//当前网络获取情况
ìfconfig -a
//手动获取网络
ifup eth0

//自动获取网络
vi /etc/sysconfig/network-scripts/ifcfg-eth0
修改 ONBOOT=no 为 ONBOOT+yes

//重启网络自动获取
service network restart

挂载光盘

mkdir dvd1 dvd2
//挂载光盘iso 到dvd1
mount -o loop -t iso9660 CentOS-6.9-i386-bin-DVD1.iso dvd1

mount -o loop -t iso9660 CentOS-6.9-i386-bin-DVD2.iso dvd2

yum版LNMP环境

yum源的配置
/etc/yum.repo.d/*.repo

cd /etc/yum.repos.d/
//备份线上源
mv CentOS-Base.repo CentOS-Base.repo.bak
//源配置
vi CentOs-Media.repo

baseurl = file://media/dvd1/
                file://media/dvd2/
enabled = 1

//清除yum源环境
yum clean all
//生成yum新环境
yum make cache
//测试安装tree
yum -y install tree
//查找是否包含软件
yum search nginx

安装nginx

nginx官网-documentation-installing nginx- installation on linux
http://nginx.org/en/linux_packages.html

vi /etc/yum.repos.d/nginx.repo
按文档粘贴内容保存
//安装nginx
yum -y install nginx
//查找nginx位置
whereis nginx

cd /etc/nginx/
//nginx.conf: 主配置文件
//conf.d/default.conf: nginx里包裹文件
//开启nginx
nginx
//查看运行状态
ps - aux | grep nginx
//查看防火墙
service iptables status
//关闭防火墙
service iptables stop
//在default.conf中默认访问路径为/usr/share/nginx/html

安装php

//安装php
yum -y install php
//查看安装php版本
php -v
//nginx 需要php-fpm来识别php
yum -y install php-fpm
//启动php-fpm
service php-fpm start
//编辑nginx配置文件
vi /etc/nginx/conf.d/default.conf
找到 pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000

//重启nginx
nginx -s reload
//查看nginx日志文件
cd /var/log/nginx/
access.log 访问日志
error.log 出错日志

安装mysql

//安装mysql服务端和客户端
yum -y install mysql-server mysql
//启动 mysql
service mysqld start
//按提示设置密码
/usr/bin/mysqladmin -u root password '000000'
//重启mysql
service mysqld restart
//打开mysql
mysql -u root -p
//编辑 php mysql 测试代码
//查看 php-fpm 日志
cd /var/log/php-fpm/
//安装php-mysql模块
yum -y install php-mysql
service php-fpm restart

yum 安装优缺点

1.配置yum源，本地源，线上源
2.yum -y install nginx php php-fpm mysql-server mysql php-mysql
3.配置nginx，将php的请求转发给php-fpm
4.出错看日志，搜索

优点：方便便捷，不用考虑包依赖
缺点：不能按需安装， 受源的限制，安装的版本也比较低

优缺点

优点：按需安装版本选择灵活
缺点：依赖包解决繁琐，安装步骤繁琐
