一、系统安装
二、编译安装基本环境
三、配置虚拟主机及基本性能调优
四、基本安全设置
五、附录及相关介绍
一、系统安装
1. 分区
/boot 100M左右
SWAP 物理内存的2倍(如果你的物理内存大于4G以上，分配4G即可)
/ 15G
/usr/local 20G (用于安装软件)
/data 剩余所有空间
2. 系统初始化脚本(根据具体需求关闭不需要的服务)
#vi init.sh
-------------------cut begin-------------------------------------------
#welcome
cat << EOF
+--------------------------------------------------------------+
| === Welcome to Centos System init === |
+--------------
+----------------------Author:NetSeek--------------------------+
EOF
#disable ipv6
cat << EOF
+--------------------------------------------------------------+
| === Welcome to Disable IPV6 === |
+--------------------------------------------------------------+
EOF
echo "alias net-pf-10 off" >> /etc/modprobe.conf
echo "alias ipv6 off" >> /etc/modprobe.conf
/sbin/chkconfig --level 35 ip6tables off
echo "ipv6 is disabled!"
#disable selinux
sed -i '/SELINUX/s/enforcing/disabled/' /etc/selinux/config
echo "selinux is disabled,you must reboot!"
#vim
sed -i "8 s/^/alias vi='vim'/" /root/.bashrc
echo 'syntax on' > /root/.vimrc
#zh_cn
sed -i -e 's/^LANG=.*/LANG="zh_CN.GB18030"/' /etc/sysconfig/i18n
#tunoff services
#--------------------------------------------------------------------------------
cat << EOF
+--------------------------------------------------------------+
| === Welcome to Tunoff services === |
+--------------------------------------------------------------+
EOF
#---------------------------------------------------------------------------------
for i in `ls /etc/rc3.d/S*`
do
CURSRV=`echo $i|cut -c 15-`
echo $CURSRV
case $CURSRV in
crond | irqbalance | microcode_ctl | network | random | sendmail | sshd | syslog | local | mysqld )
echo "Base services, Skip!"
;;
*)
echo "change $CURSRV to off"
chkconfig --level 235 $CURSRV off
service $CURSRV stop
;;
esac
done
-------------------cut end-------------------------------------------
#sh init.sh (执行上面保存的脚本，仍后重启)
二、编译安装基本环境
1. 安装准备
1) 系统约定
软件源代码包存放位置 /usr/local/src
源码包编译安装位置(prefix) /usr/local/software_name
脚本以及维护程序存放位置 /usr/local/sbin
MySQL 数据库位置 /data/mysql/data（可按情况设置）
Apache 网站根目录 /data/www/wwwroot（可按情况设置）
Apache 虚拟主机日志根目录 /data/www/logs（可按情况设置）
Apache 运行账户 www:www (useradd -d /data/www/;chown /data/www/wwwroot)
2) 系统环境部署及调整
检查系统是否正常
# tail -n100 /var/log/messages （检查有无系统级错误信息）
# dmesg （检查硬件设备是否有错误信息）
# ifconfig（检查网卡设置是否正确）
# ping （检查网络是否正常）
3) 使用 yum 程序安装所需开发包（以下为标准的 RPM 包名称）
#rpm --import
#yum install ntp vim-enhanced gcc gcc-c++ gcc-g77 flex bison autoconf automake bzip2-devel \
ncurses-devel zlib-devel libjpeg-devel libpng-devel libtiff-devel freetype-devel libXpm-devel \
gettext-devel pam-devel kernel
4) 定时校正服务器时钟，定时与中国国家授时中心授时服务器同步
# crontab -e
加入一行：
15 3 * * * /usr/sbin/ntpdate 210.72.145.44 > /dev/null 2>&1
2. 编译安装软件包
源码编译安装所需包(Source)
1) GD2
# cd /usr/local/src
# tar xvf gd-2.0.35.tar.gz
# cd gd-2.0.35
# ./configure --prefix=/usr/local/gd2
# make
# make install
2) LibXML2
# cd /usr/local/src
# tar xvf libxml2-2.6.29.tar.bz2
# cd libxml2-2.6.29
# ./configure --prefix=/usr/local/libxml2
# make
# make install
3) LibMcrypt
# cd /usr/local/src
# tar xvf libmcrypt-2.5.8.tar.bz2
# cd libmcrypt-2.5.8
# ./configure --prefix=/usr/local/libmcrypt
# make
# make install
4) Apache日志截断程序
# cd /usr/local/src
# tar xvf cronolog-1.6.2.tar.gz
# cd cronolog-1.6.2
# ./configure --prefix=/usr/local/cronolog
# make
# make install
3. 升级OpenSSL和OpenSSH
# cd /usr/local/src
# tar xvf openssl-0.9.8g.tar.gz
# cd openssl-0.9.8g
# ./config --prefix=/usr/local/openssl
# make
# make test
# make install
# cd ..
# tar xvf openssh-5.0p1.tar.gz
# cd openssh-5.0p1
# ./configure \
"--prefix=/usr" \
"--with-pam" \
"--with-zlib" \
"--sysconfdir=/etc/ssh" \
"--with-ssl-dir=/usr/local/openssl" \
"--with-md5-passwords"
# make
# make install
1) 禁用 SSH V1 协议
找到#Protocol 2,1改为：Protocol 2
2) 禁用服务器端GSSAPI
找到以下两行，并将它们注释：
GSSAPIAuthentication yes
GSSAPICleanupCredentials yes
3) 禁用 DNS 名称解析
找到：#UseDNS yeas改为：UseDNS no
4)禁用客户端 GSSAPI
# vi /etc/ssh/ssh_config 找到：GSSAPIAuthentication yes 将这行注释掉。
最后，确认修改正确后重新启动 SSH 服务
# service sshd restart
# ssh -v
确认 OpenSSH 以及 OpenSSL 版本正确。
以上SSH配置可利用以下脚本自动修改:
-------------------cut begin-------------------------------------------
#init_ssh
ssh_cf="/etc/ssh/sshd_config"
sed -i -e '74 s/^/#/' -i -e '76 s/^/#/' $ssh_cf
sed -i "s/#UseDNS yes/UseDNS no/" $ssh_cf
#client
sed -i -e '44 s/^/#/' -i -e '48 s/^/#/' $ssh_cf
echo "ssh is init is ok.............."
-------------------cut end---------------------------------------------
三、编译安装A.M.P环境
1.下载软件编译安装
1)下载软件
# cd /usr/local/src
httpd-2.2.8.tar.gz
mysql-5.0.51b.tar.gz
php-5.2.6.tar.bz2
ZendOptimizer-3.3.3-linux-glibc23-i386.tar.gz
2) 安装MySQL
查看分析你的CPU型号:
查找您的GCC编译参数.
确定系统CPU类型：
# cat /proc/cpuinfo | grep "model name"
执行后会看到系统中CPU的具体型号，记下CPU型号。
# tar xvf mysql-5.0.51b.tar.gz
# cd mysql-5.0.51b
# vi mysql.sh
-------------------cut begin-------------------------------------------
CHOST="i686-pc-linux-gnu"

make
make install
mkdir /usr/local/php/etc
cp php.ini-dist /usr/local/php/etc/php.ini
5)Xcache的安装.
#tar xvf xcache-1.2.2.tar.gz
#/usr/local/php/bin/phpize
./configure --enable-xcache --enable-xcache-coverager --with-php-config=/usr/local/php/bin/php-config \
--enable-inline-optimization --disable-debug
#vi /usr/local/php/etc/php.ini (将以下内容加入php.ini最后面)
-------------------cut begin-------------------------------------------
[xcache-common]
zend_extension = /usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/xcache.so
[xcache.admin]
xcache.admin.user = "admin"
;如何生成md5密码: echo -n "password"| md5sum
xcache.admin.pass = "035d849226a8a10be1a5e0fec1f0f3ce" #密码为52netseek
[xcache]
; Change xcache.size to tune the size of the opcode cache
xcache.size = 24M
xcache.shm_scheme = "mmap"
xcache.count = 4
xcache.slots = 8K
xcache.ttl = 0
xcache.gc_interval = 0
; Change xcache.var_size to adjust the size of variable cache
xcache.var_size = 8M
xcache.var_count = 1
xcache.var_slots = 8K
xcache.var_ttl = 0
xcache.var_maxttl = 0
xcache.var_gc_interval = 300

xcache.coredump_directory = ""
xcache.cacher = On
xcache.stat = On
xcache.optimizer = Off
[xcache.coverager]
xcache.coverager = On
xcache.coveragedump_directory = ""
-------------------cut end---------------------------------------------
6) 安装Zend Optimizer
# cd /usr/local/src
# tar xzvf ZendOptimizer-3.3.3-linux-glibc23-i386.tar.gz
# ./ZendOptimizer-3.3.3-linux-glibc23-i386/install.sh
安装Zend Optimizer过程的最后不要选择重启Apache。
2. 整合Apache与PHP及系统初化配置.
1)整合Apache与PHP
# vi /usr/local/apache2/conf/httpd.conf
找到：
AddType application/x-gzip .gz .tgz
在该行下面添加
AddType application/x-httpd-php .php
找到：
DirectoryIndex index.html
将该行改为
DirectoryIndex index.html index.htm index.php
找到：
#Include conf/extra/httpd-mpm.conf
#Include conf/extra/httpd-info.conf
#Include conf/extra/httpd-vhosts.conf (虚拟主机配置文件存放目录.)
#Include conf/extra/httpd-default.conf
去掉前面的“#”号，取消注释。
注意：以上 4 个扩展配置文件中的设置请按照相关原则进行合理配置！
修改完成后保存退出。
# /usr/local/apache2/bin/apachectl restart
2)查看确认L.A.M.P环境信息、提升 PHP 安全性
在网站根目录放置 info.php 脚本，检查phpinfo中的各项信息是否正确。
phpinfo();
?>
确认 PHP 能够正常工作后，在 php.ini 中进行设置提升 PHP 安全性,禁掉危险的函数.
# vi /etc/php.ini找到：disable_functions =设置为：phpinfo,passthru,exec,system,chroot,scandir,chgrp,chown,shell_exec,proc_open,proc_get_status,ini_alter,ini_alter,ini_restore,dl,pfsockopen,openlog,syslog,readlink,symlink,popepassthru,stream_socket_server
3)脚本自动完成初始化配置(以上配置可以用脚本自动化完成)
#cat init_apache_php.sh
-------------------cut begin-------------------------------------------
#!/bin/bash
#Written by :NetSeek
#init_httpd.conf
http_cf="/usr/local/apache2/conf/httpd.conf"
sed -i -e "s/User daemon/User www/" -i -e "s/Group daemon/Group www/" $http_cf
sed -i -e '121 s/^/#/' -i -e '122 s/^/#/' $http_cf
sed -i 's#DirectoryIndex index.html# DirectoryIndex index.php index.html index.htm#/g' $http_cf
sed -i -e '374 s/^#//g' -i -e '389 s/^#//g' -i -e '392 s/^#//g' -i -e '401 s/^#//g' $http_cf
#init_php(PHP安全设置及隐藏PHP版本)
php_cf="/usr/local/php/etc/php.ini"
sed -i '205 s#;open_basedir =#open_basedir = /data/www/wwwroot:/tmp#g' $php_cf
sed -i '210 s#disable_functions =#disable_functions = phpinfo,passthru,exec,system,chroot,scandir,chgrp,chown,shell_exec,proc_open,proc_get_status,ini_alter,ini_alter,ini_restore,dl,pfsockopen,openlog,syslog,readlink,symlink,popepassthru,stream_socket_server#g' $php_cf
sed -i '/expose_php/s/On/Off/' $php_cf
sed -i '/display_errors/s/On/Off/' $php_cf
-------------------cut end----------------------------------------
三、配置虚拟主机及基本性能调优
1) 配置虚拟主机:
#vi /usr/local/apache2/conf/extra/httpd-vhosts.conf
NameVirtualHost *:80
ServerAdmin
DocumentRoot "/data/www/wwwroot/linuxtone.org"
ServerName
ServerAlias bbs.linxutone.org
ErrorLog "logs/dummy-host.example.com-error_log"
CustomLog "|/usr/sbin/cronolog /data/logs/access_%Y%m%d" combined
2).基本性能调优参考:(更多的调优相关文章请关注:性能调优相关的贴子)
#vi /usr/local/apache2/conf/extra/httpd-default.conf
----------------------------
Timeout 15
KeepAlive Off
MaxKeepAliveRequests 50
KeepAliveTimeout 5
UseCanonicalName Off
AccessFileName .htaccess
ServerTokens Prod
ServerSignature Off
HostnameLookups Off
---------------------------
#vi /usr/local/apache2/conf/extra/httpd-mpm.conf
ServerLimit 2000
StartServers 10
MinSpareServers 10
MaxSpareServers 15
MaxClients 2000
MaxRequestsPerChild 10000
3).Apache日志处理相关问题汇总贴()
利用awstats分析网站日志:
忽略不需要的日志配置参考具体请据据具体问题分析：
LogFormat "%{X-Forwarded-For}i %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined
#下面加入如下内容:
---------------------------------------------
# filter the localhost visit
SetEnvIf Remote_Addr "127\.0\.0\.1" dontlog
# filter some special directories
SetEnvIf Request_URI "^ZendPlatform.*[code]
# filter the localhost visit
SetEnvIf Remote_Addr "127\.0\.0\.1" dontlog
# filter some special directories
SetEnvIf Request_URI "^ZendPlatform.*[ DISCUZ_CODE_9 ]quot; dontlog
SetEnvIf Request_URI \.healthcheck\.html$ dontlog
SetEnvIf Remote_Addr "::1" dontlog
SetEnvIf Request_URI "\.getPing.php[ DISCUZ_CODE_9 ]quot; dontlog
SetEnvIf Request_URI "^/error\.html[ DISCUZ_CODE_9 ]quot; dontlog
SetEnvIf Request_URI "\.gif[ DISCUZ_CODE_9 ]quot; dontlog
SetEnvIf Request_URI "\.jpg[ DISCUZ_CODE_9 ]quot; dontlog
SetEnvIf Request_URI "\.css[ DISCUZ_CODE_9 ]quot; dontlog
RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://(www\.)?mydomain.com/.*$ [NC]
RewriteRule \.(gif|jpg)$ http://网站域名/nolink.png [R,L]
----------------------------------------
四、基本安全设置
1)iptables 封锁相关端口(推荐读CU白金大哥的两小时玩转iptables)
2)SSH全安(修改SSH端口限制来源IP登陆，或者参考)
3)Linux防Arp攻击策略()
4)注意(还是那句老话:安全工作从细节做起!)
