Building Apache HTTP Server

###Building Apache Http Web Server

Apache HTTP Web Server is available on RHEL 7.1/6.6 or SLES 12/11 or Ubuntu 16.04. Should you require a different version from those listed below you will need to build it.

• RHEL 7.1 has 2.4.6
• RHEL 6.6 has 2.2.15
• SLES 12 has 2.4.10
• SLES 11.3 has 2.2.12
• Ubuntu 16.04 has 2.4.18

The Apache HTTP web server can be built for Linux on z Systems running RHEL 7.1/6.6 or SLES 12/11 or Ubuntu 16.04 by following these instructions. Version 2.4.20 has been successfully built & tested this way.

General Notes:

i) When following the steps below please use a standard permission user unless otherwise specified.

ii) A directory /<source_root>/ will be referred to in these instructions, this is a temporary writeable directory anywhere you'd like to place it

iii) Where the instructions refer to 'vi' you may, of course, use an editor of your choice

#Building Apache HTTP Web Server

1. Install build dependencies

   For RHEL 7.1 & 6.6

    sudo yum install git openssl openssl-devel gcc libtool autoconf make pcre pcre-devel libxml2 libxml2-devel expat-devel which wget tar
   

   For SLES 12

    sudo zypper install git openssl openssl-devel gcc libtool autoconf make pcre pcre-devel libxml2 libxml2-devel libexpat-devel wget tar
   

   For SLES 11

    sudo zypper install git gcc libtool autoconf make pcre pcre-devel libxml2 libxml2-devel libexpat-devel wget tar
   

   For Ubuntu 16.04

    sudo apt-get install git python openssl gcc autoconf make libtool-bin libpcre3-dev libxml2  libexpat1 libexpat1-dev wget tar 
   

2. Build Openssl 1.0.2 (SLES 11 Only)

    cd /<source_root>/
    wget ftp://openssl.org/source/openssl-1.0.2h.tar.gz
    tar zxf openssl-1.0.2h.tar.gz
    cd openssl-1.0.2h
    ./config --prefix=/usr --openssldir=/etc/ssl --libdir=lib shared zlib-dynamic
    make
    sudo make install		
   

3. Build Libtool (SLES 11 & RHEL 6.6 Only)

   SLES 11 and RHEL 6.6 has an older version of libtool available. Apache HTTP Server needs a later version of libtool.

    cd /<source_root>/
    wget http://ftpmirror.gnu.org/libtool/libtool-2.4.6.tar.gz
    tar -xvf libtool-2.4.6.tar.gz
    cd libtool-2.4.6
    ./configure
    make
    sudo make install
   

4. Extract Apache HTTP source code (and supporting packages)

    cd /<source_root>/
    git clone https://github.com/apache/httpd.git 
    cd httpd
    git checkout 2.4.20
    cd srclib
    git clone https://github.com/apache/apr.git
   

5. Build Apache Portable Runtime

    cd apr
    ./buildconf 
    ./configure
    make
    sudo make install
   

6. Build and Install Apache HTTP Server

    cd /<source_root>/httpd
    ./buildconf
    ./configure --prefix=<build-location>
    make
    sudo make install
   

   Note: Skipping the --prefix results in Apache httpd being installed in the default location.

7. Verification

   Note: All the following commands may require sudo depending on the <build-location> specified

   Update your configuration as necessary

   vi <build-location>/conf/httpd.conf
   

   Verify the configuration and start the server

   <build-location>/bin/apachectl configtest
   <build-location>/bin/apachectl -k start
   

   Note: If <build-location> is the prefix you specified, ensure that in /conf/httpd.conf file, values for User and Group fields are same as that of <build-location>. Else, it will display forbidden(403) error in the browser.

   Test the webserver

   <build-location>/bin/apachectl -k stop
   

   Note: <build-location> is the prefix you specified on step 5 - if you didn't specify a prefix it should be installed to /usr/local/apache2
