最近遇到一个问题，需要去安装OpenSSL1.0.1c，但是Ubuntu10.04和11.04都只支持0.9.8版本的OpenSSL包。本来想卸载OpenSSL再安装新版本的。我在Ubuntu11.04上引入了12.04的源，直接Upgrade旧版OpenSSL，并安装了几个新版本的依赖包，结果意想不到的事情发生了，我的virtualbox虚拟机软件不能运行了，提示错误，(failed to create virtualbox object!)死活都没法搞定。猜测是由于升级了一些依赖库后发生了故障，至此对预编译之软件包失望至极。

今天闲来无事，决定无论如何要试试源码编译OpenSSL，并和Apache协同工作。我参考了网上的一些文章后开始动手实践。

首先是编译OpenSSL，这个很简单。

./config prefix=/usr/local/openssl && make install

本来我还想卸载旧版本的OpenSSL的，后来放弃了，因为：

这么多软件包，不是逼老子把整个系统都卸载掉么！！！

我使用了几个技巧来处理这个问题

首先是把新版本OpenSSL的安装路径加入$PATH

sudo gvim ~/.bashrc

在文件末尾加上：

PATH="$PATH:/usr/local/openssl/bin:" export PATH

然后保存

将/usr/bin/openssl改名

/usr/bin$ sudo mv openssl openssl0.9.8

这样的就可以在命令行中直接使用新版的OpenSSL了

$ openssl version -a OpenSSL 1.0.1c 10 May 2012 built on: Sun Jul 22 20:43:26 CST 2012 platform: linux-elf options: bn(64,32) rc4(8x,mmx) des(ptr,risc1,16,long) idea(int) blowfish(idx) compiler: gcc -DOPENSSL_THREADS -D_REENTRANT -DDSO_DLFCN -DHAVE_DLFCN_H -Wa,--noexecstack -DL_ENDIAN -DTERMIO -O3 -fomit-frame-pointer -Wall -DOPENSSL_BN_ASM_PART_WORDS -DOPENSSL_IA32_SSE2 -DOPENSSL_BN_ASM_MONT -DOPENSSL_BN_ASM_GF2m -DSHA1_ASM -DSHA256_ASM -DSHA512_ASM -DMD5_ASM -DRMD160_ASM -DAES_ASM -DVPAES_ASM -DWHIRLPOOL_ASM -DGHASH_ASM OPENSSLDIR: "/usr/local/openssl/ssl"

变更include头文件:

/usr/include$ sudo mv openssl openssl0.9.8

/usr/include$ sudo cp -r /usr/local/openssl/include ./

还需要重新编译Apache才能使用新版的OpenSSL

$ ./configure --prefix=/usr/local/apache2.4 --with-layout=Apache

--enable-modulues=most --enable-mods-shared=all --with-mpm=prefork

--with-ssl=/usr/local/openssl

注意最后一句是启用新版OpenSSL的关键

然后就是套路了，make && make install

配置……

然后测试一下，证明已经可以用的一个证据是：

./ab -t 5 -c 100 -n 20000 https://127.0.0.1/index.html This is ApacheBench, Version 2.4 (OpenSSL 1.0.1c 10 May 2012)

看来以后要多用源码安装，少用系统预编译的包，不然可更新软件可真是麻烦呀
