換源，安裝ssh,lamp

1.換源
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 //刪除已經更新過的安裝包

2.安裝ssh
apt-get install ssh

cd /etc/ssh

vim sshd_conf

修改sshd_conf文件使他可以使用root登陸
輸入”sudo gedit /etc/ssh/sshd_config”–>回車–>把配置文件中的”PermitRootLogin without-password”加一個”#”號,把它註釋掉–>再增加一句”PermitRootLogin yes”–>保存，修改成功。

shell root登陸


3.安裝LAMP環境

安裝apache
apt-get install apache2
修改安全配置 cd /etc/apache2  vim apache2.conf
（1）關閉列目錄
<Directory /var/www/>
        Options Indexes FollowSymLinks//Options FollowSymLinks
        AllowOverride None
        Require all granted
</Directory>
（2）apache2版本信息隱藏

# 解決問題1 Apache響應消息header中的Server帶有Apache的版本信息
ServerTokens ProductOnly
# 解決問題2：Apache的錯誤返回頁面中，也包含同樣的信息。除了Apache的信息外，還包括ip地址和端口
ServerSignature Off
