一：Nginx+Tomcat的动静分离
所谓动静分离就是通过nginx（或apache等）来处理用户端请求的图片、html等静态的文件，tomcat（或weblogic）处理jsp、do等动态文件，从而达到动静页面访问时通过不同的容器来处理。
nginx处理静态页面效率远高于tomcat，而tomcat擅长动态页面处理，这样一来就能更好的提高并发，处理性能。

1.主机centos6.4 IP:10.10.54.1572.在此主机上安装nginx，及两个tomcat，nginx的反向代理功能可以把用户请求负载到tomcat上nginx使用80端口，两个tomcat分别使用8080，9080端口目的：当访问10.10.54.157这台服务器时，静态页面由nginx处理，动态页面由tomcat处理3.软件下载wget http://nginx.org/download/nginx-1.4.5.tar.gz
wget http://download.oracle.com/otn-pub/java/jdk/7u51-b13/jdk-7u51-linux-x64.rpm #jdk提供tomcat运行环境
wget http://apache.dataguru.cn/tomcat/tomcat-7/v7.0.52/bin/apache-tomcat-7.0.52.tar.gz

#nginx使用fpm的方式调用php#php5.4以后版本中已经支持php-fpm,所以只需要在php编译参数里指定--enable-fpm即可1.编译安装shell> yum -y install zlib-devel pcre-devel openssl-devel #nginx依赖包
shell> tar xvf nginx-1.4.5.tar.gz
shell> cd nginx-1.4.5
shell> ./configure --prefix=/usr/local/nginx --with-pcre --with-http_stub_status_module --user=apache --group=apache --with-http_ssl_module --with-http_gzip_static_module
shell> make && make install
2.启动nginxshell> /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
##添加nginx支持php3.首先为php创建配置文件 shell> cp php.ini-production /usr/local/php/php.ini
shell> mv /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
shell> ln -s /usr/local/php/bin/php /usr/bin/ 4.配置php-fpm.conf shell> vi /usr/local/php/etc/php-fpm.conf
-------------------------------- listen = /var/run/php-fpm.sock # 使用unix socket
-------------------------------- 5.启动php-fpm shell> /usr/local/php/sbin/php-fpm

1.解压shell> tar xvf apache-tomcat-7.0.52.tar.gz
shell> cp apache-tomcat-7.0.52 /usr/local/tomcat1
shell> cp apache-tomcat-7.0.52 /usr/local/tomcat2
shell> chown apache.apache /usr/local/tomcat1
shell> chown apache.apache /usr/local/tomcat2
【tomcat1 and tomcat2】2.制作tomcat启动脚本shell> cp catalina.sh /etc/init.d/tomcat1
shell> chmod +x /etc/init.d/tomcat1 shell> vim /etc/init.d/tomcat1
shell> chkconfig --add tomcat1【tomcat1 and tomcat2】3.tomcat配置用户管理(可以不设置)shell>cd /usr/local/tomcat1/conf
shell> vim tomcat-users.xml
----------------------------------------- <role rolename="manager-gui"/>
<role rolename="admin-gui"/>
<user username="tomcat" password="tomcat" roles="admin-gui,manager-gui"/>
#用户名和密码都为tomcat-----------------------------------------【tomcat1 and tomcat2】4.重启tomcatshell> /etc/init.d/tomcat stop
shell> /etc/init.d/tomcat start

//测试
1.浏览器访问10.10.54.157 默认显示nginx根目录下的index.php页面
2.浏览器访问10.10.54.157/index.jsp 浏览器跳转到tomcat默认首页，在首页点击Server Status页面，并刷新浏览器，可以看到页面在两个tomcat之间切换
