配置jenkins过程中遇到的坑

1. 安装gitlab出现502报错，报错内容如下：
   
   502
   
   GitLab is not responding.
   
   Please contact your GitLab administrator if this problem persists
   
   具体安装步骤百度即可，报错原因
   
   1）端口被占用
   
   解决办法：vim /etc/gitlab/gitlab.rb
   
   
   修改gitlab访问地址及端口
   
   2）内存不够
   
   解决办法：
   
   换一个内存够的主机咯
   
2. 配置jenkins无法连接数据源仓库
   
   Command “/usr/local/git/bin/git ls-remote -h – git@xxx:gongdan/workflow.git HEAD” returned status code 128:
   
   stdout:
   
   stderr: Permission denied, please try again.
   
   Permission denied, please try again.
   
   Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).
   
   fatal: Could not read from remote repository.

Please make sure you have the correct access rights

and the repository exists.


出现这种报错原因：

1.由于gitlab所在服务器的git，默认安装的版本较低

解决方法：升级版本

git –version

yum remove -y git

yum -y install gcc perl-ExtUtils-MakeMaker

yum -y install libcurl-devel expat-devel curl-devel gettext-devel openssl-devel zlib-devel

wget https://mirrors.edge.kernel.org/pub/software/scm/git/git-2.9.5.tar.gz

tar -zvxf git-2.9.5.tar.gz

cd git-2.9.5.tar

make prefix=/usr/local/git all

make prefix=/usr/local/git install

make prefix=/usr/local/git all

3.使用maven构建环境



构建后操作，复制jar包到指定位置，执行脚本



脚本内容：

#!/bin/bash
APP_NAME=/usr/local/java/app/workflow/workflow-0.0.1-SNAPSHOT.jar
jar_name=workflow-0.0.1-SNAPSHOT.jar
#拷贝jar包
cpjars(){
    file_path=/root/.jenkins/workspace/workflow/target
    if [ -f "$jar_name" ]
    then
    mv ./$jar_name ./backup/$jar_name.`date +%Y%m%d%H%M%S`
    fi
    cp $file_path/$jar_name .
}
is_exist(){
  pid=`ps -ef|grep $jar_name|grep -v grep|awk '{print $2}'`
  #如果不存在返回1，存在返回0     
  if [ -z "${pid}" ]; then
   return 1
  else
    return 0
  fi
}
#启动方法
start(){
  cpjars
  is_exist
  if [ $? -eq 0 ]; then
    echo "${jar_name} is already running. pid=${pid}"
  else
    nohup java -jar ${jar_name}  >robotcenter.out 2>&1 &
    echo "======${jar_name}已启动===="
  fi
}

#停止方法
stop(){
  is_exist
  if [ $? -eq "0" ]; then
    kill -9 $pid
    echo "======${jar_name}已停止===="
  else
    echo "${jar_name} is not running"
  fi  
}
#输出运行状态
status(){
  is_exist
  if [ $? -eq "0" ]; then
    echo "${jar_name} is running. Pid is ${pid}"
  else
    echo "${jar_name} is NOT running."
  fi
}

#重启
restart(){
  stop
  start
}

#根据输入参数，选择执行对应方法，不输入则执行使用说明
case "$1" in
  "start")
    start
    ;;
  "stop")
    stop
    ;;
  "status")
    status
    ;;
  "restart")
    restart
    ;;

    usage
