lighttpd

   Posted by: admin   in Mẹo vặt của hiếu râu

https://www.vultr.com/docs/how-to-install-lighttpd-llmp-stack-on-centos-6

Installing PHP

Install PHP using yum.

yum install lighttpd-fastcgi php-fpm

Configure PHP-FPM user settings.

vi /etc/php-fpm.d/www.conf

We must add the following lines to the either the top or bottom of the configuration:

user = lighttpd

group = lighttpd

Make PHP-FPM start on boot.

php-fpm on

Start PHP-FPM.

service php-fpm start

Configure php.ini.

vi /etc/php.ini

Remove the commenting on the following line.

cgi.fix_pathinfo=1

Tell Lighttpd that PHP exists on this server.

vi /etc/lighttpd/modules.conf

Add the following line.

include “conf.d/fastcgi.conf”

Now we must tell PHP to listen on port 9000 (Lighttpd will send PHP requests there). Using your favorite text editor, edit the fastcgi configuration.

vi /etc/lighttpd/conf.d/fastcgi.conf

At the top of the configuration, add the following lines of code.

fastcgi.server += ( “.php” =>

((

“host” => “127.0.0.1″,

“port” => “9000″,

“broken-scriptfilename” => “enable”

))

)

Restart PHP-FPM and Lighttpd for our changes to take effect.

service php-fpm restart

service lighttpd restart

- ipsec vpn

confidential - encryption - symmectric RC4 DES 3DES AES blowfish , asymmectric public key RSA DH ( groups 12514 )

integrity - hash MD5 SHA1 SHA2 ( sender data+hash, receiver data+hash = hash )

authentication - HMAC ( hashed mess authen code ) Diffie-Hellman algorithm ( DH groups 125 )

Step1 established IKE (500/UDP)- phase 1 : proposals (encrypt,hash,authen,DH groups)- policy (main/aggressive, preshared key)- gateway (IP,interface) - phase 2 : quick mode - proposal ( ESP/AH , hmac ) - policy (PFS reasign DH groups) - vpn ( tunnel/transport mode)

Step 2 : process traffic - transport mode ( insert ipsec header before payload ) vs tunnel mode ( new header packed the original + trail ) ; AH (51,intefrity,authen,antireplay) vs ESP (50 , integrity,authen,antireplay,confidential )

==============================

Phase 1

+ proposal : auth-algo (md5,sha1/256) auth-method ( preshared / DSARSA key) encrypt-algo (DES,3DES,AES) dh-group (12514) lifetime ( 180s - 1day)

+ policy : proposal ( F1_PRO ) preshared-key (”pass123″)/certificate(DSARSA) mode (main/aggresive)

+ gateway : policy ( F1_POL) address (remote_ip) external interface (ge-0/0/0)

Phase 2

+ proposal : authen-algo (HMAC-md5/sha1256) encrypt (DES,3DES,AES) lifetime, protocol (ESP/AH)

+ policy : proposal (F2_PRO) PFS key (group12514)

+ vpn : bind-interface (st0.1) establishedtunnel ( immediate ) ike gateway (F1_GW) ike ipsec-pol (F2_POL)
