干货集锦（一） centos7基本环境安装及shell脚本分享
搭建centos环境
从接触linux环境以来就一直想从零搭建一个完整的Centos开发生产环境并记录下来，知道最近这段时间才正好自己部署新的东西，然后得空搭了一套 完整的lnmp环境并写成了一个脚本能够一键搭建。
步骤
首先需要一个极简的centos7环境
针对这一步，我安装了最小化的centos7，并配置网卡，更改虚拟机设置，配置桥接网络，更改centos7默认的网卡设置。
cat /etc/sysconfig/network-scripts/ifcfg-ens33
vi /etc/sysconfig/network-scripts/ifcfg-ens33
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=ens3
UUID=9d18ab7f-c2ad-42a8-915c-914755bfbd51
ONBOOT=yes
IPADDR=192.168.0.212
NETMASK=255.255.255.0
GATEWAY=192.168.0.1
DNS1=192.168.0.1
其次，就该配置yum源了
这次我的yum源是跟我们的运维小哥要的一份，这个我会分享到百度网盘
# 链接：https://pan.baidu.com/s/18JRN0HGYwtY3wDzcU1exmw 密码：coxr
#在删除 /etc/yum.repo.d/中所有的文件之前下载一个 lrzsz 让其能下载刚刚从云盘拿下来的文件
#之后执行
mv rpm-gpg-key-epel-7 RPM-GPG-KEY-EPEL-7
\cp RPM-GPG-KEY-* /etc/pki/rpm-gpg/
yum clean all
这样，yum源就配置完成了。

最后就执行lnmp的脚本就完事大吉了
暂且先把脚本放到这里，若之后有不妥再换成文件分享
