Installation of OpenSSL in Linux under the whole process

Chapter I.

1,: http://www.openssl.org/source/next a new version of OpenSSL, I am under the version is: openssl-1.0.0e.tar.gz

1.0.1G source package can be obtained by #wget http://www.openssl.org/source/openssl-1.0.1g.tar.gz

2. In the downloaded GZ directory, execute with command: TAR-XZF openssl-openssl-1.0.0e.tar.gz

3. Enter the extracted directory: openssl-1.0.0e [...] #cd openssl-1.0.0e

4, [... openssl-1.0.0e]#./config--prefix=/usr/local/openssl

5[...../openssl-1.0.0e]#./config-t

6[...../openssl-1.0.0e]# make Depend

7[...../openssl-1.0.0e]# cd/usr/local

8/usr/local]# ln-s OpenSSL SSL

9 in the last side of the/etc/ld.so.conf file, add the following:

/usr/local/openssl/lib

10...]# Ldconfig

11 Add OPESSL Environment variables:

In the last line of etc/'s profile, add:

Export Openssl=/usr/local/openssl/bin

Export path= $OPENSSL: $PATH: $HOME/bin

12 exit the command screen and log in again.

13, above OpenSSL installation is complete, the following for some inspection.

14 perform the following in turn:

[Email protected]/]# cd/usr/local

[Email protected] local]# Ldd/usr/local/openssl/bin/openssl

A message similar to the following will appear:

Linux-vdso.so.1 = (0x00007fff3bc73000)
libdl.so.2 =/lib64/libdl.so.2 (0x00007fc5385d7000)

Chapter II

Upgrade OpenSSL to version 1.0.1g

1. Get 1.0.1g source package via #wget http://www.openssl.org/source/openssl-1.0.1g.tar.gz

2. Installing OpenSSL

#tar ZXVF openssl-1.0.1g.tar.gz
#cd openssl-1.0.1g
#./config shared zlib
#make
#make Install
Mv/usr/bin/openssl/usr/bin/openssl. OFF
Mv/usr/include/openssl/usr/include/openssl. OFF
#cd/usr/bin

Ln-s/usr/local/ssl/bin/openssl OpenSSL

#cd/usr/include

Ln-s/usr/local/ssl/include/openssl OpenSSL

3. Configure the library file search path

#echo "/usr/local/ssl/lib" >>/etc/ld.so.conf
#ldconfig-V

4. Check the OpenSSL version number to verify that the installation is correct

#openssl version-a

You can see that the 1.0.1g version is a good one.
