Nginx在LAMP上的擴充
在原來搭建好LAMP的基礎上安裝nginx
[root@localhost nginx-1.0.15]# yum install libxslt-devel
[root@localhost ~]# tar xf pcre-8.33.tar.gz -C /usr/src/
[root@localhost ~]# cd /usr/src/pcre-8.33/
[root@localhost pcre-8.33]# ./configure && make && make install
[root@localhost nginx-1.0.15]# wget http://nginx.org/download/nginx-1.0.15.tar.gz

PHP安裝
[root@localhost ~]# tar xf /softs/php-5.3.27.tar.bz2 -C /usr/src/
[root@localhost php-5.3.27]# ./configure --disable-ipv6 --with-libxml-dir=/usr --with-openssl=/usr --with-pcre-regex=/usr/local --with-zlib=/usr --with-bz2=/usr --enable-calendar --with-curl=/usr --with-pcre-dir=/usr/local --enable-ftp --with-openssl-dir=/usr --with-gd=/usr/local --with-jpeg-dir=/usr/local --with-png-dir=/usr/local --with-zlib-dir=/usr/local --with-xpm-dir=/usr --with-freetype-dir=/usr/local --enable-gd-native-ttf --enable-gd-jis-conv --with-mhash=/usr/local --enable-mbstring --with-mcrypt=/usr/local --with-mysql=/usr/local/mysql --with-mysql-sock=/var/run/mysqld/mysql5.socket --with-mysqli=/usr/local/mysql/bin/mysql_config --with-snmp=/usr --enable-sockets --enable-zip && make && make install

[root@localhost cgi]# pwd
/usr/src/php-5.3.27/sapi/cgi
訪問 127.0.0.1/index.php
現在只有一個php-cgi進程，當大量的並發請求時，這是不夠的。所以我用壓力測試軟件http_load測試一下
[root@localhost softs]# wget http://icn.me/http_load_tar_gz
[root@localhost http_load-12mar2006]# make && make install
[root@localhost www]# http_load -parallel 100 -seconds 10 url.txt

當並發數為100時，掛掉了，所以我們需要差生多個php-cgi進程，這裡引入一個工具spqwn-fcgi
[root@localhost spawn-fcgi-1.6.3]# wget http://download.lighttpd.net/spawn-fcgi/releases-1.6.x/spawn-fcgi-1.6.3.tar.gz
[root@localhost spawn-fcgi-1.6.3]# tar xf spawn-fcgi-1.6.3.tar.gz
