ubuntu安装Jenkins

按照官网文档安装

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

安装后启动报错

确保已经安装java，我的压缩文件安装的java，需要添加软连

# java环境变量配置
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
# 记得添加软连接: ln -s /opt/jdk/bin/java /usr/bin/java

确定端口没有被占用，jenkins默认使用8080

修改端口号

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

将8080改为其他端口重新启动jenkins
