本文共 22751 字,大约阅读时间需要 75 分钟。

[b]前序:网上有很多资料都介绍了apache httpd + tomcat + openssl--集群、session共享与ssl的配置,作为一个入门新手,根本不懂得如何配置,才能达到以上目的;幸好网上资料较多,经过几天的努力终于配置成功,其中遇到的错误主要是linux虚拟机ip地址有问题与未安装C编译器GCC与Zlib软件,还有一个是JAP地址配置成了我们常用的8080地址-_-,少说废话,开始总结这份经验吧。[/b]
1.环境准备:
[list]
[*]linux虚拟机两个【一个也行,这是为了更好的测试】
[*]JDK1.7左右
[*]tomcat7.0两个以上:[url]http://tomcat.apache.org/download-70.cgi[/url]下载如图所示:
[img]http://dl2.iteye.com/upload/attachment/0097/6487/887f86a4-089c-318b-98c9-0c568af6b364.png[/img]
[*]httpd-2.2.27.tar.gz:[url]http://httpd.apache.org/download.cgi[/url]下载如图所示:
[img]http://dl2.iteye.com/upload/attachment/0097/6481/293b9f65-a50d-3286-90eb-ffaeb515a9f2.png[/img]
[*]openssl-1.0.1g.tar.gz:[url]http://www.openssl.org/source/openssl-1.0.1g.tar.gz[/url]
[/list]
2.错误集中地,你最好看到错误之后返回这里:
[list]
[*]ERROR1安装gcc:【yum install gcc】在服务器任意地方直接copy这段语句运行(它会问你y/N,回答它y)。
[color=red]错误为:configure: error: in `/root/httpd-2.2.27/srclib/apr':
configure: error: no acceptable C compiler found in $PATH
See `config.log' for more details
configure failed for srclib/apr[/color]
[*]ERROR2安装zlib:【yum install zlib-devel -y】在服务器任意地方直接copy这段语句运行。
[color=red]错误为:checking for zlib location... not found[/color][/list]
3.首先安装apache httpd,你需要按照如下方式进行(配置有可能出ERROR1与ERROR2,解决这两个错误之后请重新把配置语句执行一遍):
[list]
[*]使用root用户(最好是root)上传:httpd-2.2.27.tar.gz
[*]解压:tar -xvf httpd-2.2.27.tar.gz
[*]①配置:./configure --prefix=/usr/local/apache2 --enable-modules=so --enable-mods-shared=all --enable-proxy --enable-proxy-connect --enable-proxy-ftp --enable-proxy-http --enable-proxy-ajp --enable-proxy-balancer --enable-rewrite
[*]制作:make
[*]安装:make install
[*]Over,安装完成。
[/list]
4.配置你的两个tomcat:
[list]
[*]tomcat_A,配置server.xml(${tomcatHome}/conf/server.xml),我的配置是:
以上server.xml中,请重点关注以下两点:
⑴<Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat_A">
把jvmRoute改成你想象中的名字
⑵Cluster加上这个节点中的所有内容,address="auto"这个默认会读取你的本机IP地址,如果你的机器IP地址设置有问题,你可以自己手动修改成本机地址,如address="192.168.0.27"。
[*]tomcat_B,配置server.xml(${tomcatHome}/conf/server.xml),我的配置是:
以上配置,基本与tomcat_A一样,只是Engine节点的jvmRoute属性为:tomcat_B。
[*]好了,两个tomcat已经配置完成,如果你的两个tomcat在同一台机器上面,你得修改任意一个tomcat的所有端口号,以免端口冲突。
[/list]
5.配置apache httpd:
[list]
[*]配置httpd.conf文件(usr/local/apache2/conf),我的配置内容为:
#
# This is the main Apache HTTP server configuration file. It contains the
# configuration directives that give the server its instructions.
# See <URL:http://httpd.apache.org/docs/2.2> for detailed information.
# In particular, see
# <URL:http://httpd.apache.org/docs/2.2/mod/directives.html>
# for a discussion of each configuration directive.
#
# Do NOT simply read the instructions in here without understanding
# what they do. They're here only as hints or reminders. If you are unsure
# consult the online docs. You have been warned.
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path. If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so 'log/access_log'
# with ServerRoot set to '/www' will be interpreted by the
# server as '/www/log/access_log', where as '/log/access_log' will be
# interpreted as '/log/access_log'.
#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# Do not add a slash at the end of the directory path. If you point
# ServerRoot at a non-local disk, be sure to point the LockFile directive
# at a local disk. If you wish to share the same ServerRoot for multiple
# httpd daemons, you will need to change at least LockFile and PidFile.
#
ServerRoot "/usr/local/apache2"
#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses.
#
#Listen 12.34.56.78:80
Listen 8000
#
# Dynamic Shared Object (DSO) Support
#
# To be able to use the functionality of a module which was built as a DSO you
# have to place corresponding `LoadModule' lines at this location so the
# directives contained in it are actually available _before_ they are used.
# Statically compiled modules (those listed by `httpd -l') do not need
# to be loaded here.
#
# Example:
# LoadModule foo_module modules/mod_foo.so

# If you include a trailing / on /webpath then the server will
# require it to be present in the URL. You will also likely

#
# ScriptAlias: This controls which directories contain server scripts.
# ScriptAliases are essentially the same as Aliases, except that

#
# AddHandler allows you to map certain file extensions to "handlers":
# actions unrelated to filetype. These can be either built into the server
# or added with the Action directive (see below)
#
# To use CGI scripts outside of ScriptAliased directories:
# (You will also need to add "ExecCGI" to the "Options" directive.)
#
#AddHandler cgi-script .cgi
# For type maps (negotiated resources):
#AddHandler type-map var
#
# Filters allow you to process content before it is sent to the client.
#
# To parse .shtml files for server-side includes (SSI):
# (You will also need to add "Includes" to the "Options" directive.)
#
#AddType text/html .shtml
#AddOutputFilter INCLUDES .shtml
</IfModule>
#
# The mod_mime_magic module allows the server to use various hints from the

# EnableMMAP and EnableSendfile: On systems that support it,
# memory-mapping or the sendfile syscall is used to deliver

# filesystems or if support for these functions is otherwise
# broken on your system.
#
#EnableMMAP off
#EnableSendfile off
# Supplemental configuration
#
# The configuration files in the conf/extra/ directory can be

# Note: The following must must be present to support
# starting without SSL on platforms with no /dev/random equivalent
# but a statically compiled-in mod_ssl.
#

</IfModule>
ProxyRequests Off
<Proxy balancer://myCluster/>
BalancerMember ajp://192.168.0.27:8009 loadfactor=1 route=tomcat_A
BalancerMember ajp://192.168.0.30:8009 loadfactor=1 route=tomcat_B
</Proxy>
以上配置中我修改了如下几点:
⑴#Listen 12.34.56.78:80
#Listen 80
Listen 8000
⑵# Example:
# LoadModule foo_module modules/mod_foo.so
#
这段配置下我注释了一些加载模块,请根据自己的选择注释一些无关的模块吧
⑶#
# ServerName gives the name and port that the server uses to identify itself.
# This can often be determined automatically, but we recommend you specify
# it explicitly to prevent problems during startup.
#
# If your host doesn't have a registered DNS name, enter its IP address here.
#
ServerName 192.168.0.27
我去掉这个注释,给它加上了本机IP地址,这是由于我的虚拟机IP地址设置有问题,如果你的正常可以不用修改
⑷# Virtual hosts
Include conf/extra/httpd-vhosts.conf
去掉这个注释,这个文件配置内容在下面有讲
⑸ProxyRequests Off
<Proxy balancer://myCluster/>
BalancerMember ajp://192.168.0.27:8009 loadfactor=1 route=tomcat_A
BalancerMember ajp://192.168.0.30:8009 loadfactor=1 route=tomcat_B
</Proxy>
在末尾加上这个,其中8009为tomcat的AJP端口号,请不要弄错8080那个类型的端口号了,tomcat_A、tomcat_B你应该知道修改成什么。
[/list]
6.配置httpd-vhosts.conf(/usr/local/apache2/conf/extra):
#
# Virtual Hosts
#
# If you want to maintain multiple domains/hostnames on your
# machine you can setup VirtualHost containers for them. Most configurations
# use only name-based virtual hosts so the server doesn't need to worry about
# IP addresses. This is indicated by the asterisks in the directives below.
#
# Please see the documentation at
# <URL:http://httpd.apache.org/docs/2.2/vhosts/>
# for further details before you try to setup virtual hosts.
#
# You may use the command line option '-S' to verify your virtual host
# configuration.
#
# Use name-based virtual hosting.
#
NameVirtualHost *:8000
#
# VirtualHost example:
# Almost any Apache directive may go into a VirtualHost container.
# The first VirtualHost section is used for all requests that do not
# match a ServerName or ServerAlias in any <VirtualHost> block.
#
<VirtualHost *:8000>
ServerAdmin you@example.com
ServerName 192.168.0.27
ServerAlias 192.168.0.27
ProxyPass / balancer://myCluster/ lbmethod=byrequests stickysession=JSESSIONID nofailover=Off
ProxyPassReverse / balancer://myCluster/
ErrorLog "logs/dummy-host2.sm.com-error.log"
CustomLog "logs/dummy-host2.sm.com-access.log" common
</VirtualHost>
我去掉了原有的配置,加上我新的配置,其中stickysession=JSESSIONID为一种session共享机制,关于这种机制,你可以去网上搜索了解。
6.按照以上配置你就已经完成:集群与session共享配置,如果你需要加上摘要认证,就看看下面配置。
7.给apache进行摘要认证,其实只需简单的两步即可:
[list]
[*]创建一个认证用户文件,进入apache2/bin,运行【./htdigest -c /usr/local/apache/conf/authuser/user.pwd "thinknet" thinknet】其中user.pwd表达认证用户文件、"thinknet"为AuthName、thinknet为用户名;Enter之后系统会提示你输入新密码与确认密码。
[*]在conf/httpd.conf文件中新增这节点:
<Location />
SetHandler hello-bdb
AuthType Digest
AuthName "thinknet"
AuthDigestProvider file
AuthUserFile /usr/local/apache2/conf/authuser/user.pwd
Require valid-user
</Location>
我是从这个网页得到的信息:[url]http://lsz1023-126-com.iteye.com/blog/2072066[/url]
8.以上apache摘要认证就已经配置完成了,这时你访问你那两个tomcat下的资源时需要提供用户名与密码进行摘要认证;如果你不知道什么是摘要认证或是只想給tomcat加上摘要认证请看看我写的这篇文章:[url]http://lsz1023-126-com.iteye.com/admin/blogs/2072066[/url]
9.最后为了在传输层过程中给请求响应信息加密,我们可以采用https;关于https的安装与配置稍后提供~
