一、配置目标

1、通过lnmp完成基础环境的安装

通过lnmp安装后,相关软件的位置请参考其官方说明。安装后我单独通过气官方说明,升级了nginx的版本

2、配置nginx使之能满足php+java环境在一台机器上的复用

二、相关安装说明

1、将tomcat安装到/usr/local/tomcat6

2、将nginx安装到/usr/local/nginx

3、将java项目安装到tomcat6/webapps下

4、将php相关项目直接安装到/usr/local/下

三、相关配置说明

主要说明几个主配置文件的情况

1、nginx.conf

user www www;

worker_processes 1;

error_log /home/wwwlogs/nginx_error.log crit;

pid /usr/local/nginx/logs/nginx.pid;

#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 51200;

events
{
use epoll;
worker_connections 51200;
}
#fastcgi参数的配置很重要。对性能影响较大
http
{
include mime.types;
default_type application/octet-stream;

server_names_hash_bucket_size 128;
client_header_buffer_size 32k;
large_client_header_buffers 4 32k;
client_max_body_size 50m;

sendfile on;
tcp_nopush on;

keepalive_timeout 60;

tcp_nodelay on;

fastcgi_connect_timeout 300;
fastcgi_send_timeout 300;
fastcgi_read_timeout 300;
fastcgi_buffer_size 256k;
fastcgi_buffers 8 256k;
fastcgi_busy_buffers_size 512k;
fastcgi_temp_file_write_size 512k;

gzip on;
gzip_min_length 1k;
gzip_buffers 4 16k;
gzip_http_version 1.0;
gzip_comp_level 2;
gzip_types text/plain application/x-javascript text/css application/xml;
gzip_vary on;

#limit_zone crawler $binary_remote_addr 10m;

#log format
log_format access '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" $http_x_forwarded_for';

#核心指出了各个域名的配置文件位置,在nginx/conf/vhost目录中
 include vhost/*.conf;

}

2、vhost(在nginx.conf指明了相关域名对应的配置文件位置)

(1)、php项目配置:文件名称shequ.jiuchongju.com.conf

这里我将一个域名的相关配置在这里展示:shequ.jiuchongju.com

server
{
listen 80;
server_name shequ.jiuchongju.com;
index index.html index.htm index.php;
root /usr/local/discuzx/upload;

location ~ .*\.(php|php5)?$
{
try_files $uri =404;
fastcgi_pass unix:/tmp/php-cgi.sock;
fastcgi_index index.php;
include fcgi.conf;
}

location /status {
stub_status on;
access_log off;
}

location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
{
expires 30d;
}

location ~ .*\.(js|css)?$
{
expires 12h;
}

access_log /home/wwwlogs/access.log access;
}

(2)、java项目配置:文件名称www.quickbook.cn.conf

这里我指定了一个java项目的配置  www.quickbook.cn

server { 
listen 80; 
server_name www.quickbook.cn; 

#charset koi8-r; 

access_log logs/dev/null; 

root /usr/local/tomcat6/webapps/quickbook/; 

#将请求反向代理到tomcat应用服务器上了

 location / { 

index index.jsp index.html index.htm ; 

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 10m; 
client_body_buffer_size 128k; 
proxy_buffers 32 4k; 
proxy_connect_timeout 3; 
proxy_send_timeout 30; 
proxy_read_timeout 30; 
proxy_pass http://127.0.0.1:8080; 
}

}

三、总结

1、主要是nginx将各个子域名的配置放到conf/vhost中独立处理

2、每个vhost下的配置文件都独立生效

3、nginx只是将请求转发到后端的应用服务器上

4、启动的时候需要按照如下次序启动

(1)、启动mysql数据库

(2)、启动tomcat

(3)、启动nginx
