为什么80%的码农都做不了架构师？>>> 
1，单ip多域名訪問不同網站，並且限制用戶使用IP訪問方法;
Apche httpd 在conf.d或者conf 文件夹下建立新的配置档案

}2，rewrite 重寫示例
RewriteEngine on
RewriteCond %{SERVER_PORT} 80
RewriteRule ^.*$ https://%{SERVER_NAME}%{REQUEST_URI} [L,R]
RewriteLog /var/log/httpd/rewrite.log
RewriteLogLevel 103，mod_jk轉發Tomcat配置
a.新建mod_jk.conf文件
vim conf.d/mod_jk.conf
LoadModule jk_module modules/mod_jk-1.2.31-httpd-2.2.x.so
JkWorkersFile conf.d/workers.properties
JkLogFile ""logs/mod_jk.log"
JkMount /* controller#指定那些请求交给tomcat处理,"controller"为在workers.propertise里指定的负载分配控制器名
4，将下载的JK插件mod_jk-1.2.31-httpd-2.2.x.so复制到Apache安装目录的modules目录下。
5，新建并编辑workers.properties文件，内容如下
#server
worker.list = controller
#========tomcat1========
worker.tomcat1.port=11009
worker.tomcat1.host=localhost
worker.tomcat1.type=ajp13
worker.tomcat1.lbfactor = 1
#========tomcat2========
worker.tomcat2.port=12009
worker.tomcat2.host=localhost
worker.tomcat2.type=ajp13
worker.tomcat2.lbfactor = 1
#========controller LB========
worker.controller.type=lb
worker.controller.balanced_workers=tomcat1,tomcat2,tomcat3
worker.controller.sticky_session=false
worker.controller.sticky_session_force=1
#worker.controller.sticky_session=1worker.tomcat1.lbfactor = 1 表示tomcat权重，越大表示分的请求越多；
这里可以配置任意多个Tomcat，此处配置了3个Tomat服务器，2个本地，1个远程，所以为了它们都能够顺利启动起来，本地的服务器端口都是不同的，如果Tomcat不再同一机器上，没必要改端口的。
tomcat实现访问不加项目名访问需要添加
6，Tomcat redis session 共享
redis安装测试环境为：
java version "1.7.0_79"
apache-tomcat-7.0.67
将这三个文件复制到tomcat lib目录下
commons-pool-1.6.jar
tomcat-redis-session-manager-1.2-tomcat-7.jar
jedis-2.1.0.jar
vim conf/context.xml 增加以下部分内容
这样就可以使用redis，但是在后续的测试中需要在项目中添加，在web 建立WEB-INF文件夹 建立web.xml文件 添加
Welcome to Tomcat
Welcome to Tomcat
7，另外一种方式实现session共享 通过cluster
vim conf/server.xml
注意当使用redis测试session共享时 最好不要设置jvmRoute 因为设置会导致redis 内存使用超过100%，暂时不知什么原因
vim conf/server.xml 添加一下集群配置部分
8，测试session共享之办法
1，在webapps下建立部署目录web 建立相应的主页index.jsp
<%@ page contentType="text/html; charset=GBK" %>
<%@ page import="java.util.*" %>
Cluster App Test
Server Info:
<%
out.println(request.getLocalAddr() + " : " + request.getLocalPort()+"
");%>
<%
out.println("
ID " + session.getId()+"
");
// 如果有新的 Session 属性设置
String dataName = request.getParameter("dataName");
if (dataName != null && dataName.length() > 0) {
String dataValue = request.getParameter("dataValue");
session.setAttribute(dataName, dataValue);
}
out.print("Session Cloumn");
Enumeration e = session.getAttributeNames();
while (e.hasMoreElements()) {
String name = (String)e.nextElement();
String value = session.getAttribute(name).toString();
out.println( name + " = " + value+"
");
System.out.println( name + " = " + value);
}
%>
Name:
Value:
在web 建立WEB-INF文件夹 建立web.xml文件 添加
Welcome to Tomcat
Welcome to Tomcat
或者使用另外一种jsp文件
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
Apache+tomcat负载均衡+redis会话管理
集群节点1
Session ID
<%= session.getId() %>
Created on
<%= session.getCreationTime() %>
分别设置集群节点1和节点2 测试；
9,Nginx+tomcat session
A,nginx 工作流程
B,下载相应版本的nginx 以及nginx sticky
此环境为：
nginx-1.4.7.tar.gz
nginx-sticky-module-1.1.tar.gz
yum -y install pcre-devel openssl-devel解压相应的软件包
安装nginx
./configure --prefix=/usr/local/nginx-1.4.7 --with-http_stub_status_module --with-http_ssl_module --with-http_realip_module --add-module=../nginx-sticky-module-1.1
make
make installC,nginx 的upstream使用sticky,如下
整个配置文件如下：
user nobody;
worker_processes 8;
error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
pid logs/nginx.pid;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log logs/access.log main;
sendfile on;
tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
gzip on;
upstream tomcat {
# sticky;
server 10.207.238.66:8080;
server 10.207.238.67:8080;
}
server {
listen 80;
server_name localhost;
location / {
root html;
index index.html index.htm;
proxy_pass http://tomcat;
proxy_set_header X-Real-IP $remote_addr;
client_max_body_size 100m;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}D,测试nginx sticky
测试还是依照上面方法,进行测试当不使用sticky参数是SESSION id是会频繁变动的，当使用参数时 一直就保持当前的session id
具体的过程不在重复；
E,nginx sticky其他语法
sticky [name=route] [domain=.foo.bar] [path=/] [expires=1h] [hash=index|md5|sha1] [no_fallback];
name: 可以为任何的string字符,默认是route
domain：哪些域名下可以使用这个cookie
path：哪些路径对启用sticky,例如path/test,那么只有test这个目录才会使用sticky做负载均衡
expires：cookie过期时间，默认浏览器关闭就过期，也就是会话方式。
no_fallbackup：如果设置了这个，cookie对应的服务器宕机了，那么将会返回502（bad gateway 或者 proxy error），建议不启用7、nginx sticky expires用法
upstream tomcat {
sticky expires=1h;
server 10.207.238.66:8080;
server 10.207.238.67:8080;
}启用了过期，cookie如下截图,cookie 1个小时才过期;
