[Jenkins] to modify the port number at the Ubuntu jenkins

jenkins installation directory: / var / lib / jenkins
jenkins log directory: /var/log/jenkins/jenkins.log
jenkins default configuration: / etc / default / jenkins

By examining /etc/init.d/jenkins script, we discovered that in fact you need to do two steps:

1. Modify do_start function check_tcp_port command, the port number from 8080 into 8082

[plain]

# Function that starts the daemon/service

do_start()

{

# the default location is /var/run/jenkins/jenkins.pid but the parent directory needs to be created

mkdir `dirname $PIDFILE` > /dev/null 2>&1 || true

chown $JENKINS_USER `dirname $PIDFILE`

# Return

# 0 if daemon has been started

# 1 if daemon was already running

# 2 if daemon could not be started

$DAEMON $DAEMON_ARGS --running && return 1

# Verify that the jenkins port is not already in use, winstone does not exit

# even for BindException

check_tcp_port "http" "$HTTP_PORT" " 8082" || return 1

# If the var MAXOPENFILES is enabled in /etc/default/jenkins then set the max open files to the

# proper value

if [ -n "$MAXOPENFILES" ]; then

[ "$VERBOSE" != no ] && echo Setting up max open files limit to $MAXOPENFILES

ulimit -n $MAXOPENFILES

# --user in daemon doesn't prepare environment variables like HOME, USER, LOGNAME or USERNAME,

# so we let su do so for us now

$SU -l $JENKINS_USER --shell=/bin/bash -c "$DAEMON $DAEMON_ARGS -- $JAVA $JAVA_ARGS -jar $JENKINS_WAR $JENKINS_ARGS" || return 2

}

2. Modify the / etc / default / jenkins file, port 8080 into 8082

Then restart jenkins, check:

[plain]

ps -def | grep java

jenkins 7234 7233 99 11:14 ? 00:00:04 /usr/bin/java -jar /usr/share/jenkins/jenkins.war --webroot=/var/cache/jenkins/war --httpPort=8082 --ajp13Port=-1
