CentOS7初使用

1，配置静态IP

1，虚拟机设置为桥接
2，ipconfig查看win物理机的ip，网关，子网掩码，DNS
3，vi /etc/sysconfig/network-scripts/ifcfg-ens33(ens33每个人可能不一样)
     修改行BOOTPROTO=static        #修改成static
     修改行ONBOOT=yes     #修改成yes

     添加行IPADDR=192.168.1.100  #物理机同一网段的IP
     添加行NETMASK=255.255.255.0   #物理机一样的子网掩码
     添加行GETWAY=192.168.1.1  #物理机一样的网关
     添加行DNS1=192.168.1.1  #物理机一样的DNS 一般为路由器的地址
4，添加网关地址：vi /etc/sysconfig/network
     NETWORKING=yes
     HOSTNAME=起个名字
     GATEWAY=192.168.1.1  #物理机一样的网关
5，添加DNS  vi /etc/resolv.conf
     # Generated by NetworkManager
     nameserver 192.168.1.1 #和物理机一样
6，重启 service network restart

2，配置yum源

cd  /etc/yum.repos.d/
wget  http://mirrors.aliyun.com/repo/Centos-7.repo
mv  CentOS-Base.repo CentOS-Base.repo.bak
mv Centos-7.repo CentOS-Base.repo
yum clean all
yum makecache
yum update

3，安装python3

yum install gcc openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel libffi-devel tk-devel wget curl-devel
cd /tmp
wget https://www.python.org/ftp/python/3.7.2/Python-3.7.2.tgz
tar -zxvf Python-3.7.2.tgz
mkdir /usr/local/python3
Python-3.7.2/configure --prefix=/usr/local/python3/
make
make install
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
