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

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[url=http://tomcat.apache.org/connectors-doc/miscellaneous/changelog.html]Changelog網頁[/url]
[quote]Add IPV6 support for connection to webserver. New directive prefer_ipv6 has been added to control the hostname resolution and preserve backward compatibility. (mturk)[/quote]
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
[code]worker.worker1.host=localhost
worker.worker2.host=localhost[/code]
改為127.0.0.1
[code]worker.worker1.host=127.0.0.1
worker.worker2.host=127.0.0.1[/code]
再重啟一次Apache，就可以順利連到Tomcat了。

[Tomcat]Deploy war檔時，讓每個context都有各自的AccessLogValve

jhliang — GMT

當您想要使用tomcat的AccessLogValve讓每個context都有各自的accesslog時，
方法很簡單，在您的war專案內，新增一個 /META-INF/context.xml 檔，編輯內容如下 :
[code]

......

prefix="MyWeb_access_log." suffix=".log" pattern="common" resolveHosts="false"/>

[/code]
當您將war檔deploy之後，Tomcat會自動幫您產生一個檔案 : {tomcat_home}/conf/Catalina/localhost/MyWeb.xml
然後在您的{tomcat_home}/logs/ 目錄下應該就可以看到您的MyWeb_access_log.xxxx.txt 檔了。

回覆:Linux環境下Tomcat catalina.out的管理

andowson — GMT

第二天:
如果順利切換過去，接下來就是將先前/etc/logrotate.d/tomcat中mark掉的mail developer等設定恢復。

再來可能會遇到的問題就是，昨天logrotate後，那個20幾GB的catalina.out現在只是檔名尾巴加上日期，大小還是20幾GB大。如果我們希望也能夠將它切一切，也一樣照日期分成一個一個檔，那應該如何處理呢?

由於沒有現成的工具程式(或是我不知道有這種工具)可以處理catalina.out-20120801，於是我先土法煉鋼來處理這個切檔的工作:
先用vi開啟這個檔案(是的，20幾GB)，然後找到昨天的日期第一次出現在這個檔案的行數，再找出檔案尾巴的行數，將這個區塊寫到另一個檔案去，例如catalina.out-20120731，再將原先的catalina.out-20120801檔案刪掉該區塊的內容。這樣子重複執行直到將檔案全部切好為止。

我手動切了三個日期後，就覺得這樣子下去不是辦法，應該可以寫個shell script來處理這件事:
1.使用grep -n指令搭配head -1來找出某個日期第一次出現在檔案中的行號:
grep -n "2012/7/31" catalina.out-20120801|head -1|awk '{print $1}'|cut -d":" -f1
2.然後利用wc -l 來找出檔案尾巴行數:
wc -l catalina.out-20120801|awk '{print $1}'
3.接下來利用expr將兩個行號相減再加一:
expr $end - $start + 1
4.再利用tail 指令搭配行數，將自檔尾倒數幾行寫到檔案catalina.out-20120731去
tail -$lines catalina.out-20120801 > catalina.out-20120731
5.最後再利用sed指令去刪掉剛剛自起始行號到結尾行號中間的檔案內容
sed -i -e "${start},${end}d" catalina.out-20120801

搭配一下日期年月日的迴圈後可以組成如下:
split_catalina_out.sh:
[code]#!/bin/bash
file=catalina.out-20120801
for y in {2012..2011}
do
for m in {12..1}
do
for d in {31..1}
do
target="$y/$m/$d"
target_ym="${y}${m}"
if [ $m -lt 10 ]; then
target_ym="${y}0${m}"
fi
target_date="${target_ym}${d}"
if [ $d -lt 10 ]; then
target_date="${target_ym}0${d}"
fi

start=`grep -n $target $file|head -1|awk '{print $1}'|cut -d":" -f1`
if [ "$start" == "" ]; then
continue
fi
end=`wc -l $file|awk '{print $1}'`
lines=`expr $end - $start + 1`
echo $target_date
tail -$lines $file > ./catalina.out-$target_date
sed -i -e "${start},${end}d" $file
done
done
done[/code]

建議先複製一份catalina.out-20120801到/tmp目錄，測試看看，以免毀了原始紀錄檔。將split_catalina_out.sh放在和catalina.out-20120801相同的目錄下，執行時程式會自動判斷該日期是否存在於檔案中，如不存在將自動跳過。如此不斷重複直到回圈執行完畢。

回覆:如何限制只有某些IP才能使用Tomcat Manager

andowson — GMT

Tomcat 7.0的設定方法:
將webapps/host-manager/manager.xml 複製到conf/Catalina/localhost下

在manager.xml中加入下列設定到Context
[code] allow="127\.0\.0\.1|114\.\d+\.\d+\.\d+" denyStatus="404" />[/code]
兩個以上的IP用"|"分隔，注意到.前面要加上倒斜線(\)。
如:
[code] privileged="true" antiResourceLocking="false" antiJARLocking="false">
allow="127\.0\.0\.1|114\.\d+\.\d+\.\d+" denyStatus="404" />
[/code]

實際測試，發現不需重啟Tomcat立即生效

在 CentOS 5 上安裝 WebLogic Server 10.0 MP1

andowson — GMT

在 CentOS 5 上安裝 WebLogic Server 10.0 MP1

設計理念:
1.需要啟動兩個WebLogic Server，一個是AdminServer，一個是ManagedServer。AdminServer負責管理Project Domain，ManagedServer負責執行被佈署上去的WebApp。
2.因為該主機上尚需執行其他AP Server(如Tomcat)，我們讓ManagedServer跑在Port 8081上，並透過proxy機制整合至Apache以免佔用port 80。

實作步驟:
1.安裝JDK 5.0
:!: WebLogic Server 10.0 MP1必須搭配JDK 5.0版本使用，如果改用JDK 6.0，雖然可以執行，但將會在log檔中看到一堆錯誤訊息，且運作起來會有很多不順的現象。如果系統上已經安裝JDK 6.0者須先反安裝，待安裝完JDK 5.0後再裝回JDK 6.0。
:arrow: 下載Sun Java Development Kit 5.0 Update 22(JDK 5.0在2009/11/3被宣告EOSL，最後的公眾可下載版本是Update 22，如果有購買Java SE for Business者可下載較新版本)
x86_64:
[code=bash]cd /tmp
wget http://download.oracle.com/otn-pub/java/jdk/1.5.0_22/jdk-1_5_0_22-linux-amd64-rpm.bin -O jdk-1_5_0_22-linux-amd64-rpm.bin[/code]
x86:
[code=bash]cd /tmp
wget http://download.oracle.com/otn-pub/java/jdk/1.5.0_22/jdk-1_5_0_22-linux-i586-rpm.bin -O jdk-1_5_0_22-linux-i586-rpm.bin[/code]
:arrow: 安裝JDK 5.0 Update 22
[code=bash]sh jdk-1_5_0_22-linux-amd64-rpm.bin[/code]
:idea: 安裝路徑:/usr/java/jdk1.5.0_22

2.安裝WebLogic Server
:arrow: 上傳光碟檔案B46881-01.zip至/tmp目錄下
:arrow: 解壓縮
[code=bash]cd /tmp
unzip B46881-01.zip
[/code]
:arrow: 開始安裝
[code=bash]java -jar server1001_generic.jar[/code]

BEA_HOME=/var/bea
選擇自訂安裝，取消安裝Server Examples [1.2]及Workshop for WebLogic Platform [2]

3.建立WebLogic Domain
[code=bash]cd /var/bea/wlserver_10.0/common/bin
./config.sh
[/code]
設定weblogic的密碼
設定啟動模式: Development Mode
選擇JDK的路徑:/usr/java/jdk1.5.0_22

4.上傳啟動用的shell script至/var/bea/user_projects/domains/base_domain/
:arrow: 先將原本產生的startWebLogic.sh更名
[code=bash]cd /var/bea/user_projects/domains/base_domain/
mv startWebLogic.sh startWebLogic.sh.orig
chmod a-x startWebLogic.sh.orig
[/code]
:arrow: 上傳下列檔案
startAdminServer.sh
startManagedServer.sh
startOnBoot.sh
startWebLogic.sh
stopAdminServer.sh
stopManagedServer.sh
:arrow: 編輯下列檔案，取代AdminServer的IP
startManagedServer.sh
stopManagedServer.sh
:arrow: 將檔案設定為可執行
[code=bash]
cd /var/bea/user_projects/domains/base_domain/
chmod a+x *.sh
[/code]

5.建立boot.properties符號連結
[code=bash]cd /var/bea/user_projects/domains/base_domain/
ln -s servers/AdminServer/security/boot.properties boot.properties
[/code]

6.建立Log目錄
[code=bash]mkdir -p /var/log/bea[/code]

7.啟動AdminServer
[code=bash]cd /var/bea/user_projects/domains/base_domain/
./startAdminServer.sh[/code]

8.開放防火牆iptables
加上下列port
7001:tcp

9.登入weblogic console
:arrow: 開啟瀏覽器，輸入下列網址
http://my_server_ip:7001/console/
帳號跟密碼就是步驟3.建立WebLogic Domain時所輸入的資訊
:arrow: 建立一個新的Server:
Name: ManagedServer
Listen Port: 8081

10.啟動ManagedServer
[code=bash]cd /var/bea/user_projects/domains/base_domain/
./startManagedServer.sh[/code]

11.檢查ManagedServer的狀態是否為RUNNING

12.關閉ManagedServer:
[code=bash]cd /var/bea/user_projects/domains/base_domain/
./stopManagedServer.sh[/code]

13.關閉AdminServer:
[code=bash]cd /var/bea/user_projects/domains/base_domain/
./stopAdminServer.sh[/code]

到此完成WebLogic Server 10.0 MP1的安裝

接下來再透過WebLogic Server的Apache HTTP Server Plug-In整合至Apache HTTP Server 2.2
x86_64:
[code=bash]cp -p /var/bea/wlserver_10.0/server/plugin/linux/x86_64/mod_wl_22.so /etc/httpd/modules/.[/code]
x86:
[code=bash]cp -p /var/bea/wlserver_10.0/server/plugin/linux/i686/mod_wl_22.so /etc/httpd/modules/.[/code]
vi /etc/httpd/conf.d/mod_wl.conf
[code=text]LoadModule weblogic_module modules/mod_wl_22.so

WebLogicHost localhost
WebLogicPort 8081
MatchExpression *.jsp

SetHandler weblogic-handler
[/code]

:arrow: 測試一下設定有沒有問題:
[code=bash]httpd -t[/code]
如果出現Syntax OK就表示沒問題了

:arrow: 重新啟動WebLogic Server和Apache Server
[code=bash]cd /var/bea/user_projects/domains/base_domain/
./startOnBoot.sh
/etc/init.d/httpd restart[/code]
就可以透過下面的網址來存取myapp了
http://my_server_ip/myapp

# intranet workaround
# If your server doesn't have direct access to the Internet, ie. in the company
# intranet behind a firewall, you can modify your server's proxy setting by edit
# /etc/wgetrc:
#http_proxy = http://proxy.yourcompany.com:8080/
#use_proxy = on

# If you still can't use proxy then you have to download all the files manually.
# After download, copy them into ${SETUP_DIR}. And then change the following

Cluster Session Replication Test

String key = request.getParameter("key");
if (key != null && key.length() > 0) {
String value = request.getParameter("value");

[/code]

4.Then you can use the following two commands to do step12
service tomcat start
service httpd start
5. For testing, you can use the following command to shutdown or startup a single Tomcat worker:
su -l tomcat -c "export CATALINA_BASE=/var/robust/worker1; /var/tomcat7/bin/shutdown.sh"
su -l tomcat -c "export CATALINA_BASE=/var/robust/worker1; /var/tomcat7/bin/startup.sh"
su -l tomcat -c "export CATALINA_BASE=/var/robust/worker2; /var/tomcat7/bin/shutdown.sh"
su -l tomcat -c "export CATALINA_BASE=/var/robust/worker2; /var/tomcat7/bin/startup.sh"

Or you may use a shell script to restart Tomcat repeatedly to verify if the session replication really works.
[b]restart.sh[/b]
[code]
for (( i = 0 ; i < 10 ; i++ ))
do
service tomcat restart
done
[/code]

If you can see all of the session objects no matter how Tomcat is restarted, then Tomcat clustering(session replication) is done.

Note: If you have enabled firewall like iptables, please add http(80:tcp), https(443:tcp) and [color=red]45564:udp[/color] port to the allowed list.

6. Finally, browse https:/// to check SSL works. You have to add this site as your trust site because we use a self-signed SSL certificate.

解決wget 檢查https連線時出現Certificate verification error: self signed certificate in certificate chain

andowson — GMT

原本使用wget https://eip.mycomp.com 會出現錯誤訊息，將Apache所在主機(eip.mycomp.com)之/etc/httpd/conf/ssl.crt/ca.crt複製到wget所在主機後，改用下列方式連線即可:
wget --ca-certificate /path/to/ca.crt https://eip.mycomp.com

強制將http導到https

andowson — GMT

最近公司資安議題發燒，為了加強安全性，我們決定將整個網站都透過https傳輸方式讓使用者使用，而要達成這個自動強制將http導到https只要透過Apache的[url=http://httpd.apache.org/docs/current/mod/mod_rewrite.html]mod_rewrite[/url]機制，很輕鬆就可以達成，如下，在/etc/httpd/conf/httpd.conf內加入如下設定即可:

[code]RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}[/code]

然後重啟Apache
[code]/etc/init.d/httpd restart[/code]

[注意]如果您是看畫面自己打字輸入的人，要特別小心(這個小細節花了我好多時間才注意到):
1.%{HTTP_HOST}和%{REQUEST_URI}中間沒有斜線('/')
2.%{HTTP_HOST}和%{REQUEST_URI}是%開頭，不是$開頭

解決WebLogic Server無法啟動問題： Unable to start WebLogic Server!! WebLogic: license error, Invalid host IP

andowson — GMT

昨天幫主機啟動第二張網卡，設定了另一個IP，並修改了一下/etc/hosts，結果今天早上就收到一封信：

[quote]$$$$$$$$$$$$$$$$ License Exception $$$$$$$$$$$$$$$$

Unable to start WebLogic Server!!
WebLogic: license error, Invalid host IP

$$$$$$$$$$$$$$$$ License Exception $$$$$$$$$$$$$$$$[/quote]

把第二張網卡停用也無法重新啟動WebLogic Server，甚至把/etc/hosts回復成原來的樣子也起動不了。 :XD:
後來上網搜尋了一下，找到這篇：[url]http://www.buildanddeploy.com/node/5[/url]，發現把主機IP移到/etc/hosts第一行，再重起WebLogic Server就成功了。
