Centos7 最小化安装

开启网桥

硬盘优先加载操作系统

echo 'nameserver 8.8.8.8' >> /etc/resolv.conf && \
echo 'nameserver 223.5.5.5' >> /etc/resolv.conf && \
echo 'nameserver 223.6.6.6' >> /etc/resolv.conf
           

更新yum

yum -y update
           

安装初始设置工具

1. nano是一个字符终端的文本编辑器
2. vim 是多模式编辑器
3. wget是一个下载文件的工具
4. curl是一个利用URL规则在命令行下工作的文件传输工具
5. ifconfig是linux中用于显示或配置网络设备（网络接口卡）的命令
6. lsof(list open files)是一个列出当前系统打开文件的工具
7. zip、unzip是压缩和解压缩命令工具
8. lrzsz 远程文件上传

yum -y install \
nano \
vim \
wget \
curl \
net-tools \
lsof \
zip \
unzip \
lrzsz \
openssh-server \
iptables-services \
ssh \
cifs-utils \
java-1.8.0-openjdk*
           

启动ssh服务

systemctl start sshd

systemctl enable sshd
           

关闭防火墙

systemctl stop firewalld

systemctl disable firewalld

systemctl stop iptables

systemctl disable iptables
           

编辑网卡配置文件

vi /etc/sysconfig/network-scripts/ifcfg-enp0s3
           

设置固定IP（有则修改 无则添加）

BOOTPROTO="static"
IPADDR=172.16.1.111
GATEWAY=172.16.1.1
NETMASK=255.255.255.0
           

重启网络后重启虚拟机

将除了有ip地址的网络配置信息文件留在/etc/sysconfig/network-scripts目录下，其他网络配置信息文件统统移除

systemctl stop NetworkManager

systemctl disable NetworkManager

systemctl enable NetworkManager-wait-online.service

systemctl restart network
           

再互相ping，正常则centos7最小化安装即完成

linux杀进程

ps -aux | grep workbeeprj-0.0.1-SNAPSHOT.jar
kill -9 pid
           

配置java环境

ls -lrt /usr/bin/java

ls -lrt /etc/alternatives/java

cd /usr/lib/jvm

vi /etc/profile


export JAVA_HOME=/usr/lib/jvm/java-1.8.0
export JRE_HOME=$JAVA_HOME/jre  
export PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib

source /etc/profile
           

查看java版本

java -version
           

Ubuntu镜像源

echo 'deb-src http://mirrors.163.com/ubuntu/ precise main universe restricted multiverse' >> /etc/apt/sources.list && \

echo 'deb-src http://mirrors.163.com/ubuntu/ precise-updates universe main multiverse restricted' >> /etc/apt/sources.list
           

如果发生部分错误 公钥根据提示获取

apt-get update

apt-get install sudo

apt-get update

sudo gpg --keyserver keyserver.ubuntu.com --recv 5523BAEEB01FA116

sudo gpg --export --armor 5523BAEEB01FA116 | sudo apt-key add -

apt-get update

apt-get upgrade -y
