今天完成的任务:

一:部署两台WEB，使用Nginx的Upstream来做负载。重新压测.

改变nginx.conf配置想让它生效而不停止服务,如下两种方式都可以:

1) nginx -t;  nginx -s reload
2) nginx -t;  kill -HUP 
nginx -t 检查nginx配置的语法,操作前都要检查一下,很重要,发现错误可及时修正.

以下是昨天配置时候的几个关键句

nginx-conf.d upstream tomcat_local 

proxy http://tomcat_local

http://tomcat_local/task-five

hosts 

upstream A{}

http://A  ?

下面是nginx.conf里面的具体配置

user www-data;

worker_processes auto;

pid /run/nginx.pid;

include /etc/nginx/modules-enabled/*.conf;

events {

worker_connections 768;

# multi_accept on;

}

# server_name_in_redirect off;

       # upstream www.dreamguys.org(这里可以将tomcat_local改成这个域名,后面不用proxy_set_header也可以直接访问)

         upstream tomcat_local {

             # server locahost:8090(加上这一段可以用来加上jetty做8090端口,配置成负载均衡的方式)

             server localhost:8080;

         }

include /etc/nginx/mime.types;

default_type application/octet-stream;

                # proxy_pass http://www.dreamguys.org

                proxy_pass http://tomcat_local;

                #下面这句配置在用tomcat_local这个化名是必须使用,不然服务器解析不到正确的地址

                proxy_set_header        Host            $host;

            }

     1.Java
     2.Maven
     3.svn/git
     4.eclipse/idea
     5.navicat

     6.Mysql

二. DB的读写

     1.关系型数据库
     2.简单的Sql语句
     3.Dal的设计和缓存
     4.Dao和Service
     5.DynamicSql

   3.stdout.log stderr.log

遇到的问题:

    在做Nginx+Tomcat的时候,一直存在以下问题,昨天都解决了

     浏览器输入域名显示的是Tomcat的官网首页,而不是自己项目首页.

       解决:在Tomcat中server.xml文件中,做如下蓝色部分配置

<Host name="localhost"  appBase="webapps"

            unpackWARs="true" autoDeploy="true">

        <!-- SingleSignOn valve, share authentication between web applications

             Documentation at: /docs/config/valve.html -->

            <Context

                 path=""

                 docBase="/usr/local/tomcat7/webapps/task-five"

                debug="0"

                reloadable="true"/>

        <!--

        <Valve className="org.apache.catalina.authenticator.SingleSignOn" />

        -->

        <!-- Access log processes all example.

             Documentation at: /docs/config/valve.html

             Note: The pattern used is equivalent to using pattern="common" -->

        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"

               prefix="localhost_access_log." suffix=".txt"

               pattern="%h %l %u %t &quot;%r&quot; %s %b" />

</Host>

收获:

    Nginx本身很灵活,需要多用才知道其中的各种功能.加油!

明年的计划:

    着手service和web的分离.
