Detailed description of installing the OpenSSL installation graphic method under Linux (CENTOS7)

OpenSSL is an open source SSL technology, because I need to use PHP-related features, need to get HTTPS files so I have to install this thing, below I have collated two kinds of OpenSSL installation configuration method.

Installation Environment:

Operating system: CENTOS7 quiet

OpenSSL version:openssl-1.0.2j.tar.gz

The current version of the latest SSL address is http://www.openssl.org/source/openssl-1.0.2j.tar.gz

1. Place the downloaded compressed package in the root directory,

2, under the folder decompression, command: Tar-xzf openssl-1.0.2j.tar.gz, get openssl-1.0.2j folder

3. Enter the extracted directory: CD openssl-1.0.2j

4, set the OpenSSL installation, (--prefix) parameters for the installation of the directory, that is, the installed files will appear in this directory:

Execute command:./config--prefix=/usr/local/openssl

5. Execute the order./config-t

6. Execute make to compile OpenSSL

Here if the following error occurs

MAKE[1]: Gcc:command not found angry

Surf the internet to find out I installed the CentOS7 in the GCC compiler

Ensure the system network unblocked, execute the command yum-y install GCC (note, must forget the smooth, otherwise not installed)

7. Installing Openssl:make Install

8. Execute the following command

?

12	[[email protected] /]# cd /usr/local[[email protected] local]# ldd /usr/local/openssl/bin/openssl

A message similar to the following will appear:

9. View the path

?

1	...]# which openssl

View version

?

1	...]# openssl version

Ways to uninstall old versions of OpenSSL

12	apt-get purge opensslrm-rf /etc/ssl#删除配置文件
