linux 基本配置

一、网络设置

vi /etc/stsconfig/network-scripts/ifcfg-eno16777736

BOOTPROTO=none

IPADDR=192.168.10.10

PREFIX=24

GATEWAY=192.168.10.2

DNS1=114.114.114.114

重新网络：systemctl restart network

配置主机名：hostnamectl set-hostname xxx

二、关闭SELINIX 和防火墙

getenforc

setenforce 0

sed -i "s/=enforcing/=disabled/g" /etc/selinux/config

cat /etc/selinux/config

 

systemctl stop firewalld.service

systemctl disable firewalld.service

三、配置yum源

yum install wget

wget http://mirrors.163.com/.help/CentOS7-Base-163.repo

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

cp ./CentOS7-Base-163.repo /etc/yum.repos.d/CentOS-Base.repo

yum clean all

yum makecache

四、安装常用软件

wget http://mirrors.163.com/centos/7.4.1708/extras/x86_64/Packages/epel-release-7-9.noarch.rpm

yum install gcc gcc-g++ make vim bash-completion epel-release

yum install net-tools

 

 

五、配置JAVA环境变量·用文本编辑器打开/etc/profile 

下载jdk：http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

 

在profile文件末尾加入： 

export JAVA_HOME=/usr/share/jdk1.8.0_14 

export PATH=$JAVA_HOME/bin:$PATH 

export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar 

 

cat > /etc/profile.d/mysql.sh << EOF

> export PATH=$PATH:/usr/local/mysql/bin

> EOF

 

cat >> /etc/hosts << EOF

192.168.1.61 docker

192.168.1.62 node1

192.168.1.63 node2

EOF

 

# ssh-keygen -t dsa -f ~/.ssh/id_dsa -N ""

# ssh-copy-id node1

# ssh-copy-id node2

# ssh-copy-id docker
