一，web服務(wù)器小論

　　以前的公司使用的web服務(wù)器是tomcat（tomcat+apache作集群）,現(xiàn)在的公司是一家互聯(lián)網(wǎng)公司，采用的架構(gòu)是resin+nginx作集群(resin比tomcat快？還有待以后章節(jié)比較討論)，

集群配置服務(wù)器說明：

　　　 1),serve1:127.0.0.1:8080

　2), serve2:127.0.0.1:8081

　3), nginx:127.0.0.1:80

集群配置服務(wù)器說明：

　　　 1),serve1:127.0.0.1:8080

　2), serve2:127.0.0.1:8081

　3), nginx:127.0.0.1:80

二，配置resin服務(wù)器

　　(注：resin4之前，可以搭一個服務(wù)器，在<cluster></cluster>中配置多個server實(shí)例，通過實(shí)例啟動，4.0之后就不可以了，要有專業(yè)版才能實(shí)現(xiàn))

　　在安裝resin之前，必須先安裝完jvm環(huán)境。

　　serve1:127.0.0.1:8080--->

1，安裝resin-4.0.*.tar.gz包

Java代碼

1. shell $> tar zxvf resin-4.0.23.tar.gz
2. shell $> cd resin-4.0.23
3. shell $> ./configure --prefix=/usr/resin/resinserver1/resinserver1/
4. shell $> make
5. shell $> make install

shell $> tar zxvf resin-4.0.23.tar.gz shell $> cd resin-4.0.23 shell $> ./configure --prefix=/usr/resin/resinserver1/resinserver1/ shell $> make shell $> make install

　　2，配置resin.conf文件

　shell $> cd /usr/resin/resinserver1/resinserver1/

Java代碼

1. shell $> cd conf
2. shell $> vim resin.conf
3. ## 查找 <http address="*" port="8080"/>
4. ## 注釋掉 <!--http address="*" port="8080"/-->
5. ## 查找 <server id="" address="127.0.0.1" port="6800">
6. ## 替換成
7. <server id="resinserver1" address="127.0.0.1" port="6800">
8. <!--<strong>兩臺服務(wù)器配置不同的watchdog端口，否則會出現(xiàn)異常</strong>-->
9. <watchdog-port>6700</watchdog-port>
10. <http id="" port="8080"/>
11. </server>
12. ###重啟 resin 服務(wù)#####
13. shell $> cd ../bin
14. shell $>./resin.sh -server resinserver1 start

shell $> cd conf shell $> vim resin.conf ##  查找     <http address="*" port="8080"/> ## 注釋掉 <!--http address="*" port="8080"/--> ## 查找      <server id="" address="127.0.0.1" port="6800"> ## 替換成         <server id="resinserver1" address="127.0.0.1" port="6800">      <!--兩臺服務(wù)器配置不同的watchdog端口，否則會出現(xiàn)異常-->     <watchdog-port>6700</watchdog-port>     <http id="" port="8080"/>     </server> ###重啟  resin 服務(wù)##### shell $> cd ../bin shell $>./resin.sh -server resinserver1 start 

serve1:127.0.0.1:8081--->

---1,

Java代碼

1. shell $> tar zxvf resin-4.0.23.tar.gz
2. shell $> cd resin-4.0.23
3. shell $> ./configure --prefix=/usr/resin/resinserver2/resinserver2/
4. shell $> make
5. shell $> make install

shell $> tar zxvf resin-4.0.23.tar.gz shell $> cd resin-4.0.23 shell $> ./configure --prefix=/usr/resin/resinserver2/resinserver2/ shell $> make shell $> make install

2,配置resin

shell $> cd conf

Java代碼

1. shell $> vim resin.conf
2. ## 查找 <http address="*" port="8080"/>
3. ## 注釋掉 <!--http address="*" port="8080"/-->
4. ## 查找 <server id="" address="127.0.0.1" port="6800">
5. ## 替換成
6. <server id="resinserver2" address="127.0.0.1" port="6801">
7. <!--兩臺服務(wù)器配置不同的watchdog端口-->
8. <watchdog-port>6701</watchdog-port>
9. <http id="" port="8081"/>
10. </server>
11. ###重啟 resin 服務(wù)#####
12. shell $> cd ../bin
13. shell $>./resin.sh -server resinserver2 start

shell $> vim resin.conf ##  查找     <http address="*" port="8080"/> ## 注釋掉 <!--http address="*" port="8080"/--> ## 查找      <server id="" address="127.0.0.1" port="6800"> ## 替換成         <server id="resinserver2" address="127.0.0.1" port="6801">      <!--兩臺服務(wù)器配置不同的watchdog端口-->     <watchdog-port>6701</watchdog-port>     <http id="" port="8081"/>     </server> ###重啟  resin 服務(wù)##### shell $> cd ../bin shell $>./resin.sh -server resinserver2 start

通過以上配置，開啟兩臺resin服務(wù)器,接下來就是配置nginx

　三，nginx的配置

nginx安裝需要以下軟件包安裝

　　1,nginx-1.1.5.tar.gz

2,tbje-nginx-upstream-jvm-route-6016b39.tar.gz

3,openssl-1.0.0e.tar.gz(OPENSSL不需要編譯安裝，只需要解壓出來就行)

　　分別解壓以上程序...

Java代碼

1. shell $> cd nginx-1.1.5
2. shell $> patch -p0 < ../tbje-nginx-upstream-jvm-route-6016b39/jvm_route.patch
3. shell $> useradd www
4. shell $> ./configure --user=www --group=www --prefix=/usr/nginx/nginxserver --with-http_stub_status_module --with-http_ssl_module=/usr/nginx/openssl-1.0.0e --add-module=/usr/nginx/tbje-nginx-upstream-jvm-route-6016b39
5. shell $> make
6. shell $> make install

shell $> cd nginx-1.1.5 shell $> patch -p0 < ../tbje-nginx-upstream-jvm-route-6016b39/jvm_route.patch shell $> useradd www shell $> ./configure --user=www --group=www --prefix=/usr/nginx/nginxserver --with-http_stub_status_module --with-http_ssl_module=/usr/nginx/openssl-1.0.0e  --add-module=/usr/nginx/tbje-nginx-upstream-jvm-route-6016b39 shell $> make shell $> make install 

到nginxserver/sbin目錄下，，運(yùn)行./nginx　訪問http://127.0.0.1 出現(xiàn)“webcome to nginx”代表nginx安裝成功

　　四，配置集群

　　　打開nginxserver/conf/nginx.conf文件。

Java代碼

nginx命令：

Java代碼

1. start nginx 開啟nginx
2. 
   
3. Nginx -s stop 快速關(guān)閉Nginx，可能不保存相關(guān)信息，并迅速終止web服務(wù)。（quick exit）
4. Nginx -s quit 平穩(wěn)關(guān)閉Nginx，保存相關(guān)信息，有安排的結(jié)束web服務(wù)。（graceful exit）
5. Nginx -s reload 因改變了Nginx相關(guān)配置，需要重新加載配置而重載。（changing configuration，start a new worker,quitting an old worker gracefully.)
6. Nginx -s reopen 重新打開日志文件。(reopenging log files)
