最近公司的項目都完成了，工作很清閑，處理每天的日常巡檢工作外，我還整理了一下以前學習的筆記，現在把我的筆記share給大家。
一、什么是動靜分離
本文的動靜分離主要是通過nginx+tomcat來實現，其中nginx處理圖片、html等靜態的文件，tomcat處理jsp、do等動態文件。
二、結構圖
三、安裝
1、安裝、配置nginx
下載nginx與pcre（如果需要使用正則，需要安裝pcre）
wget http://blog.s135.com/soft/linux/nginx_php/nginx/nginx-0.8.46.tar.gz
wget http://blog.s135.com/soft/linux/nginx_php/pcre/pcre-8.10.tar.gz
安裝pcre
tar zxvf pcre-8.10.tar.gz cd pcre-8.10/ ./configure make make install cd ..
安裝nginx
tar zxvf nginx-0.8.46.tar.gz cd nginx-0.8.46/ ./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module make make install
nginx.conf配置
user www www; worker_processes 8; error_log /usr/local/nginx/logs/nginx_error.log crit; pid /usr/local/nginx/nginx.pid; worker_rlimit_nofile 65535; events { use epoll; worker_connections 65535; } http { include mime.types; default_type application/octet-stream; #charset gb2312; server_names_hash_bucket_size 128; client_header_buffer_size 32k; large_client_header_buffers 4 32k; client_max_body_size 8m; 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 64k; fastcgi_buffers 4 64k; fastcgi_busy_buffers_size 128k; fastcgi_temp_file_write_size 128k; 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 $binary_remote_addr 10m; server { listen 80; server_name test1.dl.com; ####test1.dl.com的ip為10.1.88.176 index index.html index.htm index.php; root /usr/local/nginx/html; #limit_conn crawler 20; location ~ .*\.(php|php5)?$ { #fastcgi_pass unix:/tmp/php-cgi.sock; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; include fastcgi.conf; } location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$ ###所以的靜態文件人gif、jpg等都在本地打開，存放的目錄為/usr/local/nginx/html，保存時間為30天 { root /usr/local/nginx/html; expires 30d; } location ~ (\.jsp)|(\.do)$ ###所以jsp、do的動態請求都交給后面的tomcat處理 { proxy_pass http://10.1.88.168:8080; proxy_redirect off; proxy_set_header HOST $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; client_max_body_size 10m; client_body_buffer_size 128k; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; } location ~ .*\.(js|css)?$ { expires 1h; } log_format access '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" $http_x_forwarded_for'; access_log /usr/local/nginx/logs/access.log access; } server { listen 80; server_name status.test1.dl.com; location / { stub_status on; access_log off; } } }
2、安裝、配置tomcat
先安裝jdk
wget http://download.oracle.com/otn-pub/java/jdk/7u3-b04/jdk-7u3-linux-x64.rpm chmod 755 jdk-7u3-linux-x64.rpm rpm -ivh jdk-7u3-linux-x64.rpm
JAVA_HOME=/usr/java/jdk1.7.0 CLASSPATH=$JAVA_HOME/lib:$JAVA_HOME/jre/lib PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin export PATH CLASSPATH JAVA_HOME
安裝tomcat
wget http://mirror.bjtu.edu.cn/apache/tomcat/tomcat-7/v7.0.25/bin/apache-tomcat-7.0.25.tar.gz tar zxvf apache-tomcat-7.0.25.tar.gz cp -R apache-tomcat-7.0.25 /usr/local/tomcat
啟動tomcat
/usr/local/tomcat/bin/startup.sh
…… <engine name="Catalina" defaultHost="localhost"> <host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false"> …… <host> </engine> ……
在<host></host>標簽之間添加上：
<Context path="" docBase="html" debug="0" reloadable="true" />
然后，修改$tomcat/conf/web.xml文件。在web.xml文件中，有一段如下：
<welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> </welcome-file-list>
在<welcome-file-list>與<welcome-file>index.html</welcome-file>之間添加上：
<welcome-file>html</welcome-file>
在test4建立test.jsp、test1.do文本，內容如下

現在nginx+tomcat就實現了動靜分離技術，如果大家還有什么疑問，請聯系我，我會及時的幫忙解答。
