Nginx 0.7.14 + PHP 5.2.6的搭建(上)

安装步骤:
  (系统要求:Linux 2.6+ 内核,本文中的Linux操作系统为CentOS 5.1,另在RedHat AS4上也安装成功)

   一、获取相关开源程序:
  1、利用CentOS Linux系统自带的yum命令安装、升级所需的程序库(RedHat等其他Linux发行版可从安装光盘中找到这些程序库的RPM包,进行安装):
sudo -s
LANG=C
yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel


  2、RedHat等其他Linux发行版 可从安装光盘中找到这些程序库的RPM包(事先可通过类似“rpm -qa | grep libjpeg”的命令查看所需的RPM包是否存在,通常是“xxx-devel”不存在,需要安装)。RedHat可以直接利用CentOS的RPM包安装,以下是RPM包下载网址:
  ①RedHat AS4 & CentOS 4
   [url]http://mirror.be10.com/centos/4/os/i386/CentOS/RPMS/[/url]
   [url]http://mirror.be10.com/centos/4/os/x86_64/CentOS/RPMS/[/url]

  ②RedHat AS5 & CentOS 5
   [url]http://mirror.be10.com/centos/5/os/i386/CentOS/[/url]
   [url]http://mirror.be10.com/centos/5/os/x86_64/CentOS/[/url]

  ③RPM包搜索网站
   [url]http://rpm.pbone.net/[/url]
   [url]http://www.rpmfind.net/[/url]

  3、下载程序源码包:
  本文中提到的所有开源软件为截止到2008年8月28日的最新稳定版。
mkdir -p /data0/software
cd /data0/software
wget [url]http://sysoev.ru/nginx/nginx-0.7.14.tar.gz[/url]
wget [url]http://www.php.net/get/php-5.2.6.tar.gz/from/this/mirror[/url]
wget [url]http://php-fpm.anight.org/downloads/head/php-5.2.6-fpm-0.5.8.diff.gz[/url]
wget [url]http://blog.s135.com/soft/linux/mysql/mysql-5.1.26-rc.tar.gz[/url]
wget [url]http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.12.tar.gz[/url]
wget [url]http://mirror.optus.net/sourceforge/m/mc/mcrypt/libmcrypt-2.5.8.tar.gz[/url]
wget [url]http://mirror.optus.net/sourceforge/m/mc/mcrypt/mcrypt-2.6.7.tar.gz[/url]
wget [url]http://pecl.php.net/get/memcache-2.2.3.tgz[/url]
wget [url]http://mirror.optus.net/sourceforge/m/mh/mhash/mhash-0.9.9.tar.gz[/url]
wget [url]ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-7.7.tar.gz[/url]
wget [url]http://bart.eaccelerator.net/source/0.9.5.3/eaccelerator-0.9.5.3.tar.bz2[/url]


   二、安装PHP 5.2.6(FastCGI模式)
  1、编译安装PHP 5.2.6所需的支持库:
tar zxvf libiconv-1.12.tar.gz
cd libiconv-1.12/
./configure --prefix=/usr/local
make
make install
cd ../

tar zxvf libmcrypt-2.5.8.tar.gz
cd libmcrypt-2.5.8/
./configure
make
make install
/sbin/ldconfig
cd libltdl/
./configure --enable-ltdl-install
make
make install
cd ../../

tar zxvf mhash-0.9.9.tar.gz
cd mhash-0.9.9/
./configure
make
make install
cd ../

cp /usr/local/lib/libmcrypt.* /usr/lib
ln -s /usr/local/lib/libmhash.so.2 /usr/lib/libmhash.so.2

tar zxvf mcrypt-2.6.7.tar.gz
cd mcrypt-2.6.7/
./configure
make
make install
cd ../


  2、编译安装MySQL 5.1.26-rc
/usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql mysql
tar zxvf mysql-5.1.26-rc.tar.gz
cd mysql-5.1.26-rc/
./configure --prefix=/usr/local/webserver/mysql/ --enable-assembler --with-extra-charsets=complex --enable-thread-safe-client --with-big-tables --with-readline --with-ssl --with-embedded-server --enable-local-infile
make && make install
chmod +w /usr/local/webserver/mysql
chown -R mysql:mysql /usr/local/webserver/mysql
cp support-files/my-medium.cnf /usr/local/webserver/mysql/my.cnf
cd ../


  附:以下为附加步骤,如果你想在这台服务器上运行MySQL数据库,则执行以下两步。如果你只是希望让PHP支持MySQL扩展库,能够连接其他服务器上的MySQL数据库,那么,以下两步无需执行。
  ①、以mysql用户帐号的身份建立数据表:
/usr/local/webserver/mysql/bin/mysql_install_db --defaults-file=/usr/local/webserver/mysql/my.cnf --basedir=/usr/local/webserver/mysql --datadir=/usr/local/webserver/mysql/data --user=mysql --pid-file=/usr/local/webserver/mysql/mysql.pid --skip-locking --port=3306 --socket=/tmp/mysql.sock


  ②、启动MySQL(最后的&表示在后台运行)
/bin/sh /usr/local/webserver/mysql/bin/mysqld_safe --defaults-file=/usr/local/webserver/mysql/my.cnf &


  3、编译安装PHP(FastCGI模式)
tar zxvf php-5.2.6.tar.gz
gzip -cd php-5.2.6-fpm-0.5.8.diff.gz | patch -d php-5.2.6 -p1
cd php-5.2.6/
./configure --prefix=/usr/local/webserver/php --with-config-file-path=/usr/local/webserver/php/etc --with-mysql=/usr/local/webserver/mysql --with-mysqli=/usr/local/webserver/mysql/bin/mysql_config --with-iconv-dir=/usr/local --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-discard-path --enable-safe-mode --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --with-curlwrappers --enable-mbregex --enable-fastcgi --enable-fpm --enable-force-cgi-redirect --enable-mbstring --with-mcrypt --with-gd --enable-gd-native-ttf --with-openssl
sed -i 's#-lz -lm -lxml2 -lz -lm -lxml2 -lz -lm -lcrypt#& -liconv#' Makefile
make
make install
cp php.ini-dist /usr/local/webserver/php/etc/php.ini
cd ../

4、编译安装PHP5扩展模块
tar zxvf memcache-2.2.3.tgz
cd memcache-2.2.3/
/usr/local/webserver/php/bin/phpize
./configure --with-php-config=/usr/local/webserver/php/bin/php-config
make
make install
cd ../

tar jxvf eaccelerator-0.9.5.3.tar.bz2
cd eaccelerator-0.9.5.3/
/usr/local/webserver/php/bin/phpize
./configure --enable-eaccelerator=shared --with-php-config=/usr/local/webserver/php/bin/php-config
make
make install
cd ../

  5、修改php.ini文件
   手工修改:查找/usr/local/webserver/php/etc/php.ini中的extension_dir = "./"
  修改为extension_dir = "/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/"
  并在此行后增加以下几行,然后保存:
  extension = "memcache.so"

  再查找output_buffering = Off
  修改为output_buffering = On

   自动修改:若嫌手工修改麻烦,可执行以下shell命令,自动完成对php.ini文件的修改:
sed -i 's#extension_dir = "./"#extension_dir = "/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/"\nextension = "memcache.so"\n#' /usr/local/webserver/php/etc/php.ini
sed -i 's#output_buffering = Off#output_buffering = On#' /usr/local/webserver/php/etc/php.ini

  6、配置eAccelerator加速PHP:
mkdir -p /usr/local/webserver/eaccelerator_cache
vi /usr/local/webserver/php/etc/php.ini

  按shift+g键跳到配置文件的最末尾,加上以下配置信息:
引用
[eaccelerator]
zend_extension="/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so"
eaccelerator.shm_size="128"
eaccelerator.cache_dir="/usr/local/webserver/eaccelerator_cache"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="300"
eaccelerator.shm_prune_period="120"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"

  修改配置文件:
vi /etc/sysctl.conf

  输入以下内容:
kernel.shmmax = 134217728

  然后执行以下命令使配置生效:
/sbin/sysctl -p


  7、创建www用户和组,以及供blog.s135.com和 [url]www.s135.com[/url]两个虚拟主机使用的目录:
/usr/sbin/groupadd www -g 48
/usr/sbin/useradd -u 48 -g www www
mkdir -p /data0/htdocs/blog
chmod +w /data0/htdocs/blog
chown -R www:www /data0/htdocs/blog
mkdir -p /data0/htdocs/www
chmod +w /data0/htdocs/www
chown -R www:www /data0/htdocs/www
