apache+tomcat整合（一）

apache与tomcat整合的方式有多种方式，这里介绍mod_jk方式：

系统环境：

[root@ORACLE logs]# uname -a
Linux ORACLE 2.6.18-308.el5 #1 SMP Fri Jan 27 17:17:51 EST 2012 x86_64 x86_64 x86_64 GNU/Linux
[root@ORACLE logs]# cat /etc/redhat-release 
Red Hat Enterprise Linux Server release 5.8 (Tikanga)

软件环境：

apr-1.5.1.tar.gz

apr-util-1.5.4

libevent-2.0.22-stable.tar.gz

pcre-8.36.zip

httpd-2.2.29.tar.gz

tomcat-connectors-1.2.40-src.tar.gz

jdk-7u45-linux-x64.gz

apache-tomcat-6.0.43.tar.gz

1、安装apache

# 编译和安装 apr 1.5
cd srclib/apr
./configure --prefix=/usr/local/apr-httpd/
make
make install

# 编译和安装 apr-util 1.5
cd ../apr-util
./configure --prefix=/usr/local/apr-util-httpd/ --with-apr=/usr/local/apr-httpd/
make
make install

# 配置 httpd
cd ../../
./configure --with-apr=/usr/local/apr-httpd/ --with-apr-util=/usr/local/apr-util-httpd/ --prefix=/usr/local/apache2.2
make && make install

#如果需要自动加载一些模块，则进行如下编译：
./configure --prefix=/usr/local/apache --enable-so --enable-rewrite --enable-rewrite=shared --enable-proxy --enable-proxy=shared --enable-speling --enable-speling=shared --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util

　　

2、安装tomcat，前面我已介绍如何安装tomcat，这里不做介绍，请看前面我的博客

3、编译生成mod_jk

[root@ORACLE data]# tar xzvf tomcat-connectors-1.2.40-src.tar.gz
[root@ORACLE data]# cd tomcat-connectors-1.2.40-src
[root@ORACLE tomcat-connectors-1.2.40-src]# ls
conf  docs  HOWTO-RELEASE.txt  jkstatus  LICENSE  native  NOTICE  README.txt  support  tools  xdocs
[root@ORACLE tomcat-connectors-1.2.40-src]# cd native/
[root@ORACLE native]# ls
aclocal.m4  buildconf.sh  config.log     configure     iis       Makefile.am  README.txt  TODO.txt
apache-1.3  BUILDING.txt  config.nice    configure.ac  libtool   Makefile.in  scripts
apache-2.0  common        config.status  docs          Makefile  netscape     STATUS.txt
[root@ORACLE native]#./configure  --with apxs=/usr/local/apache2.2/bin/apxs
[root@ORACLE native]#make

4、在apache2.2的conf文件下中创建两个文件：

mod_jk.conf    workers.properties

[root@ORACLE native]# cd /usr/local/apache2.2/conf/
[root@ORACLE conf]# ls
extra  httpd.conf  magic  mime.types  mod_jk.conf  original  workers.properties

编辑mod_jk.conf配置文件：

[root@ORACLE conf]# cat mod_jk.conf 
JkWorkersFile /usr/local/apache2.2/conf/workers.properties

# Where to put jk logs
JkLogFile /usr/local/apache2.2/logs/mod_jk.log

# Set the jk log level [debug/error/info]
JkLogLevel info

# Select the 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"

# 将所有servlet 和jsp请求通过ajp13的协议送给Tomcat，让Tomcat来处理
JkMount /servlet/*  worker1
JkMount /*.jsp worker1

编辑workers.properties:

注意：worker1为tomcat的名字，等会配置tomcat时和这个名字一致

[root@ORACLE conf]# cat 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、再配置httpd.conf，作以下修改：
将Listen 80 修改为 Listen 127.0.0.1:80
将ServerName 修改为 ServerName LocalHost:80
在DirectoryIndex中添加 index.jsp
我的网页放在/var/www/html下，所以要修改DocumentRoot

Listen 80
ServerName localhost:80
DocumentRoot "/var/www/html"
<Directory "/var/www/html">
    AllowOverride None
    Order allow,deny
    Allow from all
    XBitHack on
</Directory>
<IfModule dir_module>
    DirectoryIndex index.html index.jsp
</IfModule>
#添加加载mod_jk模块的语句
LoadModule jk_module modules/mod_jk.so
Include /usr/local/apache2.2/conf/mod_jk.conf

6、修改tomcat server.xml配置文件：

＃在host段中加入context段，气质docBase为web目录
<Context path="" docBase="/var/www/html" debug="0" reloadable="true" crossContext="true"/>

添加engine:

 <Engine name="Catalina" defaultHost="localhost" jvmRoute="worker1">

7、重启apache和tomcat服务器

#开启tomcat服务
[root@ORACLE conf]# ../bin/catalina.sh start
Using CATALINA_BASE:   /usr/local/tomcat6.0
Using CATALINA_HOME:   /usr/local/tomcat6.0
Using CATALINA_TMPDIR: /usr/local/tomcat6.0/temp
Using JRE_HOME:        /usr/local/jdk1.7
Using CLASSPATH:       /usr/local/tomcat6.0/bin/bootstrap.jar
[root@ORACLE conf]# ps aux|grep java        
root      6159  156  4.3 519068 45072 pts/1    Sl   10:36   0:01 /usr/local/jdk1.7/bin/java -Djava.util.logging.config.file=/usr/local/tomcat6.0/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.endorsed.dirs=/usr/local/tomcat6.0/endorsed -classpath /usr/local/tomcat6.0/bin/bootstrap.jar -Dcatalina.base=/usr/local/tomcat6.0 -Dcatalina.home=/usr/local/tomcat6.0 -Djava.io.tmpdir=/usr/local/tomcat6.0/temp org.apache.catalina.startup.Bootstrap start
root      6170  0.0  0.0  61176   724 pts/1    R+   10:36   0:00 grep java

#开启apache服务：
apachectl -k start

8、验证：

[root@ORACLE conf]# curl -I http://127.0.0.1/index.jsp
HTTP/1.1 200 OK
Date: Fri, 03 Apr 2015 03:29:39 GMT
Server: Apache/2.2.29 (Unix) mod_jk/1.2.40
Set-Cookie: JSESSIONID=1B7E68B32F64A807AC695F13F2851E58.worker1; Path=/
Content-Length: 65
Content-Type: text/html

如上图，我们可以看到apache的版本号暴露了，所以，我们需要将apache的版本号隐藏起来。

更改配置文件httpd.conf，添加如下两行配置：

ServerSignature Off

ServerTokens Prod

ServerSignature出现在Apache所产生的像404页面、目录列表等页面的底部

ServerTokens目录被用来判断 Apache会在Server HTTP响应包的头部填充什么信息

重启apache服务

隐藏tomcat版本号信息：

• 到apache-tomcat安装目录下的lib子文件夹，找到catalina.jar这包，并进行解  unzip catalina.jar

• 解压之后进度到org/catalina/apache/util/目录下，编辑ServerInfo.properties

• vim /path/tomcat/lib/org/apache/catalina/util/ServerInfo.properties

  原有配置：
  server.info=Apache Tomcat/6.0.43
  server.number=6.0.43.0
  server.built=Nov 14 2014 10:04:27 UTC
  修改后：
  server.info=Apache Tomcat/X
  server.number=X
  server.built=X
  

• 修改配置文件之后，重新压缩catalina.jar文件：

• cp catalina.jar  catalina.jar.dat
  rm -f catalina.jar
  zip -r  catalina.jar META-INF
  

  　　

• tomcat报错时的显示页面显示：

• HTTP Status 404 - /index.jsp

  ---

  type Status report

  message /index.jsp

  description The requested resource is not available.

• Apache Tomcat/X

 打开tomcat访问日志：

#修改server.xml文件，增加如下一句
 <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"  
               prefix="localhost_access_log." suffix=".txt" pattern="common" resolveHosts="false"/>

　查看tomcat日志：
