系统初始化相关
更换yum源仓库
cd /etc/yum.repos.d/
mkdir repo.bak
mv *.repo repo.bak/
wget -O CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
wget -O CentOS-Base.repo http://mirrors.163.com/.help/CentOS7-Base-163.repo
yum install -y epel-release
yum clean all
yum repolist
命令别名设置 vim ~/.bashrc # 本人常用
alias ='PS1="\[\e[1;30m\][\u@\h \W]\\$ \[\e[0m\]"'
alias ='PS1="\[\e[1;31m\][\u@\h \W]\\$ \[\e[0m\]"'
alias ='PS1="\[\e[1;32m\][\u@\h \W]\\$ \[\e[0m\]"'
alias ='PS1="\[\e[1;33m\][\u@\h \W]\\$ \[\e[0m\]"'
alias ='PS1="\[\e[1;34m\][\u@\h \W]\\$ \[\e[0m\]"'
alias ='PS1="\[\e[1;35m\][\u@\h \W]\\$ \[\e[0m\]"'
alias ='PS1="\[\e[1;36m\][\u@\h \W]\\$ \[\e[0m\]"'
alias cl='clear'
alias df='df -h'
alias ll='ls -lh'
alias lld='ls -lhd'
alias jjar="java -jar $@"
alias ipa="ip a" alias cdnet="cd /etc/sysconfig/network-scripts/"
alias lsnet="ls /etc/sysconfig/network-scripts/"
alias yin="yum install -y"
alias yre="yum remove -y"
alias ls='ls --color=auto'
alias cl="clear"
alias lld="ll -d"
alias df="df -h"
alias du="du -h"
alias dus="du -sh"
alias dft="df -hT"
alias pp="ping -c 2 8.8.8.8" # 退出保存
最后需要source ~/.bashrc 即可
以上都是我安装完系统后第一步需要做的，日后用起来很方便
