How to Install Atlassian Jira 5.0.6 on Ubuntu 12.04

Abstract

JIRA is the project tracker for teams building great software. JIRA sits at the center of your development team, connecting the people and the work being done. Track bugs and tasks, link issues to related source code, plan agile development, monitor activity, report on project status, and more. This blog entry will guide you through the process of installing JIRA on Ubuntu.

Introduction

This installation guide is divided into 4 stages. During the first stage, you will install the Oracle JDK 6 update 32 platform. During the second stage, you will install the Apache Tomcat 6.0.35 application server. During the third stage, you will install the PostgreSQL 9.1 database server, and during the final stage, you will install Atlassian JIRA 5.0.6.

Disclaimer

This installation guide is intended for persons evaluating Atlassian JIRA and by no means represents a complete and production-ready configuration.

Before you begin

Tomcat 6.0.24 contains a critical bug. Please use 6.0.32 or later.
Deploying multiple Atlassian applications in a single Tomcat container is not supported.

Stage 4 Step 1: Download and extract the JIRA Archive

Run the following commands in your console window:
Change to your Home folder.

cd ~/

Download the JIRA WAR distribution using wget:

wget http://www.atlassian.com/software/jira/downloads/binary/atlassian-jira-5.0.6-war.tar.gz

Extract the compressed archive:

tar xvzf atlassian-jira-5.0.6-war.tar.gz

The extracted directory is hereafter referred to as your JIRA Installation Directory.

Step 2: Create a dedicated user to run JIRA

JIRA runs under the user it is invoked and therefore can potentially be abused. For this reason, create a dedicated user:

sudo /usr/sbin/useradd --create-home --comment "Account for running JIRA" --shell /bin/bash jira

Step 3: Confine the directories that the new JIRA user can write to

Assign the JIRA user and JIRA group to the JIRA Installation Directory:

sudo chown jira:jira -R atlassian-jira-5.0.6-war/

Assign read/write rights to the owner and group of the JIRA Installation Directory:

sudo chmod u+rwx -R atlassian-jira-5.0.6-war/

sudo chmod g+rwx -R atlassian-jira-5.0.6-war/

Add the tomcat6 user to the JIRA group:

sudo adduser tomcat6 jira

Step 4: Customizing files in your JIRA Installation Directory

Please ensure that you only edit files in the edit-webapp directory. If you need to edit files in the webapp directory, copy them from the webapp directory to the edit-webapp directory. Continue to the next step.

Step 5: Ensure that the Transaction Factory has been specified correctly

Edit the entityengine.xml file and ensure that it contains:

<transaction-factory class="org.ofbiz.core.entity.transaction.JNDIFactory">

<user-transaction-jndi jndi-server-name="default"

jndi-name="java:comp/env/UserTransaction">

<transaction-manager-jndi jndi-server-name="default"

jndi-name="java:comp/env/UserTransaction">

</transaction-factory>

Using this command in your console window:

nano atlassian-jira-5.0.6-war/edit-webapp/WEB-INF/classes/entityengine.xml

Step 6: Create the JIRA Home Directory

The JIRA Home Directory is created under the var directory. This is a well-known location in the Linux file system for storing files that can grow, such as application data or log files.
Atlassian also recommends that you create your JIRA Home Directory independently from your JIRA Installation Directory.
Run the following command in your console window to create the JIRA Home directory:

sudo mkdir -p /var/atlassian/application-data/jira

sudo chown jira:jira /var/atlassian/application-data/jira

sudo chmod u+rwx /var/atlassian/application-data/jira

sudo chmod g+rwx /var/atlassian/application-data/jira

Step 7: Configure JIRA with the location of the JIRA Home directory

Edit the jira-application.properties file by running the following command in your console window:

sudo nano atlassian-jira-5.0.6-war/edit-webapp/WEB-INF/classes/jira-application.properties

Now change the jira.home property to:

jira.home = /var/atlassian/application-data/jira

Step 8: Move the JIRA Installation Directory

Move the JIRA Installation Directory from your Home directory to the opt directory on the file system:

sudo mv ~/atlassian-jira-5.0.6-war/ /opt

cd /opt

Step 9: Build JIRA

We are now going to perform a build in the JIRA Installation Directory that will produce a deployable WAR file in the dist-tomcat/tomcat-6 subdirectory of the JIRA Installation Directory.
Navigation to your JIRA Installation Directory:

cd atlassian-jira-5.0.6-war/

Run the build script:

sudo ./build.sh

Step 10: Download the PostgreSQL JDBC driver

Tomcat requires an appropriate JDBC driver to allow JIRA to communicate with the PostgreSQL database. Although there are newer release drivers available, Atlassian recommends using the 8.4 version.
Navigate back to your Home directory:

cd ~/

Download the PostgreSQL 8.4 JDBC driver:

wget http://jdbc.postgresql.org/download/postgresql-8.4-703.jdbc4.jar

Step 11: Configure Tomcat with the PostgreSQL JDBC driver

Move the driver to the shared Java library directory:

sudo mv postgresql-8.4-703.jdbc4.jar /usr/share/java

Navigate to the Tomcat lib directory:

cd /usr/share/tomcat6/lib

Create a soft symbolic link to the driver:

sudo ln -sT ../../java/postgresql-8.4-703.jdbc4.jar postgresql-8.4-703.jdbc4.jar

Step 12: Configure other Tomcat libraries for JIRA

Tomcat does not come with some libraries required by JIRA. They are made available for download from the Altassian website in a zipped archive.
Navigate to your Home directory:

cd ~/

Download the zipped archive:

wget http://www.atlassian.com/software/jira/downloads/binary/jira-jars-tomcat-distribution-5.0-rc2-tomcat-6x.zip

Install the unzip package:

sudo apt-get install unzip

Unzip the archive:

unzip jira-jars-tomcat-distribution-5.0-rc2-tomcat-6x.zip

List the libraries in the shared Java directory and remove any versions of the libraries you just extracted from the zipped archive:

ls /usr/share/java/*.jar

Move the extracted libraries to the Java shared directory:
If they are the only jar files in your Home folder, you can move them with one command:

sudo mv *.jar /usr/share/java

If not, you can copy and paste the commands below one by one:

sudo mv slf4j-api-1.5.8.jar /usr/share/java

sudo mv slf4j-log4j12-1.5.8.jar /usr/share/java

sudo mv jul-to-slf4j-1.5.8.jar /usr/share/java

sudo mv jcl-over-slf4j-1.5.8.jar /usr/share/java

sudo mv log4j-1.2.16.jar /usr/share/java

sudo mv hsqldb-1.8.0.5.jar /usr/share/java

sudo mv jta-1.0.1B.jar /usr/share/java

sudo mv ots-jts-1.0.jar /usr/share/java

sudo mv jotm-1.4.3.jar /usr/share/java

sudo mv jotm-jrmp_stubs-1.4.3.jar /usr/share/java

sudo mv jotm-iiop_stubs-1.4.3.jar /usr/share/java

sudo mv jonas_timer-1.4.3.jar /usr/share/java

sudo mv objectweb-datasource-1.4.3.jar /usr/share/java

sudo mv carol-1.5.2.jar /usr/share/java

sudo mv carol-properties-1.5.2.jar /usr/share/java

sudo mv xapool-1.3.1.jar /usr/share/java

Now you need to create soft symbolic links to each library in the Tomcat lib directory.
Navigate to the Tomcat lib directory:

cd /usr/share/tomcat6/lib

Create symbolic soft links to each library:

sudo ln -sT ../../java/slf4j-api-1.5.8.jar slf4j-api-1.5.8.jar

sudo ln -sT ../../java/slf4j-log4j12-1.5.8.jar slf4j-log4j12-1.5.8.jar

sudo ln -sT ../../java/jul-to-slf4j-1.5.8.jar jul-to-slf4j-1.5.8.jar

sudo ln -sT ../../java/jcl-over-slf4j-1.5.8.jar jcl-over-slf4j-1.5.8.jar

sudo ln -sT ../../java/log4j-1.2.16.jar log4j-1.2.16.jar

sudo ln -sT ../../java/hsqldb-1.8.0.5.jar hsqldb-1.8.0.5.jar

sudo ln -sT ../../java/jta-1.0.1B.jar jta-1.0.1B.jar

sudo ln -sT ../../java/ots-jts-1.0.jar ots-jts-1.0.jar

sudo ln -sT ../../java/jotm-1.4.3.jar jotm-1.4.3.jar

sudo ln -sT ../../java/jotm-jrmp_stubs-1.4.3.jar jotm-jrmp_stubs-1.4.3.jar

sudo ln -sT ../../java/jotm-iiop_stubs-1.4.3.jar jotm-iiop_stubs-1.4.3.jar

sudo ln -sT ../../java/jonas_timer-1.4.3.jar jonas_timer-1.4.3.jar

sudo ln -sT ../../java/objectweb-datasource-1.4.3.jar objectweb-datasource-1.4.3.jar

sudo ln -sT ../../java/carol-1.5.2.jar carol-1.5.2.jar

sudo ln -sT ../../java/carol-properties-1.5.2.jar carol-properties-1.5.2.jar

sudo ln -sT ../../java/xapool-1.3.1.jar xapool-1.3.1.jar

To prevent exceptions to logging, ensure that the following files are present in the Tomcat lib directory:

jcl-over-slf4j-x.y.z.jar

jul-to-slf4j-x.y.z.jar

log4j-x.y.z.jar

slf4j-api-x.y.z.jar

slf4j-log4j12-x-y-z.jar

You also need to ensure that the files above are not present in the webapp/jira/WEB-INF/lib subdirectory of the JIRA Installation Directory. Run the following command to list the content of the lib subdirectory:

ls /opt/atlassian-jira-5.0.6-war/webapp/WEB-INF/lib/

Step 13: Configure JIRA’s context in Tomcat

Copy the jira.xml file from the dist-tomcat6 subdirectory of your JIRA Installation Directory to the conf/Catalina/localhost subdirectory of your Tomcat installation:

sudo cp /opt/atlassian-jira-5.0.6-war/dist-tomcat/tomcat-6/jira.xml /etc/tomcat6/Catalina/localhost/

Customize the jira.xml file using the command below. Change the value assigned to docBase to /opt/atlassian-jira-5.0.6-war/dist-tomcat/tomcat-6/atlassian-jira-5.0.6.war:

sudo nano /etc/tomcat6/Catalina/localhost/jira.xml

Your docBase must look like this:

<Context path="/jira" docBase="/opt/atlassian-jira-5.0.6-war/dist-tomcat/tomcat-6/atlassian-jira-5.0.6.war" debug="0" useHttpOnly="true">

Step 14: Modify Tomcat’s server.xml to handle international characters correctly

Since this property must be specified at the connector level for your application server, this setting will affect all other web applications deployed to the same application server installation running JIRA. While this setting should not adversely affect these other web applications, you should be aware of this point.
JIRA will run fine without this property set. However, you will run into issues if a user or group is created which contains international characters. Hence, it is recommended that you set this property.
You need to modify the server.xml file in your Tomcat configuration directory by specifying

URIEncoding="UTF-8".

Run the following command to edit your server.xml file:

sudo nano /etc/tomcat6/server.xml

Step 15: Fix memory and mail handling settings in Tomcat

Tomcat effectively leaks memory by caching JSPs. This can result in OutOfMemoryError errors if large pages (such as RSS or Excel pages) are requested.
JIRA requires more memory than what Tomcat provides by default. This may lead to OutOfMemory errors when running JIRA if these memory settings are not increased.
For JIRA’s mail handler to avoid problems with RFC 2231-compliant mail clients, set the mail.mime.decodeparameters start-up parameter in Tomcat to true.
Edit Tomcat’s bin/setenv.sh file (or create this file if it does not exist) and add the following to the file:

sudo nano /usr/share/tomcat6/bin/setenv.sh

export 

CATALINA_OPTS="$CATALINA_OPTSDorg.apache.jasper.runtime.BodyContentImpl.LIMIT_BUFFER=true
 -Dmail.mime.decodeparameters=true -Xms128m -Xmx512m 
-XX:MaxPermSize=256m"

Step 16: View the Tomcat log in a separate console window

This will allow you to follow the Atlassian bootstrap process from the Tomcat log file. Open another console window and run the following command in the new window:

tail -f /var/lib/tomcat6/logs/catalina.out

Step 17: Restart Tomcat

Run the following command in your original console window:

sudo service tomcat6 restart

Step 18: Create a PostgreSQL user
Run the following commands in your console window:

sudo su - postgres

createuser -P jira

Enter password for new role:

Enter it again:

Shall the new role be a superuser? (y/n) n

Shall the new role be allowed to create databases? (y/n) y

Shall the new role be allowed to create more new roles? (y/n) n

logout

Remember the your user name and password. You will need this information when you run jita for the first time.

Step 19: Create a PostgreSQL database

Run the following commands in your console window:

sudo su - jira

createdb jiradb

exit

Step 20: Navigate to JIRA in your browser

http://servername:8080/jira

Step 21: Congratulations – You have just installed Atlassian JIRA on Ubuntu Linux

Tìm hiểu lệnh Crontab trên Linux 4

1. Cron là gì?
Cron là một tiện ích cho phép thực hiện các tác vụ một cách tự động theo định kỳ, ở chế độ nền của hệ thống. Crontab (CRON TABle) là một file chứa đựng bảng biểu (schedule) của các entries được chạy.

2. Cron làm việc thế nào?
Một cron schedule đơn giản là một text file. Mỗi người dùng có một cron schedule riêng, file này thường nằm ở /var/spool/cron. Crontab files không cho phép bạn tạo hoặc chỉnh sửa trực tiếp với bất kỳ trình text editor nào, trừ phi bạn dùng lệnh crontab. Một số lệnh thường dùng:

crontab -e: tạo hoặc chỉnh sửa file crontab
crontab -l: hiển thị file crontab
crontab -r: xóa file crontab

3. Cấu trúc của crontab
Một crontab file có 5 trường xác định thời gian, cuối cùng là lệnh sẽ được chạy định kỳ, cấu trúc như sau:
Code:

*     *     *     *     *     command to be executed
-     -     -     -     -
|     |     |     |     |
|     |     |     |     +----- day of week (0 - 6) (Sunday=0)
|     |     |     +------- month (1 - 12)
|     |     +--------- day of month (1 - 31)
|     +----------- hour (0 - 23)
+------------- min (0 - 59)

Nếu một cột được gán ký tự *, nó có nghĩa là tác vụ sau đó sẽ được chạy ở mọi giá trị cho cột đó.

4. Ví dụ
Giả sử tôi viết một đoạn script backup bookmarks trong Firefox như sau:
Code:

#!/bin/bash
date=`date +%F`

cp ~/.mozilla/firefox/13kee53o.default/bookmarks.html /mnt/data/BACKUP/bookmarks-$date.html

sau đó tôi cho script này chạy định kỳ vào 15h thứ Hai và thứ Năm hàng tuần bằng cách tạo một file crontab như sau:
Code:

$ crontab -e
0 15 * * 1,4 sh /mnt/data/linux/code/backupbookmarks.sh

Cuối cùng, nhớ khởi động lại cron daemon:
Code:

/etc/init.d/crond restart

ps: Để muốn "test" ngay xem crontab nó có hoạt động không, bạn có thể sửa lại đoạn script trên một chút:
Code:

#!/bin/bash
date=`date +%F-%H-%M-%S`

cp ~/.mozilla/firefox/13kee53o.default/bookmarks.html /mnt/data/BACKUP/bookmarks-$date.html

và file crontab bạn sẽ cho backup liên tục theo từng phút như sau:

0-59 * * * * sh /mnt/data/linux/code/backupbookmarks.sh

Tìm hiểu lệnh Crontab trên Linux 3

LINUX TOAN TAP : http://www.gocit.vn/bai-viet/tag/linux-toan-tap/

GIT- Tính năng Cron trong Linux thực chất là 1 chế độ sắp xếp tự động các chương trình, ứng dụng và kích hoạt chúng tại 1 thời điểm nhất định trong hệ thống, tương tự với Task Scheduler của Windows.

Tất cả những gì chúng ta cần làm tại đây là gán các chương trình cần thực thi tới file crontab của hệ thống và sử dụng cấu trúc lệnh phù hợp, cron sẽ tự động thực hiện các ứng dụng đó vào thời điểm đã được thiết lập sẵn trước đó. Do vậy, tính năng này rất phù hợp trong quá trình tự động sao lưu dữ liệu, bảo dưỡng hệ thống… và các công việc tương tự khác.

Cài đặt crontab bằng yum

yum install crontabs.noarch
yum install vixie-cron ( sử dụng lệnh này nếu lệnh trên không hoạt động)

Cron làm việc thế nào?
Một cron schedule đơn giản là một text file. Mỗi người dùng có một cron schedule riêng, file này thường nằm ở /var/spool/cron. Crontab files không cho phép bạn tạo hoặc chỉnh sửa trực tiếp với bất kỳ trình text editor nào, trừ phi bạn dùng lệnh crontab. Một số lệnh thường dùng:
