纲要:
一、零碎装配
二、编译装配根底情况
三、设置装备部署编造主机及根底功能调优
四、根底安好设置
五、附录及相关引见

一、零碎装配
1. 分区
/boot 100M摆布
SWAP 物理内存的2倍(要是你的物理内存年夜于4G以上，分派4G即可)
/usr/local 15G (用于装配软件)
/data 残剩一切空间

2. 零碎初始化脚本(凭据注意需求关闭不必要的就事)
CODE:
#vi init.sh
-------------------cut begin-------------------------------------------
#welcome
cat << EOF
--------------------------------------------------------------
| === Welcome to Centos System init === |
--------------http://www.linuxtone.org------------------------
----------------------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 (实行上面生计的脚本，仍后重启)

二、编译装配根底情况

1. 装配准备
1) 零碎约定
软件源代码包存放地位 /usr/local/src
源码包编译装配地位(prefix) /usr/local/software_name
脚本以及维护步伐存放地位 /usr/local/sbin
MySQL 数据库地位 /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 编造主机日记根目录 /data/www/logs（可按情况设置）
Apache 运转账户 www:www

2) 零碎情况部署及调解
检查零碎能否正常
# tail -n100 /var/log/messages （检查有无零碎级错误信息）
# dmesg （检查硬件装备能否有错误信息）
# ifconfig（检查网卡设置能否正确）
# ping www.linuxtone.org （检查网络能否正常）

3) 运用 yum 步伐装配所需开拓包（以下为范例的 RPM 包称号）
#rpm --import http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
#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) 定时校正就事器时钟，定时与中国国度授时两头授时就事器同步
# crontab -e
插手一行：
15 3 * * * /usr/sbin/ntpdate 210.72.145.44 > /dev/null 2>&1

2. 编译装配软件包
源码编译装配所需包(Source)
1) GD2
# cd /usr/local/src
# tar xzvf 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 xjvf 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 xjvf libmcrypt-2.5.8.tar.bz2
# cd libmcrypt-2.5.8
# ./configure --prefix=/usr/local/libmcrypt
# make
# make install

4) Apache日记截断步伐
# cd /usr/local/src
# tar xzvf 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 xzvf openssl-0.9.8g.tar.gz
# cd openssl-0.9.8g
# ./config --prefix=/usr/local/openssl
# make
# make test
# make install
# cd ..
# tar xzvf 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 和谈
找到#Protocol 2,1改为：Protocol 2

2) 禁用就事器端GSSAPI
找到以下两行，并将它们标明：
GSSAPIAuthentication yes
GSSAPICleanupCredentials yes

3) 禁用 DNS 称号阐发
找到：#UseDNS yeas改为：UseDNS no

4)禁用客户端 GSSAPI
# vi /etc/ssh/ssh_config 找到：GSSAPIAuthentication yes 将这行标明掉。
最初，确认修更正确后重新启动 SSH 就事
# service sshd restart
# ssh -v
确认 OpenSSH 以及 OpenSSL 版本正确。

以上SSH设置装备部署可运用以下脚本自动修正:
CODE:
-------------------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、编译装配A.M.P情况

1.下载软件编译装配
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) 装配MySQL
查察阐发你的CPU型号:
http://gentoo-wiki.com/Safe_Cflags 查找您的GCC编译参数.
确定零碎CPU范例：
# cat /proc/cpuinfo | grep "model name"
实行后会看到零碎中CPU的注意型号，记下CPU型号。

# tar zxvf mysql-5.0.51b.tar.gz
# cd mysql-5.0.51b
# vi mysql.sh
CODE:
-------------------cut begin-------------------------------------------
CHOST="i686-pc-linux-gnu"
CFLAGS="-march=prescott -O2 -pipe -fomit-frame-pointer"
CXXFLAGS="${CFLAGS}"
./configure \
"--prefix=/usr/local/mysql" \
"--localstatedir=/data/mysql/data" \
"--with-comment=Source" \
"--with-server-suffix=-LinuxTone" \
"--with-mysqld-user=mysql" \
"--without-debug" \
"--with-big-tables" \
"--with-charset=gbk" \
"--with-collation=gbk_chinese_ci" \
"--with-extra-charsets=all" \
"--with-pthread" \
"--enable-static" \
"--enable-thread-safe-client" \
"--with-client-ldflags=-all-static" \
"--with-mysqld-ldflags=-all-static" \
"--enable-assembler" \
"--without-isam" \
"--without-innodb" \
"--without-ndb-debug"
make && make install
mkdir -p /data/mysql/data
useradd mysql -d /data/mysql -s /sbin/nologin
/usr/local/mysql/bin/mysql_install_db --user=mysql
cd /usr/local/mysql
chown -R root:mysql .
chown -R mysql /data/mysql/data
cp share/mysql/my-huge.cnf /etc/my.cnf
cp share/mysql/mysql.server /etc/rc.d/init.d/mysqld
chmod 755 /etc/rc.d/init.d/mysqld
chkconfig --add mysqld
/etc/rc.d/init.d/mysqld start

cd /usr/local/mysql/bin
for i in *; do ln -s /usr/local/mysql/bin/$i /usr/bin/$i; done

-------------------cut end---------------------------------------------

#sh mysql.sh 即可下手下手编译.

3) 编译装配Apache
# cd /usr/local/src
# tar zxvf httpd-2.2.8.tar.gz
# cd httpd-2.2.8
CODE:
# ./configure \
"--prefix=/usr/local/apache2" \
"--with-included-apr" \
"--enable-so" \
"--enable-deflate=shared" \
"--enable-expires=shared" \
"--enable-rewrite=shared" \
"--enable-static-support" \
"--disable-userdir"
# make
# make install
# echo '/usr/local/apache2/bin/apachectl start ' >> /etc/rc.local

4.)编译装配PHP

# tar xjvf php-5.2.6.tar.bz2
# cd php-5.2.6
CODE:
# ./configure \
"--prefix=/usr/local/php" \
"--with-apxs2=/usr/local/apache2/bin/apxs" \
"--with-config-file-path=/usr/local/php/etc" \
"--with-mysql=/usr/local/mysql" \
"--with-libxml-dir=/usr/local/libxml2" \
"--with-gd=/usr/local/gd2" \
"--with-jpeg-dir" \
"--with-png-dir" \
"--with-bz2" \
"--with-freetype-dir" \
"--with-iconv-dir" \
"--with-zlib-dir " \
"--with-openssl=/usr/local/openssl" \
"--with-mcrypt=/usr/local/libmcrypt" \
"--enable-soap" \
"--enable-gd-native-ttf" \
"--enable-memory-limit" \
"--enable-ftp" \
"--enable-mbstring" \
"--enable-exif" \
"--disable-ipv6" \
"--disable-cgi" \
"--disable-cli" #禁掉ipv6,禁掉cli形式，晋升速度和安好性.
# make
# make install
# mkdir /usr/local/php/etc
# cp php.ini-dist /usr/local/php/etc/php.ini

5)Xcache的装配.
#tar zxvf xcache-1.2.2.tar.gz
CODE:
#/usr/local/php-fcgi/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 (将以下内容插手php.ini最背面)
CODE:
-------------------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"
;怎样生成md5暗码: echo -n "password"| md5sum
xcache.admin.pass = "035d849226a8a10be1a5e0fec1f0f3ce" #暗码为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.test = Off
xcache.readonly_protection = On
xcache.mmap_path = "/tmp/xcache"
xcache.coredump_directory = ""
xcache.cacher = On
xcache.stat = On
xcache.optimizer = Off

[xcache.coverager]
xcache.coverager = On
xcache.coveragedump_directory = ""
-------------------cut end---------------------------------------------

6) 装配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
装配Zend Optimizer历程的最初不要选择重启Apache。


2. 整合Apache与PHP及零碎初化设置装备部署.
1)整合Apache与PHP
# vi /usr/local/apache2/conf/httpd.conf
找到：
AddType application/x-gzip .gz .tgz
在该行上面添加
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 (编造主机设置装备部署文件存放目录.)
#Include conf/extra/httpd-default.conf
去掉背面的“#”号，打消标明。
注意：以上 4 个扩展设置装备部署文件中的设置请凭据相关准绳进行公平设置装备部署！

修正完成后生计插手。
# /usr/local/apache2/bin/apachectl restart

2)查察确认L.A.M.P情况信息、晋升 PHP 安好性
在网站根目录布置 info.php 脚本，检查phpinfo中的各项信息能否正确。
