SSL / TLS settings for SAP NetWeawer

Tarafından yazılmıştır

A lot of SAP product such as NetWeaver using sapcrypto / commoncrypto library (sapcryptolib.dll or sapcryptolib.so) for SSL / TLS and encryption.

SSL / TLS client configuration.

ssl/client_ciphersuites = 150:PFS:HIGH::EC_P256:EC_HIGH

SSL / TLS server configuration. 

ssl/ciphersuites = 135:PFS:HIGH::EC_P256:EC_HIGH

You need at least 8.4.40 sapcrpytolib for SNI (Server Name Indication) support. Before SNI protocol client request certificate with domain IP instead of domain name. SNI used for hosting multiple site on same port with encryption.

ssl/client_sni_enabled = TRUE

We need updated kernel for using this parameter, details are in this note.

Also you can set these parameters as OS environment variable.

SAPSSL_CLIENT_CIPHERSUITES = 135:PFS:HIGH::EC_P256:EC_HIGH
SAPSSL_CLIENT_SNI_ENABLED = TRUE

Update


If you update some packages, your config files override with new ones. You can find old files with rpm extension in same directory.


Latest Packages


Some linux distributions update their package with delay. IUS is good option for using latest package. You can get IUS package list here and install them with below command.


Install ius rpm package first:


yum install https://centos7.iuscommunity.org/ius-release.rpm


Use u suffix for Installing package from ius repo. For example use below for installing git 2.x:


yum install git2u


Postgres


Download rpm package, check this list for other versions.

wget https://download.postgresql.org/pub/repos/yum/9.6/redhat/rhel-7-x86_64/pgdg-centos96-9.6-3.noarch.rpm

Install package.

rpm -i pgdg-centos96-9.6-3.noarch.rpm

yum install postgresql96-server postgresql96-contrib

/usr/pgsql-9.6/bin/postgresql96-setup initdb


Create db and user.



su postgres

createuser --interactive

createdb -O myuser mydb




Run psql for setting password to new user.



psql

ALTER USER mydbuser WITH PASSWORD 'mynewpass';

\q


Proxy


If you need proxy you can use nginx. You need give permission to nginx for accessing http resources.


setsebool httpd_can_network_connect true -P


Check nginx.log with


tail -10f /var/log/nginx/error.log


php & php-fpm


Use IUS for latest release, php72u.


Permissions overwritten after update, check /var/lib/php/fpm permissions.
