一：Nginx+Tomcat的動靜分離
所謂動靜分離就是通過nginx（或apache等）來處理用戶端請求的圖片、html等靜態的文件，tomcat（或weblogic）處理jsp、do等動態文件，從而達到動靜頁面訪問時通過不同的容器來處理。
nginx處理靜態頁面效率遠高于tomcat，而tomcat擅長動態頁面處理，這樣一來就能更好的提高并發，處理性能。

1.主機
centos6.4?IP:10.10.54.157
?
2.在此主機上安裝nginx，及兩個tomcat，nginx的反向代理功能可以把用戶請求負載到tomcat上
nginx使用80端口，兩個tomcat分別使用8080，9080端口
目的：當訪問10.10.54.157這臺服務器時，靜態頁面由nginx處理，動態頁面由tomcat處理
?
3.軟件下載
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運行環境
wget?http:
//apache
.dataguru.cn
/tomcat/tomcat-7/v7
.0.52
/bin/apache-tomcat-7
.0.52.
tar
.gz

#nginx使用fpm的方式調用php
#php5.4以后版本中已經支持php-fpm,所以只需要在php編譯參數里指定--enable-fpm即可
1.編譯安裝
shell>?yum??-y?
install
?
zlib-devel?pcre-devel?openssl-devel????
#nginx依賴包
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.啟動nginx
shell>?
/usr/local/nginx/sbin/nginx
?
-c?
/usr/local/nginx/conf/nginx
.conf
##添加nginx支持php
3.首先為php創建配置文件?
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.啟動php-fpm????
shell>?
/usr/local/php/sbin/php-fpm

export
?
JAVA_HOME=
"/usr/java/jdk1.7.0_51"
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??
#顯示版本說明成功
java?version
"1.7.0_45"

1.解壓
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啟動腳本
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配置用戶管理(可以不設置)
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"
/>???
#用戶名和密碼都為tomcat
-----------------------------------------
?
【tomcat1?and?tomcat2】
4.重啟tomcat
shell>?
/etc/init
.d
/tomcat
?
stop
shell>?
/etc/init
.d
/tomcat
?
start

//測試
1.瀏覽器訪問10.10.54.157 默認顯示nginx根目錄下的index.php頁面
2.瀏覽器訪問10.10.54.157/index.jsp 瀏覽器跳轉到tomcat默認首頁，在首頁點擊Server Status頁面，并刷新瀏覽器，可以看到頁面在兩個tomcat之間切換
