Apache

安装http前先安装aprapu

#cd srclib/apr

#./configure

#make&&make install

#cd ../apr-util/

#./configure --with-apr=/usr/local/apr/bin/apr-1-config

#make&&make install

#cd ../..

安装http

#./configure --prefix=/usr/local/apache --enable-rewrite --enable-so  --with-apr=/usr/local/apr/bin/apr-1-config --with-apr-util=/usr/local/apr/bin/apu-1-config

#make&&make install

 

修改/usr/local/apache/conf/httpd.conf

 

PidFile /var/run/httpd.pid

 

#DocumentRoot "/usr/local/apache/htdocs"

 

NameVirtualHost serverip:80

 

# The following directives modify normal HTTP response behavior to

# handle known problems with browser implementations.

#

BrowserMatch "Mozilla/2" nokeepalive

BrowserMatch "MSIE 4\.0b2;" nokeepalive downgrade-1.0 force-response-1.0

BrowserMatch "RealPlayer 4\.0" force-response-1.0

BrowserMatch "Java/1\.0" force-response-1.0

BrowserMatch "JDK/1\.0" force-response-1.0

 

#

# The following directive disables redirects on non-GET requests for

# a directory that does not include the trailing slash.  This fixes a

# problem with Microsoft WebFolders which does not appropriately handle

# redirects for folders with DAV methods.

# Same deal with Apple's DAV filesystem and Gnome VFS support for DAV.

#

BrowserMatch "Microsoft Data Access Internet Publishing Provider" redirect-carefully

BrowserMatch "MS FrontPage" redirect-carefully

BrowserMatch "^WebDrive" redirect-carefully

BrowserMatch "^WebDAVFS/1.[0123]" redirect-carefully

BrowserMatch "^gnome-vfs/1.0" redirect-carefully

BrowserMatch "^XML Spy" redirect-carefully

BrowserMatch "^Dreamweaver-WebDAV-SCM1" redirect-carefully

 

#mod_deflate Browser set

BrowserMatch ^Mozilla/4 gzip-only-text/html

BrowserMatch ^Mozilla/4\.0[678] no-gzip

#./config.nice

#make&&make install

修改/etc/httpd/conf/httpd.conf

AddType application/x-httpd-php .php 

AddType application/x-httpd-php-source .phps

DirectoryIndex index.html index.html.var index.php

修改/usr/local/php5/lib/php.ini

ftp

wget

tar -zxvf pure-ftpd.tar.gz

./configure --prefix=/usr/local/pure-ftpd

make install

mkdir /usr/local/pure-ftpd/etc

cp configuration-file/pure-config.pl /usr/local/pure-ftpd/sbin/

cp configuration-file/pure-ftpd.conf /usr/local/pure-ftpd/etc/

chmod a+x /usr/local/pure-ftpd/sbin/pure-config.pl

cp pam/pure-ftpd /etc/pam.d/

cd contrib

编辑 redhat.init 文件。修改

fullpath=/usr/local/sbin/$prog   -->  fullpath=/usr/local/pure-ftpd/sbin/$prog

pureftpwho=/usr/local/sbin/pure-ftpwho   -->   pureftpwho=/usr/local/pure-ftpd/sbin/pure-ftpwho

$fullpath /etc/pure-ftpd.conf --daemonize   -->   $fullpath /usr/local/pure-ftpd/etc/pure-ftpd.conf --daemonize

cp redhat.init  /etc/rc.d/init.d/pureftpd

service pureftpd start

 

 

监控:

安装nrpe  用于线下245nagios监控

安装snmp用于线下245cacti监控

 

安全

 

更换ssh,ftp端口(暂不执行)
 

ssh:

service iptables stop

切记先关掉防火墙,以免出现悲剧

sed -ir 's/#Port\s+22/Port\ 22008/' /etc/ssh/sshd_config

service sshd restart

 

ftp

修改/usr/local/etc/pure-ftpd.conf

找到#bind 127.0.0.1,21

修改为bind     21201

service pureftpd restart

 

 

 

从服务器随时下载同步主服务器的php程序(参见OJO的同步脚本)

 

Mod_evasive

用途,特点:

mod_evasive Apachehttpd)服务器的防DDOS的一个模块。对于WEB服务器来说,是目前比较好的一个防护DDOS攻击的扩展模块。虽然并不能完全防御DDOS攻击,但在一定条件下,还是起到缓服Apachehttpd)服务器的压力。

 

安装:

是官方网站,可以下载最新版本

 

 

#tar zxvf mod_evasive_1.10.1.tar.gz

#cd mod_evasive

#/usr/local/apache/bin/apxs -cia mod_evasive20.c

 

 

 

httpd.conf中下面加入:

 

DOSHashTableSize 3097

DOSPageCount 2

DOSSiteCount 50

DOSPageInterval 1

DOSSiteInterval 1

DOSBlockingPeriod 10

Include modevasive.d/*

 

 

 

 

 

/usr/local/apache下创建文件夹modevasive.d

创建白名单文件whitelist.conf

内容例如:

DOSWhitelist 127.0.0.1

 

不会挡住来自本机的可能ddos攻击

 

 

重启apache服务

/usr/local/apache/bin/apachectl restart

 

 

测试:

mod_evasive中自带一个test.pl的脚本。用于测试是否配置成功

test.pl脚本内将127.0.0.1改为要测试的服务器ip地址,然后执行测试脚本:

perl test.pl

或者用apache自带的ab工具:

/usr/local/apache/bin/ab -n 1000 -c 50

如果成功挡住ddos攻击会在/tmp下面生成例如名字为dos-127.0.0.1的文件。证明成功

 

iptables

开放3306端口可以被远程访问,但是限制只有从服务器ip地址有此权限

 

优化:

安装eaccelerator

具体安装方法查看包内readme

 

安装zend Optimizer (仅支持5.2.x以下的php)

具体安装方法查看包内readme

 

Apache

httpd.conf

 

KeepAlive On

KeepAliveTimeout 15

MaxKeepAliveRequests 100

StartServers       8

MinSpareServers    5

MaxSpareServers   20

ServerLimit      1024

MaxClients       1024

MaxRequestsPerChild  4000

以上两个参数限定同一时间内允许接受的请求数量。如果需要增加需要两个参数都增加

 

隐藏apachephp版本:

Apache:

ServerTokens ProductOnly 

ServerSignature Off

Php.ini:

expose_php = Off

 

开启gzip压缩:

 

LoadModule headers_module modules/mod_headers.so

LoadModule deflate_module modules/mod_deflate.so

 

DeflateCompressionLevel 3

AddOutputFilter DEFLATE html xml php js css

SetOutputFilter DEFLATE

#BrowserMatch ^Mozilla/4 gzip-only-text/html

#BrowserMatch ^Mozilla/4\.0[678] no-gzip

#BrowserMatch \bMSIE !no-gzip !gzip-only-text/html

SetEnvIfNoCase Request_URI no-gzip dont-vary

SetEnvIfNoCase Request_URI .(?:exe|t?gz|zip|bz2|sit|rar)$ no-gzip dont-vary

SetEnvIfNoCase Request_URI .(?:pdf|mov|avi|mp3|mp4|rm)$ no-gzip dont-vary

 

开启mysql慢查询日志:

添加/etc/my.cnf

long_query_time = 2

log-slow-queries =  /home/data/slowquery.log

日志3天过期

expire_logs_days = 3
