centos7.6LAMP配置(三)

一.配置防盗链:

编辑虚拟主机配置文件:
[root@ligenkelong ~]# vim /usr/local/apache2.4/conf/extra/httpd-vhosts.conf
增加如下配置:


    SetEnvIfNoCase Referer "http://111.com" local_ref    #白名单
    SetEnvIfNoCase Referer "192.168.247.1" local_ref   #白名单
    #SetEnvIfNoCase Referer "^$" local_ref   #全部白名单
         #匹配的文件类型
        Order Allow,Deny     
        Allow from env=local_ref
    


[root@ligenkelong ~]# /usr/local/apache2.4/bin/apachectl -t

[root@ligenkelong ~]# /usr/local/apache2.4/bin/apachectl graceful

测试:
curl -e参数定义referer ,一定要以http://开头
[root@ligenkelong ~]# curl -e “http://192.168.247.1” -x127.0.0.1:80 111.com/qq.png -I
HTTP/1.1 200 OK
[root@ligenkelong ~]# curl -e “http:www.qq.com” -x127.0.0.1:80 111.com/qq.png -I
HTTP/1.1 403 Forbidden

二.访问控制:

  1. 限制ip访问:
    编辑虚拟主机配置文件:

[root@ligenkelong ~]# vim /usr/local/apache2.4/conf/extra/httpd-vhosts.conf

     #针对该目录做访问限制
    Order deny,allow  #定义控制顺序,哪个在前面就先匹配哪个规则
    Deny from all
    Allow from 127.0.0.1
    Allow from 192.168.247.1

测试:

[root@ligenkelong ~]# curl -x127.0.0.1:80 -I 111.com/admin/index.php 
HTTP/1.1 200 OK
  1. 单独对文件进行限制:
    在配置文件中增加:

        
        Order deny,allow
        Deny from all
        Allow from 127.0.0.1
 \
 \     

  1. 禁止解析php代码:
    增加下面代码:
  
                php_admin_flag engine off  #关闭php解析
                  #匹配文件类型
                Order allow,Deny
                Deny from all
                \
            \
  1. 针对浏览器标识user_agent:
    \
            RewriteEngine on
            RewriteCond %{HTTP_USER_AGENT} .*curl.* [NC,OR]   #
            RewriteCond %{HTTP_USER_AGENT} .*baidu.com.* [NC]
            RewriteRule .* - [F]
        \

%{HTTP_USER_AGENT}为user_agent的内置变量,当user_agent匹配curl或者baidu.com时,都会触发规则
OR:表示或者,NC表示不区分大小写
F:相当于Forbidden

测试:
[root@ligenkelong ~]# curl -x127.0.0.1:80 111.com -I
HTTP/1.1 403 Forbidden
[root@ligenkelong ~]# curl -x127.0.0.1:80 111.com -I -A “111”
HTTP/1.1 200 OK

三.php配置:

php的配置文件,查看配置文件位置:

[root@ligenkelong ~]# /usr/local/php/bin/php -i |grep -i "loaded configuration file"
Loaded Configuration File => (none)

或者创建当前站点目录下创建一个 phpinfo()的php文件,浏览器访问

Configuration File (php.ini) Path  /usr/local/php/etc 

配置:

[root@ligenkelong php-5.6.39]# cd /usr/local/src/php-5.6.39/
 [root@ligenkelong php-5.6.39]# cp php.ini-development  /usr/local/php/etc/php.ini
[root@ligenkelong php-5.6.39]# /usr/local/apache2.4/bin/apachectl -t
[root@ligenkelong php-5.6.39]# /usr/local/apache2.4/bin/apachectl graceful

定义时区(配置文件):

date.timezone = Asia/ShangHai

关闭错误信息输出到浏览器上:

display_errors = Off

配置错误日志:
error_log = /tmp/php_errors.log
error_reporting = E_ALL #把所有的错误都记录下来

禁止函数:
disable_functions = eval,assert,popen,passthru,escapeshellarg,escapeshellcmd,passthru,exec,system,chroot,scandir,chgrp,chown,escapeshellcmd,escapeshellarg,shell_exec,proc_get_status,ini_alter,ini_restore,dl,pfsockopen,openlog,syslog,readlink,symlink,leak,popepassthru,stream_socket_server,popen,proc_open,proc_close,phpinfo

将网站限定目录open_basedir:
限制所有站点的目录:

[root@ligenkelong 111.com]# vim /usr/local/php/etc/php.ini
open_basedir = /data/wwwroot/111.com:/tmp

单个单个虚拟主机限制,修改虚拟主机配置:

[root@ligenkelong 111.com]# vim /usr/local/apache2.4/conf/extra/httpd-vhosts.conf
php_admin_value open_basedir "/data/wwwroot/111.com:/tmp/"

四.php扩展安装:

举例redis:

[root@ligenkelong phpredis-develop]# cd /usr/local/src/
[root@ligenkelong phpredis-develop]# wget https://codeload.github.com/phpredis/phpredis/zip/develop  #它是一个zip包
[root@ligenkelong phpredis-develop]# mv develop phpredis-develop.zip
[root@ligenkelong phpredis-develop]# unzip phpredis-develop.zip
[root@ligenkelong phpredis-develop]# cd phpredis-develop
[root@ligenkelong phpredis-develop]# /usr/local/php/bin/phpize   #生成configure配置文件
如果失败,安装:
[root@ligenkelong phpredis-develop]# yum install -y autoconf
[root@ligenkelong phpredis-develop]# ./configure --with-php-config=/usr/local/php/bin/php-config 
[root@ligenkelong phpredis-develop]# make 
扩展模块位置查询:
[root@ligenkelong phpredis-develop]# /usr/local/php/bin/php -i |grep -i extension_dir
[root@ligenkelong phpredis-develop]# ls /usr/local/php/lib/php/extensions/no-debug-zts-20131226
opcache.so  pdo_mysql.so

在配置文件中写入:

[root@ligenkelong phpredis-develop]# vim /usr/local/php/etc/php.ini
 extension=redis.so
[root@ligenkelong phpredis-develop]# /usr/local/php/bin/php -m |grep redis
