今天將Tomcat Connector利用自動更新程式tomcat-connector.sh(如下)進行更新:

#!/bin/bash

# Name: Apache 2.2.x && Tomcat 7.0.x auto installer for CentOS 6.x

# Author: Andowson Chang (andowson [at] gmail [dot] com)

# Version: 5.16

# Last Modified: 2014-04-20

# Source: http://www.andowson.com

#

TOMCAT_CONNECTOR_VERSION=1.2.40



MIRROR_HOST=apache.stu.edu.tw

SETUP_DIR=/root/setup/web

INTERNET_CONNECTED=1



# 

# install dependency packages

#

LIBTOOL_INSTALLED=`rpm -qa|grep libtool|wc -l`

HTTPD_DEVEL_INSTALLED=`rpm -qa|grep httpd-devel|wc -l`

AUTOMAKE_INSTALLED=`rpm -qa|grep automake|wc -l`

if [ ${LIBTOOL_INSTALLED} = 0 ] || [ ${HTTPD_DEVEL_INSTALLED} = 0 ] || [ ${AUTOMAKE_INSTALLED} = 0 ]; then

   yum -y install libtool httpd-devel automake

fi



#

# create the setup directory

#

if [ ! -d ${SETUP_DIR} ]; then

   mkdir -p ${SETUP_DIR}

fi

cd ${SETUP_DIR}



#

# get latest version

#

wget http://tomcat.apache.org/download-connectors.cgi -q -t 1 -T 5 -O /tmp/connector.html

if [ -s /tmp/connector.html ]; then

   TOMCAT_CONNECTOR_VERSION=`grep "1\.2\." /tmp/connector.html|cut -d">" -f2|cut -d"<" -f1 |awk '{print $2}'|grep "1.2"|uniq`

else

   echo "Cannot connect to the Internet. Try using local file instead."

   INTERNET_CONNECTED=0

fi

rm -rf /tmp/connector.html

if [ ! -r tomcat-connectors-${TOMCAT_CONNECTOR_VERSION}-src.tar.gz ]; then

   if [ $INTERNET_CONNECTED -eq 1 ]; then

      wget http://${MIRROR_HOST}/tomcat/tomcat-connectors/jk/tomcat-connectors-${TOMCAT_CONNECTOR_VERSION}-src.tar.gz

   else

      echo "File not found: tomcat-connectors-${TOMCAT_CONNECTOR_VERSION}-src.tar.gz, aborted!"

      exit 1

   fi

fi



#

# install tomcat connector

#

echo "Install Tomcat Connector JK ${TOMCAT_CONNECTOR_VERSION}"

tar zxvf tomcat-connectors-${TOMCAT_CONNECTOR_VERSION}-src.tar.gz

cd tomcat-connectors-${TOMCAT_CONNECTOR_VERSION}-src/native

./buildconf.sh

./configure --with-apxs=/usr/sbin/apxs

make

make install

cd ${SETUP_DIR}

完成更新後，重啟Apache，再去開網頁卻無法順利開啟網頁，查了一下mod_jk.log:

[Sun Apr 20 13:30:34 2014][15480:139841517975520] [info] init_jk::mod_jk.c (3383): mod_jk/1.2.40 initialized

[Sun Apr 20 13:30:39 2014][15492:139841517975520] [error] ajp_send_request::jk_ajp_common.c (1663): (worker1) connecting to backend failed. Tomcat is probably not started or is listening on the wrong port (errno=111)

[Sun Apr 20 13:30:39 2014][15492:139841517975520] [info] ajp_service::jk_ajp_common.c (2673): (worker1) sending request to tomcat failed (recoverable), because of error during request sending (attempt=1)

發現無法連到::1:8109(這是IPv6的locahost IP表示方法)
在查了一下Tomcat的Changelog網頁

Add IPV6 support for connection to webserver. New directive prefer_ipv6 has been added to control the hostname resolution and preserve backward compatibility. (mturk)

感覺應該是預設用IPv6在抓IP，由於我不知道怎麼調整這個預設模式，故我採用修改workers.properties
將這兩行設定的localhost

worker.worker1.host=localhost

worker.worker2.host=localhost

改為127.0.0.1

worker.worker1.host=127.0.0.1

worker.worker2.host=127.0.0.1

再重啟一次Apache，就可以順利連到Tomcat了。
