LAMP安全设置

1.设置MySQL密码,删除多余root账号

[root@localhost ~]# mysql -uroot -p
mysql>set password=password("111");
mysql>use mysql;
mysql>delete from `user` where user!="root";
mysql>delete from `user` where user="root" and host!="localhost";
mysql>exit;

2.设置网站访问目录权限

vim /etc/httpd/conf/httpd.conf

ServerSignature off   //禁止显示操作系统的版本
ServerTokens prod   //显示版本号为apache

凡是有Options的全部加上-Index

NameVirtualHost *:80

<VirtualHost *:80>
ServerName 11.22.33.44    #禁止用户通过IP访问网站根目录
<Location />
    Order Allow,Deny
    Deny from all
</Location>
</VirtualHost>

<VirtualHost *:80>
    ServerAdmin webmaster@abc.com
    DocumentRoot /var/www/html/test/
    ServerName www.abc.com
</VirtualHost>

3.配置PHP.ini

vim /etc/php.ini

(1).magic_quotes_gpc = On //对写入数据库的字符串进行过滤处理

(2).display_errors = Off //关闭错误报告

(3).safe_mode = On //避免本地包含、文件打开、命令执行

(4).disable_functions = phpinfo,exec,system,passthru,shell_exec,escapeshellarg
,escapeshellcmd,proc_close,proc_open
//禁用一些系统函数

(5).register_globals = Off //防止变量滥用

(6).expose_php = Off    //禁止显示php版本信息

4.mysql权限配置

mysql>update user set File_priv='N' where User='root'
