Nginx squid apache,php mysql Tutorial
Eaccelerator/memcache Preparatory work:
Referral server: Intel (R) Xeon (tm) CPU 3.00ghz * 2, 2GB mem, Scisc HDD
Operation system: centos4.4, kernel version 2.6.9-22.ELSMP,GCC version 3.4.4
Software：
Apache 2.2.3 (can use MPM mode)
PHP 5.2.0 (This version is selected because 5.2.0 's enginerelatively more efficient)
Eaccelerator 0.9.5 (accelerates PHP engine, also can encrypt PHP source program）
Memcache 1.2.0 (for Cache common Data）
Libevent 1.2a (required for memcache working mechanism)
MySQL 5.0.27 (choose binary version, save compilation work)
Nginx 0.5.4 (used as load balancer)
Squid-2.6.stable6 (provides professional caching while doing reverse proxy function）
second, compile and install
I.) Installation of Nginx
1.) Installation
The Nginx pronunciation is [engine x], which was established by the Russian Igor Sysoev Project, based on the BSD license. It is said that he was one of the members of F5, English homepage:/http Nginx. Net. Some of Russia's big Web sites have been using it for more than two years, and have been remarkable.
The compiler parameters of Nginx are as follows:
[Root@localhost]#./configure--prefix=/usr/local/server/nginx--with-openssl=/usr/include
--with-pcre=/usr/include/pcre/--with-http_stub_status_module--without-http_memcached_module
--without-http_fastcgi_module--without-http_rewrite_module--without-http_map_module
--without-http_geo_module--without-http_autoindex_module
Here, you need to explain, because Nginx configuration fileI want to use the regular, so I need pcre ModuleThe support. I have installed the RPM package for Pcre and Pcre-devel, but Ngxin does not find the. h/.so/.a/.la file correctly, so I am slightly flexible:
[Root@localhost] #mkdir/usr/include/pcre/.libs/
[Root@localhost] #cp/usr/lib/libpcre.a/usr/include/pcre/.libs/libpcre.a
[Root@localhost] #cp/usr/lib/libpcre.a/usr/include/pcre/.libs/libpcre.la
Then, modify the Objs/makefile about 908 lines, commenting out the following:
./configure--disable-shared
Next, you will be able to perform the make and makes install normally.
2.) Modify the configuration file/usr/local/server/nginx/conf/nginx.conf
The following is my nginx.conf content, for reference only:

#启动进程

#全局错误 Logand PID File
