1、网卡配置

vi /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0
HWADDR=00:0C:29:6C:BB:E6
NM_CONTROLLED="yes"
ONBOOT=yes
PEERDNS=yes
BOOTPROTO=static
IPADDR=192.168.0.8
NETMASK=255.255.255.0
GATEWAY=192.168.0.1
DNS1=10.168.0.105
DNS2=20.16.0.20

注：重点配置最后6行，静态分配ip，ip地址，子网掩码、网关，DNS。

记得要重启network服务！！！

service network restart

2、DNS配置

vi /etc/resolv.conf
nameserver xxx.xxx.xxx.xxx

注：xxx.xxx.xxx.xxx是网关ip，可以配置多个。（如果第1步中配置了DNS，则会自动添加到该文件中）

 

3、安装源配置

yum install wget -y && mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
yum clean all
yum makecache
yum update

 

4、第三方安装源配置

 

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

此命令安装完成之后就可以使用yum安装nginx、iftop等第三方包了

安装mysql5.6

rpm -Uvh http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
yum repolist enabled | grep "mysql.*-community.*"
yum -y install mysql-community-server
