CentOS settings(持续更新中)

CentOS/RHEL是最流行的服务器操作系统，所以我选择CentOS作为开发部署环境。 本文主要是配置CentOS至中国国内的源并安装常用的开发依赖。

CentOS安装

• 安装过程中网络配置hostname并打开网卡
• 替换yum源

#### centos7
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
curl https://lug.ustc.edu.cn/wiki/_export/code/mirrors/help/centos?codeblock=3 --output /etc/yum.repos.d/CentOS-Base.repo
yum makecache

• 安装vmtools和Development Tools

sudo yum install -y open-vm-tools
reboot

#### 更新系统
sudo yum check-update
sudo yum update

#### 开发环境工具
yum groupinstall 'Development Tools' -y

docker

• centos7的docker安装

sudo yum install -y yum-utils device-mapper-persistent-data lvm2
curl https://download.docker.com/linux/centos/docker-ce.repo --output /etc/yum.repos.d/docker-ce.repo
sudo sed -i 's+download.docker.com+mirrors.ustc.edu.cn/docker-ce+' /etc/yum.repos.d/docker-ce.repo
sudo yum makecache fast
sudo yum install docker-ce docker-ce-cli containerd.io
sudo systemctl enable docker
sudo systemctl start docker

• 修改docker hub地址 /etc/docker/daemon.json 后重启docker服务

{
  "registry-mirrors": ["https://docker.mirrors.ustc.edu.cn/"]
}

python

• python3

sudo yum -y install python-virtualenv
sudo yum -y install python3 python3-pip python3-wheel python3-devel

• 修改python源 $HOME/.config/pip/pip.conf

  mkdir -p /root/.config/pip
  touch $HOME/.config/pip/pip.conf

package-cleanup --oldkernels --count=1
