CentOS Linux Shell

CentOS初始化脚本 CentOS-init.sh

Posted by 移影残风 on January 24, 2019

一键执行：

curl https://yiyingcanfeng.github.io/centos-init.sh | bash

脚本执行后会：

修改yum源
安装一些生产环境必备的软件：
  • OpenJDK 1.8
  • Tomcat 9
  • MySQL 5.7
  • mongodb-org 4
  • Redis 5
  • docker-ce
  • Python36-pip(python3.6会作为依赖被安装)
  • PHP 7.2(Apache httpd会作为依赖被安装)
    配置MySQL

    默认开启远程访问，root默认密码为1111
    如需修改默认密码，执行之前修改脚本中的MYSQL_PASSWORD变量的值即可
    或者执行前先导入MYSQL_PASSWORD变量

export MYSQL_PASSWORD=your_password
将pip源更换成国内源

默认是 http://mirrors.aliyun.com/pypi/simple/

将npm源更换成国内源

默认是 淘宝 NPM 镜像

修改docker镜像源

默认是 https://registry.docker-cn.com

安装一些实用的命令行工具：
  • 通过yum安装的：
bash-completion git wget vim nano yum-utils unar screen lrzsz supervisor iotop iftop jnettop mytop apachetop atop htop ncdu nmap pv net-tools sl lynx links crudini the_silver_searcher tig cloc nload w3m axel tmux mc glances multitail
  • 通过pip安装的：
cheat mycli icdiff you-get lolcat youtube-dl
  • 通过npm安装的：
get-port-cli hasha-cli http-server
安装几个基于命令行的小游戏：
curl https://raw.githubusercontent.com/mydzor/bash2048/master/bash2048.sh -o 2048.sh && chmod 755 2048.sh
./2048.sh
  • 扫雷 
    curl https://raw.githubusercontent.com/feherke/Bash-script/master/minesweeper/minesweeper.sh -o minesweeper.sh && chmod 755 minesweeper.sh
./minesweeper.sh
  • 俄罗斯方块
git clone https://github.com/uuner/sedtris.git
chmod 755 sedtris/*
./sedtris/sedtris.sh
完整脚本:
