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:10.10.54.157
2.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
|
//安装nginx，并配置nginx支持php

#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nginx
shell>
/usr/local/nginx/sbin/nginx
-c
/usr/local/nginx/conf/nginx
.conf
##添加nginx支持php
3.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

//安装JDK

shell> rpm -ivh jdk-7u51-linux-x64.rpm
shell>
vi
/etc/profile

export
JAVA_HOME=

export
CLASSPATH=
"$JAVA_HOME/lib:$JAVA_HOME/jre/lib"
export
PATH=
"$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$HOME/bin"
CATALINA_HOME=
"/usr/local/tomcat"
-----------------------
shell>
source
/etc/profile
shell> java -version
#显示版本说明成功
java version
"1.7.0_45"

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tomcat
shell>
/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
