ubuntu安裝Jenkins

按照官網文檔安裝

https://jenkins.io/zh/doc/book/installing/

安裝後啓動報錯

確保已經安裝java，我的壓縮文件安裝的java，需要添加軟連

# java環境變量配置
export JAVA_HOME=/opt/jdk
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH
# 記得添加軟連接: ln -s /opt/jdk/bin/java /usr/bin/java

確定端口沒有被佔用，jenkins默認使用8080

修改端口號

sudo vim /etc/default/jenkins

HTTP_PORT=8080

且

 sudo vim /etc/init.d/jenkins

o_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" "$HTTP_PORT" "8080" "$HTTP_HOST" "0.0.0.0" || return 2

將8080改爲其他端口重新啓動jenkins
