Question

linux中openssl安装需要哪些软件包

Answer 1

安装环境：

操作系统：RedHat 12.0
OpenSSL Version:openssl-0.9.8l

Download

安装包(Linux source) : openssl-0.9.8l.tar.gz（or the latest version of openssl）
下载地址：http://www.openssl.org/source/
在linux下解压缩下载到的安装包，命令如下.....
tar -xzf openssl-xxx.tar.gz
Our Configuration

Install to : /usr/local/ssl
Module type : dynamically and staticly loaded modules, *.so *.a
Build Instructions

Configure

.../openssl-0.9.8l]# ./config --prefix=/usr/local/ssl-0.9.8l shared zlib-dynamic enable-camellia

--prefix=/usr/local/ssl-0.9.8l
[this is the installation location; default is '/usr/local/ssl' -- which we will symlink]
shared
[in addition to the usual static libraries, create shared libraries]
zlib-dynamic
[like "zlib", but has OpenSSL load the zlib library dynamically when needed]
enable-camellia
[enables the symmetric cipher 'Camellia' (128-bit, 192-bit, 256-bit key versions), which is now available for royalty-free use]
display guess on system made by './config'...

.../openssl-0.9.8l]# ./config -t

Build and Install

.../openssl-0.9.8l]# make depend
[step required since extra cipher was enabled]
.../openssl-0.9.8l]# make
.../openssl-0.9.8l]# make test
.../openssl-0.9.8l]# make install
Symlink

Form symlink from '/usr/local/ssl-0.9.8l' to '/usr/local/ssl'（...]代表“/usr/local/”）

...]# cd /usr/local
/usr/local]# ln -s ssl-0.9.8l ssl
Update the Run-time Linker

ld.so.cache will need to be updated with the location of the new OpenSSL shared libs: libcrypto.so.0.9.8 and libssl.so.0.9.8

Sometimes it is sufficient to just symlink or copy these two files to /lib, but we recommend you follow these instructions instead.

Edit /etc/ld.so.conf, add to paths...（修改效果如下图1,当然也可以直接在/etc/ld.so.conf.d文件夹下再创建一个.conf文件，把/usr/local/ssl/lib拷贝到里面，另外也可以在现有的.conf文件中添加这个路径，反正ld.so.conf中包含了这个文件夹下的所有.conf文件）
