This article mainly explains "how to install and configure the new version of the source code without uninstalling the existing OpenSSL". The content of the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "how to install and configure the new version of OpenSSL+Apache without uninstalling the existing OpenSSL".

Recently there was a problem with the need to install OpenSSL1.0.1c, but both Ubuntu10.04 and 11.04 only support version 0.9.8 of the OpenSSL package. I wanted to uninstall OpenSSL before installing the new version. I introduced the 12.04 source on Ubuntu11.04, directly Upgrade the old version of OpenSSL, and installed several new versions of the dependency package. As a result, something unexpected happened and my virtualbox virtual machine software could not run, prompting an error, (failed to create virtualbox object!) I can't handle life or death. The guess is that there was a failure after upgrading some dependent libraries, so I was extremely disappointed with the precompiled software package.

Having nothing to do today, I decided to try to compile OpenSSL with source code and work with Apache anyway. After referring to some articles on the Internet, I began to practice.

The first step is to compile OpenSSL, which is very simple.

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

I originally wanted to uninstall the old version of OpenSSL, but then I gave up because:

With so many software packages, didn't you force me to uninstall the whole system!

I used several techniques to deal with the problem.

The first step is to add the installation path of the new version of OpenSSL to $PATH

Sudo gvim / .bashrc

Add the following at the end of the file:

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

And then save.

Rename / usr/bin/openssl

/ usr/bin$ sudo mv openssl openssl0.9.8

In this way, you can use the new version of OpenSSL directly from the command line.

$openssl version-an OpenSSL 1.0.1c 10 May 2012 built on: Sun Jul 22 20:43:26 CST 2012 platform: linux-elf options: bn (64jue 32) rc4 (8xmemmmx) 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-DSHA256_ASM-DSHA512_ASM-DMD5_ASM-DRMD160_ASM-DAES_ASM-DVPAES_ASM-DWHIRLPOOL_ASM-DGHASH_ASM OPENSSLDIR: "/ usr/local/openssl/ssl"

Change the include header file:

/ usr/include$ sudo mv openssl openssl0.9.8

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

You also need to recompile Apache to use the new version of 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

Note that the last sentence is the key to enabling the new version of OpenSSL

And then there's the routine, make & & make install.

Configure.

Then test it, and one of the evidence to prove that it can be used is:

. / 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)

It seems that we should use more source code installation and less system precompiled packages in the future, otherwise the updatable software will be really troublesome.
