    Centmin Mod 1.2.3-eva2000.08+ LibreSSL 2.3.3



    LibreSSL 2.3.3 is now the stable release with a few bug and nginx 1.9.12 compatibility fixes for following:

    Centmin Mod 123.08stable and 123.09beta01 Github branches corresponding to Centmin Mod 1.2.3-eva2000.08 stable and Centmin Mod 1.2.3-eva2000.09 beta01 have been updated to default to LibreSSL 2.3.3 for new fresh installs. For existing folks, follow below update instructions.

    Centmin Mod Nginx Update LibreSSL



    For Centmin Mod 1.2.3-eva2000.08 beta03, .08 stable and higher you can update to LibreSSL 2.3.3 via 2 steps.

    Step 1. Updating centmin.sh LIBRESSL_VERSION variable to 2.3.3. Best way is to use centmin.sh menu option 23 submenu option 2 for auto updating Centmin Mod code as outlined at centminmod.com/upgrade.html and at https://community.centminmod.com/threads/new-08-beta-menu-option-updating-centmin-mod-via-git.3084/. That will auto update centmin.sh to latest version which already has LIBRESSL_VERSION='2.3.3' set.

    If you do not have centmin.sh menu option 23 submenu option 1 for git environment setup, then you need to manually update and edit your server copy of centmin.sh at /usr/local/src/centminmod/centmin.sh

    from
    Code:
    # LibreSSL
    LIBRESSL_SWITCH='y'        # if set to 'y' it overrides OpenSSL as the default static compiled option for Nginx server
    LIBRESSL_VERSION='2.2.6'   # Use this version of LibreSSL http://www.libressl.org/
    to
    Code:
    # LibreSSL
    LIBRESSL_SWITCH='y'        # if set to 'y' it overrides OpenSSL as the default static compiled option for Nginx server
    LIBRESSL_VERSION='2.3.3'   # Use this version of LibreSSL http://www.libressl.org/
    or can do it via sed replacement on centmin.sh within centmin mod directory

    Code:
    cmdir
    sed -i "s|LIBRESSL_VERSION='2.2.6'|LIBRESSL_VERSION='2.3.3'|g" centmin.sh
    grep LIBRESSL_VERSION centmin.sh
    Step 2. Then select centmin.sh menu option #4 to upgrade/downgrade Nginx recompile Nginx and specify latest Nginx version i.e. 1.9.12.

    For example after recompile Nginx version output will show built with LibreSSL 2.3.3

    for 123.09 beta01 with NGINXMODULE_ALTORDER=y enabled

    LibreSSL 2.3.3



    You'll find latest LibreSSL 2.3.3 on official site.

    Alternatively, to update Centmin Mod Nginx, read instructions here or below.

    To update your Centmin Mod builds follow instructions at centminmod.com/upgrade.html and respective version threads below:

    Upgrading Centmin Mod Code to Latest Version



    Upgrading Centmin Mod involves 2 parts.
    1. Upgrading the actual Centmin Mod code outlined at Upgrade Centmin Mod - CentminMod.com LEMP Nginx web stack for CentOS This is heart of Centmin Mod where the code is the engine that runs centmin.sh shell based menu and all the automation you're accustomed to.
    2. Upgrade software that Centmin Mod installed or manages. For this part following outline at Upgrade - How to upgrade Centmin Mod. In this case after updating Centmin Mod code, read instructions here and run centmin.sh menu option 4 to recompile Nginx which already has centmin.sh variable updated to 2.3.3
      Code:
      LIBRESSL_VERSION='2.3.3'

    You can tell if your Centmin Mod Nginx is using OpenSSL or LibreSSL via output of SSH command
    Code:
    nginx -V
    If using LibreSSL, built with line will list such
    Code:
    nginx -V
    nginx version: nginx/1.9.12
    built by clang 3.4.2 (tags/RELEASE_34/dot2-final)
    built with LibreSSL 2.3.3
    If using OpenSSL, built with line will list such
    Code:
    nginx -V
    nginx version: nginx/1.9.12
    built by gcc 4.8.5 20150623 (Red Hat 4.8.5-4) (GCC) 
    built with OpenSSL 1.0.2g  1 Mar 2016

    10.1.x
    My Opinion:

    1º - Openssl with chacha patch from Cloudflare
    2º - Libressl
    3º - Openssl without the patch
