Getting Client IP Behind the Aws ELB (Http/Http Mode)

We need to add the Following Logformat to get the clients IP.

We use the X-Forwarded-For entry in the apache configuration to get it done.

# The following directives define some format nicknames for use with
# a CustomLog directive (see below).
#
LogFormat "\"%{X-Forwarded-For}i\" %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined_new
#....

#...
#
# START_HOST example.com

    ServerName example.com
    DocumentRoot "/var/www/example.com/html"

        Options Includes FollowSymLinks
        AllowOverride All
        Order allow,deny
        Allow from all

    CustomLog /var/www/logs/example.com/access_log combined_new
    ErrorLog /var/www/logs/example.com/error_log

Jenkins Starting issue.

Issue with starting
===================
Note: if you get the following error message, ensure that Java has been installed:
Starting jenkins (via systemctl):  Job for jenkins.service failed. See 'systemctl status jenkins.service' and 'journalctl -xn' for details                                            [FAILED]


Check for the tmp directory and if the noexec is enabled on the /tmp, try disabling it.

mount -o remount,exec /tmp

Other way around is by selecting another tmp directory

Edit /etc/sysconfig/jenkins
JENKINS_JAVA_OPTIONS="-Djava.awt.headless=true -Djava.io.tmpdir=$JENKINS_HOME/tmp"

We can get the Jenkins from URL
