简单配置Nginx前端处理静态文件,LiteSpeed后端处理动态文件

因为我用的LiteSpeed是免费版,连接数只有150的限制,虽然这150的链接也能应付日IP1W的 WordPress 的博客 ,但是网站的流量慢慢增加,不得不提准备,用Nginx 来跑静态文件,减少一些连接请求,何况用Nginx前端的话,负载能力都高点,速度应该也快点吧,所以,我又折腾起来了,然后做个简单记录,防止以后忘记啊,这个就不算什么教程了.
第一步,当然是安装LiteSpeed啦,请看这里:http://imcat.in/litespeed-mysql-php-install/

然后就是安装Nginx了

wget -c http://catlnmp.googlecode.com/files/pcre-8.01.tar.gz
tar zxvf pcre-8.01.tar.gz
cd pcre-8.01/
./configure
make && make install
cd ../



wget -c http://nginx.org/download/nginx-0.8.53.tar.gz
tar zxvf nginx-0.8.53.tar.gz
cd nginx-0.8.53/
./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module
make && make install
cd ../


接着就是关键了,建立一个放网站配置文件的目录和创建配置文件:

mkdir -p /usr/local/nginx/conf/servers
rm -rf /usr/local/nginx/conf/nginx.conf
vi /usr/local/nginx/conf/nginx.conf

内容为:

user www www;
worker_processes 1;
error_log /usr/local/nginx/logs/nginx_error.log crit;
pid /usr/local/nginx/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 1024;
events
{
use epoll;
worker_connections 1024;
}
http
{
include mime.types;
default_type application/octet-stream;
#charse gb2312;
server_names_hash_bucket_size 128;
client_header_buffer_size 128k;
large_client_header_buffers 4 256k;
client_max_body_size 16m;
sendfile on;
tcp_nopush on;
keepalive_timeout 60;
tcp_nodelay on;

gzip on;
gzip_min_length 1k;
gzip_buffers 4 16k;
gzip_http_version 1.1;
gzip_comp_level 9;
gzip_types text/plain application/x-javascript text/css application/xml;
gzip_vary on;
output_buffers 4 32k;
postpone_output 1460;

#limit_zone crawler $binary_remote_addr 10m;
include servers/*;
}


vi /usr/local/nginx/conf/proxy.conf


proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
client_max_body_size 50m;
client_body_buffer_size 256k;
proxy_connect_timeout 30;
proxy_send_timeout 30;
proxy_read_timeout 60;

proxy_buffer_size 4k;
proxy_buffers 4 32k;
proxy_busy_buffers_size 64k;
proxy_temp_file_write_size 64k;
proxy_next_upstream error timeout invalid_header http_500 http_503 http_404;
proxy_max_temp_file_size 128m;

#Nginx cache
client_body_temp_path client_body 1 2;
proxy_temp_path proxy_temp 1 2;

#client_body_temp_path /tmpfs/client_body_temp 1 2;
#proxy_temp_path /tmpfs/proxy_temp 1 2;
#fastcgi_temp_path /tmpfs/fastcgi_temp 1 2;


最后就是站点配置文件:

vi /usr/local/nginx/conf/servers/imcat.conf



server
{
listen 80;
server_name imcat.in www.imcat.in *.imcat.in;
index index.html index.htm ;
root /home/www/imcat/;
include proxy.conf;

location / {
location ~ .*\.(php|php5)?$ {
index index.php;
root /home/www/imcat/;
proxy_pass http://127.0.0.1:8080; #这里的IP是你的LiteSpeed在Listeners 设置的IP和端口,一定要相同
}

if ( !-e $request_filename) {
proxy_pass http://127.0.0.1:8080; #这里的IP是你的LiteSpeed在Listeners 设置的IP和端口,一定要相同
}

location ~* \.(jpg|jpeg|gif|png|swf|htm|html)$ {
if (-f $request_filename) {
root /home/www/imcat/;
expires 30d;
break;
}
}
location ~* \.(js|css)$ {
if (-f $request_filename) {
root /home/www/imcat/;
expires 1d;
break;
}
}
}

error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}


然后启动Nginx和LiteSpeed就OK了…
所有东西我都是自己Google来的,所以一些错误我还不会解决的,欢迎大家来交流经验啊…
