httpd,mod_jk,tomcat,loadbalance

1. 环境配置以及安装指南

Apache：httpd-2.2.21

Mod_jk: tomcat-connectors-1.2.32-src.tar.gz

Tomcat: apache-tomcat-7.0.23.tar.gz

版本说明信息; http://tomcat.apache.org/connectors-doc/webserver_howto/apache.html

1.1 安装apache

A:解压apache

tar -zxvf httpd-2.2.21-beta.tar.gz

cd httpd-2.3.16-beta

B:配置

./configure --prefix=/ceno/product/httpd --enable-module=vhost_alias --enable-module=so

Make

Make install

C:提示缺少apr以及aprutil,pcre,则需要先编译apr,aprutil以及pcre.

C1:下载apr,aprutil 以及 pcre

apr: http://apr.apache.org/download.cgi
apr-util: http://apr.apache.org/download.cgi
pcre: http://pcre.org/、 http://sourceforge.net/projects/pcre/

c2:安装apr:

tar zxvf apr-1.4.5.tar.gz

cd apr-1.4.5

./configure --prefix=/usr/local/apr

Make

make install

c3:安装aprtuil

tar zxvf apr-util-1.3.10.tar.gz

cd apr-util-1.3.10

./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr

Make

make install

c4安装pcre

tar zxvf pcre-8.11.tar.gz

cd pcre-8.11

./configure --prefix=/usr/local/pcre

Make

make install

D：重新编译httpd

cd httpd-2.2.21

./configure --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --with-pcre=/usr/local/pcre --prefix=/ceno/product/httpd --enable-module=vhost_alias --enable-module=so

Make

Make install

1.2 安装并编译mod_jk

Tar –zxvf tomcat-connectors-1.2.32-src.tar.gz

Cd tomcat-connectors-1.2.32-src/native

./configure --with-apxs=/ceno/product/httpd/bin/apxs

Make

Su –c ‘make install’

1.3 解压tomcat7.0

Tar –zxvf apache-tomcat-7.0.23.tar.gz

Cd /ceno/product/

Ln –s /work/apache/ apache-tomcat-7.0.23 tomcat

2. 配置篇章

2.1 配置httpd.conf

Cd /ceno/product/httpd/conf

Vi httpd.conf

下面是

# 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 www.example.com:80

ServerName 192.168.7.18:80

# DocumentRoot: The directory out of which you will serve your

# documents. By default, all requests are taken from this directory, but

# symbolic links and aliases may be used to point to other locations.

#DocumentRoot "/ceno/product/httpd/htdocs"

DocumentRoot "/ceno/product/tomcat/webapps/examples"

# Possible values for the Options directive are "None", "All",

# or any combination of:

# Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews

# Note that "MultiViews" must be named *explicitly* --- "Options All"

# doesn't give it to you.

# The Options directive is both complicated and important. Please see

# http://httpd.apache.org/docs/2.2/mod/core.html#options

# for more information.

Options Indexes FollowSymLinks

# AllowOverride controls what directives may be placed in .htaccess files.

# It can be "All", "None", or any combination of the keywords:

# Options FileInfo AuthConfig Limit

AllowOverride None

# Controls who can get stuff from this server.

Order allow,deny

Allow from all

</Directory>

#加入mod_jk配置

Include conf/jk/mod_jk.conf

2.2 在httpd/conf 下添加jk目录，配置mod_jk.conf

Cd /ceno/product/httpd/conf/jk/

#load mod_jk module

LoadModule jk_module modules/mod_jk.so

# Declare the module for <IfModule directive> (remove this line on Apache 2.0.x)

#AddModule mod_jk.c

# Where to find workers.properties

JkWorkersFile /ceno/product/httpd/conf/jk/workers.properties

# Where to put jk shared memory

JkShmFile /ceno/product/httpd/mod_jk.shm

# Where to put jk logs

JkLogFile /ceno/product/httpd/logs/mod_jk.log

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

JkLogLevel debug

# Select the timestamp 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"

# Static files in all Tomcat webapp context directories are served by apache

JkAutoAlias /ceno/product/tomcat/webapps/examples

# All requests go to worker1 by default

JkMount /* balance1

# Serve html, jpg and gif using httpd

JkUnMount /*.html balance1

JkUnMount /*.jpg balance1

JkUnMount /*.gif balance1

# Add the jkstatus mount point

JkMount /jkmanager/* jkstatus

workers.properties

# the list of workers

worker.list= worker1,worker2,balance1,jkstatus

##worker.worker name.type=<worker type> Where worker name is the name assigned to the worker and the worker type is one of the four types defined in the table

##(a worker name may only contain any space the characters [a-zA-Z0-9\-_]).

##Type Description

#ajp12 This worker knows how to forward requests to out-of-process Tomcat workers using the ajpv12 protocol.

#ajp13 This worker knows how to forward requests to out-of-process Tomcat workers using the ajpv13 protocol.

#jni DEPRECATED: This worker knows how to forward requests to in-process Tomcat workers using JNI.

#lb This is a load-balancing worker; it knows how to provide round-robin based sticky load balancing with a certain level of fault-tolerance.

#Defines a worker named "loadbalancer" that loadbalances several Tomcat processes transparently.

# Set properties for worker1 (ajp13)

worker.worker1.type=ajp13

worker.worker1.host=192.168.7.18

worker.worker1.port=8009

worker.worker1.lbfactor=1

# Set properties for worker2 (ajp13)

worker.worker2.type=ajp13

worker.worker2.host=192.168.7.18

worker.worker2.port=8010

worker.worker2.lbfactor=3

#worker.worker2.connection_pool_timeout=600

#worker.worker2.socket_keepalive=1

#worker.worker2.socket_timeout=60

worker. balance1.type=lb

#After defining the workers you can also specify properties for them. Properties can be specified in the following manner:

#worker.<worker name>.<property>=<property value>

# The worker balance1 while use "real" workers worker1 and worker2

worker.balance1.balance_workers=worker1, worker2

worker.balance1.sticky_session =true

# Define a 'jkstatus' worker using status

worker.jkstatus.type=status

2.3 配置tomcat

一台机器上测试 2个tomcat：

Tomcat1:

<Connector port="8080" protocol="HTTP/1.1"

connectionTimeout="20000"

redirectPort="8443" />

Tomcat2:

<Connector port="8081" protocol="HTTP/1.1"

connectionTimeout="20000"

redirectPort="8445" />

一个tomcat 两个实例

修改/tomcat/conf/server.xml 文件，添加一个service

<?xml version='1.0' encoding='utf-8'?>

2.4 配置Jk status

方法一：

在worker.peroerties 文件中增加：

worker.list=worker1,worker2,balancer1,jkstatus

# Define a 'jkstatus' worker using status

worker.jkstatus.type=status

在mod_jk.conf 中增加

# Add the jkstatus mount point

JkMount /jkmanager/* jkstatus

打开浏览器访问：

http://192.168.7.18/jkmanager

方法二：

在workers.properties 文件中添加

worker.list=worker1,worker2,balancer1,jkstatus

# Define a 'jkstatus' worker using status

worker.jkstatus.type=status

worker. jkstatus.read_only=true

worker.jkstatus.mount=/admin/status/jk

worker. jkstatus.read_only 属性默认为false

打开浏览器访问

http://192.168.7.18/admin/status/jk
