[. . . ] An "up2date jbossas" command will upgrade everything correctly. 5 6 Chapter 3. Installing Red Hat Application Stack To install Red Hat Application Stack V. 1. 4: 1. If you have an existing database, back up your data and shut down the database: If you are using PostgreSQL: · Back-up your database. For example, run: su rm -rf /tmp/pg. backup su - postgres /usr/bin/pg_dumpall > /tmp/pg. backup exit Note If you have large objects in the database, you need to use pg_dump instead of pg_dumpall. See http://www. postgresql. org/docs/8. 1/static/largeobjects. html and http://www. postgresql. org/docs/8. 1/static/app-pg-dumpall. html For more information, see http://www. postgresql. org/docs/8. 1/static/install-upgrading. html If you are using MySQL: · Backing-up your database is optional but recommended. Run as root: mysqldump --all-databases -p > /tmp/mysqldumpfile. sql 2. Stop the daemons: · /sbin/service httpd stop · To shut down MySQL: /sbin/service mysqld stop · To shut down PostgreSQL: /sbin/service postgresql stop 3. Install the software: · Option 1. To install from RHN, which is the preferable option to avoid dependency issues, run as root: up2date --installall rhel-i386-as-4-appstk-1 --exclude="*jbossas*" 7 Chapter 3. Installing Red Hat Application Stack up2date jbossas where rhel-i386-as-4-appstk-1 is the channel name for Red Hat Application Stack The channel names are as follows: rhel-arch-variant-4-appstk-1 where: arch = i386 or x86_64 variant = as, or es · Option 2. To install from RPMs on Disk: Follow the instructions in Section 2. 2. 2, " Using up2date / DVD " to mount the DVD and set up the local RHN channel (steps 1-3). Then as root run: up2date --installall RedHat-Application-Stack-V1 Note If you are upgrading from Stacks V. 1. 1, and have installed the jbossasejb3 package, before running the above command, you need to first remove jbossas-ejb3 manually by running as root: rpm -e jbossas-ejb3 Note You may need to install the following packages to satisfy dependencies before executing the above command, if they are not already installed: · apr-devel · apr-util-devel · libc-client · mx · pcre-devel 4. Restore your database: · For PostgreSQL: · Move (or remove) the database directory: mv /var/lib/pgsql/data /var/lib/pgsql/data. backup 8 · Start the new PostgreSQL service: /sbin/service postgresql start · Restore your data from back-up psql -U username < /tmp/pg. backup · Start the http daemon: /sbin/service httpd start · For MySQL: · Start MySQL: /sbin/service mysqld start · Update MySQL: mysql_upgrade · Restore your data: mysql -p < /tmp/mysqldumpfile. sql · Start the http daemon: /sbin/service httpd start The installation is now complete. 9 10 Chapter 4. Using JBoss AS 4. 1. Using the Linux service (production) JBoss AS can be started, stopped, and configured to start automatically at boot time either from the command line or using a graphical tool. You can start and stop the jbossas service using the service command as root on a console window (as is typical of a network service): service jbossas start . . . service jbossas stop The behavior at boot can be controlled with the chkconfig command, as any other Linux service (see chkconfig man page). Alternatively, you can issue the command system-config-services to activate the graphical Red Hat Service Configuration Tool, which can also be activated from the main menu. Select: System Settings > Server Settings > Services Note For security purposes, beginning with Red Hat Application Stack V. 1. 1, authentication for the jmx-console, web-console, jmx-invoker and http-invoker is turned on. Additionally, no user accounts are active by default, so as to prevent default user / password based attacks. · Accounts for the jmx-console and the invokers can be set up by modifying: $JBOSS_HOME/server/$CONFIG/conf/props/jmx-consoleusers. properties · Accounts for the web-console users can be set up by modifying: $JBOSS_HOME/server/$CONFIG/deploy/management/console-mgr. sar /web-console. war/WEB-INF/classes/web-consoleusers. properties Please note that the file name above has been split onto two lines for readability. It should be understood and entered as one continuous line. Where $JBOSS_HOME is the install directory (/var/lib/jbossas) and $CONFIG is the server configuration you are using. Please see http://kbase. redhat. com/faq/FAQ_107_9963. shtm for more information JBoss AS is configured with its internal servlet engine to listen for HTTP traffic on port 8080. [. . . ] Create a new config file for service-name, /etc/sysconfig/service-name. The contents of this file should be similar to /etc/sysconfig/jbossas, except with instance specific values uncommented and updated, e. g: 15 Chapter 4. Using JBoss AS cp /etc/sysconfig/jbossas /etc/sysconfig/jbossas-ports-01. Uncomment and update JBOSSCONF to ports-01 in /etc/sysconfig/jbossas-ports-01. [. . . ]
