CentOS7最小化安装的配置

网卡

  1. 查看网卡信息
# ip addr
1: lo:  mtu 65536 qdisc noqueue state UNKNOWN qlen 1
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: eth0:  mtu 1500 qdisc mq state UP qlen 1000
    link/ether 00:15:5d:02:17:08 brd ff:ff:ff:ff:ff:ff
    inet 192.168.2.24/24 brd 192.168.2.255 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::2ef0:7026:4c6d:a05e/64 scope link 
       valid_lft forever preferred_lft forever
  1. 修改网卡配置
# vi /etc/sysconfig/network-scripts/ifcfg-eth0
TYPE="Ethernet"
PROXY_METHOD="none"
BROWSER_ONLY="no"
BOOTPROTO="static"
DEFROUTE="yes"
IPV4_FAILURE_FATAL="no"
IPV6INIT="yes"
IPV6_AUTOCONF="yes"
IPV6_DEFROUTE="yes"
IPV6_FAILURE_FATAL="no"
IPV6_ADDR_GEN_MODE="stable-privacy"
NAME="eth0"
UUID="c6a89e79-daa5-42e4-b013-2731994eb7e3"
DEVICE="eth0"
ONBOOT="yes"
IPADDR="192.168.2.24"
PREFIX="24"
GATEWAY="192.168.2.1"
DNS1="202.96.128.86"
IPV6_PRIVACY="no"
  1. 重启网卡
# systemctl restart network

SSH

  1. 修改sshd配置文件
# vi /etc/ssh/sshd_config
  1. CentOS7默认已启用SSH

文件上传和下载

  1. xshell
# yum -y install lrzsz
  1. ftp
# yum -y install vsftpd
# vi /etc/vsftpd/vsftpd.conf
anonymous_enable=NO
local_enable=YES
write_enable=YES
local_umask=022
chroot_local_user=YES
chroot_list_enable=YES
chroot_list_file=/etc/vsftpd/chroot_list
userlist_enable=NO
userlist_deny=NO

chroot_list 添加 root
去掉/etc/vsftpd/ftpusers中的root

Java安装

  1. 下载java,并上传到/home目录下
  2. 解压并移到/usr/local/java
# tar -zxvf jdk-9.0.1_linux-x64_bin.tar.gz
# mv jdk-9.0.1 /usr/local/java
  1. 配置环境变量
# vi /etc/profile
export JAVA_HOME=/usr/local/java
export JRE_HOME=/usr/local/java/jre
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$JAVA_HOME/bin:$PATH
# source /etc/profile
