Linux Cache

Alternative PHP Cache (APC) 是一个开放自由的PHP opcode 缓存。它的目标是提供一个自由、 开放，和健全的框架用于缓存和优化PHP的中间代码。

eAccelerator is a free open-source PHP accelerator & optimizer. It increases the performance of PHP scripts by caching them in their compiled state, so that the overhead of compiling is almost completely eliminated. It also optimizes scripts to speed up their execution. eAccelerator typically reduces server load and increases the speed of your PHP code by 1-10 times.

eAccelerator stores compiled PHP scripts in shared memory and executes code directly from it. It creates locks only for a short time, while searching for a compiled PHP script in the cache, so one script can be executed simultaneously by several engines. Files that can’t fit in shared memory are cached on disk only.

eAccelerator was born in December 2004 as a fork of the Turck MMCache project. Turck MMCache was created by Dmitry Stogov and much of the eAccelerator code is still based on his work.

使用两台apache主机与一台nginx主机分别处理动态和静态文件，同时负载均衡apache主机

动态文件需要服务器额外处理后通过浏览器将结果返回给客户
静态文件不需要额外服务器处理可以直接将结果给客户

通过命令行进行IP绑定

[root@localhost network-scripts]# ifconfig eth0:3 192.168.244.140 netmask 255.255.255.0
 [root@localhost network-scripts]# ifconfig eth0:3

基于IP地址的虚拟主机配置

[root@localhost ~]# cd /usr/local/nginx/conf/

[root@localhost conf]# mkdir ../html/ipv1
[root@localhost conf]# touch ../html/ipv1/index.html
[root@localhost conf]# echo “IP based virtual host 1 OK”>../html/ipv1/index.html
[root@localhost conf]# mkdir ../html/ipv2
[root@localhost conf]# touch ../html/ipv2/index.html
[root@localhost conf]# echo “IP based virtual host 2 OK”>../html/ipv2/index.html

在nginx配置文件中添加基于IP的虚拟机主机配置
[root@localhost conf]# vi nginx.conf
server {
listen       192.168.244.136:80;
server_name  192.168.244.136;
access_log   logs/ipv1_access.log;

location / {
root   html/ipv1;
index  index.html index.htm;
}
}

server {
listen       192.168.244.138:80;
server_name  192.168.244.138;
access_log   logs/ipv2_access.log;

location / {
root   html/ipv2;
index  index.html index.htm;
}
}

确认修改后的配置文件语法正确性
[root@localhost conf]# nginx -t -c /usr/local/nginx/conf/nginx.conf
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@localhost conf]#

基于主机名的虚拟机主机配置

建立测试目录及文件

[root@localhost conf]# mkdir ../html/nv1
[root@localhost conf]# touch ../html/nv1/index.html
[root@localhost conf]# echo “Name based virtual host 1 OK”>../html/nv1/index.html
[root@localhost conf]# mkdir ../html/nv2
[root@localhost conf]# touch ../html/nv2/index.html
[root@localhost conf]# echo “Name based virtual host 2 OK”>../html/nv2/index.html
[root@localhost conf]# mkdir ../html/nv3
[root@localhost conf]# touch ../html/nv3/index.html
[root@localhost conf]# echo “Name based virtual host 3 OK”>../html/nv3/index.html

在nginx配置文件中添加基于主机名的虚拟机主机配置
server {
listen       80;
server_name  nv1.linuxcache.net;
access_log   logs/nv1_access.log;

location / {
root   html/nv1;
index  index.html index.htm;
}
}

server {
listen       80;
server_name  nv2.linuxcache.net nv3.linuxcache.net;
access_log   logs/nv2_access.log;

location / {
root   html/nv2;
index  index.html index.htm;
}
}

server {
listen       80;
server_name  *.linuxcache.cn;
access_log   logs/nv3_access.log;

location / {
root   html/nv3;
index  index.html index.htm;
}
}

修改Windows客户机主机文件将测试域名指向虚拟机IP地址
