1. 安裝Tomcat

1.1. install java

解壓安裝

chmod +x jdk-6u1-linux-i586.bin
./jdk-6u1-linux-i586.bin
輸入"yes"回車

mv jdk1.6.0_01 /usr/local/
ln -s /usr/local/jdk1.6.0_01/ /usr/local/java

/etc/profile.d/java.sh

例 4.1. /etc/profile.d/java.sh

################################################
### Java environment
################################################
export JAVA_HOME=/usr/local/java
export JRE_HOME=/usr/local/java/jre
export PATH=$PATH:/usr/local/java/bin:/usr/local/java/jre/bin
export CLASSPATH="./:/usr/local/java/lib:/usr/local/java/jre/lib:/usr/local/memcached/api/java"
export JAVA_OPTS="-Xms512m -Xmx1024m"

1.2. install tomcat

下載binary解壓到/usr/local/

下載軟件包

wget http://archive.apache.org/dist/tomcat/tomcat-6/v6.0.13/bin/apache-tomcat-6.0.13.tar.gz
wget http://archive.apache.org/dist/tomcat/tomcat-connectors/native/tomcat-native-1.1.10-src.tar.gz
wget http://archive.apache.org/dist/tomcat/tomcat-connectors/jk/source/jk-1.2.23/tomcat-connectors-1.2.23-src.tar.gz

tar zxvf apache-tomcat-6.0.13.tar.gz
mv apache-tomcat-6.0.13 /usr/local/
ln -s /usr/local/apache-tomcat-6.0.13/ /usr/local/tomcat

tomcat-native

tar zxvf tomcat-native-1.1.10-src.tar.gz
cd tomcat-native-1.1.10-src/jni/native
./configure --with-apr=/usr/local/apache/bin/apr-1-config --with-java-home=/usr/local/java/
make
make install

catalina.sh

CATALINA_OPTS="-Djava.library.path=/usr/local/apr/lib"
JAVA_OPTS="-Xss128k -Xms128m -Xmx1024m -XX:PermSize=128M -XX:MaxPermSize=256m -XX:MaxNewSize=256m"

啟動

startup.sh

1.2.1. tomcat-native

			
cd /usr/local/tomcat-6.0.18/bin
tar zxvf tomcat-native.tar.gz
cd tomcat-native-1.1.14-src/jni/native
./configure --with-apr=/usr/local/apr --with-java-home=/usr/java/jdk1.6.0_11
make && make install

1.3. 同時運行多實例

創建工作目錄

mkdir /srv/apache-tomcat

每個連接埠一個目錄

tar zxvf apache-tomcat-7.0.x.tar.gz
mv  apache-tomcat-7.0.x /srv/apache-tomcat/8080

tar zxvf apache-tomcat-7.0.x.tar.gz
mv  apache-tomcat-7.0.x /srv/apache-tomcat/9090

		

<Server port="8006" shutdown="SHUTDOWN">


 <Connector port="9090" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

<!--
    <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
-->

1.4. Connector

1.4.1. server.xml

vi conf/server.xml

			
    <Connector port="8009"
                maxThreads="4096"
                minSpareThreads="100"
                maxSpareThreads="500"
                enableLookups="false"
                acceptCount="15000"
                connectionTimeout="30000"
                redirectPort="8443"
                disableUploadTimeout="true"
                URIEncoding="UTF-8"
                protocol="AJP/1.3"/>

1.4.2. mod_jk

mod_jk 安裝

tar zxvf tomcat-connectors-1.2.23-src.tar.gz
cd tomcat-connectors-1.2.23-src/native/
./configure --with-apxs=/usr/local/apache/bin/apxs
make
make install
chmod 755 /usr/local/apache/modules/mod_jk.so

httpd.conf 尾部加入

Include conf/mod_jk.conf

配置workers.properties

apache/conf/workers.properties

# Define 1 real worker using ajp13
worker.list=worker1
# Set properties for worker1 (ajp13)
worker.worker1.type=ajp13
worker.worker1.host=127.0.0.1
worker.worker1.port=8009
worker.worker1.lbfactor=1
worker.worker1.cachesize=128
worker.worker1.cache_timeout=600
worker.worker1.socket_keepalive=1
worker.worker1.reclycle_timeout=300

mod_jk.conf

apache/conf/mod_jk.conf

		
[chenjingfeng@d3010 Includes]$ cat mod_jk.conf
<IfModule mod_jk.c>
# Load mod_jk module
LoadModule jk_module            modules/mod_jk.so
# Where to find workers.properties
JkWorkersFile           /usr/local/apache/conf/workers.properties
# Where to put jk logs
JkLogFile               /usr/local/apache/logs/mod_jk.log
# Set the jk log level [debug/error/info]
JkLogLevel              error
# 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"
JkShmFile     /usr/local/apache2/logs/mod_jk.shm
# Send jsp,servlet for context * to worker named worker1
JkMount  /status/* worker1
JkMount  /*.jsp worker1
JkMount  /*.jsps worker1
JkMount  /*.do worker1
JkMount  /*Servlet worker1
JkMount  /jk/* worker1
</IfModule>

分別測試apache,tomcat

1.4.3. mod_proxy_ajp

包含虛擬主機配置檔案

# vi conf/httpd.conf

# Virtual hosts
Include conf/extra/httpd-vhosts.conf

虛擬主機中配置ProxyPass,ProxyPassReverse

# vi conf/extra/httpd-vhosts.conf

		
<VirtualHost *:80>
    ServerName netkiller.8800.org
    ProxyPass /images !
	ProxyPass /css !
	ProxyPass /js !
    ProxyPass /ajp ajp://localhost:8009/ajp
    ProxyPassReverse /ajp ajp://localhost:8009/ajp
</VirtualHost>

反向代理和均衡負載模組

		
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
LoadModule proxy_balancer_module modules/mod_proxy_balancer.so

ProxyPass /admin balancer://tomcatcluster/admin lbmethod=byrequests stickysession=JSESSIONID nofailover=Off timeout=5 maxattempts=3
ProxyPassReverse /admin balancer://tomcatcluster/admin

<Proxy balancer://tomcatcluster>
	BalancerMember ajp://localhost:8009 route=web1
	BalancerMember ajp://localhost:10009 smax=10 route=web2
	BalancerMember ajp://localhost:11009 route=web3
	BalancerMember ajp://localhost:12009 smax=10 route=web4
</Proxy>

1.4.4. RewriteEngine 連接 Tomcat

		
RewriteEngine On

RewriteRule ^/(.*) ajp://localhost:8009/ajp/$1 [P]
RewriteRule ^/(.*\.(jsp|do|sevlet)) ajp://localhost:8009/ajp/$1 [P]

1.5. Testing file

測試目錄

[root@backup tomcat]# mkdir webapps/ajp
[root@backup tomcat]# mkdir webapps/jk
[root@backup tomcat]# vi webapps/ajp/index.jsp
[root@backup tomcat]# vi webapps/jk/index.jsp

測試檔案
