltd‘

organizationalUnitName:PRINTABLE:‘ACSTAR‘

commonName :PRINTABLE:‘acmail.wiscom.com.cn‘

emailAddress :IA5STRING:‘acmail@wiscom.com.cn‘

Certificate is to be certified until Jul 16 12:55:34 2005 GMT (365 days)

Sign the certificate? [y/n]:y

1 out of 1 certificate requests certified, commit? [y/n]y

Write out database with 1 new entries

Data Base Updated

CA verifying: server.crt <-> CA cert

server.crt: OK

(如果这里出现错误，最好重新来过，删除ssl.ca-0.1这个目录，从解压缩处重新开始。)

下面要按照ssl.conf里面的设置，将证书放在适当的位置。

# chmod 400 server.key

# cd ..

# mkdir ssl.key

# mv ssl.ca-0.1/server.key ssl.key

# mkdir ssl.crt

# mv ssl.ca-0.1/server.crt ssl.crt

然后就可以启动啦！

# cd /usr/local/apache2

# ./bin/apachectl startssl

对于这个提示：

httpd: Could not determine the server‘s fully qualified domain name, using 127.0.0.1 for ServerName

只需要编辑httpd.conf,找到ServerName xxxx这一行，去掉前面的注释即可。
