Untuk melakukan instalasi SSL di sistem lokal dengan Fedora 18 bisa menggunakan OpenSSL. Tetapi SSL yang kita buat akan menampilkan untrusted pada browser, karena ini adalah percobaan di sistem lokal jadi tidak terlalu bermasalah. Web server yang kita gunakan adalah Apache.
Instalasi
Buka terminal, lalu login sebagai root
su -
atau
su rootinstall Apache, mod_ssl dan openssl
yum install httpd mod_ssl openssl
untuk mempermudah tutorial kali ini, kita akan menggunakan konfigurasi bawaan dari apache tanpa menggunakan virtualhost.
Konfigurasi SSL
Buat sebuah folder ssl di /var/www/html lalu berpindah ke folder ssl tersebut
mkdir /var/www/html/ssl ; cd /var/www/html/ssl
Generate key dan CSR (Certificate Signing Request) dengan bantuan OpenSSL
openssl req -new -x509 -days 365 -nodes -out local.csr -keyout local.key
contoh pengisian untuk perintah diatas
Generating a 2048 bit RSA private key ....................................................................................+++ ....................................................+++ writing new private key to 'local.key' ----- You are about to be asked to enter information that will be incorporated into your certificate request. What you are about to enter is what is called a Distinguished Name or a DN. There are quite a few fields but you can leave some blank For some fields there will be a default value, If you enter '.', the field will be left blank. ----- Country Name (2 letter code) [XX]:ID State or Province Name (full name) []:Sumatera Utara Locality Name (eg, city) [Default City]:Berastagi Organization Name (eg, company) [Default Company Ltd]:Jaranguda Organizational Unit Name (eg, section) []:SSL Common Name (eg, your name or your server's hostname) []:localhostku Email Address []:admin@localhostku
Buka file /etc/httpd/conf.d/ssl.conf dengan editor favorite anda, disini saya akan menggunakan nano
nano /etc/httpd/conf.d/ssl.conf
Ubah bagian
#DocumentRoot "/var/www/html" #ServerName www.example.com:443 #SSLCertificateFile /etc/pki/tls/certs/localhost.crt #SSLCertificateKeyFile /etc/pki/tls/private/localhost.key
menjadi
DocumentRoot "/var/www/html" ServerName localhost:443 SSLCertificateFile /var/www/html/ssl/local.csr SSLCertificateKeyFile /var/www/html/ssl/local.key
sekarang jalankan Apache
service httpd start
bila tidak ada error yang muncul, buka browser anda lalu arahkan ke https://localhost bila muncul error seperti gambar dibawah ini (tampilan pada browser Google Chrome)
klik saja Proceed anyway
Mengatasi Error
Bila muncul error
[Sun Jan 27 01:48:14.001376 2013] [ssl:emerg] [pid 3905] AH02312: Fatal error initialising mod_ssl, exiting.

coba check certificate yang tadi anda buat dengan perintah
openssl x509 -noout -text -in local.csr
bila muncul pesan seperti dibawah ini, ganti certificate anda dengan yang baru, dengan menjalankan perintah di awal tutorial ini
unable to load certificate 139847712094048:error:0906D06C:PEM routines:PEM_read_bio:no start line:pem_lib.c:696:Expecting: TRUSTED CERTIFICATE
