Nginx Web服务器目前在IT企业中应用最广泛,为什么它会如此让人热爱呢,因为它的高性能、稳定性,而且越来越发展,那Nginx在企业中是如何来应用的呢?Nginx动静分离是如何来配置的呢,今天我们将跟大家一起来构建一个Nginx动静分离的架构。
一、实践环境:
系统版本:CentOS6.0 X86_64 Nginx版本:Nginx-1.2.6 Tomcat版本:Tomcat-6.0.18
二、Nginx安装:
实际环境中安装Nginx,首先需要安装pcre库,然后再安装Nginx:
#安装pcre支持rewrite库,也可以安装源码,注*安装源码时,指定pcre路径为解压源码的路径,而不是编译后的路径,否则会报错。
yum install pcre-devel pcre -y #下载Nginx源码包 cd /usr/src ;wget -c http://nginx.org/download/nginx-1.2.6.tar.gz #解压Nginx源码包 tar -xzf nginx-1.2.6.tar.gz #进入解压目录,然后sed修改Nginx版本信息为TDTWS cd nginx-1.2.6 ; sed -i -e ‘s/1.2.6//g‘ -e ‘s/nginx\//TDTWS/g‘ -e ‘s/"NGINX"/"TDTWS"/g‘ src/core/nginx.h #预编译Nginx ./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module #.configure预编译成功后,执行make命令进行编译 make #make执行成功后,执行make install 正式安装 make install
#自此Nginx安装完毕!!!
三、配置Nginx:
这里鉴于我的51CTO博客已经有Tomcat安装和配置了,这里忽略,只配置Nginx。
#进入Nginx应用目录
cd /usr/local/nginx/conf #备份原nginx.conf文件 mv nginx.conf nginx.bak
创建 vi nginx.conf ,并写入如下内容:
user www www; worker_processes 8; worker_cpu_affinity 00000001 00000010 00000100 00001000 00010000 00100000 01000000 10000000; pid /usr/local/nginx/nginx.pid; worker_rlimit_nofile 102400; events { use epoll; worker_connections 102400; } http { include mime.types; default_type application/octet-stream; fastcgi_intercept_errors on; charset utf-8; server_names_hash_bucket_size 128; client_header_buffer_size 4k; large_client_header_buffers 4 32k; client_max_body_size 300m; sendfile on; tcp_nopush on; keepalive_timeout 60; tcp_nodelay on; client_body_buffer_size 512k; proxy_connect_timeout 5; proxy_read_timeout 60; proxy_send_timeout 5; proxy_buffer_size 16k; proxy_buffers 4 64k; proxy_busy_buffers_size 128k; proxy_temp_file_write_size 128k; gzip on; gzip_min_length 1k; gzip_buffers 4 16k; gzip_http_version 1.1; gzip_comp_level 2; gzip_types text/plain application/x-javascript text/css application/xml; gzip_vary on; ###2012-12-19 change nginx logs log_format main ‘$http_x_forwarded_for - $remote_user [$time_local] "$request" ‘ ‘$status $body_bytes_sent "$http_referer" ‘ ‘"$http_user_agent" $request_time $remote_addr‘; #这里为后端服务器wugk应用集群配置,根据后端实际情况修改即可,tdt_wugk为负载均衡名称,可以任意指定 #但必须跟vhosts.conf虚拟主机的pass段一致,否则不能转发后端的请求。 upstream tdt_wugk { server 10.10.141.30:8080 weight=1max_fails=2fail_timeout=30s; server 10.10.141.30:8081 weight=1max_fails=2fail_timeout=30s; server 10.10.141.31:8080 weight=1max_fails=2fail_timeout=30s; server 10.10.141.31:8081 weight=1max_fails=2fail_timeout=30s; server 10.10.141.32:8080 weight=1max_fails=2fail_timeout=30s; server 10.10.141.32:8081 weight=1max_fails=2fail_timeout=30s; } #这里为后端APP应用负载均衡配置,根据后端实际情况修改即可。tdt_app为负载均衡名称,可以任意指定 upstream tdt_app { server 10.10.141.40:8080 weight=1max_fails=2fail_timeout=30s; server 10.10.141.40:8081 weight=1max_fails=2fail_timeout=30s; server 10.10.141.41:8080 weight=1max_fails=2fail_timeout=30s; server 10.10.141.41:8081 weight=1max_fails=2fail_timeout=30s; server 10.10.141.42:8080 weight=1max_fails=2fail_timeout=30s; server 10.10.141.42:8081 weight=1max_fails=2fail_timeout=30s; } #include引用vhosts.conf,该文件主要用于配置Nginx 虚拟主机 include vhosts.conf; } 如上nginx.conf配置完毕,继续配置nginx虚拟主机,继续在当前目录创建vhosts.conf vi vhosts.conf 内容如下: ####www.wuguangke.cn server { listen 80; server_name www.wuguangke.cn; index index.html index.htm; #配置发布目录为/data/www/wugk root /data/www/wugk; location / { proxy_next_upstream http_502 http_504 error timeout invalid_header; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_pass http://tdt_wugk; expires 3d; } #动态页面交给http://tdt_wugk,也即我们之前在nginx.conf定义的upstream tdt_wugk 均衡 location ~ .*\.(php|jsp|cgi)?$ { proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_pass http://tdt_wugk; } #配置Nginx动静分离,定义的静态页面直接从Nginx发布目录读取。 location ~ .*\.(html|htm|gif|jpg|jpeg|bmp|png|ico|txt|js|css)$ { root /data/www/wugk; #expires定义用户浏览器缓存的时间为3天,如果静态页面不常更新,可以设置更长,这样可以节省带宽和缓解服务器的压力 expires 3d; } #定义Nginx输出日志的路径 access_log /data/logs/nginx_wugk/access.log main; error_log /data/logs/nginx_wugk/error.log crit; } ##########chinaapp.sinaapp.com 2012-12-19 server { listen 80; server_name chinaapp.sinaapp.com; index index.html index.htm; root /data/www; location / { proxy_next_upstream http_502 http_504 error timeout invalid_header; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_pass http://tdt_app; expires 3d; } location ~ .*\.(php|jsp|cgi)?$ { proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_pass http://tdt_app; } location ~ .*\.(html|htm|gif|jpg|jpeg|bmp|png|ico|txt|js|css)$ { root /data/www/app; expires 3d; } access_log /data/logs/nginx_app/access.log main; error_log /data/logs/nginx_app/error.log crit; }
四、部署测试:
后端配置好Tomcat服务,并启动,发布的程序需同步到Nginx的/data/www对应的目录,因为配置动静分离后,用户请求你定义的静态页面,默认会去nginx的发布目录请求,而不会到后端请求,所以这时候你要保证后端跟前端的程序保持一致,可以使用Rsync做服务端自动同步或者使用NFS、MFS分布式共享存储。
#检查Nginx配置文件是否配置正确,提示Ok and successful表示正确,如下:
[root@WEB-11-151 ~]# /usr/local/nginx/sbin/nginx -t
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
#启动Nginx服务
/usr/local/nginx/sbin/nginx
#查看Nginx进程是否启动
ps -ef |grep nginx
自此,Nginx动静分离配置完毕,欢迎大家一起交流!
