Nginx在LAMP上的扩充

在原来搭建好LAMP的基础上安装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

[root@localhost nginx-1.0.15]# ./configure --error-log-path=/var/log/nginx/error.log --pid-path=/var/run/nginx/nginx.pid --user=daemon --group=daemon --with-rtsig_module --with-select_module --with-poll_module --with-ipv6 --with-http_ssl_module --with-http_realip_module  --with-http_addition_module --with-http_xslt_module --with-http_image_filter_module --with-http_sub_module --with-http_dav_module --with-http_gzip_static_module --with-http_flv_module --with-http_perl_module --with-perl=/usr/bin/perl --http-log-path=/var/log/nginx/access.log --with-pcre --with-pcre=/usr/src/pcre-8.33/  --with-http_stub_status_module

[root@localhost nginx-1.0.15]# make && make install

PHP安装

[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]# ./php-cgi -a -b 127.0.0.1:9000 -c /usr/local/lib/php.ini &
[2] 9879
[1]   宸叉姝?              ./php-cgi -a -b 127.0.0.1:9000 -c /usr/local/lib/php.ini

[root@localhost cgi]# pwd
/usr/src/php-5.3.27/sapi/cgi

访问 127.0.0.1/index.php

现在只有一个php-cgi进程，当大量的并发请求时，这是不够的。所以我用压力测试软件http_load测试一下

[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

当并发数为100时，挂掉了，所以我们需要差生多个php-cgi进程，这里引入一个工具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 
[root@localhost spawn-fcgi-1.6.3]# cd spawn-fcgi-1.6.3
[root@localhost spawn-fcgi-1.6.3]# ./configure && make && make install

[root@localhost src]# spawn-fcgi -f /usr/local/bin/php
spawn-fcgi: no socket given (use either -p or -s)
[root@localhost src]# spawn-fcgi -f /usr/local/bin/php-cgi -a 127.0.0.1 -u daemon -p 9000 -C 150
spawn-fcgi: child spawned successfully: PID: 11498
[root@localhost src]# ps -e | grep php | wc
    151     604    4832

[root@localhost www]# http_load -parallel 100 -seconds 10 url.txt

HTTP response codes:

现在php就没有死了。
