1.换源
cd /etc/apt/
vim soursec.list

```
deb http://mirrors.163.com/ubuntu/ trusty main restricted universe multiverse

deb http://mirrors.163.com/ubuntu/ trusty-security main restricted universe multiverse

deb http://mirrors.163.com/ubuntu/ trusty-updates main restricted universe multiverse

deb http://mirrors.163.com/ubuntu/ trusty-proposed main restricted universe multiverse

deb http://mirrors.163.com/ubuntu/ trusty-backports main restricted universe multiverse

deb-src http://mirrors.163.com/ubuntu/ trusty main restricted universe multiverse

deb-src http://mirrors.163.com/ubuntu/ trusty-security main restricted universe multiverse

deb-src http://mirrors.163.com/ubuntu/ trusty-updates main restricted universe multiverse

deb-src http://mirrors.163.com/ubuntu/ trusty-proposed main restricted universe multiverse

deb-src http://mirrors.163.com/ubuntu/ trusty-backports main restricted universe multiverse

```

apt-get update && apt-get upgrade

apt-get clear //删除已经更新过的安装包

2.安装ssh
apt-get install ssh

cd /etc/ssh

vim sshd_conf

修改sshd_conf文件使他可以使用root登陆
输入”sudo gedit /etc/ssh/sshd_config”–>回车–>把配置文件中的”PermitRootLogin without-password”加一个”#”号,把它注释掉–>再增加一句”PermitRootLogin yes”–>保存，修改成功。

shell root登陆


3.安装LAMP环境

安装apache
apt-get install apache2
修改安全配置 cd /etc/apache2  vim apache2.conf
（1）关闭列目录
<Directory /var/www/>
        Options Indexes FollowSymLinks//Options FollowSymLinks
        AllowOverride None
        Require all granted
</Directory>
（2）apache2版本信息隐藏

# 解决问题1 Apache响应消息header中的Server带有Apache的版本信息
ServerTokens ProductOnly
# 解决问题2：Apache的错误返回页面中，也包含同样的信息。除了Apache的信息外，还包括ip地址和端口
ServerSignature Off
