修改网卡

vi /etc/sysconfig/network-scripts/ifcfg-enp0s3


[root@bogon ~]# cat /etc/sysconfig/network-scripts/ifcfg-enp0s3
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=dhcp
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=enp0s3
UUID=e68fb8ab-8ec6-42f1-83b4-bbd9b086dd29
DEVICE=enp0s3
ONBOOT=yes
[root@bogon ~]#

把ONBOOT改成yes

修改固定IP

cat /etc/sysconfig/network-scripts/ifcfg-enp0s3

有可能没有一个字段BOOTPROTO，或者它的值不是static

进行对应的修改：

BOOTPROTO="static" #原值有可能是dhcp

再进行以下新增：

IPADDR=192.168.199.66 #静态IP GATEWAY=192.168.199.1 #默认网关 DNS1="192.168.254.1" #DNS

[root@bogon ~]# cat /etc/sysconfig/network-scripts/ifcfg-enp0s3
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=enp0s3
UUID=e68fb8ab-8ec6-42f1-83b4-bbd9b086dd29
DEVICE=enp0s3
ONBOOT=yes
IPADDR=192.168.8.105
GATEWAY=192.168.8.1
DNS1=192.168.8.1
[root@bogon ~]# 
[root@bogon ~]# service network restart

重启网络

[root@bogon ~]# service network restart

安装python3

先安装wget zlib* （python必须用的）

下载python安装包
[root@bogon ~]# wget https://www.python.org/ftp/python/3.6.3/Python-3.6.3.tgz
[root@bogon ~]# tar -zxvf Python-3.6.3
[root@bogon ~]# yum -y install wget
[root@bogon ~]# yum -y install zlib*
[root@bogon ~]# yum -y install gcc
[root@bogon ~]# mkdir /usr/local/python3
[root@bogon ~]# cd Python-3.6.3/
[root@bogon ~]#./configure --prefix=/usr/local/python3
[root@bogon ~]#make
[root@bogon ~]#make install
[root@bogon ~]#rm /usr/bin/python
[root@bogon python3]# ln -s /usr/local/python3/bin/python3 /usr/bin/python
[root@bogon python3]# python -V
Python 3.6.3

安装pip3（无用，参考）

[root@bogon ~]#wget --no-check-certificate  https://pypi.python.org/packages/source/s/setuptools/setuptools-19.6.tar.gz#md5=c607dd118eae682c44ed146367a17e26
[root@bogon ~]# tar -zxvf setuptools-19.6.tar.gz
[root@bogon ~]# cd setuptools-19.6
[root@bogon setuptools-19.6]# python setup.py build
[root@bogon setuptools-19.6]# python setup.py install
