Apache+tomcat（linux推薦版）

聲明：進行apache+tomcat進行整合時，版本很重要
（儘量用以下版本，筆者當時安裝吃了不少虧，在網上下了多種版本的，現在總結如下）

一、apache的安裝
1.準備以下安裝包
apr-1.5.2.tar.gz
apr-util-1.5.4.tar.gz
pcre-8.37.tar.gz
httpd-2.4.3.tar.gz

2.安裝gcc，g++和make
#apt-get install gcc
#apt-get install make
#apt-get install g++

2.安裝apr
#tar xzvf apr-1.5.2.tar.gz
#cd apr-1.5.2
#./configure --prefix=/usr/local/apr-1.5.2
#make
#make install

3.安裝apr-util
#tar xzvf apr-util-1.5.4.tar.gz
#cd apr-util-1.5.4
#./configure --prefix=/usr/local/apr-util-1.5.4 --with-apr=/usr/local/apr-1.5.2
#make
#make install

4.安裝pcre
#tar xzvf pcre-8.37.tar.gz
#cd pcre-8.37/

#make
#make install

6.啓動httpd
#/usr/local/httpd-2.4.3/bin/apachectl start
AH00558: httpd: Could not reliably determine the server’s fully qualified domain name, using 127.0.1.1. Set the ‘ServerName’ directive globally to suppress this message
提示找不到服務器的域名，進行如下修改：
#vi /usr/local/httpd-2.4.3/conf/httpd.conf
…
#ServerName www.example.com:80
ServerName localhost:80 <= 增加該行
…
重啓服務器
#/usr/local/httpd-2.4.3/bin/apachectl restart

瀏覽器輸入以下url，出現it works!,代表安裝成功。
http://

二、tomcat安裝
1.準備以下安裝包
jdk-7u79-linux-x64.tar.gz
apache-tomcat-8.0.30.tar.gz

2.安裝jdk
#cd /usr/local
#tar xzvf /root/jdk-7u79-linux-x64.tar.gz
#vi /etc/profile
#文件最下方添加如下環境變量：
export JAVA_HOME=/usr/local/jdk1.7.0_79
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
立即使環境變量生效。
#source /etc/profile
確認安裝
#java -version
java version “1.7.0_79”
Java™ SE Runtime Environment (build 1.7.0_79-b15)
Java HotSpot™ 64-Bit Server VM (build 24.79-b02, mixed mode)

3.安裝tomcat
#cd /usr/local
#tar xzvf /root/apache-tomcat-8.0.30.tar.gz
啓動tomcat
#/usr/local/apache-tomcat-8.0.30/bin/startup.sh
Using CATALINA_BASE: /usr/local/apache-tomcat-8.0.30
Using CATALINA_HOME: /usr/local/apache-tomcat-8.0.30
Using CATALINA_TMPDIR: /usr/local/apache-tomcat-8.0.30/temp
Using JRE_HOME: /usr/local/jdk1.7.0_79
Using CLASSPATH: /usr/local/apache-tomcat-8.0.30/bin/bootstrap.jar:/usr/local/apache-tomcat-8.0.30/bin/tomcat-juli.jar
Tomcat started.
通過瀏覽器輸入以下url進入tomcat的管理頁面：
http://:8080/

三、整合apache和tomcat（mod_jk方式）
對於apache2.2之前的版本，只有一種整合選擇，那就是mod_jk,apache2.2開始，apache
已經將ajp模塊標準化，已經集成到apache內部，只要使用修改下配置文件就可以了。

1.準備以下安裝包
tomcat-connectors-1.2.42-src.tar.gz

2.安裝tomcat-connectors
#tar xzvf tomcat-connectors-1.2.42-src.tar.gz
#cd tomcat-connectors-1.2.42-src/native/
#./configure --with-apxs=/usr/local/httpd-2.4.3/bin/apxs
#make
#cp /root/tomcat-connectors-1.2.41-src/native/apache-2.0/mod_jk.so /usr/local/httpd-2.4.3/modules/

3.在httpd中創建mod_jk.conf配置文件
#vi /usr/local/httpd-2.4.3/conf/mod_jk.conf
#define the workers.properties file
JkWorkersFile /usr/local/httpd-2.4.3/conf/workers.properties

#where to put the jk logs
JkLogFile /usr/local/httpd-2.4.3/logs/mod_jk.log

#define jk log level
JkLogLevel info

#set log format
JkLogStampFormat “[%a %b %d %H:%M:%S %Y]”

#JkOptions indicate to send SSL KEY SIZE,
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories

JkRequestLogFormat set the request format
JkRequestLogFormat “%w %V %T”

#pass the servlet and jsp request to tomcat by ajp13 protocol
JkMount /servlet/* worker1
JkMount /*.jsp worker1

4.在httpd中創建workers.properties配置文件
#vi workers.properties
#Defining a worker named worker1 and of type ajp13
worker.list=worker1
#Set properties for worker1
worker.worker1.type=ajp13
worker.worker1.host=localhost
worker.worker1.port=8009
worker.worker1.lbfactor=50
worker.worker1.cachesize=10
worker.worker1.cache_timeout=600
worker.worker1.socket_keepalive=1
worker.worker1.socket_timeout=300

5.修改tomcat的server.xml文件
#vi /usr/local/apache-tomcat-8.0.30/conf/server.xml
在HOST段中加入如下內容：

其中docBase爲存放網頁的目錄。

6.修改httpd.conf
修改DocumentRoot和Directory，使它指向存放網頁的目錄。
#vi /usr/local/httpd-2.4.3/conf/httpd.conf
…
DocumentRoot “/usr/local/apache-tomcat-8.0.30/webapps/”
<Directory “/usr/local/apache-tomcat-8.0.30/webapps/”>
…

增加以下內容：
LoadModule jk_module modules/mod_jk.so

Include /usr/local/httpd-2.4.3/conf/mod_jk.conf

8.創建測試頁面。
在/usr/local/apache-tomcat-8.0.30/webapps/目錄下創建index.jsp和index.html

index.html:

<html>
	<body>
		<h1> 
			hello world!
		</h1>
	</body>
</html>

index.jsp:

<html>
<body>
    <center>Now time is: <%=new java.util.Date()%></center>
</body>
</html>

9.重啓tomcat和apache
#/usr/local/apache-tomcat-8.0.30/bin/shutdown.sh
#/usr/local/apache-tomcat-8.0.30/bin/startup.sh
#/usr/local/httpd-2.4.3/bin/apachectl restart

測試（.html文件爲靜態文件，.jsp文件爲動態文件）
tomcat是8080端口，apache是80端口
http：ip+端口/index.jsp (動態資源)
http：ip+端口/index.html (靜態資源)

那麼該如何進行判斷呢？
首先當tomcat運行時，apache應該既能訪問靜態頁面，也能訪問動態頁面，
當tomcat關掉時，apache應該只能訪問靜態頁面。這個可以作爲是否成功的判斷條件！
