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、什麼是動靜分離
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的動態請求都交給後面的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" $http_x_forwarded_for';
- access_log /usr/local/nginx/logs/access.log access;
- }
- server
- {
- listen 80;
- server_name status.test1.dl.com;
- location / {
- stub_status on;
- access_log off;
- }
- }
- }
2、安裝、配置tomcat
先安裝jdk
在/etc/profile里設置環境變數
- wget http://download.oracle.com/otn-pub/java/jdk/7u3-b04/jdk-7u3-linux-x64.rpm
- chmod 755 jdk-7u3-linux-x64.rpm
- rpm -ivh jdk-7u3-linux-x64.rpm
然後在source /etc/profile使這個改變生效
- JAVA_HOME=/usr/java/jdk1.7.0
- CLASSPATH=$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
之後打開http://localhost:8080就能看到tomcat的默認界面了 下面我們來修改tomcat的首頁 我在$tomcat/webapps/下建了個html目錄作為我網站的默認目錄,在html中有一個index.html文件,該文件要作為我網站的默認主頁. ,修改$tomcat/conf/server.xml文件.
- /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>標籤之間添加上:
path是說明虛擬目錄的名字,如果你要只輸入ip地址就顯示主頁,則該鍵值留為空;
- <Context path="" docBase="html" debug="0" reloadable="true" />
然後,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:
修改完成之後,重啟tomcat即可看到index.html里的內容 tomcat伺服器的ip為10.1.88.168
- < welcome-file>html</welcome-file>
在test4建立test.jsp、test1.do文本,內容如下
tomcat的首頁內容 test.jsp內容 test1.do內容nginx的首頁內容
在nginx里查看動態請求 nginx處理test1.do現在nginx tomcat就實現了動靜分離技術,如果大家還有什麼疑問,請聯繫我,我會及時的幫忙解答.
