Jenkins容器docker部署springboot项目-问题记录 Jenkins容器docker部署springboot项目-问题记录一、docker容器内不能使用vim解决方案：以root进入容器内docker exec -it -user root jenkins /bin/bash更新软件包apt-get update升级过程可能非常慢，因为是从海外站点拉取镜像，所以我们可以配置一个国内的镜像源，加速镜像拉取更新。备份原文件mv /etc/apt/sources.list /etc/apt/sources.list.bak查看容器中Debian版本cat /etc/issue修改配置sources.list文件根据自己版本修改成对应内容，修改内容参考阿里镜像https://developer.aliyun.com/mirror/debian我容器Debian为11.x版本，修改内容为：cat >/etc/apt/sources.list <<EOF deb http://mirrors.aliyun.com/debian/ bullseye main non-free contrib deb-src http://mirrors.aliyun.com/debian/ bullseye main non-free contrib deb http://mirrors.aliyun.com/debian-security/ bullseye-security main deb-src http://mirrors.aliyun.com/debian-security/ bullseye-security main deb http://mirrors.aliyun.com/debian/ bullseye-updates main non-free contrib deb-src http://mirrors.aliyun.com/debian/ bullseye-updates main non-free contrib deb http://mirrors.aliyun.com/debian/ bullseye-backports main non-free contrib deb-src http://mirrors.aliyun.com/debian/ bullseye-backports main non-free contrib EOF重新执行apt-get update安装vimapt-get install -y vim安装rpmapt-get install rpm -y二、docker容器内vim不能粘贴内容vim右键进入visual模式无法粘贴解决方案vim /usr/share/vim/vim80/defaults.vim修改内容：第70行，在mouse=a的=前面加个-，修改后如下：if has('mouse') set mouse-=a endif三、docker容器内环境配置修改环境变量配置vi /etc/profile新增jdk、mavn环境变量配置# java环境变量 export JAVA_HOME=/jdk/jdk-11.0.10 export JRE_HOME=$JAVA_HOME/jre export PATH=$JAVA_HOME/bin:$PATH export CLASSPATH=./:JAVA_HOME/lib:$JRE_HOME/lib # maven环境变量 export M2_HOME=/maven/apache-maven-3.8.5 export PATH=$PATH:$JAVA_HOME/bin:$M2_HOME/bin重新加载环境变量source /etc/profile检验是否配置成功java -version mvn -v

Vagrantfile安装CentOS虚拟机 一、virtualbox安装1、下载 https://www.virtualbox.org/2、在主板开启CPU虚拟化，自行百度3、安装，直接下一步，选择安装路径。二、安装虚拟机1、下载虚拟系统CentOS7https://app.vagrantup.com/boxes/search Vagrant官方镜像仓库https://www.vagrantup.com/ Vagrant下载2、初始化虚拟系统打开安装好的virtualbox软件，打开window cmd窗口，运行下面命令，即可初始化一个CentOS7系统。初始化之后window用户文件夹夹会多出一个Vagrantfile文件。此时virtualbox界面就会多出一个CentOS系统了。vagrant box add centos/7 CentOS-7-x86_64-Vagrant-2004_01.VirtualBox.box 或 Vagrant init centos/73、启动虚拟机，初始root用户密码vagrant，此时看到virtualbox中的CentOS正在启动。vagrant up4、vagrant其他命令使用vagrant用户链接至CentOS虚拟机，初始root用户密码vagrant。vagrant ssh上传文件vagrant upload source [destination][name][id]更多命令可以访问官网文档5、设置固定ip，默认虚拟机ip是随机的，方式1-修改Vagrantfile，方式2-进入linx系统修改网卡配置信息,下面为修改Vagrantfile改ip：config.vm.network "private_network",ip:"192.168.10.1"6、重启虚拟机vagrant reload7、启动，除了上面的3启动虚拟机，也可以在virtualbox界面选择虚拟机右键开启。8、virtualbox界面还可以设置虚拟机内存大小等信息，更多设置可以查看官网。9、开启ssh登录linux虚拟机。10、进入虚拟机目录cd /etc/sysconfig/network-scripts/配置网卡信息vi ifcfg-eth1修改网卡网关和dns：# The contents below are automatically generated by Vagrant. Do not modify. NM_CONTROLLED=yes BOOTPROTO=none ONBOOT=yes IPADDR=192.168.56.10 NETMASK=255.255.255.0 GATEWAY=192.168.56.1 DNS1=114.114.114.114 DNS2=8.8.8.8 DEVICE=eth1 PEERDNS=no #VAGRANT-END如上加了GATEWAY=192.168.56.1和DNS1=114.114.114.114 、DNS2=8.8.8.8。切换到root用户：su root提示输入root密码，默认密码vagrant。然后重启网卡服务：service network restart11、修改ssh登录，默认未开启。修改linx配置文件vi /etc/ssh/sshd_configPasswordAuthentication no将no改为yes重启ssh服务：service sshd restart现在就可以使用ssh工具进行远程连接了。
